pic Workshop 30: Jodi Picoult By audioboom.com Published On :: Wed, 02 Nov 2016 10:00:00 -0000 It’s our 30th episode, this time with the phenomenally successful Jodi Picoult. Small Great Things is her 24th novel - and the ninth straight to debut at number one on the New York Times bestseller list. If Picoult has a "thing" it's writing about thorny ethical issues from the perspective of multiple characters...and a twisty ending! She's written in the voice of suicidal teens, rape victims, a school shooter…but until now, never as a black character and never directly confronting race, privilege and inequity - which most people avoid talking about.

pic Russia’s TV channel refuse to broadcast 2018 Winter Olympics should Russia be discriminated By english.pravda.ru Published On :: Fri, 17 Nov 2017 14:20:00 +0300 Russian federal TV channels may refuse to broadcast the 2018 Winter Olympics from South Korean Pyeongchang should the Russian delegation be suspended, the Vedomosti newspaper wrote. For the time being, Russia's three major TV channels - Channel One, Rossiya-1 (part of VGTRK) and Match TV (part of Gazprom Media) plan to broadcast Winter Olympics from South Korea. Yet, if the Russian national team is excluded from the Games, Channel One and Rossiya-1 will most likely refuse to broadcast the Olympics. Naturally, Russian people watch Olympic Games to support Russian athletes in the first place. If no Russian athletes take part in the Games, the audience of the major sports event of this winter will decease sharply, representatives of the above-mentioned channels say. It makes no sense for major channels to pay millions of dollars for the rights to broadcast the Games, if they make no money from advertising because of low ratings. Full Article Sport
pic IOC wants Russia to boycott 2018 Winter Games and exit Olympic movement By english.pravda.ru Published On :: Tue, 23 Jan 2018 18:33:00 +0300 An anonymous assistant to President Putin has had a few meetings with winter sports coaches, during which he "in a mild form" recommended to refuse from participating in the Olympic Games in Pyeongchang. According to All Sports agency, an official from the Kremlin administration, whose name remains anonymous, specified that it would have to be the athletes themselves to make such a decision. The talks of the of the International Olympic Committee (IOC) commission with representatives of the Russian Olympic Committee (ROC) took place in Moscow this week. The meetings were devoted to the structure of the Russian delegation during the Games in South Korea. The next day it became known that a number of prominent Russian athletes with an unblemished reputation, including biathlete Anton Shipulin, skier Sergei Ustyugov and speed skater Victor An, as well as the leaders of hockey and speed skating teams were not invited to the competitions, even though those athletes were not listed either in Richard McLaren or Denis Oswald reports. On Tuesday, the press service of the Russian Ice Skating Federation said that the IOC did not allow Russian figure skaters Ksenia Stolbova and Ivan Bukin to participate in the 2018 Winter Games without explaining the reasons. Representatives for the Russian Ice Skating Federation expressed their indignation about the absurd decision and started to defend the honour and dignity of athletes in all possible ways.The Russian Olympic Committee prepares to give a hard estimate to IOC's actions and request appropriate explanations.Following those events, Russian politicians assumed that the IOC was pushing Russia to boycott the Winter Games 2018 and exit the Olympic movement."If no explanations follow, perhaps Russian athletes will have to revise their decision regarding the participation in the Olympics in Pyeongchang. They wanted to make us boycott the Games before, but as soon as they realised that we were not going to do it, they decided to suspend clean athletes with perfect reputations. This looks like political blackmail and creates conditions for unfair victories at the Olympics," chairman of the State Duma Committee on Physical Culture Mikhail Degtyarev told Sport Express newspaper. On December 5, the IOC Executive Committee decided that only clean Russian athletes would be able to perform at the 2018 Winter Olympics in Pyeongchang under the Olympic flag. Two special committees of the IOC have reduced the list of 500 applicants to 389 names so far. The final structure of the Russian delegation will be announced on January 28. On December 6, President Vladimir Putin announced that Russia would not boycott the Games. Pravda.Ru Full Article Sport
pic Corrupt Olympic Movement is breaking wind By english.pravda.ru Published On :: Fri, 09 Feb 2018 15:30:00 +0300 The miracle did not happen. In the morning of February 9, the Court of Arbitration for Sport (CAS) announced that it was dismissing the appeals from 47 Russian athletes against the International Olympic Committee (IOC). The athletes were in a dispute regarding the decision of the IOC not to invite them to participate in the Games in Pyeongchang. The judges decided that there was nothing to abolish because the IOC did not apply sanctions against the Russians, but distributed gifts in the form of invitations instead. A nice game of words, behind which both the IOC and WADA with their dirty deeds could hide comfortably. The IOC firmly believed that only clean Russian athletes would be able to take part in the winter Olympics in Pyeongchang. However, we will see plenty of "unclean" athletes in South Korea, albeit from other countries. Suffice it to recall German biathlonist Denise Herrmann and Polish skier Poland Justyna Kowalczyk. Both of them had been caught in doping. Christopher Del Bosco of Canada will perform in ski-cross, even though his doping test showed traces of marijuana. The position of the IOC is two-faced and cynical, and its slogans about the purity of sports are needed for something else.Elite sports have been corrupt with doping for many years, and WADA would have been set up otherwise. Big sport events always mean big money involved. How easier is it for IOC and WADA officials to make champions of the people, who had their medals supported with a nice and special thank you from sponsors? Suspending competitors appears to be a great favour to do. Russia a convenient target for WADA and IOC Russia turned out to be a very convenient target. First off, Russian athletes would always win whole baskets of medals at all Olympic competitions. Secondly, Russia remains under the sanctions of Western countries, which means that no one will stand up for Russia, and we can see it with our own eyes. This is not conspiracy - this is plain business.Most importantly, one can never find the one who bears the blame. When WADA president Craig Reedie was asked whether he would like to leave his cozy office after CAS proved the innocence of the Russians, implying that WADA had soiled itself, Reedie simply said that WADA had nothing to do with it and shifted the blame for the IOC. Why is WADA so obsessed with Russian athletes only? Why not check athletes from other countries, the Norwegians, for example? Norwegians breaking doping rules The Norwegian Broadcasting Corporation (NRK), announced without any hesitation that the national team of Norway took bags of different medications for asthma to South Korea. In particular, it goes about more than 6,000 doses! There are sick athletes in other teams, but the Swedes, the Finns and the Germans hope to get by with a considerably lower amount of doses. Interestingly, journalists of Swedish SVT television channel established that since 1992, Norwegian asthmatic athletes had won every seven out of ten Olympic medals since 1992. In Russia, children with asthma are not allowed to sports training on the level of youth sports schools. It is hard to make champions out of sick children, whose lives depend on medications. One may assume that Norway has a different approach to children's sports, implicating that the Norwegians are good at bypassing anti-doping rules.At the end of last summer, Norwegian TV channel T2 aired a report, in which former skiers of the national team said that doctors had over-medicalised them with asthma medications for prophylactic purposes. It is an open secret that regular intake of such drugs contributes to muscle growth. Famous skier Martin Sundby will apparently be the first one, who will need many doses of asthma drugs in Pyeongchang. The Olympic medalist was taking the medicine for anabolic and fat burning effects.It has been 1.5 years since January 2015 till the time when Sundby was "punished" for his rampant craving for drugs. Yet, Sundby was taking medications, collecting the money and winning the medals and that his is probably proud of. He had to return some afterwards, but the most ridiculous part of the whole story is that it took CAS a whole winter to study Sundby's addiction, but the Court of Arbitration for Sport eventually suspended the Norwegian skier for two summer (!) months. How absurd is that? Full Article Sport
pic Does Russia really want the Olympic humiliation under the white flag? By english.pravda.ru Published On :: Mon, 15 Mar 2021 21:07:00 +0300 Does Russia want its athletes humiliated at the Olympic Games again? Will Russia boycott the Games this time? Olympic alternative to Russian national anthem In December 2020, the Court of Arbitration for Sport (CAS) prohibited Russian athletes from performing at world championships and Olympic Games under the national flag and deprived them of the right to perform the Russian national anthem. To crown it all, Russia was deprived of the right to host such sports events too.A number of active Russian politicians started looking for an alternative to the Russian national anthem and picked up the idea for the Russian athletes to perform the famous WWII song "Katyusha." Some of them were not even embarrassed by the fact that the IOC requires not to include any mentioning of any war or any war-related topic in the Games, including in opening and closing ceremonies. They apparently assumed that the rest of the world should accept World War II as an excuse for Russia's current problems. On March 13, 2021, CAS rejected the request from the Russian Olympic Committee to use the "Katyusha" song as a replacement for the Russian anthem at the upcoming Olympic Games in the summer of 2021 in Tokyo and in February 2022 in Beijing. The court clarified that the concept of "any anthem associated with Russia" applied to all songs associated with Russia. However, the court decision did not close the discussion in Russia anyway, and the search for the replacement for the Russian national anthem continues. Does Russia need the white flag in sports? This is strange indeed: if Russia can stand up against the world supremacist state in Syria, return territories in Europe, ignore the work in the Council of Europe and make harsh statements about its readiness to terminate relations with the European Union, then why not slam the door to the IOC?Why should Russia should feel humiliated to participate in the Olympics? Those who believe that one needs to think about the athletes and their most important sports competitions, may forget to think that it goes about Russian athletes being Russian citizens. Does Russia need athletes that do not want to sacrifice their achievements and victories for sake of their country's dignity? Or does Russia need to live up to the interests of a handful of athletes to the detriment of its own national interests and interests of millions of other Russian citizens, who are not thrilled at the whole idea of Russia's sports humiliation?

pic Atypical phase transition, twinning and ferroelastic domain structure in bis(ethylenediammonium) tetrabromozincate(II) bromide, [NH3(CH2)2NH3]2[ZnBr4]Br2 By journals.iucr.org Published On :: 2024-11-04 Single-crystal growth, differential thermal analysis (DTA), derivative thermogravimetry (DTG), differential scanning calorimetry (DSC), X-ray structural studies and polarized microscopy observations of bis(ethylenediammonium) tetrabromozincate(II) bromide [NH3(CH2)2NH3]2[ZnBr4]Br2 are presented. A reversible phase transition is described. At room temperature, the complex crystallizes in the monoclinic system. In some cases, the single crystals are twinned into two or more large domains of ferroelastic type with domain walls in the (100) crystallographic plane. DTA and DTG measurements show chemical stability of the crystal up to ∼538 K. In the DSC studies, a reversible isostructural phase transition was revealed at ∼526/522 K on heating/cooling run, respectively. Optical observation on the heating run reveals that at the phase transition the plane of twinning (domain wall) does not disappear and additionally the appearance of a new domain structure of ferroelastic type with domain walls in the planes (101), (101), (100) and (001) is observed. The domain structure pattern is preserved after cooling to the room-temperature phase and the symmetry of this phase is unchanged. Full Article text

pic Improving the reliability of small- and wide-angle X-ray scattering measurements of anisotropic precipitates in metallic alloys using sample rotation By journals.iucr.org Published On :: 2024-11-04 Nanometric precipitates in metallic alloys often have highly anisotropic shapes. Given the large grain size and non-random texture typical of these alloys, performing small- and wide-angle X-ray scattering (SAXS/WAXS) measurements on such samples for determining their characteristics (typically size and volume fraction) results in highly anisotropic and irreproducible data. Rotations of flat samples during SAXS/WAXS acquisitions are presented here as a solution to these anisotropy issues. Two aluminium alloys containing anisotropic precipitates are used as examples to validate the approach with a −45°/45° angular range. Clear improvements can be seen on the SAXS I(q) fitting and the consistency between the different SAXS/WAXS measurements. This methodology results in more reliable measurements of the precipitate's characteristics, and thus allows for time- and space-resolved measurements with higher accuracy. Full Article text
pic Lattice symmetry relaxation as a cause for anisotropic line broadening and peak shift in powder diffraction By journals.iucr.org Published On :: 2024-10-03 In powder diffraction, lattice symmetry relaxation causes a peak to split into several components which are not resolved if the degree of desymmetrization is small (pseudosymmetry). Here the equations which rule peak splitting are elaborated for the six minimal symmetry transitions, showing that the resulting split peaks are generally broader and asymmetric, and suffer an hkl-dependent displacement with respect to the high-symmetry parent peak. These results will be of help in Rietveld refinement of pseudosymmetric structures where an exact interpretation of peak deformation is required. Full Article text
pic PEPICO analysis of catalytic reactor effluents towards quantitative isomer discrimination: DME conversion over a ZSM-5 zeolite By journals.iucr.org Published On :: 2024-06-25 The methanol-to-hydrocarbons (MTH) process involves the conversion of methanol, a C1 feedstock that can be produced from green sources, into hydrocarbons using shape-selective microporous acidic catalysts – zeolite and zeotypes. This reaction yields a complex mixture of species, some of which are highly reactive and/or present in several isomeric forms, posing significant challenges for effluent analysis. Conventional gas-phase chromatography (GC) is typically employed for the analysis of reaction products in laboratory flow reactors. However, GC is not suitable for the detection of highly reactive intermediates such as ketene or formaldehyde and is not suitable for kinetic studies under well defined low pressure conditions. Photoelectron–photoion coincidence (PEPICO) spectroscopy has emerged as a powerful analytical tool for unraveling complex compositions of catalytic effluents, but its availability is limited to a handful of facilities worldwide. Herein, PEPICO analysis of catalytic reactor effluents has been implemented at the FinEstBeAMS beamline of MAX IV Laboratory. The conversion of dimethyl ether (DME) on a zeolite catalyst (ZSM-5-MFI27) is used as a prototypical model reaction producing a wide distribution of hydrocarbon products. Since in zeolites methanol is quickly equilibrated with DME, this reaction can be used to probe vast sub-networks of the full MTH process, while eliminating or at least slowing down methanol-induced secondary reactions and catalyst deactivation. Quantitative discrimination of xylene isomers in the effluent stream is achieved by deconvoluting the coincidence photoelectron spectra. Full Article text
pic Borotropic shifting of the hydrotris[3-(2-furyl)pyrazol-1-yl]borate ligand in high-coordinate lanthanide complexes By journals.iucr.org Published On :: 2024-04-16 The coordination of hydrotris[3-(2-furyl)pyrazol-1-yl]borate (Tp2-Fu, C21H16BN6O3) to lanthanide(III) ions is achieved for the first time with the complex [Ln(Tp2-Fu)2](BPh4)·xCH2Cl2 (1-Ln has Ln = Ce and x = 2; 1-Dy has Ln = Dy and x = 1). This was accomplished via both hydrous (Ln = Ce) and anhydrous methods (Ln = Dy). When isolating the dysprosium analogue, the filtrate produced a second crop of crystals which were revealed to be the 1,2-borotropic-shifted product [Dy(κ4-Tp2-Fu)(κ5-Tp2-Fu*)](BPh4) (2) {Tp2-Fu* = hydrobis[3-(2-furyl)pyrazol-1-yl][5-(2-furyl)pyrazol-1-yl]borate}. We conclude that the presence of a strong Lewis acid and a sterically crowded coordination environment are contributing factors for the 1,2-borotropic shifting of scorpionate ligands in conjunction with the size of the conical angle with the scorpionate ligand.

Stepwise consecutive reaction of [Mn(C5Br5)(PPh3)(CO)2] with n-BuLi and MeSSMe led finally to [Mn{C5(SMe)5}(PPh3)(CO)2] (11), only the fifth complex to be reported containing a perthiolated cyclopentadienyl ring. The molecular and crystal structures of 1b, 3, 4 and 11 were determined and were studied for the occurrence of S⋯S and S⋯Br interactions. It turned out that although some interactions of this type occurred, they were of minor importance for the arrangement of the molecules in the crystal. Full Article text
pic Cocrystals of a coumarin derivative: an efficient approach towards anti-leishmanial cocrystals against MIL-resistant Leishmania tropica By journals.iucr.org Published On :: 2024-03-01 Leishmaniasis is a neglected parasitic tropical disease with numerous clinical manifestations. One of the causative agents of cutaneous leishmaniasis (CL) is Leishmania tropica (L. tropica) known for causing ulcerative lesions on the skin. The adverse effects of the recommended available drugs, such as amphotericin B and pentavalent antimonial, and the emergence of drug resistance in parasites, mean the search for new safe and effective anti-leishmanial agents is crucial. Miltefosine (MIL) was the first recommended oral medication, but its use is now limited because of the rapid emergence of resistance. Pharmaceutical cocrystallization is an effective method to improve the physicochemical and biological properties of active pharmaceutical ingredients (APIs). Herein, we describe the cocrystallization of coumarin-3-carboxylic acid (CU, 1a; 2-oxobenzopyrane-3-carboxylic acid, C10H6O4) with five coformers [2-amino-3-bromopyridine (1b), 2-amino-5-(trifluoromethyl)-pyridine (1c), 2-amino-6-methylpyridine (1d), p-aminobenzoic acid (1e) and amitrole (1f)] in a 1:1 stoichiometric ratio via the neat grinding method. The cocrystals 2–6 obtained were characterized via single-crystal X-ray diffraction, powder X-ray diffraction, differential scanning calorimetry and thermogravimetric analysis, as well as Fourier transform infrared spectroscopy. Non-covalent interactions, such as van der Waals, hydrogen bonding, C—H⋯π and π⋯π interactions contribute significantly towards the packing of a crystal structure and alter the physicochemical and biological activity of CU. In this research, newly synthesized cocrystals were evaluated for their anti-leishmanial activity against the MIL-resistant L. tropica and cytotoxicity against the 3T3 (normal fibroblast) cell line. Among the non-cytotoxic cocrystals synthesized (2–6), CU:1b (2, IC50 = 61.83 ± 0.59 µM), CU:1c (3, 125.7 ± 1.15 µM) and CU:1d (4, 48.71 ± 0.75 µM) appeared to be potent anti-leishmanial agents and showed several-fold more anti-leishmanial potential than the tested standard drug (MIL, IC50 = 169.55 ± 0.078 µM). The results indicate that cocrystals 2–4 are promising anti-leishmanial agents which require further exploration. Full Article text
pic Evolution of structure and spectroscopic properties of a new 1,3-diacetylpyrene polymorph with temperature and pressure By journals.iucr.org Published On :: 2024-05-10 A new polymorph of 1,3-diacetylpyrene has been obtained from its melt and thoroughly characterized using single-crystal X-ray diffraction, steady-state UV–Vis spectroscopy and periodic density functional theory calculations. Experimental studies covered the temperature range from 90 to 390 K and the pressure range from atmospheric to 4.08 GPa. Optimal sample placement in a diamond anvil cell according to our previously presented methodology ensured over 80% data coverage up to 0.8 Å for a monoclinic sample. Unrestrained Hirshfeld atom refinement of the high-pressure crystal structures was successful and anharmonic behavior of carbonyl oxygen atoms was observed. Unlike the previously characterized polymorph, the structure of 2°AP-β is based on infinite π-stacks of antiparallel 2°AP molecules. 2°AP-β displays piezochromism and piezofluorochromism which are directly related to the variation in interplanar distances within the π-stacking. The importance of weak intermolecular interactions is reflected in the substantial negative thermal expansion coefficient of −55.8 (57) MK−1 in the direction of C—H⋯O interactions. Full Article text
pic Scanning WAXS microscopy of regenerated cellulose fibers at mesoscopic resolution By journals.iucr.org Published On :: 2024-06-11 In this work, regenerated cellulose textile fibers, Ioncell-F, dry-wet spun with different draw ratios, have been investigated by scanning wide-angle X-ray scattering (WAXS) using a mesoscopic X-ray beam. The fibers were found to be homogeneous on the 500 nm length scale. Analysis of the azimuthal angular dependence of a crystalline Bragg spot intensity revealed a radial dependence of the degree of orientation of crystallites that was found to increase with the distance from the center of the fiber. We attribute this to radial velocity gradients during the extrusion of the spin dope and the early stage of drawing. On the other hand, the fiber crystallinity was found to be essentially homogeneous over the fiber cross section. Full Article text

pic Crystallographic phase identifier of a convolutional self-attention neural network (CPICANN) on powder diffraction patterns By journals.iucr.org Published On :: 2024-06-27 Spectroscopic data, particularly diffraction data, are essential for materials characterization due to their comprehensive crystallographic information. The current crystallographic phase identification, however, is very time consuming. To address this challenge, we have developed a real-time crystallographic phase identifier based on a convolutional self-attention neural network (CPICANN). Trained on 692 190 simulated powder X-ray diffraction (XRD) patterns from 23 073 distinct inorganic crystallographic information files, CPICANN demonstrates superior phase-identification power. Single-phase identification on simulated XRD patterns yields 98.5 and 87.5% accuracies with and without elemental information, respectively, outperforming JADE software (68.2 and 38.7%, respectively). Bi-phase identification on simulated XRD patterns achieves 84.2 and 51.5% accuracies, respectively. In experimental settings, CPICANN achieves an 80% identification accuracy, surpassing JADE software (61%). Integration of CPICANN into XRD refinement software will significantly advance the cutting-edge technology in XRD materials characterization. Full Article text
pic Synthesis, structural and spectroscopic characterization of defect-rich forsterite as a representative phase of Martian regolith By journals.iucr.org Published On :: 2024-10-28 Regolith draws intensive research attention because of its importance as the basis for fabricating materials for future human space exploration. Martian regolith is predicted to consist of defect-rich crystal structures due to long-term space weathering. The present report focuses on the structural differences between defect-rich and defect-poor forsterite (Mg2SiO4) – one of the major phases in Martian regolith. In this work, forsterites were synthesized using reverse strike co-precipitation and high-energy ball milling (BM). Subsequent post-processing was also carried out using BM to enhance the defects. The crystal structures of the samples were characterized by X-ray powder diffraction and total scattering using Cu and synchrotron radiation followed by Rietveld refinement and pair distribution function (PDF) analysis, respectively. The structural models were deduced by density functional theory assisted PDF refinements, describing both long-range and short-range order caused by defects. The Raman spectral features of the synthetic forsterites complement the ab initio simulation for an in-depth understanding of the associated structural defects. Full Article text
pic Crystal structures of the isotypic complexes bis(morpholine)gold(I) chloride and bis(morpholine)gold(I) bromide By journals.iucr.org Published On :: 2023-11-16 The compounds bis(morpholine-κN)gold(I) chloride, [Au(C4H9NO)2]Cl, 1, and bis(morpholine-κN)gold(I) bromide, [Au(C4H9NO)2]Br, 2, crystallize isotypically in space group C2/c with Z = 4. The gold atoms, which are axially positioned at the morpholine rings, lie on inversion centres (so that the N—Au—N coordination is exactly linear) and the halide anions on twofold axes. The residues are connected by a classical hydrogen bond N—H⋯halide and by a short gold⋯halide contact to form a layer structure parallel to the bc plane. The morpholine oxygen atom is not involved in classical hydrogen bonding. Full Article text
pic Crystal structure reinvestigation and spectroscopic analysis of tricadmium orthophosphate By journals.iucr.org Published On :: 2023-11-14 Single crystals of tricadmium orthophosphate, Cd3(PO4)2, have been synthesized successfully by the hydrothermal route, while its powder form was obtained by a solid-solid process. The corresponding crystal structure was determined using X-ray diffraction data in the monoclinic space group P21/n. The crystal structure consists of Cd2O8 or Cd2O10 dimers linked together by PO4 tetrahedra through sharing vertices or edges. Scanning electron microscopy (SEM) was used to investigate the morphology and to confirm the chemical composition of the synthesized powder. Infrared analysis corroborates the presence of isolated phosphate tetrahedrons in the structure. UV–Visible studies showed an absorbance peak at 289 nm and a band gap energy of 3.85 eV, as determined by the Kubelka–Munk model. Full Article text
pic Crystal structure and Hirshfeld surface analysis of 2-picolyllithium·3thf By journals.iucr.org Published On :: 2024-01-01 In the title compound, (2-methylidene-1,2-dihydropyridinium-κN)tris(tetrahydrofuran-κO)lithium, [Li(C6H6N)(C4H8O)3], the lithium ion adopts a distorted LiNO3 tetrahedral coordination geometry and the 2-picolyl anion adopts its enamido form with the lithium ion lying close to the plane of the pyridine ring. A methylene group of one of the thf ligands is disordered over two orientations. In the crystal, a weak C—H⋯O interaction generates inversion dimers. A Hirshfeld surface analysis shows that H⋯H contacts dominate the packing (86%) followed by O⋯H/H⋯O and C⋯H/H⋯C contacts, which contribute 3% and 10.4%, respectively. Full Article text
pic Synthesis, spectroscopic analysis and crystal structure of (N-{2-[(2-aminoethyl)amino]ethyl}-4'-methyl-[1,1'-biphenyl]-4-sulfonamidato)tricarbonylrhenium(I) By journals.iucr.org Published On :: 2024-06-18 The title compound, [Re(C17H22N3O2S)(CO)3] is a net neutral fac-Re(I)(CO)3 complex of the 4-methylbiphenyl sulfonamide derivatized diethylenetriamine ligand. The NNN-donor monoanionic ligand coordinates with the Re core in tridentate fashion, establishing an inner coordination sphere resulting in a net neutral complex. The complex possesses pseudo-octahedral geometry where one face of the octahedron is occupied by three carbonyl ligands and the other faces are occupied by one sp2 nitrogen atom of the sulfonamide group and two sp3 nitrogen atoms of the dien backbone. The Re—Nsp2 bond distance, 2.173 (4) Å, is shorter than the Re—Nsp3 bond distances, 2.217 (5) and 2.228 (6) Å, and is similar to the range reported for typical Re—Nsp2 bond lengths (2.14 to 2.18 Å).

pic We Just Got Our Clearest Picture Yet Of How Biden Won In 2020 By www.scpr.org Published On :: Wed, 30 Jun 2021 13:20:07 -0700 Incoming President Biden and Vice President Harris stand with their respective spouses Jill Biden and Doug Emhoff after delivering remarks in Wilmington, Del., on Nov. 7, the day the Democrats were declared the winners in the 2020 election.; Credit: Jim Watson/AFP via Getty Images Danielle Kurtzleben | NPRWe know that President Biden won the 2020 election (regardless of what former President Donald Trump and his allies say). We just haven't had a great picture of how Biden won. That is until Wednesday, when we got the clearest data yet on how different groups voted, and crucially, how those votes shifted from 2016. The Pew Research Center just released its validated voters' report, considered a more accurate measure of the electorate than exit polls, which have the potential for significant inaccuracies. The new Pew data shows that shifts among suburban voters, white men and independents helped Biden win in November, even while white women and Hispanics swung toward Trump from 2016 to 2020. To compile the data, Pew matches up survey respondents with state voter records. Those voter files do not say how a person voted, but they do allow researchers to be sure that a person voted, period. That helps with accuracy, eliminating the possibility of survey respondents overreporting their voting activity. In addition, the Pew study uses large samples of Americans — more than 11,000 people in 2020. It's a numbers-packed report, but there are some big takeaways about what happened in 2020 (and what it might tell us about 2022 and beyond): Suburban voters (especially white suburban voters) swung toward Biden Suburban voters appear to have been a major factor helping Biden win. While Pew found Trump winning the suburbs by 2 points in 2016, Biden won them by 11 points in 2020, a 13-point overall swing. Considering that the suburbs accounted for just over half of all voters, it was a big demographic win for Biden. That said, Trump gained in both rural and urban areas. He won 65% of rural voters, a 6-point jump from 2016. And while cities were still majority-Democratic, his support there jumped by 9 points, to 33%. Men (especially white men) swung toward Biden In 2020, men were nearly evenly split, with 48% choosing Biden to Trump's 50%. That gap shrank considerably from 2016, when Trump won men by 11 points. In addition, this group that swung away from Trump grew as a share of the electorate from 2016 — signaling that in a year with high turnout, men's turnout grew more. White men were a big part of the swing toward Biden. In 2016, Trump won white men by 30 points. In 2020, he won them again, but by a substantially slimmer 17 points. In addition, Biden made significant gains among married men and college-educated men. All of these groups overlap, but they help paint a more detailed portrait of the type of men who might have shifted or newly participated in 2020. However, we can't know from this data what exactly was behind these shifts among men — for example, exactly what share of men might have sat on the sidelines in 2016, as opposed to 2020. Women (especially white women) swung toward Trump The idea that a majority of white women voted for Trump quickly became one of the 2016 election's most-cited statistics, as many Hillary Clinton supporters — particularly women — were outraged to see other women support Trump. While that statistic was repeated over and over, Pew's data ultimately said this wasn't true — they found that in 2016, white women were split 47% to 45%, slightly in Trump's favor but not a majority. This year, however, it appears that Trump did win a majority of white women. Pew found that 53% of white women chose Trump this year, up by 6 points from 2016. This support contributed to an overall shift in women's numbers — while Clinton won women of all races by 15 points in 2016, Biden won them by 11 points in 2020. Combined with men's shifts described above, it shrank 2016's historic gender gap. Notably, the swing in white women's margin (5 points altogether) was significantly smaller than white men's swing toward Biden (13 points altogether). Hispanic voters swung toward Trump Trump won 38% of Hispanic voters in 2020, according to Pew, up from 28% in 2016. That 38% would put Trump near George W. Bush's 40% from 2004 — a recent high-water mark for Republicans with Hispanic voters. That share fell off substantially after 2004, leading some Republican pollsters and strategists to wonder how the party could regain that ground. Trump in 2016 intensified those fears, with his nativist rhetoric and hard-line immigration policies. There are some important nuances to these Hispanic numbers. Perhaps most notably, there is a sizable education gap. Biden won college-educated Hispanic voters by 39 points, but the Democrat won those with some college education or less by 14 points. That gap mirrors the education gap regularly seen in the broader voting population. Unfortunately, Pew's sample sizes from 2016 weren't big enough to break down Hispanic voters by gender that year, so it's impossible to see if this group's gender gap widened. Nonwhite voters leaned heavily toward Biden Unlike white and Hispanic voters, Black voters didn't shift significantly from 2016. They remained Democratic stalwarts, with 92% choosing Biden — barely changed from four years earlier. Nearly three-quarters of Asian voters also voted for Biden, along with 6 in 10 Hispanic voters and 56% of voters who chose "other" as their race. (Those groups' sample sizes also weren't big enough in 2016 to draw a comparison over time.) 2018 trends stuck around ... but diminished In many of these cases where there were substantial shifts in how different groups voted, they weren't surprising, given how voters in the last midterms voted. For example, white men voted more for Democrats in 2018 than they did in 2016, as did suburban voters. What it means for 2022 The data signals that Democrats' strength with Hispanic voters has eroded, but that the party succeeded in making further inroads in the suburbs, including among suburban whites. It suggests that these groups, already major focuses for both parties, will continue to be so in 2022, with Republicans trying to cement their gains among Hispanics (and regain suburban voters), while Democrats do Hispanic outreach and try to hold onto the suburbs. However, it's hard to project much into the future about what voters will do based on the past two elections because of their unique turnout numbers. "It's hard to interpret here, because 2018 was such a high turnout midterm election, and then our last data point, 2014, was a historically low turnout midterm election," said Ruth Igielnik, senior researcher at Pew Research Center.

pic Tropical Storm Elsa Is Lashing Cuba And Has Florida Next In Its Sights By www.scpr.org Published On :: Mon, 05 Jul 2021 10:00:09 -0700 Dan Charles | NPR Updated July 5, 2021 at 11:33 AM ET A tropical storm with 65-mile-an-hour winds is drenching Cuba, and is expected to reach Key West and the west coast of Florida within the next 48 hours. The National Hurricane Center expects Tropical Storm Elsa to drop between 5 and 10 inches of rain on central and western Cuba, leading to significant flooding and mudslides. The storm probably will weaken somewhat as it crosses the island, but could strengthen again as it approaches Florida. According to the Associated Press, Cuban officials evacuated 180,000 people as a precaution against the possibility of heavy flooding. Most of those evacuated stayed at relatives' homes, others went to government shelters, and hundreds living in mountainous areas took refuge in caves prepared for emergencies. The storm had killed at least three people on other Caribbean islands before it reached Cuba The National Weather Service says that the western coast of Florida, including Tampa Bay, can expect a storm surge that would lift water levels between two and four feet. Much of Florida could see heavy rainfall that could reach six inches in some places. The storm will then bring heavy rains to Georgia and the Carolinas later in the week. Florida officials were worried that the storm could destabilize what was left of the condominium building that partially collapsed over a week ago. In order to avoid an uncontrolled collapse, they approved the demolition of the remaining portion of the building, which took place on Sunday night. "The hurricane was coming, the potential for that building to fall on the pile with the victims in it was a tragic thought," Surfside Mayor Charles Burkett told NPR on Monday. It's early in the hurricane season. The National Oceanic and Atmospheric Administration has predicted a busier-than-average Atlantic hurricane season, but it would be hard to top last year's, which set an all-time record with 30 named storms. Tropical storms are fueled by warm water in the upper layers of the ocean, and ocean temperatures have been rising as heat is trapped by greenhouse gases. Copyright 2021 NPR.
