In the title compound, C25H17NO3, the torsion angle associated with the phenyl benzoate group is −173.7 (2)° and that for the benz­yloxy group is −174.8 (2)° establishing an anti-type conformation. The dihedral angles between the ten-membered cyanona­phthalene ring and the aromatic ring of the phenyl benzoate and the benz­yloxy fragments are 40.70 (10) and 87.51 (11)°, respectively, whereas the dihedral angle between the aromatic phenyl benzoate and the benz­yloxy fragments is 72.30 (13)°. In the crystal, the mol­ecules are linked by weak C—H⋯O inter­actions forming S(4) chains propagating parallel to [010]. The packing is consolidated by three C—H⋯π inter­actions and two π–π stacking inter­actions between the aromatic rings of naphthalene and phenyl benzoate with centroid-to-centroid distances of 3.9698 (15) and 3.8568 (15) Å, respectively. Inter­molecular inter­actions were qu­anti­fied using Hirshfeld surface analysis. The mol­ecular structure was further optimized by density functional theory (DFT) at the B3LYP/6–311+ G(d,p) level, revealing that the energy gap between HOMO and LUMO is 3.17 eV. Mol­ecular docking studies were carried out for the title compound as a ligand and SARS-Covid-2(PDB ID:7QF0) protein as a receptor giving a binding affinity of −9.5 kcal mol−1.

Developing semiconductor devices requires a fast and reliable source of strain information with high spatial resolution and strain sensitivity. This work investigates the strain in an axially heterostructured 180 nm-diameter GaInP nanowire with InP segments of varying lengths down to 9 nm, simultaneously probing both materials. Scanning X-ray diffraction (XRD) is compared with Bragg projection ptychography (BPP), a fast single-projection method. BPP offers a sufficient spatial resolution to reveal fine details within the largest segments, unlike scanning XRD. The spatial resolution affects the quantitative accuracy of the strain maps, where BPP shows much-improved agreement with an elastic 3D finite element model compared with scanning XRD. The sensitivity of BPP to small deviations from the Bragg condition is systematically investigated. The experimental confirmation of the model suggests that the large lattice mismatch of 1.52% is accommodated without defects.

Hendrickson & Lattman [Acta Cryst. (1970), B26, 136–143] introduced a method for representing crystallographic phase probabilities defined on the unit circle. Their approach could model the bimodal phase probability distributions that can result from experimental phase determination procedures. It also provided simple and highly effective means to combine independent sources of phase information. The present work discusses the equivalence of the Hendrickson–Lattman distribution and the generalized von Mises distribution of order two, which has been studied in the statistical literature. Recognizing this connection allows the Hendrickson–Lattman distribution to be expressed in an alternative form which is easier to interpret, as it involves the location and concentration parameters of the component von Mises distributions. It also allows clarification of the conditions for bimodality and access to a simplified analytical method for evaluating the trigonometric moments of the distribution, the first of which is required for computing the best Fourier synthesis in the presence of phase, but not amplitude, uncertainty.

Neutron spectroscopy uniquely and non-destructively accesses diffusive dynamics in soft and biological matter, including for instance proteins in hydrated powders or in solution, and more generally dynamic properties of condensed matter on the molecular level. Given the limited neutron flux resulting in long counting times, it is important to optimize data acquisition for the specific question, in particular for time-resolved (kinetic) studies. The required acquisition time was recently significantly reduced by measurements of discrete energy transfers rather than quasi-continuous neutron scattering spectra on neutron backscattering spectrometers. Besides this reduction in acquisition times, smaller amounts of samples can be measured with better statistics, and most importantly, kinetically changing samples, such as aggregating or crystallizing samples, can be followed. However, given the small number of discrete energy transfers probed in this mode, established analysis frameworks for full spectra can break down. Presented here are new approaches to analyze measurements of diffusive dynamics recorded within fixed windows in energy transfer, and these are compared with the analysis of full spectra. The new approaches are tested by both modeled scattering functions and a comparative analysis of fixed energy window data and full spectra on well understood reference samples. This new approach can be employed successfully for kinetic studies of the dynamics focusing on the short-time apparent center-of-mass diffusion.

Geological formations provide a promising environment for the long-term and short-term storage of gases, including carbon dioxide, hydrogen and hydro­carbons, controlled by the rock-specific small-scale pore structure. This study investigates the nanoscale structure and gas uptake in a highly porous silica aerogel (a synthetic proxy for natural rocks) using transmission electron microscopy, X-ray diffraction, and small-angle and ultra-small-angle neutron scattering with a tracer of deuterated methane (CD4) at pressures up to 1000 bar. The results show that the adsorption of CD4 in the porous silica matrix is scale dependent. The pore space of the silica aerogel is fully accessible to the invading gas, which quickly equilibrates with the external pressure and shows no condensation on the sub-nanometre scale. In the 2.5–50 nm pore size region a classical two-phase adsorption behaviour is observed. The structure of the aerogel returns to its original state after the CD4 pressure has been released.

The increasing structural complexity and downscaling of modern nanodevices require continuous development of structural characterization techniques that support R&D and manufacturing processes. This work explores the capability of laboratory characterization of periodic planar nanostructures using 3D X-ray standing waves as a promising method for reconstructing atomic profiles of planar nanostructures. The non-destructive nature of this metrology technique makes it highly versatile and particularly suitable for studying various types of samples. Moreover, it eliminates the need for additional sample preparation before use and can achieve sub-nanometre reconstruction resolution using widely available laboratory setups, as demonstrated on a diffractometer equipped with a microfocus X-ray tube with a copper anode.

Small-angle neutron scattering is a widely used technique to study large-scale structures in bulk samples. The largest accessible length scale in conventional Bragg scattering is determined by the combination of the longest available neutron wavelength and smallest resolvable scattering angle. A method is presented that circumvents this limitation and is able to extract larger length scales from the low-q power-law scattering using a modification of the well known Porod law connecting the scattered intensity of randomly distributed objects to their specific surface area. It is shown that in the special case of a highly aligned domain structure the specific surface area extracted from the modified Porod law can be used to determine specific length scales of the domain structure. The analysis method is applied to study the micrometre-sized domain structure found in the intermediate mixed state of the superconductor niobium. The analysis approach allows the range of accessible length scales to be extended from 1 µm to up to 40 µm using a conventional small-angle neutron scattering setup.

Semi-retired, former LA Times food writer Russ Parsons appeared often on Off-Ramp over the years, helping to explain the city’s communities through their food, as well as giving solid cooking advice. For the final edition of Off-Ramp, John picked up Russ at Jongewaard's Bake-N-Broil, a Long Beach institution.

Parsons brought John an olallieberry pie (a cross of 'Black Logan' blackberries and youngberries), whilst the inimitable Parsons -- author of "How to Pick a Peach: The Search for Flavor from Farm to Table" and "How to Read a French Fry: And Other Stories of Intriguing Kitchen Science" -- opted for the coconut cream.

Listen to the audio for John and Russ' observations on how food brings the disparate cultures of Los Angeles together, and to hear about which part of hosting Off-Ramp is as humbling for John as it is for Parsons when readers tell him they cook his food at Thanksgiving.

Gay and bisexual men in England, Scotland, and Wales can now donate blood, plasma and platelets under certain circumstances without having to wait three months, the National Health Service announced this week.; Credit: Wilfredo Lee/AP

Gay and bisexual men in England, Scotland, and Wales can now donate blood, plasma and platelets under certain circumstances, the National Health Service announced this week in a momentous shift in policy for most of the U.K.

Beginning Monday, gay men in sexually active, monogamous relationships for at least three months can donate for the first time. The move reverses a policy that limited donor eligibility on perceived risks of contracting HIV/AIDs and other sexually transmitted infections.

The new rules come as the U.K. and other countries around the world report urgent, pandemic-induced blood supply issues.

Donor eligibility will now be based on each person's individual circumstances surrounding health, travel and sexual behaviors regardless of gender, according to the NHS. Potential donors will no longer be asked if they are a man who has had sex with another man, but they will be asked about recent sexual activity.

Anyone who has had the same sexual partner for the last three months can donate, the NHS said.

"Patient safety is at the heart of everything we do. This change is about switching around how we assess the risk of exposure to a sexual infection, so it is more tailored to the individual," said Ella Poppitt, Chief Nurse for blood donation at NHS Blood and Transplant, in a statement. "We screen all donations for evidence of significant infections, which goes hand-in-hand with donor selection to maintain the safety of blood sent to hospitals."

People who engage in anal sex with a new partner or multiple people or who have recently used PrEP or PEP (medication used to prevent HIV infection) will have to wait three months to donate - regardless of their gender.

Why did the U.K. make this change?

The NHS moved to alter its blood donation eligibility rules following a review by the FAIR (For the Assessment of Individualised Risk) steering group. The panel determined an individualized, gender-neutral approach to determining who can donate blood, platelets, and plasma is fairer and still maintains the safety of the U.K.'s blood supply.

The findings were accepted in full by the government last December.

Researchers will continue to monitor the impact of the donor selection changes for the next 12 months to determine if more changes are needed, NHS said.

What is the policy in the U.S.?

Despite efforts by advocates to change regulations in the U.S, the ability for gay and bisexual men to donate blood is still restricted.

A ban on gay and bisexual blood donors has been in effect since the early 1980s when fears about HIV/AIDS were widespread.

The Food and Drug Administration's current policy states a man who has sex with another man in the previous three months can't donate. Federal rules previously made such donors wait 12 months before giving blood, but due to low blood supplies during the pandemic the federal government changed the policy in April.

The Red Cross said they are participating in a pilot study funded by the FDA using behavior-based health history questionnaires, similar to those used in the U.K.
