Twelve 4-(4-meth­oxy­phen­yl)piperazin-1-ium salts containing organic anions have been prepared and structurally characterized. The monohydrated benzoate, 4-fluoro­benzoate, 4-chloro­benzoate and 4-bromo­benzoate salts, C11H17N2O+·C7H5O2−·H2O (I), C11H17N2O+·C7H4FO2−·H2O (II), C11H17N2O+·C7H4ClO2−·H2O (III), and C11H17N2O+·C7H4BrO2−·H2O (IV), respectively, are isomorphous and all exhibit disorder in the 4-meth­oxy­phenyl unit: the components are linked by N—H⋯O and O—H⋯O hydrogen bond to form chains of rings. The unsolvated 2-hy­droxy­benzoate, pyridine-3-carboxyl­ate and 2-hy­droxy-3,5-di­nitro­benzoate salts, C11H17N2O+·C7H5O3− (V), C11H17N2O+·C6H4NO2− (VI) and C11H17N2O+·C7H3N2O7− (VII), respectively, are all fully ordered: the components of (V) are linked by multiple N—H⋯O hydrogen bonds to form a chain of rings; those of (VI) are linked into a three-dimensional framework by a combination of N—H⋯O, C—H⋯O and C—H⋯N hydrogen bonds and those of (VII), where the anion has a structure reminiscent of the picrate anion, are linked into a three-dimensional array by N—H⋯O and C—H⋯O hydrogen bonds. The hydrogensuccinate and hydrogenfumarate salts, C11H17N2O+·C4H5O4− (VIII) and C11H17N2O+·C4H3O3− (IX), respectively, are isomorphous, and both exhibit disorder in the anionic component: N—H⋯O and O—H⋯O hydrogen bonds link the ions into sheets, which are further linked by C—H⋯π(arene) inter­actions. The anion of the hydrogenmaleate salt, C11H17N2O+·C4H3O3− (X), contains a very short and nearly symmetrical O⋯H⋯O hydrogen bond, and N—H⋯O hydrogen bonds link the anions into chains of rings. The ions in the tri­chloro­acetate salt, C11H17N2O+·C2Cl3O2− (XI), are linked into simple chains by N—H⋯O hydrogen bonds. In the hydrated chloranilate salt, 2C11H17N2O+·C6Cl2O42−·2H2O (XII), which crystallizes as a non-merohedral twin, the anion lies across a centre of inversion in space group P21/n, and a combination of N—H⋯O and O—H⋯O hydrogen bonds generates complex sheets. Comparisons are made with the structures of some related compounds.

A mixed alkaline-earth powellite, Ca0.84Sr0.16MoO4 (calcium strontium molybdate), was synthesized by a flux method and its crystal structure was solved using single-crystal X-ray diffraction (SC-XRD) data. The compound crystallized in the I41/a space group as with a typical CaMoO4 powellite, but with larger unit-cell parameters and unit-cell volume as a result of the partial incorporation of larger Sr cations into the Ca sites within the crystal. The unit cell and volume were well fitted with the trendline calculated from literature values, and the powder X-ray diffraction (P-XRD) pattern of the ground crystal is in good agreement with the calculated pattern from the solved structure.

Serial crystallography is having an increasing impact on structural biology. This emerging technique opens up new possibilities for studying protein structures at room temperature and investigating structural dynamics using time-resolved X-ray diffraction. A limitation of the method is the intrinsic need for large quantities of well ordered micrometre-sized crystals. Here, a method is presented to screen for conditions that produce microcrystals of membrane proteins in the lipidic cubic phase using a well-based crystallization approach. A key advantage over earlier approaches is that the progress of crystal formation can be easily monitored without interrupting the crystallization process. In addition, the protocol can be scaled up to efficiently produce large quantities of crystals for serial crystallography experiments. Using the well-based crystallization methodology, novel conditions for the growth of showers of microcrystals of three different membrane proteins have been developed. Diffraction data are also presented from the first user serial crystallography experiment performed at MAX IV Laboratory.

Book review

Described here are instructions for building and using an inexpensive automated microscope (AMi) that has been specifically designed for viewing and imaging the contents of multi-well plates. The X, Y, Z translation stage is controlled through dedicated software (AMiGUI) that is being made freely available. Movements are controlled by an Arduino-based board running grbl, and the graphical user interface and image acquisition are controlled via a Raspberry Pi microcomputer running Python. Images can be written to the Raspberry Pi or to a remote disk. Plates with multiple sample wells at each row/column position are supported, and a script file for automated z-stack depth-of-field enhancement is written along with the images. The graphical user interface and real-time imaging also make it easy to manually inspect and capture images of individual samples.

A recent survey of the bottom-dwelling animals of the Chesapeake has revealed that communities of even these relatively hardy organisms are under stress. Many regions of the bay are becoming inhospitable to bottom-dwelling animals because of a lack of oxygen—a condition known as “hypoxia.”

Dear Off-Ramp fans,

What is a blog, after all? Words and images.

And what is a radio story on the web? Words, images, and sound.

Can't they live together in harmony? We say YES.

And with that in mind, we're killing the Off-Ramp blog page.  

But don't fear; we're not cutting back on content: everything that would have found a home here - Marc Haefele's art reviews, recommendations for fun events, etc. -- will now be on the regular web page of the Off-Ramp radio show. 

All the old blog entries will continue to stay on this page as an archive, like Catherine Deneuve's fading vampire lovers in The Hunger.

What shall we call this color scheme? How about ‘Manhattan Mermaid’?

The petrel blues, the turquoises, the aquas – and then that uptown/downtown black, in this case a black linen duster over a Peter Max-style splashy-print silk dress. The way the hem pools at the sides a bit reminds me of the cut of Pre-Raphaelite ladies’ tunics; I’d love to dress “period” for a week to see whether I’d like it.

Imagine, a week of hoop skirts … a week of 1950s tailleurs … a week of bustles … a week of hobble skirts … a week of liberated Pre-Raphaelite velvet gowns!

The hat is so unmistakably summer in fabric and color that it doesn’t get out of the hatbox as much as it should, poor thing. And the shoes – I did not get them together, honest, but even though the prints don’t match, it’s the dissonance that makes them work better together than if they had.

The fabric is a very textured canvas and printed like batik. [They are not the soul of comfort – oh what a dreadful pun, but is there any other kind of pun? – but they look smart hooked over the railing of a chair in a chic bistro, which is where I intend to take them!]

And the bracelets, one from a great-aunt who had a fine eye for jewelry – the turquoise is almost Persian, it’s so green, but it’s more likely to be American. The cuff is definitely Southwest, with the rope-pattern trim and the irregularly shaped bezels, although the turquoises themselves are symmetrical.

Because I’m left-handed, my right arm bears the singular honor of being “ornamental,” and bearing the burden of the bling.

Summer on, ladies!

Using data gathered by satellites, scientists have monitored changes in fishing activity around Italy in the Mediterranean Sea for the period 2007-2010. From this, they developed new ecological indicators that gave a more detailed pattern of fishing activity in the Italian seas. In addition, the new indicators suggest that fish stocks on the seabed around Italy are continuing to decline.

The impact of air quality on public welfare is important to policy development. However, it is difficult to make a clear link between the two when air pollution tends to be reported at a country level and wellbeing is an individual measure. A new study takes a step further towards linking the two by analysing regional level air quality across the EU and relating it to levels of life satisfaction.

The importance of comprehensive flood emergency plans is becoming increasingly recognised. A new study has evaluated plans in England and Wales, France and the Netherlands. It was found that, although plans perform well in terms of organisation and communication, they are lacking in more technical aspects, such as the provision of flood hazard maps and evacuation plans.

A recent report has reviewed research on the effectiveness of low-noise road surfaces, taking into account acoustic performance, safety, skidding resistance and cost. It concludes they could have substantial acoustic and financial benefits, but their durability and safety must be taken into account.

Satellite data from the Torres Islands in the southwest Pacific suggest that rising sea-levels in the region widely attributed to climate change is also partly caused by sinking of the islands following earthquakes in the 1990s, according to recent research.

Residents living within half a mile of unconventional natural gas wells may have an increased risk of illness from exposure to air pollution from the wells, according to a recent study. The peer-reviewed study recommends that risk prevention efforts to minimise impacts on human health should concentrate on communities living and working close to wells during well completions and that further studies on health effects of exposures to air emissions from such projects should be carried out.

Over 75 000 regulatory inspection reports for over 32 000 oil and gas production wells drilled in Pennsylvania, US between 2000 and 2012, have been analysed in a recent study. In these reports, the inspectors logged six times as many incidents of damage to the walls of shale gas and oil wells than in wells for conventional oil and gas.

Bee pollination improves the shape, weight and shelf-life of strawberries, contributing a staggering €1.05 billion to the European strawberry market per year, new research suggests. By blocking bees from a set of plants, the researchers demonstrated the substantial effects of bee pollination on the quality of the fruit.

Gendered expectations in marriage are not just bad for women, they are also bad for men, according to a new study by University of Connecticut (UConn) sociologists.

Airports are associated with air and noise pollution and may, therefore, reduce the quality of life of local people. This study assessed the link between aircraft noise and subjective wellbeing, using data from 17 English airports. The authors conclude that living under flight paths has a negative effect on people’s overall wellbeing, equivalent to around half of the effect of being a smoker for some indicators.

High levels of energy consumption and carbon emissions are not necessary for high standards of living, according to a new study. In recent decades, the same human needs have been met with ever decreasing energy and carbon levels, achieving a steady decoupling of human development from energy use and carbon emissions.

New research has investigated the possibility of transferring policy between EU Member States. It studied the outcomes of an EU-funded project that aimed to integrate land use planning and transport management across Europe, and identified barriers to transfer, which included language, differing planning traditions and difficulties in systematically adopting a policy across a nation. The study also highlights a role for EU projects in beginning the process of policy transfer.
