Equation to end bond order contention

A researcher in the US has proposed a new way of computing bond order, which he says is more general and more consistently accurate across diverse kinds of materials.

Computed bond orders in red, sum of bond orders in blue, and net atomic charges in black for two hexafluorides

Source: © Royal Society of Chemistry SF6 contains six single-order S–F bonds and confirms that SF6transcends the Lewis octet rule that predicts four rather than six shared electron pairs around the central sulfur atom. The Db–F bond order (0.75) is lower than the S–F bond order (0.95)

Bond order quantifies how many electrons two atoms in a material share. But it’s a theoretical concept, not something you observe experimentally, so defining it and calculating it can get a bit fuzzy. ‘Some new chemistry students find it difficult to memorise which rules apply to which chemicals. For example, why should N2 and CF4 be described by a Lewis structure while triplet O2 and SF6are not?’ says Thomas Manz of New Mexico State University. ‘My method introduces a unifying principle where you no longer have to memorise different rules for different materials. All you have to do is calculate and you will get the accurate bond order,’ he explains.

Tomography keeps its cool to analyse ice cream

Source: © Royal Society of Chemistry This 3D rendered image shows a central air cell bounded by faceted ice crystals. Scale bar is 100mm

Researchers from the UK have developed a new 3D x-ray tomography (XRT) method to visualise the effects of changing temperature on the microstructure of ice cream.

Ice cream is a mixture of milk, fats, sugars, proteins, emulsifiers, stabilisers and flavours that are aerated and then frozen to form a soft solid comprising about 30% ice, 50% air, and 5–15% fat droplets suspended in a sugar solution. Its quality depends on the size of its ice crystals and air bubbles: smaller crystals and bubbles make it smoother and creamier. And since this complex colloid is unstable above –30˚C, its microstructure will change during shipping and storage (domestic freezers are usually at around –18˚C), which will affect its taste and texture.

Giridhar Madras has been a Full Professor in the Chemical Engineering Department at the Indian Institute of Science, India since 2007 and has published more than 450 international journal articles, which have more than 13000 citations and is among the most cited engineering scientists in India with a h-index of 55. His research interests are in the area of reaction engineering applied to polymers, supercritical fluids, and catalysis.


Heloise Pastore
is currently a Full Professor at the Chemistry Institute of the State University of Campinas in Brazil and has research interests and experience in Molecular sieves, isomorphic substitution, zeolites, mcm-41 and supramolecular arrangements.

Professor Pastore is responsible for the invention of two new families of molecular sieves called CAL and UEC.

 

Manuel Minas da Piedade‘s research interests are mainly focused on the energetics of molecules (e.g. fullerenes, PAHs, ionic liquids), crystals (nucleation, polymorphism, crystal engineering), and, very recently, also living cells. He is currently based at the Faculty of Sciences, University of Lisbon, Portugal as an Associate Professor of Chemistry and Biochemistry.

Sandpaper electrode harvests electricity from friction

Researchers in South Korea have developed a method to turn common sandpaper into an electrode that generates current from friction, promising a way to power portable devices with ambient mechanical energy.

Source: © iStock Sandpaper already has the rough texture required to make an effective triboelectric generator

Wirelessly powering small devices by harvesting energy from the environment could eliminate the need to ever recharge them. This is especially useful for embedded sensors as they will often be located in inaccessible places without a power supply, for example, on the inside of machines or the side of buildings.

Cystic fibrosis treatment clears the way

Stabilising a mucus attacking enzyme with cross-links could allow it to be delivered orally to fight infections in cystic fibrosis patients.

Pseudomonas aeruginosa is one of the commonest opportunistic pathogens in cystic fibrosis. The bacterium produces alginate, a polysaccharide which causes significant mucus build-up in the lungs and intestine. In addition to affecting patients’ quality of life, this also significantly obstructs the delivery of antibiotics, requiring increased dosages which can lead to antibiotic resistance and an increased chance of side-effects.

Guillermo Castro at the National University of La Plata in Argentina, and his team, investigate the delivery of drugs with significant administrative problems’…
