Ultrasound test echos with battery charge

Measuring the charge within a battery can often involve the use of expensive equipment such as synchrotron light sources, which are not accessible to all researchers. However, scientists at Princeton University lead by Dr Daniel Steingart have developed a method of using ultrasound echoes to measure charge within a battery at different times, giving physical insight into a battery’s state. This ultrasomic imaging of what is happening inside a cell could prove to be useful commercially.

Nanoporous methane storage – an impossible target?

Emma Stephen writes about an EES article in Chemistry World.


Is it possible to design a material to fulfil current methane storage goals? This is the question that a multi-disciplinary research team set out to answer by rapidly screening hundreds of thousands of possible methane storage materials in a computational study. Methane could reduce global dependence on oil so the search is on for nanoporous materials to act as fuel tanks for this tricky-to-store gas; but things are not looking promising.

Biodiesel byproduct rejuvenated into plastic feedstock

Chemistry World article written by Geri Kitley

A significant amount of glycerol (bottom layer) is leftover when making biodiesel (top layer) © Bo Cheng/ETH Zurich

A sustainable method to synthesise platform chemical lactic acid from waste glycerol, a byproduct of biodiesel production, has emerged from research in Switzerland.

Collaboration between the advanced catalysis engineering and the safety and environmental technology groups at the Swiss Federal Institute of Technology (ETH) in Zurich, headed by Javier Pérez-Ramírez and Konrad Hungerbuehler, respectively, gave way to the new cascade process. Glycerol is first oxidised to give dihydroxyacetone through an established enzymatic process. Dihydroxyacetone is then isomerised over a tin-containing zeolite catalyst, which was designed by ETH Zurich team, to give lactic acid.
