To help you stay up-to-date with the latest achievements from the chemical engineering research community here is our monthly instalment with some of the latest stories.
September’s five stories of amazing chemical engineering research and innovation are:
The Popeye effect – powered by spinach
Popeye was right; we can be powered by spinach! Researchers from the Technion-Israel Institute of Technology have developed a bio-photo-electro-chemical (BPEC) cell that produces electricity and hydrogen from water using sunlight, using a simple membrane extract from spinach leaves. The article, publish in the journal Nature Communications, demonstrates the unique combination of a man-made BPEC cell and plant membranes, which absorb sunlight and convert it into a flow of electrons highly efficiently. The team hope that this paves the way for the development of new technologies for the creation of clean fuels from renewable sources. The raw material of the device is water, and its products are electric current, hydrogen and oxygen.
Lithium ion batteries are used in a wide range of applications and technologies. As it happens; if you are reading my blog on a smartphone, laptop or tablet, you are probably holding one right now. From mobile phones to electric cars, Li-ion batteries are all around us, but how do we make sure they are safe?
As I have remarked previously in my blog ‘Bulletproof batteries‘, there are significant safety issues associated with Li-ion batteries. In 2013, a problem with overheating batteries forced airlines to ground their Boeing 787 ‘Dreamliner’ aircraft, after reports of batteries bursting into flames.
The use of Li-ion batteries is becoming more wide-spread. So we need to gain a better understanding of the hazards and risks associated with their use.
A team of chemical engineering researchers have discovered a breakthrough in catalytic converter research through perseverance. This research will help manufactures of cars reduce the need for the use of expensive platinum in catalytic converters.
Eric Peterson, a graduate student in Nanoscience and Microsystems Engineering at the University of New Mexico, began this discovery when he refused to accept that the measurements he recorded using x-ray absorption spectroscopy (XAS) were incorrect.
Professor of chemical and biological engineering, Abhaya Datye, worked with Eric on this project to improve our ability to measure the sizes of nanoparticles, focusing on those smaller than one nanometre (one billionth of a metre).
