Tests lead to doubling of fuel cell life
24-05-2013
Researchers working to improve durability in fuel cell powered buses, including a team from Simon Fraser University, have discovered links between electrode degradation processes and bus membrane durability. The team is quantifying the effects of electrode degradation stressors in the ...
Innovation could bring flexible solar cells, transistors, displays
24-05-2013
Researchers have created a new type of transparent electrode that might find uses in solar cells, flexible displays for computers and consumer electronics and future "optoelectronic" circuits for sensors and information processing. The electrode is made of silver nanowires covered with a ...
Detecting mirror molecules
New technique reliably tells left-handed from right-handed variant of a compound
24-05-2013
Harvard physicists have developed a novel technique that can detect molecular variants in chemical mixtures – greatly simplifying a process that is one of the most important, though time-consuming, processes in analytical chemistry. As described in a paper in Nature, post-doctoral researcher ...
Meeting the 'grand challenge' of a sustainable water supply
24-05-2013
Scientists and engineers must join together in a major new effort to educate the public and decision makers on a crisis in providing Earth's people with clean water that looms ahead in the 21st century. That's the focus of a comment article in the current edition of Chemical & Engineering ...
More emphasis needed on recycling and reuse of Li-ion batteries
24-05-2013
The discovery of potential environmental and human health effects from disposal of millions of rechargeable lithium-ion batteries each year has led scientists to recommend stronger government policies to encourage recovery, recycling and reuse of lithium-ion (Li-ion) battery materials. That's ...
Unique method creates correct mirror image of molecule
23-05-2013
Many molecules have a right and a left form, just like shoes. In pharmaceuticals, it is important that the correct form of the molecule is used. Researchers at the University of Gothenburg have been able to produce the one mirror image by using crystals with special properties. This can have ...
New method for producing clean hydrogen
23-05-2013
Duke University engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil fuels and their environmental implications. While hydrogen is ubiquitous in the environment, producing and collecting molecular hydrogen for ...
New molecular probes that shed light on biological systems
22-05-2013
Reactive sulfur species have attracted increasing attention in biomedical research because of their involvement in a variety of physiological functions. There has been a rising interest in sulfane sulfur compounds – compounds which contain sulfur atoms with six valence electrons, but no ...
Driving magnesium micromotors with seawater
22-05-2013
Scientists in the California have developed magnesium-based Janus micromotors that self-propel in seawater. Research shows how the micromotors can be used to capture and transport oil droplets from contaminated seawater, presenting a possible environmental application for the removal of oil ...
Moving liquid metal marbles
22-05-2013
Researchers in Australia have found a new method to induce the controlled movement of liquid metal droplets in aqueous environments, by coating them in nanoparticles to form ‘liquid metal marbles.’ Research shows that coating droplets of liquid metal galinstan with WO3 nanoparticles increases ...
