Tiny microbots can clean up water
IBEC researchers have developed a self-propelled tiny ‘microbot’ that can remove lead from contaminated water. Working with colleagues in Stuttgart and Singapore, Samuel Sánchez’s group used graphene oxide to make their microscale motors, which are able to adsorb lead from industrial wastewater from a level of 1000 parts-per-billion to down to below 50 parts-per-billion in just an hour.
Fine tuning phosphorous heterocycle materials for organic electronics
Scientists at Tokyo Institute of Technology have produced airstable 1-aryl 1,3-diphosphacyclobutane-2,4-diyl materials by direct arylation with electron rich aromatic substituents. This method enables the fine tuning of the electronic properties of such phosphorous heterocycles compounds for applications including fabrication of organic electronics and hydrogen fluoride sensors.
Cactus 'skin' boost performances of fuel cells
Inspired by the humble cactus, a type of membrane has the potential to significantly boost the performance of fuel cells and transform the electric vehicle industry.The membrane, developed by scientists from CSIRO and Hanyang University in Korea, was described in the journal Nature. The paper shows that in hot conditions the membrane, which features a water repellent skin, can improve the efficiency of fuel cells by a factor of four.
Breakthrough on safer & smarter batteries
For anyone who’s ever panicked when their mobile device chirped, “low battery", the future could be far less stressful, thanks to the advanced battery research of scientists at the Toyota Research Institute of North America (TRINA). A breakthrough involving magnesium batteries may soon open the doors for smaller, longer-lasting batteries for everything from cars to cell phones.
Welding wires are copper-free
ESAB Welding & Cutting Products introduces PrimeWeld, a series of copper-free, seamless flux-cored welding wires specifically designed to meet the needs of the offshore construction industry. Produced using a unique seamless manufacturing process, PrimeWeld offers a very low diffusible hydrogen level which minimises the risk of hydrogen-induced cold cracking (HICC) when welding thicker components, especially critical in offshore applications....
Measuring solvent vapour permeability
Water and other vapours can permeate through the actual fabric of adhesives or mastics, sometimes in large volume. This can cause a huge variety of adhesion problems, including failure – water and its vapour are now thought to be the world’s most damaging contaminant.
Discovery may indicate possible revolutionary antibiotics
An international team including the Lomonosov Moscow State University researchers have determined which enzyme enables Escherichia coli bacterium (E. coli) to breathe. The study is published in the Scientific Reports. Scientists discovered how the E. coli bacterium can survive in the human gut, resolving the mystery of how they breathe. Vitaliy Borisov, senior researcher, explains that E. coli uses special enzymes that are absent in the human bod...
JENSA system will take physicists to infinity and beyond
Physicists studying stellar explosions, the origin of life and just about everything in between could gain light years in precision because of a system inspired by a team led by Kelly Chipps of the Department of Energy's Oak Ridge National Laboratory. As the sophistication of radioactive ion beam facilities around the world increases, there is pressure to ensure that the targets and detectors necessary to perform experiments maintain the pace.
Silicone rubber seals from SFS cut corrosion in LED luminaires
Materials commonly used for seals and gaskets are vulcanised elastomers such as ethylene propylene (EPDM) and nitrile butadiene rubber (NBR). However, as they contain sulphur they can leach out hydrogen sulphide over time which can cause corrosion if they are used in LED light fittings. For this reason The SFS Manufacturing Group are now offering silicone rubber components that are guaranteed 100% sulphur free and made from compounds specifically...
Method uses electricity for better achieving chemical reactions
Scientists at The Scripps Research Institute (TSRI) have found a better way to achieve a chemical reaction that is used widely in the pharmaceutical as well as flavour and fragrance industries. Traditional methods of "allylic oxidation" typically employ toxic and/or expensive reagents such as chromium, ruthenium or selenium. That largely prevents the reaction from being used at industrial scales, for example to manufacture pharmaceuticals.
