The Clarity Fuel Cell vehicle from Honda, which went on sale in March, is using platinum electrode catalysts from Tanaka Holdings in its fuel cells.

Electronic materials have been a major stumbling block for the advance of flexible electronics because existing materials do not function well after breaking and healing. A new electronic material created by an international team, however, can heal all its functions automatically even after breaking multiple times. This material could improve the durability of wearable electronics.

Sharks, skates, and rays can detect very weak electric fields produced by prey and other animals using an array of unusual organs known as the ampullae of Lorenzini. Exactly how these electrosensory organs work has remained a mystery, but a new study has revealed an important clue that may have implications for other fields of research.

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.

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.

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.

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.

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....

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.

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...
