Researchers at Idaho National Laboratory have discovered how to make 'superalloys' even more super, extending useful life by thousands of hours. The discovery could improve materials performance for electrical generators and nuclear reactors.
A catalyst for carbon dioxide recycling, Mineral pentlandite may also be a conceivable alternative to expensive precious metal catalysts. This is the result of a study conducted by researchers from Ruhr-Universität Bochum (RUB), Fritz-Haber Institute Berlin and Fraunhofer Umsicht in Oberhausen. Pentlandite had previously been known as a catalyst for hydrogen production. By adding a suitable solvent, the researchers successfully utilised it to convert carbon dioxide into carbon monoxide. The latter is a common source material in the chemical industry.
A team of researchers from Siberian Federal University (SFU) obtained thin copper/gold and iron/palladium films and studied the reactions that take place in them upon heating. Knowing these processes, scientists will be able to improve the properties of materials currently used in microelectronics. The article of the scientists was published in the Journal of Solid State Chemistry.
Nagoya University-led researchers have found an easier, scalable way to produce high-quality 2D sheets of germanium, possibly paving the way to industrial-scale production and the advent of the next generation of electronics.
Scientists from Tokyo University of Agriculture and Technology (TUAT), Japan, have discovered that a catalyst poison, which deactivates homogeneous catalysts, can be converted into an efficient ligand by introduction of a substituent. This indicates that the catalyst poison is not "Born This Way" but can be "Reborn" as an efficient ligand. This finding is of service to expand the ligand design in homogeneous catalysts.
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) in Germany have developed an electronic skin (e-skin) with magnetosensitive capabilities, sensitive enough to detect and digitize body motion in the Earth's magnetic field. As this e-skin is extremely thin and malleable, it can easily be affixed to human skin to create a bionic analog of a compass. This might not only help people with orientation issues, but also facilitate interaction with objects in virtual and augmented reality.
Hollow football-shaped carbon structures, called fullerenes, have applications in areas ranging from artificial photosynthesis and nonlinear optics, to the production of photoactive films and nanostructures. In a new study published in EPJ D, Kirill B. Agapev from ITMO University, St. Petersburg, Russia, and colleagues have developed a method that can be used for future simulations of fullerene complexes and thus help understand their characteristics.
Scientists at Tokyo Technology produced subnano-sized metallic particles that are very effective as catalysts for the oxidation of hydrocarbons. These catalysts can be as much as 50 times more effective than well-known Au-Pd bimetallic nanocatalysts.
Observing the behavior of the particles in the composite metals helps to understand the mechanism of losing its strength and ductility, which makes possible to design the composites metals with higher strength and ductility.
Fuel cells that work with the enzyme hydrogenase are, in principle, just as efficient as those that contain the expensive precious metal platinum as a catalyst. However, the enzymes need an aqueous environment, which makes it difficult for the starting material for the reaction -- hydrogen -- to reach the enzyme-loaded electrode. Researchers solved this problem by combining previously developed concepts for packaging the enzymes with gas diffusion electrode technology.
