Photoelectrochemical (PEC) water splitting for hydrogen fuel generation has been considered the Holy Grail of electrochemistry. But to achieve it, many scientists believe the materials have to be abundant and low cost. The most promising oxide photocathodes are cuprous oxide (Cu2O) ...
For years, a new synthesis method has been developed at TU Wien (Vienna) to unlock the secrets of "strange metals". Now a breakthrough has been achieved. Superconductors allow electrical current to flow without any resistance - but only below a certain critical temperature. Many materials have to ...
Replacing the volatile and flammable liquid or polymer electrolytes now used in lithium-ion batteries with inorganic solid-state lithium-ionic ceramic conductors could significantly improve both safety and performance of the cells. Solid-state conductors would allow for novel cathode and anode ...
Azopolymer material allows light-assisted imprinting of nanostructures for structurally colored surfaces
Structural colors appear because the imprinted pattern on a surface changes the wavelengths of light. Chinese scientists have introduced an azopolymer that allows the imprinting of nanopatterns in a novel room-temperature lithographic process. A key aspect of the technique is the light-induced ...
Complex, porous, chiral nano-patterns arise from a simple linear building blocks
Nanoscience can arrange minute molecular entities into nanometric patterns in an orderly manner using self-assembly protocols. Scientists at the Technical University of Munich (TUM) have functionalized a simple rod-like building block with hydroxamic acids at both ends. They form molecular ...
Inexpensive, durable and more environmentally friendly
Throughout history, people have sought vibrant blue pigments. The Egyptians and Babylonians used lapis lazuli 6,000 years ago. In 1802, a French chemist synthesized cobalt blue. More recently, in 2009 scientists discovered YInMn Blue, otherwise known as "Oregon Blue." But most of these pigments ...
Cement and concrete haven't changed much as technology in over a hundred years, but researchers in Colorado are revolutionizing building materials by literally bringing them to life. The method developed, presented January 15 in the journal Matter, combines sand and bacteria to build a living ...
BASF plans to increase the production capacity for its antioxidant Irganox® 1520L by 20% at the site in Pontecchio Marconi, Italy. Irganox® 1520L is a key product in BASF’s antioxidant portfolio. With this expansion, BASF responds to an increasing market demand and aims to better serve its global ...
Scientists find overabundance of intentional defects can cause battery cathodes to fail
Intentional defects in batteries have given Rice University scientists a window into the hazards of pushing lithium-ion cells too far. New simulations by Rice materials scientist Ming Tang and graduate student Kaiqi Yang, detailed in the Journal of Materials Chemistry A, shows too much stress in ...
Innovative process to rapidly dissolve plant fibers
Researchers have developed a new process that could make it much cheaper to produce biofuels such as ethanol from plant waste and reduce reliance on fossil fuels. Their approach, featuring an ammonia-salt based solvent that rapidly turns plant fibers into sugars needed to make ethanol, works well ...
