A simple potassium solution could boost the efficiency of next-generation solar cells, by enabling them to convert more sunlight into electricity.
An international team of researchers led by the University of Cambridge found that the addition of potassium iodide 'healed' the defects and imm ... more
A polymer mat developed at Rice University has the ability to fish biologically harmful contaminants from water through a strategy known as "bait, hook and destroy."
Tests with wastewater showed the mat can efficiently remove targeted pollutants, in this case a pair of biologically harmful ... more
Hydrogen holds promise as an inexpensive form of clean energy, but finding an efficient and affordable way to produce the fuel from water - a technique known as water-splitting - remains a key scientific challenge.
A researcher from the University of Houston is working with a colleague in T ... more
Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make "sequential" polymers, using visible light to change how different building blocks are combined into polymer chains. By simply switching the light on or off, they were able to realize di ... more
For years, scientists have been inspired by nature to innovate solutions to tricky problems, even oil spills -- manmade disasters with devastating environmental and economic consequences. A new USC study takes a cue from leaf structure to fabricate material that can separate oil and water, ... more
AkzoNobel Specialty Chemicals is partnering with three groups in Sweden to explore the opportunities for producing green hydrogen and 'electrofuels' using renewable electricity. The partners are RISE Research Institutes of Sweden (RISE), forestry group Södra and packaging materials company ... more
In a new study, researchers from the U.S. Department of Energy's (DOE) Argonne and Brookhaven National Laboratories observed the formation of two kinds of defects in individual nanowires, which are smaller in diameter than a human hair.
These nanowires, made of indium gallium arsenide, coul ... more
Chemists advance sustainable battery technology
Utah State University chemists' efforts to develop alternative battery technology solutions are advancing.
Tianbiao Liu, assistant professor in USU's Department of Chemistry and Biochemistry, and his team reported a new molecular design for aqueous organic redox flow batteries, known as AOR ... more
Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds of other devices. Now a group of physicists has found a material ... more
Cephalopods -- which include octopuses, squid, and cuttlefish -- are masters of disguise. They can camouflage to precisely match their surroundings in a matter of seconds, and no scientist has quite been able to replicate the spectacle. But new research by Leila Deravi, assistant professor ... more
