Researchers from Queen Mary University of London have developed new thermoelectric materials, which could provide a low-cost option for converting heat energy into electricity.
Materials known as halide perovskites have been proposed as affordable alternatives to existing thermoelectric materials, however so...
Hypersaline brines—water that contains high concentrations of dissolved salts and whose saline levels are higher than ocean water—are a growing environmental concern around the world. Very challenging and costly to treat, they result from water produced during oil and...
In the blockbuster Terminator movie franchise, an evil robot morphs into different human forms and objects and oozes through narrow openings, thanks to its "liquid-metal" composition. Although current robots don't have these capabilities, the technology is getting closer with the development...
6DNM-amine is a proof of concept that the new approach can transform gram-positive antibiotics to drugs that can also kill gram-negative microbes.

Scientists report that they now know how to build a molecular Trojan horse...
Since element 99 -- einsteinium -- was discovered in 1952 at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it...
A molecule of ammonia, NH3, typically exists as an umbrella shape, with three hydrogen atoms fanned out in a nonplanar arrangement around a central nitrogen atom. This umbrella structure is very stable and would normally be expected to require...
Pharmaceuticals owe their effects mostly to their chemical composition, but the packaging of these drugs into specific physical formulations also need to be done to exact specifications. For example, many drugs are encapsulated in solid microparticles, the size and...
Using surface-enhanced Raman spectroscopy, Columbia Engineers are first to observe how CO2 is activated at the electrode-electrolyte interface; their finding shifts the catalyst design from trial-and-error paradigm to a rational approach and could lead to alternative, cheaper, and safer...
A touch of gold—or another noble metal—can change the structure of a crystal and its intrinsic properties, physicists at the University of Warwick have demonstrated in a display of modern-day alchemy.
Scientists at the University of Warwick have found a...
Life on Earth arose about 4 billion years ago when the first cells formed within a primordial soup of complex, carbon-rich chemical compounds.
These cells faced a chemical conundrum. They needed particular ions from the soup in order to perform...
Vaccines are notoriously difficult to transport to remote or dangerous places, as they spoil when not refrigerated. Formulations are safe between 2°C and 8°C, but at other temperatures the proteins start to unravel, making the vaccines ineffective. As a...
