Reversible Reaction

USTC's Prof. Chen Wei leads a breakthrough in energy storage—a resilient, all-weather hydrogen-chlorine battery, achieving remarkable stability and efficiency across extreme temperatures.

In this first-of-its-kind battery, a benzoquinone-based negative electrode is used alongside a solid Nafion polymer electrolyte. Metals traditionally serve as the active materials for the negative electrodes in batteries. However, there's been a shift towards using redox-active organic molecules li

Aluminum-ion batteries are seen as a promising alternative to conventional batteries that use scarce and difficult-to-recycle raw materials such as lithium. This is because aluminum is one of the most common elements in the Earth's crust, is easier to recycle and is also safer and less expensive than lithium. However, the development of such aluminum-ion batteries is still in its infancy, as suitable electrode…

A group of scientists from Durham University and University of York have twisted molecules to their breaking point in order to challenge the understanding of chemical bonds.

Recent lab studies have shown that aging is a reversible process, an advancement that has prompted scientists to seek ways to stop the functional decline of cells and tissues, as well as restore their regenerative capacity.

An invention from UConn researcher Al Kasani makes camping in hot weather a breeze.

Old, blind mice have regained their eyesight, developed smarter, younger brains and built healthier muscle and kidney tissue in lab experiments.

There is an ever-present struggle to reduce carbon-based energy sources and replace them with low or no-carbon alternatives. The process of splitting water could be the resolution.

Hydrogen spillover is exactly what it sounds like. Small metal nanoparticles anchored on a thermally stable oxide, like silica, comprise a major class of catalysts, which are substances used to accelerate chemical reactions without being consumed themselves. The catalytic reaction usually occurs on the reactive—and expensive—metal, but on some catalysts, hydrogen atom-like equivalents literally spill from the metal…

Einstein's most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.

In Massachusetts, a team of researchers at MIT says they may have found the key to a truly efficient and inexpensive removal mechanism to remove CO2 from seawater. The findings were reported recently in the journal Energy and Environmental Science. The existing methods for removing carbon dioxide from seawater apply a voltage across a stack […]

Sodium is cheap and plentiful, but its use in batteries brings some challenges.

CU Boulder scientists have successfully synthesized graphyne, which has been theorized for decades but never successfully produced.

By learning more about how metalloprotein enzymes work, MIT chemist Dan Suess hopes to eventually devise new ways to perform fundamental chemical reactions that could be used to capture carbon from the atmosphere or to produce fossil fuel alternatives.

MIT chemical engineers devised an efficient way to convert carbon dioxide to carbon monoxide, which can be used to generate useful compounds such as ethanol and other fuels.

A team of Chinese researchers is proposing a novel design for calcium-oxygen (Ca-O2) batteries with higher efficiency, a technology that could one day replace lithium-ion batteries, bringing...

According to a study published in Advanced Functional Materials, a research team led by Prof. Hu Linhua from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences found that adding disodium maleate (DMA) to the electrolyte of aqueous zinc-ion batteries would lead to the growth of the preferred Zn (002) texture, which could effectively inhibit the growth of zinc (Zn) dendrite and improve the…

Materials scientists aim to develop autonomous materials that function beyond stimulus responsive actuation. In a new report in Science Advances, Yang Yang and a research team in the Center for Bioinspired Energy Science at the Northwestern University, U.S., developed photo- and electro-activated hydrogels to capture and deliver cargo and avoid obstacles on return.

Many molecules assemble into crystalline or disordered glassy structures on surface. With certain assembly approaches, specific molecules can be made to form ordered yet aperiodic structures, such as fractals and quasicrystals. Sierpiński triangles (STs) have been prepared on surfaces and in solutions through halogen bonding, metal-organic coordination, hydrogen bonding, and covalent bonding interactions.
