A new system for synthesizing quantum dots across the entire spectrum of visible light drastically reduces manufacturing costs, can be tuned on demand to any color and allows for real-time process monitoring to ensure quality control.
In a paper to be published in the forthcoming issue in NANO, researchers from China have proposed a way to reduce uranium concentration in contaminated water. As an essential nuclear fuel, uranium has been greatly used an inevitably released to the environment. Without proper disposal, exposure to uranium can result in serious harms to the ecology and health of humans.
In a paper to be published in the forthcoming issue in NANO, researchers from the China University of Petroleum (East China) have summarized the recent advances in application of 2D nanomaterials on the electrode materials of lithium-ion batteries, owing to their compelling electrochemical and mechanical properties that make them good candidates as electrodes in lit-ion batteries for high capacity and long cycle life.
At relatively balmy temperatures, heat behaves like sound when moving through graphite, study reports.
While it's not a case of reinventing the wheel, researchers are looking at ways to improve standard braking equipment on trains and cars. By mixing carbon fibers into polymer-based brakes, a group of researchers at UBC Okanagan, Sharif University of Technology in Iran and the University of Toronto were able to design brakes that are self-lubricating.
Researchers have examined a method to extract rare-earth elements from mining waste that could provide the world with a reliable supply of the valuable materials. The research, led by Idaho National Laboratory and Rutgers University with support from the Critical Materials Institute, is online and in an upcoming issue of the Journal of Chemical Thermodynamics.
Cleaning pollutants from water with a defective filter sounds like a non-starter, but a recent study by chemical engineers at Rice University found that the right-sized defects helped a molecular sieve soak up more perfluorooctanesulfonic acid (PFOS) in less time.
The Purdue team created wearable technology to convert mechanical energy into electrical energy. The Purdue team invented a liquid-metal-inclusion based triboelectric nanogenerator, called LMI-TENG.
Scientists at Tokyo Tech and Okayama University found a way of greatly improving the performance of LiCoO2 cathodes in Li-ion batteries by decorating them with BaTiO3 nanodots. Most importantly, they elucidated the mechanism behind the measured results, concluding that the BaTiO3 nanodots create a special interface through which Li ions can circulate easily, even at very high charge/discharge rates.
Discovery comes as an extension of the development of a polymer ion-gel, which promises to outperform conventional flammable liquid battery electrolytes.
