Either before or after the removal of salt, the water often has to be treated to remove boron, which is toxic to plants, and heavy metals like arsenic and mercury, which are toxic to humans. Often, the process leaves behind a toxic brine that can be difficult to dispose of.

To Design Truly Compostable Plastic, Scientists Take Cues From Nature

Date Time To Design Truly Compostable Plastic, Scientists Take Cues From Nature Ivan Jayapurna, a UC Berkeley materials science and engineering graduate student, preparing a sample film of a new biodegradable plastic. (Credit: Adam Lau/UC Berkeley) Despite our efforts to sort and recycle, less than 9% of plastic gets recycled in the U.S., and most ends up in landfill or the environment. Biodegradable plastic bags and containers could help, but if they’re not properly sorted, they can contaminate otherwise recyclable #1 and #2 plastics. What’s worse, most biodegradable plastics take months to break down, and when they finally do, they form microplastics – tiny bits of plastic that can end up in oceans and animals’ bodies – including our own.

Unique X-Ray Instrument Reveals New Things About Lithium-Rich Battery Materials

Unique X-Ray Instrument Reveals New Things About Lithium-Rich Battery Materials Written by AZoMApr 12 2021 An international research group working at the Lawrence Berkeley National Laboratory (Berkeley Lab) of the U.S. Department of Energy (DOE) has gained a better understanding of lithium-rich battery materials with the help of a special X-ray instrument. Wanli Yang, a senior scientist at Berkeley Lab’s Advanced Light Source, working on a resonant inelastic X-ray scattering (RIXS) system. Yang adapted the RIXS technique for a recent Joule study on lithium-rich battery materials. Image Credit: Wanli Yang/Berkeley National Laboratory. Such materials have been the subject of intense studies for their ability to expand the operation of electronic devices and the range of electric vehicles.

X-ray study recasts role of battery material from cathode to catalyst

Yang adapted the RIXS technique for a recent Joule study. view more Credit: Berkeley Lab An international team working at the U.S. Department of Energy s Lawrence Berkeley National Laboratory (Berkeley Lab) used a unique X-ray instrument to learn new things about lithium-rich battery materials that have been the subject of much study for their potential to extend the range of electric vehicles and the operation of electronic devices. The researchers focused their investigations on a material called lithium manganese oxide (Li2MnO3), the extreme example of so-called lithium-rich materials, containing the largest amount of lithium possible within this family of materials. A recently developed tenet of the battery community is that battery electrodes composed of lithium-rich materials could offer high-voltage, high-capac
