Berkeley Lab's ALS has received federal approval to begin construction on an upgrade that will boost the brightness of its X-ray beams at least a hundredfold. Scientists will use the improved beams for research into new materials, chemical reactions, and biological processes. This construction milestone enables the lab’s biggest project in three decades to move from planning to execution.

Researchers at the University of Chicago’s Pritzker School of Molecular Engineering (PME) have discovered a new material, MnBi6Te10, which can be used to create quantum highways along which electrons can move. These electron thoroughfares are potentially useful in connecting the internal components of powerful, energy-efficient quantum computers.

RUDN University researchers have shown that technogenic toxicants in the ecosystem are distributed unevenly. The reason for this is that they come from the source in “portions”. Further, an active interaction of technogenic and natural factors begins: soils temporarily deposit pollution and create conditions for the transformation of toxicants. Further, the buffer role of the roots is switched on, which do not allow some pollutants to pass through. From a practical point of view, these data are important for optimizing the traffic load in urban ecosystems and developing technologies for cleaning soils in the city.

Pumping up thermal water, separating lithium, and using it to produce batteries for electric mobility – the idea of lithium as an environmentally compatible and regionally available by-product of geothermal energy plants appears highly promising. However, it has not been clear so far whether domestic lithium extraction is really worthwhile.
