Human activity in the Industrial Age – approximately the last 150 years – has significantly increased atmospheric levels of methyl bromide, a gas known for harming the ozone layer in the Earth’s stratosphere.
A research team led by UC Irvine scientist Eric Saltzman reached this conclusion after examining an ice core recovered from Antarctica. By studying air bubbles trapped in the core, Saltzman’s team was able to compare levels of methyl bromide in the atmosphere over the last three centuries. The team concluded that during the industrial era, the amount of global atmospheric methyl bromide in Southern Hemisphere air appears to have increased by 3.5 parts per trillion, or approximately 50 percent of the preindustrial level of the gas.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
