Berkeley Lab Researchers Receive Awards for Cooling Efficiency Work

Two researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) have been recognized by the Kigali Cooling Efficiency Program (K-CEP). The awards for Nihar Shah and Won Young Park honor their work on improving the energy efficiency of cooling systems and evaluating the benefits of those improvements.

Material Discovery Makes Lithium-Sulfur Batteries More Sustainable

Prominent battery research has made great strides in advancing next-generation rechargeable batteries, which might use lithium-sulfur (Li-S) batteries, rather than the traditional Li-ion batteries commonly found in electric cars and mobile phones.

The graphs show PM2.5 concentrations (microgram per cubic meter), with the x-axis as measured by the regulatory monitor in downtown Berkeley and the y-axis as measured by PurpleAir monitors. On the good air day, the numbers were roughly the same. However, when wildfire smoke was present the PurpleAir readings were consistently far higher than the regulatory monitor’s.

Low-Cost Home Air Quality Monitors Prove Useful for Wildfire Smoke

Over the last few years of frequent and intense wildfire seasons, many parts of the U.S. have experienced hazardous air quality for days on end. At the same time a number of low-cost air quality monitors have come on the market, allowing consumers to check the pollutant levels in their own homes and neighborhoods. So, air quality scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) wanted to know: are these low-cost monitors any good?

The answer is: yes – to a degree.
