Today's Tech News: Notable or Not?

https://www.eurekalert.org/news-releases/1121686 "utilizing lead halide perovskites highly efficient but toxic/ degrade quickly when exposed to moisture/ heat, but substituting non-toxic cesium manganese bromide has low light-emission efficiency... overcome introducing europium(III) energy-transfer pathway boosting light output: 3.37X higher quantum yield... quantum dots embedded within borosilicate glass protecting from water/ oxygen, retained 97% light intensity after stored in water >450 days... anti-counterfeiting QR codes, high-durability red/ white LEDs"

https://www.eurekalert.org/news-releases/1106159 "growing the sodium niobate on substrate induces 3 different phases (atom arrangements) simultaneously at room temperature (as film's atoms contract/ expand to match the substrate's atomic structure) without traditional methods like changing temperature/ chemical composition... optimizes ferroelectric properties by creating more boundaries between phases... even slight changes in length led to substantial phase changes... future: investigate the effect of strain at extreme temperatures ranging from -270° to 1,000°C"
