Our frequency-domain hyperspectral SRS microscope extends spectral coverage below 400 cm-1. Additionally, our graphic has been selected for the journal's supplementary cover. Congratulations to Matt Clark and his co-workers. The link: https://t.co/9ZWWikXYEd

[Alexander Laskin Group @alaskinlab]

Our paper detailing the quantification of particle-gas evaporation and the viscosity of organic aerosols has been published. This work introduces a novel measurement approach for studying aerosol chemistry. https://t.co/1wjIBkAAWp

[Alexander Laskin Group @alaskinlab]

Diego’s work on the darkening of biomass burning aerosol by evaporation is published. These findings provide new phenomenological insights for atmospheric models. @PurdueChemistry @WeizmannScience @EnvSciTech @AnfacPurdue https://t.co/RXlIk6H61k
