TL;DR: The qualitatively similar concentration dependence observed for survival under 254 nm of radiation, in contrast with the lower resistance of denser colonies to 20 kHz power ultrasound and the delayed onset of extracellular beta-D-galactosidase activity in bacterial populations already decimated by EHDs, support the view that UV radiation is the dominant disinfection agent generated by electrohydraulic discharges.

TL;DR: Fog samplers of five different designs were operated simultaneously to assess differences, if any, in measured acidity, analyte concentrations, and liquid water collection efficiencies.

TL;DR: This work reports the simultaneous detection, by online thermospray ionization mass spectrometry, of cysteine sulfenate (CySO(-)) and the overoxidized cystein sulfinate and CySO(2)(-)) species on the surface of aqueous CyS microdroplets exposed to O(3)(g) for <1 ms.

TL;DR: In this article, measurements of inorganic aerosol and gas phase species are presented for three sites in central California during a 4-day period in April 1988, where the measurement sites were located along an east-west transect at Visalia, Ash Mountain, and Lower Kaweah.

TL;DR: Guzman et al. as mentioned in this paper showed that pyruvic acid (PA, an ubiquitous ice contaminant) can lead to the same products nearly as efficiently in both media as water and ice.
