Matthew P Stewart
Molecular ionization potentials (IP) and photoionization cross sections (σ) can affect the sensitivity of photoionization detectors (PIDs) and other sensors for gaseous species. This study employs several methods of machine learning (ML) t...
Siderophore-Mediated Mobilization of Manganese Limits Iron Solubility in Mixed Mineral Systems [0.03%]
siderophore介导的锰动员限制混合矿物体系中铁的溶解性
Kyounglim Kang,Jasquelin Peña
Kyounglim Kang
Recent laboratory and field studies show the need to consider the formation of aqueous Mn(III)-siderophore complexes in manganese (Mn) and iron (Fe) geochemical cycling, a shift from the historical view that aqueous Mn(III) species are unst...

Using publicly available data from the National Air Pollution Surveillance Program, water-soluble ion mole fractions in PM2.5 and PM2.5-10 were extracted for 2010, 2012, 2013, and 2015 at six locations across Canada. Fine particle ion conte...
Floating Liquid Droplets on the Surface of Cryogenic Liquids: Implications for Titan Rain [0.03%]
低温液体表面的悬浮液滴：对土卫六降雨的影响
Kendra K Farnsworth,Alejandro Soto,Vincent F Chevrier et al.
Kendra K Farnsworth et al.
Saturn's moon, Titan, has a hydrocarbon-based hydrologic cycle with methane and ethane rainfall. Because of Titan's low gravity, "floating liquid droplets" (coherent droplets of liquid hydrocarbons that float upon a liquid surface) may form...
Model Atmospheric Aerosols Convert to Vesicles upon Entry into Aqueous Solution [0.03%]
模拟大气气溶胶在进入水溶液后转化为小泡
Serge Nader,Alexandre Baccouche,Fiona Connolly et al.
Serge Nader et al.
Aerosols are abundant on the Earth and likely played a role in prebiotic chemistry. Aerosol particles coagulate, divide, and sample a wide variety of conditions conducive to synthesis. While much work has centered on the generation of aeros...
