Journal ArticleDOI
Control of solute concentrations in cloud and fog water by liquid water content
TL;DR: In this paper, the authors measured the concentrations of Cl−, NO_3−, and SO_4^(2−) in atmospheric cloudwater collected with a passive collector from a remote marine site and observed an inverse relationship between the measured ion concentrations and the liquid water content of the clouds.
Journal ArticleDOI
Impact of alternative metrics on estimates of extent of occurrence for extinction risk assessment
Lucas Joppa,Stuart H. M. Butchart,Michael R. Hoffmann,Michael R. Hoffmann,Steve P. Bachman,Steve P. Bachman,H. Resit Akçakaya,Justin Moat,Justin Moat,Monika Böhm,Robert A. Holland,Adrian C. Newton,Beth Polidoro,Adrian Hughes +13 more
TL;DR: The results suggest that uniformly applying the MCP approach may lead to a one-time down listing of hundreds of species but ultimately ensure consistency across assessments and realign the calculation of EOO with the theoretical basis on which the metric was founded.
Journal ArticleDOI
Sonochemical Degradation Rates of Volatile Solutes
TL;DR: In this paper, degradation rates of chlorinated methanes, ethanes, and ethenes in water solutions sonicated at f = 205, 358, 618, and 1078 kHz were reported.
Journal ArticleDOI
Enhancing the activity of oxygen-evolution and chlorine-evolution electrocatalysts by atomic layer deposition of TiO2.
Cody E. Finke,Stefan T. Omelchenko,Justin T. Jasper,Michael F. Lichterman,Carlos G. Read,Nathan S. Lewis,Michael R. Hoffmann +6 more
TL;DR: Electrocatalysts exposed to ~3–30 ALD cycles of TiO2 exhibited overpotentials at 10 mA cm–2 of geometric current density that were several hundred millivolts lower than uncoated catalysts, with correspondingly higher specific activities, indicating a correlation between oxidation state, potential of zero charge, and activity of the tuned electrocatalyst.
Journal ArticleDOI
Thermal relaxation of lithium dendrites
Asghar Aryanfar,Daniel J. Brooks,Agustín J. Colussi,Boris V. Merinov,William A. Goddard,Michael R. Hoffmann +5 more
TL;DR: A key role for the mobility of interfacial Li-atoms is suggested in determining the morphology of dendrites at temperatures above the onset of surface reconstruction: TSR ≈ 0.65 TMB (TMB = 453 K: the melting point of bulk Li(0)).
