Journal ArticleDOI

Methyl arsenic adsorption and desorption behavior on iron oxides.

TL;DR: Increased methyl substitution resulted in both decreased adsorbed arsenic at low arsenic concentrations in solution and increased ease of arsenic release from the iron oxide surface.
Journal ArticleDOI

Arsenite oxidation by a poorly crystalline manganese-oxide. 2. Results from X-ray absorption spectroscopy and X-ray diffraction.

TL;DR: X-ray absorption spectroscopy and X-ray diffraction data show that Mn(II) sorption on a poorly crystalline hexagonal birnessite (δ-MnO₂) is important in passivation early during reaction with As(III).
Journal ArticleDOI

Arsenite oxidation by a poorly crystalline manganese-oxide 1. Stirred-flow experiments.

TL;DR: It is indicated that As(III) oxidation by poorly crystalline δ-MnO₂ involves several simultaneous reactions and reinforces the importance of studying reaction mechanisms over time.
Journal ArticleDOI

Evaluation of individual and ensemble probabilistic forecasts of COVID-19 mortality in the United States

Estee Y Cramer, +294 more
TL;DR: In this paper , the authors compared the probabilistic accuracy of short-term forecasts of reported deaths due to COVID-19 during the first year and a half of the pandemic in the United States.
Journal ArticleDOI

Arsenite oxidation by a poorly-crystalline manganese oxide. 3. Arsenic and manganese desorption.

TL;DR: Desorption of As(V) and As(III) from a poorly crystalline phyllomanganate (δ-MnO(2)) by two environmentally significant ions is investigated using a stirred-flow technique and X-ray absorption spectroscopy (XAS).
