As(III, V) Uptake from Nanostructured Iron Oxides and Oxyhydroxides: The Complex Interplay between Sorbent Surface Chemistry and Arsenic Equilibria
Marco Sanna Angotzi,Valentina Mameli,Alessandra Fantasia,Claudio Cara,Fausto Secci,Stefano Enzo,Marianna Gerina,Carla Cannas +7 more
TL;DR: In this paper , the same experimental conditions for the batch tests permitted a direct comparison among the sorbents, particularly between the oxyhydroxides, known to be among the most promising As-removers but hardly compared in the literature.

Size- and Shape-Controlled Magnetic (Cr, Mn, Fe, Co, Ni) Oxide Nanocrystals via a Simple and General Approach
TL;DR: In this article, a reproducible and simple strategy using generic chemicals is introduced for controlling the size, shape, and size distribution of oxide nanocrystals, which is based on pyrolysis of metal fatty acid salts, the most common metal compounds compatible with nonaqueous solutions.

Profile shape functions in Rietveld refinements
R. A. Young,D. B. Wiles +1 more
TL;DR: In this paper, the authors compared the performance of six profile functions, including the pseudo-Voigt and Pearson VII, in Rietveld refinements with fixed-angle or fixed-wavelength powder diffraction data, obtained with neutrons or with X-rays.
