Steels with good machinability are required for the ever-increasing demand for machining efficiency in industry. The manganese sulfide (MnS) inclusions in lead-free resulfurized free-cutting steels act as stress raisers, lowering the shear strength of steel such that the cutting resistance is re...detailed
Photocatalytic hydrogen production from hydrogen sulfide (H2S) splitting has been considered as an appealing and sustainable approach to resolve both energy crisis and environment problem. It remains challenging to quest suitable photocatalysts for highly efficient H2S splitting. Herein, a serie...detailed
A comprehensive study of the valence state and the local coordination character of Mn1−xYbxS (x = 0; 0.01; 0.05) solid solutions has been performed using X-ray absorption spectroscopy combined with finite difference method calculations. The good agreement between experimental and calculated data...detailed
The oxidation state studies of Mn1-xLnxS (Ln = Dy, Tm, Yb; x = 0; 0.01; 0.05) solid solutions was carried out for the first time using X-ray photoelectron and emission spectroscopy. The binding energy of the S(2p)-, Ln(4d)-, multiplet splitting analysis of Mn(3s)-level and the SKα1-line energy ...detailed
