Synthesis of CuInS 2 nanometric powder by reaction in molten KSCN [PDF]

open access: yesMaterials Letters, 2014
CuInS2 was synthesized, with a yield of 70% by reaction in molten KSCN at 400 °C of CuCl2 and InCl3 with a ratio KSCN/Cu=15. The homogeneous powder obtained is constituted of nano-sized grains (70–100 nm), with a specific surface area of 6 m2/g and a band gap Eg of 1.5 eV.

Influence of the microstructure on the degree of sensitization of a duplex stainless steel UNS S31803 aged at 650ºC [PDF]

open access: yesMaterials Research, 2013
This work evaluates the phase transformations during aging of an UNS S31803 DSS at 650ºC and its influence on the DOS. The material was solution treated at 1175ºC and then aged at 650ºC for times up to 360 h. SEM-BSC images indicate the formation of Cr2N,

Facet‐Dependent Activity of Fe3S4 Crystal in Peroxydisulfate Activation for Organic Pollutants Degradation

open access: yesAdvanced Science, EarlyView.
Fe3S4 crystal with the exposed [001] facet exhibits higher catalytic activity for activating peroxydisulfate (PDS) to degrade clothianidin (CLO), which can be attributed to the dissolved Fe‐induced homogeneous catalytic process; while Fe3S4 crystal with the exposed [1‐21] facet exhibits excellent catalytic stability and durability, thereby boosting the
