Role of iron in the enhanced reactivity of pulverized Red mud: Analysis by Mössbauer spectroscopy and FTIR spectroscopy

Case Studies in Construction Materials, 2019
The present study is carried out to investigate the contribution of iron in the hematite phase in enhancing the reactivity of red mud. Compressive strength test was performed on the binder synthesized from both unpulverized and pulverized red mud.

Mechanochemical Synthesis of Cu2MgSn3S8 and Ag2MgSn3S8 [PDF]

, 2020
Two new thiospinels of the type AI2BIICIV3SVI8 were successfully synthesized via a mechanochemical route using binary sulfides and sulfur. Cu2MgSn3S8 and Ag2MgSn3S8 are the first AI2BIICIV3SVI8 compounds with magnesium as divalent cation.

High Spin Iron–Phosphinidene and Arsinidene Complexes With Attenuated Metal–Ligand Multiple Bond Character

Angewandte Chemie, EarlyView.
Unusually low metal–ligand bond orders are observed in high spin iron(II) pnictogenidene (PH2– and AsH2–) complexes. Electronic structure analysis provides evidence for multiconfigurational character that attenuates the metal–ligand multiple bond character normally that is typically associated with pnictogenidene ligands. These complexes can be used to

Moessbauer and magnetic measurements of superconducting LiFeP

, 2010
The LiFeP sample has been prepared by means of high-temperature solid state reaction. A transition temperature to the superconducting state was found as about 5.5 K by measurements of magnetization versus temperature.

Low‐Temperature Reverse Water–Gas Shift Enabled by Magnetically Induced Catalysis

Angewandte Chemie, EarlyView.
Magnetically induced catalysis using standard Cu–Al spinel‐derived catalyst functionalized with carbon‐coated iron nanoparticles enables high CO yield (up to 62%) at mild catalyst and reactor temperatures (estimated at 300°C and determined as 25–123°C, respectively).
