Advanced Functional Materials, EarlyView.A strongly correlated electron system (SCES) exhibits pronounced insulating behavior due to Coulombic repulsion between cations, which generates a charge gap. This study investigates the tuning of the band structure in NiWO4‐based SCES via Cu doping at substitutional sites and Li doping at interstitial sites.

Beneficiation of calcined colemanite tailings
Powder Technology, 1993 Abstract The tailings produced from the calcination of Bigadic colemanite ore are upgraded by means of a gravity concentration method. The experiments were conducted in two separate fractions. The coarse (−1+0.5 mm) and the fine (−0.5 mm) tailing fractions containing respectively 20.01% and 36.31% B2O3 were treated on a Deister Superduty Diagonal ...
