Elution strategies for recovery of nickel and cobalt from laterite tails through scavenging resin-in-pulp [PDF]
, 2012 Ion exchange resin has been used to recover value metal in the uranium and gold industry through resin-in-pulp/leach and similar carbon-in-leach/pulp processes for decades.

Nickel-Catalyzed Difluoroalkylation–Alkylation of Enamides
, 2019 Nickel-catalyzed carbodifunctionalization of alkenes is an efficient strategy for the construction of C–C bonds. However, applications of the strategy in dialkylation of alkenes remain underdeveloped due to the difficulties in suppressing competitive ...

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?
Advanced Materials, EarlyView.The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

Sizing nickel iron batteries for RAPS systems
, 2011 Nickel-iron batteries have long life expectancy and are tolerant of abuse or poor charge regimes. However their larger internal impedance often results in premature voltage cut-out with remote area power supplies (RAPS) inverters. A new method for sizing

Advanced Materials, EarlyView.Our work introduces a new framework that fundamentally changes how orientation in bismuth oxyhalide systems is approached. Comprehensive experiments, backed by theoretical models, reveal the pivotal role of halide anions to modify the van der Waals stacking energies required to direct orientation. Our method enables the fabrication of near perfect (001)

Advanced Materials, EarlyView.Environmental Synthesis Radar (ESR) evaluates the environmental impact of (early‐stage) multi‐step chemical syntheses, providing a holistic view by using 18 midpoint impact categories. Unlike conventional life‐cycle assessment (LCA) approaches, ESR reveals three complementary metrics: overall impact Vtotal, environmental hotspots VEF, and critical ...
