Interrelationship of hydrology, microbial colonisation and hydrometallurgy in a simulated chalcopyrite heap leach [PDF]
, 2008 Includes bibliographical references (leaves 104-115).Chalcopyrite is the most abundant primary copper sulphide mineral found worldwide. As copper grades of ores available for extraction decrease, heap bioleaching is gaining interest as a potential ...

Origin of Fe3+ in Fe-containing, Al-free Mantle Silicate Perovskite
, 2015 We have studied the ferrous (Fe2+) and ferric (Fe3+) iron concentrations in Al-free Fe containing Mg-silicate perovskite (Mg-Pv) at pressure (P), temperature (T), and oxygen fugacity (fO2) conditions related to the lower mantle using a thermodynamic ...

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms
Advanced Materials, EarlyView.This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Advanced Materials, EarlyView.This work unveils the multifunctional roles of Prussian blue analogs (PBAs) within the LPSCl matrix, where they act as effective moisture scavengers and enable partial recovery of electrochemical performance. In addition, owing to their relatively soft nature, PBAs help mitigate interfacial stress and thereby enhance electrochemical stability and ...
