Comparative study on bioleaching of two different types of low-grade copper tailings by mixed moderate thermophiles
TL;DR: In this paper, the authors compared the bioleaching behavior of two different types of low-grade copper tailings, acid-leaching tailings and copper flotation tailings by mixed moderate thermophiles, and the variation of mineralogical and microbiological characteristics during their dissolution processes.

Effects of redox potential on chalcopyrite leaching: An overview
TL;DR: In this paper, the impact of redox potential on chemical leaching and bio-leaching of chalcopyrite, reported in previous publications, are summarized and explained by the band theory.

TL;DR: In this article, the authors studied the interfacial solution chemistry in situ at polarised chalcopyrite and chalcocite, using scanning electrochemical microscopy (SECM), and observed that the copper species detected at an ultramicroelectrode positioned at the mineral:solution interface vary between the two minerals, and are dependent upon both the potential of the mineral and the polarisation time.

Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.

Photoelectron spectroscopy : principles and applications
TL;DR: In this paper, the three low-index faces of a Face-Centered Cubic (fcc) Crystal Face were modeled as 3D cubic faces, and a table of binding energies was presented.
