Mechanochemical activation of chalcopyrite: Relationship between activation mechanism and leaching enhancement
TL;DR: In this paper, the mechanochemical activation of chalcopyrite by vertically stirred ball milling (VSBM) was used to enhance copper dissolution in leaching, and the contribution of each activation mechanism to leaching enhancement was assessed by two-stage leaching.

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.
