TL;DR: The results demonstrate the technical viability of recovering copper using mechanical processing followed by an electrometallurgical technique and the copper obtained by electrowinning is above 98% in most of the tests.

TL;DR: In this article, a thermodynamic analysis of an ethanol/water system, using the Gibbs energy minimization method, has been carried out, and a mathematical relationship between Lagrange's multipliers and carbon activity in the gas phase was deduced.

TL;DR: A literature review onprinted circuit boards is presented, showing their structure and materials, the environmental problem related to the board, some the different alternatives for recycling, and some solutions that are being studied to reduce and/or replace the solder, in order to minimize the impact of solder on the printed circuit boards.

TL;DR: In this paper, the electrolytic codeposition of nickel composite coatings with different amounts of polyaniline particles (PAni) was used to produce electrodes for the catalytic hydrogen evolution reaction (HER).

TL;DR: In this paper, the corrosion behavior of AZ91 magnesium alloy treated with a 4% (v/v) methyltriethoxysilane (MTES) alcohol solution, with and without an alkaline pretreatment, was investigated.
