In situ recovery of copper sulfide ores: alternative process schemes for bioleaching application
(Elsevier, 2020)
There is a growing interest in exploring the application of bioleaching for treating copper sulfide ores of decreasing grade and located at larger depth by in situ recovery (ISR) for its potential savings in ore extraction, ...

In-situ spectroelectrochemistry (UV-visible and infrared) of anodic films on iron in neutral phosphate solutions
(Pergamon-Elsevier Science Ltd, 2000-02)
The composition of anodic films on iron formed at different potentials in neutral solutions has been investigated by in-situ UV-vis and IR spectroscopies in the presence of PO43-, a non-contaminant inhibitor used in ...
The Addition of Propylene Glycol Alginate to a Fluoride Solution to Control Enamel Wear: An in situ Study
(2020-12-01)
The aim of this study was to evaluate the protective effect of propylene glycol alginate (PGA) associated with sodium fluoride (NaF) against enamel erosion and erosion-abrasion. A 4-phase, split-mouth, double-blind, crossover ...
Changes on iron electrode surface during hydrogen permeation in borate buffer solution
(Pergamon-Elsevier B.V. Ltd, 2008-04-01)
Hydrogen interaction with oxide films grown on iron electrodes at open circuit potential (E-oc) and in the passive region (+0.30 V-ECS) was studied by chronopotentiometry, chronoamperometry and electrochemical impedance ...
