Oxygen Management During Alcoholic Fermentation
Oxygen additions are a common practice in winemaking, as oxygen has a positive effect in fermentative kinetics, biomass synthesis and improvement of color, structure and :flavor in treated wines. However, most oxygen ...
Conditions of subaerial weathering of basalts in the Neoarchean and Paleoproterozoic
(Elsevier Science BvAmsterdamHolanda, 2014)
ELECTROCHEMICAL STUDY OF THE CATALYTIC INFLUENCE OF SULFOLOBUS METALLICUS IN THE BIOLEACHING OF CHALCOPYRITE AT 70 DEGREES C
(ELSEVIER SCIENCE BV, 2006)
The catalytic influence of Sulfolobus metallicus in bioleaching of chalcopyrite at 70 degrees C and pH 1.7 was characterized from studies of anodic dissolution of a chalcopyrite concentrate at constant potential. Experiments ...
A POSSIBLE PATH FOR MERCURY IN BIOLOGICAL-SYSTEMS - THE OXIDATION OF METALLIC MERCURY BY MOLECULAR-OXYGEN IN AQUEOUS-SOLUTIONS
(Elsevier Science BvAmsterdamHolanda, 1995)
KINETICS OF THE PRESSURE LEACHING OF SULFIDIZED CHALCOPYRITE IN H2SO4-O2 MEDIA
(CURRAN ASSOCIATES, 2013)
An environmentally friendly route to copper extraction from chalcopyrite by a combination of pyrometallurgy and hydrometallurgy is the sulfidation process which consists of roasting chalcopyrite with sulfur at 350 - 400°C ...
2,4-Dichlorophenoxyacetic acid (2,4-D) degradation promoted by nanoparticulate zerovalent iron (nZVI) in aerobic suspensions
Reactive species generated by Fe0 oxidation promoted by O2 (catalyzed or not by ligands) are able to degrade contaminant compounds like the herbicide 2,4-dichlorophenoxyacetic acid. The degradation of 2,4-D was influenced ...
Cyclodextrine-nanoencapsulation of niclosamide: Water solubility and meaningful enhancement of visible-light—Mediated sensitized photodegradation of the drug
(Elsevier Science Sa, 2017-11)
A kinetic and mechanistic study of the daylight-mediated photooxidation of the multifunctional drug Niclosamide (NSD) was carried out in aqueous solutions. NSD is a frequent contaminant suspended in natural waters. The ...
