Electrochemical analysis of the dissolution of gold in a copper–ethylenediamine–thiosulfate system

open access: yesGreen Processing and Synthesis, 2023
Thiosulfate gold leaching is a green gold extraction technology. Here, the effects of thiosulfate, copper ion, ethylenediamine, and polarization voltage on the dissolution of gold in this system were investigated by an electrochemical method. The results

Erythrocytes as Carriers of Therapeutic Enzymes. [PDF]

open access: yes, 2020
Therapeutic enzymes are administered for the treatment of a wide variety of diseases. They exert their effects through binding with a high affinity and specificity to disease-causing substrates to catalyze their conversion to a non-noxious product, to ...

Leaching of Gold and Silver from a Complex Sulfide Concentrate in Copper-Tartrate-Thiosulfate Solutions

open access: yesMetals, 2022
The leaching behaviors of gold and silver from a complex sulfide concentrate in copper-tartrate-thiosulfate solutions were investigated in this paper. Experimental parameters, including temperature, initial pulp pH, and concentration of copper, tartrate,

Pelodictyon phaeoclathratifovme sp. nov., a new brown-colored member of the Chlorobiaceae forming net-like colonies [PDF]

open access: yes, 1989
A new strain of the green sulfur bacteria was isolated from the monimolimnion of Buchensee (near Radolfzell, Lake Constance region, FRG). Single cells were rod-shaped, nonmotile and contained gas vacuoles. Typical net-like colonies were formed by ternary

An electrochemical method to investigate the effects of compound composition on gold dissolution in thiosulfate solution

open access: yesGreen Processing and Synthesis, 2020
The electrochemical behavior of gold dissolution in the Cu2+–NH3–S2O32−–EDTA solution has been investigated in detail by deriving and analyzing the Tafel polarization curve, as this method is currently widely implemented for the electrode corrosion ...

Dicyandiamide has more inhibitory activities on nitrification than thiosulfate. [PDF]

open access: yesPLoS ONE, 2018
Dicyandiamide (DCD) and thiosulfates are two type of nitrification inhibitors (NIs) that have been widely used in agriculture to improve nitrogen (N) fertilizer use efficiency and mitigate negative effect of N on environment.

Silver Staining of Proteins in 2DE Gels [PDF]

open access: yes, 2009
Silver staining detects proteins after electrophoretic separation on polyacrylamide gels. Its main positive features are its excellent sensitivity (in the low nanogram range) and the use of very simple and cheap equipment and chemicals.

An electrochemical investigation of the formation of CoSx and its effect on the anodic dissolution of iron in ammoniacal-carbonate solutions [PDF]

open access: yes, 2013
It has been found that the co-presence of cobalt (II) and thiosulphate ions in ammoniacal-carbonate solutions promotes the passivation of iron, under conditions in which it would otherwise continue to dissolve anodically. Electrochemical experiments have

Effects of ammonium thiosulfate and guanyl thiourea as calcium ammonium nitrate inhibitors on fertilization and plants [PDF]

open access: yesChemical Review and Letters, 2019
The effects and decomposition of ammonium thiosulfate and guanyl thiourea, a nitrification inhibitor, are discussed. When ammonium thiosulfate and guanyl thiourea are used as nitrification inhibitors, leaching of ammonium nitrate from calcium ammonium ...
