La amplia distribución de un microorganismo termoacidófilo en el mineral de una mina cuprífera a temperatura ambiente y en condición ácida, y su importancia en la biolixiviación del concentrado de calcopirita
The wide distribution of an extremely thermoacidophilic microorganism in the copper mine at ambient temperature and under acidic condition and its significance in bioleaching of a chalcopyrite concentrate

Rev. argent. microbiol; 51 (1), 2019
Thermoacidophiles can exist in a state of dormancy both in moderate temperatures and even in cold conditions in heap leaching. Sulphide mineral ores such as chalcopyrite produce sulfuric acid when exposed to the air and water. The produced sulfuric acid leads to the decrease of pH and exothermic reaction...

Investigation on the biological effect of fluorine present on the surface of titanium implants: analysis of the reaction fluoride-titanium oxide

Actual. osteol; 13 (1), 2017
The aim of this work was to investigate the state of fluoride at the surface of fluoridemodified titanium implants, and to provide information to support or discard the hypothesis that fluoride ion participates in the osseointegration of implants. Titanium is coated with a 2-10 nm thick layer of stable a...
