Recent synthetic efforts in the preparation of 2- (3,4)-alkenyl (aryl) quinoline molecules towards anti-kinetoplastid agents
(2019-12-19)
Leishmaniasis, Chagas disease and African sleeping sickness have been considered some of the most
important tropical protozoan afflictions. As the number of drugs currently available to treat these human
illnesses is ...
Methylene Blue Photodegradation under Visible Irradiation on Ag-Doped ZnO Thin Films
(2019-09-04)
This study synthesized and characterized Ag-doped ZnO thin films. Doped ZnO powders were synthesized using the sol-gel method, and thin films were fabricated using the doctor blade technique. The Ag content was determined ...
Physical-chemical study of anthracene selective oxidation by a Fe(III)-phenylporhyrin derivative
(2019-10-30)
In this work, we studied the anthracene oxidation by hydroxyl radicals. Hydroxyl radical was generated by reaction of 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin Fe (III) (TPPFe) with hydrogen peroxide under visible ...

A COMPREHENSIVE ANALYSIS OF CRITICAL VARIABLES USED TO DESIGN A SPRAY DRYER OF WHEY PROTEIN CONCENTRATES
(2019-11-12)
Five models of a spray dryer design for a whey protein process were analyzed
in this study. These models include first principle approaches and empirical
correlations. From a large set of given design specifications ...
A NOTE ON PRESERVATION OF SPECTRA FOR TWO GIVEN OPERATORS
(2019-03-06)
We study the relationships between the spectra derived from Fredholm the-
ory corresponding to two given bounded linear operators acting on the same space. The
main goal of this paper is to obtain sufficient conditions ...
Production and characterization of activated carbon from coal for gold adsorption in cyanide solutions
(2019-06-06)
En este trabajo se produjeron carbones activados utilizando carbón mineral como materia prima procedente de siete zonas
carboníferas colombianas. La activación física se efectuó en dos etapas: una etapa de carbonización ...
Removal of the direct navy-blue dye on modified coffee bean
(2019-10-19)
The presence of dyes in water bodies inhibits the penetration of light,
affecting the flora and fauna of these ecosystems, which is why, greater
efforts are made to eliminate them before being poured. This study allowed ...
