Estudio termodinámico de la solubilidad de sulfadiazina en mezclas acuosas de Carbitol y N-Metil-Pirrolidona
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias FarmacéuticasDepartamento de FarmaciaFacultad de CienciasUniversidad Nacional de Colombia - Sede Bogotá, 2021-02)
In the present study, the solubility of sulfadiazine in aqueous mixtures of Carbitol and N-methyl-2-pyrrolidone (NMP) at 278.15 K - 313.15 K was analyzed. It was found that the solubility of sulfadiazine in aqueous Carbitol ...
Efficient and eco-friendly synthesis of iodinated aromatic building blocks promoted by iodine and hydrogen peroxide in water: a mechanistic investigation by mass spectrometry
(Elsevier B.V., 2012-10-03)
The reaction of aromatic and heteroaromatic compounds with molecular iodine in the presence of aqueous hydrogen peroxide using water without any co-solvent at 50 degrees C for 24 h produced versatile iodinated organic ...
Mejoras de las propiedades funcionales de enzimas industriales mediante la preparación de nuevos derivados de enzimas inmovilizadas sin soportes.

Development of self-microemulsifying lipid-based formulations of trans-resveratrol by systematically constructing lipid-surfactant-water phase diagrams using long-chain lipids
(Taylor & Francis, 2021-07)
The aim of this work was to develop self-microemulsifying lipid-based formulations of trans-resveratrol in cod liver oil, a long chain lipid, to increase its solubility, dissolution rate and oral bioavailability. Ternary ...
Measurement of the phase behavior of the ternary system carbon dioxide + acetone + phenanthrene
(American Chemical Society, 2006-01)
As a representative model system for the gas-anti-solvent (GAS) process, the phase behavior of the ternary system carbon dioxide + acetone + phenanthrene has been studied experimentally. Carbon dioxide was chosen as the ...
One-pot biosynthesis of idoxuridine using nanostabilized lactic acid bacteria
(Elsevier, 2017-11)
An efficient bioprocess using immobilized lactic acid bacteria to obtain 5-iodouracil-2′-deoxyriboside, known as idoxuridine, is reported. This nucleoside analogue is an antiviral agent used in the treatment of viral ...
Understanding the extraction capabilities of the Helix Supercritical Fluid System
(Universidad EAFITIngeniería de ProcesosEscuela de Ingeniería. Departamento de Ingeniería Procesos, 2018)
Supercritical fluids extraction is a separation technique, which has higher yields and lower extraction times than conventional extraction techniques -- Moreover, due to the general use of carbon dioxide a supercritical ...
