First-principles calculations of the thermodynamic mixing properties of arsenic incorporation into pyrite and marcasite
(ELSEVIER, 2006-01-31)
The thermodynamic mixing properties of As into pyrite and marcasite have been investigated using first-principles and Monte Carlo calculations in order to understand the incorporation of this important metalloid into solid ...
Structural analysis of adsorption processes of 5FU and imiquimodon hydrogels using AMBER/PM3 hybrid model
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Química, 2018-05-01)
AMBER/PM3 hybrid model allowed determining the structural properties of 5FU and imiquimod individually and after the adsorption of chitosan hydrogels crosslinked with genipin, respectively. It was observed that the Gibbs ...
Desarrollo de una aplicación para el cálculo de las propiedades de la mezcla amoniaco-agua
(Universidad Pedagógica y Tecnológica de Colombia, 2017-07-04)
The design and optimization of energy systems are very important today. Some of these systems use the ammonia-water mixture as working fluid, therefore, calculation of the thermodynamic properties becomes indispensable for ...
Effect of the temperature in adsorption phenomena of water onto Sub-Bituminous coal
(Universidad Nacional de Colombia - Sede Medellín - Facultad de Minas, 2016-01-01)
The presence of water in coal presents a technological challenge for its industrial use in energetic processes. Therefore, this study aims to study the temperature effect on the water adsorption onto coals at 21, 30, 40 ...
Adsorption of poly-2-(dimethylamino) ethylmethacrylate-N-alkyl quaternized at the water/chloroform interface
(ELSEVIER SCIENCE BV, 2010-05-04)
The interfacial properties of poly-2-(dimethylamino) ethyl methacrylate-N-alkyl quaternized with octyl,
decyl, dodecyl and tetradecyl bromide are studied from the chloroform to the water/chloroform interface.
In order ...
DNA secondary structure formation by DNA shuffling of the conserved domains of the Cry protein of Bacillus thuringiensis
(2017-12)
Background
The Cry toxins, or δ-endotoxins, are a diverse group of proteins produced by Bacillus thuringiensis. While DNA secondary structures are biologically relevant, it is unknown if such structures are formed in ...
A new computational tool for the development of advanced exergy analysis and LCA on single effect LiBr–H2O solar absorption refrigeration system
(Corporación Universidad de la Costa, 2021)
Evaluation of irreversibility in an ammonia-water absorption refrigeration system using three different mathematical models to calculate the thermodynamic properties
(Universidad Pedagógica y Tecnológica de Colombia, 2018-01-01)
As análises por Segunda Lei, ou de Exergia, nos Sistemas de Refrigeração por Absorção (SRA) são muito
importantes, já que permitem realizar análises de optimização de acordo com o trabalho disponível, os quais
se estabelecem ...
