Modeling of Phase and Chemical Equilibrium on the Quaternary System Acetic Acid, n-Butanol, Water and n-ButylAcetate
(The Berkeley Electronic Press, 2009-09)
The correlation of the data for phase and chemical equilibrium in acetic acid-n-butanol-watern- butylacetate is presented. The azeotropic properties, the topological structure and the existence of a reactive azeotrope are ...
Modifying electronic properties of ICBA through chemical substitutions for solar cell applications
(2017-08-01)
Fullerene derivatives are the most widely used type of acceptor material in the organic solar cells (OSCs) active layers, but there are still some problems to be overcome, such as increased solubility and adjustment of the ...
The Chemical Percolation Devolatilization Model Applied to the Devolatilization of Coal in High Intensity Acoustic Fields
(Sociedade Brasileira de Química, 2002-06-01)
Neste trabalho, um modelo de percolação química (CPD), desenvolvido para o cálculo da evolução dos produtos de pirólise de partículas de carvão, foi estendido de forma a ser empregado em regimes de degradação térmica sobre ...
Survey on chemical, physical, and thermal prediction behaviors for sequential chemical treatments used to obtain cellulose from Imperata Brasiliensis
(2020-01-01)
The effects of chemical treatment sequences on the chemical, physical, and mainly the thermal properties of Imperata Brasiliensis grass in the process used to obtain cellulose fibers were analyzed. The thermal properties ...
Organic acids and high soil CO2 drive intense chemical weathering of Hawaiian basalts: Insights from reactive transport models
(Elsevier, 2019)
We have investigated how biota contributes to rapid chemical weathering of Hawaiian basalts using a reactive transport model and chemical data from a soil chronosequence. These Hawaiian soils have developed under a tropical ...
Understanding Chemical Reactivity in Extended Systems: Exploring Models of Chemical Softness in Carbon Nanotubes
(PEKING UNIV PRESS, 2018)
Chemical reactivity towards electron transfer is captured by the Fukui function. However, this is not well defined when the system or its ions have degenerate or pseudo-degenerate ground states. In such a case, the first-order ...
