Impact of the titania nanostructure on charge transport and its application in hybrid solar cells
(Springer, 2018-03)
Porous titania films are widely studied in a number of optoelectronic applications due to its favorable optical and electronic characteristics. Mesoporous titania thin films (MTTFs) with tunable pore size, pore order, ...
Mathematical modeling of the enzymatic saccharification process of lignocellulosic biowaste
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-11)
Lignocellulose is a biowaste produced in large quantities by industries; approximately 181.5 billion tons are produced annually in the world. This makes this type of residue a qualifiable candidate resource of energy, which ...
Blanching of red beet (Beta vulgaris L. var. conditiva) root. Effect of hot water or microwave radiation on cell wall characteristics
(Elsevier Science, 2013-07)
The effect of enzymes inactivation through traditional (water, 90 C) and microwave blanching (constant power of 350Wand changing power with values higher than 900W) on cell wall polysaccharides as well as on microstructure ...
Nanofibrous membranes as smart wound dressings that release antibiotics when an injury is infected
(Elsevier Science, 2019-12-03)
Simple and coaxial electrospinning were used for the preparation of nanofibers containing antibiotic. The use of a pH-sensitive polymer provided the membranes with a selective releasing capability, as a function of the ...
Chitosan applications on pharmaceutical sciences: A review
(Bentham Science Publishers, 2019-04)
Background: Chitosan (CS) is a biomaterial derived from chitin, known for its excellent biological properties. One of the most interesting features of CS is its potential for chemical derivatization, which makes it a ...
Persistent organic pollutants sorbed in plastic resin pellet: “Nurdles” from coastal areas of Central Chile
(Pergamon-Elsevier Science Ltd, 2020-02)
Plastic resin pellets were collected from coastal areas (n = 7) of central Chile. Pellets were analyzed using Fourier-transform infrared spectroscopy for polymer identification and gas chromatography–mass spectrometry for ...
Dinámica de fluidos en sistemas complejos mediante estudios de Resonancia Magnética
(2015-12)
Una herramienta de caracterización indirecta para estudiar sistemas porosos, que es muy utilizada tanto en medicina como en la industria del petróleo, es la Resonancia Magnética Nuclear (RMN). En esta tesis se estudiaron ...
Influence of exchange in NMR pore size/relaxation correlation experiments
(Elsevier Science, 2018-10)
The influence of molecular exchange in porous polymeric systems on experiments that simultaneously correlate and determine pore length scales and surface relaxivities is studied. Pore length scales are determined by taking ...
Functional clays as reinforcement of nitrile latex films
(Elsevier, 2019-04)
Latex films with novel properties were prepared by latex compounding. The objective of this work is to evaluate the influence of a clay containing antiseptic agent on the properties of latex films of acrylonitrile butadiene ...
