Single particle dynamics around the boundaries of nematic media
(2018-10-31)
Brownian motion of a colloid suspended in a lyotropic chromonic liquid crystal (LCLC's) leads to the description of the transport properties of the medium through a unification of theories where the confinement effect is ...
DFT analysis on structure-property relationships of metal-substituted zeolites
(2018-05)
Metal-modified zeolites have proven to be effective catalysts for various important reactions involving the transformation of biomass-derived molecules and the conversion of greenhouse gases, such as CO2 and CH4. In this ...
Influence of interparticle magnetic interactions on heat dissipation in magnetic nanoparticles and magnetomicelles
(2013)
Magnetically actuated nanovectors are prepared through the combination of magnetic nanoparticles and thermoresponsive materials that facilitate the release of the drug when heated at a temperature slightly above the normal ...
Optimization of a fluid bed dryer by the implementation of a model predictive controller
(2006)
Optimization of the drying operation requires a model containing the operating variables for fluid bed dryers (FBD). Modeling of FBD is still uncertain since the drying process is unpredictable and relies on empirical ...
Rheology of rodlike nanoparticle suspensions in lyotropic liquid crystalline polymers
(2013)
Liquid crystalline polymers are ideal to develop oriented and anisotropic materials. The incorporation of a nanoparticle may improve or add properties to a matrix. Small concentrations of particles smaller than the liquid ...
Synthesis and characterization of flexible pillared-layer structured porous coordination polymers and determination of gas adsorption-desorption properties
(2018-05)
Porous coordination pillared-layer structured polymers are a particular category of 3D uniform crystal materials constituted by well-defined two-dimensional layers (specially formed by a combination of metal ion or metal ...
Atomic pair distribution study of the growth of Pt nanoparticles in zeolites
(2016)
The Pair Distribution Function (PDF) is a total scattering method used to study the local structure of a material and yields a function in real space with peaks that represent the interatomic distances. In this work, we ...
Modeling of TNT transport from landmines
(2008)
The transport of Explosive Related Compounds (ERCs) has been studied as part of a research program aiming to the development of chemical sensors for detecting landmines. TNT and its degradation products typically make up ...
Bifunctional catalysts with improved hydrothermal stability for the hydrolytic hydrogenation of cellulose into polyols
(2014)
The increase in the world’s energy needs has caused a renewed interest in finding green ways to produce fuels. In this work, we present a study of the hydrolytic hydrogenation of cellulose on bifunctional catalysts for the ...
Thermogravimetric characterization of polystyrene-based, triblock copolymers: effects of sulfonation, counter-ion substitution, number average molecular weight, and polystyrene weight fraction
(2010)
In this study, poly (styrene-isobutylene-styrene) (SIBS) was characterized using thermogravimetric analysis. The thermal behavior of three types of SIBS, with different average number molecular weight, Mn , and polystyrene ...
