Single particle dynamics around the boundaries of nematic media 

Parientes-Sánchez, Deyvi A. (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 ...

CO2 adsorption in nickel based metal organic framework Ni-DABCO: A density functional theory and grand canonical Monte Carlo study 

Mulero-Flores, Orlando A. (2018-12-07)
The continuous emissions of greenhouse gases, especially carbon dioxide (CO2), are generating concerns over the negative effects they are having on the planet. The main goal of this project is to understand the adsorption ...

Effect of protic and aprotic polar solvents on the heterogeneous catalytic conversion of hexoses 

Rivera-Goyco, Christian (2018-12-12)
We studied the synthesis, the characterization and the solvent effect on the catalytic performance of materials with Brønsted or Lewis acidity on the hexose conversion towards value-added molecules such as 5-(hydroxymeth ...

Transition metal based complexation materials for the selective adsorption of contaminants of emerging and concern and metabolites from aqueous solutions 

Ortiz-Martínez, Krisiam (2018)
Since the presence of contaminants of emerging concern (CECs) in different water sources was revealed, the development of more efficient technologies for their removal has been a constant challenge for the scientific ...

Poly(styrene-isobutylene-styrene) nanocomposite membranes for fuel cell devices and specialty separation applications 

Ruiz-Colón, Eduardo (2018-05)
Ionic domains were incorporate into sulfonated poly(styrene–isobutylene–styrene) (SO3H SIBS) in an effort to improve the transport properties of the functionalized aromatic block copolymer. The resulting polymer nanocomposite ...

DFT analysis on structure-property relationships of metal-substituted zeolites 

Montejo-Valencia, Brian D. (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 ...

Catalytic conversion of biomass renewable feedstocks to platform molecules using Brønsted acid catalysts 

Oyola-Rivera, Oscar (2018-05)
The fractionation of sugarcane bagasse, plantain peel and brewer’s spent grains to glucose, xylose and lignin was studied using 0.50 and 0.05 wt% H2SO4 as catalyst in a mixture of 80:20 wt% γ-valerolactone:water. We ...

Synthesis and characterization of flexible pillared-layer structured porous coordination polymers and determination of gas adsorption-desorption properties 

Arrieta-Pérez, Rodinson R. (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 ...

Conversion of biomass derived feedstocks to platform molecules using bifunctional mesostructured silica based catalysts 

Reyes-Luyanda, Damian (2018-05)
The combination of Brønsted acidity with metallic functionality in a mesoporous catalyst offers a potential pathway for the conversion of cellulose into sugar alcohols that may be used as a sustainable source of renewable ...

Sulfonated polymer metal nanocomposite membranes with bacterial disinfection activity in water 

Pagán-Pagán, Nataira M. (2018-05)
This study describes the synthesis and characterization of sulfonated poly(styreneisobutylene- styrene) (SIBS) polymer nanocomposite membranes, which show antibacterial properties useful for the inactivation of Enterococci ...
