Cost analysis of local bioproducts processing plant using microalgae biomass feedstock
(2012)
The need to produce bioproducts useful for the human wealth derived from microalgae, such as proteins, lipid and carbohydrates is gaining importance in recent years. In spite of the broad availability of technologies for ...
Flexible titanium silicate porous materials for selective carbon dioxide adsorption
(2013)
Flexible titanium silicates are Zorite-like synthetic materials in which their framework atoms’ configuration exhibits mixed oxides containing tetrahedrally coordinated silicon and squaredpyramidal/octahedral titanium ...
Conversion of carbohydrates to alpha-hydroxy-acids over Lewis acidic HF-, SN- and ZR- beta zeolite catalysts using gamma-valerolactone and water as solvent
(2019-07-10)
The incorporation of Sn, Hf and Zr in the structure of Beta zeolite using a post-synthetic method gives catalysts with Lewis acidity that are effective for the conversion of C6 sugars to alpha-hydroxy acids (AHAs), such ...
Synthesis and characterization of modified mesoporous silicates for the adsorption of pharmaceutical and personal care products
(2011)
PPCPs have been recently identified as emerging contaminants due to their persistence in our potable water supply and aquatic systems. Unfortunately, traditional water treatment methods are inadequate for the removal of ...
Probing nanoscale viscosity in polymer melts using magnetic nanoparticles.
(2012)
Oleic acid coated cobalt ferrite nanoparticles (CoFe2O4-OA), which relax through the Brownian mechanism, were dispersed in Polystyrene (PS) and Polybutadiene (PBD) of various molecular weights (MW). These suspensions were ...
Enhanced potentiation of anticancer drugs using magnetic fluid hyperthermia (MFH): In vitro and in vivo studies
(2014)
Clinical studies have demonstrated the effectiveness of combined hyperthermia and anticancer drug treatments. Challenges related to effective heat transfer have limited its clinical application. The use of magnetic fluids ...
Computational study of the physical adsorption of CO₂ on novel sorbents based on porous coordination polymers
(2017)
CO2 capture has motivated the design and synthesis of a large number of adsorbent materials. An example of these materials are the coordination pillared-layers (CPLs), which have emerged as possible candidates for CO2 ...
Catalytic conversion of biomass renewable feedstocks to platform molecules using Brønsted acid catalysts
(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 ...
Improving continuous manufacturing process reliability through feeding control system
(2018-12-12)
Continuous manufacturing processes are complex systems composed of multiple unit operations where process variables and material properties interaction allow the development of soft PAT sensors. Hence, this study was focused ...
Effect of protic and aprotic polar solvents on the heterogeneous catalytic conversion of hexoses
(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 ...
