Blend uniformity and powder phenomena inside the continuous tumble mixer using experiments and DEM simulations
(2014)
The pharmaceutical industry is in the middle of a major transition regarding manufacturing where continuous operation is a central topic. One of these operations is powder mixing, which could arguably be the principal ...
Kinetics and modeling of batch bioethanol production using suspended co-cultures of Saccharomyces cerevisiae and Pichia stipitis in glucose-xylose media
(2010)
A mathematical structured model was developed to predict the behavior of glucosexylose mixtures using the suspended co-culture of the wild-type yeast strains Saccharomyces cerevisiae Montrachet and Pichia stipitis NRRL ...
Silicoaluminophosphate nanoporous materials for carbon dioxide adsorption at low concentration
(2011)
The incorporation of extraframework Sr2+ and Ba2+ cations onto silicoaluminophosphate (SAPO-34) zeolitic materials has been proven to influence their adsorptive properties. In this study, three approaches were employed to ...
Brackish water desalination with a novel polymer nanocomposite membrane
(2019-04-05)
The rapid growth of the global population, the industrialization and environmental problems caused by global warming have made it necessary to implement advanced water purification techniques capable of fulfilling the ...
Synthesis and characterization of a novel palladium nanostructured ensemble supported on anodized alumina substrates for hydrogen sensing applications
(2015)
Hydrogen is a versatile molecule used in many industrial processes. Hydrogen is flammable at concentrations between 4% to 75% v/v at atmospheric pressure with a tendency to leak. There are a variety of hydrogen sensors, ...
Functionalization and characterization of Sulfonated Poly (Styrene-Isobutylene-Styrene) membranes for fuel cells and specialty separation applications
(2014)
In this study, the transport properties of poly(styrene-isobutylene-styrene) (SIBS) block copolymer were determined as a function of sulfonation level (0-94.9 %), counter ion substitution (Ba+2, Ca+2, Mg+2, Mn+2, Cu+2, ...
Testing of centrifugal filter devices as a tool to quantify protein-nanoparticle interactions using UV/Vis measurements
(2012)
Centrifugal Filter Devices (CFD) has been tested for the quantification of protein adsorption onto the surface of magnetic nanoparticles coated with biocompatible polymers. Using a phosphate buffered saline wash protocol, ...
Catalytic conversion of CO2 to hydrocarbons
(2014)
The production of methanol and dimethyl ether via CO2 hydrogenation was studied using Pd catalysts supported on α-Ga2O3, α-β-Ga2O3 and β-Ga2O3 polymorphs. The catalytic activity improves with the increase in the content ...
Molecular simulation studies for the templated synthesis of ultrathin metal nanowires in zeolites
(2012)
In the present work geometric optimizations, Metropolis Monte Carlo, and molecular dynamics simulations were done to study the feasibility of synthesizing Ni and Pt nanowires inside the pores of one dimensional zeolite ...
DFT study on the effect of aluminum atom distribution in zn-exchanged mfi zeolites for methane c-h bond activation
(2018)
The direct conversion of methane to useful chemicals is economically attractive owing to the vast availability of natural gas resources. Nevertheless, a fundamental limitation is the chemical inertness and stability of the ...
