Sulfonated fluoroblock copolymer membranes for direct methanol fuel cell applications
(2014)
This investigation studied the transport properties of several fluorinated sulfonated membranes for direct methanol fuel cell applications. First, Nafion® membranes were processed with supercritical fluid (SCF) CO2 and ...
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 ...
Particle flow promoted by external forces in a confined space – feed frame case
(2014)
Pharmaceutical tablets are the most sold and preferred drug solid dosage form due to its many advantages. The feed frame was designed to transfer the powder from the hopper to the tablet press dies as the die disk rotates. ...
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 ...
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 ...
Novel synthesis and characterization of supported bimetallic films for hydrogen detection
(2014)
Continuous increase in energy demand and high levels of pollution generated by the existing energy sources have led researchers to explore other clean and renewable alternatives. Hydrogen gas (H2) is an option that has ...
Porous carbon-faujasite composites containing transition metals for aqueous phase adsorption applications
(2014)
Pharmaceutical and personal care products (PPCPs) have emerged in surface water in concentration levels enough to categorize them as “emerging contaminants” due to a lack of efficient wastewater treatment plant removal ...
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 ...
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, ...
Effect of operational and design parameters on the early stages of high shear wet granulation processes
(2014)
The development of new technologies, active ingredients and regulatory initiatives, has increased the need for a scientific understanding of the pharmaceutical manufacturing processes. In this context, solid dosage forms ...
