Screening soil metagenomic libraries searching for degrading enzymes useful for the production of biofuels and value added chemicals
(2012)
Value-added chemicals and fuels produced via the biotransformation of lignocellulosic biomass resources like crop biomass waste are necessary to reduce our dependence on the non-renewable conversion of raw materials. ...
Electrical characterization of sulfonated poly(styrene-isobutylene-styrene) triblock copolymer thin films
(2015-05)
Polymers are a fundamental part of electronic systems and are widely used due to their low cost, ease of processing, and their wide range of mechanical and electrical properties. They have traditionally been used as passive ...
Experimental and numerical study of the continuous fluidized bed dryer
(2016)
Nowadays, batch fluid-bed drying is one of the most efficient drying methods for particulate material; but at the same time, it is the most energy consuming operation in the manufacturing of solid dosage forms. To minimize ...
BCS class II drug dispersions in hydroxypropyl methylcellulose solutions: The effect of polymer molecular weight and drug loading on the steady-state rheology of HPMC solutions
(2015)
Physical biopolymer gels are ideal candidates for the drug delivery of solid pharmaceutical drugs. Nevertheless, inclusion of particles may affect the rheology and gelation of these systems. In this work, we evaluate the ...
Targeting PDMS hydrophobicity for study of small hydrophobic molecule-driven cell responses in vitro
(2018)
Poly(-dimethyl siloxane) (PDMS) has been the main polymer employed in micro and nano scale devices. Its chemical and physical properties are ideal for molding and soft patterning of microfluidic devices. Despite the great ...
Biotransformation of coffee pulp using filamentous fungi
(2012)
Efforts devoted to the efficient use of agro-industrial residues have increased, especially if the use contributes to solve pollution problems. Coffee pulp/husk is the main byproduct generated during coffee wet processing. ...
Sonolysis of pharmaceutical and personal care products as an advanced oxidation process for the remediation treatment of wastewater effluents
(2007)
Pharmaceutical and Personal Care Products (PPCPs) are a diverse group of chemicals, also known as xenobiotics, treated like potential environmental pollutants. Recently, PPCPs have been detected in trace amounts in surface ...
Nanostructured bimetallic copper-gallium catalysts for the production of methanol from carbon dioxide
(2018-12-12)
The hydrogenation of carbon dioxide (CO2) to methanol is an alternative to mitigate the problems caused by global warming. Industrially, methanol is produced by hydrogenation of CO2/CO over heterogeneous catalyst Cu/ZnO/Al2O3. ...
Characterization of proton exchange membrane fuel cell and PEM electrolyzer using non-steady electrochemical techniques.
(2004)
Proton Exchange Membrane Fuel Cells (PEMFCs) and PEM Electrolyzer were
characterized using Electrochemical Impedance Spectroscopy (EIS). Faradaic resistance
(RΩ), kinetic and mass transfer parameters such as charge ...
Polymeric nanocarriers for the enhancement of enzyme replacement therapy in lysosomal storage diseases: A proof of concept study
(2016)
Lysosomal Storage Diseases (LSDs) are a group of inheritable genetic diseases caused by mutant lysosomal enzymes, leading to the accumulation of undigested macromolecules in the lysosomes and causing increases in lysosome ...
