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. ...
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 ...
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, ...
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 ...
An evaluation of optical band gap in photovoltaic polymers for solar energy capture
(2019-05-14)
Organic solar cells are a very promising technology for use in the renewable energy field. Band gap measurements on liquid phase for different polymers were studied, and the possible radiation harvest and reasoning for ...
Microstructure and rheology of Janus particle suspensions
(2019-05-15)
The aggregate sizes and morphologies formed with colloidal particles have important consequences on the rheological behavior of colloidal suspensions. Self- and directed-assembly are the most used phenomena to produce ...
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 ...
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 ...
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 ...
