Evaluation and modulation of electrospun collagen nanofiber diameter
(2016)
Electrospinning is a process for generating ultrathin fibers from a polymeric fluid using an electric field. It is relatively easy to implement, but it is itself complex due to the many parameters that govern the formation ...
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 ...
Pillar-layered structured nanoporous coordination polymers for carbon dioxide adsorption-based applications
(2013)
Porous coordination polymers (PCPs) have been of great interest for scientist and engineers due to their potential use in applications such as heterogeneous catalysis, molecular storage, and gas separation via adsorption. ...
Synthesis and characterization of porous inorganic adsorbents for the removal of PPCPs via complexation and size exclusion principles
(2013)
Pharmaceutical and personal care products (PPCPs) are considered emerging contaminants that present great challenges for their remediation from water systems. Unfortunately, traditional water treatment methods are not ...
Synthesis and characterization of Sulfonated Poly(Styrene-Isoprene-Styrene): Effects of linear vs branched morphology and counter-ion substitution
(2009)
This investigation studied the resulting nanostructure of ionic membranes composed of sulfonated copolymers with thermoplastic and elastomeric blocks. Linear poly(styrene-isoprenestyrene) (L-SIS) and branched poly(styren ...
Simulations of the magnetization and magnetoviscosity of dilute magnetic fluids
(2009)
In this work was studied the rotational Brownian motion of magnetic spherical and tri-axial ellipsoidal particles suspended in a Newtonian fluid, in the dilute suspension limit, under applied shear and magnetic fields by ...
In situ diffraction studies of Ni nanostructure growth using microporous materials as supports
(2009)
Our objective is to study the growth mechanism of Ni nanostructures supported in microporous materials using X-ray diffraction. Since only the surface atoms of a catalyst are active, our aim is to find the optimum synthesis ...
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 ...
Synthesis and characterization of cobalt-substituted ferrite nanoparticles using reverse micelles
(2005-09)
With the objective of developing a magnetic nanoparticle based sensor, we have
synthesized cobalt-substituted ferrite particles using reverse micelles. Reverse micelles
have been used to control the nanoparticle size. ...
Optimization of a fluid bed dryer by the implementation of a model predictive controller
(2006)
Optimization of the drying operation requires a model containing the operating variables for fluid bed dryers (FBD). Modeling of FBD is still uncertain since the drying process is unpredictable and relies on empirical ...
