Reverse micelles in supercritical carbon dioxide for pharmacological applications: a spectroscopic characterization
(2004)
The aim of this research is to characterize microemulsions in supercritical (sc) CO2 using two spectroscopic techniques (UV-Vis and FT-IR) and apply the microemulsion approach to extract impurities from a pharmacological ...
Kinetic, intracellular ATP growth and maintenance studies, and modeling of metabolically engineered Zymomonas mobilis fermenting glucose and xylose mixtures
(2006)
Intracellular adenosine-5’-triphosphate (ATP) levels were measured in a metabolically engineered Zymomonas mobilis strain 8b over the course of batch fermentations of glucose and xylose mixtures. Recombinant Z. mobilis, a ...
Studies of ferrite based magnetic nanoparticle uptake and magnetocytolysis effects on model cell cultures
(2009)
Suspended ferrite magnetic nanoparticles are known to dissipate energy under an oscillating magnetic field. Such energy dissipation could be employed to locally raise temperature inside a tumor to 41-45°C (hyperthermia), ...
Rheology and gelation of physical polymer gels
(2011)
The discovery of new potent and water-insoluble drugs has emphasized the need for novel drug-delivery systems and personalized dosification. Biopolymers solutions are an alternative over conventional methods since they can ...
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 ...
Atomic pair distribution study of the growth of Pt nanoparticles in zeolites
(2016)
The Pair Distribution Function (PDF) is a total scattering method used to study the local structure of a material and yields a function in real space with peaks that represent the interatomic distances. In this work, we ...
Magnetically and thermally responsive nanoparticles for biomedical applications.
(2013)
The synthesis of magnetic nanoparticles which respond to alternating magnetic fields by Brownian and Neel relaxation mechanisms are of great interest in determining mechanical properties of complex fluids in the size scale ...
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 ...
