Development of an empirical model to predict the mean residence time in a tablet press feeder
(2017)
The die filling process is a continuous operation that is crucial to comply with the specifications and quality attributes of a pharmaceutical tablet. Die filling is usually performed using a rotary tablet press that has ...
Modeling and control of continuous tumble mixing of granular materials
(2005-06)
An approach to automatic control of a continuous tumble mixer of powders is presented. The control system is based on an ideal model that describes the mixer dynamics where the controlled variables are the outlet flow from ...
Improved binary and ternary nanostructured photocatalysts for gas phase detoxification of toluene
(2005)
Photocatalysis using nanocrystalline materials with enhanced catalytic properties under ultraviolet (UV) or visible light has the potential for becoming one of the leading processes for the abatement of environmental ...
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 ...
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 ...
Selective hydrodeoxygenation of biomass-derived oxygenates over heterogeneous Mo-based catalysts
(2021-07)
The development of catalytic pathways to produce commodity chemicals from lignocellulosic biomass is promising for substituting non-renewable fossil feedstock use. This dissertation studied the catalytic performance of ...
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 ...
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 ...
Analysis of reaction pathways on the catalytic conversion of CO2 using quantum mechanical calculations
(2015)
The greenhouse gas CO2 is an inexpensive and abundant feedstock that may be used to produce valuable organic compounds. The main goal of this work was to unravel reaction pathways for CO2 conversion through hydrogenation ...
