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 ...
Design of composite protein microcrystals for the sustained oral delivery of antigens
(2015)
Oral immunization is a promising method to decrease access of allergens and pathogens to the body. Oral delivery of antigens is challenged by the anatomical conditions of the gastrointestinal tract, such as degradation by ...
Optimization of drying-end-points measurements for the automation of a fluidized-bed dryer using FT-NIR sprectroscopy
(2004)
Automatic control of a fluidized-bed drying process depends on the availability of
an in-line sensor to provide accurate measurements of product moisture content. Nearinfrared
(NIR) spectroscopy technology provides a ...
Automation of a fluid bed dryer using multi-variant near infrared spectra and model predictive control
(2010)
The Fluidized Bed Dryer (FBD) is a common unit used in the pharmaceutical industry for its unique advantages when working with powders. With recent development in technology and environmental awareness, a desire to optimize ...
Evaluation of NIR, FTIR and Raman spectroscopies as monitoring techniques for recombinant GFP protein production in fed-batch cultures of Escherichia coli
(2008)
The expression of green fluorescent protein (GFP) was induced and monitored in fed-batch cultures of a genetically-engineered Escherichia coli strain. This recombinant E. coli is commercially available (Bio-Rad pGLO kit), ...
A new mixing rule in the modeling of the solubility of solids in supercritical fluids
(2006)
Currently, supercritical-fluid technology in the pharmaceutical and microelectronics industries is increasingly applied to solve difficult processing problems. The solubility of a solute in the supercritical fluid is the ...
Oil accumulation via Chlorella species using carbon sources from waste
(2009-12)
One of the global issues acquiring significant attention these days is related to energy supply and demand. The irreversible decrease of fossil fuels left to supply energy and the greenhouse gases increase in the atmosphere ...
Advanced process control of a fluid bed dryer granulator using near infrared sensing technology: An educational tool
(2020-12-11)
In this work, the design of an advanced process control strategy for a batch fluid bed dryer was achieved. This accomplishment will become an educational tool for the Center for Pharmaceutical Development and Learning ...
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 ...
