Molecularly Imprinted Polymers for the Recognition of Tobacco Viruses

Abstract :-
The goal of this research is to elucidate the mechanism of virus recognition in molecularly imprinted polymers (MIPs) using already utilized techniques. The clinical relevance of this study relates to the development of a virus imprinted MIP, which would apply to the identification, classification, and removal of viruses. The separation of viruses and virus-like particles from various media represents an enormous challenge to the fields of medicine, healthcare, and biotechnology.

Impact of Stochasticity on Gene Regulation Networks

Abstract :-
This study is done using impact of stochasticity on gene regulation networks, using the cell-to-cell communication mechanism in Escherichia coli as an example. First we explored signal mediated positive autoregulation networks and their stochastic bistability, in the presence of which an initially homogeneous cell population would evolve into two distinct subpopulations. We proposed the simplification of the full network into one that can be theoretically studied. Simulation results indicate the simplifications retain the bistability and the distribution shapes so that the simplified network can be used to predict the bistable behavior of the full network.

Adsorption of CO2 on Indian Coals

Abstract :-
CO2 sorption studies were conducted for Raniganj coals of India from the point of view of CO2 adsorption & desorption and the effect of temperature, coal particle size and media pH. Adsorption and desorption studies were conducted for 4 samples with the highest adsorption capacity reported as 11.09mL/g of coal and lowest as 5.15mL/g at 30°C.Desorption studies revealed the existence of both positive and negative hysteresis curves.

CFD Modeling of Hydrodynamics of Fluidized Bed

Abstract :-
The objective of this project is to simulate a gas-solid fluidized by applying CFD techniques in order to investigate hydrodynamics and heat transfer phenomena. Reactor model predictions will be compared with the corresponding experimental data reported in the literature to validate the model . To simulate a gas-solid fluidized bed we need to use the multiphase flow approach. Continue reading CFD Modeling of Hydrodynamics of Fluidized Bed

CFD Simulations for Scale Up of Wet Milling in High Shear Mixers

Abstract :-
In this work, CFD results at different scales are used to aid in the scale up of crystal wet milling processes. CFD simulations were performed to simulate different scale mixers. In addition, wet milling studies were conducted at the bench scale to complement the CFD results and predict wet milling performance in larger scale mixers. The flow properties in a batch Silverson L4R rotor-stator mixer at 4000 and 6000 rpm were investigated. A hybrid technique was developed. The new method is computationally efficient compared with the standard sliding mesh method. Continue reading CFD Simulations for Scale Up of Wet Milling in High Shear Mixers

Butanol Production from Glycerol by Clostridium Pasteurianum

Abstract :-
The fluctuations in oil prices have stimulated the production of renewable biofuels, in particular the production of bioethanol and biodiesel. The production of biodiesel has expanded almost six fold in the past years. The ten wt% of the biodiesel process results in crude glycerol. Once a valuable product, nowadays glycerol is considered a waste and a surplus material. Its current low price makes it an attractive substrate for a fermentation process. Molecular genetics have unveiled new insights about solvent production in Clostridia. It has been recognized that endospore development and solvent formation share a regulatory mechanism.
