Non-catalytic Synthesis of Biolubricant Esters and their Solubilities in Supercritical Fluids
Breakdown products released due to increased loss of mineral oil based lubricants to the environment lead to aquatic toxicity and release of harmful volatile compounds into the atmosphere. The production of these conventional ... -
Molecular Simulation Studies of Competing Pathways in Crystal Nucleation
Microscopic nature of nuclei and extremely fast nucleation events makes it difficult to study nucleation experimentally. Route to nucleation can be effected by different parameters such as thermodynamic conditions, uid ... -
Improved Theory of Clathrate Hydrates
(2018-07-30)The current theoretical understanding of thermodynamics of clathrate hydrates is based on the van der Waals and Plattew (vdWP) theory developed using statistical thermodynamics approach. vdWP theory has been widely used ... -
Computational Study of Stokesian Suspensions using Particle Mesh Ewald Summation
(2018-07-18)We consider fast computation methods for simulation of dynamics of a collection of particles dispersed in an unbounded Stokesian suspension. Stokesian suspensions are of great practical interest in the manufacturing and ... -
Swelling and Dye Adsorption Characteristics of Superabsorbent Polymers
(2018-07-18)In the current study, SAPs of cationic monomer [2 - (Methacryloyloxy) ethyl] trimethylammonium chloride have been prepared by free radical solution polymerisation with different crosslinkers. They were subjected to repeated ... -
Unraveling the Evolutionary Advantages of Crosstalk Between Two-Component Signalling Systems of M tuberculosis
(2018-05-29)M. tuberculosis (Mtb) senses and responds to changes in its environment primar-ily through two-component signalling systems (TCSs). Each TCS contains a trans-membrane histidine kinase (HK ) protein and a cytoplasmic response ... -
Multi-scale Modelling of Lamellar Mesophases
(2018-05-25)Surfactants are amphiphilic molecules which self-assemble at the interface in oil-water-surfactant mixtures such that the hydrophobic part, called tail, stays in oil and the remaining part, called head, resides in hydrophilic ... -
Modelling How Refractoriness to Interferon Compromises Interferon-Free Treatment of Hepatitis C Virus Infection
(2018-05-25)Hepatitis C virus (HCV) infection globally affects 130-150 million people. It causes both acute and chronic infections. Due to the severe side effects and low success rates of interferon based treatments, which formed the ... -
Stochastic Models Suggest Guidelines for Protocols with Novel HIV-1 Interventions
(2018-05-25)The treatment of human immunodeficiency virus (HIV-1) infection faces the challenge of drug resistance. The high mutation rate of HIV-1 allows it to develop resistance against all available drugs. New mechanisms of ... -
Studies in Water Treatment : Defluoridation using Adsorption, Denitrification using a Microbial Fuel Cell, and Contaminant Removal using Solar Distillation
(2018-05-23)This thesis includes both experimental and modelling studies on the treatment of drinking water. Three aspects were studied: (i) removal of fluoride (F– ) by adsorption, (ii) removal of fluoride and other contaminants by ... -
Molecular Simulation Study of Electric Double Layer Capacitor With Aqueous Electrolytes
(2018-05-22)Electric double layer capacitors (EDLCs) are an important class of electrical energy storage devices which store energy in the form of electric double layers. The charging mechanism is highly reversible physical adsorption ... -
Modeling Human Immunodeficiency Virus Transmission and Infection
(2018-05-21)HIV-1 is a global pandemic with about 39 million people infected. In India, 2.9 million people are infected and about 2 lakh new infections have been reported last year. To date, there is no cure for HIV/AIDS. Current ... -
