Studies in the production of Micro organisms
The importance of the type of nitrogen in relation to the production of microorganisms of high catalytic power is emphasized. The dependence of the more appropriate and more closely related forms of nitrogen, in ... -
Systems-level modelling of hepatitis C virus Infection and treatment response
Hepatitis C Virus (HCV) infection affects approximately 130-170 million people worldwide. Interferon-based treatment, the current standard of care, fails to cure a significant fraction of patients. The cause of this treatment ... -
Testing the hypothesis of quorum sensing in vibrio fischeri : luminescence, motility, and biofilm
The individual behavior of prokaryotic organisms such as bacteria often gives rise to complexity typically associated with multicellular systems. The transition from unicellular to multicellular behavior occurs in response ... -
Studies on slurry reactors
Bubble column slurry reactors (BCSRs) are used for three phase contacting in petroleum, petrochemical, and chemical industries and in pollution control. The main objectives of the present work are: to analyse and evaluate ... -
Selective ion exchangers crosslinked poly (4-vinyl pyridine) with transition metal ion
Chelating resins are generally used to remove transition metal ions selectively. They are of two types: functionalised resins and templated resins. The selectivity in the former case is dependent on the pH of the medium, ... -
Studies in a trickle-bed reactor
Trickle bed reactors are widely used in petroleum industries and to a limited extent in chemical industries. In these reactors, a liquid reactant (or a liquid containing a reactant) trickles over a fixed bed of catalyst ... -
Stuides on slurry reactors
Bubble column slurry reactors (BCSRs) are used for three phase contacting in petroleum, petrochemical, and chemical industries and in pollution control. The main objectives of the present work are: to analyse and evaluate ... -
Analytical and numerical modeling of rarefied gas flows
Most geological flow and transport models describe the flow and convective-dispersive spreading of one or more components entirely dissolved in the most common geological fluid, water. However, many other processes—such ... -
Catalytic Degradation of Polymers
The effect of various catalysts such as TiO?, cobalt Fischer–Tropsch catalyst, and AlCl? was studied on the thermal degradation of various polymers including poly(vinyl chloride) (PVC), polystyrene, and polybutadiene, both ... -
Modeling and simulation of mammalian cell culture in hollow fiber bioreactors
In vitro culturing of mammalian cells is indispensable for the production of a large number of valuable products with potential medical applications. The fastidious nature of these cells, however, imposes several restrictions ... -
Enzymatic reactions in supercritical carbon dioxide
Lipases are enzymes that are widely used to catalyze a variety of industrially important reactions. However, lipase-catalyzed reactions are heterogeneous and are mass-transfer limited. Therefore, in most cases, the rates ... -
Studies on polymer anchored and homogeneous catalysis : liquid phase selective oxidation of styrene to benzaldehyde by wilkinson catalyst
Wilkinson catalyst [tris(triphenylphosphine)chlororhodium(I)] finds extensive application in liquid-phase organic reactions, but its industrial applications are severely restricted by the impracticality of economically ... -
Physico-chemical problems relating to the plant required for the manfacture of acetic anhydride from acetone Part I : Thermal cracking of acetone to ketene
Various processes fo r the manufacture of a ce tic anhydride today are by oxidation of acetaldehyde, pyrolysis of a cetic Pie. acid and pyrolysis of acetone. Of these,/^acetone-cracking process seems to be the most economic ... -
Selective ion exchangers crosslinked poly(4-vinyl pyridine) with transition metal ion as
Chelating resins are generally used to remove transition metal ions selectively. They are of two types: functionalized resins and templated resins. The selectivity of functionalized resins depends on the pH of the medium, ... -
Studies in reaction fundamentals of cracking and aromatization of hydrocarbons

Electrochemical - Morphological Evolution of the Positive Electrode in Autonomous Soluble Lead Redox Flow Batteries
The world is witnessing a transition where reliance on renewable energy is increasing. As of 2025, the renewable electricity capacity has risen to roughly 5000 GW (from 2000 GW in 2010). This progressive growth is to be ... -
Flexible Nanostructured Hydrogen Sensors
Hydrogen is rapidly emerging as a key energy carrier and industrial feedstock in the global transition to cleaner energy systems. However, due to its high diffusivity and flammability, even minor leaks can result in ... -
Thermodynamic properties of p-xylene - chloroethans
The importance of accurate thermodynamic data of pure substances and mixtures in research and industry hardly needs any emphasis. Apart from their utility in process design calculations, such data are useful in theoretical ... -
studies on oxidation of anthracene
Anthraquinone is an important dye intermediate. The demand for anthraquinone in India is likely to go up in the next few years, making its manufacture promising. Among the various methods, vapour phase catalytic oxidation ...
