An Approach Towards Inactivation of Susceptible and Antibiotic Resistant Bacterial Contamination using Novel Photo–(electro)-catalysts
Water in most rivers in India does not meet the standards for drinking and even for bathing purposes due to the high concentration of coliforms, organic and inorganic contaminants. Overuse, uncontrolled release and careless ... -
Development Of Ionic Catalysts For The Water-gas Shift Reaction And Exhaust Gas Purification
(2013-04-04)Treatment of fuel cell feed H2 for the removal of CO is important owing to the poisoning of the catalysts, thereby affecting the performance of the fuel cell. Strong and preferential adsorption of CO over the catalyst takes ... -
Development of noble metal catalysts and detailed kinetic models for CO oxidation and water gas shift reactions
Noble metal (Pt, Pd, Rh) based catalysts have been highly effective for CO abatement applications such as CO oxidation and the water gas shift reaction (WGS). In the venture for development of novel catalysts, noble metal ... -
Experimental Determination And New Correlations For Multi-Component Solid Solubilities In Supercritical Carbon Dioxide
(2016-03-02)The fluids that are operated above their critical temperature and pressure are known as supercritical fluids (SCFs). SCFs replaces the conventional organic solvents in the chemical processes due to their attractive ... -
Generation, Characterization and Control of Nanoscale Surface Roughness
(2018-01-11)Surface roughness exists at many length scales-from atomic dimensions to meters. At sub-micron scale, the distribution of roughness is largely dependent on the process that generates the surface through the mechanisms of ... -
Inactivation of Microorganisms by Photocatalysis
(2018-02-20)Photocatalysis is an advanced oxidation process, which has shown to possess an enhanced capability to remove a wide range of contaminants. It involves the use of a semiconductor photocatalyst and a photon source. Photocatalysis ... -
Kinetics Of Photo Initiated Organic And Polymer Reactions
(2012-04-23)Photo-initiated reactions involve the use of ultraviolet (UV) or visible light radiation to effect chemical transformations. Some of the advantages of photo-initiated reactions over thermal or high pressure reactions include ... -
Kinetics of Photocatalytic Degradation of Dyes, Organics and Polymers using Nanomaterials
The main objective of this thesis was to investigate the application of photocatalysis for the degradation of organics, dyes, polymers, reduction of metal ions, decomposition of NO, etc. In this context, extensive work was ... -
Moisture Barrier Polymer Nanocomposites for Organic Device Encapsulation
(2018-07-10)The advancement in smart technologies for organic conducting polymers as flexible substrates in LEDs, PVs and solid state lighting necessitates the development of ultra-high barrier films to protect the devices from moisture ... -
Non-catalytic synthesis of biodiesel and solubilities of mixtures of lipid derivatives in supercritical fluids
The fossil fuels are depleting rapidly as the demand for energy and its allied chemicals is continuously increasing in the modern world. In addition, the concerns over climate change due to the greenhouse gases emitting ... -
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 ... -
Processing mediated polymorphism in PVDF-based dielectric polymers and their application
The ever-increasing demand in electronic devices, piezoelectric materials such as ceramics, polymers and polymer ceramic composites with enhanced piezoelectric and dielectric properties has become the focus of many ... -
Swelling and Dye Adsorption Characteristics of Superabsorbent Polymers
