Abstract : Bulk mixed metal oxide catalysts are used in industry for a number of oxidation processes. Some examples are iron-molybdate for methanol oxidation to formaldehyde and bismuth-molybdate for propylene ammoxidation to acrylonitrile. However the reason behind their activity and selectivity is still not well-understood. To address these fundamental questions spectroscopic and kinetic studies were undertaken to provide quantitative bulk and surface information.

Abstract : In underground coal gasification (UCG) a cavity is formed in the coal seam due to consumption of coal. The irregular-shaped cavity consists of three distinct zones: a spalled-rubble zone on the cavity floor a cavity roof at the top and a void zone between the two. During UCG the coal seam between the injection and production wells undergoes two distinct growth phases. In phase-I coal/char near injection well gets consumed and cavity grows in a vertical (radial) direction and hits the overburden.

Abstract: Collections of grains (such as sand food grains mineral ores) often exhibit fluid-like behaviour despite the obvious differences between macroscopic grains and fluid molecules. But there are qualitative differences in the details of their kinematic and stress response. The lecture will highlight the broad features of granular flows their importance to industrial processes and very briefly outline the continuum-mechanical models that describe them. Prof. Prabhu R.

Abstract: While the GDP of India is growing around 7-8%/year Indian Chemical Industry is growing around 10-11% per year.By Revenue Indian Chemical Industry is 3rd in Asea and 12th in the world. Chemical Industry encompasses Refining Petrochemicals Inorganic Chemicals Organic Chemicals Specialty Chemicals Pharmaceuticals Paints & Pigments Fertilizers etc.Author is attempting to bring to your notice the status of Operating Plants in above sectors Demand and New Projects in the offing Govt of India new initiative like PCPIR and likely growth in the year to come.

Abstract: Pharmaceuticals today are the biggest exports for India and we are globally regarded as THE place for producing economical safe and efficacious medicines. The past decade has seen a significant interest in development of biotherapeutic products. It remains to be seen if India can replicate its success with pharmaceuticals in this class of products. While the challenges in successful development and commercialization of these products are regulatory as well as scientific this talk will focus on the latter.

Abstract: From a view point of global sustainability tremendous efforts is being made by the synthetic chemist to develop non hazardous energy efficient and environmentally benign routes for industrially important compounds. Use of water as solvent reaction medium is helpful in the practice to green approach and sustainability. Micellar catalysis is currently a rapidly expanding area of research.

Abstract: The process of atomization often involves ejecting thin liquid sheets at high speeds from a nozzle that causes the sheet to flap violently and break-up into fine droplets. The flapping of the liquid sheet has been attributed for more than 70 years to sheet’s interaction with the surrounding gas phase. We present theory and experimental evidence to the contrary and show that the flapping is caused by the thinning of the liquid sheet as it spreads out from the nozzle exit.

Abstract: Acetaminophen (APAP) which is a widely used over-the-counter drug and considered safe and effective as an analgesic and antipyretic drug is associated with hepatotoxicity in overdoses. To study the effect of phytoextract for hepatoprotection APAP-induced toxicity model was hence established in vitro using HepG2 cell line which mimic parenchyma cells of human liver. Various concentrations of APAP were evaluated to establish the toxicity model.

Abstract: While the evolution of hydrogen gas is often a troublesome process accompanying electrodeposition this feature can be exploited to template the growth of highly porous surfaces. This process known as the dynamic hydrogen bubble template (DHBT) method can be utilised to create a wide range of macroporous films with nanostructured porous walls. This talk will discuss - Does this provide a platform for innovation to create new generation catalysis? This talk also discuss how other Nano-surfaces created for different applications.

Abstract: A central area of research in the soft matter community is in organic/organic hybrid materials with nanoscale inorganic particles. These materials have been focused on due to their promise of having synergistic thermal mechanical and optical properties relative to the pure materials.It is now accepted that the spatial distribution of the inorganic nanoparticles critically affect the properties of the resulting materials but a grand challenge is to control the spatial distribution of the inorganic hydrophilic nanoparticles in the organic hydrophobic polymer matrix.
