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 ... -
Study of Phase Equilibria and Interfacial Properties of Systems Containing Clathrate Hydrates Using Molecular Simulations
Gas hydrates, also known as clathrate hydrates are nonstoichiometric and crystalline solids composed of water and gas molecules. If the gas molecules are natural gas components, such as methane, ethane, propane, etc., ... -
Methodologies for Risk Assessment of Landslides Induced by Rainfall and Earthquake
Landslide is one of the greatest natural catastrophes and poses a major threat to lives and property worldwide. As development expands into unstable hill areas under the pressure of increasing population and urbanisation, ... -
