Comparative analysis of electrochemical properties of LiMO2, LiMSiO4 and LiMPO4 (M=Fe, Co and Mn): A first principles study

Polyanion based cathode materials are most promising candidates for lithium ion batteries due to low cost, safety, environmental friendliness, etc. We performed first principles based DFT calculations to understand the stability, charge transfer mechanism and electrochemical performance of olivine phosphates, silicates and its comparison with the transition metal layered oxides based cathode materials. We have computed the changes in oxidation states using Bader method of topological analysis and charge re-distribution by analysis of partial density of electronic states.

A microscopic view of ion solvation in aqueous and non-aqueous electrolyte solutions from molecular dynamics simulations

Molecular dynamics simulations were performed to understand the ionic association and its effect on the structure and dynamics of ion solvation shell in aqueous and non-aqueous electrolyte solutions (water and methanol). The simulation results show that the probability of ion pairing depends on the interplay between ion-solvent interactions on the one hand, and Coulomb forces between ion and its counter-ion on the other hand.

Affordable Housing in Urban India

This policy briefs about the problems in urban areas and proposes solutions some highlights are here: Problem Highlight:
• 65 million Indians live in slums or substandard housing
• Prohibitive costs of private housing projects make them unaffordable
Proposed Solutions:
• Bank loans for purchasing land for affordable housing
• Reduce land costs through higher FSI/FAR provision
• Lower registration charges
• Shorter approval cycle

Electric Buses in India: Technology, Policy and Benefits

The Bangalore Metropolitan Transport Corporation (BMTC) is a government organisation that operates the public transport bus service in Bruhat Bangalore Mahanagara Palike (BBMP) area and parts of the Bangalore Metropolitan Region (BMR). At present, BMTC is one of the better run bus transport systems in the country.Over the past decade, India’s cities have been witnessing an increasing trend in motorization with deteriorating air quality, and there have been calls to promote public transport as a way out of this gridlock.

Developing GIS tools for planning, mitigation and preparedness for large scale emergencies and disasters

Emergency and disaster management involves four stages: Mitigation (Planning), Preparedness, Response and Relief. Concerned authorities at different levels (central, state, district, etc.) play different roles and have different responsibilities in each phase of emergency and disaster management. GIS-based tools have been shown to be useful in the response and recovery phases of an emergency. In this paper, we propose how GIS-based simulation tools can be used in the Mitigation and Preparedness phases of emergencies and disasters.
