Transition Metal Oxides as Cathodes for Li-ion battery: Structure, stability and substitution effects

First–principles DFT simulations are computationally demanding but are reasonably accurate in predicting properties of battery cathode materials. Properties relevant to selection of cathode
material include electrochemical potential, structural stability, energy/power density and cycle life etc. Computational screening of materials speeds up the process of material discovery by
saving on costs of experiments and time. In addition, it helps in developing correlation between properties and structural and chemical aspects. Here we analyze some of these aspects for the

A Sustainable Development Framework for India's Climate Policy: An Interim Report

As a large developing country, India’s challenge is to meet its development aspirations in a carbon-constrained world This study, undertaken by the Centre for Study of Science Technology and Policy (CSTEP) uses Sustainable Development (SD) as the overarching framework and aims at equitable access to energy, clean air and water, food, health and livelihoods and economic growth The study connects elements of SD in an integrated bottom-up approach to understand the implications for economy, energy trajectories, emissions and costs

Rare Earths Recovery from Secondary Resources: Opportunities, Challenges and Environmental impacts

Rare earths are not as rare as the name suggests, they are relatively abundant in the earth`s crust,
but their concentration is less in ore deposits, in particular heavy rare earths. Commercially,
REEs are extracted from the bastnasite, monazite and xenotime ores. The extraction of REEs
from mineral ore (primary source) is a complicated multi step process with a huge amount of
toxic wa ste released during the processes. The recovery of REEs from secondary sources such

Economics of Fast Breeder Reactors in the Indian Scenario

Fast Breeder Reactors (FBR) are expected to play a major role in India’s power program and help utilise the country’s large thorium (Th) reserves It is important to examine in detail all issues including economics, safety, and security In this study, we have evaluated the economics of electricity from FBRs We propose to examine safety and security aspects in a future work This report also compares the cost of electricity from PFBR with other sources including PHWRs
