Sodium-ion batteries are the commercially and environmentally viable next-generation candidates for automobiles. Structural and electrochemical aspects are greater concerns towards the development of a stable cathode material. Selecting transition metals and their composition greatly influences charge order, superstructures, and different voltage plateaus. This, in turn, influences transport properties and cyclic performance. This article aims to study the electrochemical performance, diffusivity, and structural stability of Na x [M y Mn1−y ]O2 (M = Fe, Ni) as cathode.

In Central Receiver Systems (CRSs), thousands of heliostats track the sunrays and reflect beam radiation on to a receiver surface. The size of the reflected image and the extent of reflection from the heliostats are one of the important criteria that need to be taken into account while designing a receiver, since spillage losses may vary from 2 to 16% of the total losses. The present study aims to determine the size of an external cylindrical receiver, such that the rays reflected from all the heliostats in the field are intercepted. 

This study was commissioned by Karnataka Electricity Regulatory Commission (KERC) to identify key implementable strategies for the state of Karnataka for achieving the objectives of 24x7 Power for All The study describes the power supply scenario in the State including estimates for future energy demand The status of 24x7 power supply is analysed along the dimensions of access (electrification), adequacy (per capita consumption), affordability (cost of supply), availability (duration of supply), and reliability Future plans for generation capacity are analysed to determine the range of fore

A report of the 24th Annual General Meeting of THE Materials Research Society of India (MRSI)

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

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

A presentation on storage options and materials for renewable energy applications

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
