Nuclear power is a crucial source of clean energy for India. In the near-term, India is focusing on thermal reactors using natural and enriched uranium. In the long-term, India is exploring various options to use its large thorium reserves. India’s present nuclear installed capacity is 5680 MW, which contributes to about 3.4% of the annual electricity generation. However, nuclear power is an important source of energy in India’s aspirations for energy security and also in achieving its Intended Nationally Determined Contributions (INDC), of 40% fossil free electricity, by 2030.

"This paper demonstrates the benefit of conducting analyses of methods with the aid of a theory Such an approach provides a clear basis for analysing different methods that could in turn be compared with each other. This approach is demonstrated through the critical analysis of advanced systematic inventive thinking (ASIT) – a practical method – using the C–K theory, a design theory that offers a formal model of creative thinking. The analysis uncovers a paradox in ASIT operation: being creative while ‘staying in the box’.

We simulate substitution of various elements (X = Be, Mg, Al, Ga, Si and Ti) for Co using first-principles density functional theory and predict changes in its electrochemical potential. While the electrochemical potential of LiCoO2 is enhanced with substitution of Be, Mg, Al and Ga for Co, an opposite effect is predicted of Si and Ti substitution.

A detailed methodology to design the size of solar field for a parabolic trough plant is not explicitly available in open literature, particularly if thermal storage and hybridization are also considered, as most of the papers present a gross overview.

Solar Tower technology has gained considerable momentum over the past decade .Unlike the parabolic trough, Solar Tower has a lot of variants in terms of type of receivers, working fluids, power cycles, size of heliostats, etc .Most of the literature available on this technology does not address in great depths, details of various parameters associated with tower technology.The role and significance of this technology is brought out in the context of the Jawaharlal Nehru National Solar Mission (JNNSM) in order to achieve grid-connected solar power.

Will rising sea levels cause mass migrations of people from low-lying, impoverished equatorial areas into regions of higher ground—and if so, what will their reception be by their hosts? What can world leaders do to prepare for the population shifts likely to come from sea level rise already under way from the current high levels of carbon dioxide in the atmosphere?

Olivine silicates LiMSiO4 (where M = Mn, Fe, Co, and Ni) are promising candidates for the next generation of cathode materials for use in lithium ion batteries (LIB). Among these compounds, LiFeSiO4 is an attractive choice due to its low cost, environmental friendliness, high safety, and stability In this work, we use first-principles density functional theory-based calculations to determine the structural and electrochemical properties of olivine-type LiFeSiO4 and LiFe05M05SiO4 (where M = Mg or Al). 

Sodium-ion battery (NIB) cathode performance based on ammonium vanadate is demonstrated here as having high capacity, long cycle life and good rate capability. The simple preparation process and morphology study enable us to explore this electrode as suitable NIB cathode. Furthermore, density functional theory (DFT) calculation is envisioned for the NH4V4O10 cathode, and three possible sodium arrangements in the structure are depicted for the first time.
