Analytical expression of the physical parameters of an illuminated solar cell using explicit J-V model
Analytical expression of the physical parameters of an illuminataed solar cell using explicit J-V model.Simple explicit model was introduced to represent the J–V characteristics of an illuminated solar cell with parasitic resistances
Design and development of efficient bi-functional catalyst by tuning the electronic properties of cobalt-manganese tungstate for oxygen reduction and evolution reaction
Solid‐state electrochemistry is drawing considerable interest as the interconversion of O2 and water playing an important role in energy conversion and storage technologies. With the aim of developing an efficient bifunctional catalyst by tuning the electronic properties and local structure around the 3d metal in CoWO4, solid solutions of Co1−xMnxWO4 are investigated. Nanocrystalline Co1−xMnxWO4 (x=0 to 1) phases with a unique exposure of low surface energy planes are synthesized by hydrothermal methods.
Nuclear Viewpoint in India
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.
A theoretical analysis of creativity methods in engineering design: casting and improving ASIT within C-K theory
"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’.
Tuning electrochemical potential of LiCoO2 with cation substitution: first principles predictions and electronic origin
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.
Methodology for sizing the solar field for parabolic trough technology with thermal storage and hydribization
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.
Challenges and opportunities for Solar Tower technology in India
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.
Sea level rise and climate change exiles: A possible solution
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?
