With the awakening of Climate Change as the biggest challenge of mankind which generates the dilemma or trade off between growth and environmental sustainability, this paper finds its explanation in the notion sustainably as prescribed by Gandhian Economics. While tackling the environmental concerns, the developing countries need a policy framework which supports the structural transformation of their energy system towards renewable energy sources. Given the bottlenecks of lack of capital. Innovative capacity , other multitude problems like unemployment, poverty etc. prevailing in all developing countries like India, energy transition towards renewables become a challenge. This is another concern of developing economies which again finds its unfolding in the principles prescribed by Gandhian notion of self–reliant and self sufficient decentralised communities. As a result the paper successfully establishes the foundation of Gandhian thought , Gandhian Economics and Gandhian perspective as a key instrument to visualize the process of energy transition in growing economies like India.<br><br>","PeriodicalId":433656,"journal":{"name":"MatSciRN: Energy Storage (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131269148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Out of basic needs of human which include food, drinking water, energy, cloth, shelter, health and clean environment, perhaps, solving energy problem by providing a way to generating, storing, and converting it to required form at any time and any amount of time called ‘ubiquitous energy’ is the opportunity and the challenge for scientific world and for human prosperity. In this paper, we have discussed the challenges and opportunities of nanotechnology innovations and business opportunities in energy sector. The nanotechnology impact on seven areas of energy sector including solar energy, wind energy, nuclear energy, oil-fuel based energy, artificial photosynthesis, energy storage and effective energy management to promote nanotechnology based energy as ubiquitous energy are discussed and reviewed.The paper includes possible innovations and research opportunities in nano-modified solar cells, Nano-influenced Fuel storage cells, and nanotech based artificial photosynthesis. We have also used ABCD analysis to discuss the business opportunities by studying the advantages, benefits, constraints and disadvantages of nanotechnology based energy solutions. Finally, a futuristic possible solution is proposed for the problem of how to solve ever demanding energy crisis using Molecular Nanotechnology model.","PeriodicalId":433656,"journal":{"name":"MatSciRN: Energy Storage (Topic)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123812011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, TiO 2 emulsion is used as a solvent of binder in the preparation of graphite anode slurry. In this method, high-performance electrodes have been achieved by combining two graphite and TiO2 nanoparticles constituents into an integrated structure. TiO 2 emulsions with different concentrations of 10%, 20%, and 100% are applied to prepare the binder solvent. The graphite anode made with 10% concentration of TiO 2 emulsion (NG-T10) shows the best performance in comparison with other samples. The Nano-scale images of the scanning electron microscope (SEM) affirm the existence of a uniform coating on the surface of the natural graphite particles for the NG-T10 electrode. Energy-dispersive X-ray (EDX) spectroscopy on the NG-T10 sample clearly indicates the Ti element signal. According to atomic force microscopy (AFM) images, an increment in surface roughness can provide a more effective surface and improve wettability, resulting in better electrochemical performance of NG-T10. The charge-discharge test of the NG-T10 half-cell represents an excellent cycle performance without any capacity degradation during 100 cycles at 0.5 C. However, the value of capacity retention for bare natural graphite (BNG) is 90.7% in the same conditions. The electrochemical impedance spectroscopy (EIS) results indicate that the existence of TiO 2 nanoparticles in NG-T10 improves the resistance of SEI film and charge-transfer resistance. The NG-T10 also enhances the pouch cell capacity at various current densities up to 4 C.","PeriodicalId":433656,"journal":{"name":"MatSciRN: Energy Storage (Topic)","volume":"9 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123738892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A single-buck converter interfaces a 2 kW PV array and DC load and ensures a good operation of the maximum power point tracking (MMPT) and battery charge control, simultaneously. For the MPPT side, an improved adaptable step size P&O approach is suggested to reach the real maximum power point (MPP) of the solar PV array under varying weather conditions with reduced steady-state oscillation and less power loss. Furthermore, a three-stage charging controller (TSCC) is used in the battery charge control side to charge a 200 Ah lead-acid battery. MATLAB/Simulink environment tool is used for the implementation of the overall PV system. The simulation results under different scenarios of weather conditions prove the highest tracking performances of the improved approach over the conventional P&O method. In this respect, the developed P&O approach can capture the MPP in a time less than 2 milliseconds, which is 10 times faster than the conventional P&O method. In addition, it can mitigate the power losses and reduce the oscillations around the MPP to half compared with the basic P&O method. Furthermore, the improved P&O approach with TSCC can significantly enhance the BS charging operation with good stability in the output power, voltage, and current of the battery.","PeriodicalId":433656,"journal":{"name":"MatSciRN: Energy Storage (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130814443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
