The Indian School of Mines is an educational institute of India. It is located in the mineral-rich region of India, in the city of Dhanbad. It was established by British Indian Government on the lines of the Royal School of Mines - London, and was formally opened on 9 December 1926 by Lord Irwin, the then Viceroy of India. What started as an institution to impart mining education has now grown into a full-fledged technical institution of international acclaim offering a host of programmes like B. Tech., M. Tech., M. Sc. Tech., and MBA. ISM admits undergraduate students from the top rankers out of the 150,000 candidates appearing for Advanced Joint Entrance Examination which is the replacement of IIT-JEE.Indian School of Mines has 18 academic departments covering Engineering, Applied science, Humanities and Social science and Management programs with a strong emphasis on scientific and technological education and research in the areas of Earth science. The school has produced many pioneers of the Mining and Oil Industry, including Padma Bhushan awardees. ISM has been ranked consistently as one of the top 12 engineering institutions in India.

A detailed examination of lithostratigraphic, tectonothermal, geochronologic and palaeomagnetic database of the Dharwar-Bastar cratons of South India, the Yilgarn craton of Western Australia and the East Antarctic shield has shown broad similarity. Two palaeomagnetic key poles of ~. 2400. Ma age from the Dharwar and Yilgarn cratons suggest near neighbor positions. Matching patterns of craton outlines, orientation of mafic dyke swarms and palaeo-north direction for ~. 2400. Ma have established a continental assembly of "SIWA", an acronym for South India (SI) and Western Australia (WA), at ~. 2400. Ma. In this assembly the Yilgarn craton fits against the Bastar craton and the Singhbhum craton. The available geological data from the Napier Complex of the Eastern Antarctica and the Dharwar craton of South India were used to prepare the barcode style reconstruction of Archaean tectonostratigraphic events of both the cratons. The method of matching continental outlines, the internal features of two continental blocks and the palaeomagnetic data demonstrate that the Napier Complex was also a part of "SIWA" during the period 2200-1900. Ma and was located at the position of the Cuddapah basin of India adjacent to the Dharwar craton and the Yilgarn craton. The separation of the Napier Complex from the south Indian block led to the development of the Cuddapah basin at ~ 1950. Ma. © 2011 International Association for Gondwana Research.

Ga-pWSe2 Schottky diodes were fabricated on both uncleaved and cleaved WSe2 surfaces and were subjected to forward current-voltage-temperature measurements. The conduction mechanisms have been studied over a temperature range of 140 K-300 K. From and above 200 K onwards, the current-voltage characteristics of both diodes obey thermionic emission (TE) theory with Gaussian barrier height distribution. At temperatures below 200 K, the presence of generation-recombination (GR) and tunneling (TN) currents becomes noticeable. The observed anomalies at low temperatures were effectively interpreted in terms of the combined influence of TE, GR, and TN currents across the interface. Furthermore, the cleaved diode with less surface inhomogeneity showed better characteristics than the uncleaved diode. © 2011 IEEE.

Energy price is rising due to rapid depletion of fossil fuels. Development of renewable and non-polluting energy resources is necessary for reducing pollution level caused by those conventional fuels. Researchers have recognized hydrogen (H2) as such an energy source. Hydrogen is a potential non-carbon based energy resource, which can replace fossil fuels. Hydrogen is considered as the alternative fuel as it could be generated from clean and green sources. Despite many advantages, storage of hydrogen is a serious problem. Due to high inflammability, adequate safety measures should be taken during the production, storage, and use of H2 fuel. This review article elucidates production methods and storage of hydrogen. Besides this safety related to H2 handling in refilling station, and automobiles has also been discussed. Study shows that safety program and awareness could be fruitful for increasing the acceptance of hydrogen as fuel. © 2013 The Korean Society of Industrial and Engineering Chemistry.

Reconstruction of the Neoproterozoic supercontinent Rodinia shows near neighbour positions of the South Indian Cratons and Western Australian Cratons. These cratonic areas are characterized by extensive Paleoproterozoic tectonism. Detailed analysis of the spatio-temporal data of the Satpura Mountains of India indicates presence of at least three episodes of Proterozoic orogeny at ∼2100-1900 Ma, ∼1850 Ma and ∼1650 Ma, and associated basin development and closing. A subdued imprint of the Grenville orogeny (∼950 Ma) is also found in rock records of this Mountain Belt. The Capricorn Orogen of Western Australia also shows three episodes of orogeny: Opthalmian-Glenburgh Orogeny (2100-1950 Ma), Capricorn Orogeny (∼1800 Ma) and Mangaroon Orogeny (∼1650 Ma), and basin opening and closing related to these tectonic movements. These broad similarities suggest their joint evolution possibly in a near neighbour position during Paleoproterozoic Era. In view of juxtaposition of the Western Australia along the east coast of India, at the position of the Eastern Ghats, during Archean, it is suggested that the breaking of this Archean megacraton at ∼2400 Ma led to northward movement of the broken components and formation of the Satpura-Capricorn Orogen (at ∼2100 and ∼1800 Ma) due to the collision of cratonic blocks with the pre-existing northern cratonic nuclei of India and Western Australia. This is also the time of formation of the supercontinent Columbia. A phase of basin opening followed the ∼1800 Ma event, followed by another phase of collisional event at ∼1600 Ma at the site of the Satpura-Capricorn Orogen. Subsequent evolutions of the Satpura and the Capricorn Orogens differ slightly, indicating separate evolutional history. © 2011, China University of Geosciences (Beijing) and Peking University.

The Bastar Craton of India is composed of Archaean nuclei of tonalite-trondhjemite-granodiorite gneisses, enveloped by an older granite-greenstone belt (>3000 Ma) with banded iron formation (BIF), and an auriferous younger granite-greenstone belt with BIF. Available geological, geochemical and geochronological data indicate multiple episodes of orogeny with high-grade metamorphism at 3200-3300, 2600-2700, 2100-2200, 1900-2000, 1800-1850, 1500-1600 and 1400-1450 Ma, and continental rifting and basin development marked by emplacement of mafic dyke swarms at c. 2900 (subalkaline mafic dykes; BD-1A), 2480 (high-Mg mafic dykes; BD-1B), 2100 (Fe-tholeiite dykes; BD-2A), 1880 (Fe-tholeiites dykes; BD-2B), 1776 and 1422 Ma. Associations of extensive bimodal volcanics and riftogenic sediments are found in the Neoarchaean and Palaeoproterozoic basins of the craton. Evidence of Palaeoproterozoic (Huronian) glaciation and associated 'cap carbonate' followed by deposition of fine clastics with manganese ore is found in the Palaeoproterozoic Sausar Group. The lithological association of the Sausar Group is comparable to the carbonate-tillite association of the Huronian Supergroup, Snowy Pass Supergroup, Transvaal Supergroup and Turee Creek Group. The geological evolution of the Bastar Craton matches that of Western Australia and South Africa. Such similarities can be analysed to develop a unified Palaeoproterozoic assembly for these provinces. © 2015 The Geological Society of London.
