Purpose: The purpose of this paper is to know the institutions who are developing electronic theses and dissertations (ETDs) in India, and to compare the ETDs in India based on a predetermined parameter. Design/methodology/approach: The methodology used for this research paper was a descriptive method. The institutional web sites were browsed and searched to collect the data. A relevant literature review was also carried out to describe the current status and other relevant information. Findings: Institutional repositories are a concept gaining movement today. India is moving ahead in this direction and major education and research institutes have already created their own institutional repositories. In analysis and findings, a detailed report of the analysis of data collection and its subsequent interpretations are given. Practical implications: If anybody would like to develop ETDs they can this overview of all the previous developed ETDs in India. It will be helpful for planning, developing and implementing new ETDs. Originality/value: This type of research study has not made till now. It is very important to study current and different types of ETD projects in India and its status. The study of special subject repositories is important for the students, scholars and researchers as well as for the LIS professionals. © Emerald Group Publishing Limited.

Herein we report on the synthesis of a ternary polymer composite of graphene, carbon nitride, and poly(3-hexylthiophene) (G-g-C 3N 4-P 3HT) by a solvothermal method. The prepared polymer composite catalysts are characterized by TEM, XRD, FTIR spectroscopy, and photoluminescence techniques for their morphology, structure and photocatalytic efficiency. Graphene-loaded polymer composites of carbon nitride (g-C 3N 4) and poly(3-hexylthiophene) act as efficient photocatalysts for waste water treatment. Methylene blue is used as the model pollutant and the rate of its photocatalytic degradation with G-g-C 3N 4-P 3HT is three times higher than that achieved with a g-C 3N 4-P 3HT composite. © 2012 WILEY-VCH Verlag GmbH & Co.

Earlier studies indicate that genotyping of Mycobaterium leprae based on single-nucleotide polymorphisms (SNPs) is useful for analysis of the global spread of leprosy. In the present study, we investigated the diversity of M. leprae at eight SNP loci using 180 clinical isolates obtained from patients with leprosy residing mainly in Delhi and Purulia (West Bengal) regions. It was observed that the frequency of SNP type 1 and subtype D was most predominant in the Indian population. Further, the SNP type 2 subtype E was noted only from East Delhi region and SNP type 2 subtype G was noted only from the nearby areas of Hoogly district of West Bengal. These results indicate the occurrence of focal transmission of M. leprae infection and demonstrate that analysis by SNP typing has great potential to help researchers in understanding the transmission of M. leprae infection in the community. © 2013 European Society of Clinical Microbiology and Infectious Diseases.

India is one of the largest producer and exporter of dyestuff among developing countries. Large amount of dyes is lost in industrial effluents during production and industrial use. Persistence of dyes in the environment, their non-biodegradability and toxicity necessitate urgent steps to develop environment-friendly approaches to remove them from wastewaters. The present work describes attempts to use iron-based catalytic nanoparticles (NPs) for removal and degradation of Acid Black 1, one of the notoriously toxic dyes. A rapid screening assay was developed in order to select NPs possessing reducing properties. Methylene blue (MB) dye (0.1mg/L, 250μl) was exposed to different preparations of NPs (7mg) for 30 minute in a 96-well microtiter plate and read at 630 nm using an ELISA reader. Iron sulphide nanoparticles (FeSNPs) stabilized by a plant biopolymer (BP) could remove >95% MB and were selected for further studies. The FeSNPs could remove Acid Black 1 efficiently (73.8%) with specific dye removal capacity of 19.7 mg/g NPs. FeSNPs were immobilized in alginate beads (average diameter 3.45 mm) and packed in polypropylene columns (22.5 cm long, 3 cm i.d.) having bed volume of 42 ml. Acid black 1 solution (20 mg/L) was passed through the columns at predetermined flow rates in up-flow mode using peristaltic pump. The mass transfer kinetics were favourable at a flow rate of 2.2 ml/min (mass transfer coefficient 9.38×10-5 L.mg-1.min-1), and 120 bed volumes of the solution could be treated with efficiency exceeding 90%. Analysis of column effluent by UV-visible and FTIR spectroscopy revealed that removal of dye from solution was due to reductive degradation. © (2013) Trans Tech Publications, Switzerland.

Al3+ substituted lithium ferrites having general formula Li 0.5Fe2.5-xAlxO 4 with x = 0, 0.5, 1.0, 1.5 and 2.0 were successfully synthesized by the chemical method. The starting materials used for this method are the metal nitrates and Urea (NH2CONH2) as fuel. This method involving exothermic reaction is popularly known as combustion method. X-ray diffraction and infra red spectroscopy is used to confirm the formation of the compounds. The room temperature electrical conductivity of these compounds is found relatively low which is attributed to the low loss of lithium during preparation. As expected the conductivity and Curie temperature (Tc) of these compounds is found to decrease with Al3+ substitutions. The μβ determined from hysteresis loop studies matches fairly with that of the calculated from presumed magnetic structure based on cation distribution and using the Neel's model. © 2014 Elsevier B.V.
