We have developed a novel isonicotiamide-based fluorescent "turn-on" chemosensor 1 for the selective detection of Zn2+ and HSO4 -. The sensor 1 can detect Zn2+ and HSO4 - with a detection limit down to the nanomolar level by forming a complex in 1-1 stoichiometry in the presence of other anions and 2-1 in presence of cations in aqueous solution. Density functional theory calculations on 1 and the 1-Zn2+/HSO4 - complexes are consistent with the experimental results. We have successfully utilized the above cation and anion for the fabrication of INHIBIT molecular logic gates. Furthermore the receptor 1 successfully detected the Zn2+ and HSO4 - ions in HeLa cells cultured in Zn2+ and HSO4 - enriched medium. © 2016 The Royal Society of Chemistry.

Wolbachia are maternally inherited endosymbionts found in wide range of arthropod hosts. They alter host sex biology by various phenotypic effects. This is making them as an emerging novel biological tool to control the insect pests. Indian Leaf worm, Spodoptera litura is one of the most devastating pests which cause severe damage to various crops resulting in serious economic loss. Application of chemical insecticides is an extensive practice to control this pest. It develops resistant to various chemical pesticides. Microbial control by a nuclear polyhedrosis virus (SpltMNPV) and entomopathogenic nematodes are available against this pest. However, it has various limitations. The objective of the present study is to explore Wolbachia infection in S. litura. In the present study a novel Wolbachia strains from S. litura population has been detected which is further characterized by multigene approach for the first time. Phylogenetic affiliation revealed that this strain is belonging to B supergroup and completely different from those which are already reported for S. litura and S. exempta. This finding further lays a platform for possible use of this Wolbachia strain in biological control of S. litura.

Herein, we reported our studies related to structural elucidation and gas-phase fragmentation patterns of the imidazolium and pyridinium based ionic liquids, using a positive ion electrospray ionization triple quadrupole mass spectrometry. Ionic liquids mainly imidazolium/ pyridinium/alkylammonium salts, possess properties due to which there are many applications from the point of view of green chemistry. The recorded mass spectral patterns are presented and possible pathways for fragmentations are suggested. The mass spectrum of tetrabutylammonium bromide and its fragmentation pattern is discussed since we used this compound as a template in the synthesis of ionic liquids. Our analysis also suggests possibilities of associations of ions in the form of C 2A+ species in vapour phase for the studied ionic liquids.

JalaSRI - Watershed Surveillance and Research Institute is a district level initiative to address conservation and sustainability related issues in Jalgaon district. Here, we outline JalaSRI's efforts for developing knowledge base on biophysical features of landscape and socio-economic situation of local people in Jalgaon district. This has been referred as first step towards initiating egovernance for biodiversity conservation and promotion of good agricultural practices in the district. With the use of latest developments in remote sensing, GIS and Sensor Technology, we monitor ecological status of the district. The multi-sectoral and multi-scalar approaches adopted by JalaSRI are the key to success to such initiative. JalaSRI provides platform to professional, academia and local stakeholder and facilitate two way communications between government and local user community. This helps converge the available scant resources and maximise the benefits of governmental schemes at grass root level, which is the ultimate goal of e-governance. Copyright 2011 ACM.

An efficient one pot synthesis of ionic liquids (ILs) employing molten salt as a solvent is described. The imidazolium salts and pyridinium bromide and other heterocyclic compounds were synthesized using tetrabutylammonium halides as ionized solvents when melt. The yields were good and compounds were confirmed by their mass and spectral data. The utility of the method as a green one is suggested by comparing yield and kinetic time requirements with other known well established methods.
