Effect of various pesticides (insecticides, fungicides and herbicides) has been studied on growth and efficiency of symbiotic properties of 3 fast growing Rhizobium sp. under green house conditions. The results revealed adverse effects on plant growth and nitrogen fixing capacity as measured by dry weight and total nitrogen content of plants infected with pesticide treated Rhizobium. Of the pesticides tested, herbicides were found to be more effective on the above parameters than the insecticides and fungicides.

Green chemistry is playing an important role for synthesizing organic compounds, due to its eco-friendly nature and low cost. In green chemistry, metal nanoparticles exhibited some useful physical and chemical properties （catalytic activity）. Due to its diverse properties, nanoparticles can be utilized as a catalyst in various organic reactions. Recent research has been directed towards the utilization of eco- friendly and bio-friendly plant materials in nanoparticles synthesis. In our present work, TiO2 nanoparticles （TiO2 NPs） were synthesized using Annona squamosa peel extract and their catalytic applications were studied on the 2,3-disubstituted dihydroquinazolin-4（l1H）-one synthesis. Synthesized compounds were confirmed using FT-IR.1H NMR, 13C NMR and GC-MS analyses.

Diversity,population structure and regeneration status of arboreal species in the four sacred groves of Kushalnagar,Karnataka

Journal of Forestry Research 2017年第2期28卷 357-370页

作者： Shwetha.bharathi A.G.Devi Prasad Department of Studies in Environmental Science Universityof MysoreManasagangotriMysoreKamataka 70 006India

Assessment of tree species diversity, structure and regeneration status of four sacred groves of Kushalnagar,southern Karnataka was carried out. The random quadrat method was employed in each grove for enumeration of tree diversity and regeneration status. A total of 98 tree species belonging to 38 families were found from the sampled *** groves possess higher diversity and basal area. Some67 % of species have shown regeneration, while 17 % of species had no regeneration. Another 15 % of species were reappearing or immigrating. It is observed that increased disturbance was directly proportional to number of reappearing or immigrating species and inversely proportional to the diversity in all the sacred groves. Significant impact on diversity, species richness and regeneration status of the flora due to manifold anthropogenic activities have been recorded.

Research progress and challenges of two dimensional MoS_2 field effect transistors

引用

Journal of Semiconductors 2018年第10期39卷 23-33页

作者： N Divya.bharathi K Sivasankaran School of Electronics Engineering VIT University

This review paper gives an outline of the recent research progress and challenges of 2D TMDs material MoS2 based device, that leads to an interesting path towards approaching the electronic applications due to its sizeable band gap. This review presents the improvement of MoS2 material as an alternate to a silicon channel in a transistor with its excellent energy band gap, thermal conductivity, and exclusive physical properties that are expected to draw attention to focusing on semiconducting devices for most futuristic applications. We discuss the band structure of MoS2 for a different number of layers with its structure, and various synthesis techniques of the MoS2 layer are also reviewed. The MoS2 based field effect transistor has attracted a great deal of attention due to its excellent properties such as mobility, on/off current ratio, and maximum on-current of the devices. The transition of mobility as a function of temperature and thickness dependence are also discussed. However, the mobility of MoS_2 material is large in bulk form and lower in monolayer form. The use of a high-k gate dielectric in MoS2 FET is used to enhance the mobility of the device. Different metal contact engineering and different doping techniques were deployed to achieve low contact resistance. This review paper focuses on various aspects of layered TMDs material MoS2 based field effect transistors.
