On the Structural, Optical and Magnetic Properties of MgO Nanobelts
Authors : N Rajamanickam,K Ramachandran,

Magnesium oxide (MgO) nanostructures were synthesized by hydrothermal method and investigated for the influence of temperature on the structural and optical properties. Morphological analysis by SEM reveals the formations of nanobelts (NB) and porous nanobelts (PNB). Optical properties were investigated by UV-vis and FTIR spectroscopy. The absorption spectra of MgO NBs and MgO PNBs exhibit a band...

Creation of Sub Wavelength Focal Spot Segment Using Longitudinally Polarized Multi Gaussian Beam
Authors : K Prabakaran,K.B Rajesh,V Hariharan,V Aroulmoji,P.M Anbarasan,A Mohamed Musthafa,

We investigated the focusing properties of a radially polarized multi gaussian beam through an annular high Numerical Aperture (NA) objective lens based on vector diffraction theory. It is observed that our proposed system can generate sub wavelength focal spot segment with long focal depth (26λ) is achieved. This kind of non diffracting focal segments is called as dark channel, which may have...

Geometrical, Electronic Structure, Nonlinear Optical and Spectroscopic Investigations of 2-Amino-6-Nitrobenzothiazole as Sensitizer for DSSC
Authors : D Sakthia,M Prakasam,A Prakasam,S Sivakumar,P.M Anbarasan,

In this work, the vibrational characteristics of 2-Amino-6-Nitrobenzothiazole have been investigated. The structure of the molecule have been optimized by density functional theory B3LYP method with 6-311++G(d,p) basis set. The Raman and infrared spectra have been simulated from theoretically calculated intensities; also theoretical and experimental vibrational data confirms the presence of...

Preparation and Characterization of Nanostructured Ni Doped MnO2 Electrodes for Electrochemical Supercapacitors
Authors : R Gobi,R Poonguzhali,N Shanmugam,G Viruthagiri,A Senthilkumar,

Herein, we develop the first flexible, low-cost and high-performance hybrid electrode based on MnO2 and various levels of Ni doped MnO2 by employing a chemical precipitation method and characterized by various techniques. The X-ray diffraction patterns indexed to the tetragonal structure of α-MnO2. Morphological studies show the synthesized particles to be combined nanospherical with nanorod...

High Cholesterol Diet Induces Obesity in Zebrafish
Authors : C Justin David,R Rajapriya,V Veena,G Kumaresan,

Obesity is a non-communicable, multifactorial disorder characterized by relentless differentiation and accumulation of white adipose tissue (WAT) culminating in co-morbidities such as Type 2 Diabetes and cardiovascular disorders (CVDs). Consumption of cholesterol rich diet and lack of physical activity in coordination with Sterol Regulatory Element Binding Proteins (SREBPs), leptin and ghrelin...

Molecular Docking Studies of Biofilm Inhibitors Against Multidrug Resistant Pseudomonas Aeruginosa
Authors : A Sumithra ,P Vijayalakshmi,

The most prominent gram negative bacterium Pseudomonas aeruginosa that exist as a prevalent human pathogen emerged as a multidrug pathogen by expressing the formation of biofilm. These multiple drug resistant has become a major threat for current medical treatments. As the P.aeruginosa continues to develop resistance to the antibiotics due to its persistence in biofilm formation, the present...

Bauhinia purpurea L. Flower Mediated Dye used as Sensitizers for TiO2 Based Dye-Sensitized Solar Cells
Authors : Chinnappan Sudhakar,Thangaswamy Selvankumar,Kandasamy Selvam ,Munisamy Govindaraju,

An organic dye has become a viable alternative to expensive natural sensitizers because of their low cost of production, abundant in supply, and eco-friendliness. In this study investigates the relationship between the performance of a dye-sensitized solar cell (DSSC) sensitized by a natural sensitizer of Bauhinia purpurea L. flower dye extract. The dyes have shown absorption in a broad range of...
