Study of Carrier Transport in Organic and Inorganic Atomic Monolayer Based Nanoscale MOS Devices
Authors : J. Cyril Robinson Cyril Robinson,Rosilin George ,U. Satheesh ,P. Prakash ,D. Devaprakasam ,

Self Assembled Organic Monolayers such as organosilanes and Inorganic monolayers such as dichalcogenide semiconductor materials attracts wide research interest for potential nanoelectronics applications. We studied the scaling limit of Organic Monolayer such as Trichloro(1H,1H,2H,2H-perfluorooctyl)-silane (FOTS), Hexamethyldisilazane (HMDS) and Inorganic Monolayers such as hexagonal - Boron...

NMR Diffusion Studies on the Binding of Hyaluronate - Methotrexate Conjugates with Bovine Serum Albumin in Aqueous Solution
Authors : V. Aroulmoji aroulmoji,M. Bergamin ,R. Marega ,E. Murano ,

The study of the interactions of drugs with plasmatic proteins is of fundamental importance for the understanding of their biological applications and effects. The classical analytical techniques employed for the characterization of the degree of binding in such ligand/receptor systems are mainly based on separation method and spectroscopic characterizations. In the present study, we show that...

Irradiance Dependence on Performance of Dye Sensitized and V-Grooved Silicon Solar Cells
Authors : L. Arivuselvam L,D. Sakthi ,P. Sakthivel ,P. M. Anbarasan ,V. Aroulmoji ,

A relative normalized irradiance-dependent efficiency of photovoltaic modules is recommended as an objective means of quantifying their behaviour under variable irradiance conditions. It allows users to decouple the irradiance-dependent behaviour of photovoltaic modules from their temperature dependence. This criterion is shown to have a broad applicability in diagnostics by manufacturers and...

Efficient Medical Data and Medical Video Compression Using HEVC Standard
Authors : S. Kumarganesh M,M. Suganthi M,

The arrival of auto stereoscopic displays demands for the efficient compression of video which can acquire forward compatibility. CT or MRI Medical imaging produces digital form of human body pictures. There exists a need for compression of these images for storage and communication purposes. Current compression schemes provide a very high compression rate with a considerable loss of quality. In...

Spectroscopic Investigation, Optical, Electronic Excitation Mechanism and HOMO-LUMO Analysis of Glutamic Acid Crystal
Authors : N. Sakthivel L,A. Santhakumar ,P. M. Anbarasan ,

This paper presents the growth of optically non-linear organic crystal Glutamic acid using water by slow evaporation of aqueous solution at room temperature. The compound crystallizes in non-centrosymmetric space group P21/C. The FT-IR spectrum was recorded using a Perkin-Elmer FT-IR spectrometer. The optical characterization of the crystal shows the cut off wavelength near the UV region and also...

Microbial Production and Optimization of Biopolymer in Different Carbon and Nitrogen Sources
Authors : MPawenimana Innocent Innocent,Thangaswamy Selvankumar ,NDuwayo Fidele ,Arumugam Sengottaiyan ,

The biopolymer production with carbon and nitrogen sources plays a significant role as the biodegradable plastics. In the present study, eight bacterial strains were isolated from the milk waste amended in soil. The strains were identified on the basis of their morphological, cultural, physiological and biochemical characteristics. The identified strains are Bacillus species, Sporosarcina...

Green synthesis of silver nanoparticles using Cassia auriculata flower extract and its antibacterial activity
Authors : P. Srinivasan P,S.Sudhakar M,A. Sengottaiyan ,P. Subramani ,C. Sudhakar ,Koildhasan Manoharan ,P. Thiyagarajan ,

In the present study, silver nanoparticles were synthesized using flower extract of Cassia auriculata as a reducing agent by a simple and eco-friendly route. The aqueous silver ions when exposed to flower broth were reduced and resulted in green synthesis of silver nanoparticles. The reduced silver nanoparticle was characterized using different techniques such as UV-Visible spectrometer,...

Studies on Corrosion Behavior of Brass in Phosphoric Acid Medium with Chaetomorpha Antennia Extract
Authors : R. Selva Kumar R,V. Chandrasekaran ,

The effect of marine algae chaetomorpha antennia extract on corrosion inhibition of brass in phosphoric acid was investigated by weight-loss measurements. The inhibition efficiency is found to increase with increasing concentration of extract and the inhibition efficiency decreases with rise in temperature. The activation energy, thermodynamic parameters (free energy, enthalpy and entropy...

UV Protection Finishes on Textile Fabrics
Authors : Usha Sayed M,Rina Tiwari ,Prince Dabhi ,

Ultraviolet rays constitute a very low fraction in the solar spectrum but influence all living organisms and their metabolisms and these radiations can cause a range of effects from simple tanning to highly malignant skin cancers, if unprotected. This paper summarizes the interaction between ultraviolet radiation and textile surfaces and reviews the recent researches focused on the subject....

Bioremediation of Heavy Metals -An Environmental Cleanup Technology
Authors : M. Poonkothai Poonkoahai,

Release of toxic heavy metals as a result of industrial activities into the environment pose hazardous effects to aquatic and terrestrial organisms. Bioremediation, a biological processes degrade, break down, transform, and/or essentially remove contaminants or impairments of quality from soil and water. It is a natural process which relies on bacteria, fungi and algae to alter the...
