Development of antistatic finish in textiles
Authors : Usha Sayed,Kanchan Sharma,

Static electricity is a common problem in the world of polymers, which themselves act as electrical insulators. Static electricity causes the surfaces to pick-up dust or to stick to each other. A more dangerous consequence is its sudden discharge which, for example, can lead to a dust explosion. This paper suggests the remedies such as the addition of an antistatic agent to the base polymer. This... Read More

Molecular structure and spectroscopic properties of 4-methoxybenzaldehyde based on density functional theory calculations
Authors : S Govindarajan,P.B Nagabalasubramanian,

The molecular structure of 4-methoxybenzaldehyde (4MBA) was optimized by the DFT/B3LYP method with 6-311++G(d,p) basis set. The complete vibrational assignment and analysis of the fundamental modes of the compound are carried out using the experimental FTIR and FT-Raman spectra. The stability of the molecule arising from hyper-conjugative interaction and charge delocalization has been studied... Read More

Phytochemical Screening and GC-MS Analysis of Madhuca longifolia (L) Macbr.
Authors : R Thirumalaisamy,M Vaijayanthimala,S Govindaraju,A Subramanian,

The emergence of multi-drug resistant bacteria across the globe led the search for new and novel potential compounds from plant sources. In the present study phytochemical constituents from different extracts (Aqueous, methanol and petroleum ether) of Madhuca longifolia leaves were explored. The Preliminary qualitative analysis revealed the presence of alkaloids, flavonoids, steroids, tannins,... Read More

Anthracene based Organic Dye Sensitizer for Dye Sensitizer Solar Cell: Quantum chemical calculations
Authors : M Prakasam,A Arunkumar,A Priyadharsan,D Nicksonsebastin,P.M Anbarasan,

Based on quantum chemical calculations, we studied Anthracene ‐based dye for the Dye Sensitized Solar Cells (DSSCs) application. The D-π-A moieties of the designed organic dye molecule were optimized and absorption properties have been investigated by Density Functional Theory (DFT) and Time - Dependent DFT (TD-DFT) approaches. Further, the semiconductor TiO2 is used as a model to... Read More

Optimization of microwave-assisted extraction of natural dye from Ricinus communis L leaves
Authors : S Ramadevi,K Kalaiarasi,

The current study deals with the extraction of dye from Ricinus communis leaves using microwave assisted extraction technique and the colour yield was compared with conventional method. Factors affecting dye extraction such as extraction time, temperature, dye source concentration, pH and irradiation power was studied. The selected cotton fabric was dyed with the natural dye extracted by both... Read More

Structural and Vibrational Studies on 4-(4-Chlorophenyl)-4-Hydroxypiperidine using Experimental and DFT Methods
Authors : Ramachandran S,Prabakaran K,Velraj G,

In this present study, the molecular structure and spectroscopic properties of 4-(4-chlorophenyl)-4-hydroxypiperidine (44C4HP, C11H14ClNO) were characterized by FT-IR, FT-Raman and UV–vis spectroscopy. FT-IR and FT-Raman spectra in solid state were observed in the region 4000–400 cm1 and 4000–100 cm1, respectively. The spectroscopic properties were also investigated by the... Read More

The Art and Science of Teaching: Communicative English with Special Reference to Spoken Part
Authors : N Sampath Kumar,

English is a charismatic language that it attracts people across the universe, cutting the barriers of Nationality, Religion, Color, Creed, Caste and Community. There is undoubtedly a universal craze for the language among all non-native English... Read More

Optimization Machining Conditions on Composite Materials Using Fuzzy Logic
Authors : Dhavamani C,Rajan A.B.K,Sivakumar P,

Automotive, aircraft and train companies need to replace steel and cast iron in mechanical components with lighter high strength alloys like Al metal matrix composites (MMC).Experiments were carried out on Radial Drilling Machine. A plan of experiments, based on the techniques of Taguchi was performed. In this study drilling of Aluminium Silicon Carbide (Al/SiC) was investigated. The objective of... Read More
