| Authors | : | Dr.B.Senthil kumar |
Abstract:TiO2 Nano Particles have been synthesized using titanium tetrachloride as precursor through Sol-gel technique. The characterization of synthesized particles was done in XRD and FTIR analysis. It is revealed from XRD and FTIT spectroscopy that the TiO2 nano particle formation. Subsequently the synthesized particles were applied on the Cotton textile plan woven fabrics using pad patch method using 1 wt% of acrylic binder. While coating three different contraction of TiO2 Nano particles were maintained. The self cleaning action of nano coated fabric has been quantified by measuring photo catalytic degradation of stain due to visible light irradiation. %of Decrease in K/S value is increased with respect to increase in TiO2 concentration as well as duration of visible light irradiation.

Abstract:In vivo anthelmintic activity of a herbal drug processed through spray-drying from Prosopis juliflora (Sw.) DC) and Entada leptostachya (Harms) against gastrointestinal nematodes of sheep is described and reported for the first time in this work. Maximum percent egg count reduction (%ECR) of 80.95% in egg per gram of faeces (EPG) on day 11 post-treatment (PT) was recorded in sheep treated with a dose of 250 mg/kg b.w. of the herbal drug mixture. This was followed by a reduction (P≤0.05) of the same dose treatment (59.80%) on day 8 PT. The positive control exhibited the highest egg count reduction (P˂0.01) with an EPG of 88.31% on day 14 PT (P≤0.05).

| Title | : | Studies of transition metal ion - 5- Sulphosalicylic acid doped Polyanilines |
| Country | : | India |
| Authors | : | N. Muneeswaran |
Abstract: Metal ion-5-sulphosalicylic acid (5-SSA) complexes were used as dopant for Emeraldine base to prepare high spin polyaniline metal composites.The so prepared emeraldine salts were characterized by FT-IR, magnetic susceptibility, conductivity, X-ray diffraction(XRD) and Surface electron microscopy (SEM) studies in order to understand the influence of functionalized dopants on the physico-chemical properties of polyaniline. The conductivity was increased on increasing the concentration of metal ion complexes. Magnetic measurements showed a negative magnetic susceptibility (χg) value for 5-sulphosalicylic acid doped polyaniline while positive magnetic susceptibility (χg) values were found for the transition metal ion doped polyanilines. XRD study showed that the polymers are in amorphous state and it contained metal ions. Surface electron microscope analysis showed that the morphological structure of the doped polyaniline had small grain particles with particle sizes varied from 10 – 500μms.
