Abstract: Ag doped nano TiO2 was found to be an efficient photocatalyst in degrading acid alizarin violet N (AAVN) under visible light. The Ag doped nano TiO2 catalyst was synthesized by sol-gel method. XRD analysis as well as SEM micrographs showed these catalysts to be in nano size with a spherical morphology. The higher photocatalytic activity of Ag-TiO2 is explained due to the red shift in absorption as compared to nano TiO2 in turn owing to reduction in the band gap observed from UV-DRS analysis. AAVN dye was degraded to an extent of more than 98% on Ag doped TiO2 as compared to 90% by nano TiO2. The recycle studies on Ag-doped catalyst showing a stable degradation rates even after 5 runs indicate it to be a highly potential photo catalyst that may be employed in the successive degradation of AAVN dye in presence of visible light.

Abstract:This study was designed to study the viablility of producing biodiesels and their attendant blends from Annona muricata seed oil.The oils were obtained from the seed using sohxlet extractor in which case n-hexane was the solvent, the biodiesel was obtained by transeterification method using sodium methoxide and the petrol diesel obtained from the Nigerian national petroleum cooperation. Analysis were carried out according to the American standard for testing material ASTM Annona muricata seed showed considerable oil content. The biodiesel produced from this oil was regarded in this work as neat biodiesel and was labeled B100 and had comparable pour point, cloud point, flash point, fire point, viscosity and acid.....

Abstract: Two Schiff bases were prepared from nicotinic hydrazide and o-vanillin (H2L1) (1) or salicylaldehyde (H2L2) (3) and were characterized by elemental analysis, 1H and 13C NMR and IR spectroscopic studies. Compound were protonated in ethanol-nitric acid solution and gave compound [(H3L1).(NO3)] (2). The compound (2) crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 7.2005 (3) Å, b = 8.8914 (4) Å, c = 22.6392 (9) Å, = 96.753 (2)°, V = 1439.36 (11) Å3, Z = 4, R1 = 0.059 and wR2 = 0.037. The compound (3) crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 26.615 (4) Å, b = 11.3366 (14) Å, c = 8.1903 (9) Å, = 98.814 (3)°, V = 2442.0 (5) Å3, Z = 8, R1 = 0.085 and wR2 = 0.141. Both molecules present inter and intramolecular hydrogen bonds which consolidate the structures in three-dimensional networks.

Abstract:The N- hydroxyl methyl phthalimide (HMP) is one of the organic products which has tendency to react phenolic derivative. While there are number of ligands are employed for the formation of phthalimide derivatives. Hence the present work has been undertaking with following objectives. The transition metal complexes (i.e. Cu+2,Co+2,Ni+2,Zn+2, Mn+2) of ligand 5[(1,3 dioxo- 1,3 dihydro-2H-isoindol 2-yl)methyl]-2-hydroxy benzoic acid have been determined. All the metal complexes were monitored for their antimicrobial activity. The plant pathogens were employed for this purpose. The results give these conclusions. All the complexes are toxic more or less to fungi. The substitu-tion of phenyl rings does not have more effect on the fungicidal activity....

Abstract: The water resources evaluation through STD concentration (total solids dissolved) is one of the most specific ways to show natural interferences or even anthropic ones in the water resources of any ecosystem. Due to soils and urban areas occupation next to these water resources, it's necessary monitoring to determine if there is any anthropic action on them and verify the need of researching the most appropriate methods to its analysis. Therefore, this research aims to compare both Gravimetry and Conductometry analytical methods efficacy for STD determination. Gravimetry determines STD concentration from the drying sample and the obtained residue weight measurement afterwards. Conductometry obtains results by the presence of ions in solution using conductivimeter. The project analytical process was divided in two parts. First, tests were carried out with monovalent, bivalent and mixed......

Abstract: An Introduction to 'Green Plants' Green plants is a biological name that generalizes the colour in all plants. The colour is perhaps used to differentiate them from animal kingdom. But the term ' Green' does not imply that a plant is purely green . A close outlook shows that a single plant has got more than one colour apart from green plants. Definition : Green plants are impure living matter whose components of colours are more than one. Origin of colours and how they are used by plants......
