Abstract :

Some zero valent organo palladium complexes and its oxidative addition products with 2- mercapto -3- phenyl quianazole-4-one (QPMTH) have been synthesized and characterized by various physico-chemical methods such as micro analytical, condcutance measurment, magnetic measurement, uv & visible and infrared spectrophotometric studies. The oxidation state of palladium metal after coordination is confirmed by iodometric titrations. The coordination of ligand to palladium metal is assigned through sulphur.

Abstract :

Various substituted 3 (7-substituted-6-fluoro-1,3-benzothiazole-2yl)-1-[(4-methylphenyl)sulfonyl]-2-thioxo-2,3-dihydroquinazolin-4 (1H)-one and 2-[(4Z)-4-benzylidine-2-phenyl-5-oxo-4,5-dihydro-1H-imidazole-1-yl]-N-(7 -substituted-6-fluoro-1,3-benzothiazole-2-yl) benzamide. Containing different functional groups have been synthesized by condensing Ethylchloroformate with substituted 2-aminobenzothiazoles in presence of anhydrous K2CO3. The identity of compounds were confirmed on the basis of their spectral (UV-Visible, IR, 1H NMR and Mass) data. Further, they have been screened for their antimicrobial, antiinflammatory, anticonvulsant and anthelmentic activities.

Abstract :

Throughout the geological history of the Earth, trace metals have played key roles in the evolution and maintenance of life. Its ability to react with organic and inorganic compound. It required by all organisms and is essential for number of metabolic reaction as concerned. Therefore, it was tried to throw an insight on certain trace metals viz. copper, zinc, manganese and iron. Concentration of these metals in plant extracts were found to be as Zinc (64ug/g), Iron (158 ug/g), Copper (49 ug/g), and Manganese (18 ug/g). These trace metals also have medicinal values.

Abstract :

A study on some complexes of Schiff base (MNSB) prepared from 2-hydroxynapthaldehyde and mesalamine (5-amino-salicylic acid) is presented here. The metal ions used for the complexation are Co (II), Ni (II), Cu (II), Mn (II), Zn (II) and Cd (II). The characterization of these complexes is attempted using various traditional tools like physical properties, elemental analysis, metal estimation and percentage yield. The modern techniques like magnetic measurements, infrared spectroscopy, UV and visible spectroscopy and thermo gravimetric analysis have also been applied to deduce the structure and bonding in these complexes. Using all the above data, an octahedral geometry for the complexes is proposed. While the tetra dentate Schiff base uses its four coordinating atoms (3 O's and 1 N) for bonding, the remaining two positions are occupied by aquo ligands.

Abstract :

4-amino-5-pyridin-4-yl-4H-1,2,4-triazole-3-thiol have been prepared by treating isonicotinic acid hydrazide (1NH) successively with alcoholic KOH, CS2 and hydrazinehydrate. These triazole derivatives were employed in the synthesis of 4-[substituted phenyl methylidene amino]-5-pyridin-4-yl-4H-1,2,4-triazole-3-thiol (1a-o) and N-[substituted phenyl]-3-pyridin-4-yl [1,2,4] triazolo [3,4-b] [1,3,4] thiadiazol-6-amine (2a-c). Some of they were found to be potential antimicrobial agents.

Abstract :

X-Ray Satellite spectra arising in 2p core level of heavy transition metal dihalides are calculated using plasmon theory. The energy separation and relative intensity attributes to the surface plasmon excitation and agreed well with the experimental data observed by D.C.Frost and M.Okusawa. The importance of surface plasmon oscillation is verified in satellites of heavy transition metal dihalides by comparison of experimental spectra.

Abstract :

Conventional Darlington pair is a popular circuit for amplification of small voltage signals and significantally used in many important applications. First time we have proposed a modification in CC/CE Darlington pair amplifier by replacing one BJT of the pair by FET with inclusion of a biasing resistance RP which produced some unseen results. We observed that the modified amplifier circuit produces high voltage gain with significant bandwidth. This circuit may be very useful for amplification of small signals with high gain in mid frequency bands and beneficial for various analog communication applications.

Abstract :

Electrical & magnetic properties of YBa2Cu3+xO7+d (x=0, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 1) superconducting materials, prepared by standard solid state reaction technique, is reported. X-ray diffraction pattern of the samples show that the structure of the samples were orthorhombic and single phase. The superconducting transition temperature Tc was determined from DC resistance and AC susceptibility measurement. DC resistance measurement for YBa2Cu3+xO7+d sample with x=0 showed a sharp superconducting transition having an onset temperature of about 91K. The AC resistance measurement also showed that the transition temperature Tc decreases as the copper concentration in the sample increases.The oxidation states of the samples increase with increasing copper content. It was observed that Tc decreases as copper content increases in the samples. The YBa2Cu4O7+d sample is a suppression of 2nd order phase transition (orthorhombic to tetragonal), which is a well known characteristic feature of YBa2Cu3O7+d superconductor. The stable oxygen content in YBa2Cu4O7+d makes the structure thermodynamically stable than the YBa2Cu3O7+d and as a result, no oxygen vacancies or twin structures are present in the YBa2Cu4O7+d sample.
