Thermal studies of cobalt, iron and tin metalloporphyrins

Gokakakar, S.D.; Salker, A.V. (Journal of Thermal Analysis and Calorimetry. 101(3); 2010; 809-813.)

A free-base tetraphenyl porphyrin (TPP) and its corresponding metalloporphyrins (MTPP) where M = Co, Fe and Sn were synthesized and characterized by UV-visible spectroscopy, FTIR and (1)Hnmr spectroscopy. Thermal studies ...
Synthesis of cobalt nickel ferrite nanoparticles via autocatalytic decomposition of the precursor

Gonsalves, L.R.; Mojumdar, S.C.; Verenkar, V.M.S. (Journal of Thermal Analysis and Calorimetry. 100(3); 2010; 789-792.)

The chemistry, structure, and properties of spinel ferrites are largely governed by the method of preparation. The metal carboxylato-hydrazinate precursors are known to yield nanosized oxides at a comparatively lower ...
Nuclear track detection using thermoset polycarbonates derived from pentaerythritol

Mandrekar, V.K.; Chourasiya, G.; Kalsi, P.C.; Tilve, S.G.; Nadkarni, V.S. (Nuclear Instruments and Methods In Physics Research Section B-Beam Interactions With Materials And Atoms. 268(5); 2010; 537-542.)

The paper describes the synthesis and performance of two polymers as nuclear track detectors, both having alpha sensitivity higher than that of the widely-used polymer CR-39. A homopolymer (PPETAC) from pentaerythritol ...
Syntheses of (-)-hygrine and (-)-norhygrine via Wacker oxidation

Majik, M.S.; Tilve, S.G. (Tetrahedron Letters. 51(21); 2010; 2900-2902.)

Hygrine is an important biosynthetic intermediate for tropane alkaloids. A synthesis of (-)-hygrine starting from L-proline is described. The acetonyl side chain of hygrine was fashioned through the Wittig reaction followed ...
Determination of track registration efficiency and radiation chemical yield for loss of ester bonds due to gamma rays in Cellulose Acetate Butyrate (CAB) nuclear track detector

Chavan, V.; Kalsi, P.C.; Nadkarni, V.S.; Pandey, A.K. (Journal of Radioanalytical and Nuclear Chemistry. 286(1); 2010; 181-183.)

The fission track registration efficiency of an indigenously prepared Cellulose Acetate Butyrate (CAB) solid state nuclear track detector (SSNTD) has been determined and is found to be (0.89 +/- 0.04).Radiation chemical ...
Low temperature carbon monoxide oxidation over nanosized silver doped manganese dioxide catalysts

Kunkalekar, R.K.; Salker, A.V. (Catalysis Communications. 12(3); 2010; 193-196.)

Nanosized silver doped manganese dioxide catalysts have been prepared and tested for CO oxidation reaction at lower temperature. Silver doped manganese dioxide catalysts show higher CO conversion as compared to undoped ...
Synthesis and anti-microbial studies of (E)-oxoalk-2-enoic acids

Kurangi, R.; Kadam, H.K.; Tilve, S.G.; Kerkar, S. (Journal of Chemical and Pharmaceutical Research. 2(4); 2010; 83-89.)

(E)-4-Oxonon-2-enoic acid 1a is a fatty acid, isolated from the mycelium of Streptomyces olevaceus. Owing to its significant activity against various Gram-positive and Gram-negative strains and particularly Staphylococcus ...
Synthesis, characterization, infrared studies, and thermal analysis of Mn0.6Zn0.4Fe2(C4H2O4)(3)center dot 6N(2)H(4) and its decomposition product Mn0.6Zn0.4Fe2O4

Gawas, U.B.; Mojumdar, S.C.; Verenkar, V.M.S. (Journal of Thermal Analysis and Calorimetry. 100(3); 2010; 867-871.)

Manganese zinc ferrous fumarato-hydrazinate precursor, Mn0.6Zn0.4Fe2(C4H2O4)(3).6N(2)H(4) was synthesized for the first time and characterized by chemical analysis, infrared spectral studies, and thermal analysis. Infrared ...
A simple method for synthesis of S-doped TiO2 of high photocatalytic activity

Bidaye, P.P.; Khushalani, D.; Fernandes, J.B. (Catalysis Letters. 134(41641); 2010; 169-174.)

S-doped TiO2 samples were synthesized by use of thiourea. The elemental analysis was confirmed by X-ray fluorescence, the phases were identified by X-ray diffraction and further characterization was carried out by surface ...
A calcium(II) coordination polymer based on a tricyclic dicalcium-bis(2-nitrobenzoate) building block

Srinivasan, B.R.; Shetgaonkar, S.Y.; Raghavaiah, P. (Polyhedron. 28(14); 2009; 2879-2886.)

The reaction of CaCO(3) with 2-nitrobenzoic acid (2-nbaH) results in the formation of a coordination polymer, [Ca(2-nba)(2)(H(2)O)(2)](n) (1) (2-nba = 2-nitrobenzoate), which can be dehydrated to [Ca(2-nba)(2)] (2). Compound ...
