    Naik, S.J.; Salker, A.V. (Catalysis Communications. 10(6); 2009; 884-888.)
    The compounds of Cu(1-x)Co(x)WO(4) series with different Cu-Co compositions were synthesized by co-precipitation method and sintered at 500 degrees C for the formation of monophasic compounds. These were characterized by ...
  • An introduction to thermodynamic modeling, thermal analysis and calorimetry 
    Mojumdar, S.C.; Prasad, R.; Sun, L.; Venart, J.E.S.; Eichhorn, S.H.; Iqbal, M.; Elkamel, A.; Madhurambal, G.; Meenakshisundaram, S.; Varshney, K.G.; Verenkar, V.M.S.; Jona, E.; Janotka, I.; Ray, A.; Chowdhury, B. (Research Journal of Chemistry and Environment. 13(4); 2009; 86-103.)
    Thermodynamic modelling is a powerful tool for predicting and understanding the behaviour of various systems. There are many thermoanalytical techniques such as thermogravimetric analysis (TGA), high resolution thermogravimetric ...
  • Tandem Wittig-Ene Reaction Approach to Kainic Acid 
    Majik, M.S.; Parameswaran, P.S.; Tilve, S.G. (Journal of Organic Chemistry. 74(9); 2009; 3591-3594.)
    The first example of a tandem Wittig-intramolecular ene reaction approach and its application toward the synthesis of kainic acid is reported. The synthetic pathway involves conversion of prenyl bromide into phosphorane ...
  • Total Synthesis of (-)- and (+)-Tedanalactam 
    Majik, M.S.; Parameswaran, P.S.; Tilve, S.G. (Journal of Organic Chemistry. 74(16); 2009; 6378-6381.)
    The first stereoselective route providing access to both enantiomers of tedanalactam, a naturally occurring piperidone, has been developed. The stereogenic centers were generated by the use of Sharpless asymmetric ...
  • New opportunities in acquisition and analysis of natural abundance complex solid-state S-33 MAS NMR spectra: (CH3NH3)(2)WS4 
    Jakobsen, H.J.; Bildsoe, H.; Skibsted, J.; Brorson, M.; Srinivasan, B.R.; Naether, C.; Bensch, W. (Physical Chemistry Chemical Physics. 11(32); 2009; 6981-6986.)
    Population transfer from the satellite transitions to the central transition in solid-state S-33 MAS NMR, employing WURST inversion pulses, has led to detection of the most complex S-33 MAS NMR spectrum observed so far. ...
