  • Srinivasan, B.R. (Journal of Thermal Analysis and Calorimetry. 119(2); 2015; 985-988.)
    Gopinath et al. report to have grown single crystals of thiourea urea magnesium chloride (1) (J Therm Anal Calorim 2012, 109:841-5) and urea thiourea sodium chloride (2) (J Therm Anal Calorim 2012, 110:789-92) from an ...
  • Srinivasan, B.R. (Published online on arXiv)
    It is argued that the ethylenediaminetetraacetic acid (EDTA) doped zinc sulphate heptahydrate crystal reported by Raja et al Spectrochim. Acta 99A (2012) 23 is the well-known zinc sulphate heptahydrate.
