Imidazole derivatives: Thermally stable organic luminescence materials

Physical and Structural Characterization of Biofield Treated Imidazole Derivatives

“…The stability of the complexes with both imidazole derivatives taken for this study depends mostly on the substituent situated between the nitrogen atoms of the imidazole ring [16]. Imidazole containing organic materials have better solubility in common polar organic and inorganic solvents compared to other heterocyclic moieties [17]. So in this study, Mr. Trivedi's biofield treatment was applied to treat imidazole derivatives for evaluation of their physical, thermal and spectral properties as compared to control.…”

Studies on optical, mechanical, dielectric properties of bisthiourea nickel bromide NLO single crystal

“…3 shows the variation of hardness with the applied load. It is observed that the hardness of bisthiourea nickel bromide increases by increasing the load up to 50 g, which indicates the reverse indentation size effect [14,15]. The increasing trend of microhardness with the load up to 30 g is well understood from the Mayer's law and Onitisch condition.…”
