In this article, we have studied the size effect on glass transition and Kauzmann temperature of spherical TiO 2 nanoparticles using Arrhenius relation and Lindemann’s criteria under their dynamic limit. The melting point of nanoparticles decreases with decrease in size of the nanoparticles....
The square-pyramidal copper(II) complexes with ciprofloxacin in the presence of bipyridine derivatives have been synthesized and characterized using elemental analysis, magnetic moment measurement, thermal analysis (TG), IR, mass and reflectance spectra. The thermal denaturation study has been...
Two linear triblock copolymers poly( t -butyl methacrylate- b -2-hydroxyl ethyl methacrylate- b - N , N -dimethylaminoethyl methacrylate) (P t BMA 97 - b -PHEMA 18 - b -PDMAEMA 98 ) and poly( t -butyl methacrylate- b -glycidyl methacrylate- b -styrene) (P t BMA 137 - b -PGMA 23 - b -PSt 156 )...
Thermal behaviour of newly synthesized niobium(V) aryloxides of composition (NbCl 5− n (OC 6 H 4 CH(CH 3 ) 2 -4) n ) (where n = 1 → 5) synthesized by the reactions of niobium pentachloride with 4-isopropylphenol in predetermined molar ratios in carbon tetrachloride has been studied by...
The coordination complex of Cu (II) with the Schiff base derived from 4-chloroaniline with salicylaldehyde have been synthesized and characterized by micro analytical data; FT–IR, UV–Vis, FAB-mass and thermal analysis studies. Thermal data show degradation of complexes. We carried out thermal...
In this article, the role of the preparation route and calcinations temperature on the thermal expansion and conductivity of BaCe 0.8 Y 0.2 O 3−δ (BCY) has been studied. In particular, the samples were synthesized by means of the solid-state reaction and by a sol–gel route. BCY has been...
The influences of nanosized CaCO 3 on the thermal and optical properties embedded in poly(methyl methacrylate) (PMMA) and polystyrene (PS) were investigated. Calcium carbonate nanoparticles were synthesized by in situ deposition technique, and its nano size (32–35 nm) was confirmed by scanning...
Thermal characterization of materials provides conclusions regarding the identification of materials as well as their purity and composition, polymorphism, and structural changes. Analytical experimental techniques for thermal characterization comprise of a group of techniques, in which physical...
