In this paper, we describe the study of the thermodynamic properties of all cycloketones, from cyclobutanone to cyclododecanone, through DSC measurements in order to reveal possible new glassy crystalline phases. This work presents revised phase diag

By slowly evaporating at room temperature solutions of C60 in n-octane, crystals of the hexagonal solvate C60 1 n-octane have been obtained (a = 10.10, c = 10.18 A)., Although these crystals are formed with a negative volume excess of − 24 A3 per f

Flutamide usually crystallizes in the orthorhombic non-centrosymmetric space group Pna21 (from I) and melts atT fus =384 K with Δfus H=30 kJ·mol−1. It may be obtained in the glassy state (T g =272 K) by quenching the melt. Although evidence of po

We have investigated structural transitions in Pr 2 NiO 4+δ(δ≥0) using DSC, TGA and XRD measurements. This study reveals firstly that the so called LTT (Low Temperature Tetragonal) phase i.e. P4 2 /ncm symmetry exists not only for δ=0 but also f

We have used neutron and X-ray diffraction techniques on both single crystal and polycrystalline samples to examine the symmetry of the unit cell of the organometallic compound uranium tris(cyclopentadienyl)chlorine, U(C5H5)3Cl, as a function of temp

Deuterated thiophene has been studied by powder neutron diffraction spectroscopy from ∼ 60 K to melting temperature. Preliminary DSC measurements have shown that the thermodynamic behaviours of hydrogenated and deuterated thiophene are almost ident

By means of a DSC study, 2-bromothiophene was shown to possess three different phases which melt at atmospheric pressure. These phases, the existence of which was subsequently checked by Raman spectroscopy, were obtained reproducibly through simple t
