A p-dimethylaminobenzenesulfonate (MSE) polycrystalline powder is converted to the zwitterion p-trimethylammoniumbenzenesulfonate (ZWT) by chemical thermally induced reaction at T = 55,5°C. This reaction is associated to a first order ferroelastic p

We present a low-frequency Raman study of ${\mathrm{RbC}}_{60}$ in its orthorombic polymer phase. The ${H}_{g}(1)$ mode splits in three components at the polymer--orientationally-disordered-monomer phase transition ${(T}_{\mathrm{p}/\mathrm{d}}\mathr

The molar heat capacity temperature dependence of a fluorochloride glass whose composition is Cd0.50Ba0.13Na0.34K0.03Cl0.66F0.97 has a difference of 16 J/mol K between the solid and the liquid. Based on this difference, the liquid is fragile. The Deb

Some disubstituted diacetylene compounds (R-C ≡ C-C ≡ C-R', R=R' or R ≠ R'), the symmetrical pTS and DNP, present a quasi unique property : a large size monomer single crystal can be converted into single crystals of conjugated polymer. Structu
