    Calorimetric Measurements at Low Temperatures in Toluene Glass and Crystal

    The specific heat of toluene in glass and crystal states has been measured both at low temperatures down to 1.8 K (using the thermal relaxation method) and in a wide temperature range up to the liquid state (u...

    Low-Temperature Specific Heat of Graphite and CeSb2: Validation of a Quasi-adiabatic Continuous Method

    We present the application of a fast quasi-adiabatic continuous method to the measurement of specific heat at 4He temperatures, which can be used for the study of a wide range of materials. The technique can be p...

    Crystalline phase transitions and acoustic phonons behaviour of polymorphic ethanol

    Ethanol shows a complex scenario of different crystalline phases in the temperature range between its glass transition at Tg = 97 K and its melting point at Tm = 159 K. Brillouin spectroscopy has revealed capab...

    Concentration and temperature dependence of the refractive index of ethanol-water mixtures: Influence of intermolecular interactions

    The temperature and concentration dependence of the refractive index, n D(x, T) , in ethanol-water mixtures agrees with previous data in the ethanol-rich concentration range. The refractiv...

    Looking for Ferromagnetic Signals in Proton-Irradiated Graphite

    Pure graphite, the stable crystalline allotrope of carbon at room temperature and ambient pressure, is known to exhibit a strong and anisotropic “textbook” diamagnetism, due to its delocalized π electrons. Nev...
