Glass transition in ultrathin polymer films: calorimetric study.
The ultrasensitive differential scanning calorimetry is used to observe the glass transition in thin (1-400 nm) spin-cast films of polystyrene, poly (2-vinyl pyridine) and poly (methyl methacrylate) on a platinum surface. A pronounced glass transition is observed even at a thickness as small as 1-3 nm. Using the high heating (20-200 K/ms) and cooling (1-2 K/ms in glass transition region) rates ...
متن کاملCalorimetric glass transition in a mean-field theory approach.
The study of the properties of glass-forming liquids is difficult for many reasons. Analytic solutions of mean-field models are usually available only for systems embedded in a space with an unphysically high number of spatial dimensions; on the experimental and numerical side, the study of the properties of metastable glassy states requires thermalizing the system in the supercooled liquid pha...

15 صفحه اولCalorimetric study of microsomal membrane.
Differential scanning calorimetric measurements of normal rat liver microsomes reveal a single thermal transition at about 50 degrees. This transition is assigned to irreversible prorein denaturation. There is no evidence for a reversible lipid phase transition at any temperature above 0 degrees, indicating that the microsomal membrane is in teh fluid state under these conditions. Rats fed a fa...
متن کاملCalorimetric Study of Nematic Prewetting
– We report specific-heat measurements for a series of liquid crystals imbedded in a porous cylindrical geometry. Above the nematic-to-isotropic transition and dependent on nematic width (or chain length), the specific heat shows a small peak. In analogy to known ellipsometry results, the peak is believed to be the signature of a nematic prewetting transition. The behavior of liquid crystals (L...
