We performed Adiabatic Scanning Calorimetry (ASC) measurements on two ferroelectric liquid crystals: S-(-)-4-(2′ -methylbutyloxy)phenyl 4-n-octyloxybenzoate and S-(-)-2-methylbutyl 4-n-nonanoyloxybiphenyl-4′-carboxylate. Our experiments showed th

We investigated the smectic-A-hexatic-B (SmA-HexB) transition in the liquid-crystal n-hexyl-4’-n-pentyloxybiphenyl-4-carboxilate (65OBC) with adiabatic scanning calorimetry. We were able to prove in a direct way that this transition is indeed very

We investigated the specific heat capacity near the demixing transition of ternary mixtures of water, 3-methylpyridine and sodium bromide as a function of salt concentration. In this system, a crossover from Ising to tricritical behavior caused by th

Starch is one of the most important carbohydrate sources in human nutrition. For the thermal analysis of starch, techniques such as differential scanning calorimetry have been extensively used. As an alternative, we have applied a photopyroelectric (

We report high-precision measurements of phase transitions in the starch-water system by using for the first time adiabatic scanning calorimetry (ASC). Potato starch and nixtamalized corn flours were studied by this technique as a function of the moi

Differential scanning calorimetry (DSC) is a common method for the determination of certain thermophysical properties of matter, such as phase transition heat, specific heat, or phase and glass transition temperatures. In particular, the freeze conce

We have investigated the phase behaviour as a function of enantiomeric excess of a fluorosubstituted tolan derivative, FH/FH/HH18BTMHC, using high-resolution adiabatic scanning calorimetry (ASC). This substance exhibits a direct TGB to BP transition.

The glass transition of pure and diluted honey and the glass transition of the maximally freeze-concentrated solution of honey were investigated by differential scanning calorimetry (DSC). The glass transition temperature, of the pure honey samples a

High resolution adiabatic scanning calorimetry (ASC) was employed to study the phase behaviour exhibited by the chiral liquid crystal material (R)-1-methylheptyl 3-fluoro-4- (3-fluoro-4-octadecyloxybenzoyloxy)tolane-4-carboxylate (FH/FH/HH-18BTMHC).
