TL;DR: Interestingly, WTC(g) and delta C(p) showed a negative linear correlation, indicating that the change in heat capacity during the glass transition is associated with the strength of the hydrogen-bonding network in the glassy state.

Journal ArticleDOI
TL;DR: The crystallization and prevention of supercooling of the microcapsules are studied using differential scanning calorimetry (DSC) and wide-angle X-ray diffraction and there are multiple peaks on the DSC cooling curves that are attributed to liquid-rotator, rotator-crystal, and liquid- Crystal transitions.

TL;DR: It is proposed that the formation of a homogeneous solid solution is energetically favored if the particle size is reduced below a critical value, which amounts to about 1\char21{}2 nm, depending on the composition of the alloy and the temperature.
Abstract: Cu-Co has been chosen as a model system to study phase formation during mechanical alloying in systems with components exhibiting a positive heat of mixing. Phase formation is monitored by scanning electron microscopy, x-ray diffraction, and calorimetric measurements. Although the occurrence of a single fcc Bragg pattern cannot definitely prove the alloy formation on an atomic scale, the quantitative agreement of the heat release upon decomposition of the alloy with the heat of mixing, calculated from the available thermodynamic data of the system, is regarded as clear evidence for the formation of an fcc solid solution. As a mechanism of alloy formation the dissolution of Cu and Co particles during milling is discussed. It is proposed that the formation of a homogeneous solid solution is energetically favored if the particle size is reduced below a critical value, which amounts to about 1\char21{}2 nm, depending on the composition of the alloy and the temperature. The driving force is provided by the chemical contribution of the Cu/Co interface enthalpy and by the high configurational entropy of the randomly distributed atoms in the solid solution.

TL;DR: Differential scanning calorimetry (DSC) was used to study thermal transitions of the following whey proteins and enzymes in milk ultrafiltrate solution: β-Lactoglobulin, α-lactalbumin, serum albumin, γ-globulin this paper.
Abstract: Differential scanning calorimetry (DSC) was used to study thermal transitions of the following whey proteins and enzymes in milk ultrafiltrate solution: β-lactoglobulin, α-lactalbumin, serum albumin, γ-globulin, apo- and Fe-lactoferrin, lysozyme, ribonuclease, α-chymotrypsin and xanthine oxidase. Denaturation enthalpies (ΔHD), denaturation temperatures (TD) and the half width of the denaturation peaks in DSC thermograms (ΔT½D) were determined and the degree of renaturation was estimated by rescanning previously denatured samples. A fair correlation between the results obtained by DSC and other more classical methods was found in general. However, for some proteins (α-lactalbumin, lysozyme, ribonuclease and xanthine oxidase), which have so far been considered relatively thermostable, calorimetry reveals conformational changes starting at temperatures as low as about 45 °C. In these cases thermostability observed after heat treatment of milk should be interpreted in terms of renaturation and not of high temperatures of denaturation.
