Eutectic mixtures of sugar alcohols for thermal energy storage in the 50–90°C temperature range

Badania termofizyczne materiałów zmiennofazowych w aspekcie ich zastosowań w układach do odzysku ciepła odpadowego

“…Przy wyborze odpowiedniego materiału należy brać pod uwagę stabilność właściwo-ści, toksyczności, bezpieczeństwo, palność oraz względy ekonomiczne [4]. Akumulacja ciepła z wykorzystaniem materiałów zmiennofazowych należy do metod stosowanych w systemach wysokotemperaturowych, które są użyteczne głównie w technologiach wykorzystujących odnawialne źródła energii (OZE), odzysku ciepła odpadowego oraz w energetyce [1][2][3][4][5].…”

Investigating therapeutic usage of combined Ticagrelor and Aspirin through solid-state and analytical studies

“…The mixtures were subsequently subjected to DSC measurements in a closed capsule by heating the samples at a rate of 10 K min -1 from 30 °C up to 160 °C. The DSC curves exhibited two endothermic peaks indicative of the occurrence of a eutectic and a liquidustransition (see Figure 1a) [16][17][18]. The onset temperature of the eutectic peak, 98°C, and the peak maximum of the liquidus peak were used to plot the temperature-composition TIC-ASA phase diagram ( Figure 1b).…”

Thermodynamic assessment of binary erythritol-xylitol phase diagram for phase change materials design

“…[11]- [18]) as well as blends ( [19]- [25]) being evaluated as PCMs. These include the binary polyols system erythritol-xylitol, proposed with a non-isomorphous simple eutectic phase diagram ( [19], [20]), or with a phase diagram containing a eutectic with solid-solid phase changes implying a partially isomorphous system ( [21], [25]). The non-isomorphous simple eutectic deduction was based on experimental assessments using: Differential Scanning Calorimetry (DSC) [19], [20]; Polarized Light thermo-Microscopy (PLM) [19]; X-ray Diffraction (XRD) [19]; Infra-Red thermography (IRT) [20], and theoretical modelling specific to non-isomorphous simple eutectic systems [19], [20].…”

The partially isomorphous system was deduced based on experimental evaluations with the Temperature-History (THistory) method [21], [25], complemented with Tammann Plots, XRD and Field-Emission Scanning Electron Microscopy (FESEM) [25].…”
