Molecules, Vol. 24, Pages 3777: Synthesis and Thermophysical Characterization of Fatty Amides for Thermal Energy Storage Molecules doi: 10.3390/molecules24203777 Authors: Anna Canela-Xandri Gemma Villorbina Mercè Balcells Xavier Fernández-Francos Luisa F. Cabeza Ramon Canela-Garayoa Nine monoamides were synthesized from carboxylic acids (C8–C18) and crude glycerol. The final monoamides were the result of a rearrangement of the acyl chain during the final hydrogenation process. The purity of the final compounds was determined by spectroscopic and mass spectrometry (MS) techniques. The thermophysical properties of solid monoamides were investigated to determine their capability to act as phase change materials (PCM) in thermal energy storage. Thermophysical properties were determined with a differential scanning calorimeter (DSC). The melting temperatures of the analyzed material ranged from 62.2 °C to 116.4 °C. The analyzed enthalpy of these monoamides ranged from 25.8 kJ/kg to 149.7 kJ/kg. Enthalpy values are analyzed considering the carbon chain and the formation of hydrogen bonds.

Conclusions: A group process with clearly progressing steps revealed that lonely older people are capable of empowerment and self-direction - despite their frailty and cognitive impairment. Facilitators should be familiar with group processes to enable them to progress effectively. PMID: 31714861 [PubMed - as supplied by publisher]

CONCLUSIONS: The device, which combined 20 g of CELOX particles and 20 pieces of CELOX (8 g) sponge tablets with 50-mmHg intra-abdominal compression for 10 minutes, prolonged the ST by an average of 30 minutes with less BL. It was not markedly different from the full four quadrants gauze packing of liver in hemostatic effect, with no CELOX clot formation in other organs.

This study shows simultaneous incorporation of two hydrophobic molecules and a hydrophilic molecule into distearoylphosphatidylcholine (DSPC) liposomes. Pinocembrin and cholesterol are incorporated in the lipidic membrane while resazurin is encapsulated in the aqueous center. The thermotropic behavior of liposomes as a function of the additives was studied with differential scanning calorimetry and the morphology was observed by SEM. A high percentage of entrapment was found for different concentrations of pinocembrin. Cholesterol does not interfere with the incorporation efficiency of pinocembrin and improves the distribu...
