Double endothermic and exothermic transitions during heating and cooling of thermoreversible polyacrylonitrile gels 来自 Semantic Scholar 喜欢 0 阅读量: 21 作者: Z Bashir 摘要: Squeeze-cast metal-matrix composite ingots have been manufactured by recasting A356/10% SiC(p) and by melt infiltrating A357...
The biological reac- tions responsible for cellular functions occur either exothermically or endothermically at particular locations within a cell, such as organelles. Hence, temperature distributions inside a living cell reflect the thermodynamics and functions of organelles6. Recently, the quantification ...
For SAT-5 film, endothermic and exothermic peaks corresponding to the α–β phase transition of Ag2Te were detected at 419 and 409 K during both heating and cooling processes, respectively [24,25]. This suggests that the small particles around large grains on free side were α-Ag2Te ...
This temperature control device is provided with: an endothermic/exothermic unit that heats or cools a subject to be subjected to temperature control; a temperature detection unit that detects the first temperature of the periphery of the subject; a control unit that controls the endothermic/...
Formation of solutions where the process is endothermic can be spontaneous provided that ___. A. they are accompanied by another process that is exothermic B. they are accompanied by an increase in order C. they are accompanied by an increase in disorder D. the solvent is a gas and ...

The STA analyses provided information on mass loss and exothermic/endothermic reactions as a function of sample temperature. The mass loss curves of the biomass ashes during STA heating could, in most cases, be explained from the chemical composition of the ash. Below 800 °C, weight loss is ...
