This study focused on the crystallization kinetics behavior of pure ionic liquid (IL) (1-ethyl-3-methylimidazolium tetrafluoro borate; EMIMBF4) as well as IL confined in mesoporous silica matrices (termed as ionogel). X-ray photoelectron spectroscopy (XPS) and transient plane source (TPS) measurements have been used to explain the slowing down of crystallization process of IL in confinement. Thermal conductivity of the IGs was measured using pellets of #IG2 and #IG3 with the ...
In this paper, the physical characteristics of concretes containing three types of aggregates were examined under high temperatures. A thermal analyzer measured the thermal conductivity of the concrete samples using the transient plane source (TPS) method. Results showed that the thermal conductivity of well-crystallized concretes had a stronger inverse relationship with temperature than the poorly-crystallized samples did. As well, high-performance concretes retained their thermally conductive properties better than normal concretes....
In mold fluxes, fluorine is generally added to reduce viscosity and solidification. The fluorine however, tends to cause corrosion of the casting machine and leads to environmental pollution. To potentially rid this design of these issues, researchers in this study examined the Fluorine-free mold flux, in a specific glass system. Properties such as viscosity, thermal conductivity and crystallization behaviour were all analyzed and compared to the values for the commercial ...
