Thermal conductivityBagasse ashMetakaolinThis research investigates the properties of geopolymer foams from metakaolin blended with bagasse ash activated by sodium hydroxide and sodium silicate and using hydrogen peroxide (H2O2) as a foaming agent at 0.5, 1.0, and 1.5 wt%. Geopolymer foams were cured ...
In this study, tetradecanol/graphene aerogel form-stable composite phase change materials were prepared by physical absorption. Two kinds of graphene aerogels were prepared using vitamin C and ethylenediamine to enhance the thermal conductivity of tetrad
The output of this device had been previously assumed to be linear, this assumption can lead to systematic errors of up to 5.6% in the determination of the para hydrogen concentration. A simple calibration procedure is described.关键词: Thermal conductivity Calibration ...
In addition, with the increasing accumulation of e-waste, the recyclability of TIMs has also become an urgent concern. Herein, a fully recyclable TIM with high thermal conductivity and conformability to the rough surface was prepared based on the synthesized epoxy vitrimer and boron nitride (BN) ...
Lubrication has become essential in enhancing engine efficiency in the era of rapid globalising. The tribological, oxidation and thermal conductivity properties of an engine oil play a vital role in improving the quality of a vehicle’s engine life. In t
