Increasing the thermal conductivity of an organic phase change material, all the while maintaining a high phase change enthalpy, is a difficult task. In this study, researchers took 1-tetradecanol/Ag nanowires composites, containing various wt% of Ag nanowires, and tested their thermal conductivities and phase change enthalpies. The results suggest the PCM composite containing 62.73 wt% of Ag nanowires is the most promising candidate for thermal conductivity enhancement of organic phase ...
Due to their high compressibility and resilience, nanofibrous aerogels (NFAs) have been proven to have positive insluative impacts on various applications with electronics and material damping. Up until this study, the fabrication of such nanofibers had proven to be very difficult. The scientists of this study homogenized nanofibre membranes, PAN/BA-a and SiO2 to create a nanofiber dispersion. This nanofiber dispersion was then freeze-dried to create uncrosslinked NFAs. The NFAs ...
This paper studied in-depth the transient hot plate method, by comparing this method to others in order to develop a short test time in which thermal effusivity and thermal conductivity can be measured simultaneously. To investigate this proposed model, four metal samples were analyzed using various techniques to ensure the accuracy between methods. To encompass a wide thermal conductive range, the thermal conductivities of the four metal samples tested, ranged ...
When referring to maximizing the energy efficiency of a building, one must first look at the contents of the structure: the make-up of the interior and exterior walls and the contents of the buildings envelope. Generally, when we think of insulation, we think of thermal insulation, which protects us from the blistering, hot days in summer to the dreaded cold days of winter. However, when constructing a building one must ...
Colloid chemistry has been of interest for many years. Researchers have begun to study the effects of metal particles on the stability and thermal properties of cooling liquids. The purpose of this study was to introduce metal particles to a solvent, resulting in a stable and thermally enhanced colloid. To serve as a reducing agent and a particle stabilizer, a cyclodextrin-glucose host-guest complex was synthesized to create aqueous metal colloids. ...
