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. ...
Researchers have determined the potential of increasing the thermal conductivity of insulating polymers by adding conductive fillers. One common application this may be used for, is fuel cell bipolar plates. In this article, researchers tested varying amounts of three different carbon fillers (black carbon, synthetic graphite particles, and carbon nanotubes), by adding them to polypropylene. Both single fillers and combination fillers were studied for their potential effects on the thermal ...
To maximize the energy efficiency of a building, and to minimize its carbon footprint, novel insulants have been extensively studied. Novel insulants such as phase change materials (PCMs) and hemp-lime insulation are proven to have extremely low thermal conductance. However, because these insulants are novel, they unfortunately have not been tested for fire safety. The purpose of this study was to create a fire framework to enable researchers to test ...
The measurement of thermal and ultrasonic properties of biological tissues is essential for the assessment of the temperature rise induced in vivo by diagnostic ultrasound. In this paper, we present measurements of thermal conductivity, thermal diffusivity, speed of sound and ultrasonic attenuation of fresh ex vivo porcine tissue, namely 'muscle' (from abdomen and leg), 'skin with subcutaneous fat' (from abdomen and leg), 'abdominal fat' and 'bone'. The measurements of the ...
Thermal Interface Materials (TIMs) are used in the field of electronics, to reduce the thermal contact resistance between the heat sink and heat source, to improve heat dissipation within the electronic device. In this experiment, researchers created a TIM by synthesizing Carbon Nano-Tubes (CNTs) on both sides of a thin copper foil. To test the thermal conductivity of the foil with this enhancement, the transient plane source method was employed. ...
