Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
The effective thermal conductivity and thermal diffusivity of polymer composites consisting of phenolformaldehyde matrix and oil palm empty fruit bunch (OPEFB) fibers were determined using the transient plane source method. The polymer composites were treated with one of alkali, silanol, or acetic acid to determine the effects of each treatment on the thermo-physical properties of the composites. The effect of temperature on these properties was also evaluated. It was determined ...
Molten selenium, silver, cadmium, and tin were used to prepare a-Se, and a-Se98M2 (M = Ag, Cd, and Sn) alloys in order to determine the thermo-physical properties of these materials using the transient plane source technique. In order for these alloys to be used in industrial applications such as phase change optical storage, photo electrochemical solar cells, and holographic recording systems, among others, their thermal transport properties needed to be ...
A series of chalcogenide glasses were prepared by substituting In into Se80Te20 to replace Te. The transient plane source (TPS) technique was then used to measure the thermal conductivity, thermal diffusivity and specific heat of the glass samples. It was determined that the substitution of Te with In caused the thermal conductivity of the sample to increase, although specific heat values remained nearly constant. Specific heat was also determined ...
Thermal conductivity and thermal diffusivity were simultaneously measured using the transient plane source (TPS) technique. These values were measured during heating from 303 to 323 K and cooling from 323 to 303 K. It was determined that both thermal conductivity and diffusivity were at their maximum at 313 K, which is in the range of the glass transition temperature....
Varying weight percentages of pineapple leaf fiber were added to phenolformaldehyde (PF) in order to generate a composite material. Using the transient plane source (TPS) technique, the thermal conductivities of the varying weight percentage composites were studied. It was found that increasing weight % pineapple leaf fiber resulted in decreasing thermal conductivity and diffusivity of the composites. The experimental results are compared to results produced by two models (the Rayleigh-Maxwell and ...
