Understanding in crystallization of polyethylene: the role of boron nitride (BN) particles

The authors examine the melting and crystallization behavior of a polyethylene/boron nitride composite to understand an unexpected exothermic peak when the BN content was greater than 10 wt. %. Based on these observations, an optimal annealing temperature of the composite was investigated to enhance its thermal conductivity. The appearance of the peak was determined to depend on the different nucleated capability of the different BN aggregates in local area. An annealing ...

Determination of thermal properties at Aspo HRL: Comparison and evaluation of methods and methodologies for borehole KA 2599 G01

This report is a comprehensive compilation of a variety of studies performed on rock in a borehole at a potential nuclear waste storage facility in Sweden. Density, water absorption, mineral composition and thermal properties were studied to determine the site's suitability as a safe storage area. Thermal properties are an important factor since the nuclear waste canisters will continue to give off heat in storage due to nuclear fission, and ...

Thermal transport of oil and polymer composites filled with carbon nanotubes

Carbon nanotubes (CNTs) have extremely high thermal conductivity and can raise the thermal conductivity of a polymer matrix when used as an additive. Previous research has shown that random CNT orientation in polymer matrices gives a much lower thermal conductivity value than a specific alignment direction. This project tested the thermal conductivity of oils and polymers. Results were encouraging, with the thermal conductivity of the composites increasing linearly with the ...

Thermal conductivity calculation of bio-aggregates based materials using finite and discrete element methods

In this study, the insulating properties of building materials made out of recycled plant particles were tested with both the laser flash method and the Transient Plane Source (TPS) method. The tests were conducted with aggregates of sunflower pith with particle sizes 1, 1.5, and 2.5 mm, to see how the thermal conductivity behaves with increasing air volume fraction between grains. The TPS method produced values with an increasing trend for thermal conductivity ...

Characterization of the carbonization process of expandable graphite/silicone formulations in a simulated fire

Preventing steel from losing its strength during fires is crucial for safe evacuation and effective fire fighting. One of the most common protective coatings applied to steel and other construction materials today is intumescent paint. In this study, researchers created a potential new protective coating using a curable silicone base and varying volume amounts of expandable graphite between 5-25%. The key characteristic of these coatings is that they swell to ...
