This article evaluates the thermal conductivity of heat transfer nanofluids containing nickel coated single wall carbon nanotubes. The results concluded that with the introduction of a magnetic field, the thermal conductivity of the heat transfer nanofluid is improved. Researchers attribute this improved thermal conductivity to the ability of the nickel coated nanotubes to form aligned chains under the force of a magnetic field, allowing for better contact and ultimately a ...

Highly porous aerogels can be employed in a variety of applications; notably for this study, oil/water separation and sound absorption. Because of their poor mechanical functions, aerogels are limited within their array of applications. In this study, researchers set out to improve the mechanical performance of these aerogels. Researchers used thiol-ene chemistry and various alkoxy groups to prepare various novel bridged silsesquioxane (BSQ) precursors. Due to the contrasting hydrolyzing ...

Presently, converting waste into reusable materials is a high priority among researchers. This study presents the idea of recycling the natural rubber (NR) from latex condom waste, for its use as a potential filler in styrene butadine rubber (SBR). To properly understand the SBR material ratio aspect, thermal behaviour monitoring, such as thermal conductivity measurements using the Transient Plane Source method, was performed. A linear increase in thermal conductivity of ...

The researchers in this paper were the first to report that the thermal conductivity of the heat transfer nanofluids has the ability to be enhanced by an external magnetic field. This is possible due to carbon nanotubes and magnetic-field-sensitive nanoparticles of Fe2O3. It was discovered that the Fe2O3 nanoparticles form chains when exposed to magnetic fields, which allows the nanotubes to connect. As the nanotubes connect, the thermal ...

The Hansen solubility of two polyols, soy-castor oil based polyol and petroleum-based polyol, were measured to determine their use in polyurethane blends. The two polyols were determined to be miscible over a temperature range of 25 – 90˚C. Multiple ratio blends were tested to prepare the polyurethane foams. It was determined that with an increase in polyol content, the density of the open cell foams was increased. Also, as the bio-content increased, ...
