Design of ceramic phosphor plate with functional materials for applications in high power LEDs 

Traditionally, white LED's are made by mixing phosphor with an epoxy resin. But, the phosphor is not always evenly distributed, and the epoxy resin has a low thermal conductivity resulting in accelerated thermal aging during operation. This article studies the effects of implementing a ceramic phosphor plate with varying concentrations of magnesium oxide, and silicon dioxide. It was found that as the magnesium oxide concentration increased so did the thermal ...

One-pot synthesis, characterization and properties of acid-catalyzed resorcinol/formaldehyde cross-linked silica aerogels and their conversion to hierarchical porous carbon monoliths

Aerogels are ultra-light, insulative, porous materials that have a wide variety of applications. The aim of this study was to synthesize resorcinol/formaldehyde (RF) cross-linked silica aerogels in one pot by acid catalysis. A thermal constant analyzer measured the thermal conductivity of the RF/SiO2 aerogels using the transient plane source (TPS) method. Results showed that although the RF/SiO2 aerogels had a lower density, their thermal conductivities resembled those ...

Properties of form-stable paraffin/silicon dioxide/expanded graphite phase change composites prepared by sol-gel method

In this article, researchers used the sol-gel method to create a thermally conductive phase change material (PCM), paraffin/silicon dioxide (SiO2)/expanded graphite (EG) composite. This PCM is composed of a supporting material, silica gel, and a thermally conductive material, expanded graphite. Thermal properties, such as conductivity and diffusivity were determined experimentally, and a differential scanning calorimeter was used to characterize the melting temperature and latent heat of the PCM. ...
