The development of a microfabricated transient planar source (TPS) sensor for measuring thermal conductivity of nanofluids

The addition of thermally conductive nanoparticles to conventional heat transfer fluids enhances their performance so they can be used for high-powered applications. However, as nanoparticles are added, the liquid becomes more viscous, which decreases thermal conductivity. Changing the pH of the solution can control the ...

Systematic studies of tannin–formaldehyde aerogels: preparation and properties

A variety of tannin-formaldehyde aerogels were produced in order to examine the effects of pH and dilution during their manufacture. The authors produced a phase diagram that could describe them. Extensive physical property characterization was performed on the sample aerogels, including porosity, thermal conductivity, volume ...

Effect of pH and chemical surfactant on thermal conductivity enhancement of Cu-H2O nanofluids 

This study investigates the effect changing the PH of a copper nanofluid and sodium dodecylbenzenesulfonate (SDBS) surfactant concentration has on the thermal conductivity of the nanofluid. The thermal conductivity was determined through the Hot Disk Transient Plane (TPS) method. As the PH is increased the ...

Reduction of shrinkage and brittleness for resorcinol-formaldehyde aerogels by means of a pH-controlled sol-gel process 

This article investigates how the thermal conductivity of a resorcinol-formaldehyde aerogels varies with increasing resorcinol (R) to water (W) ratios. The thermal conductivity was measured using a transient plane source (TPS) method. As the R:W increases so does the thermal conductivity, this is because ...

New tannin-lignin aerogels

Tannin and lignin are organic materials that are more cost-effective than synthetic, non-renewable phenolic compounds. In this paper, tannin-lignin-formaldehyde (TLF) composites were used to synthesize thermally insulative mesoporous aerogels. A thermal analyzer measured the thermal conductivity of two TLF samples using the transient plane source (...
