Biobased foams derived from lignins and tanins were produced by mechanical frothing and curing. The obtained foams did not crack after drying. The foams were found to be good thermal insulators with thermal conductivities ranging from 0.035 to 0.055 Wm-1K-1....
The reaction to fire properties of three commercial coatings designed for steel structures were investigated. The coatings in this study were covering a glass fiber-reinforced epoxy composite. It was determined that the thermal barrier effectiveness of these coatings was dependent on the degree of expansion and the thermal conductivity of the expanded char. Using these two parameters, the required thickness of a coating that can enable a structure to withstand ...
The use of sensors for the determination of content ratio in binary mixtures of fluids was investigated. The sensors were manufactured with various layouts of metal foil encapsulated by Kapton. Due to the difference in thermal conductivity between two fluids in a mixture, the thermal conductivity of the mixture is dependent on the ratio of the fluids. This method could be used in the future in Direct Methanol Fuel Cells (...
The thermal and physical properties of concrete were investigated at high temperature to determine how these properties might change in the event of a fire. The influence of the type and content of aggregate was also investigated. It was found that the degradation and mass loss of concretes depends on the type of aggregate used. It was also determined that the porosity of concretes increases as temperature increases, and that ...
The author presents a study done on methane hydrates to determine their thermal properties. Specifically, the thermal conductivity and thermal diffusivity are investigated to determine if these hydrates would be suitable as an energy source....
