A numerical model is developed to describe the thermal conductivity, hydration, and moisture content of Portland cement mortar specimens. In order to develop the model, the thermal conductivity and specific heat of the mortar specimens were measured using the transient plane source method. The model ...
Low-density microcellular non-isocyanate polyurethane (NIPU) foams were prepared using biological compounds and carbon dioxide. The morphology of these foams was investigated by scanning electron microscopy (SEM), and the thermal conductivity was determined using the transient plane source (TPS) method. It was concluded that a study ...
Monolithic silica aerogels were synthesized with very low thermal conductivity (0.036 W/mK) and high porosity (97%) via ambient pressure drying. This method of drying replaces supercritical drying which is more costly and dangerous. The aerogel was derived from tetraethoxysilane (TEOS) and treatment with trimethylchlorosilane. NMR and ...
