Safety tests were conducted on cesium-loaded spherical resorcinol formaldehyde (SRF), resulting in a possible reclassification of the fire safety for the Cesium Ion Exchange Process System (CXP) emergency elution vessels, equipment, and piping. One of these tests was to determine the thermal conductivity using the transient line source technique, as thermal conductivity is a very important quantity for the safe treatment of materials....
In this study, researchers set out to test the performance of biocomposites reinforced with regenerated cellulose fibers and lactic acid thermoset bioresin. A difference in treatments was conducted as the cellulose fibers were surface treated with either silane or alkali. The main goal of this research was to improve the overall strength of the interactions at the fiber-matrix interface. Multiple strength tests, such as the tensile, flexural and impact strength ...
Intumescent epoxy resins are used commercially for fireproofing because of their ability to swell. The swelling action is initiated to shelter the materials beneath the resin from any potential heat source. In this study, the thermal degradation of the intumescent epoxy resins was researched, paying close attention to the morphology of the material and the overall swelling mechanism occurring. It was determined that the thermal degradation process inherently alters the ...
Resin polymers, such as Polymethyl methacrylate (PMMA), have been used in denture fabrication because of their easy molding ability and flawless appearance. However, these PMMAs are not the most desirable material when dealing with mechanical strength, electrical conductivity and thermal stability. In this study, the addition of fillers, such as Nano-Aluminum Oxide (Nano-Al2O3) and plasma treated polypropylene (PP) fibers, to these polymers has been explored. Nanocomposites are desired in ...
Multi walled carbon nanotubes (MWCNTs) and carbonized resorcinol-formaldehyde (RF) resin were used to create a conducting aerogel with a high electrical conductivity and Seebeck coefficient but a low thermal conductivity. The addition of the MWCNTs caused the figure of merit (ZT) for the aerogel to increase by two orders of magnitude. The researchers determined that it was possibly to control the electrical conductivity, thermal conductivity, and Seebeck coefficient independently of ...
