Silicone resin has recently attracted great attention as a high-power Light Emitting Diode (LED) encapsulant material due to its good thermal stability and optical properties. In general, the abrupt curing reaction of the silicone resin for the LED encapsulant during the curing process induces reduction in the mechanical and optical properties of the LED product due to the generation of residua...

Objectives: To compare the pulp chamber temperature during illumination of resin-based composites using different light-curing units, and to assess the effects of a glass-ionomer (GI) base on the increase of pulp chamber temperature during polymerization. Material and Method: Standard occlusal cavities were prepared and restored with the adhesive bonding agent Clearfil Liner Bond 2V and the com...

Curing of composite laminates in a vessel was investigated this study. The environment inside the processing dictates efficiency and ultimately drives quality thermoset parts. Experimental measurements spatial heat transfer coefficients were conducted on industrial scale vessels, including autoclaves large ovens, which final part using experimental data as input to coupled curing model. Measure...

Low pH and salt are two factors contributing to the inactivation of bacterial pathogens during a 60-day curing period for cheese. The kinetics of inactivation for Mycobacterium avium subsp. paratuberculosis strains ATCC 19698 and Dominic were measured at 20 degrees C under different pH and NaCl conditions commonly used in processing cheese. The corresponding D values (decimal reduction times; t...

This study aimed to investigate the impact of heat treatment on properties soy protein isolate film-forming solutions. The solutions, consisting isolate, glycerol, and phosphate buffer solution (pH 7.4), were subjected at 65, 75, 85°C for 2, 4, or 6 h. resulting films then analyzed tensile strength, elongation break, film solubility, color parameters, transparency. results indicated that increa...

background and aims. adding further fillers to dental resins may enhance their physical characteristics. the aim of this study was to evaluate the tensile strength of heat-curing acrylic resin reinforced by tio2 nanoparticles added into the resin matrix. materials and methods. commercially available tio2 nanoparticles were obtained and characterized using x-ray diffraction (xrd) and scanning ele...
