This review thoroughly accumulated information regarding new technologies for state-of-the-art light curing of resin composite materials. Visible light cured resin-based composites allow the dentist to navigate the initiation of the polymerization step for each layer being applied. Curing technology was regularly subjected to changes during the last decades, but meanwhile the LED era is fully e...

Rigidization of inflatable space structures via internal resistive heating requires carbon fiber reinforced material to consolidate and cure on-command. In terms of the spacecraft’s life, the rigidization process transforms a structurally weak “balloon” into a robust, stable design. Internal resistive heating provides an active approach for inducing permanent shapeholding and structural stiffen...

OBJECTIVE Due to increasing of aesthetic demand, ceramic crowns are widely used in different situations. However, to obtain long-term prognosis of restorations, a good conversion of resin cement is necessary. To evaluate the degree of conversion (DC) of one light-cure and two dual-cure resin cements under a simulated clinical cementation of ceramic crowns. MATERIAL AND METHODS Prepared teeth ...

An accurate and stable record bases is needed for recording Maxillio-Mandibular relationship during the construction of a complete denture, toensure this accuracy the record bases should maintain close adaptation to the cast and to be dimensionallystable. Therefore, this study aimed to evaluate the changes of thickness and deformation of visible light cure acrylic denture base (VLCADB)after cur...

The mechanical properties and quality of the RTM resin products depends highly on the complete filling and curing of resins in the mold. Hence, a method for monitoring the filling and curing of resins in mold has been a challenging problem in the field of RTM fabrication for a long time, particularly for thick components. In this paper, we describe a promising online method to monitor the flow ...

Brittle epoxy based thermosets can be made tougher by introducing structural inhomogeneities at the micro- or nanoscale. In that respect, nano vesicles and worm-like micelles from self-assembling blockcopolymers have been shown to be very effective. This paper describes the curing kinetics and morphology of an epoxy composed of diglycidyl ether of bisphenol A (DGEBA) and 4,4'-methylenedianiline...

Due to growing environmental concerns of the cement industry, alternative cement technologies have become an area of increasing interest. It is now believed that new binders are indispensable for enhanced environmental and durability performance. Self-compacting Geopolymer concrete is an innovative method and improved way of concreting operation that does not require vibration for placing it an...

A design sensitivity method is used to find optimal autoclave temperature and pressure histories for curing of thermoset-matrix composite laminates. The method uses a finite element simulation of the heat transfer, curing reaction, and consolidation in the laminate. Analytical sensitivities, based on the direct differentiation method, are used within the finite element simulation to find the de...

Objectives were to test the effect of a lowsodium curing solution on processing characteristics of hams from purebred Berkshire pigs that were fed a step-up ractopamine HCl (RAC) feeding program or a negative control diet. Sixty pairs (n = 120) of hams were selected from two blocks of purebred Berkshire pigs (n = 200) that were fed either a control diet or 7.4 mg of ractopamine/ kg of diet for ...
