Visible Light Photoinitiator for 3D-Printing of Tough Methacrylate Resins
Lithography-based additive manufacturing was introduced in the 1980s, and is still the method of choice for printing accurate plastic parts with high surface quality. Recent progress in this field has made tough photopolymer resins and cheap LED light engines available. This study presents the influence of photoinitiator selection and post-processing on the thermomechanical properties of variou...
متن کاملDevelopment of functional resins by modification of ion - exchange resins and their application to analytical chemistry
Some novel functional resins were developed for highly selective separation and/or determination of mercury, selenium, fluoride and hydrogen peroxide, by simple modification of common ion—exchange resin with appropriate reagents. These reagents should have three functional properties, namely selective reaction with the determinant of interest, an ion—exchange reaction with the resin and physica...

در این پایان نامه روش جدیدی مبتنی بر روش حل معادلات دیفرانسیل پارهای بر اساس روش توابع پایه برای حل مسایل ارتعاش اجباری واستاتیک تیرها و صفحات لایه ای ارایه شده است که می توان تفاوت این روش با روش های متداول توابع پایه را در استفاده از توابع هموار در ارضاء معادلات حاکم و شرایط مرزی دانست. در روش ارایه شده در این پایاننامه از معادله تعادل به عنوان معادله حاکم بر رفتار سیستم استفاده شده است که مو...
15 صفحه اولThe effect of TiO2 and SiO2 nanoparticles on flexural strength of poly (methyl methacrylate) acrylic resins.
PURPOSE TiO(2) and SiO(2) nanoparticles are products of nanotechnology which have been incorporated to acrylic resins (AR) in order to induce antimicrobial properties. However, as additives they can affect the mechanical properties of the final product. The aim of this study was to survey the effects of TiO(2) and SiO(2) nanoparticles on flexural strength (Fs) of poly (methyl methacrylate) acry...
متن کاملEffect of Accelerated Artificial Aging on Translucency of Methacrylate and Silorane-Based Composite Resins
OBJECTIVES Composite restorations must have tooth-like optical properties namely color and translucency and maintain them for a long time. This study aimed to compare the effect of accelerated artificial aging (AAA) on the translucency of three methacrylate-based composites (Filtek Z250, Filtek Z250XT and Filtek Z350XT) and one silorane-based composite resin (Filtek P90). MATERIALS AND METHOD...
