OBJECTIVE To investigate the repair potential of CAD/CAM (computer-aided design/computer-aided manufacturing) ceramic and composite blocks using a silane-containing bonding agent with different repair protocols. MATERIALS AND METHODS Twenty-four discs were constructed from CAD/CAM ceramic and composite blocks. The discs were divided into six groups according to surface pre-treatment employed;...

In this study different sized sustained-release coated pellets (6, 2.5 and 1 mm in diameter) were investigated using terahertz pulsed imaging (TPI). Ten pellets from each batch of metoprolol succinate layered sugar starter cores coated with a 75:25 (w/w) polymer blend of Kollicoat SR and Kollicoat IR (approximate coating thickness of 60 μm, according to the weight gain) were mapped individually...

Titanium has broad application prospects in the field of hard bone tissue repair and replacement due to its low density, an elastic modulus similar that human bone, better biocompatibility than stainless steel cobalt-based alloys. However, titanium is a biologically inert material with biological activity. After implantation, it only physically bonds instead chemically bonding, which causes com...

Liquid permeation into silicone rubber (SR) may lead to the degradation or complete failure of composite insulators. Aiming inhibit liquid permeation, two kinds superhydrophobic coatings are applied SR surface. The properties with different types liquids investigated, and Langmuir diffusion model is analyse experimental data. results show that coating can effectively by reducing contact area be...

A series of Ca1–xSrxS:Eu (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) phosphors were synthesized by solid-state reactions. The Ca1–xSrxS:Eu phosphors have a strong absorption at 455 nm, which corresponds to the emission wavelength of a blue LED. The emission peak of Ca1–xSrxS:Eu is blue shifted from 655 to 618 nm with increasing Sr content. The characteristics of Ca1–xSrxS:Eu phosphors make them suitable...

Non-steroidal anti-inflammatory drugs (NSAIDs) have commonly been associated with upper gastrointestinal (GI) tract side effects including a high incidence of gastric and duodenal ulceration. Recent reports implicate NSAID use and mucosal injury in the small and large intestine. A trend in NSAID development has been an attempt to improve therapeutic efficacy and reduce the severity of upper GI ...

Surgical grade stainless steel (316L SS) is one of the widely used implant material in orthopedic surgeries. But often the release of metal ions is evidenced from the implants and subsequently a second surgery is required to remove the implant material. One way to control the release of metal ions is to coat the implant material with a biocompatible material like hydroxyapatite (HAp). Strontium...
