Silicone rubber (SR) is a common soft tissue filler material used in plastic surgery. However, it presents a poor surface for cellular adhesion and suffers from poor biocompatibility. In contrast, hydroxyapatite (HA), a prominent component of animal bone and teeth, can promote improved cell compatibility, but HA is an unsuitable filler material because of the brittleness in mechanism. In this s...

Article history: Received 28 October 2013 Received in revised form 5 December 2013 Accepted 26 December 2013 Available online 24 January 2014 In this work, we propose two carbon nanotube (CNT) network fabrication processes, the normal spin rate coating (NR) and the slow spin rate coating (SR), and two interconnect structures, the single layer structure (SL) and the double layer structure (DL), ...

Based on systematic first principles calculations, we investigate Sr surface segregation (SSS) in La(1-x)Sr(x)Co(1-y)Fe(y)O(3-δ) (LSCF) (a typical perovskite ABO(3) compound), a bottleneck causing efficiency degradation of solid oxide fuel cells. We identify two basic thermodynamic driving forces for SSS and suggest two possible ways to suppress SSS: applying compressive strain and reducing sur...

The present study was designed to investigate the effect of different types of coating polymers such as Eudragit RL 30D, Eudragit RS 30D, Eudragit NE 30D, Surelease, and Kollicoat SR 30D on physical properties and release pattern of salbutamol sulphate (SS) pellets which were prepared by Extrusion-Spheronization technology. All the polymers used in coating solution were in aqueous dispersion fo...

We explore theoretically the feasibility of functionalizing carbon nanostructures for hydrogen storage, focusing on the coating of C60 fullerenes with light alkaline-earth metals. Our first-principles density functional theory studies show that both Ca and Sr can bind strongly to the C60 surface, and highly prefer monolayer coating, thereby explaining existing experimental observations. The str...

The bioactivity of hydroxyapatite (HA) coatings can be modified by the addition of different ions, such as silicon (Si), lithium (Li), magnesium (Mg), zinc (Zn) or strontium (Sr) into the HA lattice. Of the ions listed here, strontium substituted hydroxyapatite (SrHA) coatings have received a lot of interest recently as Sr has been shown to promote osteoblast proliferation and differentiation, ...

Orally disintegratingtablets (ODTs) comprising sustained release (SR) coated microparticles smallerthan 250 µm provide an appealing dosage form for patients with dysphagia,offering a superior mouthfeel and highly convenient route of administrationwithout the need water. SR coating requisite size(<200 µm) is incredibly challenging however utilisation theMicroCoat™ techno...

Osteoporosis increases the risk of bone fracture by reducing mass and thereby increasing fragility. The addition strontium (Sr) nanoparticles in tissue results a strengthening bone, induction formation osteoblasts, reduction reabsorption osteoclasts. use Sr for regeneration has gained significant research interest recent years due to its beneficial properties treating osteoporotic-induced loss....

Hydrophobic grade fumed silicas are generally used in tabletting as lubricants. They are also found to retard the release of pharmaceutical actives. This is because of their hydrophobic nature, which gives good cohesive and adhesive properties. considering this point it was thought that they could be used as dry coating agents for solid dosages forms. The model drug selected for this work was p...
