[ 1 ] - Performing a Calcium-Phosphate Layer on Porous NiTi Alloy for Using in Orthopedic Applications
Porous NiTi alloys has a series of unique properties such as shape memory effect, superelastic behavior and energy absorbability that make them usable in a wide range of medical and industrial appliances. But the more probability of Ni release from a porous NiTi compare to the nonporous one has restricted it’s uses in implants. In the present research for resolving the problem, performing a cal...
[ 2 ] - Characterization of Constrained Aged Niti Strips for Using In Artificial Muscle Actuators (Technical Note)
Marvelous bending/straightening effects of two-way shape memory alloy (TWSMA) help their employment in design and manufacturing of new medical appliances. Constrained ageing with bending load scheme can induce two-way shape memory effect (TWSME). Scanning electron microscope (SEM) analysis, electrical resistivity measurement (ERM) and differential scanning calorimetry (DSC) are employed to dete...

[ 4 ] - Effect of Dual Releasing of β-glycerophosphate and Dexamethasone from Ti Nanostructured Surface for Using in Orthopedic Applications
Nano-structured surface and its ability to dual release of osteogenic and anti-inflammatory agents have a positive effect on the success of using titanium in orthopedic applications. For this purpose, TiO2 nanotubes (TNTs) were created via anodization method on Ti sheets and loaded by β-glycerophosphate (GP) and dexamethasone (DEX) as osteogenic and anti-inflammatory agents, respecti...
[ 5 ] - Synthesis and Characterization of Highly Porous TiO2 Scaffolds for Bone Defects
The purpose of this study was to fabricate and investigate the highly porous structure using titanium dioxide, which is a candidate for bone defect repairing. For this purpose, TiO2 scaffolds were synthesized using titanium butoxide, Pluronic F127 surfactant, and polyurethane foam blocks. Therefore, a colloid includes titanium butoxide and F127 and the polyurethane foams were immersed in it. Th...
[ 6 ] - Synthesis and evaluation of nanohydrogel film containing polyvinyl alcohol/hyaluronic acid/zinc oxide for wound dressing
Background and Aim: Lesions of the skin can impair its vital function to protect humans against external pathogens. Therefore, producing a suitable wound dressing to repair injuries is always one of the challenges of researchers. The present study aims to Synthesize a hydrogel film for wound dressing applications. Methods: In this research, a hydrogel film of polyvinyl alcohol / hyaluronic a...
