Titanium particles generated from orthopedic and dental implants are suspected to play an important role in peri-implant osteolysis. Elucidation of the mechanisms involved in the effects of titanium particles on osteolysis may provide methods for preventing osteolysis. Therefore, in the present study, we investigated the effect of titanium particles on osteoclast activity in vitro. We evaluated...

Titanium lattice structures have found a wide range of lightweight applications. However, made from the commonly-used commercially pure titanium (CP−Ti) and Ti−6Al−4V exhibit either low strength or post-yielding softening/collapse under uniaxial compression, making them less attractive to energy absorbing In present work, series gyroid been designed additively manufactured by laser powder bed f...

Based on our previous finding that a chromatography with titanium beads selectively binds phosphoproteins, including caseins, phosvitin and dentin phosphoproteins, we investigated whether bone phosphoproteins also bind to titanium. Bovine bone matrix proteins were extracted with 2 M urea/PBS after demineralization. The 2 M urea extract was directly applied to the titanium chromatography column ...

This work is aimed at studying the tribological contact between a titanium–aluminum–vanadium alloy pin (Ti6Al4V), produced by Electron Beam Melting (EBM), and sheet of ultra high molecular weight polyethylene (UHMWPE), which are widely utilized materials for prosthetic applications. Using “pin on disc” system, tribometric tests different duration (up to 240 min) were carried out in order trace ...

The aim of this study was to examine the influence of collagen coating on titanium on the initial attachment of human gingival fibroblasts for the development of the implant with periimplant soft tissue attachment. The morphological changes of cultured human gingival fibroblasts were investigated by scanning electron microcopy (SEM). Four different surfaces, i.e. non-coated mirror-polished tita...

PURPOSE The aim of this study was to evaluate whether photofunctionalization of titanium mesh enhances its osteoconductive capability. MATERIALS AND METHODS The titanium mesh (0.2 mm thickness) used in this study was made of commercially pure grade-2 titanium and had hexagonal apertures (2 mm width). Photofunctionalization was performed by treating titanium mesh with UV light for 12 minutes u...

This photocatalytic conversion of carbon dioxide laboratory experiment is designed for an advanced undergraduate chemistry or chemical engineering majors laboratory course. It introduces the science of emerging sustainable energy technologies through hands-on experimentation. By photo-irradiating a glass flask containing water, catalyst, and carbon dioxide, students explore the potential of new...

Abstract. Incremental sheet metal forming (ISMF) is a viable method for fabricating complicated three-dimensional structures from metal. It characterized by localized deformation and effective both rapid prototyping low-volume manufacturing. ISMF technology suitable quick product development time with affordable tooling deforming difficult-to-form materials. Simulation of the process reduces co...
