Phase-change memory based on Ti0.4Sb2Te3 material has one order of magnitude faster Set speed and as low as one-fifth of the Reset energy compared with the conventional Ge2Sb2Te5 based device. However, the phase-transition mechanism of the Ti0.4Sb2Te3 material remains inconclusive due to the lack of direct experimental evidence. Here we report a direct atom-by-atom chemical identification of ti...

Titania nanosheets are two-dimensional single crystallites of titanium oxide with a thickness of one titanium or two oxygen atoms, and they show attractive material properties, such as photocatalytic reactions. Since a titania (Ti₀.₈₇O₂) nanosheet is synthesized by the delamination of a parent layered K₀.₈Ti₁.₇₃Li₀.₂₇O₄ crystal using a soft chemical procedure, substantial Ti vacancies are expec...

Over the past many years, various bone plating systems have been developed to provide stable fixation for the mandible fractures were proposed and performed. The aim of the study was to evaluate efficacy of three dimensional (3-D)titanium mini plates in the management of mandibular fractures, and to analyze structural stability of the fractured bone fragments after fixation, to evaluate the bio...

A novel, miniaturized, high-efficiency photocatalytic cell, able to work in dynamic conditions, has been designed and validated in this study. Microfluidic channels were molded out of polydimethylsiloxane (PDMS) by means of standard soft lithography techniques, so as to work as photocatalytic cells, where the coupling of anatase titanium dioxide thin films and platinum electrodes, allows an ele...

A new anode/cathode design and process concept for thin wafer based silicon devices is proposed to achieve the goal of providing improved control for activating the injecting layer and forming a good ohmic contact. The concept is based on laser annealing in a melting regime of a p-type anode layer covered with a thin titanium layer with high melting temperature and high laser light absorption. ...

PURPOSE The purpose of this study was to evaluate the effectiveness of using titanium screws in combination with particulate human mineralized allograft, in a "tenting" fashion, to augment large vertical alveolar ridge defects for implant placement. MATERIALS AND METHODS This prospective case study evaluated augmentation in consecutive patients with large (>7 mm) vertical alveolar ridge defec...

OBJECTIVES A randomized controlled trial was performed to assess soft tissue cell adhesion to implant titanium abutments subjected to different cleaning procedures and test if plasma cleaning can enhance cell adhesion at an early healing time. STUDY DESIGN Eighteen patients with osseointegrated and submerged implants were included. Before re-opening, 18 abutments were divided in 3 groups corr...

This review aims to discuss the advantages and disadvantages of zirconia implants compared with titanium implants. Moreover, it intends relevant available long-term literature these two materials regarding osteointegration, soft-tissue, microbiota, peri-implantitis, focusing on clinical results. Briefly, are a reliable alternative for missing teeth; however, they not incapable failure. In an at...

OBJECTIVES The postoperative course following sternectomy for cancer carries significant morbidity due to paradoxical breathing, pulmonary infections and infectious complications. The purpose of this report is to evaluate the outcomes in patients undergoing sternal reconstruction using an innovative titanium rib bridge system (STRATOS). METHODS From 2008 to 2011, 24 patients underwent sternec...

BACKGROUND Magnesium alloys have recently been rediscovered as biodegradable implants in musculoskeletal surgery. This study is an ex-vivo trial to evaluate the imaging characteristics of magnesium implants in different imaging modalities as compared to conventional metallic implants. METHODS A CE-approved magnesium Herbert screw (MAGNEZIX®) and a titanium screw of the same dimensions (3.2x20...
