Dental ceramic implants have shown superior esthetic behavior and the absence of induced allergic disorders when compared to titanium implants. Zirconia may become a potential candidate to be used as an alternative to titanium dental implants if surface modifications are introduced. In this work, bioactive micropatterned silica coatings were produced on zirconia substrates, using a combined met...

A soft x-ray microbeam using proton-induced x-ray emission (PIXE) of characteristic titanium (K(α) 4.5 keV) as the x-ray source has been developed at the Radiological Research Accelerator Facility (RARAF) at Columbia University. The proton beam is focused to a 120 μm × 50 μm spot on the titanium target using an electrostatic quadrupole quadruplet previously used for the charged particle microbe...

Using noiseless solid-state CR-39 plastic track and Al2O3:C thermo-luminescent detectors, the yields of 3.0 MeV protons from DD-reaction and soft x-ray photons emitted from the cathode were studied in the periodic pulsing deuterium glow discharge with titanium cathodes at low discharge voltages (in the range 0.8–2.5 kV) and high current density (300–600 mA/cm2). The analysis of DD-proton yield ...

BACKGROUND The radial head is considered the main stabilizer of the elbow when the medial collateral ligament and lateral ulnar collateral ligament have been compromised. Radial head replacement (RHR) is indicated for patients with irreparable or non-united radial head fractures associated with elbow stiffness or instability. The present study aimed to analyze the clinical results after treatme...

OBJECTIVE The aim of this study was to compare crestal bone-level changes, soft tissue parameters and implant success and survival between small-diameter implants made of titanium/zirconium (TiZr) alloy or of Grade IV titanium (Ti) in edentulous mandibles restored with removable overdentures. MATERIALS AND METHODS This was a randomized, controlled, double-blind, split-mouth multicenter clinic...

AIMS AND OBJECTIVES The aim is to study the effectiveness of 2 mm three-dimensional (3D) titanium miniplates and 2 mm conventional titanium miniplates in osteosynthesis of mandibular fractures by comparing the change in bite force. METHODOLOGY The study comprised forty patients of age group 20-40 years, weighing 55-75 kg having mandibular fractures. Patients were randomly divided into two equ...

The binary alloy of titanium-tungsten (TiW) is an established diffusion barrier in high-power semiconductor devices, owing to its ability suppress the copper from metallisation scheme into surrounding silicon substructure. However, little known about response TiW high temperature events or behaviour when exposed air. Here, a combined soft and hard X-ray photoelectron spectroscopy (XPS) characte...

the concept of soft sets, introduced by molodtsov [20] is a mathematicaltool for dealing with uncertainties, that is free from the difficultiesthat have troubled the traditional theoretical approaches. in this paper, weapply the notion of the soft sets of molodtsov to the theory of hilbert algebras.the notion of soft hilbert (abysmal and deductive) algebras, soft subalgebras,soft abysms and sof...
