Coating titanium alloy implants with titanium nitride (TiN) by the method of Powder Immersion Reaction Assisted Coating (PIRAC) produces a stable layer on their surface. We have examined the ability of the new TiN coating to undergo osseointegration. We implanted TiN-coated and uncoated Ti6Al4V alloy pins into the femora of six-month-old female Wistar rats. SEM after two months showed a bone co...

The industrial production of alkyl tin derivatives has increased rapidly in recent years, but little is known about the hazards to man which may exist in the handling of these substances. Interest in the matter has been sharpened by the catastrophic results of a therapeutic trial of one of the group, diethyl tin di-iodide, in the treatment of furunculosis. The compound was given orally and caus...

Three novel tin(iv)corrole complexes have been prepared and characterized by various spectroscopic techniques including single crystal X-ray structural analysis. Packing diagrams of the tin(iv)corroles revealed that corrolato-tin(iv)-chloride molecules are interconnected by intermolecular C-HCl hydrogen bonding interactions. HCl distances are 2.848 Å, 3.051 Å, and 2.915 Å, respectively, for the...

Spring-like superstructures consisting of layered tin(IV) hydrogen phosphate nanodisks can be obtained via a one-pot solvothermal reaction of tin tetrachloride and phosphoric acid in ethanol. These superstructures are active anode materials for the lithium-ion battery.

Unprecedented multi-channel TiN micro/nanotubes as well as various metal nitride nanofibers, including TiN, VN, NbN and ternary metal nitride nanofibers, were fabricated by a template free electrospinning method combined with post-nitridation.

A novel fullerene-porphyrin-fullerene triad linked by the axial coordination of tin(IV) porphyrin is reported, exhibiting strong pi-pi interactions between the tin porphyrin and fullerene moieties owing to their close proximity.

Cathodoluminescence (CL) spectra have been recorded from float glass samples and the data used to determine the depth profile of tin introduced from the float process. The luminescence data were interpreted in terms of intrinsic emission bands at 380 and 410 nm and well resolved extrinsic emission bands resulting from the tin impurities at 575 and 630 nm. Signals were recorded at temperatures f...

We study N-K-edge electron energy-loss near-edge structures for well-defined TiN/VN bilayers grown on a MgO(100) substrate by both calculations and experiments. The structural relaxations and the electronic structure of TiN/VN multilayers are calculated using the Vienna Ab Initio Simulation Package computer code, which uses density functional theory to describe the electronic interaction. The e...

In heavy loaded mating components, such as sliders and sliding bearings, guaranteeing the efficiency of lubricant films for long times during severe service conditions is very complicated. In this work, the benefits deriving from the use of fiber laser sources for surface texturing of very thin TiN coatings in severe wear working conditions were demonstrated. Evaluations of the laser textured d...
