Biocompatibility improvements for blood contacting materials are of increasing interest for implanted devices and interventional tools. The current study focuses on inorganic (titanium, titanium nitride, titanium oxide) as well as diamond-like carbon (DLC) coating materials on polymer surfaces (thermoplastic polyurethane), deposited by magnetron sputtering und pulsed laser deposition at room te...
Titanium nitride (TiN), a stable compound with the NaCl structure, has a wide range of properties which find applications in cutting tools, wear resistant parts, semiconductor metallization, and the jewelry industry. However, there are problems with preparing highly adhesive thin films which maintain good properties. Thin films of titanium nitride have been prepared by the Electron Shower (ES) ...
The suitability of titaniumnitride (TiN) for GaAs surface passivation and protection is investigated. A 2–6nm thick TiN passivation layer is deposited by atomic layer deposition (ALD) at 275 C on top of InGaAs/ GaAs near surface quantum well (NSQW) structures to study the surface passivation. X-ray reflectivity measurements are used to determine the physical properties of the passivation layer....
X-ray photoelectron spectroscopy (XPS) technique has been used to study carefully prepared oxide-free titanium nitride (TiN) films of nearly identicd stoichiometry, grown by direct sputtering and reactive evaporation. The lineshapes and pe~ positions of the Ti 2p and N 1s transitions are dependent upon the deposition method. The XPS results showed that oxynitrides me present following exposure ...
Abstract The formation of thrombi is still a challenge when it comes to ventricular assist devices (VADs). This can be caused by the subsequent deposition proteins and platelets on foreign surfaces. In VADs, blood contacting components are mainly made titanium alloys due hemocompatible properties corrosion resistance. However, surfaces where mechanical contact rotor stator occur like bearing ar...
The study focuses on the thermal and temperature sensitivity behavior of an optical fiber sensor device. In this article, a titanium nitride (TiN)-coated fiber Bragg grating (FBG) sensor fabricated using an ion beam sputtering system was investigated. The reflection spectra of the FBG sensor were tested using R-soft optical software to simulate the refractive index sensitivity. In these experim...
Microwave sintering (MWS) of commercially available 15-nm-size nanocrystalline TiN powder was studied. Densification kinetics and grain growth mechanisms of nano-TiN were evaluated using non-isothermal heating up to 1500 °C with variable heating rates. A true nanocrystalline ceramic with ~80-nm-size grains and 94.5 % theoretical density was obtained via MWS consolidation at 1400 °C. At higher t...
We examine the optical properties of nanostructures comprised of titanium nitride, TiN, an electrically conducting intermetallic-like compound. This material can be deposited in the form of durable films by physical vapor deposition. Use of nanosphere templating techniques extends the range of nanostructures that can be produced to include the versatile semi-shell motif. The dielectric properti...
This paper reports on the use of Zr-based (Zr53Cu33Al9Ta5) thin film metallic glass (TFMG) for the coating of syringe needles and compares the results with those obtained using titanium nitride and pure titanium coatings. TFMG coatings were shown to reduce insertion forces by ∼66% and retraction forces by ∼72%, when tested using polyurethane rubber block. The benefits of TFMG-coated needles wer...
