The aim of this study was to evaluate the difference in the adsorption behavior of different types of bovine salivary proteins on the PMMA and Ti QCM sensors are fabricated by spin-coating and sputtering onto bare QCM sensors by using QCM and Xray photoelectron spectroscopy (XPS). SPM, XPS, and contact angle investigations were carried out to determine the chemical composition and surfacewettab...

This study investigates the surface modification of polyethylene terephthalate track-etched membranes by planar magnetron sputtering titanium and dioxide thin films to improve its hydrophilicity photocatalytic activity. After cold plasma treatment enhanced adhesion, Ti were deposited TiO2 reactive in an Ar-O2 gas atmosphere. The morphology was characterised using atomic force microscopy scannin...

The temperature stability of Ge/Au/Ni/Au ohmic contacts to GaAs nanoheterostructures and Ti/Al/Ni/Au GaN on silicon substrate was investigated. It has been established that optimization the RTA process made it possible obtain with field emission current flow mechanism. thermal for transistors mesa resistors demonstrated threshold behavior heat treatment temperature. optimum parameters minimum c...

The aim of this study was to develop a minimally invasive and reliable method for measuring peripheral chemoresponsiveness to oxygen in infants, and to establish baseline data from normal infants at 12 weeks of age. Two-breath alternations in fractional inspired oxygen (FI,O2), switching between 0.42 to 0.00 were given for 2 min periods via a face mask (held close to the face but without contac...

Two different kinds of two-dimensional (2D) materials, graphene oxide (GO) and titanium oxide nanosheets (Ti₀.₈₇O2(0.52-)), were self-assembled layer-by-layer using a polycation as a linker into a superlattice film. Successful construction of an alternate molecular assembly was confirmed by atomic force microscopy and UV-visible absorption spectroscopy as well as X-ray diffraction analysis. Exp...

MOTIVATION The transition/transversion (Ti/Tv) ratio and heterozygous/nonreference-homozygous (het/nonref-hom) ratio have been commonly computed in genetic studies as a quality control (QC) measurement. Additionally, these two ratios are helpful in our understanding of the patterns of DNA sequence evolution. RESULTS To thoroughly understand these two genomic measures, we performed a study usi...

In order to improve the corrosion and wear resistance of biomedical Ti-6Al-4V implants, a Ta₂N nanoceramic coating was synthesized on a Ti-6Al-4V substrate by the double glow discharge plasma process. The Ta₂N coating, composed of fine nanocrystals, with an average grain size of 12.8 nm, improved the surface hardness of Ti-6Al-4V and showed good contact damage tolerance and good adhesion streng...

Methods Using anodization method, TiO2 surfaces composed of vertically aligned nanotubes of 50-100 nm diameters were produced. The flat Ti surface was used as a reference. The alteration in the morphology of cancer cells was evaluated using scanning electron microscopy (SEM). A computational model, based on the theory of membrane elasticity, was constructed to shed light on the biophysical mech...

5 Abstract-Fretting fatigue is an important concern in the structures and machine parts that are subjected to repeated relative movements between them. In current study a review of the work done by various researchers related to the evaluation of fretting fatigue response of Ti-6Al-4V has been presented. Effects of surface treatments, crack growth, heat treatments, types of loading, contact pad...

Commercial purity titanium (CP-Ti) and a Ti-6Al-4V alloy (Ti64) were processed by high-pressure torsion (HPT) for 10 20 turns. The HPT processing produced nanostructured microstructure significant strength enhancement in the CP-Ti Ti64 samples. After turns, samples of HPT-processed subjected to laser surface treatments an air atmosphere using different scanning speeds powers. roughness laser-mo...
