Induction heating treatment (IHT) has recently been used to improve the bioactivity and biocompatibility of titanium its alloys, greatly related formation nanoscale oxide coating. In this work, effect ultrasonic on IHT oxidation behavior pure investigated. Ultrasonic-assisted was carried out for 13, 20 25 s. Submicro-/nano-scale morphological coatings with rutile anatase TiO2 were prepared surf...

Abstract The bonding mechanisms of a wide range metallic materials in cold spraying have been studied, mainly attributed to adiabatic shear instability (ASI) at high strain rates, whereas the impact and deformation behavior entropy alloys (HEAs) onto various substrates has not widely explored. HEAs characterized by excellent strain-hardening ability resistance localization, which can influence ...

In this work, the potential of ZnO nanowire arrays decorated with titanium nitride (TiN) nanoparticles as surface-enhanced Raman scattering (SERS) substrates is demonstrated. nanowires were grown by hydrothermal synthesis while commercially obtained TiN powders subjected to several hours mechanical grinding achieve 30–100 nm diameter nanoparticles. The then dispersed in acetone and drop cast on...

Previous studies have demonstrated greater functions ofosteoblasts (bone-forming cells) on nanophase compared with conventional metals. Nanophase metals possess a biologically inspired nanostructured surface that mimics the dimensions of constituent components in bone, including collagen and hydroxyapatite. Not only do these components possess dimensions on the nanoscale, they are aligned in a ...

A possibility of laser printing single diamond nanoparticles with luminescent SiV centers is demonstrated. To provide the transfer, a target consisting transparent sapphire plate and an absorbing thin titanium film (600 nm thick) coated was irradiated KrF excimer ("lambda"=248 nm, "tau"=20 ns). Optimal values fluence have been determined technique for applying labels targeted transfer has devel...

Titanium nitride is an attractive material for a range of superconducting quantum-circuit applications owing to its low microwave losses, high surface inductance, and chemical stability. The physical properties device performance, nevertheless, depend strongly on the quality materials. Here we focus highly crystalline epitaxial titanium thin films deposited sapphire substrates using magnetron s...

Electrically conductive materials provide a suitable platform for the in vitro study of excitable cells, such as skeletal muscle cells, due to their inherent conductivity and electroactivity. Here it is demonstrated that bioinspired electroconductive nanopatterned substrates enhance myogenic differentiation and maturation. The topographical cues from the highly aligned collagen bundles that for...
