A ferrogel for magnetically controlled release of drugs is prepared by integration superparamagnetic iron oxide nanoparticles and Pluronic F127 gels. The hydrophobic drug indomethacin loaded in the owing to oil-in-water micellar structure. characteristic sol–gel transition property renders an injectable carrier that will be, principle, free from surgical implant procedure.
Ti–W–V–N composite films with different vanadium contents were synthesised by multi-target reactive magnetron sputtering. The microstructure, mechanical and tribological properties of investigated X-ray diffraction, scanning electron microscope, high-resolution transmission microscopy, nanoindentation high-temperature ball-on-disc tribometer. results showed that all the face-centred cubic (fcc) structure, consisting fcc-(Ti,W,V)N substitutional solid solution. When V content ≥21.5 at.-%,...
In this study, reactive magnetron sputtering was applied for preparing NbCN-Ag films with different Ag additions. contents in the as-deposited were achieved by adjusting target power. The composition, microstructure, mechanical properties, and tribological properties characterized using energy-dispersive X-ray spectroscopy (EDS), diffraction (XRD), field emission scanning electron microscope (FE-SEM), high resolution transmission microscopy (HRTEM), Raman spectrometry, nano-indentation,...
Titanium boron nitride (Ti-B-N) films with various contents were deposited using titanium and targets in a reactive magnetron sputtering system. The content the film was varied from 0 at.-% to 8.7 at.-%, evaluate its properties. Various analytical techniques such as X-ray diffraction, high-resolution electron microscopy, nanoindentation ball-on-disk dry sliding etc. used. Incorporation of B into influenced microstructure, mechanical room-temperature tribological At 0.2 exhibited highest...
Ti–B–N (nc-TiN/ a-BN) composite coatings with various boron contents were deposited by magnetron sputtering. nano-indentation, ball-on-disc dry sliding X-ray diffraction, and, Raman spectroscopy was used in evaluating the compositional, mechanical and tribological properties of these coatings. The corrosion behaviour assessed electrochemical potentiodynamic polarisation method a 3 mol-% NaCl solution. coefficient friction (CoF) initially increased to 1.0 when test temperature 200°C, but...
The barrier properties and diffusion behavior of Cu(Re) alloy films were studied. deposited onto barrierless SiO2/Si by magnetron sputtering. X-ray diffraction patterns electric resistivity results proved that the without a layer thermally stable up to 550 °C. Transmission electron microscopy images energy-dispersive spectrometry employing scanning transmission provided evidence for self-formed Re-enriched between substrate. Furthermore, chemical states Re atoms at Cu(Re)/SiO2 interface...
