This paper reports the results of studying effect two additives such as polyether siloxane (PS) and sodium polyacrylate (SPA) on wetting various substrates in water-borne paints (WB paints). Titanium dioxide (TiO2), paraffin (PA), steel (ST), glass (GL) were used solid substrates. The edge angle (?0) ratio (dCos?/d?S) criterion for assessing wettability In aqueous solutions (without acrylic res...

Titanium alloys have been widely used in many industrial applications. Nevertheless, efforts to improve their properties are continually increasing. One of the most effective routes strength, hardness and wear resistance is create a coating layer on substrates. In current study, stainless steel was selected for in-situ joining creating continuous Ti6Al4V alloy. The process carried out at two di...

We study the Casimir force between a nanoparticle and a substrate. We consider the interaction of metal nanoparticles with different substrates within the dipolar approximation. We study the force as a function of the distance for gold and potassium spheres, which are over a substrate of titanium dioxide, sapphire and a perfect conductor. We show that Casimir force is important in systems at th...

In order to increase the bone bioactivity of metallic implants, hydroxyapatite (HA: Ca10(PO4)2(OH)6) is often coated on their surface so that real bond with surrounding bone tissue can be formed. In present study, HA coatings were deposited on AISI 316L SS and titanium using shrouded plasma spray process. The coated specimens were subjected to X-ray diffraction (XRD) analysis, field emission sc...

The novel method of the semiconductor nanostructuring (TINE&MEMO) has been developed on the base of the simultaneous AFM-tip induced local anodic oxidation and mechanical modification of the surface under the applying of advanced electric potentials. The TINE&MEMO-based technology allows obtaining the principle new scale of the depth up to 100 nm for the nanostructure fabrication with a low asp...

We study the atomic layer deposition of TiO2 by means of X-ray absorption spectroscopy. The Ti precursor, titanium isopropoxide, was used in combination with H2O on Si/SiO2 substrates that were heated at 200 °C. The low growth rate (0.15 Å/cycle) and the in situ characterization permitted to follow changes in the electronic structure of TiO2 in the sub-nanometer range, which are influenced by q...

In the present study, selenium (Se) nanoclusters were grown through heterogeneous nucleation on titanium (Ti) surfaces, a common orthopedic implant material. Normal healthy osteoblasts (bone-forming cells) and cancerous osteoblasts (osteosarcoma) were cultured on the Se-doped surfaces having three different coating densities. For the first time, it is shown that substrates with Se nanoclusters ...

The microstructures and the phase transformation temperatures of sputtered titanium–nickel (TiNi) thin films, both free-standing and attached on different underlying multi-layer substrates, have been studied. Differences in the microstructures, such as the lattice constants and relative concentrations of TiNi, Ti2Ni and TiNi3 phases, have been observed among the free-standing and the attached f...
