This paper describes a strategy for designing a chemically anchored phospholipid monolayer that could be used as coating materials for biomedical implants. To make a chemically anchored phospholipid monolayer on the polymer substrate, we prepared the mono-acrylated phospholipid (1-palmitoyl-2-[12-(acryloyloxy)-dodecanoyl]-sn-glycero-3-phosphocholine; acryloyl-PC) and the acrylated polymer (poly...

Si-Co diffusion coatings were prepared on a Y-modified TiAl-Nb alloy using the pack cementation process. The structures of at different temperatures (1050, 1080, and 1120 °C) Co contents (5, 10, 20 wt.%) comparatively studied. possessed typical structure (Ti,X)Si2+Ti5Si4 (X represents Nb Al elements) outer layer with Co-rich superficial zone, Ti5Si4+Ti5Si3 middle layer, TiAl2 inner layer. Incre...

The mixture of poly(lactide-co-glycolide) (PLGA) and poly(ethylene vinyl acetate) (PEVA) forms a homogeneous liquid in an organic solvent such as tetrahydrofuran, and a phase-separated PLGA/PEVA composite can be prepared from it by evaporating the organic solvent. Exploiting this phenomenon, we designed a novel method of preparing a drug-loaded PLGA/PEVA composite and used it for coating drug-e...

This work investigates the impact of biomechanical wear and abrasion on the antibiotic release profiles of hydroxyapatite (HA) coated fixation pins during their insertion into synthetic bone. Stainless steel fixation pins are coated with crystalline TiO2 by cathodic arc evaporation forming the bioactive layer for biomimetic deposition of Tobramycin containing HA. Tobramycin is either introduced...

To develop a method that can maintain egg freshness during practical storage conditions, eggs were coated with chitosan and stored with or without dry ice. The physicochemical and microbiological qualities of eggs were evaluated during 14 d of storage at 4 and 23°C without dry ice and at 23°C with dry ice. The combination of chitosan coating and dry ice significantly inhibited a Haugh unit decr...

Effects of various metal coating (Co, Ti, Pd, W, and Ru) on electronic structures of carbon nanotubes are systematically studied by both ab initio calculations and field-emission experiments. The theoretical results indicate that the adsorption of metal atoms leads to substantial changes in the band structures and work functions of nanotubes. In particular, titanium is found to be the most effe...

A number of mater ia ls and techniques have been used t o form se lec t ive s o l a r absorber coatings. Each of the coating processes and the coatings formed has i t s own l imi ta t ions which a r e generally paorly defined. The poor s t a t e of knowledge on the l i m i t a t i o n s of the coating processes and the resu l t ing coatings poses a problem f o r the component design and the mat...

In order to study the wear resistance and corrosion of a composite material with Fe316L substrate Co-Cr-WC coating, Co-Cr alloy coatings different mass fractions WC (hard tungsten carbide) were prepared on by laser cladding technology. The phase composition, microstructure element distribution analyzed X-ray diffraction (XRD), scanning electron microscopy (SEM) energy dispersive spectroscopy (E...

We performed thin carbonate-containing apatite (CA) coating on titanium (Ti) by an aqueous spray coating (ASC) method that consisted of a Ca-CO₃-PO₄ complex. Two different CA coatings were produced by two different spray amounts and were heat-treated after spraying. We evaluated three-dimensional structures, adhesiveness to Ti, and durability of the CA film. In addition, we performed immersion ...

Investigating the interaction patterns at nano-bio interface is a key challenge for safe use of nanoparticles (NPs) to any biological system. The study intends to explore the role of interaction pattern at the iron oxide nanoparticle (IONP)-bacteria interface affecting antimicrobial propensity of IONP. To this end, IONP with magnetite like atomic arrangement and negative surface potential (n-IO...
