"Biomimetic" approaches for heterogeneous growth of inorganic coatings have become particularly widespread in biomedical applications, where calcium phosphate (CaP) mineral coatings are used to improve biomedical implants. Changes in coating properties can influence the effects of mineral coatings on adjacent cells, but to date it has not been practical to systematically vary inorganic coating ...

This article reviews the present state of the art in the field of flexible antibacterial coatings which efficiently kill bacteria on their surfaces. Coatings are formed using a reactive magnetron sputtering. The effect of the elemental composition and structure of the coating on its antibacterial and mechanical properties is explained. The properties of Cr-Cu-O, Al-Cu-N, and Zr-Cu-N antibacteri...

Si and N-doped DLC coatings with various Si and N contents were prepared using a magnetron sputter ionplating technology. The antifouling property of DLC coatings was evaluated with Pseudomonas fluorescens which is one of the most common bacteria forming biofilms on the surface of heat exchangers in cooling water systems. The experimental results showed that bacterial removal by a standardised ...

No prior research has documented the different types of rock coatings in Yosemite Valley, despite the evident black streaks down Yosemite Falls, the light granitic rock exposed by recent rock falls contrasting with dark rock coatings, and the millions of visitors who have photographed the coated rocks of Yosemite. This paper identifies the types of rock coatings found on Half Dome, in Yosemite ...

Microcapsules have received a great deal of attention from researchers due to their excellent properties, and are commonly prepared by interfacial in situ polymerisation methods. In is an important method microcapsule preparation, which has number advantages such as low cost suitability for industrial production. Microencapsulation used modify the state material order improve its practical usab...

Micro-arc oxidation (MAO) ceramic coatings were formed on TC4 alloy surface in silicate and metaphosphate electrolytes based with K₂ZrF₆ for various concentrations. X-ray diffraction (XRD), Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) were used to characterize the phase composition, microstructure and chemical compositions of the coatings. The infrared emissivity o...

Significant research has been devoted to the development of hydroxyapatite (HA) as a coating material for metallic biomaterials used in bioimplants where the biocompatibility is provided by HA while the mechanical properties of the implant are confirmed by the metallic substrates. The in vitro tests of these coatings have conducted by soaking in simulated body fluid (SBF) solutions to evaluate ...

Coatings of the Mg(OH)2/Mg-Al layered double hydroxide (LDH) composite were formed by a combined co-precipitation method and hydrothermal process on the AZ31 alloy substrate in alkaline condition. Subsequently, a superhydrophobic surface was successfully constructed to modify the composite coatings on the AZ31 alloy substrate using stearic acid. The characteristics of the composite coatings wer...

A choice-based conjoint study was conducted sampling 400 individuals to determine their preference for Soft Touch and raised tactile coatings, which are sometimes called Hi Rise or profile coatings. Soft Touch coatings have a velvety, warm feel to them, and Hi Rise coatings simulate embossing with a glossy appearance to them. Both are considered tactile coatings, engaging the sense of touch. De...

To prevent Cr poisoning of the cathode and to retain high conductivity during solid oxide fuel cell (SOFC) operation, Cu or La doped Co-Mn coatings on a metallic interconnect is deposited and followed by oxidation at 750 ◦C. Microstructure and composition of coatings after preparation and oxidation is analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). High energy micro ...
