Highly loaded polymer/clay nanocomposites with layered structures are emerging as robust fire retardant surface coatings. However, time-intensive sequential deposition processes, e.g. layer-by-layer strategies, hinders obtaining large coating thicknesses and complicates an implementation into existing technologies. Here, we demonstrate a single-step, water-borne approach to prepare thick, self-...

Coral Pt islands films are deposited via electrochemical reduction on silica-coated nanostructured Ag electrodes. From these devices surface-enhanced (resonance) Raman [SE(R)R] signals of molecules exclusively attached to Pt are obtained with intensity up to 50% of the value determined for Ag. SE(R)R spectroscopic investigations are carried out with different probe molecules, silica-coating thi...

Immediate loading of dental implants is only possible if a firm bone-implant anchorage at early stages is developed. This implies early and high bone apposition onto the implant surface. A nanostructured coating material based on an osseoinductive bone grafting is investigated in relation to the osseointegration at early stages. The goal is to transmit the structure (silica matrix with embedded...

Roll-To-Roll Slot-Die Coating In article number 2212835, Jens Wenzel Andreasen and co-workers study the optical excitation during roll-to-roll slot-die coating of a semiconducting polymer that enables morphological manipulation thin-films for organic photovoltaics flexible electronics. Combined theoretical experimental techniques elucidate changes upon while thin-film solidifies. The induced in...

Coating characteristics such as composition, crystallite features and topography collectively impact the cell response. The influence from splats has not yet been assessed for hydroxyapatite (HAp) thermal spray coatings. The objective of this work is to (a) survey the topography on commercial implants, (b) ascertain topography formation from single splats, and (c) determine the osteoclast resor...

We report on the first experimental realization of a high-reflectivity cavity mirror that solely consists of a single silicon crystal. Since no material was added to the crystal, the urgent problem of "coating thermal noise" that currently limits classical as well as quantum measurements is avoided. Our mirror is based on a surface nanostructure that creates a resonant surface waveguide. In ful...

This paper discusses the results of a study focused on nature interaction Me-MeN-(Me,Mo,Al)N coatings (where Me = zirconium (Zr), titanium (Ti), or chromium (Cr)) with contact medium based Ni-Cr system. The studies were carried out during turning nickel–chromium alloy at different cutting speeds. hardness was found, and their nanostructure phase composition studied. experiments conducted using ...

Electrically conductive amorphous carbon nitride (a-CN) coatings were deposited onto various substrates by pulsed vacuum-arc sputtering of a graphite cathode with simultaneous irradiation the substrate nitrogen ions. Deposition temperature was less than 60 °C. We investigated effect vacuum annealing at 600°С on elemental composition, structure, electrical and optical properties obtained films. ...

In this work, a simple and effective way to modify the support surface is developed and a nanostructure ceramic support to facilitate deposition of a defect-free overlying micro and meso (nano) porous membrane is obtained. To achieve high performance nanocomposite membranes, average pore size of outer surface of support was reduced by dip-coating in submicron and nano α-alumina slurries. In...
