Parylene has been used as encapsulation material since several decades, e.g. for wires, needles and pacemaker coatings. Within this paper, its use as insulation and protection layer for flexible biomedical microimplants is described. Investigations on the deposition, structuring with reactive ion etching and the cytotoxic behavior of the etched layers led to promising results. Parylene seems to...

The successful development of multijunction photovoltaic devices with four or more subcells has placed additional importance on the design of high-quality broadband antireflection coatings. Antireflective nanostructures have shown promise for reducing reflection loss compared to the best thin-film interference coatings. However, material constraints make nanostructures difficult to integrate wi...

Metallic orthopaedic implants have been successfully used for decades but they have serious shortcomings related to their osseointegration and the fact that their mechanical properties do not match those of bone. This paper reviews recent advances in the fabrication of novel coatings to improve implant osseointegration and in the development of a new generation of hybrid organic-inorganic impla...

In this study, dimmer-acid-based hybrid nonisocyanate polyurethanes (HNIPUs) were synthesized by the one-step method without catalyst. Three polyamines and two epoxy resins were selected as raw materials for HNIPU, and cyclic carbonate was synthesized based on our previous work. All of the products were characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calor...

Coassembly between block copolymers and nanodiamonds (NDs) leads to transparent UV-protective coatings hybrid superstructures with hierarchical assembly of NDs.

THE USE OF HYBRID OR NANOCOMPOSITE MATERIALS AS STEEL ANTICORROSIVE COATINGS. The search had as the goal to present and reflect hybrid materials an alternative for anticorrosive coatings of metallic surfaces, such steel. For comparison purposes, different types anti-corrosion capable protecting steel, from oxidation action were presented. Steel is a material widely used by industry in segments,...

We theoretically analyze nanowire-based hybrid plasmonic nanocavities on thin substrates at visible wavelengths. In the presence of thin suspended substrates, the hybrid plasmonic modes, formed by the coupling between a metal nanowire and a dielectric nanowire with optical gain, exhibit negligible substrate-mediated characteristics and overlap better with the gain region. Consequently, the conf...
