Inspired by biosilicification, biomimetic polymer-silica nanocomposite has aroused a lot of interest from the viewpoints of both scientific research and technological applications. In this study, a novel dual functional polymer, NH₂-Alginate, is synthesized through an oxidation-amination-reduction process. The "catalysis function" ensures the as-prepared NH₂-Alginate inducing biomimetic mineral...

Polymer nanocomposites have recently been attracting attention among researchers in electrical insulating applications from energy storage to power delivery. However, partial discharge has always been a predecessor to major faults and problems in this field. In addition, there is a lot more to explore, as neither the partial discharge characteristic in nanocomposites nor their electrical proper...

A technique for the formation of gelatin thin films and composite coatings with silicon dioxide zinc oxide nanoparticles by spin coating has been developed. New data morphology structural characteristics formed nanocomposite were obtained atomic force microscopy. The dependences roughness parameters on content in polymer matrix are presented. It shown that introduction inorganic into structure ...

The multi-scale finite element method is used to study the vibrational characteristics of polymer matrix reinforced by single-walled silicon carbide nanotubes. For this purpose, the nanoscale finite element method is employed to simulate the nanotubes at the nanoscale. While, the polymer is considered as a continuum at the larger scale. The polymer nanotube interphase is simulated by spring ele...

Multiplexed analysis allows researchers to obtain high-density information with minimal assay time, sample volume and cost. Currently, microcarrier or particle-based approaches for multiplexed analysis involve complicated or expensive encoding and decoding processes. In this paper, a novel optical encoding technique based on nano-silicon dioxide film is presented. Microcarriers composed of ther...

Recent research on biodegradable magnesium-based implants has been focusing increasing their mechanical strength and controlling corrosion rate. One promising approach to significantly improve the properties of magnesium is addition nanoparticles matrix. However, there limited behavior these new nanocomposites. In this study, electrochemical characteristics class biomaterials are investigated. ...

A silicon micromachining method that is able to create deep silicon dioxide blocks at selected locations in a silicon substrate is presented. The process combines deep-reactive-ion etching (DRIE), thermal oxidation, deposition of silicon dioxide and optional planarization. Design issues and parameters for the creation of such blocks are discussed. The selectively defined silicon dioxide blocks ...
