We provide the first demonstration of exceptional light-with-light optical switching performance of a carbon nanotube metamaterial - a hybrid nanostructure of a plasmonic metamaterial with semiconducting single-walled carbon nanotubes. A modulation depth of 10% in the near-IR with sub-500 fs response time is achieved with a pump fluence of just 10 μJ/cm², which is an order of magnitude lower th...

Fossil fuels are the main sources of human energy, but their combustion releases toxic compounds sulfur oxide. In oil industry, using optimal methods to eliminate from fossil is a very important issue. this study, performance montmorillonite/graphitic carbon nitride (a new hybrid nanostructure) in increasing biodesulfurization activity Rhodococcus erythropolis IGTS8 was investigated. X-ray diff...

This paper gives an overview of our recent work on freely suspended layer-by-layer nanomembranes containing organized arrays of nanostructures such as carbon nanotubes or gold nanoparticles. These unique organized arrays toughen the membrane and add interesting optical properties which are useful in sensor applications. Gold nanoparticle encapsulated nanomembranes were characterized by surface ...

The microstructure characterization of tempered nanocrystalline bainitic steel is investigated in the present study. It is found that two types of plastic relaxation, dislocation debris and nanotwin, occurs in the displacive transformation due to relatively low transformation temperature and high carbon content. Because most carbon atoms trap in the dislocation, high dislocation density can be ...

Carbon-based nanostructures have attracted extensive interest in obtaining advanced sensing electronic devices environmental and biological monitoring applications as an alternative to conventional materials. Herein, the facile preparation, control of growth, artificial intelligence–based morphological information carbon nanopillar array Anodized Aluminum Oxide (AAO) template were investigated....

BACKGROUND Recent advances in developing biocompatible materials for treating bone loss or defects have dramatically changed clinicians' reconstructive armory. Current clinically available reconstructive options have certain advantages, but also several drawbacks that prevent them from gaining universal acceptance. A wide range of synthetic and natural biomaterials is being used to develop tiss...

The evolution of silica nanostructure morphology induced by local Si vapor source concentration gradient has been investigated by a smart design of experiments. Silica nanostructure or their assemblies with different morphologies are obtained on photoresist-derived three-dimensional carbon microelectrode array. At a temperature of 1,000°C, rope-, feather-, and octopus-like nanowire assemblies c...
