A new simple and cheap method to grow large scale SiC-SiO2 nanocables on catalyzed Si substrate directly is presented. The method is based on the thermal decomposition of methanol. The grown nanocables consisted of crystalline 3C-SiC and amorphous SiO2. A simple etching and oxidation process was used to analyze the contribution of SiC and SiO2 components to photoluminescence.

Novel N-halamine nanoparticles potentially useful for killing pathogenic bacteria, i.e., SiO2@PS/N-halamine NPs, were successfully synthesized via the immobilization of N-halamines onto the polystyrene-coated silica nanoparticles (SiO2@PS NPs). The effect of reaction conditions, i.e., chlorination temperature, bleaching concentration, chlorination time, on the oxidative chlorine content in the ...

Cr2O3 and Cr2O3–SiO2-TiO2 coatings are deposited on P265GH steel using atmospheric plasma spraying. The influence of silicon oxide—titanium oxide addition the surface morphology coatings, phase composition tribological properties under non-lubricated sliding conditions investigated. SiO2-TiO2 led to formation a more uniform reduce roughness coatings. X-ray diffraction (XRD) studies indicated th...

We calculate @ =@n (where chemical potential and n electron density), which is associated with the compressibility, in graphene as a function of n, within the Hartree-Fock approximation. The exchange-driven Dirac-point logarithmic singularity in the quasiparticle velocity of intrinsic graphene disappears in the extrinsic case. The calculated renormalized @ =@n in extrinsic graphene on SiO2 has ...

The light output power of AlGaInP-based vertical-injection light-emitting diodes (VI-LEDs) can be enhanced significantly using n-AlGaInP nanopillars. n-AlGaInP nanopillars, ~200 nm in diameter, were produced using SiO2 nanopillars as an etching mask, which were fabricated from self-assembled tin-doped indium oxide (ITO)-based nanodots formed by the wet etching of as-deposited ITO films. The AlG...

Humans may be exposed to engineered silica nanoparticles (SiO2-NPs) but potential adverse effects are poorly understood, in particular in relation to cellular effects and modes of action. Here we studied effects of SiO2-NPs on cellular function in human hepatoma cells (Huh7). Exposure for 24 h to 10 and 50 μg/ml SiO2-NPs led to induction of endoplasmic reticulum (ER) stress as demonstrated by t...

the aims of the study were to investigate the effect of poly(ε -caprolactone) (pcl) and nano- sio2 within the thermoplastic starch (tps) blends on the rate and extent of starch enzymatic hydrolysis using enzymes α-amylase and amyloglucosidase. the results of this study have revealed that blends with nano-sio2 content at 6 wt% exhibited a significantly reduced rate and extent of starch hydrolysi...

We have studied the electron transport in SiO2(Co)/GaAs and SiO2(Co)/Si heterostructures, where the SiO2(Co) structure is the granular SiO2 film with Co nanoparticles. In SiO2(Co)/GaAs heterostructures giant magnetoresistance effect is observed. The effect has positive values, is expressed, when electrons are injected from the granular film into the GaAs semiconductor, and has the temperature-p...

Background Methylprednisolone (MPS) is an important drug used in therapy of many diseases. However, osteonecrosis of the femoral head is a serious damage in the MPS treatment. Thus, it is imperative to develop new drugs to prevent the serious side effect of MPS. Methods The potential interferences Se@SiO2 nanocomposites may have to the therapeutic effect of methylprednisolone (MPS) were evalu...

In this paper, the optical properties of the multilayer rugate filter by structure of (HL) ^ 9Hhas been investigated.
