The interaction of electromagnetic radiation in X and Ka bands with magnetic nanocomposite disordered carbon nanotubes arrays has been investigated both experimentally theoretically. Samples were synthesized on the quartz reactor walls by decomposition ferrocene xylene which provided random intercalation iron phase nanoparticles nanotube array. exhaustive characterization samples means scanning electron microscopy, Raman spectroscopy, x-ray photoemission spectroscopy was performed. It found...
We present Raman studies of graphene films grown on copper foil by atmospheric pressure CVD with n-decane as a precursor, mixture nitrogen and hydrogen the carrier gas, under different flow rates. A novel approach for processing spectroscopy data was employed. It found that in particular cases, various parameters spectra can be assigned to fractions thicknesses. In particular, such quantities full width at half maximum 2D peak position band were successfully applied elaborated approach. Both...
Liver cancer is one of the malignant tumors with highest fatality rate and increasing incidence, which has no effective treatment plan. Early diagnosis early liver play a vital role in prolonging survival period patients improving cure rate. Carcinoembryonic antigen (CEA) alpha-fetoprotein (AFP) are two crucial tumor markers for diagnosis. In this work, we firstly proposed wafer-level, highly controlled silicon nanowire (SiNW) field-effect transistor (FET) joint detection sensor sensitive...
Tall, crystalline carbon nanotubes (CNTs) are desired to successfully integrate them in various applications. As the crystallinity of CNTs improves with increasing growth temperatures, higher temperatures required obtain CNTs. However, a typical chemical vapor deposition (CVD) process, CNT rate reduces when temperature exceeds specific level due degradation catalyst particles. In this study, we have demonstrated improved catalytic activity nickel/ferrocene-hybridized as compared sole...
The airflow sensor enabled by triboelectric nanogenerator (TENG) is significant for intelligent lab safety and human–computer interaction applications.

Few-wall carbon nanotubes were synthesized by methane/acetylene decomposition over bimetallic Fe-Mo catalyst with MgO (1:8:40) support at the temperature of 900°C. No calcinations and reduction pretreatments applied to catalytic powder. The transmission electron microscopy investigation showed that [CNTs] have high purity narrow diameter distribution.

The influence of the magnetic medium can lead to peculiar interaction between ferromagnetic nanoparticles (NPs). Most research in this area involves analysis interplay anisotropy and exchange coupling. Increasing average interparticle distance leads dominant role random anisotropy. Here we study a carbon nanotube (CNT) matrix with low NP content. Samples were synthesized by floating catalyst chemical vapor deposition. We found that below some critical concentration, when NPs are intercalated...

Sol-gel technology has attracted attention in the fabrication of diverse luminescent materials and thin film structures, with forms that range from powders to microcavities. The optical properties sol-gel-derived structures depend on sol composition, deposition, heat treatment conditions, as well thicknesses other factors. Investigations upconversion luminescence lanthanides are also ongoing. In this study, we synthesized three different types using same sol, which corresponded a...

It has been widely reported that carbon nanotubes (CNTs) exhibit superior field emission (FE) properties due to their high aspect ratios and unique structural properties. Among the various types of CNTs, random growth CNTs promising FE reduced inter-tube screening effect. However, growing on individual catalyst islands often results in spread out CNT bundles, which reduces overall enhancement. In this study, significant improvement bundles is demonstrated by confining them microfabricated...
