Objective To compare the accuracy and feasibility of methylene blue and nano-carbon in clinical tracing of sentinel lymph nodes (SLNs) in patients with papillary thyroid cancer (PTC). Methods Ninety-six PTC patients were selected and randomly divided into a methylene blue group and a nano-carbon group (n=48). During surgery, tracer agent was injected around the tumor, and SLNs were resected a...

The complex and nano-structured amorphous carbon as p-type films prepared from natural palm oil precursor for heterojunction solar cell were presented. Field-emission scanning electron microscopy (FESEM) revealed the nano structured films had particle size in the range of 28 to 34 nm. The energy-dispersive spectroscopy (EDS) showed the existing of carbon in complex-structured amorphous carbon f...

A nano-composite powder composed of silica and carbon with a unique property could be prepared from a mixture of a silicate compound and an epoxy compound, in which the silica within the nano-composite powder has a BET surface area of as high as greater than 800m2/g although the nano-composite powder has a BET surface area of less than 10m2/g. It was estimated that the silica and the carbon are...

To overcome the problems associated with conventional liposomes in transdermal drug delivery like limited penetration ability and poor stability, in this article we report a new generation of cell penetrating peptide polyarginine containing nano-liposomes conjugated with carbon dots. The newly synthesized, cost-effective liposomic precursors were used for the fabrication of liposomes. The resul...

This paper presents the friction and anti-wear characteristics of nano-oil with a mixture of refrigerant oil and carbon nano-particles in the thrust slide-bearing of scroll compressors. Frictional loss in the thrust slide-bearing occupies a large part of total mechanical loss in scroll compressors. The characteristics of friction and anti-wear using nano-oil is evaluated using a thrust bearing ...

In this study, methane-ethylene jet diffusion flames modulated by acoustic excitation in an atmospheric environment were used to investigate the effects of acoustic excitation frequency and mixed fuel on nanomaterial formation. Acoustic output power was maintained at a constant value of 10 W, while the acoustic excitation frequency was varied (f = 0-90 Hz). The results show that the flame could...

the electronic and structural properties of pristine and carbon doped (c-doped) boron nitride nano-ribbons(bnnrs) have been studied employing density functional theory (dft) calculations. total energies, gapenergies, dipole moments, and quadrupole coupling constants (qcc) have been calculated in the optimizedstructures of the investigated bnnrs. the results indicated that the stability and gap ...

The stability of Ni, Cu, Mo and Au transmission electron microscope (TEM) grids coated with ultra-thin amorphous carbon (alpha-C) or silicon monoxide film is examined by in-situ heating up to a temperature in the range 500-850 degrees C in a transmission electron microscope. It is demonstrated that some grids can generate nano-particles either due to the surface diffusion of metal atoms on amor...

An explicit derivation of dispersion relations and spectra for periodic Schrödinger operators on carbon nano-structures (including graphene and all types of single-wall nano-tubes) is provided.

Noble metal nanoslit structure has attracted an increasing interest in nanoscale photonic devices, and bio applications. However, methods typically used for fabricating nano-sized slit, such as, e-beam direct etching, template-assisted photolithography, and nano-imprint lithography, have low yield and are limited to sub-nano sized slit. In this work, we observed that slit width of Au metal is g...
