Uniform and vertical indium-oxide nanotube (IONT) arrays embedded well in n-type InP single crystal have been successfully prepared in situ by porous InP-template-assisted chemical vapor deposition (CVD). This IONT/InP nanostructure reveals high sensitivity to humidity at room temperature, which is ascribed to the ultrahigh surface-to-volume ratio of this nanostructure and the large number of o...

Investigations in the burgeoning field of nanophotonics have demonstrated that certain nanostructures act in previously unanticipated ways. One such behavior is surface-enhanced Raman scattering (SERS), an area of substantial interest, as demonstrated by the hundreds of scientific papers published on the subject during the past 5 years. SERS was discovered over 3 decades ago.1–3 It transforms t...

in the past decades, many methods have been developed to synthesize zero- dimensional  nanoparticles, quasi–one–dimensional (1d) cuo nanostructures, such as metal organic deposition technique,  microwave irradiation, sol-gel-like dip  technique, reverse micelle-assisted route, chemical method, and simple template free solution route. among those synthesis methods, hydrothermal and chemical reac...

conventional and nanostructured ysz coatings were deposited on the in-738 ni super alloy by the atmospheric plasma spray technique. the oxidation was measured at 1100°c in an atmospheric electrical furnace. according to the experimental results the nanostructured coatings showed a better oxidation resistance than the conventional ones. the improved oxidation resistance of the nanocoating could ...

The construction of hollow nanostructure by compositing with carbonaceous materials is generally considered an effective strategy to mitigate the drastic volume expansion transition metal sulfides (TMSs) high theoretical specific capacity in process lithium storage. However, designing well-controlled architectures extended lithiation cyclic stability, and ease electroactive into reserved spaces...

Nanotechnology is anticipated to open novel opportunities to prevent and fight against diseases using atomic scale tailoring of materials [1-3]. In the field of nanotechnology, the synthesis of nanoparticles of different sizes, shape, chemical compositions and controlled morphology with high dispersityis essential because they exhibit unique properties, which are not observed in bulk materials ...

Liquid atomization is applied in nanostructure dense coating technology to inject suspended nano-size powder materials into a suspension plasma spray (SPS) torch. This paper presents the effects of the atomization parameters on the nanoparticle processing. A numerical model was developed to simulate the dynamic behaviors of the suspension droplets, the solid nanoparticles or agglomerates, as we...

We describe a method to form custom-shaped inorganic oxide nanostructures by using DNA nanostructure templates. We show that a DNA nanostructure can modulate the rate of chemical vapor deposition of SiO2 and TiO2 with nanometer-scale spatial resolution. The resulting oxide nanostructure inherits its shape from the DNA template. This method generates both positive-tone and negative-tone patterns...

The synthesis of a conformal three-dimensional nanostructure based on porous anodic alumina with transversal nanopores on wires is herein presented. The resulting three-dimensional network exhibits the same nanostructure as that obtained on planar geometries, but with a macroscopic cylindrical geometry. The morphological analysis of the nanostructure revealed the effects of the initial defects ...

OBJECTIVE Because of the widespread clinical use of heparins, their effects on the enzymatic cascade are very well known. In contrast, little is known about the direct effect of heparins on the nanostructure of fibrin fibers, even though this nanostructure plays a major role in the mechanical strength and lysis of clots. This lack of reliable data can be correlated with the lack of a nonintrusi...
