In this study CuO nano sheets were prepared using the cellulose extracted from green synthesis (cotton) as a novel me project. Structural properties were examined using X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), and Ultra Violet (UV-Vis). The optimum copper oxide peak was at 2 theta 〖35.44〗^°corresponding to (1 ̅11) while for the cellulose was 〖22.8〗^°correspon...

Ag nanowire (NW) films obtained by the spraying the Ag NWs on the substrates were nano-welded by rapid thermal annealing (RTA) process and the effect of RTA process on the change of sheet resistance and optical transmittance of the Ag NW films was investigated. The increased number of Ag NW sprays on the substrate decreased the sheet resistance but also decreased the optical transmittance. By t...

BACKGROUND Though the transplantation of in vitro expanded human corneal endothelial precursors in animal models of endothelial damage by injecting into the anterior chamber has been reported, the practical difficulties of accomplishing such procedure in human patients have been a hurdle to clinical translation. Here we report the successful transplantation of in vitro expanded human corneal pr...

A novel bath lily-like graphene sheet-wrapped nano-Si composite synthesized via a simple spray drying process exhibits a high reversible capacity of 1525 mAh g(-1) and superior cycling stability, which could be attributed to a synergistic effect between highly conductive graphene sheets and active nanoparticles in the open nano/micro-structure."

We investigate the motion of a nano tippe top, which is formed from a C60 fullerene, and which is assumed to be spinning on either a graphene sheet or the interior of a single-walled carbon nanotube. We assume no specific geometric configuration for the top, however for example, the nano tippe top might be formed by joining a fullerene C60 with a small segment of a smaller radius carbon nanotub...

An integral equation is formulated to describe electromagnetic wave transmission through a subwavelength nano-hole in a thin plasmonic sheet in terms of the dyadic Green's function for the associated Helmholtz problem. Taking the subwavelength radius of the nano-hole to be the smallest length of the system, we have obtained an exact solution of the integral equation for the dyadic Green's funct...

background:  ramsar, a northern city in iran, lies on the coast of the caspian sea. this city has areas with some of the highest levels of natural radiation measured to date. the radon concentration in some areas of ramsar is up to 3700 bq m–3. on the other hand, due to high level of humidity, damp-proof barriers should be used in construction of new buildings in radon prone areas of this city....

Shape and size of the synthesized NiO nano-sheets were retained during transformation of sheet-like b-Ni(OH)2 to NiO at elevated temperatures via nano-sized zirconia coating on the surface of b-Ni(OH)2. The average grain size was 6.42 nm after 600 C treatment and slightly increased to 10 nm after 1000 C treatment, showing effective sintering retardation between NiO nano-sheets. The excellent th...
