To determine the non-bonded interaction energies between Naphthalene and B12N12 Nano ring in different orientations and distances, geometry of molecules with B3LYP method and 6-31g* basis set optimized. Also reactivity and stability of Naphthalene alone and in the presence B12N12 Nano ring checked. Then calculated the NBO, NMR, FREQ, NICS and muliken charge of Naphthalene atoms alone and in the...

The feasibility of using gold nano-rings as plasmonic nano-optical tweezers is investigated. We found that at a resonant wavelength of λ=785 nm, the nano-ring produces a maximum trapping potential of ~32k(B)T on gold nanoparticles. The existence of multiple potential wells results in a very large active volume of ~10(6) nm(3) for trapping the target particles. The report nano-ring design provid...

we design a novel nano-ring resonator using two-dimensional photonic crystal (2d-phc), for bio-sensing applications. the structure of biosensor is created by two-curve-shaped ring resonator which sandwiched by two waveguides. these are configured by removing one row of air holes. the refractive index of sensing hole is changed by binding an analyte. hence, intensity of the transmission spectrum...

Introduction Various forms of carbon nanomaterials such as fullerenes, carbon nanotubes, Nano diamonds and other carbon nanomaterial’s have been rapidly developed not only for their unusual electrical and mechanical properties, but also for their potential use in Nano fluidic device [1-9]. Since 2003 Kawase et al. [10] reported the synthesis of the first Nano rings, a family of similar material...

This paper reports a nano-opto-mechanical pressure sensor based on nano-scaled ring resonator. The pressure is measured through the output spectrum shift which is induced via mechanical deformation of the ring resonator. The sensitivity as high as 1.47 pm/kPa has been experimentally achieved which agrees with numerical prediction. Due to the strong variation of sensitivity with different ring r...

epoxides undergo regioselective ring opening with various nucleophiles using catalytic amount of nano magnesium oxide and water as solvent under mild reaction conditions. the remarkable features of this method are improved yields, high regioselectivity, and green chemistry agreement.

A continuum theory is used to study the effects of homeotropic nano-particles on degenerate planar liquid crystal interfaces. Particle self-assembly mechanisms are obtained from careful examination of particle configurations on a planar film and on a spherical droplet. The free energy functional that describes the system is minimized according to Ginzburg-Landau and stochastic relaxations. The ...

Generic approaches to nano-dots and nano-rings have been developed via sputtering an Au layer on one planar surface side of porous anodic aluminum oxide template and subsequent electrodeposition.
