nano materials have been widely used in laboratory and industrial scales in order to improve various properties of concrete and concrete mixture. the mainstream practice of the researches in this field is to add metallic nano-particles into the concrete mixture. the present research focuses on adding micro-nano air bubbles (mnab) into water before mixing it with aggregate and cement mixtures. i...

The properties of metallic clusters of various shapes, on the nanometer length scale, can be dramatically different from the corresponding bulk material due to their very large surface-to-volume ratio. The unique optical and mechanical properties of such nanoclusters hold great promise for the development of nanotechnology. Gold nanoclusters, for example, have found application in such diverse ...

Radiation patterns of linear chains of metallic nano-particles (nano-antennae) in the proximity of a hetero-interface of two media with different refractive indices are studied theoretically. We propose to excite the system by evanescent waves in which case the excitation does not interfere with the radiated signal. We show that the radiation pattern of such antennae can be very anisotropic and...

The work proposed a novel thermoplastic forming approach-the ultrasonic beating forming (UBF) method for bulk metallic glasses (BMGs) in present work. The rapid forming approach can finish the thermoplastic forming of BMGs in less than one second, avoiding the time-dependent crystallization and oxidation to the most extent. Besides, the UBF is also proved to be competent in the fabrication of s...

We discuss the manifestation of dynamical symmetries in quantum transport through nanostructures. The dynamical symmetry SO(4) manifested in the singlet-triplet excitations is shown to be responsible for several exotic effects in nano-devices: non-equilibrium Kondo effect in T-shape Double Quantum Dots, phonon-induced Kondo effect in transition-metal-organic complexes, Kondo shuttling in Nano-E...

Arrays of plasmonic pentamers consisting of five metallic nano-disks were designed and fabricated to achieve a pronounced Fano Resonance with polarization-independent far-field spectral response at normal incidence due to the structure symmetry of pentamers. A mass-spring coupled oscillator model was applied to study plasmon interactions among the nano-disks. It was found that the direction of ...

Bulk metallic glass matrix composites (BMGMCs) are a new class of metal alloys which have significantly increased ductility and impact toughness, resulting from the ductile crystalline phases distributed uniformly within the amorphous matrix. However, the 3D structures and their morphologies of such composite at nano and micrometre scale have never been reported before. We have used high densit...

Dielectrophoresis is an efficient technique often used to handle or trap micro-/nano-particles within microfluidic devices. For that purpose, arrays of insulating materials disposed between polarization electrodes are classically used to generate the necessary dielectrophoresis forces. In this paper, a novel method is proposed where metallic micro dots are arrayed to generate strong field inhom...
