Polycrystalline films are used in a wide array of microand nano-scale devices, for electronic, mechanical, magnetic, photonic and chemical functions. Increasingly, the properties, performance, and reliability of films in these systems depend on nano-scale structure. In collaborative research with a number of SMA Fellows, Associates, and students, our group is carrying out research focused on pr...

A mini-review of microfluidic technologies for the generation and manipulation biomimetic nano-assemblies, including perspectives future research directions.

We succeeded in fabrication of a free accessible microchannel using an air-liquid interface. To pattern the air-liquid interface in the microfluidic chip, we utilized nano-geometric surface which encloses micropatterned massive nanopillars to enhance the wettability of the surface, which was fabricated by using the hybrid mask lithography technique. Novelties of this paper are shown as follows....

in this paper, eringen’s nonlocal elasticity and timoshenko beam theories are implemented to analyze the bending vibration for non-uniform nano-beams.  the governing equations and the boundary conditions are derived using hamilton’s principle. a generalized differential quadrature method (gdqm) is utilized for solving the governing equations of non-uniform timoshenko nano-beam for pinned-pinned...

An analytically compact model for the nano-scale double gate MOSFET based on McKelvey’s flux theory is developed. The model is continuous above and below threshold and from the linear to saturation regions. Most importantly, it describes nano-scale MOSFETs from the diffusive to ballistic regimes. In addition to its use in exploring the limits and circuit applications of double gate MOSFETs, the...

the effect of geometry and material of the micro/nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. hertz contact model simulation for eph biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. then, to validat...

Manipulation of Ag nanocrystals derived from up to 200 000 atoms was performed using the tip of a scanning tunneling microscope. By varying the scanning conditions, it was possible to move them laterally on contamination-free Si~111!-737 surfaces or to remove them. In both cases, thin Ag tracks were left behind. This demonstrates the concepts of nano patterning and nano painting with metals on ...
