Research Highlights : Determination and characterization of effects of surface defects and tips on optical properties Abstract : Effects on the optical properties of gold nanospheres are investigated by using discrete dipole approximation (DDA) with respect to variations of
Direct Simulation Monte Carlo for Dense Hard Spheres
Research Highlights : Application through modifying DSMC method on dense gas system Abstract : We propose a modified direct simulation Monte Carlo (DSMC) method, which extends the validity of DSMC from rare¯ed to dense system of hard spheres (HSs).
Mechanical behavior of metal nanoplates
Research Highlights : We are studying various mechanical responses of nanoplates due to the surface effect, such as ultrahigh strength, negative Poisson’s ratio, intrinsic instability, initiation of plasticity, large induced compressive stresses Abstract : The Poisson’s ratio is a fundamental
Stacked carbon electrode based electrochemical/biosensor platform
Research Highlights : 3D suspended carbon micro/nano structures were fabricated using batch carbon-MEMS process. A novel suspended morphology of the carbon nanostrucutres enabled highly sensitive electrochemical/biosensing Abstract : Herein, we present a novel electrochemical sensing platform that consists of a
Nanoparticle pattern formation in evaporating droplets
Research Highlights : The mechanism of instabilities of deposit patterns left after the evaporation of a particle-laden liquid droplet was elucidated using a Monte Carlo method Abstract : The characteristics of several patterns left after the evaporation of
