C. Q. RuA simplified model is proposed to calculate reduced self-attractive energy of a free monolayer graphene sheet due to ripples. The model admits stable periodic ripple mode of a free-standing graphene ribbon in the absence of a substrate or mechanical stress, and the predicted wavelengths are in rob ... [Appl. Phys.

Jun-yao Wang, Zheng Xu, and Yong-kui Li et al.In this paper, the nanopore density effect on ion enrichment is quantitatively described with the ratio between electrophoresis flux and electroosmotic flow flux based on the Poisson-Nernst-Planck equations. A polyacrylamide gel plug is integrated into a microchannel to form a micro-nanofluidic ch ... [Appl. Phys. Lett. 103, 043103 (2013)] published Mon Jul 22, 2013.

Jason K. King, Brian K. Canfield, and Lloyd M. DavisA microfluidic device with four electrodes in a tetrahedral arrangement is used to demonstrate three-dimensional (3D) trapping of an individual 40 nm fluorescent nanoparticle in solution. Astigmatic imaging is used to determine the particle position in 3D for real-time control of the electrode pot ... [Appl. Phys. Lett. 103, 043102 (2013)] published Mon Jul 22, 2013.

Ioannis Chatzakis, Philippe Tassin, and Liang Luo et al.Emerging technology based on artificial materials containing metallic structures has raised the prospect for unprecedented control of terahertz waves. The functionality of these devices is static by the very nature of their metallic composition, although some degree of tunability can be achieved b ... [Appl. Phys. Lett. 103, 043101 (2013)] published Mon Jul 22, 2013.
