Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology
Advanced Engineering Materials, EarlyView.We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Power scaling of tunable, narrowband, non-resonant PPLN optical parametric oscillators
Journal of the European Optical Society-Rapid PublicationsWe review our recent achievements with narrowband, nanosecond, non-resonant optical parametric oscillators based on periodically-poled LiNbO3, which are pumped at 1064 nm and emit close to degeneracy in the near-IR part of the spectrum between 1860 and ...

Advanced Engineering Materials, EarlyView.Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Nonlinear optics in a birefringent optical fiber
Physical Review E, 2004 We extend the perturbation theory of the nonlinear Schrödinger equation for the study of perturbed (nonintegrable) forms of the vector equation. We derive a set of linear equations that describe the radiation field shed by the soliton as it propagates down a birefringent optical fiber.

Intermediate Models in Nonlinear Optics [PDF]
SIAM Journal on Mathematical Analysis, 2005 This paper deals with models for the simulation of the propagation of laser pulses in a nonlinear medium. The new model turns out to be exact in linear cases, but take into account the nonlinear effects; some numerical results are presented to illustrate the error bounds and to investigate the numerical effectivity of the model.

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.
