Anisotropic Second‐ and Third‐Harmonic Hermite–Gaussian Beam Generation with NbOI2 Holograms

open access: yesAdvanced Photonics Research, EarlyView.
Anisotropic second‐ and third‐harmonic Hermite–Gaussian (HG) beam generation is demonstrated with ultrathin NbOI2 grating holograms to produce the nonlinear HG01 and HG10 modes with high anisotropy ratios. The relative magnitudes of the second‐ and third‐order nonlinear susceptibility tensor elements of NbOI2 crystal are extracted. These demonstrations

Nonlinear convection in reaction-diffusion equations under dynamical boundary conditions

open access: yesElectronic Journal of Differential Equations, 2013
We study the blow-up phenomena for positive solutions of nonlinear reaction-diffusion equations including a nonlinear convection term $partial_t u = Delta u - g(u) cdot abla u + f(u)$ in a bounded domain of $mathbb{R}^N$ under the dissipative ...

Design Optimization of a Variable Stiffness Robotic Gripper with Passive Restoration Fabricated by Multimaterial 3D Printing

open access: yesAdvanced Robotics Research, EarlyView.
A multimaterial robotic gripper fabricated via multimaterial 3D printing integrates conductive thermopolymer joints with flexible elastomeric components. Joule heating enables precise joint‐level stiffness modulation, enhanced by embedded temperature sensors, passive shape restoration, and active cooling, enabling versatile manipulation capabilities ...

Nanomaterial‐Based Optical Biosensors for SARS‐CoV‐2 Detection: A Retrospective of the Pandemic

open access: yesAdvanced Sensor Research, EarlyView.
This review discusses nanomaterial‐based optical biosensors developed for or adapted to the detection of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). It concludes by providing a perspective on how lessons learned during the coronavirus disease of 2019 (COVID‐19) pandemic may be applied for future research on nanomaterial‐based ...
