Advanced Functional Materials, EarlyView.A hybrid photoprotective material integrates N‐doped TiO2 with a metal‐phenolic network (MPN) to achieve broad‐spectrum attenuation and robust reactive oxygen species (ROS) suppression. Nitrogen doping extends attenuation into the UVA/high energy visible light (HEV) regions and facilitates fast charge recombination to inhibit ROS formation.

Ultrawide Bandwidth Optomechanical Magnetometry Using Flux Concentration
Advanced Functional Materials, EarlyView.High‐permeability flux concentrators enable ultrawide‐bandwidth chip‐scale optomechanical magnetometry by exploiting magnetic nonlinearity to up‐convert low‐frequency fields to the mechanical resonance, where sensitivity is optimal. This enables flat wideband operation over more than four orders of magnitude, from tens of kilohertz to sub‐hertz ...

Design of Broadband and Multiband Dielectric Resonator Antennas [PDF]
, 2007 本論文主要是設計寬頻及多頻介質共振器天線，可應用於寬頻無線通訊系統。 在此論文中，我們在介質共振器內插入一空隙，以增強電場強度，提高輻射效率，而使頻寬增加。或挖一溝槽，擾動原本的電磁場分佈，降低共振器之品質因子，而達到寬頻的效果。利用此概念設計一雙頻介質共振器天線，可符合WiMAX與WLAN之規格。 在此論文中，我們也設計一介質共振器天線，使共振器之TEy111、TEy112、與TEy113的共振頻率互相靠近，利用孔隙耦合的方式饋入，以結合三個共振頻帶而達到寬頻的效果，並在介質共振器內部挖一溝槽 ...
