Submicron Metasurface Reconfigured Multiband Smart Windows
Advanced Functional Materials, EarlyView.This work presents a submicron metasurface reconfigured multiband thermochromic smart window. By integrating subwavelength nanostructures into a Fabry−Perot resonator configuration, it mitigates conventional trade‐offs to simultaneously deliver high luminous transmittance and robust solar heating and radiative cooling modulation capabilities ...

, 2017 小型風力發電機由於成本考量與可改裝空間較少之故，大部分都採用無控制或失速控制方式，但因為無法擷取額定風速以上的風能，在發電效率上尚有改進空間，本文旨在發展主動控制2kW小型風力發電機組的設計及實驗原型系統，以改善小型風力發電機的發電性能。 本文以東元2kW被動式小風機為基礎，首先發展創新機構葉片變旋角機構及主動式變旋角控制系統，利用直流伺服馬達驅動葉片傘形齒輪機構，並搭配PID旋角控制器，以一傘齒輪帶動三個從動傘齒輪，改變風機葉片旋角。其次建立小風機的全機系統數學模型，並以FAST ...

Advanced Functional Materials, EarlyView.A shape‐memory microneedle system enables reproductive hormone therapy through a single transdermal insertion. The X‐shaped device sustains follicle‐stimulating hormone release for three days, and mild heating restores the O shape to trigger burst human chorionic gonadotropin release.

Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Advanced Functional Materials, EarlyView.Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward
