From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits
Advanced Science, EarlyView.This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Advanced Science, EarlyView.An electronics‐free smart scleral lens passively monitors dry eye disease‐related tear biomarkers through colorimetric sensing of chloride, pH, and ocular surface temperature. Smartphone‐assisted image analysis enables quantitative interpretation, providing a simple, non‐invasive strategy for ocular health monitoring without integrated electronics ...

Dielectric relaxation of poled polymer DCNP/PMMA
, 2000 We have prepared the polymer thin films of a 3-(1,1-dicyanothenyl)-1-phenyl-4,5-dihydro-1H-pyrazole (DChTP)/poly (methyl methacrylate) (PMMA) guest-host system by spin coating.

Programmable Sequential 4D Actuation in Multistable Kirigami Metamaterials
Advanced Science, EarlyView.This study presents a modular kirigami metamaterial framework enabling programmable multistability and sequential 4D actuation. By coupling geometry‐controlled multistability with material‐dependent recovery kinetics, spatiotemporal deformation can be precisely programmed.

Membrane Preparation of PVDF/PMMA Blends and Its Physical Properties
, 2014 聚偏二氟乙烯（PVDF）/聚甲基丙醯酸甲酯（PMMA）為相容性極高，而且一般在融態時，被視為是互溶的高分子。本研究以乾式成膜程序，配製緻密形態的薄膜。利用場放射電子顯微鏡（FESEM），調頻微分掃描熱卡計（M-DSC）、及寬角度X光繞射（XRD）探討PVDF與PMMA摻混系統之熱性質與相行為。發現其玻璃轉移溫度有很大的，互相靠近的偏移。摻合體中PMMA玻璃轉移溫度，出現熱行為的鬆弛現象。摻合體薄膜在低於PMMA的玻璃轉化溫度下，約50oC的環境進行退火。隨退火時間的增長，熱行為的鬆弛顯出趨緩的現象 ...

Atomistic Kinetics of Dislocation‐Mediated Grain Growth in Monolayer MoS2
Advanced Science, EarlyView.Atomic‐resolution in‐situ heating microscopy directly visualizes dislocation‐mediated grain boundary migration and grain growth in monolayer MoS2. Mobile grain boundaries migrate through collective motion of Mo 5|7 dislocations, whereas S 5|7 defects remain largely immobile.

Advanced Science, EarlyView.This work is the first to demonstrate the regulation of photoactivated room‐temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) in crystalline materials without any pretreatment. Furthermore, we reveal the underlying mechanisms by uncovering the role of host‐guest energy level alignment, exciton lifetime, crystallinity,
