Advanced Functional Materials, EarlyView.The polymer wall stabilized dye‐doped liquid crystals (PWLCs) enhance the sensitivity of photoinduced molecular reorientation in dye‐doped LC systems. The PWLC with an invisible polymer wall successfully reduces the threshold intensity and functions as an optical limiter under the incidence of low intensity light laser source.

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells
Advanced Functional Materials, EarlyView.ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

A Probability-based Model for Visual Secret Sharing Schemes without Pixel Expansion
, 2009 視覺密碼是一個密碼學的新興研究領域，它與傳統密碼學的主要差異在於解密過程的不同。視覺密碼的方法是將一份機密影像加密成N份分享影像，參與機密分享的每個人都可以持有一份分享影像。一群被允許還原秘密的人將她們所持有的分享影像重疊在一起後，便可以直接透過肉眼看到機密訊息；而被禁止還原機密訊息的一群人便無法利用分享影像獲得任何機密訊息。視覺密碼學的主要精神在於解密的方法是透過人類視覺系統，而不需使用任何密碼學知識與計算機資源。在視覺密碼的研究中，降低像素擴展與提高對比是兩個重要的研究主題 ...

Solution‐Processed Thin‐Film Transistors With Tunable Temporal Dynamics for Neuromorphic Computing
Advanced Functional Materials, EarlyView.Solution‐processed CNT and CNT/P3HT ion‐gated transistors exhibit materials‐defined synaptic timescales: fast CNT devices for high‐frequency spiking and slow hybrid devices for temporal integration. Embedding these dynamics into coupled reservoir‐computing and spiking neural network simulations reveals that a Hybrid‐Reservoir / CNT‐SNN architecture ...

Advanced Functional Materials, EarlyView.We introduce a capillary‐filtering‐based particle‐filling (CFPF) process that simultaneously forms vertical thermal pathways and electrical vias within µ‐pores. In situ microfluidic analysis reveals that capillary‐driven velocity gradients generate vorticity that governs µ‐platelet rotation and vertical alignment.
