Stress‐to‐Light Conversion in an Earth‐Abundant Oxide Semiconductor

Advanced Science, EarlyView.
Stress‐to‐light conversion in solids represents a unique photonic functionality, yet it has never been realized in a chemically simple and sustainable material. Here, we show that sustainable semiconductor ZnO exhibits strong near‐infrared (NIR) luminescence under elastic stress when defect‐engineered to stabilize the p‐type state.

Brown Adipocyte Sheets Alleviate Myocardial Ischemia–Reperfusion Injury Through NRG4–ErbB4–Dependent Ferroptosis Inhibition

Advanced Science, EarlyView.
Brown adipocyte sheets are engineered to protect the heart against myocardial ischemia–reperfusion injury by restraining ferroptosis. Upon transplantation onto the cardiac surface, they improve cardiac function, limit infarction and fibrosis, and enhance angiogenesis.

Study Curing Kinetic and Properties of Liquid Crystalline Epoxy Resins

, 2007
本文的研究著重於環氧樹脂與交聯劑的反應動力學與各項性質的探討，其中環氧樹脂採用的是自行合成的液晶型環氧樹(BP, AM)脂與市售的非液晶型環氧樹脂(TMBP, DGEBA)，交聯劑選用的是分子結構較剛硬的DDS，與分子結構較柔軟的DDE。 經由動力學的研究，我們可發現DDE的活化能較低，反應速率較快，但產品的機械性質較差，然而DDS活化能雖高，但由於DDS的分子結構較剛硬，因此其機械性質較佳，適合用於航空材料。 我們利用自催化模型來描述Epoxy/amine的反應過程 ...

Fluorescence Tuning of Carbon Dots from Red to Blue via UV‐Induced Photochemical Etching

Advanced Science, EarlyView.
A UV‐driven photochemical process enables continuous color evolution of carbon dots from red to blue using a single irradiation parameter. Progressive photoetching restructures graphitic domains and surface states, allowing full visible‐spectrum emission control.

Nano Carbon‐mesh with Excellent Bonding Performance via Hydro‐cage De‐shielding Strategy

Advanced Science, EarlyView.
A hydro‐cage de‐shielding strategy transforms cellulose‐based films into a dragonfly‐wing‐like nano carbon‐mesh (NCM) adhesive through instantaneous carbonization‐polymerization. The resulting NCM‐plywood achieves exceptional wet shear strength (1.24 MPa at 63°C), exceeding Class II plywood standards, and retains 0.73 MPa after boiling‐water cycles ...
