Biointegrated Multilayer Stretchable OLED Platform With Strain‐Decoupled Architecture for Durable Phototherapeutic Applications

Advanced Science, EarlyView.
A multilayer stretchable organic light‐emitting diode (SOLED) patch enables conformal, high‐fill‐factor phototherapeutic illumination through vertically decoupled electrodes and robust encapsulation. The textile‐based SOLED platform delivers stable skin‐contact red light for wearable phototherapy and 5‐aminolevulinic acid (ALA)‐mediated photodynamic ...

Strain‐Adaptive Dielectric Metamaterials via Bioinspired “Ligament‐Bone” Architecture for Ultrahigh‐Energy Capacitive Storage

Advanced Science, EarlyView.
A bioinspired strain‐adaptive ligament‐bone architecture achieves record‐high energy density of 26.1 J cm−3 and 90% efficiency at 600 MV m−1, coupled with a Young's modulus of 2.13 GPa. ABSTRACT Polymer dielectrics for capacitive energy storage face fundamental trade‐offs between breakdown strength, energy density, efficiency, and mechanical robustness.

Enhanced Mechanical Properties Via Boron‐Induced Multi‐Mechanism Strengthening in (NbTaTi1.5V)100‐xBx Refractory High Entropy Alloys

Advanced Science, EarlyView.
A trace amount of boron is introduced into NbTaTi1.5V RHEA, forming a finegrained BCC+TiO+TiB microstructure. The TiB phase generates numerous dislocations, strengthening the alloy. The alloy exhibits 3610 MPa compressive fracture strength and 1060 HV microhardness, while retaining 14.8% fracture strain.

The cavity damage evolution of heat-resistant steel weldment under different creep conditions

四川大学学报. 自然科学版
Creep testing was conducted on two types of welded joints made of martensitic heat-resistant steel (F92/Co3W2 and Co3W2/Co3W2) at temperatures ranging from 873 K to 948 K and stress levels ranging from 105 MPa to 250 MPa.

Programmable Multi‐Axially Aligned Aerogels via Sequential Freeze‐Casting for Tailored Anisotropy and Tunable Mechanics

Advanced Science, EarlyView.
Conventional single‐gradient freeze‐casting typically produces unidirectional porous architectures with limited transverse connectivity. The Sequential Hybridization by Infiltration and Freeze‐casting Technique (SHIFT) addresses this constraint by integrating secondary aligned structures within a preformed primary scaffold.
