Beyond Nanoporosity: A CO2‐Conditioned Glassy Matrix Contributes to the Brittle‐to‐Ductile Transition of Nanocellular Polyetherimide
19/08/2026 - The mechanical performance of nanocellular polyetherimide cannot be explained by nanoporosity alone. It is shown that CO2 saturation and desorption leave a distinct mechanical signature in the glassy...
U-shaped fiber-optic biosensor with gold nanoparticle-assisted signal amplification for allergy-related biomarker detection
- Achieving high analytical sensitivity in fiber-optic biosensors frequently involves a trade-off between signal intensity and structural integrity, particularly when relying on cladding-removal...
Evolution Mechanism of Microstructure and Electrical Conductivity of Laser Directed Energy Deposition (TC4 + TiC)/CuCrZr Under Electroshock Treatment
05/08/2026 - This study presents a synergistic LDED process for a high‐conductivity TMC coating on CuCrZr alloy. Cold‐sprayed Ti pretreatment ensures strong interfacial bonding. Subsequent electropulsing...
