Evaluation of Radiation Response in CoCrFeNiNb0.65 Eutectic High-Entropy Alloys

, 2023
A CoCrFeNiNb0.65 eutectic high-entropy alloys (EHEAs) prepared by arc melting were irradiated with a 100 keV He+ ion beam. Swelling, helium bubbles and mechanical response induced by irradiation were evaluated. When the ion fluence reached 1.0×1018 ions/cm2, the irradiation-induced swelling occurred on the sample surface, and as the ion fluence ...

Thermochemical Micro‐Explosion for Prompt Thrombolysis via Proximal Injection of Liquid Alkali Metal

Advanced Science, EarlyView.
We report a micro‐explosive thermochemical thrombolysis (METCT) therapy via injectable liquid alkali metal encapsulated in dimethyl silicone (LAM@oil). METCT enables prompt and safe vascular recanalization within 90 s. Critically, the LAM@oil system demonstrates significantly higher thrombolytic efficacy compared to clinically available thrombolytic ...
