2D PtSe Enabled Wireless Wearable Gas Monitoring Circuits with Distinctive Strain-Enhanced Performance.

The application of 2D materials-based flexible electronics in wearable scenarios is limited due to performance degradation under strain fields. In contrast to its negative role in existing transistors or sensors, herein, we discover a positive effect of strain to the ammonia detection in 2D PtSe. Linear modulation of sensitivity is achieved in flexible 2D PtSe sensors via a customized probe station with an in situ strain loading apparatus.

Mitochondrial quality control in abdominal aortic aneurysm: From molecular mechanisms to therapeutic strategies.

Mitochondria are the energy supply sites of cells and are crucial for eukaryotic life. Mitochondrial dysfunction is involved in the pathogenesis of abdominal aortic aneurysm (AAA). Multiple mitochondrial quality control (MQC) mechanisms, including mitochondrial DNA repair, biogenesis, antioxidant defense, dynamics, and autophagy, play vital roles in maintaining mitochondrial homeostasis under physiological and pathological conditions.
