Exosomes derived from adipose mesenchymal stem cells promote corneal injury repair and inhibit the formation of scars by anti-apoptosis.

In the corneal wound healing process, epithelial cell re-epithelialization and migration are the critical first steps following an injury. As the disease progresses, orderly regeneration of corneal stromal collagen and mild corneal stromal fibrosis are vital for corneal function reconstruction. Exosomes derived from adipose-derived mesenchymal stem cells (ADSCs-Exos) have emerged as a promising therapy due to their anti-oxidant, anti-apoptosis, and tissue repair properties.

Overcoming the Unfavorable Effects of "Boltzmann Tyranny:" Ultra-Low Subthreshold Swing in Organic Phototransistors via One-Transistor-One-Memristor Architecture.

Organic phototransistors (OPTs), as photosensitive organic field-effect transistors (OFETs), have gained significant attention due to their pivotal roles in imaging, optical communication, and night vision. However, their performance is fundamentally limited by the Boltzmann distribution of charge carriers, which constrains the average subthreshold swing (SS) to a minimum of 60 mV/decade at room temperature. In this study, an innovative one-transistor-one-memristor (1T1R) architecture is proposed to overcome the Boltzmann limit in conventional OFETs.
