Astrocytic Mitochondria Transplantation Rescues Neuron Loss and Dendritic Injuries in Acute Cerebral Ischemic Stroke Mouse Model by Flexibly Regulating Mitochondria Dynamics

Annals of Neurology, EarlyView.
Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.

Mixed Ion‐Electron Thermoelectric Generators With Ionogels Blended With MXene Continuously Harvesting Heat Under Both Steady and Fluctuated Temperature Gradients

Carbon Energy, EarlyView.
A mixed ion‐electron thermoelectric generator (MTEG) based on MXene ionogels converts both steady and fluctuating temperature gradients into continuous electricity. The hybrid conduction arises from electron tunneling through MXene networks and ionic diffusion driven by the Soret effect, enabling stable voltage output and high thermopower for efficient
