Mitochondrial Transplantation via Magnetically Responsive Artificial Cells Promotes Intracerebral Hemorrhage Recovery by Supporting Microglia Immunological Homeostasis

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
A type of magnetically responsive artificial cells (ACs) has been developed, demonstrating the loading of mitochondria and self‐enclosure processes to ensure the protection of mitochondrial transport via the bloodstream. The treatment with ACs effectively transplanted mitochondria around the lesion, thereby improving neurological recovery by supporting

Dual‐Scale Hydration‐Induced Electrical and Mechanical Torsional Energy Harvesting in Heterophilically Designed CNT Yarns

Advanced Materials, EarlyView.
Despite the abundance and vast energy potential of water, its efficient utilization is hindered by single‐mode energy conversion. Herein, heterophilic CNT yarns that allow for simultaneous energy harvesting by means of dual‐scale hydration—electrical energy harvesting through proton gradients and mechanical torsional harvesting through microchannel ...
