Passively Ultra Cooling Patch Enabling High‐Efficiency Power‐Water Cogeneration

open access: yesAdvanced Materials, EarlyView.
Photovoltaics are the most viable solar energy technology. This work introduces an ultra‐cooling patch (UCP) for passive thermal management of PV, achieving a 28% increase in power density and a water production rate of 2.2 L day−1. The enhancement results from the aligned channels and configurable heat transfer pathways of the UCP, which significantly

Autonomous Implants

open access: yesAdvanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.
