A Bistable Assistive Device for Wireless Control of a Dysfunctional Bladder Under Minimal Stress

open access: yesAdvanced Materials Technologies, EarlyView.
This paper presents a wireless system designed to restore bladder function in patients with an underactive bladder (UAB). The system features a multilayered structure, combining a pre‐shaped restoration layer with a spring‐based actuator. The system delivers 95–100% voiding efficiency within a 10‐s activation while ensuring minimal stress on the ...

Long‐Term Study of Optical Nanoparticles Doped With Yb3+/Er3+ and Transition Metal Ions and their Real Application for Imaging and Temperature Sensing on Triticum Aestivum L.

open access: yesAdvanced Optical Materials, EarlyView.
This work shows a study on SrF2:Yb3+, Er3+ water colloid, additionally doped with transition metals (Sc3+ or Zn2+) to enhance observed emission, tested during 22 weeks of storage in ambient conditions. Due to high stability, excellent optical properties achieved under 975 nm excitation, and negligible phytotoxicity, the nanoparticles are applied for ...

Bleeding‐Mimetic Damage‐Detecting and Self‐Healing Modular Skin for Inflatable Structures

open access: yesAdvanced Robotics Research, EarlyView.
A damage‐detecting and self‐healing system inspired by the human bleeding mechanism is developed for inflatable structures, using a liquid conductive elastomeric material enclosed in a small pouch. This material, composed of uncured elastomer, its curing agent, conductive particles, and a dispersant, solidifies only after being exposed to air and ...

The Global Warming Potential of Geoengineering via Radiative Cooling

open access: yesAdvanced Sustainable Systems, EarlyView.
The cooling power of engineered radiative cooling materials is determined and compared to conventional construction and roofing materials and Earth's natural surfaces. Results show if 1% of Earth's surface are to be covered with state‐of‐the‐art radiative cooling materials the terrestrial radiative forcing would decrease by 1.61 W·m−2 (from 0.6 to −1 ...
