A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

open access: yesAdvanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Iridium‐Catalyzed Ionic Hydrogenation of Multi‐Aza Heterocycles

open access: yesAngewandte Chemie, EarlyView.
Saturated nitrogen‐containing heterocycles are ubiquitous in bioactive molecules and are thus attractive synthetic targets. A readily accessible cyclometalated iridium(III) complex reduces 14 different aromatic aza heterocycles to (partially)saturated multi aza‐heterocycles enlarging accessible chemical space while displaying high tolerance toward ...

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications

open access: yesAdvanced Robotics Research, EarlyView.
Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

Dyotropic Rearrangement of Hypervalent Iodine Species: Migrative Heterofunctionalization of Quaternary Carbons

open access: yesAngewandte Chemie, EarlyView.
1,2‐Aryl migration involving in situ‐generated alkyl iodine(III) species proceeds through a previously unrecognized 1,2‐C/I(III) dyotropic rearrangement. Migratory aryl fluorination, acetoxylation, and alkoxylation of 2‐alkyl‐2‐aryl‐3‐iodopropanoates provide α‐heterofunctionalized products, accompanied by aryl migration from the α‐ to the β‐position ...

Bending‐Stable Pressure Sensor Based on Natural Wood Nanofibers for Ultra‐Low Detection Limit

open access: yesAdvanced Science, EarlyView.
A wood nanofiber‐based flexible pressure sensor with intrinsic bending‐stable performance is developed through a porous electrospun architecture and interdigital electrode design. The device exhibits an ultra‐low detection limit and stable operation under deformation for physiological monitoring and spatial sensing, providing a sustainable strategy for

Cycling Performance of Sodium‐Metal Chloride Battery Cells and Modules Based on Iron and Zinc

open access: yesAdvanced Energy Materials, EarlyView.
High‐utilization sodium–metal chloride cells with a mixed‐metal Fe, Zn, NaCl cathode enable efficient high‐temperature cycling (300°C) while reducing cost and environmental impact. Near‐theoretical capacity and high efficiency are achieved in single cells.

Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis

open access: yesHepatology, EarlyView., 2022
Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis. Abstract Background and Aims Nucleotide‐binding oligomerization domain‐like receptor‐family pyrin domain‐containing 3 (NLRP3) inflammasome activation has been shown to result in liver fibrosis.
