High Center‐of‐Mass, Multi‐Legged Soft Robots Powered by Geometrically Encoded Liquid Crystal Elastomer Arc Appendages

open access: yesAdvanced Materials, EarlyView.
Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Enhanced Photocatalytic H2O2 Production on Terpyridine‐Based Acrylonitrile‐Linked Covalent Organic Frameworks with Asymmetric Localized Electron Distribution

open access: yesAdvanced Materials, EarlyView.
Asymmetric localized electron distribution has been optimized in covalent organic frameworks to enhance *O2 adsorption and facilitate charge transfer, boosting photocatalytic two‐electron transfer oxygen reduction toward H2O2 production from water and air.

Engineering Layered Magnetic Hydrogels for Cell Placement via Shear and Magnetic Field‐Induced Assembly

open access: yesAdvanced Materials, EarlyView.
Magnetic particles are organized into layered architectures by combining shear flow and magnetic fields, with the resulting structures governed by appropriate Mason numbers. The programmed assemblies provide spatial guidance for cell placement, linking field‐controlled self‐assembly, flow‐induced structuring and biological organization.

CS observations of L1551 - No rotating disk

open access: yesThe Astrophysical Journal, 1987
High angular resolution observations were made of the CS emission from the core of the L1551 molecular cloud, using a technique of heavy oversampling and maximum entropy reconstruction. The observations are consistent with the data published by Kaifu et al.

Field‐Programmable Mobile Magneto‐Photonic Metaparticles for Active Light Manipulation and Steering

open access: yesAdvanced Materials, EarlyView.
We report magneto‐photonic metaparticles that integrate magnetic actuation with nanoimprinted metagratings, enabling mobile and programmable beam steering in aqueous environments. This platform achieves real time, directional light control beyond static or line‐of‐sight systems, while remaining compatible with scalable fabrication, providing a ...

Does Anything Happen on a Rotating Disk?

open access: yes, 2004
The paper discusses the issue of time and length measurements on a rotating disk. Considering operational procedures it is shown that the only relevant phenomena related to the rotation of the disk are the ones affecting clocks. Direct measurements of length do not give results in contrast with the ones obtainable for a non-rotating disk.

Exact Relativistic Magnetized Haloes around Rotating Disks

open access: yesAdvances in Mathematical Physics, 2015
The study of the dynamics of magnetic fields in galaxies is one of important problems in formation and evolution of galaxies. In this paper, we present the exact relativistic treatment of a rotating disk surrounded by a magnetized material halo.
