Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Impact of Anode to Cathode Crossover in Lithium‐metal Batteries With High‐Nickel Cathodes
Anode‐to‐cathode chemical crossover is identified as a critical degradation mechanism in lithium‐metal batteries. Full‐cell experiments with high‐Ni layered oxide cathodes and localized high‐concentration electrolytes reveal accelerated cathode impedance growth and CEI thickening driven by lithium‐metal anodes. The findings underscore the importance of

The novel gradient‐modified LRMO has been synthesized via a one‐step mechano‐fusion process, with simultaneous S and Zr co‐doping in the near‐surface region and an amorphous coating. The synergistic co‐functionalization stabilizes the oxygen framework, enhances charge transport, and suppresses oxygen dimerization under high potential, which enable ...

Opportunities for Multiscale Pattern Modulation with Temporally Arrested Breath Figures
This works presents the temporally arrested breath figure methodology and its opportunities for pattern modulation. Through thermodynamic and photochemical phase change handles, this method uses drop‐wise condensation as a dynamic template for fast, accessible and scalable micropatterning.

Conductive silk‐polypyrrole scaffolds couple redox stability with cell‐affinitive peptides present innately in an endogenous silk fibroin, enabling optimized electrical stimulation to drive neurite outgrowth. Findings establish electrochemical‐biological link for biomaterial design rules for smart nerve guidance conduits that can provide low voltage ...
