Extending Field Limits in Nanoscale Magnetic Imaging With Metamaterial‐Inspired Magnetic Flux Concentrators

Small, EarlyView.
Micrometer‐sized flower‐shaped metamaterial magnetic flux concentrators are fabricated directly around nano and micromagnetic samples, enabling local field enhancement. Integrated into magnetic sensitive photoemission electron microscopy, they extend the available magnetic field range by up to a factor of five.

Synergistic Sr2+ Doping and MXene Engineering of Layered δ‐MnO2 Toward High‐Performance Aqueous Zinc‐Ion Batteries

Small, EarlyView.
Sr‐doped δ‐MnO2/Nb2C composites are engineered for aqueous zinc‐ion batteries, utilizing Sr2+ doping and conductive Nb2C to enhance structural stability and ion transport. The optimized cathode delivers a 407.3 mAh g−1 capacity and excellent cycling, driven by a reversible Zn2+/H+ co‐insertion mechanism, making it suitable for flexible electronics ...

Molecular‐Level Engineered Approach Induces Built‐in Electric Field Modulation in G‐C3N4/CoMoS2 Heterojunction for Enhanced Hydrogen Generation via Urea Oxidation

Small, EarlyView.
Urea‐assisted electrolysis is demonstrated as an energy‐efficient route for hydrogen production by replacing the sluggish oxygen evolution reaction with kinetically favorable urea oxidation. An intrinsic electric‐field‐driven g‐C3N4/CoMoS2 heterojunction induces directional charge redistribution, promotes selective urea activation, and accelerates C─N ...

Linking Pulse‐Duration‐Controlled Laser Nanostructuring to Oxygen Evolution Kinetics in Fe‐enriched NiOx Electrodes

Small, EarlyView.
Pulse‐duration‐controlled ultra‐short laser processing is shown to directly create binder‐free Fe‐enriched NiOx electrodes with tunable porosity, active‐site density, and oxygen‐evolution kinetics. Shorter pulses generate defect‐rich nanostructures that accelerate charge transfer, promote highly active NiFeOOH formation, and deliver durable alkaline ...

Mammalian Osteoderm Ultrastructure in the Armored Acomys Spiny Mouse Tail

Small, EarlyView.
The ultrastructure of armored platelets – termed osteoderms – in the tail skin of Acomys cahirinus spiny mice is characterized using 2D and 3D microscopy methods. The imbricated structure is composed of calcium phosphate biomineral and has select structural elements that are bone‐like and tooth‐like in nature.

Easily Accessible and Up‐Scalable Aliphatic Bis‐Formamides with Afterglow Luminescence: Photoluminescence Properties and Applications

Small, EarlyView.
A bis formamide molecule was found to feature afterglow properties, in both crystalline powder state and in polyvinyl alcohol films. This was attributed to the intermolecular packing that allows H‐trapped emitting state and/or clustering‐triggered emission, which was intensified upon insertion of tetramethylbenzidine as a doping agent.
