Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion
Advanced Science, EarlyView.In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials
Advanced Science, EarlyView.ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Fraud or Poverty? Medieval Wedding Rings of Legnica Jews
Acta Universitatis Lodziensis: Folia ArchaeologicaWedding rings have been known since antiquity. In the Roman Empire, they took the form of bands adorned with a motif of two clasped hands. In Jewish culture, the engagement (kiddushin, erusin) – during which a ring was given – and the wedding (nissu’in)

Pin-On-Disc Characterization of Brass/Ferritic and Pearlitic Ductile Iron Rubbing Pair
High Temperature Materials and Processes, 2011 Wear behaviour of special brass produced through two different methods (centrifugal and sand casting) was investigated. The wear tests were carried out at sliding velocities of 0.2 ms–1, 0.3 ms–1, 0.4 ms–1 and 0.5 ms–1 and under 10 N, 20 N, and 40 N ...

Advanced Science, EarlyView.A thermally programmable two‐port non‐Hermitian acoustic metastructure is presented, where temperature acts as a non‐geometric tuning variable. Thermal modulation reconfigures impedance matching and loss‐leakage coupling, enabling exceptional‐point driven, broadband, and direction‐dependent sound absorption without requiring geometric reconfiguration ...

Advanced Energy Materials, EarlyView.This study investigates the feasibility of scaling up Prussian White (PW)‐based cathode manufacturing at a pilot scale. Through careful PW dehydration combined with optimized aqueous processing, we report the stepwise development of industrially relevant 1 Ah pouch cells and evaluate their performance under various conditions.
