Shape Morphing Programmable Systems for Enhanced Control in Low‐Velocity Flow Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
A soft, Lorentz‐force‐driven programmable surface enables rapid, reversible shape morphing for active flow control. Integrating experimental, numerical, and modeling approaches, the system demonstrates effective modulation of near‐wall flow and momentum at low velocities, offering pathways for bio‐inspired aerodynamics and natural locomotion emulation.

Haptic Perception via the Dynamics of a Flexible Body Inspired by an Ostrich's Neck

open access: yesAdvanced Intelligent Systems, EarlyView.
Inspired by avian anatomy, this study uses a flexible robotic neck to investigate haptic perception driven by musculoskeletal dynamics. By applying physical reservoir computing, the robot encodes external force interactions into its body dynamics, allowing effective object classification.

Photopolymerization‐Induced Phase Separation in (Meth)Acrylate‐Based Photopolymers From a Characterization Point of View

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT This work investigates the development of photopolymerization‐induced phase separation (PhIPS) in methacrylate‐based photopolymers. Bisphenol A ethoxylated dimethacrylate (BisEMA) was copolymerized with urethane‐based diacrylate diluted in isobornyl acrylate (UI) under UV irradiation, using diphenyl‐(2,4,6‐trimethylbenzoyl) phosphine oxide ...

Fouling in Emulsion Polymerization: Fundamentals and Methods of Investigation

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT The current understanding of fouling in emulsion polymerization is summarized from an engineering perspective and from a physical‐chemistry perspective. Emulsion polymerization in semibatch mode offers better control over the number of particles and side reactions than batch mode. Both reaction fouling and particulate fouling are observed, the

Ultrafast Demagnetization Through Femtosecond Generation of Non‐Thermal Magnons

open access: yesAdvanced Physics Research, EarlyView.
A fully ab initio parametrized model is developed to describe out‐of‐equilibrium magnon dynamics in ferromagnetic metals. Applying this model to ultrafast laser‐induced demagnetization, it is revealed that the generation of non‐thermal magnons provides a sizable demagnetization within 200 fs in excellent comparison with experiments, which establishes ...

Mechanical Spin Waves in a Nonlocal Discrete Magnetoelastic Lattice with Negative Group Velocity

open access: yesAdvanced Physics Research, EarlyView.
A discrete magnetoelastic lattice enables mechanical spin waves. The zigzag‐arranged lattice consists of repulsive magnets. The top and bottom rows of the zigzag lattice show opposite spin directions. These spin waves arise due to the coupling between longitudinal and transverse motions.

Enhancing Signal Purity in Josephson Structure Measurements

open access: yesAdvanced Physics Research, EarlyView.
A low‐noise signal measurement system for dilution refrigerators is presented, combining multistage cryogenic filtering and electromagnetic shielding to suppress broad‐spectrum noise. The setup enables sub‐nanoampere switching current measurements in Josephson junctions, surpassing commercial systems.
