Electrostatic Actuation Induces Competing Adhesion and Vibration Regimes at Fingertip Contact

open access: yesAdvanced Intelligent Systems, EarlyView.
Electric fields modulate fingertip–surface contact to create artificial touch sensations. The mechanisms underlying electrostatic friction, however, remain unclear. Direct imaging and friction measurements under oscillating electric fields showed that adhesion dominates at high frequencies, while vibration contributes substantially at the lower ...

Controlling Exsolution Dynamics in High‐Entropy Oxides for Highly Active and Selective Acetylene Semi‐Hydrogenation

open access: yesAngewandte Chemie, EarlyView.
Li+‐induced lattice distortion, valence variation, and local charge redistribution in a rock salt‐structured high‐entropy oxide enable controlled metal exsolution, altering the Cu–Ni–Co exsolution sequence and delivering a surface Cu0‐enriched catalyst with exceptional activity and ethylene selectivity for acetylene semi‐hydrogenation.

Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Development and Characterization of ZnO‐Filled and Maleic Anhydride‐Compatibilized PP/SEBS Blends for 3D‐Printing Filaments

open access: yesJournal of Applied Polymer Science, EarlyView.
PP/SEBS/MA/ZnO filaments produced by bench‐top single‐screw extrusion show refined morphology, increased crystallinity, improved thermal robustness, and preliminary FFF printability, demonstrating a practical route for functional filament development. ABSTRACT Currently, single‐screw extrusion offers a versatile and accessible route to produce polymer ...

Detecting introgression from phylogenetic invariant site patterns using machine learning

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Detecting historical introgression among populations or species from genomic data is a common goal in evolutionary genetics. Most current methods fall into two major categories: network inference and admixture inference. Network inference (e.g., SNaQ) is computationally challenging and typically requires first reducing large genomic ...

Tuning the Magnetic Phase Transitions in TbMn2‐xTixSi2 (x = 0–0.3)

open access: yesAdvanced Physics Research, EarlyView.
ABSTRACT Magnetocaloric materials receive considerable attention as promising candidates for next‐generation energy‐efficient and environmentally benign solid‐state refrigeration technologies. These materials exhibit the magnetocaloric effect (MCE), whereby heat is absorbed or released upon the application or removal of a magnetic field. In this study,

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review

open access: yesAdvanced Physics Research, EarlyView.
Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.

Moiré Folded Helical States at the Interfaces of Heterostructures

open access: yesAdvanced Physics Research, EarlyView.
This manuscript explores a minimal ladder model of a graphene‐topological‐insulator heterostructure where moiré superlattices modulate Rashba spin‐orbit coupling. The study reveals that SOC lifs spin degeneracy, halves spectral periodicity, and induces “helicity fragmentation” across moiré minibands.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...
