Exceptional Antimodes in Multi‐Drive Cavity Magnonics

Advanced Electronic Materials, EarlyView.
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

Spin‐Polarized Interfaces Redirect CO2 Reduction From CO to Formate

Angewandte Chemie, EarlyView.
The chiral electrocatalyst exploits the CISS effect to establish a spin‐polarized interface that selectively promotes formate production during CO2 reduction while effectively suppressing the competing hydrogen evolution. ABSTRACT Achieving high product selectivity in electrocatalytic carbon dioxide reduction (CO2RR) remains a critical challenge due to

Theology and natural philosophy in late seventeenth and early eighteenth-century Britain [PDF]

, 1996
A number of historians of science have claimed that the early Boyle Sermons provided a platform for the promotion of a moderate-Anglican social and political ideology underpinned by Newtonian natural philosophy.

Electric Field‐Induced Hole‐ and Electron‐Type Flat Bands in Twisted Double Bilayer Graphene

Advanced Electronic Materials, EarlyView.
The electronic structure of twisted double bilayer graphene is visualized using angle‐resolved photoemission spectroscopy with micrometer spatial resolution at twists of 3.1∘$^\circ$ and 6.0∘$^\circ$ as a function of gate voltage. Tunable hybridization effects and flat band formation occurs between valence and conduction band states due to a finite ...

Solvent Hydrogen Bonding Determines Adsorption Geometry of Trimesic Acid on Cu

Angewandte Chemie, EarlyView.
Water reorients adsorbate molecules. Combined tip‐enhanced Raman spectroscopy, density functional theory and molecular dynamics simulations reveal the adsorption geometry of trimesic acid on Cu. Subtle adsorbate–substrate–solvent energy differences due to hydrogen bonding dictate molecular orientation at solid/liquid and solid/gas interfaces, providing

Selective Tuning of Perpendicular Magnetic Anisotropy and Dzyaloshinskii–Moriya Interaction in Heterostructures Compatible with Magnetic Tunnel Junctions

Advanced Electronic Materials, EarlyView.
ABSTRACT Chirally coupled magnetic tunnel junctions (MTJs) have been proposed as a route toward compact spin logic architectures. Micromagnetic simulations indeed show that chiral coupling between adjacent MTJs with perpendicular magnetic anisotropy (PMA) can be achieved through an in‐plane (IP) interconnection mediated by the Dzyaloshinskii–Moriya ...

Tailoring Photochromism Beyond Human Eye Visibility: On/Off Switchable NIR Absorption in an Aluminosilicate

Angewandte Chemie, EarlyView.
A new photochromic material was developed. Its on/off‐switchable absorption band is situated completely outside the human eye's visibility, in the near‐infrared (NIR) region, a feature never reported before. The photochromism mechanism in this aluminosilicate is elucidated by combining experimental as well as computational results, and the material's ...

Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization

Advanced Energy Materials, EarlyView.
Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...

Large Language Model‐Based Chatbots in Higher Education

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The use of large language models (LLMs) in higher education can facilitate personalized learning experiences, advance asynchronized learning, and support instructors, students, and researchers across diverse fields. The development of regulations and guidelines that address ethical and legal issues is essential to ensure safe and responsible adaptation
