Boron Monofluoride Complexes Bearing π‐Expanded Coumarin Subunits: Facile Synthesis, Crystal Structure, and Solid‐State Enhanced Emission

Chemistry – A European Journal, EarlyView.
We here report the design, facile synthesis, experimental, and theoretical characterization of a novel class of monofluoroborate compounds featuring π‐expanded coumarin subunits displaying solid‐state enhanced Emission. The origin of this phenomenon is disclosed by combined theoretical and spectroscopic investigations.

Amino Acid Modified Polymer Mesh for Removal of the Heavy Metal Ions Pb2+, Hg2+, Cu2+, and Ni2+ From Aqueous Solutions

Chemie Ingenieur Technik, EarlyView.
Adsorbents for cations of copper, lead, mercury, and nickel are obtained via grafting polymer mesh with an acrylic acid copolymer and subsequent functionalization with an amino acid. A distinct influence of the type of amino acid on the adsorption occurs.

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Light‐Modulated Exchange Bias in Multiferroic Heterostructures

Electron, EarlyView.
In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.

Development and Validation of a Seismic Design Method for Anchored Retaining Walls

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Retaining walls with multiple anchor levels are widely used as permanent excavation support systems for the construction of linear infrastructures. Yet, their seismic behaviour remains largely unexplored, and current design approaches rely on conventional procedures that do not adequately reflect the actual dynamic response of these systems ...

Flexible lithium‐ion batteries: Materials design, interfacial regulation, and strain‐adaptive device architectures

FlexMat, EarlyView.
This review highlights recent advances in flexible lithium‐ion batteries for wearable and deformable electronics. It systematically examines deformable electrodes, mechanically compliant gel and solid‐state electrolytes, and strain‐adaptive cell architectures, alongside an analysis of mechano‐electrochemical coupling under dynamic deformation.
