Selective Benzene Capture by Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) hold significant potential for capturing benzene from air emissions and hydrocarbon mixtures in liquid phases. This capability stems from their precisely engineered structures, versatile chemistries, and diverse binding interactions.

Coherent control of covalent bonding by probe electromagnetic field and structured light pulses

Scientific Reports
Covalent and photonic interactions between atoms in lattice are controlled by probe absorption and dispersion spectrums. Similarly, information of covalent interaction among atoms within a crystal is extracted by absorption and dispersion spectrums in ...

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

Advanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Unraveling the molecular recognition mechanism of voriconazole and functional monomers in molecularly imprinted polymer design

South African Journal of Chemical Engineering
Molecularly imprinted polymers (MIP) offer highly selective recognition toward target analytes, yet their performance critically depends on the strength and nature of template–monomer interactions in the pre-polymerization stage.

COVALENCY EFFECTS IN MAGNETIC INTERACTIONS

Le Journal de Physique Colloques, 1976
Magnetic interactions, categorised into ligand based, metal based and neutron diffraction, are reviewed with regard to the information they give on covalency. The ligand hyperfine interaction, the metal hyperfine field measured by the Mössbauer effect and neutron diffraction measurements are mentioned in some detail, with particular emphasis on the ...

The n → π* interaction: a rapidly emerging non-covalent interaction

Physical Chemistry Chemical Physics, 2015
This perspective describes the current status of a recently discovered non-covalent interaction named as the n → π* interaction, which is very weak and counterintuitive in nature.

Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

Advanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

Advanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...
