Covalent and non-covalent interactions between catechin and anchovy derived pentapeptides PAYCS: the differential neuroprotective effects on APP/PS1 amnesia mice

open access: yesFood Science and Human Wellness
Interactions between proteins/peptides and polyphenols have been widely investigated to improve their properties and functions. Previous studies have shown that covalent and non-covalent products exhibit different structural and bioactivity ...

Upcycling Keratin‐Based Textile Waste Into High‐Performance Hybrid Fibers Via Tuning the Interfacial Interactions

open access: yesAdvanced Functional Materials, EarlyView.
Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.

Deciphering the Photopolymerization‐Induced Nanostructures and Interface Formation for Submicrometer Additive Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
This work reveals the UV‐curing‐induced monomer‐rich domain, oligomer‐rich domain, and entangled oligomer domain. The cured submicron films in stressed state induce interlayer nano‐wrinkle structures during the deposition of the second layer. Stress‐free cured films in relaxed state form non‐diffusive, diffusive and semi‐diffusive interlayer ...

Hydrogen bonding template enables remote meta-C–H alkenylation of nitroarenes with electron-deficient alkenes

open access: yesNature Communications
Regioselective distal C−H functionalization of nitroarenes by overriding proximal C−H activation has remained an unsolved challenge. Herein, we present a palladium-catalyzed meta-C−H alkenylation of nitroarene substrate, achieved through leveraging the ...

COVALENCY EFFECTS IN MAGNETIC INTERACTIONS

open access: yesLe 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 ...

Gas-phase covalent and non-covalent ion/ion chemistry of biological macromolecules [PDF]

open access: yes, 2013
Gas-phase ion/ion chemistry involves the interaction of oppositely charged ions inside of the mass spectrometer. During this gas-phase chemistry, particle transfer (i.e., proton and electron) or synthesis can occur at rapid reaction rates.

Genetically Programmed Shape‐Morphing of Engineered Living Materials

open access: yesAdvanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

On the Covalent Character of Rare Gas Bonding Interactions: A New Kind of Weak Interaction

open access: yes, 2016
At the averaged quadratic coupled-cluster (AQCC) level, a number of selected rare gas (Rg) containing systems have been studied using the quantum theory of atoms in molecules (QTAIM), natural bond orbital (NBO), and several other analysis methods ...
