Advanced Functional Materials, EarlyView.Oxygen‐doping modulated g‐C3N4 support enables a strong built‐in electric field (BIEF) in FeOCl‐OCN.This enhanced BIEF induces the rearrangement of Fe(II)/Fe(III) in FeOCl, which subtly improves intermediates adsorption and also reduces the energy barrier of *O production, thereby achieving efficient PMS activation with 1O2 and Fe(IV)= O as the primary

(15-crown-5)BiI$_3$ as a Building Block for Halogen Bonded Supramolecular Aggregates [PDF]
arXiv, 2020 We present the synthesis and characterization of (15-crown-5)BiI$_3$ (1) and (15-crown-5)BiI$_3$*0.5TIE (2), a halogen bonded adduct with tetraiodoethylene (TIE), a typical halogen bond donor. Our results show that crown ether complexes of main group metal halides can be employed as halogen bond acceptors for the synthesis of new supramolecular ...

Monomer-induced customisation of UV-cured atelocollagen hydrogel networks [PDF]
, 2018 The covalent functionalisation of type I atelocollagen with either 4-vinylbenzyl or methacrylamide residues is presented as a simple synthetic strategy to achieve customisable, cell-friendly UV-cured hydrogel networks with widespread clinical applicability. Molecular parameters, i.e. the type of monomer, degree of atelocollagen functionalisation and UV

Transient Stiffness Patterning in Hydrogels Driven by Dissipative Mechanochemical Coupling
Advanced Functional Materials, EarlyView.Force‐induced disulfide bond rupture in a polymer‐based hydrogel, coupled with chemical or electrochemical reoxidation, leads to the transient modulation of the hydrogel's stiffness properties. High spatiotemporal control is achieved by this dissipative process, enabling the development of out‐of‐equilibrium stiffness patterns and transient, dose ...

Structure of superoxide reductase bound to ferrocyanide and active site expansion upon X-ray-induced photo-reduction [PDF]
Structure, 2004, 12, pp.1729-40, 2015 Some sulfate-reducing and microaerophilic bacteria rely on the enzyme superoxide reductase (SOR) to eliminate the toxic superoxide anion radical (O2*-). SOR catalyses the one-electron reduction of O2*- to hydrogen peroxide at a nonheme ferrous iron center. The structures of Desulfoarculus baarsii SOR (mutant E47A) alone and in complex with ferrocyanide
