Non‐Covalent Fluorine–Silica Anchoring of a Molecular Platinum(II) bis(NHC) Catalyst: Structure, Interface Control, and Hydrosilylation Activity

open access: yesChemistry – A European Journal, EarlyView.
A Pt(II) bis(NHC) complex is immobilized on mesoporous silica through directional F–Si interactions encoded in the ligand framework. Quantitative 19F{29Si} REDOR experiments and molecular dynamics simulations establish Å‐scale catalyst–support contacts and define the interfacial organization.

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

Governing Agriculture or Farmers? Problem Representations of Biodiversity and Farm Loss in Swedens Strategy for the Common Agricultural Policy

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT European Union (EU) strategies for food supply address challenges of increasing, or at least maintaining, today's level of agricultural food production. At the same time, European farmland biodiversity continues to deteriorate despite considerable investments in measures to promote environmentally friendly farming practices.

Synthesis of α‐C‐Glycoside Conjugates Promoted by 4CzIPN‐Based Porous Organic Polymers Through Giese‐Like Reaction of Glycosyl Bromides in Batch and Continuous Flow

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Visible light and a 4CzIPN‐based porous organic polymer (4CzIPN‐POP) enable Giese‐like coupling of glycosyl bromides with electron‐poor alkenes to access α‐C‐glycoside conjugates. The study shows how heterogeneous thermally activated delayed fluorescence photocatalysis can be combined with continuous flow to overcome light penetration limits and ...

Thirteen years of environmental surveillance of ESKAPE organisms and Escherichia coli in an equine hospital: Informing infection control

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Bacteria from the ESKAPE group (i.e., Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species) and Escherichia coli are frequently multidrug‐resistant and can be associated with healthcare‐associated infections, an increasing concern for veterinary ...

The research progress in polyethylene oxide polymer electrolytes

open access: yesFlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...

Establishing a transdiagnostic dimension of early childhood depressive symptoms using the Preschool Feelings Checklist‐Scale

open access: yesJCPP Advances, EarlyView.
Abstract Background Young child depressive symptoms are associated with various concurrent and future psychiatric problems, indicating early transdiagnostic risk for psychopathology. We now need studies that identify and test the robustness, reliability, and validity of early emerging depressive symptom dimensions, examining them relative to wide ...
