Cretaceous-Tertiary boundary layer at Stevns Klint (Denmark): copper and copper(II) porphyrins

Journal of the Serbian Chemical Society, 1999
High concentrations (up to 4000 ppm) of copper(II) porphyrins have been detected in the kerogen of the Cretaceous/Tertiary (KT) boundary informal type sediment, the Fish Clay, at Stevns Klint, Denmark. These pigments have also been found in the Danish KT

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

BMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

Bismuth‐Based Semiconductors in Photocatalytic CO2 Reduction: Catalysts, Progress, and Future Perspectives

Carbon and Hydrogen, EarlyView.
This review systematically summarizes research progress on bismuth‐based semiconductor photocatalytic materials in the field of CO2 reduction. It focuses on elucidating the mechanisms by which four modification strategies—including heteroatom doping, oxygen vacancy engineering, microstructural control, and heterostructure fabrication—regulate band ...

Unveiling the Potential of Metal and Non‐Metal Modified Porous Carbon for the Electrochemical Reduction of CO2

Carbon Energy, EarlyView.
Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.

Interplay of Bridge Topology and Conformation in Phenylene‐Bridged Trityl Diradicals

Chemistry – A European Journal, EarlyView.
We present a meta‐phenylene‐bridged trityl diradical that exhibits an unexpectedly weak antiferromagnetic exchange coupling J with a strong environment‐dependent magnitude. Combined VSM, EPR, DFT, and MD studies reveal that structural flexibility modulates σ‐, π‐, and through‐space exchange contributions, highlighting the crucial role of geometry in ...
