Polyoxometalates as chemically and structurally versatile components in self-assembled materials

Polyoxometalates (POMs) are anionic molecular metal oxides with expansive diversity in terms of their composition, structure, nuclearity and charge. Within this vast collection of compounds are dominant structural motifs (POM...

Chaperones mainly suppress primary nucleation during formation of functional amyloid required for bacterial biofilm formation

Unlike misfolding in neurodegenerative diseases, aggregation of functional amyloids involved in bacterial biofilm, e.g. CsgA (E. coli) and FapC (Pseudomonas), is carefully regulated. However, it is unclear whether functional aggregation...

Sequence-Independent Activation of Photocyloadditions Using Two Colors of Light

We exploit two reactive chromophores to establish sequence-independent photochemical activation, employing ortho-methyl benzaldehyde (oMBA) and N,N-(dimethylamino)pyrene aryl tetrazole (APAT) with N-(2-hydroxy)ethyl maleimide (NHEM), without any additives. Critically, the order of...

Single-atom cobalt-hydroxyl modification of polymeric carbon nitride for highly enhanced photocatalytic water oxidation: ball milling increased single atom loading

Expediting the oxygen evolution reaction (OER) is the key to achieving efficient photocatalytic overall water splitting. Herein, single-atom Co−OH modified polymeric carbon nitride (Co-PCN) was synthesized with single-atom loading increased...

Kinetic Trapping of a Cobalt(II) Metallocage using an Carbazole-Containing Expanded Carbaporphyrinoid Ligand

The meso-unsubstituted expanded porphyrinoid 3, incorporating two carbazole moieties, acts as an effective ligand for Co(II) and permits the isolation and X-ray diffraction-based characterization of a 6:3 metal-to-ligand metallocage complex...

Polariton Ring Currents and Circular Dichroism of Mg-porphyrin in a Chiral Cavity

By placing a Mg-porphyrin molecule in a chiral optical cavity, time reversal symmetry is broken, thus generating polariton ring currents even with linearly polarized light. These currents induce a circular...

Non-metal boron atoms on CuB12 monolayer as efficient catalytic sites for urea production

Electrocatalytic C-N coupling reaction to convert CO2 and N2 into urea under mild conditions has been proposed to be a promising alternative experimentally, but the development of high-stable, low-cost and...

Ultrafast Temporal Evolution of Interatomic Coulombic Decay in NeKr Dimers

We investigate interatomic Coulombic decay in NeKr dimers after neon inner-valence photoionization [Ne+(2s-1)] using a synchrotron light source. We measure with energy resolution the two singly charged ions of the...

Achieving blue-excitable yellow-emitting Ca-LMOF phosphor via water induced phase transformation

Luminescent metal organic frameworks (LMOFs) with diverse structure features and promising fluorescence-based applications have attracted a wide attention in the past two decades. In this work, a LMOF with formula...

On the Formation of Hydrogen Peroxide in Water Microdroplets

Recent reports on the formation of hydrogen peroxide (H2O2) in water microdroplets produced via pneumatic spraying or capillary condensation have garnered significant attention. How covalent bonds in water could break...
