Chemistry – A European Journal, EarlyView.Despite the fact that Pt(II) in square‐planar complexes exhibits Lewis basic properties toward electrophilic species (E⁺), the presence of oxygen atoms acting as competing Lewis basic sites leads to the formation of Pt─O─E⁺─O─Pt or Pt─O─E⁺ type complexes, in which no direct metal–metal bonds are observed.

Chemistry–Methods, EarlyView.Strong external magnetic fields can keep paramagnetic porous particles static without falling down while immersed in a liquid medium, and the strength of the required magnetic field, controlled indirectly by the distance to a permanent magnet, correlates with the mass of adsorbate captured, giving rise to a new technique for quantifying adsorption ...

ChemNanoMat, EarlyView.Cobalt‐based M–N–C catalysts are evaluated for the transfer hydrogenolysis of oxidized lignin model compounds using formic acid. The synergy between cobalt nanoparticles (CoNPs) and sub‐nanometric Co(II) species in a N‐doped carbon matrix enables efficient CO bond cleavage under mild conditions.

Encapsulation Enhances the Quantum Coherence of a Solid‐State Molecular Spin Qubit
Angewandte Chemie, Volume 137, Issue 42, October 13, 2025.A purely synthetic supramolecular chemistry approach enables the protection of the spin‐based qubit [Cr(ox)3]3− from external sources of decoherence in the solid state, leading to the enhancement of the phase memory and the spin lattice relaxation time, thus validating this chemical engineering strategy for qubit implementation.

Unveiling the Direct Air Capture and Transformation to Formate Under Mild Conditions
ChemSusChem, EarlyView.Aiming to decrease CO2 emissions and proposing new green and sustainable strategies and technologies, in this research we have conducted direct air capture and transformation into formate using a sequential process. In the first step, we absorbed CO2 into an ionic liquid and then transformed into formate by using mild conditions.

Enabling a Diversity‐Oriented Catalytic Atom Looping of a Biobased Polycarbonate
ChemSusChem, EarlyView.A biobased polycarbonate shows susceptibility to switchable and chemoselective organocatalytic degradation into three primary products (P1–P3) that in turn can be further upgraded into functionalized synthons and polymerizable monomers. Selected members of these compounds have been transformed into new types of bifunctional monomers paving the way to a
