Selective Hydrogenation of HMF to DHMF Using Cationic Ru‐PNP Complex

ChemCatChem, EarlyView.
A novel Ru‐PNP catalyst bearing acetonitrile as ancillary ligand efficiently converts 5‐hydroxymethylfurfural to 2,5‐dihydroxymethylfuran under mild conditions (30 °C, 30 bar H₂), achieving a quantitative yield in 6 h. This catalyst outperforms the state‐of‐the‐art iPrRu‐MACHO by an order of magnitude in yield across various conditions.

A Reexamination of CO2 Reduction with Fe2S2 Hydrogenase Mimics: Lessons in Using a Hydrogen Evolution Reaction Catalyst for CO2 to Formate Catalysis

ChemElectroChem, EarlyView.
Combining cyclic voltammetry, infrared spectroelectrochemistry, and density functional theory methods, the reduction of CO2 by an [FeFe] hydrogenase mimic was examined. Despite its ability to form stable reduced hydride species, this catalyst does not selectively reduce CO2 to HCOO− under the tested conditions.

Heterogeneous Electrocatalytic CO2 Reduction by Supported Molecular Catalysts Well Dispersed on Electrode Surface

ChemElectroChem, EarlyView.
This mini review overviews the most recent advances (2020–2024) in heterogeneous electrocatalytic CO2R by well‐dispersed molecular catalysts on electrode surface, mainly focusing on the impacts of efficient molecule‐level dispersion and rational catalyst‐support interactions on electronic properties, multi‐electron transfer kinetics, and overall ...

Photogrammetric documentation in tunneling

Civil Engineering Design, EarlyView.
Abstract Photogrammetric surveys for geological excavation documentation are standard practice in tunnel construction, benefiting from the sector's ongoing digitalization. However, the application of photogrammetry often remains confined to geological assessments. By creating comprehensive 3D models of excavated tunnels, it is also possible to evaluate
