Unfolding of the Villin Headpiece Domain: Revealing Structural Heterogeneity with Time‐Resolved X‐Ray Solution Scattering and Markov State Modeling

ChemPhysChem, EarlyView.
The unfolding of villin headpiece 35 (HP35) and a double‐norleucine variant (2F4K) using a temperature‐jump and time‐resolved X‐ray solution scattering is examined. HP35 displays a two‐state kinetic model, while 2F4K indicates a transient intermediate.

Protonation of Pt(IV) Anticancer Complexes Assayed by Vibrational Ion Spectroscopy

ChemPlusChem, EarlyView.
Protonated Pt(IV) complexes with various equatorial and axial ligands were characterized by IR ion spectroscopy and DFT. Protonation typically occurs at carboxylato ligands, eventually increasing their substitution propensity. However, the carboplatin‐derived complex showed mixed protomer populations, highlighting the significance of ligand selection ...

Extensive Fragmentation, Atom Transfer, H loss and Cross‐linking Induced by Single Collisions between Carbon Ions and Protonated Antibiotics in the Gas Phase

ChemPlusChem, EarlyView.
The direct effects of ionizing radiation on antibiotics are largely unknown. Thanks to experiments where antibiotics in the gas phase are irradiated by a carbon ion beam, we find that upon single carbon ion collision, isolated antibiotics undergo ionization, extensive fragmentation, proton and/or sodium transfer as well as abundant loss of H from ...

Electrocatalytic CN Coupling: Advances in Urea Synthesis and Opportunities for Alternative Products

ChemSusChem, EarlyView.
This review explores electrocatalytic urea synthesis via carbon–nitrogen (CN) coupling from CO2 and nitrogen species, specifically nitrate, nitrite, nitric oxide, and nitrogen gas. It discusses recent discoveries in catalyst design, reaction pathways, and detection methods. Future outlooks on industrial applications, alternative CN coupling products,

The Role of Metal–Organic Framework Induced Confinement Effects on Molecular Electrocatalysts Relevant to the Energy Transition

ChemSusChem, EarlyView.
In this review, the performance of a series of electrocatalysts confined in MOFs is compared to that of the corresponding homogeneous catalysts to evaluate to what extend the catalytic site is affected by confinement in terms of stability, activity and selectivity.
