Silica‐Supported Mononuclear Methyl‐Platinum Complexes Stabilized by Trimethylphosphine—Synthesis, Structure, and Reactions Under Reducing Conditions

Chemistry – A European Journal, EarlyView.
The article describes the synthesis and molecular transformations of a silica‐supported bis(phosphine)methylplatinum(II) complex under reactive (H2, CO) and inert gas atmospheres. The focus lies on the stabilizing effect of the sterically non‐demanding trimethylphosphine ligand, which alters the reactivity of the surface sites, compared to other ...

Silver‐Mediated Deuterium Labelling of Quinones and Related Compounds by Hydrogen Isotope Exchange With D2O

Chemistry – A European Journal, EarlyView.
A new silver‐catalyzed H/D exchange reaction was developed for the labelling of quinones and related compounds. Both homogeneous and heterogeneous catalytic processes were implemented using heavy water as a simple deuterium source. The corresponding deuterated compounds were obtained with high isotopic enrichment through a practical method that opens ...

Thresholds: The metaphorical foundations of powerful knowledge

The Curriculum Journal, EarlyView.
Abstract This paper advances a theoretical account of threshold concepts as metaphorical‐relational structures that reorganise meaning across contexts. Building on conceptual metaphor theory, we propose that threshold concepts can be understood as sites of schema‐level reorganisation: deep, embodied patterns of relational logic that scaffold abstract ...

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

EcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)
