s‐Orbital Mediated Metavalent Bonding Enables State‐Of‐The‐Art n‐Type AgBiSe2 Thermoelectrics
Metavalent bonding (MVB) underpins the exceptional property portfolio of chalcogenides. Typical MVB solids are mainly found in p‐bonded systems. This work reveals that MVB can also be formed with s‐p orbital interactions upon forming a single‐electron σ‐bond, as exemplified in AgBiSe2.

Stabilizing Frustrated Phase Transitions in Selective Oxidation Reactions
Using multimodal operando spectromicroscopy, the frustrated phase transition responsible for selective oxidation over cobalt oxide spinel catalysts is identified, corresponding to combined surface reaction and Mars‐van Krevelen (MvK) dynamics. This regime is disrupted by the formation of mobile vacancies and the depletion of active oxygen at high ...

N‐heterocyclic Carbenes as Adhesion Promoters on Aluminum Alloy 6061
N‐heterocyclic carbenes as novel non‐toxic surface primers for aluminum alloys for better adhesive bonding, because strong adhesive bonding shouldn't come at the cost of poisoning the human body. The impact of NHC functionalization on adhesive joint strength and durability is also evaluated using a single‐lap‐shear test, following continuous exposure ...
