Programmable Nanoscale Motion via Molecular Patterning on DNA Origami

open access: yesAngewandte Chemie, EarlyView.
DNA origami nanorods enable precise urease placement with tunable coverage and asymmetry, revealing that propulsion depends on a balance of catalytic loading and geometry. Maximum speed occurs at ∼25% end‐coverage and declines as enzyme distribution becomes more symmetrical.

Experimental Observation of a Calcium Silicon Double Carbonate

open access: yesAngewandte Chemie, EarlyView.
High‐pressure and ‐temperature reactions between Ca5(Si2O7)(CO3)2 tilleyite and CO2 carbon dioxide yield the first experimental evidence of the double carbonate Ca2Si(CO3)4 and a new Ca2(C4O10) phase containing tetrahedral [CO4] units. These findings reveal unexpected carbonate chemistry and highlight pathways for carbon incorporation under mantle ...

Molecular Electrocatalyst Enables Direct Electrochemical Capture and Conversion of CO2 up to Atmospheric Concentration

open access: yesAngewandte Chemie, EarlyView.
A molecular manganese electrocatalyst enables the direct electrochemical capture and conversion of dilute CO2 (1% – 0.2%) to CO with nearly unit Faradaic efficiency, achieving high efficiency even at atmospheric concentrations (420 ppm). By bypassing energy‐intensive pre‐concentration steps, this integrated approach highlights a sustainable pathway for
