Electronic Interaction at Cu–O–Ni Heterointerface Promotes Electrocatalytic Nitrate Reduction to Ammonia and Zinc‐Nitrate Battery

open access: yesAdvanced Science, EarlyView.
The strong Cu–O–Ni electronic interaction in the heterostructured catalyst can enhance the effective adsorption of NO3− and accelerate the in situ hydrolysis dissociation of the hydrogenation step. The Zn‐NO3 hybrid battery assembled with this catalyst achieves an open‐circuit voltage of 1.45 V, a peak power density of 6.47 mW cm−2, and can ...

Fluorinated Glycan Frameshifts: Automated Synthesis Expedites the Study of Glycan‐Protein Interactions by 19F‐BioNMR

open access: yesAngewandte Chemie, EarlyView.
Given the prominence of 19F‐bioNMR in structural research, fluorinated glycans hold enormous potential in glycomimetic frameshift design. However, challenges associated with the stereocontrolled synthesis of these disruptive actors continue to frustrate advances. To address this, the automated synthesis of selectively C‐2 fluorinated glycans related to
