Stabilizing Atomically Dispersed Au With Adjacent Pt for Spatially Precise Molecule Recognition

Advanced Science, EarlyView.
A strategy to stabilize atomically dispersed Au catalysts by introducing Pt atoms into CeO2 supports is presented. Pt incorporation prevents Au aggregation, enhances Au‐O orbital coupling, and enables precise recognition of multi‐functionalized molecules, improving catalytic performance and the structural stability of Au‐based catalysts in ...

Enzyme‐Activated MRI for In Vivo Glucose Imaging via a Biodegradable Chromium Nanoprobe

Advanced Science, EarlyView.
Enzyme‐activated MRI (eaMRI) using a biodegradable CrGOx@Lip nanoprobe enables glucose‐specific imaging in vivo. GOx catalyzes glucose oxidation, triggering in situ formation of paramagnetic chromium gluconate and amplifying T1. This radiation‐free strategy maps tumor glucose uptake via the Warburg‐effect, quantifies hepatic glucose accumulation in ...

Solvation‐Mediated Shift From Solvent‐ to Anion‐Derived Solid Electrolyte Interphases for Stable Calcium Metal Anodes

Advanced Science, EarlyView.
An ion‐dipole interaction based strategy is proposed to capture thermodynamically unstable solvents and restructure the coordination environment of calcium ions by introducing ionic liquid co‐solvents, thus suppressing excessive solvent decomposition. Therefore, a smooth and dense solid‐electrolyte interphase dominated by inorganic components is formed

Harnessing Support‐Dependent Hydrogen Spillover for Ni‐Based CO2 Hydrogenation

Angewandte Chemie, EarlyView.
Hydrogen spillover can be harnessed for Ni‐based CO2 hydrogenation via support‐dependent pathways. Hydrogen spillover propagating to surfaces promotes catalysis through two distinct mechanisms. On moderately reducible supports, it rapidly removes poisoning oxygen species (*O) from Ni nanoparticles.
