Defect‐Engineered Multi‐Intermetallic Heterostructures as Multisite Electrocatalysts for Efficient Water Splitting

open access: yesAdvanced Science, EarlyView.
A self‐supporting nanoporous multicomponent CoCuMoNi catalyst is synthesized. Through the synergistic effect of multiphase interfaces, built‐in electric fields, and defect engineering, the binding energy of key reaction intermediates in hydrogen evolution reaction (HER)/oxygen evolution reaction (OER) is modulated, achieving high activity and stability

Analysis of Close Encounters With Ganymede and Callisto Using a Genetic n-Body Algorithm

open access: yesFrontiers in Astronomy and Space Sciences, 2018
In this work we describe a genetic algorithm which is used in order to study orbits of minor bodies in the frames of close encounters. We find that the algorithm in combination with standard orbital numerical integrators can be used as a good proxy for ...

Accelerate Mass Transport of Proton and Carbon Sources by Super‐Hygroscopic and Porous Nanosheets for Continuous CO2‐To‐Ethylene Upgrade

open access: yesAdvanced Science, EarlyView.
The conceptual diagram of the Tillandsia and a localized enlargement of its leaves. Abstract Gas‐water/catalyst triple‐phase interface and the microenvironment play critical roles in the reaction kinetics and production rate of electrochemical carbon dioxide reduction reactions (CO2RR), which steer concerted proton‐electron transfer steps.

AuCu@CuO2 Aerogels with H2O2/O2 Self‐Supplying and Quadruple Enzyme‐Like Activity for MRSA‐Infected Diabetic Wound Management

open access: yesAdvanced Science, EarlyView.
The AuCu@CuO2 aerogels demonstrate favorable photothermal properties, four types of enzyme‐like activities, and H2O2/O2 self‐supplying to modulate the complex microenvironment of MRSA‐infected diabetic wounds. The results indicate that the AuCu@CuO2 aerogel can be activated by the microenvironment of diabetic wound infection, alleviating inflammation ...

Mercaptophenylboronic Acid‐Mediated Nanozyme Immunochromatographic Assay for Simultaneous Detection of Respiratory Bacteria and Virus

open access: yesAdvanced Science, EarlyView.
This study developes a universal colorimetric ICA platform that integrates broad‐spectrum recognition by 4‐mercaptophenylboronic acid with dual signal enhancement—both colorimetric and catalytic—mediated by a biomimetic magnetic nanozyme. This platform, for the first time, enables simple, convenient, ultrasensitive, and simultaneous screening of ...
