Embedded Fe‐Cu Pairs Enable Tandem Nitrate‐to‐Ammonia Electroreduction

open access: yesAdvanced Materials, EarlyView.
A tandem Fe‐Cu pair catalyst, composing a single copper atom (Cu–N3) coordinated to adjacent iron clusters (Fe3N8), is designed. The electron‐deficient copper sites markedly enhance nitrate adsorption, while the electron‐rich iron clusters facilitate nitrite adsorption and water activation, thereby accelerating the electroreduction of nitrate and ...

Morphology vs. Specific Surface Area: Which Plays the Leading Role in Microwave Absorption?

open access: yesAdvanced Materials Interfaces, EarlyView.
The role of morphology and specific surface area on microwave absorbing characteristics is systematically evaluated and compared. The matrix effect on microwave absorbing performance is studied using polyacetylurea. Implanted carbon nanotubes by red phosphorus and in situ polymerization of polyindole promoted microwave absorption.

Numerical Aperture Dependence of Mie Modes in Low Refractive Index Particles and Enhanced Collection Using Metallic Substrates

open access: yesAdvanced Optical Materials, EarlyView.
The influence of numerical aperture (NA) on the detection of Mie resonances in dielectric spheres is demonstrated. Experiments and simulations reveal that varying NA modifies mode amplitudes and linewidths. Furthermore, metallic substrates redirect modes toward low angles, enabling efficient mode detection with low NA optics and reducing perturbation ...
