Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Most High-density Exoplanets Are Unlikely to Be Remnant Giant Planet's Cores

open access: yesThe Astrophysical Journal Letters
Some exoplanets have much higher densities than expected from stellar abundances of planet-forming elements. There are two theories—metal-rich formation hypothesis and naked core hypothesis—that explain how formation and evolution can alter the ...

Make‐Use‐Remake: Toward Indefinite Low‐Temperature Material Loops

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a regenerable materials platform built from microparticles bound by a temperature‐responsive polymer shell, enabling strong, processable structures from diverse feedstocks. The material is shaped at low temperatures (80°C) using common manufacturing methods and reprocessed repeatedly in the presence of water, demonstrating stable ...

Multicomponent Peptide‐MXene‐Hyaluronic Acid Hydrogel as a Conductive Scaffold for Enhanced Fibroblast Proliferation and Migration Under Electrical Stimulation

open access: yesAdvanced Healthcare Materials, EarlyView.
An electrically conductive FmocFF/MXene/hyaluronic acid hydrogel combines extracellular matrix‐like architecture, self‐healing behavior, oxidation‐resistant conductivity, and biochemical cues in a single scaffold. By enabling physiologically relevant electrical stimulation, the platform enhances fibroblast attachment, proliferation, and migration ...

Simultaneous Evolutionary Fits for Jupiter and Saturn Incorporating Fuzzy Cores

open access: yesThe Astrophysical Journal Letters
With the recent realization that there likely are stably stratified regions in the interiors of both Jupiter and Saturn, we construct new nonadiabatic, inhomogeneous evolutionary models with the same microphysics for each that result at the present time ...

Radio Continuum Spectra of Planetary Nebulae

open access: yesGalaxies, 2018
Radio continuum emission of planetary nebulae is a rich source of information about their structure and physical parameters. Although radio emission is well studied, planetary nebulae show higher spectral indices than expected for homogeneous sphere.
