Carboxyl‐Guided Ultrafine Zinc‐Acetate Templating Enables Closed‐Pore Engineering in Coal‐Derived Hard Carbon Anodes for High‐Performance Sodium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
In this study, ≈2 nm zinc acetate templates are uniformly anchored on the surface of NaOH‐etched bituminous coal via chelation between carboxyl groups and Zn2+. Subsequently, phenolic resin encapsulation is employed to construct a hard carbon material with abundant closed‐pore structures, achieving a reversible capacity of 370.9 mAh g−1 and an ICE of ...

Brillouin Microscopy of Breast tumor Spheroids On‐a‐Chip: Mechanical and Transcriptional Responses to Microfluidic‐Induced Rapid Deformations

open access: yesAdvanced Science, EarlyView.
Brillouin‐Raman Microspectroscopy on‐a‐Chip (BRmS) enables real‐time analysis of breast tumor spheroids in microfluidic channels. Following cyclical deformations, MCF10.DCIS.com spheroids are captured in recovery traps and imaged with BRmS. The applied deformations trigger a stiffening response marked by increased frequency shifts, elevation of the ...

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

open access: yesAdvanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought
