Engineering Mechanically Adaptive Nanonetworks for Long‐Life and High‐Capacity Silicon Anode Batteries

open access: yesCarbon Energy, EarlyView.
ABSTRACT Silicon anodes, with a theoretical capacity of ~ $\unicode{x0007E}$3860 mAh g−1, offer more than ten times the lithium storage of graphite but suffer from large volume expansion during lithiation, leading to particle fracture, electrical disconnection, and unstable solid–electrolyte interphases (SEIs).

Turning Disorder Into Advantage: Precisely Tailored Hybrid Phase Interfaces in B‐Doped High‐Entropy (FeCoNiCrMn)3O4 for Lattice Oxygen‐Mediated Seawater Electrolysis

open access: yesCarbon Energy, EarlyView.
This study designs boron‐doped high‐entropy oxide nanosheets with crystalline‐amorphous interfaces. This tailored disorder promotes a lattice‐oxygen‐involved reaction pathway, significantly enhancing the oxygen evolution efficiency and chloride corrosion resistance during seawater electrolysis. It demonstrates a new design principle of using controlled

Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

open access: yesChemistry – A European Journal, EarlyView.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Controlling Structures and Properties of NaCl‐Containing Alginate/Polyacrylamide Tough Hydrogels via a One‐Pot Process

open access: yesChemistry – A European Journal, EarlyView.
NaCl‐incorporated alginate/polyacrylamide tough hydrogels are prepared through a facile one‐pot strategy that enables direct ion incorporation during network formation. Compared with conventional soaking, this approach reduces diffusion‐limited ion gradients and provides a more spatially consistent ion distribution.

Investigation on the failure evolution characteristics of surrounding rock in deep cross‐fault roadway: Based on physical model test and numerical simulation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study reveals the failure evolution characteristics of deep cross‐fault roadway surrounding rock under excavation support and periodic weighting. Periodic weighting readily induces fault activation, with the spatial distribution of failed rock masses being controlled by the fault strike and dip.

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

open access: yesDeep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...
