Enabling Wide‐Temperature Range Li‐S Batteries via Asymmetric‐Coordinated Titanium Sites‐Implanted Graphene Single‐Atom Electrocatalysts

open access: yesCarbon Energy, EarlyView.
A Ti‐based single‐atom catalyst featuring isolated Ti atoms anchored on reduced graphene oxide (Ti‐rGO) has been successfully synthesized as a sulfur host material. This Ti‐rGO composite effectively integrates the robust adsorption capacity of Ti‐O5 coordination groups toward LiPSs with the rapid mass transport kinetics inherent to its porous ...

Insights Into the Effect of Humic Acids Extraction From Coal on Hard Carbon Microstructure and Sodium Storage Properties

open access: yesCarbon Energy, EarlyView.
This study employs a simple solid‐phase alkali‐oxygen oxidation (SAO) method to extract inherent components (humic acids) from coal. We successfully extracted yellow, brown, and black humic acids by adjusting the amount of alkali. Among them, brown humic acid extraction created abundant ultra‐micropores and closed pores, greatly enhancing sodium ...

Migration of the Population from the Ili Region to the Russian Empire after the Ili Crisis (Based on Materials from the Newspaper “Eastern Review”)

open access: yesЖурнал Фронтирных Исследований
The Ili crisis in Russian-Chinese relations led to the intensification of migration processes in the region. The local population was seriously concerned about the consequences of the presence of Qing troops after the departure of the Russians.

Permeability of granite from a shallow buried mountain pipe gallery tunnel under unloading confining pressure

open access: yesDeep Underground Science and Engineering, EarlyView.
Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

Migration, Risk and Livelihoods: A Chinese Case [PDF]

open access: yes, 2010
China has turned from a ‘low risk’ to a ‘high risk’ society since the start of the market reforms in the late 1970s. Market, while bringing diverse livelihood opportunities to rural people, has simultaneously distributed risks, and the exposure and ...

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

open access: yesDeep Underground Science and Engineering, EarlyView.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Constructing Interface‐Enhanced S‐Heterojunctions Via Surface Functionalization Strategies to Improve Photocatalytic Hydrogen Production Efficiency in Inorganic/Organic Composite Systems

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A surface in situ growth strategy was employed to fabricate a COF/TiO2 S‐scheme heterojunction with enhanced interfacial forces. This enhanced interfacial heterojunction significantly improved photocatalytic hydrogen production capacity. S‐scheme heterojunctions play a crucial role in enhancing charge‐carrier separation efficiency and redox capability.
