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 ...

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 ...

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.

Mediations of Xinjiang: For an Aesthetic Politics

open access: yesJournal of Asia-Pacific Pop Culture, 2019
Abstract Zhang Qian’s second-century B.C.E. reports on his travels through what is now the northwestern Chinese province of Xinjiang begin two millennia of mediations of this large and fraught region. This article’s consideration of mediations on landscape begins with Tsui Hark’s film Seven Swords, looking back to drawing and photography,

Structural change and spatial pattern of urbanization in Xinjiang

open access: yes, 2010
Xinjiang has experienced considerable urban growth in the past sixty years, especially since the implementation of socio-economic reforms in 1978. When Xinjiang was founded as a Uygur Autonomous Region in 1955, there were only three cities with an urban ...

Anchoring MoS2 Petal‐Like Nanosheets on Coal‐Based Carbon Nanofibers by Surface Bonding Enable Li+/Na+ Batteries to Achieve Fast‐Charging Capabilities

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The unique structure connected by CS and COS interfacial bonds accelerates the reaction kinetics of lithium/sodium‐ion storage, while the addition of coal led to an increase in the mechanical strength of the carbon nanofibers, which improved the conductivity and stability of the materials.
