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 ...

Synthesis of Coal Tar‐Based Hypercrosslinked Polymers via Friedel‐Crafts Alkylation: An Efficient Way to Access Carbon Electrode Material for Supercapacitors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Liquid coal tar (CT) is synthesized into hypercrosslinked polymers (HCPs) via the Friedel–Crafts alkylation, followed by oxidation‐carbonization to form disordered microporous carbon. The resulting CF2CT exhibits a high three‐electrode specific capacitance of 342 F g−1 at 1 A g−1, and the assembled symmetric supercapacitor illuminates a light sign ...

Pt Sub‐Nanoclusters on ZIF‐Derived Ultrafine CdxZn1−xS Solid Solution: High‐Performance Photoreforming Lactic Acid to H2 and Value‐Added Chemicals

open access: yesElectron, EarlyView.
This work presents ZIF‐derived ultrafine CdxZn1−xS decorated with Pt sub‐nanoclusters for efficient photocatalytic reforming of lactic acid. The catalyst achieves high H2 evolution (270.6 mmol h−1 g−1) and selective pyruvic acid production (73.1%), with mechanistic insights revealing Pt‐mediated control over reaction pathways.

Vanillin production from lignin depolymerization by acidic deep eutectic solvent and its possible mechanism

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract As one of the most abundant renewable resources and complex aromatic polymers, lignin holds great promise for producing monophenolic compounds. However, its depolymerization into valuable monomers is hindered by intricate side reactions. In this study, alkaline lignin was converted into vanillin using nine choline chloride‐based deep eutectic ...

Emissions Reductions and Economic Feasibility of China's Solar Thermal Power Industry After the Introduction of Chinese Certified Emission Reduction Policy

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT To promote the development of renewable energy, China re‐implemented the Chinese Certified Emission Reduction (CCER) policy in 2023. This study explores certificated CO2 and air pollutants (i.e., NOx, SO2 and particulate matter (PM)) emissions reductions from China's solar thermal power (STP) industry at national scale and conducts the ...
