Evaluation of geological engineering factors for productivity of deep CBM well after fracturing based on grey correlation method

open access: yesYouqicang pingjia yu kaifa, 2023
Coal-bed methane reservoirs are characterized by low porosity, low permeability and low pressure, making their industrial exploitation primarily reliant on techniques like hydraulic fracturing. Currently, more than 50 percent of the gas wells in the Shizhuang block in the Qinshui Basin currently produce less than 500 m3/d of coal bed methane.

Multiscale Perspectives on Perovskite Instability: From Atomistic Deformation to Device Degradation in Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

Gas Content and Gas Occurrence Mechanism of Deep Coal Seams in the Shenfu-Linxing Block

open access: yesEnergies
The Shenfu-Linxing block in the Ordos Basin holds abundant deep coalbed methane (CBM) resources, which can alleviate gas shortages and aid dual carbon target achievement. Considering isothermal adsorption traits and parameters like vitrinite reflectance,

Discrimination of Lipid Hydroperoxide Positional Isomers Using SFC–MS/MS With Sodium Ion: Its Application to Evaluating the Oxidation Mechanisms of Oxidized Oils

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Advanced lipid profiling relies on liquid chromatography–tandem mass spectrometry (LC–MS/MS), but long analysis times remain a challenge. Supercritical fluid chromatography (SFC)–MS/MS using supercritical carbon dioxide offers a faster and more environmentally friendly alternative.

Research progress and breakthrough directions of the key technical fields for large scale and efficient exploration and development of coalbed methane in Xinjiang

open access: yesMeitan xuebao
The Xinjiang Uygur Autonomous Region has presented the expected resource conditions and work foundations for a large-scale coalbed methane (CBM) exploration and development, which shows that its CBM resources below the depth of 2000 m are 7.5 trillion m3,

Higher complement C4 gene copy number constitutes a shared genetic risk factor for giant cell arteritis and IgA vasculitis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Prosocial behaviour in primary and secondary school students. Effects of the CYBUPRE intervention

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Prosocial behaviour is regarded as a critical factor in reducing aggressive behaviours among peers, both in physical settings and virtual spaces. This variable facilitates the enhancement of social relationships, promoting empathy, deep listening, physical and verbal service, and even solidarity, among other benefits.

Sustainability‐Oriented Innovation and Circular Economy Transitions: Evidence From the UK Textile and Clothing Industry

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The transition to a circular economy (CE) in the textile and clothing (TC) industry is frequently attributed to sustainability‐oriented innovation (SOI), yet empirical understanding of the systemic conditions under which SOI enables CE remains underdeveloped.
