Abstract Volatile solid (VS)‐additives are regarded as an effective tool to manipulate morphology of sequential deposited (SD) active layers for improving power conversion efficiencies (PCEs) organic solar cells (OSCs), while the independent effect VS‐additives on donor and acceptor is often overlooked. Herein, a new VS‐additive named 2‐(2‐methoxyphenyl)benzo[ b ]thiophene (BTO) synthesized applied in SD binary PM6/L8‐BO layers. Introducing it into bottom PM6 layer (PM6 + ), BTO has low...
The complex resistivity (CR) measurement constitutes a practical methodology for investigating the internal structures of rocks and ores alongside their mineralogical compositions chemical properties fluids. However, during testing, particularly at high frequencies, leakage current caused by distributed capacitance instrument’s acquisition channels reduces accuracy. Additionally, contact impedance measuring devices electromagnetic coupling effects cables further affect test results samples....
This study investigates the acid–rock reaction kinetics and their implications for enhancing tight limestone reservoir stimulation through systematic experiments. Using 14 cores, we evaluate dynamic behavior of single-phase gelled acids (12%, 15%, 20% HCl) under controlled conditions (80 °C; 10–180 min). Three key findings emerge: (1) initially exhibit higher rates (0.897%/min) compared to (0.453%/min at 10 min), but efficiency converges over extended durations; (2) both acid types follow...
CO2 flooding technology has been established as a key technique that is both economically viable and environmentally sustainable, achieving enhanced oil recovery (EOR) while advancing CCUS objectives. This study addresses the challenge of optimizing well patterns in tight reservoirs through geological–engineering integrated approach. A semi-analytical model incorporating startup pressure gradients miscible/immiscible two-phase flow was developed to dynamically adjust injection intensity. An...
Research on the electrical properties of rocks and ores plays a crucial role in development geophysical electromagnetism methods. However, currently available instruments suffer from high power consumption, limited number electrodes, inaccurate measurements, poor portability, ability to measure parameters ores. To address these issues, this paper presents three-dimensional impedance tomography system for rock samples with high-density microelectrodes based an Android STM32 microcontroller....
Hydraulic structures, such as shiplocks, are typically surrounded by backfills, leading to various contact interactions between the backfills and outer surfaces of structures.To investigate evolution contacts under different loading conditions across entire structure explore influences on stress distributions shiplock soil, three-dimensional numerical analysis was conducted lock head a shiplock, considering scenarios interactions.Results show that, opening areas displacements vary...
An integrated model that considers multiphysics is necessary to accurately analyze the time-dependent response of hydraulic structures on soft foundations. This study develops an superstructure–foundation–backfills and investigates displacement stress a lock head project foundation during construction period. Finite element analyses are conducted, incorporating transient thermal creep for concrete elasto-plastic consolidation soil. The modified Cam-clay employed describe behavior...
Cu is commonly used to improve the mechanical properties of Al–Li alloys, but its exact role in multicomponent alloys not fully understood. Herein, microstructure and two cast Al–2.6Li–2.8Mg–(0.5, 1.4)Cu–0.2Zr–0.2Sc (wt%) aged at 165 °C are compared. The results show that Alloy 1.4Cu possesses finer grain size better than 0.5Cu. δ′ (Al 3 Li), Al (Sc, Zr, Li) phases, Guinier–Preston–Bagaryatsky zones formed both alloys. During early stage ageing (8 h), many dispersed S′ 2 CuMg) phases...
Increases in the penetration depth of laser welding has gained undoubted interest, especially aerospace, power station, ship building, and other heavy industries. Gas-jet-assisted keyhole is a prospective method for improving conventional welding. A series experiments using this were conducted with different parameters assisted gas jet speed. The microstructures weld joints observed optical microscopy, microhardness was also measured. investigation results showed that increased by more than...
This paper focuses on the decision of a manager or supervisor to delegate task responsibility one more employees as delegation, DOA for short; It also influence globalization workplace empowerment system and proposes that mixed cultural environment, authority leaders is not only based actual ability but subjective cognitive decision-making. Globalization has made technological skills available international market, governments non-profit organizations need establish cross-cultural systems...
