Synergistic Reaction Pathway Regulation and Process Simulation of Piperazine-Promoted AMP-EG Water-Reduced Absorbents for Low-Energy CO2 Capture

Abstract An AMP-PZ-EG-H2O water-reduced absorbent was developed for CO2/CH4 separation in natural gas decarbonization. Promoter screening and composition optimization identified PZ as the preferred promoter and an AMP/PZ mass ratio of 2:1 with a total AMP-PZ-EG mass fraction of 5...

Molecularly Imprinted Polymer-Based Biosensors for Disease Biomarker Detection and Environmental Monitoring from Fundamental Principles to Emerging Applications

Molecularly imprinted polymers have emerged as robust synthetic recognition materials for selective detection of disease biomarkers and environmental contaminants owing to their high physicochemical stability, low production cost and tunable binding site architecture. Compared wi...

Multi-channel VACNTs Enabling Efficient Electron Percolation Networks in Lithium-Ion Battery

Abstract Traditional carbon black conductive agents have become indispensable in lithium-ion batteries because of their low cost. However, their high load and conductive gap limit the performance of lithium-ion batteries. This study employs vertical gas-supply chemical vapor depo...

Pressure-Controlled Drainage Strategy for Deep Coalbed Methane Wells Considering Stress Sensitivity

China’s deep coalbed methane (CBM) resources hold significant development potential, yet their commercial exploitation remains hindered by four interrelated reservoir challenges: substantial burial depth, elevated in situ stress, ultra-low matrix permeability, and pronounced stre...

Study on the Hydraulic Fracture Propagation Mechanism in Deep Coalbed Methane Reservoirs of the Yan’an Gas Field

To address the unclear fracture propagation behavior and the insufficient understanding of the influence mechanisms of fracturing parameters during the hydraulic fracturing of deep coalbed methane reservoirs in the Yan’an Gas Field, Well JY1 in the No. 8 coal seam of the Benxi Fo...

Interactions between Photochemical and Microbial Degradation on the Pyrogenic Soil-Derived Dissolved Organic Matter

Abstract Photochemical and microbial processes act as primary pathways regulating the transformation and fate of pyrogenic dissolved organic matter (pyDOM) in natural environments, yet their interactions remain poorly understood under different heating conditions. Here, we combin...

Integrated Dynamic Evaluation and Prospect Screening for Infill-Well Optimization in a Tight Sandstone Gas Reservoir

As a typical tight sandstone gas reservoir, the study area has entered a production-decline stage after years of development, and well pattern infilling has become a key means of improving the recovery factor. A cluster-analysis-based classification divided the reservoir into thr...

Leveraging skybridge in coupled cylindrical storage tanks to mitigate seismic vibration

This study investigates the mitigation of excessive vibrations in two adjacent elevated storage tanks exposed to sequential nonstationary seismic excitations with time-varying frequency content. The coupling between the adjacent tanks is achieved through a sky-bridge structure th...

Research advances in metal halides for flexible indirect X‐ray imaging

Abstract In recent years, metal halides (MHs) have emerged as ideal materials for indirect X‐ray detection scintillators due to their superior radiation luminescence properties, tunable luminescence, and low‐cost fabrication. However, rigid scintillators often suffer from dark co...

Low-Carbon Valorization of Waste PE Mulch Film: A Carbon Footprint Comparative Analysis of Typical End-of-Life Treatment Pathways

Widespread polyethylene (PE) mulch film application has caused severe farmland plastic pollution and greenhouse gas emissions. To identify low-carbon end-of-life pathways for waste agricultural mulch film, this study established a full life-cycle carbon footprint model comparing...
