Resistivity Change Mechanism in the Carbon Dioxide Sequestration Process
Energy Science &Engineering, EarlyView.This study explores the variation law, influencing factors, and mechanisms of resistivity in the interaction between CO₂ and saltwater. This study used a hollow PEEK conductor to simulate core pores. With excellent thermal stability, mechanical strength, and electrical insulation, its homogeneous, nonporous nature eliminates interference from rock ...

Research on the Mechanism of Sand Bridge Stuck Drill in Deep Coal and Rock Gas Horizontal Wells
Energy Science &Engineering, EarlyView.Accounting for wellbore collapse debris and the bulldozer effect, this study develops models for permeable and impermeable sand bridge sticking in deep CBM horizontal wells, deriving resistance and volume formulations. Validated in Changqing, results show impermeable bridges dominate; controls (fluid optimization, staged drilling, circulation, speed ...

Energy Science &Engineering, EarlyView.This study concluded that wider spray angles produce wall impingement and greater unburned hydrocarbons in methane‐diesel dual‐fuel engines, whereas 110° balances efficiency and emissions. ABSTRACT A diesel methane dual fuel engine appears as a potential means for lowering emissions while retaining useful thermal efficiency.

Energy Science &Engineering, EarlyView.This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.

A Mathematical Model for Two‐Phase Flow in Confined Environments: Numerical Solution and Validation
International Journal for Numerical Methods in Fluids, EarlyView.We present a numerical framework based on the Cahn‐Hilliard‐Navier‐Stokes (CHNS) model to simulate biphasic flow in confined environments. After deriving the mathematical model, we develop the weak form of the system of PDEs using a pedagogical approach to enable its implementation in FEniCS.

Nonthermal Food Processing Technologies: A Comprehensive Review
Future Postharvest and Food, EarlyView.The graphical abstract illustrates the shift from traditional thermal food preservation methods to advanced nonthermal technologies. Traditional methods, represented by heating, often compromise the nutritional and sensory quality of foods. In contrast, nonthermal approaches such as high‐pressure processing (HPP), pulsed electric field (PEF ...

Malleostapedotomy in Patients With Stapes Fixation: A Systematic Review
The Laryngoscope, EarlyView.This systematic review analyses the current evidence on malleostapedotomy as a primary or revision procedure in patients with stapes fixation. Twenty‐five studies comprising 632 operated ears were included. Malleostapedotomy proved to be a safe and effective alternative to incus‐anchoring stapedoplasty, with favorable hearing outcomes and a low ...
