An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

Deep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

Entropy‐Driven Design of Stable High‐Performance Sodium‐Ion Battery Cathodes

EcoEnergy, EarlyView.
This review explores high‐entropy strategies for advanced sodium‐ion battery cathodes, focusing on LTMOs and PBAs. It details how entropy engineering mitigates challenges: phase transitions, interface degradation, and air instability in LTMOs; vacancy defects and crystalline water in PBAs.

Entropy‐Stabilized Pd/HEO Bifunctional Catalyst for Selective Aqueous‐Phase Hydrogenolysis of Cellulose to Ethylene Glycol

EcoEnergy, EarlyView.
An entropy‐stabilized Pd/HEO catalyst integrates Lewis acid and hydrogenation sites within a robust oxide–metal interface, enabling efficient and selective conversion of cellulose to ethylene glycol (68.3%) in water. ABSTRACT The selective conversion of cellulose into ethylene glycol (EG) under aqueous conditions is an attractive yet challenging route ...

Synergistic Enhancement of Modified‐PVDF Humidity Sensitivity via Chemical Adsorption‐Ionic Conductivity and its Application in Intelligent Powered Air‐Purifying Respirator

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The study developed a PVDF/SiO2 humidity sensor with superhydrophobic properties and integrated the humidity sensor into the intelligent powered air‐purifying respirator (IPAPR) for breath monitoring. Coupled with the Gated Recurrent Unit (GRU) machine learning prediction algorithm, it enables feedforward control of the fan to achieve respiratory ...
