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

Ecography, EarlyView.Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

High‐Entropy Metal Phosphide for Efficient Hydrogen Conversion Reactions
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.In this study, high‐entropy metal phosphide nanoparticles were synthesized via a cation‐binding phosphate–resin heating treatment strategy. Mn incorporation in Co0.62Fe0.20Ni0.14Cu0.23Mn0.38P effectively optimized the electronic structure, accelerated electron transfer among metal sites, lowered the free energy of hydrogen adsorption/desorption, and ...
