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

Bio‐Inspired Sclerotization of Lignin: A Robust Adhesive for Photothermal Wood‐Based Panels
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A high‐performance lignin adhesive is engineered via an insect‐inspired sclerotization strategy involving oxidation and hyperbranched polymer grafting, overcoming lignin's adhesion failure, and yielding a wet shear strength of 1.02–1.21 MPa. The adhesive endows wood‐based panels with photothermal functionality; building energy simulations indicate HVAC‐
