ABSTRACT Highly crosslinked polyethylene (XLPE) has revolutionized total hip arthroplasty (THA), but increased radiation doses and complex crosslink structures may increase oxidation susceptibility. The long‐term oxidative stability of XLPE depends on manufacturing factors, including crosslink density, antioxidant (vitamin E) concentration ...

Recent update on crosslinked polyethylene in total hip arthroplasty
More than two decades after their clinical introduction, crosslinked polyethylenes (XLPE) have been widely adopted. Though concerns were initially raised regarding oxidation and brittleness, on a large scale, the first generation of XLPE continues to be ...

ABSTRACT A time domain pulse (TDP) based on the frequency domain reflectometry (FDR) method can be used to diagnose the insulation state of cable defects. However, because of the limitations of the FDR test instrument, the lack of a reflection coefficient spectrum (RCS) in the low‐frequency band (LFB) can result in low frequency oscillation in the time

ABSTRACT Wind energy has become one of the most promising new energy resources. In the construction of offshore wind farms, the cable accounts for about 10% of the total investment, and the optimization of the cable layout is necessary for reducing the total cost of the wind farm. In this paper, we proposed a novel algorithm for the optimization of the

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...
