Theoretical and experimental investigation of compensation-chamber effects in an open-loop heat pipe

An open-loop heat pipe (OLHP) with a circular flat evaporator was developed by opening the liquid return path of a conventional loop heat pipe (LHP). Condensate is discharged from the condenser as product water, while feedwater is supplied externally to the compensation chamber....

Tuning Polarization Fields in Zwitterionic Covalent Organic Frameworks for Efficient Photo‐Assisted Rechargeable Zinc–Air Batteries

ABSTRACT Covalent organic frameworks (COFs) with tunable topologies hold great promise for photoelectrochemical energy conversion. However, their inherently high structural symmetry and weak intramolecular polarization typically cause rapid charge recombination, thereby severely...

Dynamic Voltage-Response Estimation for Blade-Tip Timing Sensors Based on EHHO-BP Network and Waveform Mapping

Blade-tip timing (BTT) sensor technology is widely used for non-contact blade vibration measurement. However, conventional BTT methods mainly rely on sparse time-of-arrival (TOA) information, which limits continuous sensor-domain characterization of blade vibration. To address th...
