The low intrinsic thermal conduction and high dielectric properties of epoxy resins have significantly limited their applications in electrical electronic devices with integration, frequency, power, miniaturization. Herein, a liquid crystalline (LCE) monomer biphenyl mesogenic unit was first synthesized through an efficient one-step reaction. Subsequently, bisphenol AF (BPAF) containing low-polarizable −CF3 groups 4,4′-diaminodiphenylmethane (DDM) were applied to cure the LCE commercial...
Abstract The low thermal conductivity, poor toughness, and non‐reprocessability of thermosetting epoxy resins severely restrict their applications sustainable development in flexible electronics. Herein, liquid crystalline (LCE) dynamic ester disulfide bonds are introduced into the cured network bisphenol A resin (E‐51) to construct highly thermally conductive (LCER) vitrimers. LCER vitrimers demonstrate adjustable mechanical properties by varying ratio LCE E‐51, allowing it transition from...
Urban street comfort is a crucial measure of environmental quality. However, traditional evaluations primarily focus on physical elements, often neglecting pedestrian perceptions. In this study, considering five core evaluation dimensions—safety, mobility, aesthetics, perceptibility, and convenience—an innovative quantitative model proposed to assess pedestrian-perceived urban streets by integrating factors subjective experiences. This analysis comprises two steps: indicator extraction...
This paper describes design and operation of a three-phase HTS power transformer with capacity 630 kVA operated in liquid nitrogen 77 K for primary/secondary voltages 10.5 kV/0.4 kV. The windings were wound by hermetic stainless steel-enforced multifilamentary Bi2223/Ag tapes. structures primary secondary are solenoid double-pancake respectively. Cryostat is made from electrical insulating materials room temperature bore commercial amorphous alloy core. Fundamental characteristics the...

An extended interaction klystron (EIK) working at the frequency of 340 GHz is designed in this present article. The characteristic impedance, coupling coefficient, and normalized electron conductance cold cavities are analyzed optimized. To improve output power, EIK adopts a prebunching (PB)-cavity high-frequency structure (HFS). Compared with conventional terahertz (THz) EIK, coherence PB-cavity enhanced, power improved. 3-D particle-in-cell (PIC) simulation predicts driven by 0.20-A,...
