Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

open access: yesHigh Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Optimised Molecular Traps and Conjugated Structures for Superior High‐Temperature Capacitive Performance in Polyimide

open access: yesHigh Voltage, EarlyView.
ABSTRACT In the fields of automotive electronics, power electronics, and aerospace, environmental conditions are often extremely harsh, particularly for materials that must endure high temperatures, high power and require high stability. The degradation of capacitance performance in polymer dielectrics under high electric fields and elevated ...

Effect of molecular perturbation on cocrystal formation: theophylline and its 8‐halo analogues with flavonoids

open access: yesActa Crystallographica Section C, EarlyView.
The tendency for alkaloid–flavonoid cocrystal formation is found to be markedly different for theophylline (Tph) compared to its 8‐halo analogues. Through screening with 13 common flavonoids, Tph is found to form cocrystals with six flavonoids, whereas 8‐Cl‐Tph and 8‐Br‐Tph each form cocrystals with just two, myricetin and kaempferol.
