A molecular engineering principle in which repeat units of fairly rigid fused bicyclic structure and alkenes, separated by freely rotating single bonds, is proposed by Gregory A. Sotzing, Yang Cao, and co‐workers in article number 2000499 for energy storage at elevated temperatures. The piston‐like crankshaft structure endows the system with a large bandgap of ≈5eV and flexibility, while being temperature‐invariantly...
Flexible dielectrics operable under simultaneous electric and thermal extremes are critical to advanced electronics for ultrahigh densities and/or harsh conditions. However, conventional high‐performance polymer dielectrics generally have conjugated aromatic backbones, leading to limited bandgaps and hence high conduction loss and poor energy densities, especially at elevated temperatures. A polyoxafluoronorbornene...
This paper presents a steady performance analysis of an isolated three-phase self-excited induction generator which employs a three-phase winding in series connection with two capacitors and supplies for single-phase load. Performance analysis is derived by the method of symmetrical components, from which the input impedance of the generator can be determined. The voltage unbalance factor is computed...
This paper introduces a single-channel high-speed SAR ADC design. The new design uses asynchronous timing and split capacitor array to improve the ADC speed. It uses bottomplate sampling to improve the ADC linearity. A new comparator is designed to keep the capacitance at its gate constant over the bit cycling procedure so as to keep the comparator offset constant. Circuits are integrated in the comparator...
High permittivity polymer-based composites have attracted increasing attention because of their inherent advantages of being easy to process, flexible and light weight in electronic and electrical industry. However, the permittivity of common polymer is very low (<10). Adding conductive fillers provides a promising route to significantly increase the permittivity of a polymer with a low loading...
