Dielectric film capacitors are used in diverse areas of social production due to their rapid charge and discharge rates, strong self-healing properties, and high breakdown strength [1], [2], [3], [4], [5]. Nonetheless, their intrinsic limitations of inadequate temperature resistance and susceptibility to high-temperature degradation, restrict their utility in specialized operational contexts, like hybrid vehicles, aerospace applications, and oil well investigations [6], [7], [8].

Dielectric polymers have attracted considerable interest for a variety of values in compact electronic devices because of their excellent performance, such as low energy dissipation, great reliability.[1], [2], [3], [4] For example, the dielectric capacitors have been widely used in hybrid electric vehicle (HEV) inverters to convert DC from the batteries to the AC to drive the motor[5], [6], [7].

1. IntroductionSynthetic aperture radar (SAR) is widely mounted on aerial platforms such as airplanes due to its weather-independent and day-and-night sensing capability to obtain high-resolution images over long distances [1,2,3,4,5]. It has been applied in various fields, such as environmental monitoring, ground surveying, and target detection.

AbstractMacrophages are heterogeneous cells that play multifaceted roles in cancer progression and metastasis. However, the phenotypic diversity of tumor-associated macrophages (TAMs) in head and neck squamous carcinomas (HNSCC) remains poorly characterized. Here, we comprehensively analyzed the HNSCC single-cell transcriptomic dataset (GSE172577) and identified 5 subsets of myeloid-driven cells as TAMs using Seurat.

3.1.3 Polymers correspond to Grade F (130–155 °C) Polycarbonate (PC) is a common dielectric polymer and it has excellent thermal stability under the action of π bonds in benzene rings,69 which leads to Tg up to 150 °C. Due to the rigidity of the molecular chains, it is difficult to orient and crystallize, resulting in a low crystallinity. During the range of 25 °C to 125 °C (1 kHz), both the εr (~3) and tan δ (~0.1%) of PC exhibit strong independence to temperature.
