场限制环的安全环距设计原理

场限制环作为一种可与许多器件工艺相容的ＰＮ结终端得到了广泛应用。存在的一个问题是其效果随结构参数有过分敏感的变化。文中认为：作为设计指导思想的最佳环距原则是加重这一敏感性的重要原因。作为改进，提出了新的安全环距设计原则。按安全环距原则设计，除可明显缓解终端效果随结构参数敏感变化的问题外，还可有效地提高在同样结构和工艺条件下所制成器件的额定电压。

Electrocapacitive Deionization: Mechanisms,Electrodes, and Cell Designs

Capacitive deionization (CDI) is an emerging water desalination technology for removing different ionic species from water, which is based on electric charge compensation by these charged species. CDI is becoming popular because it is more energy-efficient and cost-effective than other technologies, such as reverse osmosis and distillation, specifically in dealing with brackish water having low or moderate salt concentrations. Over the past decade, the CDI research field has witnessed significant advances in the used electrode materials, cell architectures, and associated mechanisms for desalination applications. This review article first discusses ion storage/removal mechanisms in carbon and Faradaic materials aided by advanced in situ analysis techniques and computations. It then summarizes research progress toward electrode materials in terms of structure, surface chemistry, and composition. More still, it discusses CDI cell architectures by highlighting their different cell design concepts. Finally, current challenges and future research directions are summarized to provide guidelines for future CDI research.

Superelastic Carbon Aerogels: An Emerging Material for Advanced Thermal Protection in Extreme Environments

Carbon aerogels (CAs) are desirable for thermal protection in aerospace because of their lightweight and high-temperature insulation characteristic; however, their intrinsic brittleness and flaw sensitivity easily trigger catastrophic failure when resisting high-frequency thermal shocks or complex mechanical stresses. Compression is the predominant load applied on aerogels by aerodynamic pressure and pre-tightening force; therefore, the structural elasticity and exceptional capability to keep thermal performance under impact stress are crucial in deciding the actual availability of aerogels. This review presents the recent progress in newly resilient CAs for thermal protection, focusing on reliable structural stability, thermal stability, and thermal superinsulation property. The influence law of microstructures on heat transfer behaviors is first investigated, followed by construction strategies for adiabatic CAs, emphasizing the recoverable deformability resulting from increased continuity of building blocks from 0D nanoparticles to 1D nanofibers/nanotubes and then to 2D nanosheets. Moreover, the optimization of thermal stability in high-temperature aerobic environments and thermal insulation performance are discussed. Finally, it raises current challenges and further opportunities for CAs toward better properties and brighter prospects.
