Energy storage/conversion has become crucial not only to meet the present energy demand but also more importantly to sustain the modern society. Particularly, electrical energy storage is critical not only to support electronic, vehicular and load-levelling applications but also to efficiently commercialize renewable energy resources such as solar and wind. While Li-ion batteries are being intensely researched for electric vehicle applications, there is a pressing need to seek for new battery chemistries aimed at stationary storage systems. In this aspect, Zn-ion batteries offer a viable option to be utilized for high energy and power density applications since every intercalated Zn-ion yields a concurrent charge transfer of two electrons and thereby high theoretical capacities can be realized. Furthermore, the simplicity of fabrication under open-air conditions combined with the abundant and less toxic zinc element makes aqueous Zn-ion batteries one of the most economical, safe and green energy storage technologies with prospective use for stationary grid storage applications. Also, Zn-ion batteries are very safe for next-generation technologies based on flexible, roll-up, wearable implantable devices the portable electronics market. Following this advantages, a wide range of approaches and materials, namely, cathodes, anodes and electrolytes have been investigated for Zn-ion batteries applications to date. Herein, we review the progresses and major advancements related to aqueous. Zn-ion batteries, facilitating energy storage/conversion via $Zn^{2+}$ (de)intercalation mechanism.

Technologies for lithium secondary batteries are now increasingly expanding to simultaneously improve the safety and higher energy and power densities of large-scale battery systems, such as electric vehicles and smart-grid energy storage systems. Next-generation lithium batteries, such as lithium-sulfur (Li-S) and lithium-air (Li-O₂) batteries by adopting solid electrolytes and lithium metal anode, can be a solution for the requirements. In this analysis of battery technology trends, solid electrolytes, including polymer (organic), inorganic (oxides and sulfides), and their hybrid (composite) are focused to describe the electrochemical performance achievable by adopting optimal components and discussing the interfacial behaviors that occurred by the contact of different ingredients for safe and high-energy lithium secondary battery systems. As next-generation rechargeable lithium batteries, Li-S and Li-O₂ battery systems are briefly discussed coupling with the possible use of solid electrolytes. In addition, Electronics and Telecommunications Research Institutes achievements in the field of solid electrolytes for lithium rechargeable batteries are finally introduced.

최근 DRAM 기반의 메인 메모리 기술 발전이 한계에 봉착함에 따라 컴퓨터 시스템의 진보에도 어려움이 발생하고 있다. 이를 개선하기 위해 집적도가 높고 비휘발성을 갖는 차세대 메모리 기술이 등장하고 있으나 이들은 쓰기 속도가 느리거나 쓰기 횟수에 제한이 있는 등, 메인 메모리로 사용하기에는 아직 무리가 있다. 본 논문에서는 여러 차세대 메모리 기술들의 장점들을 조합하여 활용하는 하이브리드 메인 메모리 시스템, 즉 HyMN을 제안한다. HyMN은 차세대 메모리 기술을 쓰기적합램과 읽기적합램으로 분류하여 메인 메모리 시스템을 구성함으로써, 내구성이 양호하고, 고용량화가 용이하며, 비휘발성을 활용할 수 있는 시스템을 구현한다. 본 논문에서는 또한, 쓰기적합램이 어느 정도의 크기로 구성되어야 하는지를 보이고 정전 시 손실에 대한 복구비용이 없거나 미미한 HyMN이 일상적으로 프로세스를 실행할 때 실행 시간 성능이 DRAM으로만 구성된 시스템에 비하여 유사함을 검증한다.

The Cyber-Physical System (CPS) is a term describing a broad range of complex, multi-disciplinary, physically-aware next generation engineered system that integrates embedded computing technologies (cyber part) into the physical world. In order to define and understand CPS more precisely, this article presents a detailed survey of the related work, discussing the origin of CPS, the relations to other research fields, prevalent concepts, and practical applications. Further, this article enumerates an extensive set of technical challenges and uses specific applications to elaborate and provide insight into each specific concept. CPS is a very broad research area and therefore has diverse applications spanning different scales. Additionally, the next generation technologies are expected to play an important role on CPS research. All of CPS applications need to be designed considering the cutting-edge technologies, necessary system-level requirements, and overall impact on the real world.
