AbstractThis article reviews the research progress in the intercalation compounds for cathode materials for supercapacitors. Typical methods to prepare various intercalation compounds with different nanostructures are summarized. More specifically, the approaches can be subdivided into physical routes such as sonication and microwaves, and chemical routes such as hydrothermal, sol-gel and template methods. The most recent work on nanostructured intercalation compounds including LiCoO2, LiMn2O4, Li[Ni1/3Co1/3Mn1/3]O2, Li1+xV3O8, NaxMnO2, and KxMnO2 is mainly focused including their preparation and electrochemical performance, and new trends in nanomaterials development for supercapacitors are pointed out.

Lithium-ion batteries have attracted widespread attention as new energy storage materials, and electrode materials, especially cathode materials, are the main factors affecting the electrochemical performance of lithium-ion batteries, and they also determine the cost of preparing lithium-ion batteries. In recent years, there have been a lot of researches on the selection and modification of cathode materials based on lithium-ion batteries to continuously optimize the electrochemical performance of lithium-ion batteries. This article introduces the research progress of cathode materials for lithium ion batteries, including three types of cathode materials (layer oxide, spinel oxide, polyanionic compound) and three modification methods (doping modification, surface coating modification, nano modification method), and prospects for the future development of lithium ion battery cathode materials.

Pt-based alloys are being developed for high-temperature applications with the aim of replacing some of the currently used Ni-based superalloys (NBSAs) and benchmark alloy, PM2000. The Pt-based superalloys have a similar structure to the NBSAs and can potentially be used at higher temperatures and in more aggressive environments because Pt is more chemically inert and has a higher melting point. In this paper, the recent progress in research and development of Pt-based superalloys is overviewed. Firstly, the composition optimization and structural design of Pt-base superalloys are introduced. The structural characteristics, mechanical properties, oxidation resistance and corrosion behavior of Pt-Al ternary, quaternary and multiple superalloys are summarized. Finally, directions for further research and application of Pt-base superalloys are analyzed and prospected.

And Performance

The metamaterial is a composite material with reasonable design. Its effective material parameters exceed the effective parameters of component materials, which shows unique properties. The concept of metamaterials has been put forward since 1960s. Nowadays, it almost involves all possible aspects of solids, from the fields of electromagnetism and optics, and mechanics and acoustics to thermology, information and other fields, and there are many research results reported, such as linear and nonlinear, reciprocal and non-reciprocal, steady and unsteady state, active and passive and so on. In this review, we start from the basics, mainly discussing the basic scope and performance characteristics of the metamaterials in optics, electromagnetism, acoustics, thermology and other emerging fields, summarizing the development process and the latest progress of theoretical design as well as experimental practices, making expectations and prospects for the future targets.
