“…In addition, the lattice distortion and the interaction between atoms also have a significant mitigation effect on the co-diffusion of atoms in RHEAs. Therefore, at high temperatures, RHEAs are not prone to produce phase transformation, and these can also have higher high-temperature strength [79,80]. From the mechanical point of view, these characteristics are the key mechanism to determine whether high-temperature alloy materials can be applied in a hightemperature field.…”

In the past decade, multi-principal element high-entropy alloys (referred to as high-entropy alloys, HEAs) are an emerging alloy material, which has been developed rapidly and has become a research hotspot in the field of metal materials. It breaks the alloy design concept of one or two principal elements in traditional alloys. It is composed of five or more principal elements, and the atomic percentage (at.%) of each element is greater than 5% but not more than 35%. The high-entropy effect caused by the increase of alloy principal elements makes the crystals easy form body-centered cubic or face-centered cubic structures, and may be accompanied by intergranular compounds and nanocrystals, to achieve solid solution strengthening, precipitation strengthening, and dispersion strengthening. The optimized design of alloy composition can make HEAs exhibit much better than traditional alloys such as high-strength steel, stainless steel, copper-nickel alloy, and nickel-based superalloy in terms of high strength, high hardness, high-temperature oxidation resistance, and corrosion resistance. At present, refractory high-entropy alloys (RHEAs) containing high-melting refractory metal elements have excellent room temperature and high-temperature properties, and their potential high-temperature application value has attracted widespread attention in the high-temperature field. This article reviews the research status and preparation methods of RHEAs and analyzes the microstructure in each system and then summarizes the various properties of RHEAs, including high strength, wear resistance, high-temperature oxidation resistance, corrosion resistance, etc., and the common property tuning methods of RHEAs are explained, and the existing main strengthening and toughening mechanisms of RHEAs are revealed. This knowledge will help the on-demand design of RHEAs, which is a crucial trend in future development. Finally, the development and application prospects of RHEAs are prospected to guide future research.

“…The size and shape of nanomaterials have a significant impact on their performance, and different morphologies may have distinct applications. The known conventional synthesis methods are usually classified into 'bottom-up' and 'top-down' methods, which broadly include hydrothermal methods [5][6][7][8], vapor deposition [9][10][11][12], pulsed laser methods [13][14][15][16], liquid phase separation [17][18][19][20] methods, etc, covering various physical and chemical methods. Figure 1 shows a scheme of the synthesis method for different selenium nanomaterials.…”

Over the past few decades, single-element semiconductors have received a great deal of attention due to their unique light-sensitive and heat-sensitive properties, which are of great application and research significance. As one promising material, selenium, being a typical semiconductor, has attracted significant attention from researchers due to its unique properties including high optical conductivity, anisotropic, thermal conductivity, and so on. To promote the application of selenium nanomaterials in various fields, numerous studies over the past few decades have successfully synthesized selenium nanomaterials in various morphologies using a wide range of physical and chemical methods. In this paper, we review and summarise the different methods of synthesis of various morphologies of selenium nanomaterials and discuss the applications of different nanostructures of selenium nanomaterials in optoelectronic devices, chemical sensors, and biomedical applications. Finally, we discuss possible challenges for selenium nanodevices and provide an outlook on the future applications of selenium nanomaterials.

High entropy alloys have been proved to be potential candidate materials in the biomedical field due to their balanced mechanical properties and excellent biocompatibility. The effects of atomic ratios on the as-cast microstructural evolution, mechanical properties, and electrochemical property of TiZrTaNbSn high entropy alloys were studied systematically. The crystal structure of TiZrTaNbSn high entropy alloys is single BCC phase, and the microstructural evolution is based on atomic ratio. The dendric structure, peritectic structure, pseudo eutectic and equiaxed grain, which are associated with element segregation, can be obtained by non-equal atomic ratio. Ti30Zr20Ta20Nb20Sn10 alloy demonstrates a high compressive strength and fracture strain, which are 2,571.8 MPa and 12%, respectively, and the fracture behavior is quasi-cleavage faults. The Ti45Zr35Ta5Nb5Sn10, Ti30Zr20Ta20Nb20Sn10 and Ti35Zr25Ta15Nb15Sn10 alloys show excellent corrosion resistance according to Nyquist diagram, polarization curves and corrosion morphology. Compared with TiZrTaNbSn alloy, the corrosion rate of Ti45Zr35Ta5Nb5Sn10 alloy increases by about 98.9%. It can be concluded that non-equal atomic ratios are effective for microstructure control and performance optimization.
