Hot-injection method is widely used in the synthesis of colloidal nanocrystals. The conventional hot-injection process suffers from severe yield loss in the mass production of monodisperse colloidal nanocrystals. The time-consuming standard cooling procedure via long-distance thermal transport results in continuous nanocrystal growth, leading to broad size distribution and yield loss. In this paper, we employed the direct injection of low-temperature solvent as an additional quenching agent. CsPbBr 3 colloidal nanocrystals with highly efficient narrow-band green emission and outstanding stability were obtained. The solvent fast quenching process creates a large instant undercooling, which could sharply increase the nucleation rate throughout the whole solution, leading to the high-yield formation of nanocrystals. Meanwhile, it inhibits the subsequent nanocrystal growth and thus could greatly improve the size uniformity and crystal quality. This mild quenching hot-injection method can be used not only for the large-scale preparation of perovskite colloidal nanocrystals but also for the preparation of other types of colloidal nanocrystals. In addition, the perovskite nanocrystal (PNC) array with a resolution of over 1300 pixels per inch was achieved via a common photolithography method. It also provides the possibility for commercial application in future full-color high-definition PNC displays.

Nanostructuring is a commonly employed method of obtaining superior mechanical properties in metals and alloys. Compared to conventional polycrystalline counterparts, nanostructuring can provide remarkable improvements in yield strength, toughness, fatigue life, corrosion resistance, and hardness, which is attributed to the nano grain size. In this review paper, the current state-of-the-art of synthesis methods of nanocrystalline (NC) materials such as rapid solidification, chemical precipitation, chemical vapor deposition, and mechanical alloying, including high-energy ball milling (HEBM) and cryomilling was elucidated. More specifically, the effect of various process parameters on mechanical properties and microstructural features were explained for a broad range of engineering materials. This study also explains the mechanism of grain strengthening using the Hall-Petch relation and illustrates the effects of post-processing on the grain size and subsequently their properties. This review also reports the applications, challenges, and future scope for the NC materials.
