“…Some categories of metastable or amorphous materials are sensitive to electron beam irradiation or exposure to air, such as electrodes in LIBs, chiral materials with ligands, or amorphous metal compounds [ 82–85 ]. To fully characterize the aforementioned materials, low-dose transmission electron microscopy (TEM) and cryogenic electron microscopy (cryo-EM) are usually applied to expose materials to less irradiation to avoid the knocking out of atoms from the surface [ 86 , 87 ], preventing phase transformation or damage to the target materials during characterization [ 88 , 89 ].…”

Structural engineering of metastable nanomaterials with abundant defects has attracted extensive attention in energy-related fields. High-temperature shock (HTS) technique, as a rapid-developing and advanced synthesis strategy, offers significant potential for the rational design and fabrication of high-quality nanocatalysts in an ultrafast, scalable, controllable, and eco-friendly way. In this review, we provide an overview of various metastable micro-/nano- materials synthesized via HTS, including single metallic and bimetallic nanostructures, high entropy alloys, metal compounds (e.g. metal oxides), and carbon nanomaterials. Note that HTS provide a new research dimension for nanostructure, i.e. kinetic modulation. Furthermore, we summarize the application of HTS in structural engineering of 2D materials as supporting films for transmission electron microscopy (TEM) grids, which is vital for the direct imaging of metastable materials. Finally, we discuss the potential future applications of high-throughput and liquid-phase HTS strategies for non-equilibrium micro/nano-manufacturing beyond energy-related fields. It is believed that this emerging research field will bring new opportunities to the development of nanoscience and nanotechnology in both fundamental and practical aspects.

“…The wet-chemistry method is a widely employed technique for generating chiral structures. [120] Nevertheless, this approach often leads to the production of racemic mixtures without any external bias for left-right asymmetry, thereby necessitating the presentation of chiral biases. [64] A prevalent method involves the addition of homochiral ligands, which serve as stabilizers and can effectively inhibit the nucleation and growth of products possessing opposite chirality.…”

Chirality represents a fundamental characteristic inherent in nature, playing a pivotal role in the emergence of homochirality and the origin of life. While the principles of chirality in organic chemistry are well‐documented, the exploration of chirality within inorganic crystal structures continues to evolve. This ongoing development is primarily due to the diverse nature of crystal/amorphous structures in inorganic materials, along with the intricate symmetrical and asymmetrical relationships in the geometry of their constituent atoms. In this review, we commence with a summary of the foundational concept of chirality in molecules and solid states matters. This is followed by an introduction of structural chirality and electronic chirality in three‐dimensional and two‐dimensional inorganic materials. The construction of chirality in inorganic materials is classified into physical photolithography, wet‐chemistry method, self‐assembly, and chiral imprinting. Highlighting the significance of this field, we also summarize the research progress of chiral inorganic materials for applications in optical activity, enantiomeric recognition and chiral sensing, selective adsorption and enantioselective separation, asymmetric synthesis and catalysis, and chirality‐induced spin polarization. This review aims to provide a reference for ongoing research in chiral inorganic materials and potentially stimulate innovative strategies and novel applications in the realm of chirality.

“…In recent years, spurred by the rapid developments of nanotechnology, researchers have delved into a range of plasmonic and photonic strategies to achieve CD responses, including metal helices [3][4][5][6], chiral metal naonoparticles [7][8][9][10], achiral metal nanostructures [11][12][13][14][15], as well as dielectric chiral assemblies and metasurfaces [16][17][18]. The CD response of nanostructures have potential applications in many fields of chiral catalysis [19], chiral discrimination, chiral sensing, etc [20][21][22]. As mentioned above, metal nanostructures can be designed to obtain strong CD signal owing to the plasmon resonance [3,23].…”

Circular dichroism (CD) spectra play a crucial role in recognition, separation and detection of chiral molecules. Due to the inherent weak CD response of natural chiral molecules, researchers have endeavored to enhance CD signals through various artificial nanostructures. In this study, combining the advantages of both the dielectric and metal materials, we propose a hybrid dielectric-metal nanostructure consisting of a chiral Si nanorod dimer coupled with a symmetric Au cylinder to achieve robust CD responses. Owing to the plasmon resonance of the Au cylinder, the scattering- and absorption-CD of the hybrid system have been enhanced, which result in the enhanced extinction CD response. Furthermore, the distributions of electric field, magnetic field and displacement current density of both the Si dimer and hybrid nanostructure have been meticulously crafted to elucidate the physical mechanisms underlying amplified CD signals. The synergistic coupling between the magnetic fields of dielectric materials and the electric fields of the Au cylinder leads to an increase in the electric field strength and the asymmetry of near-field distributions. Additionally, spatial overlaps between electric and magnetic fields occur. These factors contribute to the enhanced chiral response of the hybrid system. Meanwhile, the CD signal can be flexibly tuned by adjusting the size of the Au cylinder and Si nanorods. This design offers a versatile approach to enhancing the chiral response of dielectric nanostructures.
