“…The structure presented a very low transmittance of 10% when no strain was applied while the transmittance was enhanced to 90% as the strain was raised to 400%. In addition, metallic glass [ 100 ] is another alternative for the delamination buckling‐based MC window. The semitransparent metallic glass film was deposited on pre‐stretched PDMS substrate.…”

the building envelope, which mainly consists of transparent and opaque components. For transparent components (e.g., window), the STRMMs should have high transparency of visible light (0.38-0.76 µm) under both hot and cold ambient conditions to guarantee natural lighting. Nearinfrared (NIR) light (0.77-2.5 µm), which accounts for 52% of solar heat, [9] should be reflected in summer for cooling purpose but be transmitted into room in winter to induce solar heat gains. For opaque components (e.g., wall), the STRMMs should have high reflectance of both visible and NIR lights in summer but low reflectance of both lights in winter. Meanwhile, as both transparent and opaque components continuously emit thermal radiation into the outdoor ambient, the STRMMs should have low infrared thermal emissivity in winter to suppress radiative heat loss but high infrared thermal emissivity in summer to accelerate radiative heat dissipation. Figure 1b shows the ideal optical properties of STRMMs applied on transparent and opaque components in both heating and cooling modes. Existing reviews mainly focused on the daytime radiative cooling materials with fixed solar reflectance and thermal emissivity, [10][11][12] which only helps reduce building cooling loads in summer but inevitably increases building heating loads in winter, leading to limited building energy savings. Recently, owing to the rapid development of material science, the STRMMs have been widely explored, which can dynamically modulate the optical properties under external triggers (e.g., thermo and electrical) to accommodate the heating/cooling needs of building in different seasons, showing improved building energy-saving potentials. [13][14][15][16][17] Although there are reviews reporting the materials with modulating optical properties, [15,18] they merely focused on either solar or thermal radiation modulation, which provide limited or even negative building energy savings, which may mislead the researchers to design low energy-efficient materials in practice. For instance, the thermochromic (TC) window can achieve low solar transmittance in hot season but high solar transmittance in cold season. [13,19] Nonetheless, it maintains high thermal emissivity (above 90%) in both seasons. This would accelerate heat loss of building in cold season, and result in limited energy savings. The vanadium dioxide (VO 2 )-based Fabry-Perot (FP) resonator can achieve low thermal emissivity in cold season but high thermal emissivity in hot season, while it maintains constant solar absorptance (25%) in both seasons. This would induce much more solar heating than the conventional cooling materials with smaller solar absorptance (10%), resulting in Regulation of solar and thermal radiation of building envelope shows huge energy-saving potentials. Existing reviews mainly focus on the materials with fixed solar and thermal optical properties. Although there are reviews reporting the materials with modulated optical properties (e.g., radiative cooling materials with modulating thermal emi...

Amorphous alloys have attracted great attention due to their distinctive properties derived from unique packing structures. Recently, significant advances have been achieved for the understanding of structural characteristics and functional applications of amorphous alloys. Herein, an overview of the state of art of structure studies, accounting for the characteristics of amorphous alloys, are presented, and recent progresses in the functional applications of amorphous alloys are highlighted. The various structural models for the short‐range order, medium‐range order, and long‐range topological order for amorphous alloys are introduced. The functional applications in electrochemistry, mechanism, magnetism, optics, and biomedical engineering are presented in detail. The fundamental understanding of the correlations between structures and properties in amorphous alloys is discussed.

Metallic glasses (MGs), which are also known as amorphous metals, are formed by quenching the melts at a super high cooling rate (e. g. 106 K/s) to avoid crystallization. Compared with ordinary metals, there is no long‐range translational order and crystalline defects in MGs. Benefitting from this unique structural characteristic, MGs show many superior mechanical, physical and chemical properties and thus have been attracting intensive attentions in applications as structural materials. The investigations on the functional properties of MGs are still at the early stage, but immense potential in electrochemically functional applications has been demonstrated in recent years. In this Minireview, we aim to present an overview of the functional properties of this class of novel metallic glassy catalysts and some achievements obtained so far. We mainly focus on the applications of MGs in various electrochemical applications, like hydrogen evolution reaction and oxygen evolution reaction as well as fuel cells. The strategies for optimizing the performance of these amorphous catalysts are discussed as well, including high‐throughput screening and nano‐engineering. In the absence of crystalline ordering, the atomic‐scale structural mechanism of MGs in electrocatalysis may be unique and will be explored. Finally, we also give perspectives on how to design novel and superior electrocatalysts for future electrocatalysis applications.
