“…Owing to the presence of rGO, both S-NiSe/HG and NiSe/rGO exhibit conductor properties without band gaps, indicating promising conduction loss (Figure c and Figure S16d). The DOS of C at the Fermi level increases for S-NiSe/HG, while the DOS of Ni and Se decreases, signifying more intense electron transition in defective S-NiSe/HG . Also, the total DOS at the Fermi level is higher for S-NiSe/HG (Figure d).…”

Exploring anticorrosion electromagnetic wave (EMW) absorbing materials in harsh conditions remains a challenge. Herein, S-NiSe/HG nanocomposites encapsulated in room-temperature self-healing polyurethane (S-NiSe/HG/SPU) were exploited as superior anticorrosion EMW absorbing materials. A dual-defect engineering collaborative Schottky interface construction endows S-NiSe/HG with a high vacancy concentration, abundant defects, and moderate conductivity. These structural merits synergistically balance dielectric loss by enhancing dipole-interface polarization loss and optimizing conduction loss. As a result, S-NiSe/HG demonstrates the optimal EMW absorption performance with a minimum reflection loss (RL min ) of −54.8 dB and an adequate absorption bandwidth (EAB) of 7.1 GHz. Besides, S-NiSe/HG/SPU combines the maze effect of S-NiSe/HG with the active repair capability of SPU, thereby providing long-term corrosion resistance for the Mg alloy. Even under corrosion for 10 days, S-NiSe/HG/SPU affords a low corrosion current density (1.3 × 10 −5 A) and high charge transfer resistance (3796 Ω cm 2 ). Overall, this work provides valuable insights for in-depth exploration of dielectric loss and development of multifunctional EMW-absorbing materials.

“…Photon upconversion, which can absorb low-energy photons, but emit high-energy photons, is regarded as an excellent nonlinear-optical phenomenon. [156] The processes of triplet-triplet annihilation (TTA)-related upconversion [157,158] and UNPs [159][160][161][162][163][164][165] are the two primary approaches toward upconverted CPL. Duan et al [113] reported the upconverted CPL relying on the TTA process in 2017.…”

[161,164,[169][170][171] Duan et al [172] designed a chiral emissive system by integrating UNPs and perovskites into the cholesteric LC and successfully demonstrated an enhanced upconverted CPL dependent on the radiativeenergy transfer (RET) from UNPs to the CsPbBr 3 perovskite nanocrystals. The g lum of the upconverted CPL could be amplified to a significantly high value of 1.1 by adjusting the emission peak of the CsPbBr 3 perovskite nanocrystals at the center of the PBG in cholesteric LCs.…”

Circularly polarized luminescent (CPL) materials have received significant attention in the field of fundamental science recently. These materials offer substantial advancement of technological applications, such as optical data storage, displays, and quantum communication. Various strategies have been proposed in self‐assembled materials consisting of inorganic, organic, and hybrid systems, particularly in the chiral orientationally ordered soft matter systems (e.g., chiral liquid crystals (LCs) and LC polymers). However, developing scientific approaches to achieve the pronounced and steerable circularly polarized light emission remains challenging. Herein, we present a comprehensive review on the recent development of CPL materials based on chiral LCs, including thermotropic LCs (cholesteric LCs and bent‐core LCs), lyotropic LCs (nanocellulose LCs and polyacetylene‐based LCs), and LC polymers (cholesteric LC‐based polymers, helical nanofibers, and helical network). In addition, the fundamental mechanisms, design principles, and potential applications based on these chiral LCs and LC polymers in soft matter systems are systematically reviewed. This review summarizes with a prospect on the latent challenges, which can strengthen our understanding of the basic principles of CPL in chiral orientationally ordered soft matter systems and provide a new insight into the progress in several fields, such as chemistry, materials science, optics, electronics, and biology.

“…[ 4–6 ] As the state‐of‐the‐art energy storage devices, lithium‐ion batteries (LIBs) have been applied widely during the past decades, especially in portable electronic devices. [ 7–10 ] Unfortunately, the scarcity of lithium metal resources and the prohibitively expensive cost, have arisen some concerns of using LIBs in the large‐scale energy storage devices. [ 11–15 ] In such situations, aluminum‐ion batteries (AIBs) have entered researchers’ spotlight because of abundant reserves of aluminum metal (8.2 wt% in the Earth's crust), which leads to a low cost (1.9 USD kg –1 ), and it can deliver an ultrahigh volumetric capacity (8046 mAh cm –3 ) and gravimetric capacity (2980 mAh g –1 ) benefiting from three electrons state of Al 3+ .…”

Aluminum is the most abundant metal element in the Earth's crust, thus developing the rechargeable aluminum‐ion batteries (AIBs) provides an ideal opportunity to realize cells with pleasing energy‐to‐price ratios. However, the further development of AIBs is plagued by the scarcity of suitable positive electrode materials. Here, for the first time, a tin‐based alloy positive electrode material for AIBs, Co3Sn2 wrapped with graphene oxide (Co3Sn2@GO composite) is well‐designed and investigated to understand the aluminum storage behavior. A series of experimental measurements and theoretical calculations results reveal that a novel “bimetallic activated center alloying reaction” aluminum storage mechanism is occurred on the prepared Co3Sn2 positive electrode. The reversible alloying/de‐alloying process in AlCl3/[EMIm]Cl ionic liquid, where both Co and Sn in Co3Sn2 alloys react electrochemically with Al3+ to form AlxSn and AlyCo is first put forward. This study delineates new insights on the aluminum storage mechanism, which may guide to ultimately exploit the energy benefits of “bimetallic activated center alloying redox”.
