Published: January 2023

AbstractDamage to solid polymer electrolytes can lead to mechanical degradation, short circuits, or functional failures. Therefore, introducing a self‐healing function to solid polymer electrolytes is an ideal strategy to improve the safety and reliability of electrolyte systems. Herein, dynamic boronic ester‐based self‐healing polymer electrolytes (DB‐SHPEs) with excellent mechanical properties and interfacial stability are developed via a thermally initiated ring‐opening reaction between thiol and epoxy groups. The DB‐SHPEs containing boronic ester bonds can not only alter the topologies via boronic ester transesterification and exhibit good self‐healing capability but also enable homogeneous deposition of Li ions on the Li metal through the Lewis acid–base interactions between boron atoms and salt anions. Furthermore, the boronic ester bonds can endow the DB‐SHPE with reprocessability and recyclability taking advantage of associative transesterification reaction. More significantly, the Li/DB‐SHPE/Li symmetric cells exhibit a stable voltage plateau after cycling for 1200 h and the LiFePO4/DB‐SHPE/Li batteries present excellent cycling performance, suggesting that high‐performance self‐healing polymer electrolytes with multiple functions are promising materials for the next‐generation lithium metal batteries.

Published: January 2023

AbstractDual doping of boron (B) and nitrogen (N) provides an effective strategy to tailor chemical properties and electron distributions in the carbon plane, as well as customize the energy storage performance. Herein, a systematic theoretical and experimental study on rationally constructing coralloidal B, N dual‐doped carbon (BNC) nano‐bundles with abundant BN bonds for efficient Zn‐ion storage is presented. Compared with the single B or N doped sample and other dual‐doped B and N sites, the BN bond sites are found to boost the adsorption of Zn ions and enhance the electronic conductivity, which efficiently contribute to Zn‐ion storage. As expected, the optimized BNC nano‐bundles display greatly improved electrochemical performance, manifested by the high specific capacity of 204 mAh g−1 at 0.2 A g−1 and ultralong cycling stability for 40 000 cycles, outperforming most of the state‐of‐the‐art carbon cathodes. Moreover, a distinguished energy density of 178.7 Wh kg−1 and a high‐power density of 17.5 kW kg−1 are achieved with a constructed BNC//Zn device. This work not only provides critical insight for designing advanced carbon materials but also deepens the fundamental understanding of the governing mechanisms in dual‐doped carbon electrodes.

AbstractHigh‐performance elastomers are expected to possess excellent healing and recycling ability, damage resistance in conjunction with high strength and toughness. Herein, a dual dynamic crosslinking strategy is implemented by multiple hydrogen and disulfide bonds to obtain a novel amorphous and transparent polyurethane/nanocellulose elastomer with excellent self‐healing, self‐reinforcing and toughening performance. First, hydrogen bonds are introduced in TEMPO‐oxidized cellulose nanofibers (TCNF) by modification with 2‐ureido‐4[1H]‐pyrimidone (UTCNF), while disulfide bonds (SS) are introduced in the polyurethane (PU) main chain, leading to the formation of dual dynamic cross‐linking networks. The PU‐SS‐UTCNF elastomer can fully self‐heal within 4.0 h at 50 °C. Surprisingly, for the first time, the PU‐SS‐UTCNF elastomer also self‐strengthens and self‐toughens after multiple hot‐pressing, with tensile strength and toughness that increase by up to 401% and 257% compared to original elastomer samples, up to 50.0 MPa and 132.5 MJ m‐3. The self‐strength and self‐toughening effects are attributed to 1) reconstruction of dual dynamic networks that increase the cross‐linking degree during the multiple hot‐pressing processes; 2) multiple hydrogen bonds in the system are beneficial to the orientation of highly crystallized UTCNF, as a replacement of stress‐induced process in deformation under external tensile force.

Published: January 2023

AbstractMechanical robust hydrogels are ideal for applications in energy, environment, biomedicine, and structural engineering materials fields. However, high strength and high toughness are usually in conflict with each other, and simultaneously achieving both of them within a hydrogel has been challenging. Herein an organic‐inorganic synergistic toughening strategy is reported via in‐situ inorganic ionic polymerization of calcium phosphate oligomers within polymer composite networks composed of polyvinyl alcohol chains and aramid nanofibers. The composite hydrogels are provided with a prestress‐induced hierarchically fibrous structure through the assembly, which resulted in the mechanical strength and toughness up to 24.15 ± 1.12 MPa and 15.68 ± 1.78 MJ m−3, respectively, surpassing most toughened hydrogels. Through lamination and crosslinking, bulk hydrogels with controllable mechanical anisotropy and significant energy absorption/dissipation ability are produced. Moreover, the recycling and regeneration of the hydrogels are easily realized owing to the physically crosslinked network and acid‐induced dissolution of the inorganic units of the hydrogels, which lays a foundation for the sustainable large‐scale production and application of the hydrogels. This study provides an alternative approach for the development of mechanical robust and recyclable nanocomposite hydrogels for various applications including soft body armor, flexible electronics, soft robotics, etc.

Published: January 2023

AbstractConventional organic optoelectronic devices suffer from low carrier mobility limited by the static and dynamic disorder. Organic crystals with long‐range order can circumvent the effects of disorder and significantly improve the charge transport. While highly ordered organic crystals offer the desirable electronic coupling strength and charge transport, their integration into large‐area optoelectronic devices remains a challenge. Here, monolithic integrated triclinic crystal rubrene light‐emitting diodes (LEDs) are presented using epitaxial growth with functional additives being engineered into the films. Superior charge transport, excellent operational and long‐term stability in these light‐emitting devices are demonstrated. By comparing two rubrene‐based LEDs, one made from amorphous and one from crystalline rubrene layers, their exciton dynamics are estimated using comprehensive transient electroluminescence simulation. The crystalline LEDs show high triplet‐triplet annihilation (TTA) rate constant similar to TTA rate constant of triclinic single crystals determined by optical spectroscopy. At the same time, the crystalline phase enhances drastically the singlet‐fission and bimolecular annihilation rates, which reduces the overall performance of the LED compared to its amorphous counterpart. Finally, an outlook on the potential applications of rubrene and/or its derivatives crystalline films are provided for enhancing the performance of organic and hybrid optoelectronic devices.

AbstractExhibiting outstanding optoelectronic properties, antimony selenide (Sb2Se3) has attracted considerable interest and has been developed as a light absorber layer for thin‐film solar cells over the decade. However, current state‐of‐the‐art Sb2Se3 devices suffer from unsatisfactory “cliff‐like” band alignment and severe interface recombination loss, which deteriorates device performance. In this study, the heterojunction interface of an Sb2Se3 solar cell is improved by introducing effective aluminum (Al3+) cation into the CdS buffer layer. Then, the energy band alignment of Sb2Se3/CdS:Al heterojunction is modified from a “cliff‐like” structure to a “spike‐like” structure. Finally, heterojunction interface engineering suppresses recombination losses and strengthens carrier transport, resulting in a high efficiency of 8.41% for the substrate‐structured Sb2Se3 solar cell. This study proposes a facile strategy for interfacial treatment and elucidates the related carrier transport enhancement mechanism, paving a bright avenue to overcome the efficiency bottleneck of Sb2Se3 thin‐film solar cells.

AbstractThe theoretically high‐energy‐density lithium–sulfur batteries (LSBs) are seriously limited by the disadvantages including the shuttle effect of soluble lithium polysulfides (LiPSs) and the sluggish sulfur redox kinetics, especially for the most difficult solid–solid conversion of Li2S2 to Li2S. Herein, a multifunctional catalytic interlayer to improve the performance of LSBs is tried to introduce, in which Fe1–xS/Fe3C nanoparticles are embedded in the N/S dual‐doped carbon network (NSC) composed by nanosheets and nanotubes (the final product is named as FeSC@NSC). The well‐designed 3D NSC network endows the interlayer with a satisfactory LiPSs capture‐catalytic ability, thus ensuring fast redox reaction kinetics and suppressing LiPSs shuttling. The density functional theory calculations disclose the catalytic mechanisms that FeSC@NSC greatly improves the liquid–solid (LiPSs to Li2S2) conversion and unexpectedly the solid–solid (Li2S2 to Li2S) one. As a result, the LSBs based on the FeSC@NSC interlayer can achieve a high specific capacity of 1118 mAh g−1 at a current density of 0.2 C, and a relatively stable capacity of 415 mAh g−1 at a large current density of 2.0 C after 700 cycles as well as superior rate performance.

AbstractMonolayer MoS2 has attracted significant attention owing to its excellent performance as an n‐type semiconductor from the transition metal dichalcogenide (TMDC) family. It is however strongly desired to develop controllable synthesis methods for 2D p‐type MoS2, which is crucial for complementary logic applications but remains difficult. In this work, high‐quality NbS2–MoS2 lateral heterostructures are synthesized by one‐step metal–organic chemical vapor deposition (MOCVD) together with monolayer MoS2 substitutionally doped by Nb, resulting in a p‐type doped behavior. The heterojunction shows a p‐type transfer characteristic with a high on/off current ratio of ≈104, exceeding previously reported values. The band structure through the NbS2–MoS2 heterojunction is investigated by density functional theory (DFT) and quantum transport simulations. This work provides a scalable approach to synthesize substitutionally doped TMDC materials and provides an insight into the interface between 2D metals and semiconductors in lateral heterostructures, which is imperative for the development of next‐generation nanoelectronics and highly integrated devices.

Published: January 2023

AbstractIt is significant to monitor the different RNA granules dynamics and phase separation process inside cells under various stresses, for example, oxidative stress. The current small‐molecule RNA probes work well only in fixed cells and usually encounter problems such as insufficient stability and biocompatibility, and thus a specific RNA‐targeting fluorescent nanoprobe that can be used in the living cells is urgently desired. Here, the de novo design and microwave‐assisted synthesis of a novel RNA‐targeting, red‐emissive carbon dots (named as M‐CDs) are reported by choosing neutral red and levofloxacin as precursors. The as‐synthesized M‐CDs is water‐soluble with a high fluorescence quantum yield of 22.83% and can selectively bind to RNA resulting in an enhanced red fluorescence. More interestingly, such an RNA‐targeting, red‐emissive M‐CDs can be fast internalized into cells within 5 s and thus used for real‐time imaging the dynamic process of intracellular stress granules under oxidative stress, revealing some characteristics of granules that have not been identified by previously reported RNA and protein biomarkers. This research paves a new pathway for visualizing bulk RNA dynamics and studying phase‐separation behaviors in living cells by rational design of the fluorescent carbon dots in terms of structure and functionality.

Published: January 2023

AbstractDeveloping new anticounterfeit technologies with good robustness, high safety index, strong readability, and low cost is highly demanded but challenging. In recent years, anticounterfeiting labels by surface‐enhanced Raman spectroscopy (SERS) have drawn great attention due to the molecular encoding, highly accurate identification, large coding capacity, and so on. Focusing on several basic elements in SERS anticounterfeiting, the SERS anticounterfeiting labels’ structure, the fabrication strategies, and their performances are summarized and commented in detail based on three main categories of SERS labels (SERS spectra, SERS images, and SERS codes). Moreover, despite the great advances achieved till now, SERS labels for anticounterfeiting still suffer from some limitations. Thus, the current challenges and the perspective of the SERS labels in anticounterfeiting are also discussed, aiming to give a comprehensive understanding and some valid guidelines for the development of SERS labels in anticounterfeiting.
3D Printed Spin‐Decoupled Transmissive Metasurfaces Based on Versatile Broadband Cross‐Polarization Rotation Meta‐Atom

Published: January 2023

AbstractThis article proposes 3D printed broadband transmissive metasurfaces for spin‐decoupled wavefront shaping based on a versatile broadband cross‐polarization rotation meta‐atom. A meta‐atom combining broadband cross‐linear polarization dynamic phase and Pancharatnam–Berry (P–B) phase is demonstrated to realize spin‐decoupled beam shaping. The meta‐atom is built in an antenna‐circuit‐antenna fashion. Stacked patch antennas are used here as both the receiving and transmitting antennas because they can achieve wide bandwidth and good impedance matching to free space. By carefully selecting the phase delay lines’ path, the meta‐atom converts the x‐polarized or y‐polarized linear incident wave to its cross‐polarization with the co‐polarized components suppressed. The function also leads to the spin conversion for the circularly polarized incident wave. Thus, P–B phase‐shifting will be introduced when the meta‐atom is rotated. In addition, the transmission line provides the same dynamic phase delay for both left‐ and right‐hand circular polarization (LHCP and RHCP) incident waves. Then, combining the two different phase‐shifting methods, i.e., the P–B phase and dynamic phase, the LHCP and RHCP wavefront can be fully decoupled. Two different metasurfaces achieving spin‐decoupled anomalous refraction carrying orbital angular momentum (OAM) with different topological charges are simulated and experimentally verified for demonstration.

AbstractCadmium (Cd) is a high‐risk pathogenic toxin for hepatic diseases. Excessive mitophagy is a hallmark in Cd‐induced hepatotoxicity. However, the underlying mechanism remains obscure. Mitochondrial calcium uniporter (MCU) is a key regulator for mitochondrial and cellular homeostasis. Here, Cd exposure upregulated MCU expression and increased mitochondrial Ca2+ uptake are found. MCU inhibition through siRNA or by Ru360 significantly attenuates Cd‐induced excessive mitophagy, thereby rescues mitochondrial dysfunction and increases hepatocyte viability. Heterozygous MCU knockout mice exhibit improved liver function, ameliorated pathological damage, less mitochondrial fragmentation, and mitophagy after Cd exposure. Mechanistically, Cd upregulates MCU expression through phosphorylation activation of cAMP‐response element binding protein at Ser133(CREBS133) and subsequent binding of MCU promoter at the TGAGGTCT, ACGTCA, and CTCCGTGATGTA regions, leading to increased MCU gene transcription. The upregulated MCU intensively interacts with voltage‐dependent anion‐selective channel protein 1 (VDAC1), enhances its dimerization and ubiquitination, resulting in excessive mitophagy. This study reveals a novel mechanism, through which Cd upregulates MCU to enhance mitophagy and hepatotoxicity.

AbstractThe current power conversion efficiencies of laboratory‐sized organic solar cells (OSCs), based on the spin‐coating process with halogenated solvents, have exceeded 19%. Environmentally friendly printing is needed to bridge the gap between laboratory and industrialization by being compatible with roll‐to‐roll large‐area production. Here, the molecular design rules are revealed for enhancing the green printing potential of the state‐of‐the‐art photovoltaic martial systems by investigating the detailed structure formation dynamic and the key determining factors. By comparing two model systems based on D18:Y6 and D18:BTP‐eC9, it is found that disordered preaggregation in liquid state can result in over‐sized domains with reduced crystallinity and disordered molecular orientation, which significantly limits device performance. By systematically tuning the length of the inner alkyl side chains with multiple Y‐series materials, the authors demonstrate that molecular side‐chain engineering can effectively supress the detrimental disordered preaggregation in liquid state during environmentally friendly printing process, leading to enhanced crystallization with preferential faceon molecular orientation, more efficient exciton dissociation and charge carrier transport, and finally high upscaling potential. The work provides deeper insights into molecular engineering and structure formation dynamics toward environmentally friendly production of OSCs.

AbstractNickel–iron oxygen evolution catalysts have been under the spotlight as substitutes for precious metals, however, they rarely operate efficiently in practical industrial electrolyzers due to their moderate activity. Guided by density functional theory, the interaction of cation vacancies and dopants can manipulate d band centers, thus gaining near‐optimal binding energies of the oxygenated intermediates and ultralow potentials. This principle is implemented experimentally by catalysis operando variations synthesis, more specifically, in situ Mo leaching from high‐entropy Co, Mo co‐doped NiFe hydroxide precursors form Co dopant and cation vacancy coexistent NiFe oxyhydroxide. Operando electrochemical spectroscopy uncovers that dual‐cation‐defects promote the readier oxidation transition of metal sites, thus contributing to a low overpotential of 255 mV at 100 mA cm−2. Furthermore, dual‐regulated NiFe oxyhydroxide electrodes operate stably at 8 A  in practical industrial electrolyzers with ultralow energy consumption of ≈4.6 kWh m−3H2, verifying the feasibility of lab‐constructed novel catalysts towards industrialization.

AbstractAs a vital technology in portable electronic equipment, electric vehicle, and stationary energy storage, lithium‐based batteries are currently gaining widespread attention. However, when batteries are used more frequently, there are greater worries regarding their susceptibility to temperature, especially at low temperatures (LTs). In this review, the factors that lead to capacity loss in lithium‐based batteries at LT are analyzed and a summary of the most recent cutting‐edge approaches for improving LT kinetics is provided. In order to achieve satisfactory LT performance, electrode technology, interface chemistry, and electrolyte engineering must be taken into account during the cell design process. The recently revealed unique cryogenic storage mode and design concepts are also thoroughly introduced in this review, which is intended to motivate researchers in related domains. Finally, new insights, intriguing concepts, and workable solutions are proposed to promote the ongoing development of high‐performance cryogenic lithium batteries.
