Published: September 2024

AbstractChiral carbon dots (CDs) with circularly polarized luminescence (CPL) are one of the most dynamic areas of modern science. However, the design, preparation, and ambiguity mechanism of solid‐state CPL‐active CDs remains a formidable challenge. Herein, for the first time, CDs with customized chiroptical activities in the solid state, especially CPL, are transcribed from chiral metal–organic framework (CMOFs) via a bottle‐around‐ship strategy. Within these CMOFs⊃CDs assemblies, CDs inherited the chirality of the host CMOFs through host–guest interactions, which is revealed by density functional theory (DFT) simulations and experimental results, and amplified the luminescence dissymmetry factor (glum) by effective artificial chiral light‐harvesting systems. Impressively, CMOFs⊃CDs in pairs generated color‐tunable CPL and white CPL with chromaticity coordinates of (0.32, 0.32). Furthermore, benefiting from excellent processability, as luminescent coatings and 3D printing inks, a white circularly polarized light‐emitting diode, and an extended 3D model “light bulb” featuring white CPL are successfully fabricated, respectively. This strategy paves a new avenue for the synthesis and advanced application of solid‐state CPL‐active CDs‐based materials.

AbstractAchieving emission peaks in the near‐infrared II regions (NIR II) and tunable near‐infrared (NIR) emission is still a huge challenge in the development of NIR phosphors. Here, a series of LiSc1‐yGayW2O8:Cr3+ phosphors are reported based on crystal engineering, whose luminescence can be tuned from NIR‐II to NIR I. LiScW2O8:Cr3+ possesses an ultra‐wide emission in the range of 850–1400 nm with peak at 1069 nm and a full width at half maximum (FWHM) of 225 nm and the main emission light is located in the NIR‐II region. Introducing Ga3+ into LiScW2O8:Cr3+ to form LiSc1‐yGayW2O8:Cr3+, the emission spectrum is blueshifted, which better aligns with the characteristic absorption lines of most functional groups. Additionally, the intensity of emission and thermal stability are also improved. The NIR phosphor‐converted light‐emitting diodes (pc‐LED) device is prepared by using the optimized LiSc0.5Ga0.5W2O8:0.12Cr3+ phosphor and green chip, and different characteristic absorptions are detected by measuring the NIR absorption of water and ethanol with the prepared pc‐LED as a radiation source. These results indicate that the ultra‐wide near‐infrared luminescence of LiSc1‐yGayW2O8:xCr3+ holds potential for applications in non‐destructive analysis.

AbstractSmart materials with circularly polarized luminescence (CPL) tunable ability show great potential for advanced information storage and encryption. While an effective integration of high photoluminescence quantum yield (PLQY) and facile regulation of CPL property in thin films are of great significance, it is challenging due to the scarcity of suitable materials and complexity of systems. Herein, a novel acid‐responsive CPL tunable molecule is designed by combining an aggregation‐induced emission (AIE) component (TPE), an acid‐responsive luminophore (Rhodol), and a chiral aniline. Benefitting by the “AIE” effect of TPE and acid‐sensitive nature of Rhodol, the acidified molecule (S‐Rhodol‐TPE) exhibits a high PLQY even when doped in the polymer substrate at high concentrations. In addition, due to the fluorescence resonance energy transfer (FRET) process between TPE and Rhodol, the emission color of S‐Rhodol‐TPE can be easily regulated by the doped ratio and acidified degree of S‐Rhodol‐TPE in the polymer film. This work exhibits a unique approach to achieving smart CPL‐tunable films with high PLQYs and multiple emission color‐regulation properties, which can undoubtedly facilitate the progress of CPL tunable materials.

Authors: Barnett Chloe , Eddy Kaitlyn , Rauk Phillip N. , Lewter Jill 
Published: September 2024

ABSTRACTTalipes equinovarus, also called clubfoot, is a relatively common congenital defect affecting approximately one in every 1000 live births. Most cases of clubfoot are expected to be idiopathic and unrelated to an underlying genetic syndrome. In approximately 20% of cases, a clear genetic etiology is identified. Here we present two cases of bilateral clubfoot identified via fetal ultrasound in the first trimester associated with osteogenesis imperfecta diagnosed in the second trimester. Both fetuses presented with multiple fractures and were identified to have loss‐of‐function variants in COL1A1. An association between clubfeet in the first trimester and osteogenesis imperfecta has not been previously reported to the best of our knowledge, which leads to unique opportunities for prompt diagnosis, genetic counseling and testing, and appropriate management.

AbstractGlycopeptides derived from the glycoprotein mucin‐1 (MUC1) have shown potential as tumor‐associated antigens for cancer vaccine development. However, their low immunogenicity and non‐selective conjugation to carriers present significant challenges for the clinical efficacy of MUC1‐based vaccines. Here, we introduce a novel vaccine candidate based on a structure‐guided design of an artificial antigen derived from MUC1 glycopeptide. This engineered antigen contains two non‐natural amino acids and has an α‐S‐glycosidic bond, where sulfur replaces the conventional oxygen atom linking the peptide backbone to the sugar N‐acetylgalactosamine. The glycopeptide is then specifically conjugated to the immunogenic protein carrier CRM197 (Cross‐Reactive Material 197), a protein approved for human use. Conjugation involves selective reduction and re‐bridging of a disulfide in CRM197, allowing the attachment of a single copy of MUC1. This strategy results in a chemically defined vaccine while maintaining both the structural integrity and immunogenicity of the protein carrier. The vaccine elicits a robust Th1‐like immune response in mice and generates antibodies capable of recognizing human cancer cells expressing tumor‐associated MUC1. When tested in mouse models of colon adenocarcinoma and pancreatic cancer, the vaccine is effective both as a prophylactic and therapeutic use, significantly delaying tumor growth. In therapeutic applications, improved outcomes were observed when the vaccine was combined with an anti‐programmed cell death protein 1 (anti‐PD‐1) checkpoint inhibitor. Our strategy reduces batch‐to‐batch variability and enhances both immunogenicity and therapeutic potential. This site‐specific approach disputes a prevailing dogma where glycoconjugate vaccines require multivalent display of antigens.

AbstractTopological defects are inevitable existence in carbon‐based frameworks, but their intrinsic electrocatalytic activity and mechanism remain under‐explored. Herein, the hydrogen evolution reaction (HER) of pentagonal carbon‐rings is probed by constructing pentagonal ring‐rich carbon (PRC), with optimized electronic structures and higher HER activity relative to common hexagonal carbon (HC). Furthermore, to improve the reactivity, we couple Ru clusters with PRC (Ru@PRC) through p‐d orbital hybridization between C and Ru atoms, which drives a shortcut transfer of electrons from Ru clusters to pentagonal rings. The electron‐deficient Ru species leads to a notable negative shift in d‐band centers of Ru and weakens their binding strength with hydrogen intermediates, thus enhancing the HER activity in different pH media. Especially, at a current density of 10 mA cm−2, PRC greatly reduces alkaline HER overpotentials from 540 to 380 mV. And Ru@PRC even exhibits low overpotentials of 28 and 275 mV to reach current densities of 10 and 1000 mA cm−2, respectively. Impressively, the mass activity and price activity of Ru@PRC are 7.83 and 15.7 times higher than that of Pt/C at the overpotential of 50 mV. Our data unveil the positive HER reactivity of pentagonal defects and good application prospects.

AbstractPrecursor solution aging process can cause significant influence on the photovoltaic performance of perovskite solar cells (PVSCs). Notably, we first observe that the aging phenomenon is more severe in the precursor of two‐step sequential method compared to that in one‐step method due to that the protic solvent isopropanol facilitates amine‐cation side reaction and iodide ions oxidation. Herein, we report a novel approach for selectively stabilizing both organic amine salt and lead iodide (PbI2) precursor solutions in two‐step method. The introduction of benzene‐1,3‐dithiol into organic amine salt solution can mitigate amine‐cation side reactions due to the formation of an acidic and reducing environment. Simultaneously, decamethylferrocene (FcMe10/FcMe+10) pair can act as a redox shuttle in PbI2 solution to concurrently oxidize Pb0 and reduce I2 in cyclic manner. Consequently, the PVSCs device fabricated from ameliorative precursor solutions demonstrates superior power conversion efficiency of 25.31 %, retaining 95 % of its efficiency after 21 days of solution aging. Moreover, the unencapsulated devices maintain 85 % of primitive efficiency for 1500 h at maximum power point tracking under continuous illumination. This work establishes a fundamental guidance and scientific direction for the stabilization of two‐step perovskite precursor solutions.

AbstractRationally designing a current collector that can maintain low lithium (Li) porosity and smooth morphology while enduring high‐loading Li deposition is crucial for realizing the high energy density of Li metal batteries, but it is still challengeable. Herein, a Li2ZnCu3 alloy‐modified Cu foil is reported as a stable current collector to fulfill the stable high‐loading Li deposition. Benefiting from the in situ alloying, the generated numerous Li2ZnCu3@Cu heterojunctions induce a homogeneous Li nucleation and dense growth even at an ultrahigh capacity of 12 mAh cm−2. Such a spatial structure endows the overall Li2ZnCu3@Cu electrode with the manipulated steric hindrance and outmost surface electric potential to suppress the side reactions during Li stripping and plating. The resultant Li||Li2ZnCu3@Cu asymmetric cell preserves an ultrahigh average Coulombic efficiency of 99.2 % at 3 mA cm−2/6 mAh cm−2 over 200 cycles. Moreover, the Li‐Li2ZnCu3@Cu||LiFePO4 cell maintains a cycling stability of 87.5 % after 300 cycles. After coupling with the LiCoO2 cathode (4 mAh cm−2), the cell exhibits a high energy density of 407.4 Wh kg−1 with remarkable cycling reversibility at an N/P ratio of 3. All these findings present a doable way to realize the high‐capacity, dendrite‐free, and dense Li deposition for high‐performance Li metal batteries.

AbstractAdditive manufacturing of (quasi−) solid‐state (QSS) electrochemical energy storage devices (EES) highlights the significance of gel polymer electrolytes (GPEs) design. Creating well‐bonded electrode‐GPEs interfaces in the electrode percolative network via printing leads to large‐scale production of customized EES with boosted electrochemical performance but has proven to be quite challenging. Herein, we report on a versatile, universal and scalable approach to engineer a controllable, seamless electrode‐GPEs interface via free radical polymerization (FRP) triggered by MXene at room temperature. Importantly, MXene reduces the dissociation enthalpy of persulfate initiators and significantly shortens the induction period accelerated by SO4−, enabling the completion of FRP within minutes. The as‐formed well‐bonded electrode‐GPEs interface homogenizes the electrical and concentration fields (i.e., Zn2+), therefore suppressing the dendrites formation, which translates to long‐term cycling (50,000 times), high energy density (105.5 Wh kg−1) and power density (9231 W kg−1) coupled with excellent stability upon deformation in the zinc‐ion hybrid capacitors (ZHCs). Moreover, the critical switch of the rheological behaviours of the polymer electrolyte (as aqueous inks in still state and become solids once triggered by MXene) perfectly ensures the direct all‐printing of electrodes and GPEs with well‐bonded interface in between, opening vast possibilities for all‐printed QSS EES beyond ZHCs.

Published: September 2024

AbstractThe prerequisite for electrocatalytic hydrogenation reactions (EHRs) is H2O splitting to form surface hydrogen species (*H), which occupy catalytic sites and lead to mismatched coverage of *H and reactants, resulting in unsatisfactory activity and selectivity. Thus, modulating the splitting pathway of H2O is significant for optimizing the EHR process. Herein, a Cu−Ag alloy with a superlattice structure of staggered‐ordered Cu and Ag is theoretically predicted and experimentally proven to undergo a pathway for H2O splitting called the hydrogen transfer reaction (HTR) in the water layer, which involves the formation of *H, the capture of *H by a water cluster to form H*(H2O)x and subsequent hydrogenation reactions by H*(H2O)x. Taking acetylene hydrogenation as a model case, the as‐proposed HTR pathway could lead to a relaxation hydrogenation process to modulate the matching degree of C2H2 and *H, thus enabling a 91.2 % C2H4 Faradaic efficiency at a partial current density of 0.38 A cm−2, greatly outperforming its counterpart without a superlattice structure.

Published: September 2024

AbstractMetal–Organic Frameworks (MOFs), praised for structural flexibility and tunability, are prominent catalyst prototypes for exploring oxygen evolution reaction (OER). Yet, their intricate transformations under OER, especially in industrial high‐current environments, pose significant challenges in accurately elucidating their structure–activity correlation. Here, we harnessed an electrooxidation process for controllable MOF reconstruction, discovering that Fe doping expedites Ni(Fe) MOF structural evolution, accompanied by the elongation of Ni−O bonds, monitored by in situ Raman and UV/Visible spectroscopy. Theoretical modeling further reveals that Fe doping and defect‐induced tensile strain in the NiO6 octahedra augments the metal ds‐O p hybridization, optimizing their adsorption behavior and augmenting OER activity. The reconstructed Ni(Fe) MOF, serving as the anode in anion exchange membrane water electrolysis, achieves a noteworthy current density of 3300 mA cm−2 at 2.2 V while maintaining equally stable operation 500 mA cm−2 for 300 h and 1000 mA cm−2 for 170 h. This undertaking elevates our comprehension of OER catalyst reconstruction, furnishing promising avenues for designing highly efficacious catalysts across electrochemical platforms.

AbstractDisrupting the conserved multivalent binding of hemagglutinin (HA) on influenza A virus (IAV) to sialic acids (SAs) on the host cell membrane offers a robust strategy to block viral attachment and infection, irrespective of antigenic evolution or drug resistance. In this study, we exploit red blood cell‐derived small extracellular vesicles (RBC sEVs) as nanodecoys by harnessing their high abundance of surface‐displayed SAs to interact with IAV through multivalent HA‐SA interactions. This high‐avidity binding inhibits viral adhesion to the cell surface, effectively preventing both attachment and infection in a dose‐dependent manner. Notably, enzymatic removal of SAs from RBC sEVs significantly diminishes their anti‐IAV efficacy. Our findings indicate that RBC sEVs possess intrinsic anti‐IAV properties due to their native multivalent SAs and hold considerable promise as antiviral therapeutics.

AbstractCollapsing and degradation of active materials caused by the electrode/electrolyte interface instability in aqueous batteries are one of the main obstacles that mitigate the capacity. Herein by reversing the notorious side reactions include the loss and dissolution of electrode materials, as we applied Ostwald ripening (OR) in the electrochemical cycling of a copper hexacyanoferrate electrode in a hydronium‐ion batteries, the dissolved Cu and Fe ions undergo a crystallization process that creates a stable interface layer of cross‐linked cubes on the electrode surface. The layer exposed the low‐index crystal planes (100) and (110) through OR‐induced electrode particle growth, supplemented by vacancy–ordered (100) superlattices that facilitated ion migration. Our design stabilized the electrode–electrolyte interface considerably, achieving a cycle life of one million cycles with capacity retention of 91.6 %, and a capacity retention of 91.7 % after 3000 cycles for a full battery.

AbstractElectrochemical urea oxidation reaction (UOR) offers a promising alternative to the oxygen evolution reaction (OER) in clean energy conversion and storage systems. Nickel‐based catalysts are regarded as highly promising electrocatalysts for the UOR. However, their effectiveness is significantly hindered by the unavoidable self‐oxidation reaction of nickel species during UOR. To address this challenge, we proposed an interface chemistry modulation strategy to boost UOR kinetics by creating a high‐energy interfacial heterostructure. This heterostructure incorporates Ag at the CoOOH@NiOOH heterojunction interface, where strong interactions significantly promote the electron exchanges at the heterojunction interface between ‐OH and ‐O groups. Consequently, the improved electron delocalization leads to the formation of stronger bonds between Co sites and urea CO(NH2)2, promoting a preference for urea to occupy Co active sites over OH*. The resulting catalyst, Ag−CoOOH@NiOOH, demonstrates ultrahigh UOR activity with a low potential of 1.33 V at 100 mA cm−2. The fabricated catalyst exhibits a mass activity over 11.9 times greater than the initial cobalt oxyhydroxide. The rechargeable urea‐assisted zinc‐air batteries (ZABs) achieve a record‐breaking energy efficiency of 74.56 % at 1 mA cm−2, remarkable durability (1000 hours at a current density of 50 mA cm−2), and quick charge performances.

AbstractUnconventional 1T′ phase transition metal dichalcogenides (TMDs) show great potential for hydrogen evolution reaction (HER). However, they are susceptible to transitioning into the stable 2H phase, which reduces their catalytic activity and stability. Herein, we present a scalable approach for designing thermally stable 1T′‐TMDs hollow structures (HSs) by etching Cu1.94S templates from pre‐synthesized Cu1.94S@TMDs heterostructures, including 1T′‐MoS2, MoSe2, WS2, and WSe2 HSs. Furthermore, taking 1T′‐MoS2 HSs as an example, the etched Cu ions can be firmly adsorbed on their surface in the form of single atoms (SAs) through Cu−S bonds, thereby elevating the phase transition temperature from 149 °C to 373 °C. Due to the advantages conferred by the 1T′ phase, hollow structure, and synergistic effect between Cu SAs and 1T′‐MoS2 supports, the fabricated 1T′‐MoS2 HSs demonstrate superior HER performance. Notably, their high‐phase stability enables continuous operation of designed 1T′‐MoS2 HSs for up to 200 hours at an ampere‐level current density without significant activity decay. This work provides a universal method for synthesizing highly stable 1T′‐TMDs electrocatalysts, with a particular focus on the relationship between their phase and catalytic stability.
