AbstractP‐type organic cathode materials typically exhibit high redox potentials and fast redox kinetics, presenting broad application prospects in aqueous zinc batteries (AZBs). However, most of the reported p‐type organic cathode materials exhibit limited capacity (<100 mAh g−1), which is attributable to the low mass content ratio of oxidation‐reduction active functional groups in these materials. Herein, we report a high‐capacity p‐type organic material, 5,12‐dihydro‐5,6,11,12‐tetraazatetracene (DHTAT), for aqueous zinc batteries. Both experiments and calculation indicate the charge storage of DHTAT mainly involves the adsorption/desorption of ClO4− on the −NH− group. Benefitting from the high mass content ratio of the −NH− group in DHATA molecule, the DHATA electrode demonstrates a remarkable capacity of 224 mAh g−1 at a current density of 50 mA g−1 with a stable voltage of 1.12 V. Notably, after 5000 cycles at a high current density of 5 A g−1, DHTAT retains 73 % of its initial capacity, showing a promising cycling stability. In addition, DHTAT also has good low‐temperature performance and can stably cycle at −40 °C for 4000 cycles at 1 A g−1, making it a competitive candidates cathode material for low‐temperature batteries.

Published: September 2024

AbstractThe immunosuppressive tumor microenvironment and limited intratumoral permeation have largely constrained the outcome of tumor therapy. Herein, we report a tailored DNA structure‐based nanoplatform with striking tumor‐penetrating capability for targeted remodeling of the immunosuppressive tumor microenvironment in vivo. In our design, chemo‐immunomodulator (gemcitabine) can be precisely grafted on DNA sequences through a reactive oxygen species (ROS)‐sensitive linker. After self‐assembly, the gemcitabine‐grafted DNA structure can site‐specifically organize legumain‐activatable melittin pro‐peptide (promelittin) on each vertex for intratumoral delivery and further function as the template to load photosensitizers (methylene blue) for ROS production. The tailored DNA nanoplatform can achieve targeted accumulation, highly improved intratumoral permeation, and efficient immunogenic cell death of tumor cells by laser irradiation. Finally, the immunosuppressive tumor microenvironment can be successfully remodeled by reducing multi‐type immunosuppressive cells and enhancing the infiltration of cytotoxic lymphocytes in the tumor. This rationally developed multifunctional DNA nanoplatform provides a new avenue for the development of tumor therapy.

AbstractFabrication of ion‐conducting membranes with continuous sub‐nanometer channels holds fundamental importance for flow batteries in achieving safe integration of renewable energy into grids. Self‐standing covalent organic polymer (COP) membranes provide feasibility due to their rapid and selective ion transport. However, the development of a scale‐up possible, mechanically robust and chemically stable membranes remains a significant challenge. Herein, using irreversible strong secondary amine linkage, we propose a self‐standing COP membrane with sub‐nanometer pores ranging from 4.5 to 6.4 Å, by a simple and efficient in situ polymerization approach. This membrane exhibits enhanced selectivity for proton and vanadium ions, especially excellent electrochemical stability, delivering an energy efficiency of over 80 % at the current density of 200 mA cm−2 over 1000 cycles for an all‐vanadium redox flow battery (VFB). This study provides novel insights for COP‐based ion‐sieving membranes in sustainable energy fields.

AbstractMembrane fission involves a crucial step of lipid remodeling, in which the dynamin collar constricts and severs the tubulated lipid membrane at the neck of budding vesicles. Nevertheless, the difficulty in accurately determining the rotational dynamics of live endocytotic vesicles poses a limit on the elucidation of dynamin‐induced membrane remodeling for endocytotic vesicle scission. Herein, we designed a DNA‐modified gold homodimer (AuHD)‐based anisotropic plasmonic probe with uniform surface chemistry, minimizing orientational fluctuation within vesicle encapsulation. Using AuHDs as cargos to image the dynamics of cargo‐containing vesicles during endocytosis, we showed that, prior to detachment from plasma membrane, the cargo‐containing vesicles underwent multiple intermittent twists of ~4° angular orientation relative to plasma membrane with a ~0.2 s dwell time. These findings suggest that the membrane torques resulting from dynamin actions in vivo constitute the pathway to membrane fission, potentially shedding light on how dynamin‐mediated lipid remodeling orchestrates membrane fission.

AbstractHelical foldamers have attracted much attention over the last decades given their resemblance to certain biomacromolecules and their potential in domains as different as pharmaceutics, catalysis and photonics. Various research groups have successfully controlled the right‐ or left‐ handedness of these oligomers by introducing stereogenic centers through covalent or non‐covalent chemistry. However, developing helical structures whose handedness can be reversibly switched remains a major challenge for chemists. To date, such an achievement has been reported with light‐responsive single‐stranded foldamers only. Herein, we demonstrate that grafting a unidirectional motor onto foldamer strands constitutes a relevant strategy to i) control the single or double helical state of a foldamer, ii) switch on the chiral induction process from the motor to the helical strands and iii) select the handedness of double helical structures through photochemical and thermal stimulations.

Published: September 2024

AbstractIn the polymerization‐induced chiral self‐assembly (PICSA) process, chiral functional monomers undergo spontaneous supramolecular self‐assembly and asymmetric stacking during living polymerization, leading to the in situ generation of chiroptical polymer assemblies characterized by diverse morphologies. The PICSA strategy facilitates precise control and manipulation of both non‐covalent supramolecular helices and covalent macromolecular helices within aggregated cores, thereby driving significant advancements in fields such as chiral recognition materials, asymmetric catalysts, nonlinear optical materials, and ferroelectric liquid crystals (LC). This minireview summarizes recent developments in the in situ chiroptical construction and modulation associated with the PICSA methodology. Furthermore, it seeks to elucidate emerging PICSA systems founded on various living polymerization mechanisms, exploring hierarchical chirality transfer processes and the pathway complexities in both equilibrium and non‐equilibrium conditions. This minireview also presents several illustrative examples that demonstrate the practical applications of chiral polymer materials synthesized through the PICSA approach, thereby illuminating future opportunities in this innovative field.

AbstractMultiple resonance (MR) boron–nitrogen doped polycyclic aromatic hydrocarbons (BN‐PAHs) have shown compelling thermally activated delayed fluorescence (TADF), surpassing those of their hydrocarbon analogues. However, the structural variety of π‐extended BN‐PAHs remains narrow. In this study, we synthesized three double helical BN‐doped nanographenes (BN‐NGs), 2 a–2 c, and three heptagon‐embedded BN‐NGs, 1 a–1 c, by π‐extension of the MR core. During the formation of 2 a, a nanographene with one heptagon (1 a) was obtained, whereas further dehydrocyclization of the [6]helicene units within 2 b and 2 c led to heptagon structures, yielding other two BN‐NGs containing double heptagons (1 b and 1 c). These BN‐NGs (2 a–2 c and 1 a–1 c) showed pronounced redshifts of 100–190 nm compared to the parent MR core, while preserving the TADF characteristics and prolonging the delayed fluorescence lifetime to the millisecond level. Furthermore, the integration of a heptagon ring into 1 a–1 c expanded the conjugation, reduced the oxidation potentials, and yielded a more flexible framework compared to those of 2 a–2 c. The enantiomers of 2 a–2 c, 1 a, and 1 c were resolved and their chiroptical properties were studied. Notably, 1 a and 1 c exhibited increased chiroptical dissymmetry factors.

Published: September 2024

AbstractNa2WO4/SiO2, a material known to catalyze alkane selective oxidation including the oxidative coupling of methane (OCM), is demonstrated to catalyze selective hydrogen combustion (SHC) with >97 % selectivity in mixtures with several hydrocarbons (CH4, C2H6, C2H4, C3H6, C6H6) in the presence of gas‐phase dioxygen at 883–983 K. Hydrogen combustion rates exhibit a near‐first‐order dependence on H2 partial pressure and are zero‐order in H2O and O2 partial pressures. Mechanistic studies at 923 K using isotopically‐labeled reagents demonstrate the kinetic relevance of H−H dissociation and absence of O‐atom recombination. In situ X‐ray diffraction (XRD) and W LIII‐edge X‐ray absorption spectroscopy (XAS) studies demonstrate, respectively, a loss of Na2WO4 crystallinity and lack of second‐shell coordination with respect to W6+ cations below 923 K; benchmark experiments show that alkali cations must be present for the material to be selective for hydrogen combustion, but that materials containing Na alone have much lower combustion rates (per gram Na) than those containing Na and W. These data suggest a synergy between Na and W in a disordered phase at temperatures below the bulk melting point of Na2WO4 (971 K) during SHC catalysis. The Na2WO4/SiO2 SHC catalyst maintains stable combustion rates at temperatures ca. 100 K higher than redox‐active SHC catalysts and could potentially enable enhanced olefin yields in tandem operation of reactors combining alkane dehydrogenation with SHC processes.

AbstractDual‐atom catalysts (DACs) have garnered significant interest due to their remarkable catalytic reactivity. However, achieving atomically precise control in the fabrication of DACs remains a major challenge. Herein, we developed a straightforward and direct sublimation transformation synthesis strategy for dual‐atom Fe catalysts (Fe2/NC) by utilizing in situ generated Fe2Cl6(g) dimers from FeCl3(s). The structure of Fe2/NC was investigated by aberration‐corrected transmission electron microscopy and X‐ray absorption fine structure (XAFS) spectroscopy. As‐obtained Fe2/NC, with a Fe−Fe distance of 0.3 nm inherited from Fe2Cl6, displayed superior oxygen reduction performance with a half‐wave potential of 0.90 V (vs. RHE), surpassing commercial Pt/C catalysts, Fe single‐atom catalyst (Fe1/NC), and its counterpart with a common and shorter Fe−Fe distance of ~0.25 nm (Fe2/NC‐S). Density functional theory (DFT) calculations and microkinetic analysis revealed the extended Fe−Fe distance in Fe2/NC is crucial for the O2 adsorption on catalytic sites and facilitating the subsequent protonation process, thereby boosting catalytic performance. This work not only introduces a new approach for fabricating atomically precise DACs, but also offers a deeper understanding of the intermetallic distance effect on dual‐site catalysis.

Published: September 2024

AbstractSolid‐state potassium metal batteries are promising candidates for grid‐scale energy storage due to their low cost, high energy density and inherent safety. However, solid state K‐ion conductors struggle with poor ionic conductivity due to the large ionic radius of K+‐ions. Herein, we report precise regulation of phase heterogeneity and reciprocity of the P2/P3‐symbiosis K0.62Mg0.54Sb0.46O2 solid electrolyte (SE) for boosting a high ionic conductivity of 1.6×10−4 S cm−1 at 25 °C. The bulk ionic conducting mechanism is explored by elucidating the effect of atomic stacking mode within the layered framework on K+‐ion migration barriers. For ion diffusion at grain boundaries, the P2/P3 biphasic symbiosis property assists in tunning the SE microstructure, which crystallizes in rod‐like particles with lengths of tens of micrometers facilitating long‐distance ion transport and significantly decreasing grain boundary resistance. Potassium metal symmetric cells using the modified SE deliver excellent cycling life over 300 h at 0.1 mA cm−2 and a high critical current density of 0.68 mA cm−2. The quasi‐solid‐state potassium metal batteries (QSSKBs) coupled with two kinds of layered oxide cathodes demonstrate remarkable stability over 300 cycles, outperforming the liquid electrolyte counterparts. The QSSKB system provides a promising strategy for high‐efficiency, safe, and durable large‐scale energy storage.

AbstractManipulating the atomic structure of the catalyst and tailoring the dissociative water‐hydrogen bonding network at the catalyst‐electrolyte interface is essential for propelling alkaline hydrogen evolution reaction (HER) and hydrazine oxidation reaction (HzOR), but remains a great challenge. Herein, we constructed an advanced a‐RuMo/NiMoO4/NF heterogeneous electrocatalyst with amorphous RuMo alloy nanoclusters anchored to amorphous NiMoO4 skeletons on Ni foam by a heteroatom implantation strategy. Theoretical calculations and in situ Raman tests show that the amorphous and alloying structure of a‐RuMo/NiMoO4/NF not only induces the directional evolution of interfacial H2O, but also lowers the d‐band center (from −0.43 to −2.22 eV) of a‐RuMo/NiMoO4/NF, the Gibbs free energy of hydrogen adsorption (ΔGH*, from −1.29 to −0.06 eV), and the energy barrier of HzOR (ΔGN2(g)=1.50 eV to ΔGN2*=0.47 eV). Profiting from these favorable factors, the a‐RuMo/NiMoO4/NF exhibits excellent electrocatalytic performances, especially at large current densities, with an overpotential of 13 and 129 mV to reach 10 and 1000 mA cm−2 for HER. While for HzOR, it needs only −91 and 276 mV to deliver 10 and 500 mA cm−2, respectively. Further, the constructed a‐RuMo/NiMoO4/NF||a‐RuMo/NiMoO4/NF electrolyzer demands only 7 and 420 mV to afford 10 and 500 mA cm−2.

AbstractEnrichment of photosensitizers (PSs) on cancer cell membranes via bioorthogonal reactions is considered to be a very promising therapeutic modality. However, azide‐modified sugars‐based metabolic labeling processes usually lack targeting and the labeling speed is relatively slow. Moreover, it has been rarely reported that membrane‐anchoring pure type‐I PSs can induce cancer cell pyroptosis. Here, we report an alkaline phosphatase (ALP) and cholecystokinin‐2 receptor (CCK2R) dual‐targeting peptide named DBCO‐pYCCK6, which can selectively and rapidly self‐assemble on cancer cell membrane, and then bioorthogonal enrich type‐I aggregation‐induced emission luminogens (AIEgen) PSs (SAIE‐N3) on the cell membrane. Upon light irradiation, the membrane‐anchoring SAIE‐N3 could effectively generate type‐I reactive oxygen species (ROS) to induce gasdermin E (GSDME)‐mediated pyroptosis. In vivo experiments demonstrated that the bioorthogonal combination strategy of peptide and AIEgen PSs could significantly inhibit tumor growth, which is accompanied by CD8+ cytotoxic T cell infiltration. This work provides a novel self‐assembly peptide‐mediated bioorthogonal reaction strategy to bridge the supramolecular self‐assembly and AIE field through strain‐promoted azide‐alkyne cycloaddition (SPAAC) and elucidates that pure type‐I membrane‐anchoring PSs can be used for cancer therapy via GSDME‐mediated pyroptosis.

AbstractNeuromorphic computing, marked by its parallel computational abilities and low power usage, has become pivotal in advancing artificial intelligence. However, the advancement of neuromorphic computing has faced significant obstacles due to the performance limitations of traditional memory devices struggling with high power consumption and limited reliability. Two‐dimensional (2D) materials have been extensively investigated as high‐performance memristive materials, but they are often restricted by fixed memristive properties, which complicate circuit design and limit flexibility. Here, we report that multilayer borophene nanosheets represent a breakthrough material, displaying anisotropic variable memristive properties. The nanosheets, comprising semiconductor α’‐4H‐borophene sheets and metal β12‐borophene sheets, have been synthesized on aluminum foil surface through chemical vapor deposition method. The multilayer borophene nanosheets exhibit volatile memory behavior in the vertical direction and non‐volatile memory behavior in the planar direction. This innovative class of 2D nanosheets not only overcomes the limitations of conventional memory devices but also expands the potential applications of borophene‐based memories in information storage and in‐memory computing.

Published: September 2024

AbstractFor rechargeable magnesium batteries, chlorine‐containing electrolytes are used because chlorine species reduce the energy barrier for the intercalation process at the cathode. However, these species can cause corrosion of the cathode‐side current collectors during polarization. In this study, carbon‐coated aluminum and Nickel metal substrates, as well as a graphite foil, were investigated using Linear Sweep Voltammetry, Chronoamperometry, and Electrochemical Impedance Spectroscopy to evaluate their potential as current collectors in APC electrolyte. The graphite‐based current collector withstood corrosive environments at polarization potentials up to 2 V, displaying passivating behavior comparable to platinum in Chronoamperometry measurements. During Electrochemical Impedance Spectroscopy measurements, the graphite foil exhibited exceptionally high polarization resistance of at least 4.5 MΩ cm2. Combined with its low areal density of 5 mg/cm−2, this makes it an excellent current collector material for rechargeable magnesium batteries with chlorine‐containing electrolytes. In contrast, Al foil are instable towards corrosion – despite protective coatings.

AbstractBackgroundColorectal cancer (CRC) is a prevalent and lethal tumor, with metastasis being the leading cause of mortality. Previous research has indicated that the long non‐coding RNA (lncRNA) CCAT2 is involved in the regulation of various tumor progression mechanisms. However, the precise role of CCAT2 in CRC proliferation and metastasis remains ambiguous. This study seeks to elucidate the mechanisms through which CCAT2 influences CRC.MethodsHigh‐throughput sequencing and RT‐qPCR were used to detect CCAT2 expression in CRC. Functional analyses including CCK8, colony formation, wound healing migration, transwell chamber, and Muse® Cell Analyzer assays were performed to study the effects of CCAT2 gene deletion on CRC cells. RNA‐pulldown and protein mass spectrometry were employed to identify the interaction between CCAT2 and GNB2 protein.ResultsIncreased CCAT2 expression was found in CRC, especially in metastatic CRC. Deletion of CCAT2 gene inhibited CRC cell proliferation, migration, and invasion while promoting apoptosis. The interaction between CCAT2 and GNB2 protein was shown to modulate GNB2 protein alterations and affect the ERK and Wnt signaling pathways, thereby promoting CRC proliferation and metastasis.ConclusionCCAT2 plays a crucial role in CRC progression by modulating the ERK and Wnt signaling pathways through its interaction with GNB2. These findings highlight the importance of CCAT2 as a key regulatory element in the mechanisms underlying CRC proliferation and metastasis.
