Anti-glioma immunotherapy is highly challenging, largely due to poor immune infiltration and restricted immune delivery, resulting in poor patient prognosis. Recent studies suggest that mature tertiary lymphoid structures (mTLSs) promote immune cell infiltration into solid tumors, associated with enhanced immune response and better prognosis. However, the formation and visualization of mTLSs becomes extremely difficult resulting from lack of lymphoid tissue formation microenvironment in the brain parenchyma. Herein, theranostic nanoprobes consisting of FITC-HFe₃O₄@Gd (MRI/FI tracer) and internally loaded chemokines CXCL13 and CCL12 are specifically designed to be internalized by dendritic cells (DCs) into biomimetic nanosystem. Subsequently, labeled DCs are integrated into the mTLSs follicular dendritic cell (fDC) network by crossing the high endothelial venules (HEVs), enabling noninvasive visualization of the mTLSs (e.g., maturation, location, and density) by DC tracer technology. Interestingly, CXCL13 and CCL12 released by labeled DCs stimulate the generation of “immune trafficking bridge” that promote the centripetal redistribution of effector lymphocytes (B220⁺ B and CD8⁺ T cells) within the glioma, thereby further enhancing adaptive immune responses and effectively inhibiting glioma progression in vivo. Consequently, this innovative nanostrategy of biomimetic DCs combining mTLSs formation with MRI/FI tracing enables noninvasive assessment and prediction of beneficial immune responses for clinical translation.

The electrochemical performance of Si anodes for lithium-ion batteries (LIBs) is primarily influenced by the stress–strain and transport dynamics. However, traditional Si/carbon composites often fail to well balance these two factors. Herein, a hierarchically porous silicon/carbon composite (denoted as pSi@void@NMC) with high lithium storage capacity is developed under the guidance of finite element analysis, where porous Si (pSi) and nitrogen-doped mesoporous carbon (NMC) is used as the yolk and shell, respectively. The internal and external cultivation design endows the pSi@void@NMC composite with fast transfer kinetics, effective stress-buffering, low volume expansion, and superior mechanical stability. Compared with core–shell pSi@NMC and bare pSi electrodes, the resulting pSi@void@NMC anode demonstrates a high reversible capacity of 1769.8 mAh g⁻¹ after 300 cycles at 0.2 A g⁻¹ and exceptional cycling stability only with 0.016% capacity decay rate per cycle. In situ and ex situ characterization results further confirm its high reversibility of Li⁺ insertion/extraction during electrochemical reactions benefiting from the formation of inorganic LiF-rich SEI film. Moreover, the developed pSi@void@NMC composite also shows a good potential for full-cell applications. These findings provide a facile design concept and research strategy for addressing stress fractures and inadequate transport kinetics of Si-based anode materials for high-performance LIBs.

The development of aqueous Zn/LiCoO₂ hybrid batteries faces challenges such as poor reversibility, rapid capacity degradation, and severe side reactions in base electrolytes. Herein, this study proposes Al₂O₃ nanoparticles as a bifunctional additive in the base electrolyte, leading to a novel electrolyte that enhances the interfacial stability between electrolyte and electrode and improves the electrochemical performance. Al₂O₃ reduces water molecules activity, inhibits the interfacial side reactions, and enhances the reversibility and stability of redox reactions. Molecular dynamics (MD) simulations reveal that Al₂O₃ modifies the solvation structures of both Li⁺ and Zn²⁺, lowers their de-solvation energies, thereby improving ionic diffusion coefficients and reaction kinetics. Consequently, symmetric cells achieve a prolonged cycle life with uniform zinc deposition. Zn/LiCoO₂ hybrid cells exhibit excellent rate performance, maintaining 81 mAh g⁻¹ at 0.8 A g⁻¹ and stable cycling over 300 cycles at 0.4 A g⁻¹ within a broadened voltage range of 1.5–2.15 V versus Zn/Zn²⁺. Additionally, these cells demonstrate ultrahigh capacity retention of 98.2% at 0 °C and 87% at a high mass loading of 5 mg cm⁻² at 0.4 A g⁻¹. This study presents a promising additive strategy for enhancing the stability and performance of high-voltage aqueous hybrid batteries, paving the way for their practical application.

Membrane covering stents are gaining significant importance in the management of intracavitary diseases, particularly in cases where bare metal stents are inappropriate, such as those involving intracavitary tumors and leaks. It is becoming increasingly important to build an integrated membrane-covered stent. In this study, a metallic stent coated with CaO₂ nanoparticles is fixed in a customized bioreactor. The aggregation of Komagataeibacter xylinus on the stent surface are driven by oxygen release from CaO₂ hydrolysis. Bacterial nanocellulose (BNC) is gradually synthesized in situ, ultimately achieving a BNC membrane covered around the stent's grid and forming an integrated BNC-covered stent. The colonization of bacteria around the stent is confirmed using live/dead bacterial staining kits. This BNC-covered stent maintains the bonding stability between membrane and stent after 10 000 compression cycles, demonstrating 3.5 N stress at 90% compression. After 2 weeks of implantation into the rabbit's trachea, airway patency and epithelial cell survival are 100%, with no inflammation or goblet cell metaplasia. The 3D printing modeling from clinical data shows that the BNC-covered stent loaded with fluorescein isothiocyanate labeled paclitaxel (FITC-PTX) can achieve precise drug delivery in the porcine trachea. The integrated BNC-covered stent provides a promising platform for various intracavitary intervention.

Reservoir computing, distinguished by its reduced training overhead compared to traditional recurrent neural networks, emerges as a proficient architecture for neural networks. Here, an innovative reservoir computing (RC) paradigm based on cavity magnonics for a speech recognition task is demonstrated, which leverages the high tunability, low energy consumption, and fast response of cavity magnon polaritons (CMPs). The audio signal is filtered into a pulse train and then input into the CMP device to rapidly alter the nonlinear dynamics of the CMPs. Due to the short-term memory effect and nonlinear response of the CMP device, virtual nodes are generated in the time domain, forming a recurrent neural network. By maximizing the nonlinear coefficient of the CMP device, exceptional speech recognition accuracy is achieved, with an error rate of less than 0.8%. This work heralds a new era for magnon-based reservoir computing, promising enhanced capabilities for addressing complex temporal tasks in the future.

Solid-state quantum emitters, molecular-sized complexes releasing a single photon at a time, have garnered much attention owing to their use as a key building block in various quantum technologies. Among these, quantum emitters in hexagonal boron nitride (hBN) have emerged as front runners with superior attributes compared to other competing platforms. These attributes are attainable thanks to the robust, two-dimensional (2D) lattice of the material formed by the extremely strong B─N bonds. This review discusses the fundamental properties of quantum emitters in hBN and highlights recent progress in the field. The focus is on the fabrication and engineering of these quantum emitters facilitated by state-of-the-art equipment. Strategies to integrate the quantum emitters with dielectric and plasmonic cavities to enhance their optical properties are summarized. The latest developments in new classes of spin-active defects, their predicted structural configurations, and the proposed suitable quantum applications are examined. Despite the current challenges, quantum emitters in hBN have steadily become a promising platform for applications in quantum information science.

2) In Figure 6D, the tumor tissue images stained with DAPI (blue) and TUNEL (green) in the CaO₂+DOX group show partially overlapping areas when compared to the images of the MDP@Bif group. This error may be attributed to the image of the MDP@Bif group being inadvertently moved to the CaO₂+DOX group during the use of the puzzle software to create the images.

Constructing High-Selective Cation Exchange Membrane via Embedding Sulfonated Lithium-Ion Sieve for Enhanced Lithium Recycling from Spent Batteries Effluents

Recycling of lithium resources from spent battery effluents is critical for their valorization and the amelioration of their adverse environmental effects. Selectrodialysis (SED) based on monovalent-selective electrotransport offers a promising approach for lithium recovery from these streams. However, the separation efficiency is limited by the weak selectivity and stability of monovalent selective cation exchange membranes (MSCEMs) in acidic media. In this study, a highly selective MSCEM is developed by embedding sulfonated hydrogen manganese oxide (HMO) into polyvinylidene fluoride (PVDF) to construct inner Li-ion transport channels. Meanwhile, adjacent oxide groups on the sulfonated HMO surface serve as hopping-sites for fast lithium-ion transport during SED, contributing to a lithium-ion flux of 1.10–2.61 mol m⁻² h⁻¹. Compared with commercial MSCEMs, the membrane developed in this work exhibits a 36-fold increase in the selectivity for lithium separation from co-existing cations (e.g., Co²⁺ and Ni²⁺) and exhibited good stability over 130 h of operation in acidic mixtures. Overall, this study provides a new avenue for the development of Li-selective MSCEM with acid resistance, thereby enhancing the SED-based membrane process for the reclamation of Li resources from spent battery effluents.

High-entropy oxides, with their diverse compositions and entropy-stabilized structures, have emerged as promising candidates for sodium-ion battery cathodes. However, phase transitions in these materials are highly sensitive to the specific transition metal composition, and effective design strategies remain underdeveloped. Herein, a six-element high-entropy layered oxide cathode, O3-Na_0.9Ni_0.3Fe_0.1Zn_0.1Cu_0.05Mn_0.3Ti_0.15O₂, is reported in which the incorporation of Zn and Cu not only alters the electronic structure but also affects the formation angle of desired OP2 phase. By fine-tuning Zn/Cu ratio, we optimize the phase transition behavior of high-entropy layered oxides, significantly enhancing structural stability and electrochemical performance. This material delivers a high specific capacity of 146.9 mAh g⁻¹ with superior cycling performance (80.4% capacity retention after 500 cycles). Furthermore, utilizing the as-prepared cathode and commercial hard carbon anode, 1.1 Ah cylindrical cells successfully demonstrated high initial Coulombic efficiency of 92% and rapid charge and discharge rates up to 5C, retaining 93.6% of the capacity. Notably, these cylindrical cells exhibit excellent cycling stability with capacity retention of 86% after 300 cycles.

Herein, MIL-88b-NH₂ nanocage is designed with adenine inside the cage and tannins as gating outside the cage. Based on this core-shell structure, polyvinyl alcohol/carboxymethyl chitosan/MIL/adenine/tannic acid (PCMAT) hydrogels are able to respond endogenously and exogenously at different stages of wound healing. The engineered hydrogel is designed to have tunable adhesion and intelligence. The optimal PCMAT-0.3 hydrogel reduced the pore size to ≈13.5 µm under endogenous response conditions, and the antimicrobial performance reached more than 80% within 6 h. Tensile strength and strain at break are reduced by 8.47% and 60.52% respectively under exogenous response conditions. Evaluation of the healing effect on mouse back wound tissue shows that the wound healing rate is significantly better than the control group without nanocage incorporation on day 14. It provides an idea for the development of smart response hydrogel wound dressing that integrates multifunctionality.
