AbstractPractical implementations of solid polymer electrolytes (SPEs) in solid‐state lithium‐metal batteries (SSLMBs) are inhibited by the limited lithium‐ion (Li+) transport and poor‐quality interface between SPEs and both electrodes. SPEs exhibit lower ionic conductivity than other electrolytes and are oxidized and decomposed by oxide‐based cathode materials in high‐voltage windows. SSLMBs are also long‐term destabilized by parasitic side reactions at the electrode–electrolyte interfaces and Li dendrite formations. This study proposes a selectively designed Janus‐structured polymer electrolyte (JPE), which is more physically and chemically compatible with the electrodes than other SPEs. The proposed JPE includes a cathode‐facing composite polymer electrolyte (C‐CPE) containing succinonitrile and Li7La3Zr2O12, and an anode‐facing composite polymer electrolyte (A‐CPE) incorporating fluoroethylene carbonate (FEC). The C‐CPE layer provides additional Li+ paths and increases the antioxidant properties, improving the high‐voltage tolerance of the SSLMB, while the A‐CPE layer alleviates side reactions with the Li metal anode and improves the stability against protruding dendrites. Full cells of Li|JPE|Ni0.8Co0.15Al0.05O2 and Li|JPE|LiCoO2 remain stable over 1600 cycles at 1 C, demonstrating the potential of the JPE structures for SSLMBs. Moreover, symmetric Li||Li cells assembled with the JPE cycle over 2500 h at 0.1 mA cm−2 and 1000 h at 0.5 mA cm−2.

AbstractPyrophosphate Na3.12Fe2.44(P2O7)2 (NFPO) has triggered widespread attention due to its high safety and robust framework. However, it suffers from low energy density due to the limited specific capacity and partial low voltage plateau (≈2.5 V vs Na+/Na). Regulating such low voltage plateau can be a promising way to increase the energy density of NFPO. As revealed by the systematic characterizations and theoretical calculations, the low‐voltage plateau results from the Fe1 site (corner‐sharing mode) redox reaction accompanied by Na4 insertion/extraction process. Accordingly, in this work, a precise Ti3+ doping strategy is proposed to selectively occupy the Fe1 site based on the energy effect, thus boosting the energy density from 277.5 to 307.7 Wh kg−1 due to the improved reversible capacity (109.8 mAh g−1) and regulated voltage plateau. Reversible structural evolution with very tiny volume variation (3%) due to the strengthened local environment (Ti─O bonds) promises outstanding cycling durability (90.3% capacity retention over 4000 cycles). Moreover, fast reaction kinetics and low diffusion energy barriers achieved by introducing Ti3+ contribute to the excellent rate capability. This lattice regulation strategy enables NFPO cathode with superior performance and can provide deep guidelines for designing advanced polyanion cathodes.

AbstractThermal energy regulation is a significant challenge, contributing to over 30% of annual greenhouse gas emission (GHG) emissions. Phase change materials (PCMs) offer a promising solution by storing thermal energy, which can enable the reuse of waste heat for heating and cooling; however, developing materials for shape‐stabilized PCMs remains crucial. This work investigates a self‐foaming poly(hydroxy)urethane (PHU), derived from a non‐isocyanate polyurethane (NIPU), as a porous support for shape‐stabilizing paraffinic and salt hydrate PCMs. PHU‐encapsulated paraffinic PCMs exhibited excellent thermal stability over repeated cycles. Thermal stability with salt hydrate PCMs, specifically calcium chloride hexahydrate (CaCl2•6H2O), is achieved by the incorporation of 5 wt.% barium carbonate (BaCO3) into the PHU foam. This enabled stable cycling for over 48 cycles with desirable thermal properties, i.e., a melting point ≈30 °C, high enthalpy (ca. 138 J g−1 per cycle), and a consistent freezing point ≈20 °C, making it suitable for applications in buildings and electric vehicle battery insulation. Also, incorporating graphite (1.5–10 wt.%) into the foam enhanced the thermal conductivity of shape‐stabilized CaCl2•6H2O during heating and cooling cycles. Overall, the approach detailed here offers a carbon‐conscious and chemically tunable material for thermal energy storage.

AbstractFlexible self‐powered sensors with the significant ability to the information perception, decoding, and conveying processes have attracted tremendous attention in healthcare monitoring, motion detection, and intelligent interaction. Also, the solar thermoelectric technology holding the effective solar energy/heat harvesting capacity for sustainable electricity generation shows attractive prospects in self‐powered wearable sensing but is terribly limited by its poor flexibility and complex construction. Herein, a solar thermoelectric system, prepared via facilely sandwiching the self‐assemble MoS2/Carbon hollow nanoflower‐based fabrics with [Fe(CN)6]3‐/4− thermoelectric gels, is successfully applied for the self‐powered wearable sensing. Owing to the hollow‐heterostructure for the strong light absorption, MoS2/Carbon hollow nanoflower‐based fabrics demonstrated a photothermal conversion efficiency of 39.6%. The strong heat concentration can supply a considered temperature gradient of 42.7 K for thermoelectric gels with a Seebeck coefficient of 1.08 mV K−1 under a solar intensity of 1 sun, outputting a voltage density of 101.2 V m−2 with a response of 431 ms. Their promising application in self‐powered wearable fields, such as noncontact motion monitoring and language interaction is foreseen.

AbstractPerovskite light‐emitting diodes (PeLEDs) have recently attracted great interest for their superior electroluminescent properties. However, the development of pure red (620–660 nm) PeLEDs as an essential component for display applications continues to be hampered by severe nonradiative recombination. Particularly, the solution fabrication process of perovskites poses a challenge in the fabrication of white PeLEDs, which further hinders their commercialization. Herein, a novel design is reported of high‐efficiency hybrid perovskite/organic tandem white light‐emitting diodes (POTWLEDs) by integrating bottom pure red (640 nm) PeLED units with top blue OLED units. To optimize device performance, 5‐Bromo‐2‐fluoropyridine (PD) is introduced, featuring strong electronegative groups of C─N and C─F, as a pyridine passivator into pure red PeLEDs to inhibit nonradiative recombination in the perovskites by passivating defects and improving phase purity of perovskite films, which promotes a maximum external quantum efficiency (EQE) of 20.4%. By integrating the optimized red PeLED units with blue OLED units, efficient POTWLEDs are obtained with high EQE values of 25.9 and 23.7% with CIE coordinates of (0.279 and 0.339) and (0.310 and 0.330), respectively. These values represent the highest efficiencies reported for perovskite‐based white light‐emitting diodes (WLEDs), illustrating the great potential for solid‐state lighting and display applications.

AbstractRecombination is one of the main factors that cause the large open‐circuit voltage deficit (Voc, def) in Cu2ZnSn(S,Se)4 (CZTSSe) solar cells. To mitigate this issue, an effective strategy is developed to suppress the recombinations in CZTSe devices by doping Ge in the absorber. A certified efficiency of 14.67%(total area: 0.3143 cm2, without an anti‐reflective layer) was achieved in optimally Ge‐doped CZTSe solar cells. In addition to promoting the grain growth, Ge doping induces more pronounced downward band‐bending, effectively passivating GBs and suppressing recombination in the quasi neutral region (QNR). While optimal Ge doping reduces the number of CuZn defects, excessive Ge doping leads to additional Sn loss, resulting in the formation of deep‐level defects such as VSn. Furthermore, the incorporation of Ge resulted in the formation of residual SnSex secondary phases near the rear interface, highlighting the need for precise cation ratio adjustments in the precursor films. This work reveals the mechanism underlying Ge doping, demonstrating it potential to mitigate the high recombination velocity at GBs, providing a pathway for achieving high‐efficiency CZTSe solar cells.

AbstractNonaromatic amino acids with intrinsic photoluminescence (PL) have drawn growing attention due to their crucial role in the luminescence of natural proteins. However, the weak luminescence significantly constrains the study of specific photophysical processes, emission mechanism of biomolecules, and their applications. Here, a serendipitous finding of synergistic PL enhancement by coupling nonaromatic amino acids and sugars via glycosidic bonds is reported. For example, the crystals of glucose, L‐serine, alongside their corresponding disaccharide and dipeptide are weakly emissive, while glycosylation drastically boosts the quantum yields of L‐serine crystals from 0.3% to as high as 9.2%, accompanied by the emergence of pronounced persistent room temperature phosphorescence (p‐RTP). This synergistic PL enhancement arises from the ingenious integration of the electron‐rich oxygen clusters present in sugar with the charge separation characteristics of amino acids. Furthermore, the ultrafast femtosecond to nanosecond transient absorption spectroscopy and theoretical calculations further reveal the importance of hybridization of locally excited and charge transfer states for PL enhancement and p‐RTP features. These results not only provide a universal strategy for constructing efficient nonconventional luminophores but also shed new light on the underlying mechanism of biological autofluorescence.

AbstractCircularly polarized luminescence (CPL) holds great potential for next‐generation display techniques. However, dynamic, multicolor CPL with high luminescent quantum yield (PLQY) and tunable dissymmetry factor (glum) based on cost‐effective, sustainable materials is scarcely attainable. Herein, a straightforward approach is proposed for engineering cellulose nanocrystal (CNC) chiral superstructures loaded with aggregation‐induced emission luminogens (AIEgens) through the evaporation‐induced self‐assembly of renewable CNCs and tetra‐(4‐pyridylphenyl)ethylene molecules. The judicious design of two building blocks as chiral donor–acceptor pairs not only respectively achieves an 86‐fold and 2.1‐fold improvement in the PLQY of resulting systems in the suspension and aggregate states in comparison with bare AIEgens, but also endows AIEgen‐loaded CNC chiral superstructures with pH‐tunable, humidity‐responsive, multicolor CPL with a maximal |glum| of 0.89. It is revealed that chiral induction and photonic bandgap effects—which are dominated by chiral donor–acceptor interactions and homogeneous or heterogeneous self‐assembly processes—are involved in CPL mechanisms. Finally, humidity‐responsive multiple changes (structural color, fluorescent color, CPL) are realized in both biobased inks and films, which is of paramount importance for potential applications in multicolor dynamic display and information encryption. This work offers the underlying insights for the construction of cost‐effective, renewable superstructures with dynamically tunable CPL.

AbstractPerovskite light‐emitting diodes (PeLEDs) has emerged as one of the most promising technologies for the next generation of lighting and high‐definition display applications due to their exceptional color purity, tunable color emission, and low material costs. In the past eleven years, PeLEDs have made remarkable progress as researchers have come up with many innovative approaches. Among them, additive engineering based on small organic molecules (SOMs) has been demonstrated as one of the most effective strategies to enhance the external quantum efficiency (EQE) and stability of PeLEDs. Notably, the champion EQEs for red, green, and blue devices cannot be realized without the participation of SOMs. Here, this paper first reviews the development of PeLEDs, followed by a focused discussion on the specific application and mechanism of SOMs in PeLEDs. Lastly, it analyzes the challenges and provides an outlook on their future development.

AbstractMemristors based on perovskite materials demonstrate significant potential for applications in information encryption and storage. However, the stability and durability of their device structures remain major challenges for commercial deployment. In this study, Mn:CsPbCl3 perovskite nanocrystals capped with short‐chain ligands are synthesized at a controlled ratio using an in situ ligand passivation strategy. Compared with long‐chain ligands, short‐chain ligands possess higher surface adsorption energy, which enhances nanocrystal size uniformity and enables more effective attachment to the perovskite surface at adsorption sites. This process mitigates surface defects in the nanocrystals, thereby decreasing the randomness in conductive filaments formation and enhancing device stability. Furthermore, short‐chain ligand capping improves the contact at the material‐electrode interface correspondingly reducing leakage current. The fabricated short‐chain Al/Mn:CsPbCl3/FTO memristor exhibits good reconfigurable storage behavior. By adjusting the compliance current, a transition from non‐volatile to volatile storage modes is successfully achieved. Leveraging the device's electrical characteristics, binary image encryption, and storage functions are realized. Overall, this work demonstrates the importance of surface defects on the operational stability of nanocrystal memristors and provides a foundation for the application of perovskite memristors in information encryption and secure transmission.

AbstractMost seasonal and pandemic influenza vaccines are derived from inactivated or attenuated virus propagated in chicken eggs, while more advanced delivery technologies, such as the use of recombinant proteins and adjuvants, are under‐utilized. In this study, the E2 protein nanoparticle (NP) platform is engineered to synthesize vaccines that simultaneously co‐deliver influenza hemagglutinin (H5) antigen, TLR5 agonist flagellin (FliCc), and TLR9 agonist CpG 1826 (CpG) all on one particle (termed H5‐FliCc‐CpG‐E2), with uniform molecular orientation significant for immunomodulation. Antigen‐bound NP formulations elicit higher IgG antibody responses and broader homosubtypic cross‐reactivity against different H5 variants than unconjugated antigen alone. IgG1/IgG2c skewing is modulated by adjuvant type and NP attachment. Conjugation of flagellin to the NP causes significant IgG1 (Th2) skewing while attachment of CpG yields significant IgG2c (Th1) skewing, and simultaneous conjugation of both flagellin and CpG results in a balanced IgG1/IgG2c (Th2/Th1) response. Animals immunized with E2‐based NP vaccines and subsequently challenged with H5N1 influenza show 100% survival, and only animals that receive adjuvanted NP formulations are also protected against morbidity. This investigation highlights that NP‐based delivery of antigen and multiple adjuvants can be designed to effectively modulate the strength, breadth toward variants, and bias of an immune response against influenza viruses.

AbstractThe accurate diagnosis of pancreatic ductal adenocarcinoma (PDAC) suffers low specify, and low sensitivity of biomarker detection. In complex biological fluid environments, nonspecific adsorption is prevalent, posing challenges to the accurate detection of biomarkers at low concentrations. Herein, a highly sensitive and selective solution‐gated graphene transistor (SGGT) is fabricated for the detection of miRNA‐196a in exosomes to diagnose PDAC. The antifouling modification on the surface of the gate electrode is employed through using bovine serum albumin as a common sealing agent and poly adenine (polyA8) to enhance surface hydrophilicity. The effect of background noise on the detection is effectively reduced. The limit of detection reached 1.82 × 10−19 m without the need for labeling or amplification, and the detection time is within 25 min. The clinical experiments verify that receiver operating characteristic curve values of miRNA‐196a detection in clinical diagnosis are higher than that of carbohydrate antigen 19‐9 biomarker, and are as high as 0.98. The miRNA‐196a detection can well distinguish PDAC from non‐PDAC subjects. The SGGT sensor platform demonstrates significant potential for the accurate detection and diagnosis of PDAC within the milieu of complex biological samples.

Published: February 2025

AbstractAntibiofilm treatment, particularly drug‐containing wound healing dressings, does not typically penetrate the robust protective extracellular polymeric substance of biofilm and eradicate the bacteria. Here, a rational design of nitric oxide (NO) donor N,N'‐di‐sec‐butyl‐N,N'‐dinitroso‐1,4‐phenylenediamine (BNN6)‐based injectable hydrogel, is reported in which the NO release can be triggered by a photothermal effect owing to semiconducting perylene diimide (PDI) J‐aggregation fibers. The synthetic PDI derivatives self‐assembling into 0D nanoparticles and then aggregating to 1D J fiber is accompanied by absorbance red‐shifting from 700 to 790 nm and then to 852 nm. After encapsulating BNN6, a “sandwich roll” (SR) like structure is evenly crosslinked into an injectable hydrogel (SRH) exhibiting a high photothermal convenience efficiency of 72%, which enables the SRH to achieve highly efficient photocontrol NO release. The SRH shows excellent injectability, shape adaptability, and effective antibacterial efficacy over 99% to the E.coli and S. aureus. and remarkable in vivo antibiofilm efficiency of 99.58% by laser irradiation. Furthermore, the synergistic treatment displays the ability to eliminate inflammation, facilitate angiogenesis, and promote collagen deposition, thereby significantly stimulating the healing process of wounds. The semiconducting J‐aggregation injectable hydrogel can be a versatile strategy for the treatment of biofilm.
