The potential use of n-type small organic molecules in electrodes has attracted significant attention in organic electronics owing to the easy, high-yield purification processes of organic compounds. However, only few studies have reported high-efficiency supercapacitors based on n-type organic materials. Nevertheless, most n-type organic compounds possess low capacitance and poor cycling efficiency. Therefore, it is crucial to develop n-type organic compounds that demonstrate good electrochemical properties for use in electrodes. Herein, both the (E)-N-(4-(diphenylamino)benzylidene)-6,6,10,10-tetramethyl-4-phenyl-6,7,8,9,10,10a-hexahydro-5H-6a,9-methanobenzo[H]quinazolin-2-amine (TPAB) and (E)-N-(4-(diphenylamino)benzylidene)-4-(4-(diphenylamino)phenyl)-6,6,10,10-tetramethyl-6,7,8,9,10,10a-hexahydro-5H-6a,9-methanobenzo [h]quinazolin-2-amine (TPANB) compounds containing electrochromic (EC) and aggregation-induced emission (AIE) groups were synthesized from triphenylamine (TPA) and quinazoline derivatives, and their structure and properties were investigated. These novel electrode materials demonstrate high EC and fluorescence performance just as a typical n-type semiconductor. The coloring time of a TPANB film is 4.00 s, whereas the bleaching time is 3.00 s. Compared with TPANB, TPAB electrode material demonstrate a high area-specific capacitance (2.38 mF cm −2 at 0.05 mA cm −2 ), outstanding the charge and discharge rate performance (93% with the current density of 0.05–0.25 mA cm −2 ), and excellent cycling performance (78.51%) after 300 cycles. Above all, the multifunctional materials hold good potential for intelligent display energy storage. Graphical Abstract

A critical challenge in the commercialization of perovskite solar cells (PSCs) is the simultaneous attainment of high power conversion efficiency (PCE) and high stability. Employing polymers interfaces in PSCs can enhance durability by blocking water and oxygen, and by suppressing ions interdiffusion, but their electronic shielding poses a challenge for efficient and stable PSCs 1–3 . In this study, we report a magnetic endohedral metallofullerene Nd@C 82 -polymer coupling layer, which features ultra-fast electron extraction and in-situ encapsulation, thereby promoting homogeneous electron extraction and suppressing ions interdiffusion. The Nd@C 82 -polymer coupling layer in PSCs exhibited PCE of 26.78% (certified 26.29%) and 23.08% with an aperture area of 0.08 square centimetres and 16 square centimetres (modules), respectively. The unencapsulated devices retained ~82% of the initial PCE after 2,500 hours of continuous 1-sun maximum power point operation at 65 °C.

With promises for high specific energy, high safety and low cost, the all-solid-state lithium–sulfur battery (ASSLSB) is ideal for next-generation energy storage 1 , 2 , 3 , 4 , 5 . However, the poor rate performance and short cycle life caused by the sluggish solid–solid sulfur redox reaction (SSSRR) at the three-phase boundaries remain to be solved. Here we demonstrate a fast SSSRR enabled by lithium thioborophosphate iodide (LBPSI) glass-phase solid electrolytes (GSEs). On the basis of the reversible redox between I − and I 2 /I 3 − , the solid electrolyte (SE)—as well as serving as a superionic conductor—functions as a surficial redox mediator that facilitates the sluggish reactions at the solid–solid two-phase boundaries, thereby substantially increasing the density of active sites. Through this mechanism, the ASSLSB exhibits ultrafast charging capability, showing a high specific capacity of 1,497 mAh g −1 sulfur on charging at 2C (30 °C), while still maintaining 784 mAh g −1 sulfur at 20C. Notably, a specific capacity of 432 mAh g −1 sulfur is achieved on charging at an extreme rate of 150C at 60 °C. Furthermore, the cell demonstrates superior cycling stability over 25,000 cycles with 80.2% capacity retention at 5C (25 °C). We expect that our work on redox-mediated SSSRR will pave the way for developing advanced ASSLSBs that are high energy and safe.

Salicylic acid (SA) is a pivotal phytohormone for plant responses to biotic and abiotic stresses. Plants have evolved two pathways to produce SA: the isochorismate synthase and phenylalanine ammonia lyase (PAL) pathways 1 . Whereas the isochorismate synthase pathway has been fully identified 2 , 3 , 4 , the PAL pathway remains incomplete. Here we report the full characterization of the PAL pathway for SA biosynthesis via functional analysis of rice ( Oryza sativa ) SA-DEFICIENT GENE 1 ( OSD1 ) to OSD4 . The cinnamoyl-coenzyme A (CoA) ligase OSD1 catalyses the conversion of trans -cinnamic acid to cinnamoyl-CoA, which is subsequently transformed to benzoyl-CoA via the β-oxidative pathway in peroxisomes. The resulting benzoyl-CoA is further converted to benzyl benzoate by the peroxisomal benzoyltransferase OSD2. Benzyl benzoate is subsequently hydroxylated to benzyl salicylate by the endoplasmic reticulum membrane-resident cytochrome P450 OSD3, which is ultimately hydrolysed to salicylic acid by the cytoplasmic carboxylesterase OSD4. Evolutionary analyses reveal that the PAL pathway was first assembled before the divergence of gymnosperms and has been conserved in most seed plants. Activation of the PAL pathway in rice significantly enhances salicylic acid levels and plant immunity. Completion of the PAL pathway provides critical insights into the primary salicylic acid biosynthetic pathway across plant species and offers a precise target for modulating crop immunity.

Batteries are an attractive grid energy storage technology, but a reliable battery system with the functionalities required for a grid such as high power capability, high safety and low cost remains elusive. Here, we report a solid electrolyte-based molten lithium battery constructed with a molten lithium anode, a molten Sn–Pb or Bi–Pb alloy cathode and a garnet-type Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) solid electrolyte tube. We show that the assembled Li||LLZTO||Sn–Pb and Li||LLZTO||Bi–Pb cells can stably cycle at an intermediate temperature of 240 °C for about one month at current densities of 50 mA cm −2 and 100 mA cm −2 respectively, with almost no capacity decay and an average Coulombic efficiency of 99.98%. Furthermore, the cells demonstrate high power capability with current densities up to 300 mA cm −2 (90 mW cm −2 ) for Li||LLZTO||Sn–Pb and 500 mA cm −2 (175 mW cm −2 ) for Li||LLZTO||Bi–Pb. Our design offers prospects for grid energy storage with intermediate temperature operations, high safety margin and low capital and maintenance costs.

Metabolites can double as a signaling modality that initiates physiological adaptations. Metabolism, a chemical language encoding biological information, has been recognized as a powerful principle directing inflammatory responses. Cytosolic pH is a regulator of inflammatory response in macrophages. Here, we found that L-malate exerts anti-inflammatory effect via BiP-IRF2BP2 signaling, which is a sensor of cytosolic pH in macrophages. First, L-malate, a TCA intermediate upregulated in pro-inflammatory macrophages, was identified as a potent anti-inflammatory metabolite through initial screening. Subsequent screening with DARTS and MS led to the isolation of L-malate-BiP binding. Further screening through protein‒protein interaction microarrays identified a L-malate-restrained coupling of BiP with IRF2BP2, a known anti-inflammatory protein. Interestingly, pH reduction, which promotes carboxyl protonation of L-malate, facilitates L-malate and carboxylate analogues such as succinate to bind BiP, and disrupt BiP-IRF2BP2 interaction in a carboxyl-dependent manner. Both L-malate and acidification inhibit BiP-IRF2BP2 interaction, and protect IRF2BP2 from BiP-driven degradation in macrophages. Furthermore, both in vitro and in vivo, BiP-IRF2BP2 signal is required for effects of both L-malate and pH on inflammatory responses. These findings reveal a previously unrecognized, proton/carboxylate dual sensing pathway wherein pH and L-malate regulate inflammatory responses, indicating the role of certain carboxylate metabolites as adaptors in the proton biosensing by interactions between macromolecules.

Adhesives are ubiquitous in industries and daily life. However, conventional fossil-derived adhesives pose substantial health and environmental risks during manufacturing and utilization. The development of nontoxic high-performance adhesives from renewable feedstocks is therefore highly desired but remains technically challenging. Here we report a high-performing hot-melt adhesive—glue that is applied in a hot molten state—derived from a byproduct of the pulp industry, xylan, a type of hemicellulose. Under optimal conditions, the lap-shear strength between wood chips can reach approximately 30 MPa, surpassing that of classic epoxy resins and far exceeding that of a commercial hot-melt adhesive (ethylene vinyl acetate). Furthermore, the xylan hot-melt adhesive exhibits excellent reusability for multiple applications, retaining more than 100% of its original adhesion strength even after ten reuse cycles. Toxicity tests show good biocompatibility for xylan hot-melt adhesive. Overall, this work provides useful insights into the design of high-performance, reusable, bio-based adhesives for enhanced sustainability.

Solid-state zinc-ion capacitors are emerging as promising candidates for large-scale energy storage owing to improved safety, mechanical and thermal stability and easy-to-direct stacking. Hydrogel electrolytes are appealing solid-state electrolytes because of eco-friendliness, high conductivity and intrinsic flexibility. However, the electrolyte/electrode interfacial contact and anti-freezing properties of current hydrogel electrolytes are still challenging for practical applications of zinc-ion capacitors. Here, we report a class of hydrogel electrolytes that couple high interfacial adhesion and anti-freezing performance. The synergy of tough hydrogel matrix and chemical anchorage enables a well-adhered interface between hydrogel electrolyte and electrode. Meanwhile, the cooperative solvation of ZnCl 2 and LiCl hybrid salts renders the hydrogel electrolyte high ionic conductivity and mechanical elasticity simultaneously at low temperatures. More significantly, the Zn||carbon nanotubes hybrid capacitor based on this hydrogel electrolyte exhibits low-temperature capacitive performance, delivering high-energy density of 39 Wh kg −1 at −60 °C with capacity retention of 98.7% over 10,000 cycles. With the benefits of the well-adhered electrolyte/electrode interface and the anti-freezing hydrogel electrolyte, the Zn/Li hybrid capacitor is able to accommodate dynamic deformations and function well under 1000 tension cycles even at −60 °C. This work provides a powerful strategy for enabling stable operation of low-temperature zinc-ion capacitors.

The realization of solution-processed tandem quantum-dot LEDs (QLEDs) remains a technical challenge due to the limitations of inefficient interconnect layer and the damage caused by multiple solution processes. Here, we develop a high performance tandem QLED by face-to-face integrating a top-emitting QLED with a transparent QLED. The top and bottom units can be addressed independently, thereby enabling the tandem QLED to operate in series, parallel, and color-tunable modes for multifunctionality. In series mode, QLEDs demonstrate an ultra-low turn-on voltage of 3.3 V and a record-breaking external quantum efficiency of 60.7%. In parallel mode, QLEDs achieve an impressive brightness of over 4.8 × 10 6 cd m -2 . In color-tunable mode, the color, brightness, and color temperature can all be adjusted with a color tuning range of 114% NSTC. Moreover, both series and parallel connections contribute to an improved stability, resulting in a T 95 lifetime of nearly 30,000 h at 1000 cd m -2 , which is an improvement of approximately 2.8 times over control devices. Our work offers a feasible solution for achieving multifunctional tandem QLEDs with the advantages of solution processed, high efficiency, high brightness, long lifetime and full color tunability for various light source applications.

The accumulation of phenolic acid autotoxins is a key factor contributing to the challenges of continuous chili cropping, but efficient and stable remediation methods are currently lacking. This study innovatively employs K₂CO₃ alkali etching to prepare engineered biochar as a laccase carrier, achieving high-efficiency immobilization via glutaraldehyde cross-linking (maximum loading capacity: 177.3 U/g). Compared to free laccase, the immobilized system exhibits significant advantages: broader pH and temperature adaptability, enhanced long-term storage stability, and improved reusability. Experimental results demonstrate that 2 U/mL of immobilized laccase can completely degrade 20 mg/L phthalic acid within 10 h and is effective against multiple chili autotoxic phenolic acids (ferulic acid, cinnamic acid, coumaric acid, and p-hydroxybenzoic acid). After phthalic acid degradation, the solution no longer inhibits chili seed germination, and soil experiments confirm a degradation rate of 51.07% after 11 days. Mechanistic studies reveal that the degradation process relies on synergistic radical and non-radical pathways, with electron transfer playing a dominant role. LC–MS analysis confirms the transformation of phenolic acids into low-toxicity small molecules. This study is the first to propose a biochar-immobilized laccase synergistic degradation strategy, which offers high efficiency, environmental safety, sustainability, and broad applicability compared to existing methods.

Augmented-tactility wearable devices have attracted significant attention for their potential to expand the boundaries of human tactile capabilities and their broad applications in medical rehabilitation. Nonetheless, these devices face challenges in practical applications, including high susceptibility to the operating environments, such as variations in pressure, humidity, and touch speed, as well as concerns regarding wearability and comfort. In this work, we developed an augmented-tactility superskin, termed AtSkin, which integrates a skin-compatible nanofiber sensor array and deep learning algorithms to enhance material recognition regardless of the ambient environment. We fabricated a lightweight and breathable triboelectric sensor array with multilayer nanofiber architectures through electrospinning and hot pressing. The carefully selected combination of sensing layers can capture the electrical characteristics of different materials, thus enabling their distinction. Combined with deep learning algorithms, AtSkin achieved an accuracy of 97.9% in distinguishing visually similar resin and fabric materials, even under varying environmental pressures and humidities. As a proof of concept, we constructed an intelligent augmented-tactility system capable of identifying fabrics with similar textures and hand feel, demonstrating the potential of the superskin to expand human tactile capabilities, enhance augmented reality experiences, and revolutionize intelligent healthcare solutions.
