The soft rot of sweet cherries caused by Rhizopus stolonifer ( R. stolonifer ) results in significant economic losses during storage and transportation. This study demonstrated that volatile organaic compounds (VOCs) derived from the fermentation broth of Bacillus velezensis ( B. velezensis ) Q-84 significantly inhibited the growth of R. stolonifer by 54.43%. Scanning electron microscope (SEM) micrographs of VOCs-treated fungi revealed antifungal activity, evidenced by the breakage and deformation of the mycelium. Through headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME-GC/MS) analysis, ten VOCs were identified in the fermentation broth of B. velezensis . Notably, 5-methyl-2-heptanone, 2,5-dimethylpyrazine, 2-decanone, and benzaldehyde exhibited significant antifungal activity in vitro . Furthermore, in vivo assays demonstrated the efficacy of both individual and combined VOCs in managing soft rot diseases in cherries. These treatments also resulted in increased levels of total polyphenolic content (TPC) and total flavonoid content (TFC), as well as a significant enhancement in the activities of defense-related enzymes such as peroxidase (POD), polyphenol oxidase (PPO), phenylalanine ammonia-lyase (PAL), and chitinase (CHI). Our results further our understanding of B. velezensis antifungal metabolites on the management of R. stolonifer and may help in finding less toxic compounds to control soft rot on sweet cherries.

Designing promising electrode material for supercapacitor application with rich redox activities, high capacity and great cycling stability has become a research priority. Herein, a nanohybrid (CoS 1.097 -NiS-MoS 2 ) with nanosheets combining nanorods morphology is prepared by high-temperature pyrolysis sulfuration of ZIF-67/NiMoO 4 . Co-existence of multiple crystalline phases is favorable for enriching electrochemical active sites and facilitating electron transfer. Consequently, CoS 1.097 -NiS-MoS 2 displays better supercapacitor performance with a specific capacity of 373.6 C g −1 at current density of 1 A g −1 and excellent cycling stability of 70.01% after 3000 cycles, surpassing CoS 1.097 (49.1 C g −1 ; 59.26%) and NiS-MoS 2 (105.8 C g −1 ; 62.00%). Moreover, a hybrid supercapacitor is assembled with CoS 1.097 -NiS-MoS 2 and activated carbon, exhibiting high energy density of 21.0 Wh kg −1 at 800 W kg −1 .

Inter-layer gliding induced phase transitions are widely recognized as the predominant cause of performance degradation in layered oxide positive electrode materials utilized in Na/Li-ion batteries. However, effectively restraining these phase transitions at a fundamental level poses a significant challenge. In this study, we elucidate that gliding at the X2/Y3 (X, Y = P or O) interphase layer can be thermodynamically inhibited through an energetically driven gliding-inhibition mechanism, by systematic structural analysis and correlated energy calculations. Building upon this insight, we propose interphase engineering as an effective approach to mitigate phase transitions. The resulting P2/P3-Na 0.46 Mn 0.9 Ni 0.1 O 2 material, featuring dense and uniform P2/P3 interphases, exhibits notable enhancements in both cycling stability and rate capability. Detailed structure probing conducted through advanced atomic-level electron microscopy and synchrotron X-ray diffraction corroborates the role of the P2/P3 interphase structure in suppressing gliding and phase transition. Furthermore, the widespread applicability of the X2/Y3 interphase concept is validated through the successful implementation in several other extended X2/Y3 interphase materials. These findings provide further understanding of interphase phenomena and suggest a strategy to suppress phase transition in layered positive electrode materials.

Electrooxidation of pollutants at potentials near or below the thermodynamic hydrogen evolution potential offers transformative opportunities for energy-efficient pollutant valorization and diverse energy devices. However, existing catalysts suffer from rapid deactivation due to the inevitable overoxidation. Herein, we present an amorphous phosphorus-doped CoFe₂O₄ catalyst that achieves industrial-level current densities (1 A cm⁻²) at ultralow potentials (0.06, 0.65, and −0.17 V vs. reversible hydrogen electrode) for hydrazine, sulfion, and borohydride electrooxidation, respectively, along with 400-hour stability at 300 mA cm⁻² in a hydrazine-assisted electrolyzer. Mechanistic studies reveal electron transfer from Co-P ligands to Co-O ligands, which enhances the involvement of Co-O ligands in low-potential electrooxidation while protecting Co-P ligands from overoxidation. Furthermore, more positive charges on Co centers lower the activation barrier for such pollutant electrooxidation. This work opens a paradigm for designing robust electrocatalysts by decoupling catalytic activity from oxidative deactivation.

Integrating stretchable and rigid electric units presents a significant challenge in manufacturing stretchable electronics. Their surface property differences prevented reliable stretching-tolerant connections. Here, we report a universal method to construct stretchable connections based on interfacial covalent reactions. It enables robust and conductive bonding among various soft/rigid electronics through simple surface modification and interfacial reaction. The bonding between SEBS rubber and metals reached stretchability over 250% with interfacial toughness over 200 N/m. The ultrathin connection layer provided conductive pathways, achieving an electrical stretchability of 60% between Au-deposited SEBS and Cu sheets. Connections between liquid metal-based stretchable conductors could withstand more than 10,000 stretching cycles to 60% strain while maintaining their high conductivity. The versatility and stability of this method were further proved by fabricating electronic devices that integrated soft and rigid units, including circuits on papers and a gesture-visualizing glove with LEDs, highlighting the robustness of the stretchable connections.

Poor bonding occurs with resin due to surface inertness of carbon fiber (CF), so CF surfaces were often treated. In some common surface treatments, sizing was a simple and effective modification method. Polyurethane (PU) was used as the main component of sizing agents due to its similar structure to polyamide 6 (PA6). The CF/PA6 composites’ interfacial properties were improved using PU as a sizing agent. Meanwhile, in this paper, glycidol (GLD) was introduced into the PU emulsion so that the epoxy group reacted with the carboxyl group on the acidified CF. After testing, when the content of glycidyl in the sizing agent is 2%, the CF/PA6 composites showed an important improvement in tensile, impact, and flexural strengths, which increased by 49.4%, 94.6%, and 53.2%, respectively. In addition, the effect of modified WPU sizing agents with different GLD contents on the properties of CF/PA6 composites was investigated.

A dual-ligand strategy was employed to construct an electrochemiluminescence (ECL) sensing platform based on dual-ligand Tb-MOF and Ag 3 PO 4 @TCPP for sensitive detection of chloramphenicol (CAP), demonstrating its potential applications in environmental monitoring and food safety. The dual-ligand Tb-MOF can be used as a co-reactant promoter, facilitating the rapid electroreduction of S 2 O 8 2− to generate more oxidative mediator SO 4 •− , thereby enhancing the luminescence efficiency of the luminescent material Ag 3 PO 4 @TCPP. Furthermore, the integration of Ag 3 PO 4 @TCPP emitter could effectively overcome the aggregation-caused quenching (ACQ) effect of TCPP and then increase the luminescence intensity by seven-fold, which was attributed to the efficient electron transfer and energy transfer between Ag 3 PO 4 and TCPP. Additionally, ECL spectra and electron spin resonance (ESR) spectra were utilized to investigate the possible ECL mechanism of the dual-ligand Tb-MOF/Ag 3 PO 4 @TCPP system. As a proof of concept, we successfully established an ECL biosensor for detecting CAP, which displayed a wide linear range (10 −6 ~ 10 −15 M) and low detection limit (8.29 × 10 −16 M), demonstrating practical feasibility. This study introduces a dual-ligand strategy to enhance ECL signals, expands the application scope of dual-ligand lanthanide MOFs, and provides new insights into designing high-performance sensing platforms.

An innovative amine-enriched vertically-ordered mesoporous silica film (VMSF) on indium tin oxide (ITO) electrodes (A-VMSF/ITO) utilizing an anionic template strategy was successfully developed, resulting in the inner walls of the nanochannel being adorned with well-ordered and abundant tertiary amine groups. In the context of A-VMSF/ITO, the elevated solution conductivity not only facilitates the permeation of Ru(bpy) 3 2+ within nanochannels by compressing the inner electric double layer (EDL), but also greatly improves the electron-transfer efficiency that is critical for enhanced electrochemiluminescence (ECL) generation. Therefore, the A-VMSF/ITO platform exhibited a consistent increase in ECL intensity with rising ionic strength. This property was subsequently employed for monitoring Escherichia coli ( E. coli ) metabolism, as the metabolic byproducts result in alterations in solution conductivity. Experimental results demonstrated that the ECL signal had closed relationships with the process of E. coli growth, which can be used to evaluate the inhibitory effects of antibiotics. Given its amine-enriched characteristics, A-VMSF/ITO is anticipated to serve as an ideal architecture for nanoconfined ECL research, thereby establishing a robust foundation for homogeneous ECL biosensing.

Dimensionally stable paraffin-chitin nanofibers bifunctional composite foams with excellent thermal energy storage performance and promising thermal insulation properties were successfully constructed. Pickering emulsions of paraffin stabilized by chitin nanofibers were first prepared and then assembled with chitin nanofibers to form porous structures after freeze-drying. As a result, the maximum paraffin content in the product can reach 95.3%. Correspondingly, a maximum latent enthalpy value of 197.5 and 197.2 J/g for melting enthalpy and crystallization enthalpy (approximately 91.7 and 92.2% of that of pure paraffin), with the relative retention of 96.2 and 96.7% are achieved, demonstrating its excellent energy storage capacity. The foam can withstand 232 times its weight at a temperature of 180 °C without leakage, proving its excellent high-temperature dimensional stability. The composite foam also exhibits low thermal conductivity (65 mW/m . K) for heat shielding applications. The sustainability, reproducibility, and excellent thermal regulation performances of composite foam give it great application prospects in the field of energy collection and storage.

To achieve ultra-high dye fixation on cellulose fibers in various dyeing and printing techniques, the relationship between dye structure, physical properties, application techniques, and dyeing performances of nine symmetric polyfunctional reactive red dyes (MFB-1 to MFB-9) with different bridging groups was investigated. By altering the structure of the bridging group, the solubility of the nine dyes can be modulated within the range of 100–400 g/L, and their substantivity can be controlled from 20 to 90%. Using the pad dyeing technique, the fixations of MFB-1, MFB-3, and MFB-9 on cotton fabrics reached 97.16%, 96.82%, and 94.30%, respectively. The dyed cotton fabrics exhibited good levelness, with color difference values (Δ E ) of less than 0.6. The dry rubbing fastness was grade 4 or 4–5, the wet rubbing fastness was grade 3 or 3–4, and the wash fastness was grade 4 or 4–5. MFB-2 and MFB-7 had the highest fixations on cotton fabrics using the exhaust dyeing technique, with values of 91.86% and 89.85%, respectively. The Δ E values for the dyed fabrics were 0.635 and 0.555, respectively. The dry rubbing fastness was grade 4, while the wet rubbing fastness was rated at either grade 2–3 or 3. The wash fastness was above grade 4. Additionally, MFB-4, MFB-5, and MFB-6 achieved ultra-high fixations of over 95% on cotton fabrics using both pad dyeing and printing techniques. The Δ E values for the dyed cotton fabrics from the pad dyeing technique ranged between 0.4 and 0.6, while the Δ E values for the printed fabrics were around 0.3. In both techniques, the dry rubbing fastness was grade 4 or 4–5, and the wet rubbing fastness was grade 3 or 3–4, with wash fastness rated at grade 4–5. MFB-8 achieved a fixation of 89.04% on cotton fabrics in cold pad-batch technique. The colored fabrics showed good levelness and color fastness, with a Δ E value of 0.365. The dry rubbing fastness was grade 4, the wet rubbing fastness was grade 3, and the wash fastness was grade 4 or 4–5. The results of the cross-sectional slice of fibers showed that all nine dyes can effectively penetrate the interior of cellulose fibers.

The equation of state of ilmenite (FeTiO 3 ) and geikielite (MgTiO 3 ) have been investigated using in situ synchrotron X-ray diffraction at high pressures up to ~ 21.8 GPa and ~ 23.0 GPa, respectively. No phase transitions were observed within the experimental pressure ranges for both samples. The pressure-volume data were fitted using the third-order Birch-Murnaghan equation of state (EoS), yielding the following results: for FeTiO 3 , the zero-pressure unit-cell volume V 0 = 312.2(1) Å 3 , the zero-pressure bulk modulus K 0 = 165(4) GPa, and its pressure derivative K ′ 0 = 6.6(6); for MgTiO 3 , V 0 = 304.17(8) Å 3 , K 0 = 157(3) GPa, and K ′ 0 = 7.3(4). Additionally, the axial compressional behavior of FeTiO 3 and MgTiO 3 were also fitted with a linearized third-order Birch-Murnaghan EoS. The axial compressibility coefficients for FeTiO 3 along the a- and c- axes are β a = 1.43(4) × 10 − 3 GPa -1 and β c = 3.17(11) × 10 − 3 GPa -1 , respectively, with an anisotropic ratio of β a : β c = 0.45: 1.00, while β a = 1.76 (7) × 10 − 3 GPa -1 and β c = 2.61(7) × 10 − 3 GPa -1 with an anisotropic ratio of β a : β c = 0.67: 1.00 for MgTiO 3 . Both FeTiO 3 and MgTiO 3 exhibit the axial compression anisotropy, of which FeTiO 3 shows stronger axial compressibility anisotropy than MgTiO 3 . Moreover, the potential influencing factors (e.g., cation radius, crystal structure, and chemical bond strength) on the bulk moduli and the anisotropic linear compressibilities of FeTiO 3 and MgTiO 3 were further discussed.

The oxygen evolution reaction (OER), serving as the anode in water electrolysis, plays a pivotal role in various applications. Developing efficient non-iridium-based catalysts for acidic water splitting remains a significant challenge. This study employs a phase engineering strategy to synthesize defect-rich crystalline/amorphous Ru 0.6 Mo 0.2 Cr 0.2 O x solid solution catalysts through dual-metal doping. The catalyst exhibits superior acidic OER performance with an overpotential of 204 mV (@10 mA cm −2 ) and mass activity of 577.8 A g Ru −1 at 1.5 V vs RHE, outperforming all control samples. Furthermore, synergistic Cr/Mo doping effectively reduces the oxidation state of Ru in RuO 2 while enhancing structural stability, resulting in minimal activity decay during prolonged testing. Theoretical calculations reveal that dual-doping synergistically modulates charge distribution on Ru sites, lowering the energy barrier for *OOH formation in the thermodynamic limiting step. This work provides a facile strategy for developing high-performance acidic OER catalysts with dramatically reduced noble metal loading, demonstrating critical industrial relevance.
