All-solid-state lithium batteries for electric vehicles require high specific power, challenged in thick negative electrodes by fragile conducting networks during volume changes and dendrite growth at high currents. We propose an In 0.38 Sn 0.33 Bi 0.29 ternary alloy negative electrode creating a mixed ionic-electronic conducting continuum that overcomes these limitations. The stepwise formation of multiple phases with sufficient mechanical robustness during Li-alloying effectively stabilizes the ionic and electronic conducting percolation by relieving stress concentration and minimizing crack propagation. The unique reversibility of the multiple phase changes during lithiation/delithiation ensures stable cycling performance. The In 0.38 Sn 0.33 Bi 0.29 negative electrode exhibits a high capacity of ~ 724 mAh g −1 and a critical current density of 150 mA cm −2 at 5.0 mAh cm –2 . The In 0.38 Sn 0.33 Bi 0.29 | |LiCoO 2 full cell with industry-level mass loading (6.49 mAh cm –2 ) can retain 87.5% capacity over 1300 cycles at 4.0 C, delivering a jellyroll specific energy of 203.1 Wh kg −1 and 670.6 Wh L −1 at 5.0 C. The fast-charging capability is further validated by large-format pouch cells. The design principles can be extended to other negative electrode designs for solid-state batteries.

Pomegranate peel (PoP) is a valuable by-product rich in phenolic compounds with strong antioxidant potential. This study applied mechanochemical-assisted extraction (MCAE) to recover phenolics efficiently from PoP using eight solid reagents. The extraction parameters were optimized through response surface methodology based on a central composite design. Ultra-performance liquid chromatography coupled with triple time-of-flight mass spectrometry (UPLC-Triple-TOF/MS) tentatively identified twelve major phytochemicals. These phytochemicals include hydrolysable tannins, flavonoids, and phenolic acids. The optimal MCAE conditions were a liquid–solid ratio of 50 mL/g, an extraction temperature of 78 °C, and an extraction time of 67 min. Under these conditions, a total of 12 phytochemicals were identified and the total phenolic content reached 258.09 ± 1.35 mg GAE/g dry weight. The extract exhibited high antioxidant capacity (DPPH of 526.54 ± 13.38 μmol TE/g DW, ABTS of 1315.65 ± 15.16 μmol TE/g DW, FRAP of 798.57 ± 11.30 μmol TE/g DW, and RA of 1353.87 ± 23.43 μmol TE/g DW) and strong inhibitory activity against α-glucosidase and α-amylase. These results demonstrate that MCAE represents an eco-friendly and cost-effective technique for recovering bioactive phenolic compounds from PoP, offering promising applications as natural antioxidants and enzyme inhibitors in functional food formulations, providing new opportunities for the food industries. These findings provide a new strategy for valorizing agricultural by-products into functional ingredients for food applications.

Phenothiazines are new synthetic pollutants that have attracted attention in the present years. In order to remove such novel pollutants, in this paper, novel catalytic composites loaded with iron metals (SFCs) were prepared by high-temperature pyrolysis of sewage sludge for the degradation of novel pollutants of phenothiazines, represented by methylene blue (MB). It was found that among the five SFCs prepared, SFC700, prepared at a pyrolysis temperature of 700 °C, had the best pore structure, the largest specific surface area (452.3 m 2 g −1 ), the richest functional groups (such as carboxyl, hydroxyl, and C = O bonds, etc.), the most Fe 3 O 4 content, which exhibited the best performance. SFC700 composites could remove 99.9% of MB within 60 min, and the optimal initial pH was 11. SFC700 had a certain decolorization stability, and the degradation rate could still be maintained at about 90%. It was presumed that SFC700 played the dual role of adsorption and catalysis.

In light of advancements in 5G/6G technologies, current research on microwave dielectric ceramics is focused on the development of materials characterized by low sintering temperatures and low permittivity, in order to satisfy the requirements of high-frequency low-temperature co-fired ceramic (LTCC) applications. Novel monoclinic structure GdBaK(MoO 4 ) 3 and YBaK(MoO 4 ) 3 ceramics, with C2 / c space group, were synthesized using a conventional solid-state method. GdBaK(MoO 4 ) 3 and YBaK(MoO 4 ) 3 ceramics were sintered at 830 °C and 850 °C, exhibited ε r ~ 8.54 and 8.77, τ f ~ − 51.1 ppm/°C and − 45.8 ppm/°C, Q × f ~ 23, 240 GHz and 59, 277 GHz, respectively. The compression from Ba 2+ and K + cations was identified as the main reason for the higher theoretical ε theo compared to the corrected ε corr . The dielectric loss of both ceramics is mainly affected by the density and packing fraction. The full width at half maximum (FWHM) values of the vibrational peak at 932 cm −1 , corresponding to the symmetric stretching modes of MoO 4 2− , exhibits a negative correlation with the Q × f values. Based on the P–V–L theory, the lattice energy and bond energy associated with the Mo–O bond played a substantial role in influencing the Q × f and τ f . Moreover, YBaK(MoO 4 ) 3 showed good chemical compatibility with Ag, indicating its potential for LTCC applications.

In this work, bionic structure design was introduced to optimize the mechanical properties of ceramics using Si 3 N 4 fibers and BN interfaces. It was shown that Si 3 N 4 f /BN i fibrous monolithic ceramic possessed outstanding fracture toughness with the K IC value of 13.06 MPa·m 1/2 while retaining the flexural strength of 603.59 MPa. This indicated that the BN interfaces extended the crack propagation path and improved the fracture toughness of ceramics. Meanwhile, the densification of ceramics was efficiently promoted by the constant application of pressure starting from room temperature during the sintering process, with a density of up to 3.18 g/cm 3 . An innovative fiber inclusion model was first established to calculate the residual stress, and predict the flexural strength considering residual stress. This work offers new prospects for the synchronous realization of high strength and toughness in Si 3 N 4 ceramics and for predicting the strength of fibrous monolithic ceramics. Graphical abstract

Layered Li-rich Mn-based (LRM) oxides are promising cathode materials for next-generation high-energy batteries. However, their commercialization is hindered by intrinsic structural issues and subsequent degradation processes. In order to address the degradation mechanisms, we use operando neutron diffraction and scanning transmission electron microscopy to follow the microstructural degeneration of the LRM oxides in a prepared full cell with a graphite anode. The methods enable both real-time phase analysis and structural evolution mapping across a wide field of view. The LRM oxide is observed to initially have a partially ordered Li 2 MnO 3 -like structure with multiple planar defects. It transitions from an ordered monoclinic phase to a disordered rhombohedral phase as a result of irreversible Li + migration and transition metal rearrangement during cycling. Especially after the first full charge, the interlayer (001) twining-like structures and local intralayer frustrations formed. Over cycling, the intralayer frustrations further develop into pore-like microstructures along the {012} twinning boundary in the bulk of the particles, which contributes significantly to performance reduction. The results clarify the link between microstructure degradation and performance loss and provide valuable insights into the optimization of high-performance cathodes.

Relaxor ferroelectric ceramics have emerged as promising candidates for electrocaloric cooling systems due to their relatively higher heating and cooling capacities. However, simultaneously achieving high temperature changes (Δ T ) and a wide operating temperature range remains a significant challenge, limiting their practical applications. This work proposes a synergistic strategy that involves precise compositional tuning of the BaTiO 3 - x KNbO 3 system to customize the rhombohedral-to-cubic phase boundary around room temperature, coupled with engineering grain orientation of the ceramics. Based on this approach, a maximum Δ T of 3.9 K is achieved in <111> c -texture BaTiO 3 -KNbO 3 ceramics, outperforming most environmentally friendly ceramics. Notably, the Δ T variation remains within ±10% across a temperature range of 30 °C to 80 °C, demonstrating a promising material for the design and application of electrocaloric cooling devices. This work provides new insights for the design of ceramics with optimized electrocaloric properties, offering significant potential for improving the efficiency and functionality of next-generation cooling technologies and devices.

Efficient upcycling of uranyl from uranyl–containing radioactive organic wastewater is of utmost importance for the sustainable development of nuclear energy. In this work, an indirect electrochemical method to upcycle uranyl from radioactive organic wastewater is proposed. A cost-efficient self-standing polyarylether-based covalent organic framework electrode (PAE-COF-AO@CC) not only acts as an oxygen reduction reaction (ORR) catalyst for hydrogen peroxide (H 2 O 2 ) production, but also provides chelating sites for uranyl ions and nucleation center for the following growth of studtite originating from the reaction between H 2 O 2 and chelated uranyl. It’s clarified that the up-take studtite on PAE-COF-AO@CC electrode could transform to high-pure U 3 O 8 after calcinating the permanently used PAE-COF-AO@CC electrode. The ultra-long lifespan of longer than 450 h and the excellent uranyl capacity of 9238.9 mg/g from the continuous accumulation of studtite make the self-standing PAE-COF-AO@CC electrode as promising materials for the uranyl resource upcycling from the complicated organic waste water matrix.

A solid-state reaction method was successfully employed to synthesize [(Zn 0.8 Mg 0.2 ) 1-x Ni x ] 2 SiO 4 microwave dielectric ceramics by partially substituting [Zn 0.8 Mg 0.2 ] 2+ with Ni 2+ ions. XRD analysis indicated that the proportion of the primary Zn 2 SiO 4 phase decreases with increasing Ni 2+ content, while the secondary MgNi(SiO 4 ) phase becomes predominant. This phase transition contributes to a reduction in dielectric loss. The sintering behavior, phase composition, microstructure, and microwave dielectric properties of the ceramics were systematically investigated. The incorporation of Ni 2+ ions lowered the optimal sintering temperature from 1325 to 1400 °C. SEM analysis revealed that an optimal Ni 2+ substitution level enhanced the grain density within the [(Zn 0.8 Mg 0.2 ) 1-x Ni x ] 2 SiO 4 ceramic matrix. The relationship between Q × f and the average grain size as well as grain uniformity was analyzed. The trend of τ f is primarily governed by the total V izn-o and E zn-o . Additionally, the relationship between lattice vibrations, Raman shifts, and dielectric properties was investigated using Raman spectroscopy. Certainly, the [(Zn 0.8 Mg 0.2 ) 0.8 Ni 0.2 ] 2 SiO 4 ceramic, sintered at 1325 °C, exhibits an exemplary set of microwave dielectric properties: an εr value of 6.8, a Q × f value of 27,185 GHz, and a τ f value of − 37 ppm/ °C.

Responsive synthetic receptors for adaptive recognition of different ionic guests in a competitive environment are valuable molecular tools for not only ion sensing and transport, but also the development of ion-responsive smart materials and related technologies. By virtue of the mechanical chelation and ability to undergo large-amplitude co-conformational changes, described herein is the discovery of a chameleon-like [2]catenane that selectively binds copper(I) or sulfate ions and its associated co-conformational mechanostereochemical switching. This work highlights not only the advantages and versatility of catenane as a molecular skeleton in receptor design, but also its potential in constructing complex responsive systems with multiple inputs and outputs.

Sugarcane ( Saccharum spp.) is a major sucrose and bioenergy crop in the world. The fungal pathogen Sporisorium scitamineum causes sugarcane smut, a devastating disease that destroys stalks and reduces sugar content in sugarcane. This disease can be controlled most effectively by applying smut-resistant sugarcane varieties. Previous studies have shown that Dirigent (DIR ) genes are involved in the synthesis of the lignin precursor pinoresinol, which plays a crucial role in plant resistance to biotic stresses. However, the immune response of the DIR homologs in sugarcane ( ScDIR ) has not been reported yet. In this study, we found that the lignin content of smut-resistant sugarcane varieties (ZZ1, ZZ6, and ZZ9) was significantly higher than that of smut-susceptible varieties (GT42, ROC22, and FN41), and the lignin content of sugarcane increased after smut infection. The smut-resistant and smut-susceptible clones derived from the same genetic population (ROC25 × YZ89-7) showed similar patterns. Quantitative real-time PCR assays revealed that among the 64 DIR genes in sugarcane, ScDIR5 , ScDIR7 , ScDIR11 , and ScDIR40 showed elevated expression after S. scitamineum infection. In vitro coupling reactions showed that the four corresponding ScDIR proteins could mediate the coupling of coniferyl alcohol and its conversion into the lignin precursor pinoresinol. Overexpression of the four ScDIR genes in Nicotiana benthamiana enhanced disease resistance to the fungal pathogens Sclerotium rolfsii , Rhizoctonia solani , and Botrytis cinerea . Moreover, transgenic sugarcane overexpressing these ScDIR genes showed enhanced resistance to smut disease. Taken together, our findings provide evidence that sugarcane ScDIR genes can improve the resistance of plants to fungal pathogens and highlight their potentials in sugarcane breeding for disease resistance.

Background Panax notoginseng saponins (PNS) are commonly used first-line drugs for treating cerebral thrombosis and stroke in China. However, the synchronized and targeted delivery of active ingredients in traditional Chinese medicine (TCM) poses a significant challenge for modern TCM formulations. Methods Bovine serum albumin (BSA) was modified using 2-methacryloyloxyethyl phosphorylcholine (MPC), an analog of acetylcholine, and subsequently adsorbed the major PNS onto the modified albumin to produce MPC-BSA@PNS nanoparticles (NPs). This novel delivery system facilitated efficient and synchronized transport of PNS across the blood–brain barrier (BBB) through active transport mediated by nicotinic acetylcholine receptors. Results In vitro experiments demonstrated that the transport rates of R 1 , R g1 , R b1 , and R d across the BBB were relatively synchronous in MPC-BSA@PNS NPs compared to those in the PNS solution. Additionally, animal experiments revealed that the brain-targeting efficiencies of R 1 + R g1 + R b1 in MPC-BSA@PNS NPs were 2.02 and 7.73 times higher than those in BSA@PNS NPs and the free PNS group, respectively. Conclusions This study presents a simple and feasible approach for achieving the targeted delivery of complex active ingredient clusters in TCM.
