NASICON (NAtrium Super Ionic CONductor)-structured Na 4 MnCr(PO 4 ) 3 has attracted attention as a promising cathode for sodium-ion batteries due to its high operating voltage and specific capacity contributed by multielectron reactions. Unfortunately, its intrinsic low electronic conductivity significantly hinders the release of specific capacity and rate capability, preventing its practical application. Herein, a carbon layer with dual conductive networks connected by chain-like Ketjen black (KB) is built on the surface of Na 4 MnCr(PO 4 ) 3 material. This novel Na 4 MnCr(PO 4 ) 3 /C@KB composite material exhibits improved rate capability of 61.2 mAh g −1 at 2 C compared to 19.5 mAh g −1 of Na 4 MnCr(PO 4 ) 3 /C and high reversible capacity of 88.0 mAh g −1 at 1 C with 73% capacity retention after 100 cycles. The enhanced electrochemical performance can be ascribed to an increase of electronic conductivity enabled by the dual conductive 3D network construction and an adequate infiltration of electrolyte by substantial pores existence in carbon layer. A promising dual conductive network design strategy is demonstrated here for improving the performance of NASICON-structured cathodes.

The development of rechargeable Mg-based batteries with a high energy density is restricted by the high-voltage cathodes and the parasitic side reactions between the battery components and electrolytes operating at relatively high potentials. Here, we develop a hybrid Mg2+/Li+ cell using a monoclinic or orthorhombic Fe2(MoO4)3 cathode, a Mg anode, and a simple (PhMgCl)2–AlCl3 + LiCl electrolyte. Hastelloy-C alloy is proposed as a current collector of high-voltage cathode for the hybrid Mg2+/Li+ battery within a Swagelok-type cell. The application of the Hastelloy-C alloy current collector breaks the crucial bottleneck of incompatibility between the currently available current collectors and electrolytes. The hybrid cell features a low voltage polarization between the discharge and charge profiles, which is in favor of practical applications. On the other hand, because all Li+ ions are supplied by the electrolyte in a hybrid Mg2+/Li+ battery, a high Li+ concentration is required to operate at high capacities for the hybrid battery. We further show the first-hand evidence about the compensation of Li+ ions by simply soaking the cathode in the hybrid electrolyte. The prelithiation of Li+ ions into monoclinic Fe2(MoO4)3 significantly enhances the cycling stability and reversibility.

Poly(3-hydroxybutyrate) (PHB), a novel biomaterial for energy storage, was converted to butyrates and butanol via a one-step catalytical hydrogenation. High yields of bio-oils (80.5 wt%) were obtained under a typical reaction condition (Pd/C: PHB = 1: 10, 200 °C, 24 h, 1100 r/min). The collected bio-oils contained butyrates (44.06 wt%), butanol (27.37 wt%) and butyric acid with an estimated higher heating value (HHV) of 33.0 MJ/kg. The syngas composed mainly of methane and butane, had an LHV of 65.7 MJ/m 3 , even higher than that of natural gas (38.5 MJ/m 3 ). Under the reaction conditions, the regenerated Pd/C showed almost perfect reusability.

To meet the escalating demands for high-performance piezoelectric materials in fields such as modern medical diagnostics, precision manufacturing, etc., we developed a ternary 0.555Pb(Ni1/3Nb2/3)O3-0.145PbZrO3-0.30PbTiO3 (PNN-PZ-PT) piezoelectric ceramic located at the tricritical point of rhombohedral, tetragonal and pseudocubic phases. This ceramic, with coexistence of multiple ferroelectric phases, demonstrates an ultrahigh piezoelectric coefficient d33 of 1190 picocoulombs per newton (pC/N) and a large relative dielectric constant εr of 9900. Analysis of the domain structure reveals irregular maze-like nanodomains with strong local disorder. These nanodomain structures exhibit excellent local piezoelectric response and polarization switching characteristics, thereby enhancing the alignment of polarization vectors during poling and ensuring the high stability after being poled. The tricritical point composition with disordered nanodomains can significantly enhance the contribution of polarization to macroscopic piezoelectric properties, offering a promising approach for developing ceramics with superior piezoelectricity.

Vision-based robotic triaxial tactile sensing provides superior spatial resolution and rich multimodal data. However, employing rigid CMOS imagers suffers from limitations in mechanical flexibility and large-area scalability. Here we present a large-area ultraflexible photoelectrical impedance tomography (PIT)-based imager that achieves high-fidelity triaxial tactile sensing. The 5-μm-thick PIT imager incorporates a quantum dots/metal-oxide heterojunction layer with 16 peripheral electrodes, significantly reducing interconnects complexity (pixel-to-interconnect ratio >80). The device exhibits a photo-to-dark-current ratio exceeding 10⁴ under ultraviolet illumination, resolves spatiotemporal features as fine as 1.5 mm, and can simultaneously image up to five occluded regions. By integrating a thin light-scattering porous rubber and flexible LEDs, triaxial force decoding is achieved through Gaussian photocurrent analysis. The system achieves over a dynamic range of 80 kPa with a normal force sensitivity of 0.04 kPa⁻¹, a shear displacement resolution of 0.17 μm kPa⁻¹, and a topological recognition accuracy of 96.5%. We anticipate that this technology will enable advanced applications in industrial and humanoid robotics, medical and rehabilitation robotics, and wearable health monitoring and human–machine interaction systems.

Exogenous free radicals oxidize and damage tumor proteins, but their non-specific reactivity also causes unintended harm to tumor-suppressive proteins, which compromises the therapeutic efficacy. Here we show a nanosystem that generates in-situ radical-conjugated species with predefined targeting capability toward oncogenic protein. This nanosystem consists of lipid nanoparticles encapsulating polyphenolic tannic acid and hydrophobic calcium peroxide nanoparticles in spatially segregated compartments. Upon cellular uptake, the components are released into the cellular membrane through membrane fusion. Consequently, calcium peroxide nanoparticles act as oxidizing agents, radicalizing tannic acid, which generates gallic acid species conjugated with phenoxyl radicals. Since gallic acid confers specific binding affinity for the oncogenic GPC-3 protein in hepatocellular carcinoma, the radical-conjugated species integrate dual functionalities: a targeting module that binds to the oncogenic GPC-3 protein, and a stabilized phenoxyl radical inducing site-specific oxidative damage. These species direct to GPC-3 and induce localized disruption of critical peptide segments and lipid domains, triggering protein cleavage and membrane shedding, which suppresses downstream signaling including the canonical Wnt/β-catenin pathway and finally inhibits hepatocellular carcinoma progression. By enabling site-specific radical delivery, this strategy achieves precise inactivation of predefined oncogenic targets and establishes a framework for molecularly free-radical-mediated antitumor therapy.

Hollow SnO 2 nanotubes were prepared via electrospinning and integrated with a simple gas sensor for the detection of hazardous 3-vinylpyridine(3-EP) in environmental settings. Benefiting from the hollow nanotube structure, the sensor provides a large surface area for gas adsorption, significantly enhancing the response value and reducing the operating temperature. At the optimal temperature of 240 °C and a gas concentration of 50 ppm, the response value reaches 21.13. The detection limit is 0.5 ppm, response time, and desorption time are 17 s and 22 s. This study provides a reference for the detection of harmful 3-EP in environmental monitoring.

Highway bridges are primarily reinforced concrete structures. They have multilayer steel mesh sheets, corrugated pipes, and steel strands inside. As a result, detecting defects in bridge concrete structures requires high technical expertise and can be challenging. This article presents a new device of ground-penetrating radar (GPR) designed specifically for highway bridge inspection. It employs antenna array technology, multichannel radar control technology, and real-time 3-D data acquisition and display technology to achieve reliable detection of various concrete structures commonly found in bridges. Using a 1.3 GHz central frequency antenna array and a multichannel control unit, the system enables simultaneous surveying along five lines, the detection depth can exceed 600 mm in concrete. This significantly enhances detection efficiency. By employing specialized software processing, the detection results are presented in a specific and visually comprehensive 3-D format. Moreover, the system provides 3-D slice images from any position and direction, facilitating the interpretation of detection results for various targets, including reinforcement layout, protective layer thickness, corrugated pipes, steel strands, and other quality defects. It provides advanced and reliable technical means for construction quality control and bridge health monitoring of highway bridges. The results indicate that the device performs well not only in controlled experimental environments, but also in real-world bridge structure environments.

We prepared Ti 1.4 V 0.6 Ni ribbons by arc-melting and subsequent melt-spinning techniques. Ti 1.4 V 0.6 Ni + x Mg ( x = 1, 1.5, 2, 2.5 and 3, wt.%) composite alloys were obtained by the mechanical ball-milling method. The structures and hydrogen storage properties of alloys were investigated. Ti 1.4 V 0.6 Ni + x Mg composite alloys contained icosahedral quasicrystalline phase, Ti 2 Ni-type phase, β-Ti solid-solution phase and metallic Mg. The electrochemical and gaseous hydrogen storage properties of alloys were improved with Mg addition. Ti 1.4 V 0.6 Ni + 2 Mg alloy showed maximum electrochemical discharge capacity of 282.5 mAh g −1 as well as copacetic high-rate discharge ability of 82.3% at the discharge current density of 240 mA g −1 compared with that of 30 mA g −1 , and the cycling life achieved above 200 mAh g −1 after 50 consecutive cycles of charging and discharging. The hydrogen absorption/desorption properties of Ti 1.4 V 0.6 Ni + x Mg ( x = 1, 2 and 3, wt.%) alloys were better than Ti 1.4 V 0.6 Ni. Ti 1.4 V 0.6 Ni + 3 Mg alloy also exhibited a favorable hydrogen absorption capacity of 1.53 wt.%. The improvement in the hydrogen storage characteristics caused by adding Mg may be ascribed to better hydrogen diffusion and anti-corrosion ability.

Glycosylated protein nano encapsulation was an efficient encapsulation technology, but its embedding rate for EGCG was not high, and the research on the embedding mechanism was relatively weak. Based on this, this study compared the embedding effect of glycosylated peanut globulin and glycosylated casein on EGCG. The embedding mechanism of EGCG with glycosylated protein was discussed by ultraviolet, fluorescence, infrared and fluorescence microscopy. Results revealed that the highest encapsulation efficiency of EGCG was 93.89 ± 1.11%. The neutral pH value and 0.3 mg/mL EGCG addition amount were suitable for EGCG glycosylated nanocomposites. The hydrogen bond between EGCG hydroxyl group and tyrosine and tryptophan of glycosylated protein is mainly non covalent. The encapsulation effect of EGCG glycosylated nanocomposites could be quenched by changing the polar environment and spatial structure of the group. The fluorescence characteristic and dispersibility of EGCG glycosylated peanut globin were higher than EGCG glycosylated casein. This study might provide a theoretical basis for EGCG microencapsulation technology and EGCG application in tea beverage and liquid tea food systems.

Soil nutrient testing is an effective way to uncover soil nutrient status. However, the conventional testing method (CT method) and Mehlich 3 method (M3 method) demand long-time consumption, tedious testing steps, high testing cost, dangerous chemicals contained in extractant, etc. Therefore, it is important to develop a new rapid test method or improve the existing rapid test method of soil available nutrients. In this study, an improved Mehlich3 method (IM3 method) with the new combined extractant were developed and evaluated on the testing feasibility, precision, efficiency, and cost. The results showed that: (1) IM3 method avoided the usage of two hazardous chemicals, i.e., ammonium nitrate and nitric acid, which were difficult in purchase and storage but contained in the combined extractant of M3 method. (2) The correlation coefficients of available P, K, Fe, Mn, Cu and Zn in calcareous soil between M3 and CT, and between IM3 and CT methods all reached highly significant level. The correlation coefficient of available Zn between IM3 and CT method was significantly higher than that between M3 and CT method, and those of the other elements had not obviously changed. (3) The variation coefficients of available P, K, Fe and Cu determined by M3 and IM3 methods were all lower than those determined by CT method. The variation coefficients of available Mn and Zn determined by IM3 were 3.67% and 6.43%, which were slightly higher than those determined by CT method with 2.72% and 5.29%, but were lower than those determined by M3 method. (4) Under the premise of ensuring testing precision, IM3 method took only 6.3 min/piece for determining six elements, reducing testing time by 70.7% and 3.08% compared with CT (21.5 min/piece) and M3 (6.5 min/piece) methods, respectively. The testing cost of IM3 method was reduced by 26% and 61.2% compared with M3 and CT methods, respectively. In conclusion, IM3 method is an ideal rapid measurement method for the simultaneous determination of available soil nutrients in calcareous soil.Keywords:improved testing method for soil nutrients;extractant;testing precision;testing time;testing cost;calcareous soil

In addition, its electrical conductivity and Seebeck coefficient exceed 3 S/cm and 300 μV/K at 810 K, respectively, with the compound mainly displaying semiconductor properties . In 0.45 Mn 2.17 Bi 3.38 Se 8 exhibits paramagnetism at room temperature followed by a paramagnetic-to-antiferromagnetic transition at ∼10.2 K. Our findings enrich the current understanding of the pavonite homologous series, providing useful insight for future exploration in related fields.
