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.

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.

NASICON-type Li1.3Al0.3Ti1.7(PO4)3 (LATP) is a widely used solid electrolyte in solid-state lithium batteries, owing to its excellent chemical stability against moisture and high total ionic conductivity. However, traditionally, densification of LATP has been achieved through a high-temperature sintering process (approximately 1000 °C) owing to its poor sinterability. Herein, we report a facile synthesis route to obtain highly sinterable LATP solid electrolyte using tetrabutyl titanate (C16H36O4Ti) as the titanium source and incorporating the traditional solid-state reaction method. The synthetic LATP powder mixed with a low ratio of LiTiPO5 exhibited a hybrid crystalline–amorphous phase structure, which facilitated grain fusion, promoted structural homogeneity, and facilitated structural densification under low-temperature sintering. The sintered LATP pellet, which exhibited an interconnected structure and indistinct grain boundaries, achieved a relative density of >90% and an ionic conductivity of 0.667 mS/cm at a sintering temperature of only 750 °C. Additionally, we systematically studied and demonstrated the synthesis reaction mechanism, sintering behavior, and ionic diffusion kinetics of LATP electrolytes. Our study paves the way for synthesizing highly sinterable LATP solid electrolytes using a simple, additive-free, and cost-effective method.

Secretory glands, responsible for tears and saliva production, play essential roles in maintaining ocular and oral well-being. Disruptions in gland secretion can arise from various factors, including rhythm disturbances associated with sleep disorders. However, the underlying mechanisms governing these disruptions remain largely unexplored. We demonstrate that BMAL1, a core component of the circadian system, plays a critical role in regulating secretory gland secretion. Loss of BMAL1 induces vacuolation and atrophy phenotypes in acinar cells, subsequently leading to cell apoptosis and gland hypofunction, but does not cause Sjogren's syndrome, which is characterized by localized inflammatory cell infiltration. Mechanically, BMAL1 directly modulates the transcription of ITPR2 and ITPR3, thereby altering the secretion of Lactoferrin and Lysozyme. Restoration of ITPR2 and ITPR3 expression in Bmal1 -deficient rats effectively alleviated the symptoms of lacrimal and parotid glands secretory dysfunction and significantly reduced dry mouth and dry eye conditions in rhythm-disordered rats. These findings highlight the essential role of BMAL1 in regulating salivary and lacrimal gland secretion and suggest a novel therapeutic approach for treating dry mouth and dry eyes associated with rhythm disorders.

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.

Enzymatic transformation is an attractive strategy for converting C1 compounds derived from CO2 into high-value products. However, its large-scale application is hampered by the necessity of costly cofactors such as ATP, NADH, and tetrahydrofolate. Here, we designed two costly cofactor-free enzymatic pathways that require only 5 enzymes and chemically synthesized cheap cofactor TPP for the production of platform compounds 3-hydroxypyruvate (3-HP) and pyruvate from formaldehyde. We screened and characterized two key enzymes, dihydroxyacetone oxidase catalyzing dihydroxyacetone oxidation and glyoxalase III catalyzing 3-hydroxypyruvaldehyde isomerization, in the designed pathways. We also engineered glyoxalase III SAV0551 toward stereoselectively isomerizing 3-hydroxypyruvaldehyde into l-glycerate to improve the production of 3-HP from formaldehyde. Then, we combined methanol oxidation with alcohol oxidase and the two designed pathways for enzymatic synthesis of 3-HP and pyruvate from CO2-derived methanol. The final concentrations of 3-HP and pyruvate reached 50.2 and 49.6 mM, with synthesis rates of 7.2 mmol C L–1 h–1 and 5.5 mmol C L–1 h–1, respectively. In addition, by coupling transketolase and pyruvate decarboxylase into the enzymatic system, we also achieved the biosynthesis of d-sedoheptulose-7-phosphate and acetoin from CO2-derived 3-HP and pyruvate with concentrations of 46.9 and 23.6 mM, respectively.

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.

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.
