Amide compounds are widely present in drug molecules and natural products, which can be synthesized by acid–amine condensation. It is urgent to design new photocatalysts for achieving both nitroaromatic reduction and C–H oxidation to obtain raw materials, carboxylic acids, and aromatic amines. Herein, a novel isopolymolybdate–incorporated photoactive metal–organic framework, NiMo12–TPT, was constructed by combining the oxidation catalyst [Mo12O40]8–, Ni(II) cation, and photosensitive ligand 2,4,6-tri(4-pyridyl)-1,3,5-triazine (TPT). In the structure, the superior electron storage capacity of [Mo12O40]8–, with its multiple metal centers containing d-electrons, is conducive to providing electrons for the reduction of nitrobenzenes. The donor–acceptor structure of the TPT facilitates the separation of intramolecular charges. Furthermore, the π···π interactions between the TPT molecules promote the transfer of electrons and enhance the performance of photocatalysis. Under illumination, NiMo12–TPTcan activate the C–H bonds to generate carboxylic acids with excellent selectivity and simultaneously realize the multistep proton–coupled electron transfer (PCET) process for nitroaromatic reduction. Moreover, EPR tests and the quenching experiments indicated that •O2–is the main reactive oxygen species (ROS) in the photocatalytic redox reaction process.

Acupuncture, as a traditional Chinese medical treatment, has garnered increasing attention in recent years in fields such as tumor metabolism, the central nervous system, and the immune microenvironment. This paper aims to explore the fundamental principles, mechanisms, and research status of acupuncture therapy for tumor-related diseases. Firstly, we introduce the basic principles of acupuncture therapy, including the theories of meridians and its theoretical basis in tumor treatment. Secondly, we systematically review the mechanisms of acupuncture therapy for tumor-related diseases, discussing how acupuncture alleviates side effects such as pain, depression, fatigue, and gastrointestinal discomfort caused by conventional treatments through modulation of the immune microenvironment, central nervous system, and endocrine system. Subsequently, we discuss the current research status of acupuncture therapy for tumor-related diseases, as well as the application of current research methods and technologies in elucidating acupuncture mechanisms. Additionally, by combining clinical practice with different types of tumor-related diseases as experimental subjects, we demonstrate the application effectiveness and clinical practice experience of acupuncture in tumor treatment. Finally, a comprehensive assessment of acupuncture therapy for tumor-related diseases is provided, summarizing its limitations and prospecting future directions, including interdisciplinary collaboration and personalized treatment. In conclusion, acupuncture, as a feasible adjunctive therapy, is closely related to the central nervous system and the immune microenvironment, holding potential significant value in tumor treatment.

Dielectric films with ultra-high energy storage density and efficiency are urgently needed due to the energy crisis. Here, we construct novel ferroelectric/dead-layer/superparaelectric (FE/DL/SPE) double-heterojunction capacitors, utilizing interface and dead-layer engineering to achieve outstanding energy storage performance. Bi0.9Sm0.1Fe0.9Co0.05Zn0.05O3(BSFCZ) with large polarization, Ba0.985Na0.015Ti0.95Ni0.05O3(BNTN) with low hysteresis and high breakdown strength (Eb), and artificial Al0.9Ga0.1O3(AGO) with wide band-gap were chosen as the FE, SPE, and DL phases, respectively. Interface engineering enables the BSFCZ/AGO/BNTN films to maintain a high polarization of 55 μC cm−2, while the linear dielectric AGO and SPE BNTN substantially suppresses the remnant polarization. This can be clarified by the evolution of domains in the BSFCZ layer: nanodomains are scaled down to polar clusters, reducing polarization hysteresis while maintaining relatively high polarization. Simultaneously, two opposing intrinsic electric fields are formed to offset a portion of the external electric field, and the low dielectric constant AGO layer bears a significant part of the applied electric field due to electromagnetic boundary conditions. Consequently, the Ebis significantly increased from 4.4 MV cm−1of BSFCZ/BNTN to 5.5 MV cm−1of BSFCZ/AGO/BNTN, resulting in a giant recoverable energy density of 132 J cm−3and a high efficiency of 84 % in BSFCZ/AGO/BNTN films. Moreover, the BSFCZ/AGO/BNTN films excel in temperature stability (RT∼200 °C), fatigue resistance (up to 107cycles), and frequency stability (200 Hz to 20 kHz), alongside an exceptionally rapid discharge rate of 2.6 μs. This innovative approach suggests new possibilities for producing environmentally friendly, large-area, high-performance dielectric capacitors.

Multiferroic devices have attracted renewed attention in applications of photovoltaic devices for their efficient carrier separation driven by internal polarization, magnetization, and above-bandgap generated photovoltages. In this work, Zn2SnO4-based multiferroic Bi6Fe1.6Co0.2Ni0.2Ti3O18/Bi2FeCrO6(BFCNT/BFCO) heterojunction photoelectrodes were fabricated. Structural and optical analyses showed that the bandgap of the spinel Zn2SnO4is ∼3.1 eV while those of Aurivillius-type BFCNT and double-perovskite BFCO are 1.62 and 1.74 eV, respectively. Under the simulated AM 1.5G illumination, the as-prepared photoelectrodes delivered a photoconversion efficiency (η) of 3.40% with a short-circuit current density (Jsc), open-circuit voltage (Voc), and fill factor (FF) of 10.3 mA·cm–2, 0.66 V, and 50.4%, respectively. Analyses of adjustment of an applied electric and magnetic field on photovoltaic properties indicated that both magnetization and polarization of multiferroics can effectively tune the built-in electric field and the transport of charge carriers, providing a new idea for the design of future high-performance multiferroic oxide photovoltaic devices.

Single-phase multiferroic BiFeO3and Bi0.9(La/Nd)0.1FeO3(doped with rare earth ions La3+and Nd3+) films grown on (111)-Pt/Ti/SiO2/Si substrate were prepared via sol-gel method and a subsequent rapid thermal process. The phase composition, microstructure, ferroelectric, dielectric, ferromagnetic properties were investigated, and meanwhile, the in-plane magnetoelectric (ME) coupling effects of the films were reported and studied for the first time in this work. Structural characterization by X-ray diffraction and scanning electron microscopy showed that both BiFeO3and Bi0.9(La/Nd)0.1FeO3exhabited a rhombohedral structure with (111) preferred orientation. The results of the physical properties indicated that the introduction of rare earth ions improved significantly the polarization, magnetization and dielectric properties than the undoped BiFeO3crystals, and it enhanced effectively the in-plane ME coupling (the ME coupling coefficient αEincreased from 0.13 in the pure BiFeO3to 0.21 in Bi0.9La0.1FeO3and 0.34 V/(Oe·cm) in Bi0.9Nd0.1FeO3). The mechanism of these phenomena was investigated systematically.

A redox-active metal–organic framework, Cu(I)-TPT, was synthesized by combination of Cu(I), the halogenoid cyanide group (CN), and redox-active organic bridging ligand 2,4,6-tri(4-pyridyl)-1,3,5-triazine (TPT) into one single framework. Cu(I)-TPTdisplays a two-dimensional (2D) plane structure by 1D −Cu(I)–CN– chains connected with TPT ligands. Cu(I)-TPTexhibits intrinsic semiconductive features with a moderate bandgap energy (1.97 eV). Under irradiation, Cu(I)-TPThas an electrical conductivity of 2 × 10–7S cm–1in the presence of the sacrificial electron donor ethanol under the ambient test conditions, which is owing to the π–π stacking interactions between TPT moieties, the d−π conjugation between the Cu(I) ion and the CN ligands, and the permanent microporosity. Cu(I)-TPTdisplayed highly efficient hole–electron separation and ordered electron transfer, which is beneficial for the photoreduction of nitrobenzene. In addition, Cu(I)-TPTdisplays high efficiency in carboxylic cyclization of alkynol with CO2because it possesses highly decentralized Cu(I) catalytic sites to the active C≡C bond of alkynol and affluent N atoms on the 2D sheets to facilitate the trapping and activation of CO2.
