p-Cu 2 O is one of the most promising p-type semiconductor photocatalysts for the conversion of solar energy into chemical energy. However, the thermodynamically and kinetically permissible self-oxidation reaction of p-Cu 2 O leads to its low photostability, which remains a bottleneck for its practical application in photocatalysis. Herein, we have simultaneously inhibited thermodynamic and kinetic photocorrosion of p-Cu 2 O via constructing an amorphous hole-transfer conformal interface, which can maintain 91 % photocatalytic degradation efficiency at 6 cycles photodegradation of tetracycline (TC). The significantly improved photostability of the p-Cu 2 O is attributed to the formation of amorphous hole-transfer medium with a conformal shell structure on the surface of p-Cu 2 O, which can inhibit the thermodynamic self-oxidation of p-Cu 2 O by avoiding the contact between the photocatalyst and the electrolyte, and kinetically inhibit photocorrosion of p-Cu 2 O via accelerating hole transfer. These results should provide a fundamental solution to the photocorrosion of the photocatalysts, and open new opportunities for the design and development of photostable catalytic system.

DNA formylation (5-formylcytosine, 5fC) is a major epigenetic modification involved in alterations in the DNA double helix structure and protein identification. Due to the low amount in all mammalian tissues and cells, it is necessary to develop a rapid, sensitive and efficient method for detecting 5fC for further understanding the biological functions of 5fC. Thus, a novel PEC biosensor was constructed using P-g-C 3 N 4 -WS 2 nanocomposite as photoactive material. Firstly, AuNPs/P-g-C 3 N 4 -WS 2 /ITO electrode was prepared as substrate electrode. Secondly, the probe DNA and complementary DNA (containing 5fC base) was modified to the electrode surface based on the formation of Au-S bonds between AuNPs and thiol group on the probe DNA and hybridization, respectively. Finally, the amino functionalized MnO 2 nanoflowers were further modified to the electrode surface by covalent interaction between the aldehyde group on the 5fC and the amino group on MnO 2 nanoflowers. The sensitive and specific detection of 5fC can be achieved by oxidizing ascorbic acid with MnO 2 nanoflowers and quenching the photoactivity of P-g-C 3 N 4 -WS 2 nanocomposite. The sensor has a detection range of 0.01–200 nM and a detection limit of 3.8 pM. Moreover, this sensor has excellent detection specificity, stability and reproducibility.

Multidrug resistance (MDR) restricts chemotherapy efficacy due to P-glycoprotein (P-gp) mediated drug efflux, whereas current approaches to suppressing P-gp expression suffer from intrinsic challenges, such as low transfection, high toxicity and poor specificity. Here, hollow ferric-tannic acid complex nanocapsules (HFe-TA), which can be effectively degraded by the reaction with adenosine triphosphate (ATP), are synthesized for the delivery of glucose oxidase (GOx) and doxorubicin (DOX) for tumor treatment. The findings indicate that the intracellular ATP is significantly decreased due to the combined effect of HFe-TA degradation and GOx-mediated glucose consumption. Along with this ATP down-regulation, P-gp expression of tumor cells is suppressed remarkably, which in turn promotes the intracellular accumulation and anticancer efficacy of DOX. In addition, the production of OH by Fe ions released from HFe-TA is promoted by the by-products of the oxidation of glucose process by GOx. In consequence, HFe-TA nanocapsules loaded with DOX and GOx enable significant inhibition effect to tumors both in vitro and in vivo due to the synergistic effect of cascade reactions. This study has therefore provided an alternative therapeutic platform for effective tumor inhibition with the potential in overcoming intrinsic MDR.

Depression, a mood disorder, affects one in fifteen adults, has multiple risk factors and is associated with complicated underlying pathological mechanisms. P-coumaric acid (p-CA), a phenolic acid, is widely distributed in vegetables, fruits and mushrooms. P-CA has demonstrated a protective role against oxidative stress and inflammation in various diseases, including cardiovascular disease, diabetes and cancer. In the current study, we investigated the protection of p-CA against depression and memory impairment in a corticosterone (CORT)-induced chronic depressive mouse model. CORT administration resulted in depression-like behaviors and memory impairment. P-CA treatment alleviated CORT-induced depression-related behaviors and memory impairment. Network pharmacology predicted that p-CA had multiple targets and mediated various signaling pathways, of which inflammation-associated targets and signaling pathways are predominant. Western blotting showed CORT-induced activation of the advanced glycation end product (AGE)-receptor of AGE (RAGE) (AGE-RAGE) signaling and increased expression of the proinflammatory cytokines interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNFα) in the hippocampus, while p-CA treatment inactivated AGE-RAGE signaling and decreased the levels of IL-1β and TNFα, suggesting that protection against depression and memory impairment by p-CA is mediated by the inhibition of inflammation, mainly via the AGE-RAGE signaling pathway. Our data suggest that p-CA treatment will benefit patients with depression.Keywords:depression;p-coumaric acid;inflammation;AGE-RAGE signaling pathway;network pharmacology

The rapid advancement of high-power integrated electronics has generated an urgent demand for high-performance thermal management materials. Hexagonal boron nitride (h-BN) has been widely explored for efficient thermal management. However, voids within the h-BN films compromise their thermal conduction and mechanical performance. Herein, we employed poly(p-phenylene benzobisoxazole) nanofiber (PBONF) as a polymer matrix to bridge unmodified h-BN microsheets. Highly compact nacre-like structures with enhanced interfacial interaction were obtained via a combination of blend exfoliation, filtration self-assembly, hot pressing, and thermal cross-linking. Remarkably, the films containing only 5 wt % PBONF achieved superior thermal conductivity (46.11 W/mK in-plane and 6.53 W/mK through-plane), alongside outstanding mechanical strength, thermal stability, and flame retardancy. These exceptional properties make the composite a promising candidate for application in extreme environments and next-generation thermal management solutions.

The rational design and synthesis of highly efficient electrocatalysts for oxygen evolution reaction (OER) is of critical importance to the large-scale production of hydrogen by water electrolysis. Here, we develop a bimetallic, synergistic, and highly efficient Co–Fe–P electrocatalyst for OER, by selecting a two-dimensional metal–organic framework (MOF) of Co-ZIF-L as the precursor. The Co–Fe–P electrocatalyst features pronounced synergistic effects induced by notable electron transfer from Co to Fe, and a large electrochemical active surface area achieved by organizing the synergistic Co–Fe–P into hierarchical nanosheet arrays with disordered grain boundaries. Such features facilitate the generation of abundant and efficiently exposed Co3+ sites for electrocatalytic OER and thus enable Co–Fe–P to deliver excellent activity (overpotential and Tafel slope as low as 240 mV and 36 mV dec–1, respectively, at a current density of 10 mA cm–2 in 1.0 M KOH solution). The Co–Fe–P electrocatalyst also shows great durability by steadily working for up to 24 h. Our work thus provides new insight into the development of highly efficient electrocatalysts based on nanoscale and/or electronic structure engineering.

Polyphosphazene, as a precursor, was synthesized by ultrasonication using 4,4-diaminodiphenyl ether and hexachlorocyclotriphosphazene (HCCP). It was carbonized and functionalized at high temperature to obtain carboxylic acid functionalized N, P co-doped carbon materials (denoted as NPCs-COOH). The structure of NPCs-COOH was characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-ray diffractometry (XRD), Raman spectrometry (Raman), Thermogravimetric analysis (TG) and N2 adsorption-desorption isotherm (BET). The electrosorption properties were explored under different pH values, applied potentials, initial concentrations and contact time. The optimal pH for electrosorption was 5.0 while the equilibrium time was 30 min. The maximum electrosorption capacity from the experiments towards U(VI) was about 551.46 mg g−1 under the most suitable applied potential of 0.9 V, which was much higher than other carbon materials. Meanwhile, it also showed excellent recyclability with a 23.3% reduction of electrosorption capacity after six cycles. A plausible mechanism of electrosorption was presented using XPS analysis. The results showed the N, P co-doped NPCs-COOH can be used in the electrosorption field to remove U(VI) effectively in solution.

We have synthesized a kind of cyano-substituted oligo( p -phenylene) hybrid materials by Knoevenagel condensation reaction, which can be used as ratiometric relative humidity (RH) sensor. When the RH increased from 5 % to 90 %, the maximum emission peak of C1-3/SG gradually redshifted from 530 nm to 575 nm with the fluorescence changed from green to orange. This phenomenon can be attributed to the water vapor induced aggregation of dyes on the matrix. The non-covalent force between the dyes and the silica gel could be adjusted by altering the structures of the dyes, and the RH sensing property of the final hybrid materials could be further regulated. R2-3/SG hybrid fabricated by R2 with large steric isooctyl groups possessed indiscernible RH sensing properties, while the R1-3/SG without hydrogen bond interactions between dyes and substrate was more susceptible to water vapor. The surface properties and specific surface area of the substrate were critical for RH sensing. RH sensing properties were not presented for the substrates without hydroxyl groups or low specific surface area such as PET or PP fibers. Moreover, we have prepared a kind of C1 loaded paper strips, which exhibited potentially ability in anticounterfeiting application.

Poly( p -dioxanone)-block-polyethylene glycol diblock copolymers functionalized with pyrene moieties (Py-PPDO-b-PEG) at the chain ends of PPDO blocks were synthesized for preparing anisotropic micelles with improved stability. The micellization and crystallization of the copolymers were investigated by nano differential scanning calorimetry (Nano DSC), transmission electron microscopy (TEM), UV–vis spectrophotometery, fluorophotometer, and dynamic light scattering (DLS), respectively. The results indicated that the aggregation of pyrene induced by intermolecular interaction lead to micellization of Py-PPDO-b-PEG at much lower concentrations than those of PPDO-b-PEG copolymers without pyrene moieties. The aggregation of pyrene moieties may also serve as nucleation agent and therefore enhance the crystallization rate of PPDO blocks. Fluorescence measurements by using Nile Red as the fluorescent agent indicated that the micelles of Py-PPDO-b-PEG have high stability and load capacity for hydrophobic molecules.

Application of agricultural waste such as rapeseed meal (RM) is regarded as a sustainable way to improve soil phosphorus (P) availability by direct nutrient supply and stimulation of native phosphate-solubilizing microorganisms (PSMs) in soils. However, exploration of the in situ microbial P solubilizing function in soils remains a challenge. Here, by applying both phenotype-based single-cell Raman with D 2 O labeling (Raman-D 2 O) and genotype-based high-throughput chips targeting carbon, nitrogen and P (CNP) functional genes, the effect of RM application on microbial P solubilization in three typical farmland soils was investigated. The abundances of PSMs increased in two alkaline soils after RM application identified by single-cell Raman D 2 O. RM application reduced the diversity of bacterial communities and increased the abundance of a few bacteria with reported P solubilization function. Genotypic analysis indicated that RM addition generally increased the relative abundance of CNP functional genes. A correlation analysis of the abundance of active PSMs with the abundance of soil microbes or functional genes was carried out to decipher the linkage between the phenotype and genotype of PSMs. Myxococcota and C degradation genes were found to potentially contribute to the enhanced microbial P release following RM application. This work provides important new insights into the in situ function of soil PSMs. It will lead to better harnessing of agricultural waste to mobilize soil legacy P and mitigate the P crisis. Impact statement Stimulation of native soil microorganisms to release soil P stocks is a sustainable means of agricultural production, but faces a major challenge in terms of the deciphering of in situ microbial phosphorus (P) solubilization functions. In this study, single-cell Raman spectroscopy and carbon, nitrogen and P (CNP) functional gene chips were used to reveal the phenotypes and genotypes of microbial P solubilization function in three farmland soils amended with agricultural waste of rapeseed meal (RM). Effects of RM on soil properties, active phosphate-solubilizing bacteria, and CNP functional genes that may contribute to P solubilization were revealed, providing important insights into the use of agricultural waste to improve P utilization efficiency.

A novel pyridine-containing aromatic diamine monomer, 4-phenyl-2,6-bis[3-(4-aminophenoxy)phenyl]pyridine ( m , p -PAPP), was successfully synthesized by a modified Chichibabin reaction of benzaldehyde and a substituted acetophenone, 3-(4-nitrophenoxy)acetophenone ( m , p -NPAP), followed by a reduction of the resulting dinitro compound 4-phenyl-2,6-bis[3-(4-nitrophenoxy)phenyl]pyridine ( m , p -PNPP) with Pd/C and hydrazine monohydrate. The aromatic diamine was employed to synthesize a series of pyridine-containing polyimides (PIs) by polycondensation with various aromatic dianhydrides in N , N -dimethylformamide (DMF) via the conventional two-step method, and further thermal or chemical imidization forming PIs. The inherent viscosities of the resulting poly(amic acid)s and PIs were 0.59–0.73 and 0.56–0.68 dL/g; most of the PIs obtained by chemical imidization were readily soluble in common organic solvents such as DMF, N , N -dimethylacetamide (DMAc), N -methyl-2-pyrrolidone (NMP), tetrahydrofuran (THF), etc. Meanwhile, strong and flexible PI films were obtained, which had good thermal stability, with the glass transition temperature ( T
g ) of 204.5–237.4 °C and the temperature at 10% weight loss of 527.7–552.0 °C in nitrogen atmosphere, as well as outstanding mechanical properties with tensile strengths of 88.6–90.4 MPa, a tensile moduli of 1.04–1.56 GPa, and elongations at break of 7.2–8.7%. The PI films also were found to possess low water uptake of 0.89–0.98%.

Abstract Compared with widely studied lead halide perovskite, copper halide perovskite is toxic-free and combines better stability with comparable photoluminescence quantum yield. Cation doping has proven to be an effective way to manipulate optical and electronic properties of perovskite. Unlike lead halide perovskite able to act as the host of different kinds of dopant, copper halide perovskite acting as host material is still a great challenge. Herein, Mn was successfully doped into Cs \(_3\) Cu \(_2\) I \(_5\) under room temperature via solid-state reaction. In addition to original self-trapped emission of Cs \(_3\) Cu \(_2\) I \(_5\) at 445 nm, Mn dopant introduced characteristic emission at \(\sim \) 550 nm and realized dual color emission tuned by feeding ratio, extending chroma of Cs \(_3\) Cu \(_2\) I \(_5\) in blue region. Meanwhile, ultraviolet photo-electron spectra results confirmed that Mn \(^{2+}\) ion replacing Cu \(^+\) resulted in p-type doping in Cs \(_3\) Cu \(_2\) I \(_5\) . The as-prepared Mn:Cs \(_3\) Cu \(_2\) I \(_5\) microcrystals show excellent stability with almost unchanged PL intensity within 15 days. Graphical abstract
