Developing a secure and unclonable anti-counterfeiting technology with more dimensional encryptions is urgently demanded. All-inorganic halide perovskites hold great potential for applications in advanced fluorescence anti-counterfeiting owing to their superior optical properties, such as tunable emission colors, narrow emission peaks, etc. By further utilizing the feasibility of anion exchange for perovskite halides, this research successfully designs five-dimensional (5D) anti-counterfeiting barcodes with core–shell-like structured perovskite-like oxide and perovskite halide composites. The composites are prepared by a facile synthesis method, which includes adhesive growth of Cs(Pb x Mn 1-x )(Cl y Br 1-y ) 3 on the surface of CsCa 2 Ta 3 O 10 : Yb, Er (abbreviated as CCTO: Yb, Er@CsMX 3 ) via sharing Cs + at the interface. The unique structure makes it possess sensitivity to some additive decrypted inks, offering one more intriguing anti-counterfeiting dimension beyond the common dual-mode fluorescence and time-gating technique. The CCTO: Yb, Er@CsMX 3 composites exhibit typical green upconversion (UC) luminescence under a 980 nm laser, red or green or blue (RGB) emission under ultraviolet (UV) light irradiation, ns-ms emission decay time, and changeable emission color when treated with decrypted inks. The fluorescent inks and barcodes are simple for fabrication, efficient for coding, easy for viewing and difficult for cloning, making them promising for anti-counterfeiting applications.

In the present work, we developed a novel dispersive microextraction technique by combining the advantages of liquid-phase microextraction (LPME) and magnetic solid-phase extraction (MSPE). In this method, trace amount of water directly absorbed on bare Fe 3 O 4 to form water-coated Fe 3 O 4 (W-Fe 3 O 4 ) and rapid extraction can be achieved while W-Fe 3 O 4 dispersed in the sample solution. The analyte adsorbed W-Fe 3 O 4 can be easily collected and isolated from sample solution by application of a magnet. It was worth noting that in the proposed method water was used as extractant and Fe 3 O 4 served as the supporter and retriever of water. The performance of the method was evaluated by extraction of 3-monochloropropane-1,2-diol (3-MCPD) from edible oils. The extracted 3-MCPD was then derived by a silylanization reagent (1-trimethylsilylimidazole) before gas chromatography–mass spectrometry (GC–MS) analysis. Several parameters that affected the extraction and derivatization efficiency were investigated. Our results showed that the limit of detection for 3-MCPD was 1.1 ng/g. The recoveries in spiked oil samples were in the range of 70.0–104.9% with the RSDs less than 5.6% (intra-day) and 6.4% (inter-day). Taken together, the simple, rapid and cost-effective method developed in current study, offers a potential application for the extraction and preconcentration of hydrophilic analytes from complex fatty samples.

With the rapid development of the chemical industry, large amounts of industrial organic pollutants have constituted a huge threat to the ecological environment. The 3-D porous TPU/TiO 2 /PDA composite foam with outstanding oil/water separation and photocatalytic performances was successfully prepared. Its morphology, chemical composition, surface wettability, mechanical properties, oil/water separation, and photocatalytic performances had been systematically studied by SEM, FTIR, XRD, XPS, Raman, XPS, TGA, contact angle instrument, and ultraviolet spectrophotometer. The results showed that TPU/TiO 2 /PDA composite foam can remove water and oil for various oil/water mixtures and emulsion with outstanding separation performance only under the gravitational force. The water and oil separation flux can reach 21,035 L/m 2 ·h and 14,500 L/m 2 ·h, respectively. The highest separation efficiency reach to 99.6% for petroleum ether/water. It also can continuously separate the oil and water from various water/oil mixtures with the assistance of the pump; after 10 cycles, it maintains large separation efficiency of 98.5%. Moreover, the RhB removal rate reached up to 96% only after irradiation 1 h under UV light. These results manifested that the prepared multifunctional TPU/TiO 2 /PDA composite foams have great application prospect in oil/water separation fields, providing a new idea for fabricating 3-D porous composite foams with multifunctionality. A novel type of 3-D porous TPU/TiO 2 /PDA composite foam with multifunctional applications was successfully designed and prepared. It exhibits excellent performance for oil/water separation and photocatalytic degradation of organic dye. Graphical abstract

Currently, the both low electronic and ionic conductivity have seriously hindered the further application of Na 3 V 2 (PO 4 ) 3 (NVP). Nevertheless, traditional carbon materials modification only improves the electronic conductive property, rather than modifying the ionic conductivity. Herein, N-rich carbon resources of glycine (GLY) is introduced to synthesize NVP, which can act as reducing agent and morphology inducer to optimize NVP sample. Notably, GLY supplies favorable N-doped carbon skeleton, and this defective carbon structure benefits for the accelerated electronic conductivity. Besides, porous construction is established after introducing GLY. This unique morphology significantly improves the infiltration effects of electrolyte, thus providing more electrochemical active sites for Na + de-intercalation to improve the ionic conductivity. Meanwhile, porous framework supplies enough space for the shrinkage of crystal cells, so the stress-strain effect is highly restrained, which is demonstrated by Ex-situ XRD. The stabilized crystal and morphological structure of NVP@GLY-2 has been verified by after-cycled XRD/SEM/XPS. Highly improved kinetic characteristics are also investigated by In-situ EIS. Moreover, Accelerating Rate Calorimeter (ARC) measurements indicate that NVP@GLY-2-based half and full cells also have excellent thermal safety properties. Comprehensively, NVP@GLY-2 reveals a high capacity of 119 mAh g −1 at 0.1 C. It reveals 84.5 and 71.2 mAh g −1 at 10 and 50 C, with capacity retention rates of 88.9 % and 85.8 % after 1000 cycles.

In order to explore the corrosion inhibition mechanism of 1-vinyl-3-hexylimidazolium iodide with different concentration for mild steel in 0.5M H 2 SO 4 at 298K, experimental and theoretical studies were carried out. Not only weight loss but also electrochemical experiments reveal that 1-vinyl-3-hexylimidazolium iodide ([VHIM]I) has higher inhibition efficiency. And all experiments have good consistency. The inhibition efficiency was more than 96% comparing with the blank when the concentration was 5mM. It indicates that [VHIM]I adsorbed on the surface of invested metal by forming a film to protect metal. In addition, SEM observation and ATR-IR spectra was used to further confirmed the above. The Langmuir adsorption isotherm was the most proper adsorption model for the adsorption of [VHIM]I molecule on mild steel surface. Moreover, theoretical calculation and molecular dynamic (MD) simulation also manifest that [VHIM]I was absorbed mightily on the metal surface in a parallel mode.

A novel material, sol–gel derived La(OH) 3 nanorods (La(OH) 3 NRs) with excellent film forming ability was prepared, and it was first designed to incorporate with carbon nanotubes (CNTs) to modify glassy carbon electrode (GCE) to simultaneously voltammetric determine ascorbic acid (AA), dopamine (DA), uric acid (UA), and nitrite (NO 2 − ). Cyclic voltammetry (CV), transmission electron microscopy (TEM), and X-ray diffraction (XRD) were employed to characterize the sensor. Under optimal conditions, the linear response range for AA, DA, UA, and NO 2 − were 0.5 μmol L −1 to 1.46 mmol L −1 , 50 nmol L −1 to 35.36 μmol L −1 , 50 nmol L −1 to 0.79 mmol L −1 , and 0.55 μmol L −1 to 0.72 mmol L −1 , respectively and the detection limits were 1.67 μmol L −1 , 1.67 nmol L −1 , 1.67 nmol L −1 , and 0.18 μmol L −1 . The sensor demonstrated well stability, high selectivity and sensitivity. More importance, this material can be extended to construct other electrochemical sensors by the immobilization of enzymes and antibodies.

An electrochemical sensor utilizing Au-Ni@ etched metal-organic framework (etched MOF) on a glassy carbon electrode (GCE) was constructed for ultrasensitive detection of 3-nitrophenol (3-NP). The Au-Ni@etched MOF in situ nanocomposite was synthesized via a simple one-step process that combines the electrochemical etching of Ni-hemin MOF with the simultaneous electrodeposition of Au-Ni bimetallic nanoparticles. The etched MOF not only provides abundant active sites for adsorbing 3-NP, but also serves as a supporter for loading Au-Ni bimetallic nanoparticles. This innovative design endows the electrochemical sensor with exceptional electrocatalytic activity towards 3-NP, achieving a low detection limit of 0.015 μM over the ranges of 0.06 ∼ 10 μM and 10 ∼ 200 μM. Moreover, the electrochemical sensor also shows excellent sensitivity, repeatability, and stability in 3-NP detection. This method offers a highly sensitive electrochemical strategy for accurately assaying 3-NP in water samples and opens new avenues for the application of MOF derivatives in electrochemical platforms.

To reduce dependence on the expensive cofactor and effectively biotransform ethyl 4-chloro-3-oxobutanoate, l -glutamine and glycine were found to enhance the content of intracellular NADH and the reductase activity. Adding the mixture of 200 mM of l -glutamine and 500 mM of glycine to the reaction media, a 1.67-fold of reductase activity was increased over the control without the addition of the two compounds. Moreover, β-cyclodextrin (0.4 mol β-cyclodextrin/mol ethyl 4-chloro-3-oxobutanoate) was also added into this reaction media, and the biocatalytic activity of the whole-cell biocatalyst of Escherichia coli CCZU-K14 was increased by 1.34-fold than that without β-cyclodextrin. In this β-cyclodextrin–water media containing l -glutamine (200 mM) plus glycine (500 mM), ethyl ( S )-4-chloro-3-hydroxybutanoate (>99% ee ) could be obtained from 3000 mM ethyl 4-chloro-3-oxobutanoate in the yield of 98.0% after 8 h. All the positive features demonstrate the potential applicability of the bioprocess for the large-scale production of ethyl ( S )-4-chloro-3-hydroxybutanoate.

Complex perovskite-structured Ba(Zn 1/3 Nb 2/3 )O 3 (BZN) ceramics with high B-site 1:2 ordering degree and excellent dielectric properties were successfully fabricated using digital light processing (DLP). BZN ceramic slurry with 82 wt. % solid loading, low viscosity, and high curing properties was used to prepare green bodies. The samples were exposed to debinding process in vacuum and then sintered at 1350–1450 ℃ for 4 h. The as-sintered BZN ceramics with disordered B-site structure exhibited significantly low dielectric properties. However, the BZN ceramics annealed at 1300 ℃ for 24 h with high B-site 1:2 ordering degree exhibited excellent dielectric properties ( ε r = 38.9, Q × f = 89,600 GHz, and τ f = 22 ppm/℃) that were identical to those of dry-pressed ceramics. Furthermore, a DLP-fabricated cylindrical BZN dielectric resonator antenna exhibited a >90% radiation efficiency and resonant frequency of 7.10 GHz ( S 11 = -29.94 dB), which is consistent with the simulation results.

Our previous study found that 1-(4-bromophenyl)-5-phenyl-1H-1,2,3-triazole (BPT) exhibited very low toxicity and higher biology activity. In the present study, BPT was used to investigate its mechanism against Colletotrichum gloeosporioides in mango by chemical proteomics and chemicobiological methods. The experimental results of some phenotypic traits and cytotoxicity indicated that there are some changes in permeability of the cell membranes and BPT has fungistatic activity with lower cytotoxicity. Next, a biotin probe named BPTN with a higher activity (EC 50 value of 11.08 mg/L) than that of BPT(EC 50 value of 14.13 mg/L) was designed and synthesized by the chemical proteomics approach. The major differentially expressed proteins between BPT or BPTN and Colletotrichum gloeosporioides were identified and analyzed by Matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF-MS) and bioinformatics. The results indicated that there are 25 differentially expressed proteins in Colletotrichum gloeosporioides under BPT intervention, and 29 target proteins in Colletotrichum gloeosporioides captured by BPTN. For BPTN-anthracnose system, the protein No. 8 belonged to cytochrome P450 proteins (CYP) family can be taken as a target protein of BPTN, which confirmed by bioinformatics analysis. Further, a classic fungal target protein of triazoles, sterol 14α-demethylase (CYP51) was used to verify the interaction in the presence of BPT by various spectroscopic and molecular docking methods. The results showed that BPT exhibited strong interactions with CYP51 and it was predominantly driven by hydrophobic forces and hydrogen bonds. The present study has significant theoretical and practical implications for the development of novel 1,2,3-triazole antifungal agents.

Atherosclerosis is a major cause of cardiovascular disease (CVD). The trimethylamine (TMA)-trimethylamine N-oxide (TMAO) pathway is a key crossover pathway highly associated with diet, gut microbiome, and atherosclerosis. The Bifidobacterium animalis subsp. lactis F1-3–2 ( Bif. animalis F1-3–2, No. CCTCCM2020832) was screened through in vitro and in vivo experiments in the early stage of this study with excellent lipid-lowering and anti-inflammatory function. By building an atherosclerosis model and focusing on TMAO, the specific mechanism of Bif. animalis F1-3–2 to improve atherosclerosis was explored. The study found that Bif. animalis F1-3–2 effectively improved the accumulation of aortic plaque in atherosclerotic mice. The strain improved lipid metabolism in serum and liver. It decreased the serum TMA and TMAO, regulated bile acid composition, participated in the farnesoid X receptor (FXR) pathway to improve lipid metabolism, and further reduced the aortic macrophage foam cell accumulation. In addition, the strain could improve the structure of the intestinal microbiome and reduce the proportion of Firmicutes and Bacteroidetes. The abundance of Turicibacter , Clostridium sensu stricto_1 , and Romboutsia was reduced at the genus level. The differential microbiota is highly correlated with bile acid metabolism, which is speculated to be involved in ameliorating atherosclerotic lipid metabolism disorders. Graphical abstract

Heavy rare earth elements (HREEs) have extensive applications in critical industries. Xenotime (YPO 4 ) is an important phosphatic mineral rich in HREEs. The application of 2-hydroxy-3-naphthyl hydroxamic acid (NHA) as a collector in the flotation of xenotime has rarely been been explored previously. This study reveals the effect of NHA on the flotation behavior and adsorption mechanism of xenotime. The high-grade rare earth concentrate with significant recovery is achieved at the optimized flotation conditions. Techniques such as Fourier transform-infrared spectra (FTIR), X-ray photoelectron spectroscopy (XPS), and first-principles calculations were employed to clarify the adsorption mechanism of NHA on xenotime. These studies disclose that chemical adsorption occurs through the interaction between N-bonded and carbonyl O atoms, creating a bidentate bond with an Y 3+ ion on the xenotime surface. These findings underscore the potential of NHA for selective flotation of xenotime, providing valuable insight into xenotime processing.
