Au@Pt nanozyme, a bimetallic core–shell structure Au and Pt nanoparticle, has attracted significant attention due to its excellent catalytic activity and stability. Here, we propose that Au@Pt improves glucose tolerance and reduces TG after four weeks administration. The transcriptomic analysis of mouse liver tissues treated with Au@Pt nanozyme showed changes in genes related to glucose and lipid metabolism signaling pathways, including glycolysis/gluconeogenesis, pyruvate metabolism, PPAR signaling, and insulin signaling. Moreover, analysis of fecal samples from mice treated with Au@Pt nanozyme showed significant changes in the abundance of beneficial gut microbiota such as Dubosiella , Parvibacter , Enterorhabdus , Monoglobus , Lachnospiraceae_UCG-008 , Lachnospiraceae_UCG-006 , Lachnospiraceae_UCG-001 , and Christensenellaceae_R-7_group . Combined multi-omics correlation analyses revealed that the modulation of glucose and lipid metabolism by Au@Pt was strongly correlated with changes in hepatic gene expression profiles as well as changes in gut microbial profiles. Overall, our integrated multi-omics analysis demonstrated that Au@Pt nanozyme could modulate glucose and lipid metabolism by regulating the expression of key genes in the liver and altering the composition of gut microbiota, providing new insights into the potential applications of Au@Pt nanozyme in the treatment of metabolic disorder.

Metallic Tin (Sn) is an attractive anode material for aqueous batteries due to its high theoretical capacity, low redox potential and strong corrosion resistance. However, the uneven deposition of Sn and severe interfacial side reactions limit its wide application. Herein, a nanoscale fullerene (C 60 ) coating on a Sn anode has been developed by the physical evaporation deposition technology to eliminate complicated side reactions. This coating improves the homogeneity of the Sn anode surface electric field, and reduces the formation of "dead tin". As a result, the C 60 -coated Sn anode can maintain a low voltage hysteresis cycle for more than 850 h. The aqueous NiO//Sn cell encapsulated by this anode achieves a maximum specific discharge capacity of 79.3 mAh·g −1 at a current density of 1.5 A·g −1 . Moreover, as a proof of concept, we propose an aqueous electrochromic Sn battery, which can realize energy storage and reversibly color switch, yielding favorable optical modulation of about 61.1% at 523 nm. This work has developed a cost-effective and high-reliability interfacial engineering strategy that boosts practical uses of Sn metal electrodes, as well as promotes the application of innovative aqueous rechargeable batteries with electrochromic properties.

Cation solvation is well understood in the bulk solution phase, but knowledge is limited regarding the electrode–electrolyte interface. The process by which cation solvation conforms to the interfacial field to form interphases remains unclear. Here we examine the synergistic effects of external and intramolecular fields on accommodating Li + solvates to the Li-metal anode, leading to dielectric-mediated transfer dynamics on the interface. At charged interfaces, cation–anion pairs arrange in a periodic oscillatory distribution. A low-oscillation amplitude exacerbates the electrolyte decomposition and increases surface impedance. We propose a dielectric protocol that maintains cation–anion coordination with a high oscillation amplitude at the interfaces, addressing these issues. Accordingly, we demonstrate a Li-metal pouch cell with an energy density of 500 Wh kg −1 at the Ah level using an ultra-lean electrolyte (1 g Ah −1 ). Our study offers insights into solid/liquid interfaces that are crucial in advancing battery technologies.

Physalis peruviana is a widely spread plant, and its calyx husk are rich in cellulose and hemicellulose, making it an ideal precursor for preparing supercapacitor electrode materials. The Physalis peruviana calyx husk is an excellent source of activated carbon and has a honeycomb-like epidermis, veins, and basic tissues. Its unique skeleton additionally assists to provide the material a three-dimensional structure. A series of porous carbon materials were synthesized from the calyx husk of Physalis peruviana via KOH as an activator. The variation of micromorphology, structure, and electrochemical properties of PCC-T materials with activation temperature has been investigated. The PCC-800 material prepared at 800 °C has a surface oxygen content of 11.63%, a rich pore structure (micro-meso-macroporous), and a large specific surface area (2703.75 m 2 g −1 ). In 6 M KOH, PCC-800 has a specific capacitance of 349.7 F g −1 at a current density of 0.5 A g −1 in a three-electrode system, and a capacitance retention of 78.9% even with a 40-fold increase in current density. The assembled symmetric supercapacitor achieved an energy density of 8.95 Wh kg −1 (250 W kg −1 ) in 6 M KOH and 17.56 Wh kg −1 (187 W kg −1 ) was obtained in 1 M Na 2 SO 4 electrolyte in a two-electrode system. In addition, the capacitance is reduced by only 1.4% after 6,000 charge–discharge cycles at a current density of 8 A g −1 .

An anomalous enhancement of fluorescence of carbon dots (CDs) was observed via lanthanum (La) doping. La-doped CDs (La-CDs) were prepared through microwave pyrolysis within 4 min. With La 3+ doping, the emission band shifted from blue to green although La 3+ is non-fluorescent. The quantum yield and fluorescence lifetime improved by about 20% and 35%, respectively. All experiment results indicate that La 3+ doping is an effective way to tune fluorescence and improve the performance of CDs. Another unique attribute of La-CDs is high sensitivity to Fe 3+ . The La-CD-based fluorescence probe was established and used for sensitive and selective detection of Fe 3+ with a limit of detection of 91 nmol/L. The proposed fluorescence probe also was successfully employed to visualize intracellular Fe 3+ in live HeLa cells through cell imaging. It was also shown that yttrium exhibited the same fluorescence enhancement effect as La. The results may provide a new route for preparing CDs with special properties.

In this work, Co 3 O 4 -Bi 2 O 3 was successfully synthesized using a microwave-assisted method [Co 3 O 4 -Bi 2 O 3 (MW)] and employed as a peroxymonosulfate (PMS) activator for bisphenol A removal. A reference catalyst was prepared using the same preparation conditions but different heating mode and labeled as Co 3 O 4 -Bi 2 O 3 (CH). The series of Co 3 O 4 -Bi 2 O 3 was characterized using XRD, SEM, and N 2 adsorption to detect their crystallinity, morphology, and surface area, among others. Results indicated that both microwave and calcination significantly affected the characteristic and catalytic activity of the catalyst. Moreover, the microwave-irradiated catalyst calcined at 300 °C showed higher catalytic activity and mineralization percentage for BPA degradation than the conventionally heated catalyst calcined at the same temperature. Microwave temperature and microwave time of the proposed microwave-assisted method were also investigated. Compared with other catalysts, the present catalyst showed considerably superior preparation time and degradation efficiency. This study broadens a new horizon for advanced oxidation process using a PMS activator.

Cerium oxide nanoparticles recently have received extensive attention in biomedical applications due to their excellent anti-oxidation performance. In this study, a simple, mild, and green approach was developed to synthesize cerium-doped carbonaceous nanoparticles (Ce-doped CNPs) using bio-mineralization of bull serum albumin (BSA) as precursor. The resultant Ce-doped CNPs exhibited uniform and ultrasmall morphology with an average size of 14.7 nm. XPS and FTIR results revealed the presence of hydrophilic group on the surface of Ce-doped CNPs, which resulted in excellent dispersity in water. The CCK-8 assay demonstrated that Ce-doped CNPs possessed favorable biocompatibility and negligible cytotoxicity. Using H 2 O 2 -induced reactive oxygen species (ROS) as model, Ce-doped CNPs showed highly hydroxyl radical scavenging capability. Furthermore, flow cytometry and live-dead staining results indicated that Ce-doped CNPs protected cells from H 2 O 2 -induced damage in a dose-dependent effect, which provided a direct evidence for anti-oxidative performance. These findings suggest that Ce-doped CNPs as novel ROS scavengers may provide a potential therapeutic prospect in treating diseases associated with oxidative stress.

Background Oil leakages frequently occur during oil product development and oil transportation. These incidents are a vital factor in water contamination, thus leading to serious environmental destruction. Therefore, superhydrophobic/superoleophilic material is one of the solutions to treat oily wastewater. Results This study aimed to develop a simple, fast and low-cost method to treat oily wastewater by synthesizing a new superhydrophobic/superoleophilic corn straw fiber via conventional impregnation. The corresponding results illustrate that abundant homogeneous silica (SiO 2 ) granules evenly accreted on the surface of the prepared fiber were conducive to high surface roughness. Meanwhile, (Heptadecafluoro-1,1,2,2-tetradecyl) trimethoxysilane, a sort of silane coupling agent, could greatly reduce surface free energy by grafting with SiO 2 particles on the corn straw fiber surface. The obtained superhydrophobic/superoleophilic corn straw fiber exhibited a water contact angle of 152° and an oil contact angle of 0° for various oils, strongly demonstrating its considerable application as an oil absorbent that can be applied for oil cleanup. In addition, the prepared fiber displayed a great chemical stability and environmental durability.
Conclusions Due to its high absorption capacity and absorption efficiency, the prepared fiber has great potential as a new oil absorbent for treatment of oily water.

In this work, a smart strategy that combines three-way high performance liquid chromatography-diode array detection (HPLCDAD) data with second-order calibration method based on alternating trilinear decomposition (ATLD) algorithm was proposed for simultaneous determination of eleven non-steroidal anti-inflammatory drugs (NSAIDs) illegally added into Chinese patent drugs and health products. All target analytes were rapidly eluted out within 14.5 min under a simple gradient elution. With the aid of the prominent “second-order advantage” of the ATLD algorithm, three HPLC problems, i.e. peak overlaps, unknown interferences and baseline drift, could be mathematically calibrated, and pure signals of target analytes could be extracted out from heavy-interference but information-rich HPLC-DAD data. The average spiked recoveries for all target analytes were in the range of 95.9%–106.4% with standard deviations lower than 7.5%. Validation parameters including sensitivity (SEN), selectivity (SEL), limit of detection (LOD), limit of quantitation (LOQ) and precisions of intra-day and inter-day were calculated to validate the accuracy of the proposed method, quantitative results were further confirmed by the classic HPLC method, which proved that chemometrics-assisted HPLC-DAD analytical strategy was highly efficient, accurate and green for drug-abuse monitoring of NSAIDs in Chinese patent drugs and health products.

Copper in drinking water causes a significant environmental problem. Composite material based on alginate hydrogel has been gaining attention in the field of Cu(II) adsorption. However, alginate-based hydrogel exhibits poor mechanical property and relative low adsorption capacity which limit their application. The present study is devoted to the modification of chitosan/calcium alginate/Fe 3 O 4 (CAF) hydrogel microsphere by NaOH solution for enhancement of Cu(II) adsorption. Results reveal that modification of CAF via NaOH solution significantly improves the mechanical strength and Cu 2+ adsorption capacity of pristine materials. FTIR and XRD analysis confirms that CAF and newly prepared materials (NACAF) are successfully prepared. SEM and EDX are employed to analyze the surface morphology and elemental composition, respectively, both before and after their loading with Cu 2+ . XPS study demonstrates adsorption mechanism is based on chelation and ion-exchange. Compressive stress-strain curves demonstrate NACAF has better mechanical performance than CAF. The adsorption kinetics of the two adsorbents follow a pseudo-second-order model. The equilibrium data were best described by Langmuir isotherm model, and the estimated maximum equilibrium sorption capacity, q
m ,is 261.31 mg/g for the NACAF, which is larger than that of CAF (145.39 mg/g). Hence, NACAF shows excellent mechanical strength and high sorption capacity for Cu 2+ . It has great potential for Cu(II) removal in aqueous solutions.

A novel electrochemical chiral sensor was reported for recognizing tryptophan enantiomers based on multi-walled carbon nanotubes functionalized by 3,4,9,10-perylenetetracarboxylic acid binding with the l -lysine (MWCNTs-PTCA-PLL) via electropolymerization. The electrochemical behaviors of the proposed sensors were then characterized by cyclic voltammetry (CV). Differential pulse voltammetries (DPVs) were applied to investigate the stereoselective recognition of tryptophan (Trp) enantiomers. d -Trp and l -Trp showed different responses in DPVs, and a larger selectivity was obtained from d -Trp. pH level and the effect of the incubation time on the chiral recognition were also investigated for optimizing experimental parameters. In addition, the results of analyzing percentage composition revealed this sensor was able to determine the enantiomeric mixtures. The novel strategy with high stability, good sensitivity, and selective characteristics had opened up a new avenue to recognize Trp enantiomers.

A comparison synthesis of 1,2,3-triazoles bearing isoxazole ether was developed between conventional and microwave-assisted heating. Single/double 1,2,3-triazoles bearing isoxazole ether were synthesized by click reaction starting from substituted isoxazolyl alkyne compounds and substituted benzyl azide compounds or neopen-tylglycol diazide in the presence of copper(I) that in-situ generated. Herein, the effect of different catalysts on the yield was researched by conventional method, and the optimal catalyst was selected. The structures of all the synthe-sized compounds were confirmed by MS, FTIR, 1 H and 13 C NMR spectroscopies. Moreover, the crystal structure of 5-{[(1-benzyl-1 H -1,2,3-triazol-4-yl)methoxy]methyl}-3-(4-fluorophenyl)isoxazole( 2 h) was determined.
