Developing environmentally friendly delivery systems capable of encapsulating, protecting, and promoting the absorption of bioactive components in the human body is crucial for those with low oral bioavailability and poor stability. This study developed W/O/W emulsion-filled sodium alginate (SA) hydrogel for the co-delivery of hydrophilic riboflavin and hydrophobic curcumin. Firstly, W/O/W emulsion was prepared using peanut protein isolate (PPI)-bacterial cellulose nanofibers (BCNFs) as the hydrophilic emulsifier and lecithin as the lipophilic emulsifier, and the effect of stabilizer concentrations on emulsion stability was investigated. Results showed that PPI and BCNFs self-assembled into stable complexes through electrostatic interaction and hydrogen bonding, thereby improving the emulsification properties of PPI. Subsequently, SA was added to the outer aqueous phase of emulsions, and its influence on emulsion properties and stabilization mechanism was investigated. SA significantly improved the stability and rheological properties of PPI-BCNFs-stabilized W/O/W emulsions. Finally, the loading capacity of this system for riboflavin and curcumin and its gastrointestinal fate were evaluated. We found this delivery system efficiently co-delivered both hydrophilic and hydrophobic bioactive components and improved their photostability and thermal stability. Moreover, the bioaccessibilities of riboflavin and curcumin were significantly increased to 61.97% and 45.66%, respectively. This was attributed to SA forming a composite interfacial layer on droplets and a dense gel network in the continuous phase, thereby acting as a physical barrier to better protect the encapsulated components. This delivery system holds promise for the development of functional foods incorporating multiple nutraceuticals.

Catalyst structure manipulation at the atomic level is important in regulating the catalytic performance. Herein, single Cr atom doping in In2O3 is shown to modulate the In–O bond with improved performance in CO2 hydrogenation to methanol. An “asymmetric site effect” concept is proposed to interpret the function of Cr doping, wherein Cr stimulates directly coordinated oxygens to form Cr and In confined oxygen vacancies as active sites for enhancing CO2 activation and lowering the energy barrier of the HCOO* to HCOOH* transformation (the rate-determining step). Meanwhile, Cr assists in maintaining the structure stability and inhibits the over-reduction of In2O3 through tethering nearby oxygen atoms. Cr–In2O3 catalyst exhibits a CO2 conversion of 9.4% and CH3OH selectivity of 92.0% under reaction conditions of 250 °C and 5 MPa, along with a long-term stability over 500 h on-stream testing. This study demonstrates a paradigm for the modulation of In–O in In2O3 to break the trade-off between the reactivity and stability of the CO2 hydrogenation reaction.

Flavonoids, secondary phytometabolites, play many roles in human health and plant resistance, growth, and development. They are commonly glycosylated in the last step of their biosynthesis. In this study, a gene encoding an efficient flavonoid glycosyltransferase, ZmUGT76B1, was cloned from maize and expressed. The enzyme activity and function were characterized. ZmUGT76B1 catalyzed selective glycosylation at 3-, 7-, 3′-, and 4′-hydroxyl sites of flavonoids to form mono-O-glycoside and di-O-glycoside products. Moreover, ZmUGT76B1 had a broad substrate preference and strict sugar donor selectivity. Guided by simulated molecular docking and simulated mutagenesis, three ZmUGT76B1 mutants, Q338P, E361P, and Q338P/E361P, were constructed. The mutation of either of the two sites substantially reduced the enzyme activity, whereas the double mutation eliminated the activity. The determination of enzyme activity and prediction of the active site of this enzyme have expanded our knowledge of maize uridine diphosphate-dependent glycosyltransferases, providing an important glycosyltransferase for metabolic engineering of mono- and dioxygenated glucosyl flavonoids.

Protein glycosylation plays essential roles in various biological processes, and thus determining the glycan structure present on the protein is essential to comprehensively understand these events. However, distinguishing saccharide stereoisomers is challenging, especially when their structures are very similar and their molecular weight and potential glycosylation sites are identical. One representative example is O-linked β-N-acetylglucosamine (O-GlcNAc) and O-linked α-N-acetylgalactosamine (Tn antigen). Traditional biochemistry approaches used in separating O-GlcNAc- and Tn antigen-modified peptides mainly include chemical derivatizations, lectins, and antibodies. However, subsequent mass spectrometry (MS) analysis is still required if one aims to determine the exact glycosylation site. Herein, a straightforward approach using the ratio of relative abundance (RA) of two fragment ions (RA126.055/RA138.055) in higher-energy collisional dissociation (HCD) MS without relying on the traditional biochemistry technique is reported to discriminate between O-GlcNAc and Tn antigen. This ratio was verified by synthetic glycopeptides and proteomic analysis in HeLa cells, where 10 proteins were found to be O-GlcNAcylation and 4 proteins were found to be Tn antigen-modified. Overall, this method can be extensively employed in liquid chromatography–mass spectrometry (LC-MS)-based proteomic studies and thus is of importance in biological and biomedical research.

This study addresses antibiotic water pollution by synthesizing Zr-doped Bi₂₄O₃₁Cl₁₀ (Bi₂₄(₁₋ₓ)Zr₁₈ₓO₃₁Cl₁₀) photocatalysts via hydrothermal method for tetracycline hydrochloride (TC-HCl) removal. Zr doping ratios (6–14%) were systematically investigated, with the optimal BZOC4 (12% Zr) degrading 91.24% of 20 mg/L TC-HCl within 120 min under 500 W xenon lamp irradiation (pH = 9). Its reaction rate constant (0.0239 min −1 ) is triple that of pristine Bi₂₄O₃₁Cl₁₀. Zr doping reduces the band gap from 3.12 eV to 2.8 eV, improves visible light utilization (absorption edge red-shifted to 525 nm), accelerates electron transfer, and reduces e − /h + recombination—supported by UV –Vis DRS, PL, and electrochemical tests. Superoxide radicals (O₂ − ·) and holes (h + ) are primary active species, confirmed by radical trapping and ESR. TOC analysis confirms 32.4% mineralization of TC-HCl to CO₂ and H₂O.This work offers new design strategies for bismuth halide-based photocatalysts in antibiotic remediation by integrating structural regulation and electronic modulation via Zr doping.

A polystyrene-based foam with excellent mechanical properties was prepared. • The synergistic effect of low surface energy and micro-nano rough structure provides excellent anti-adhesion performance against high-temperature oil and water, enabling the material to effectively separate high-temperature emulsions. • The high tortuosity factor of the 3D microporous material ensures high separation efficiency, while the fluid shear force generated under applied pressure effectively expels the demulsified internal phases, thereby ensuring long-term separation of high-temperature emulsions. The separation of water from high-temperature emulsions in real time remains highly challenging due to the potential failure of material wettability. In this study, we develop a thermally stable oleophobic/hydrophobic microporous polystyrene-based foam (FPEI/MoS 2 PS foam) by combining a low-surface-energy fluorinated coating with a micro-nano rough structure. The foam was fabricated via a high internal phase emulsion (HIPE) templating method to construct a 3D microporous structure. Subsequently, MoS 2 was grown on the foam skeleton through a hydrothermal process, followed by the covering of a fluorinated polyethyleneimine (FPEI) functional coating. The resulting foam exhibits a rough microporous structure and thermally stable oleophobic/hydrophobic wettability (WCA and OCA above 128° even at 90 °C). Within a temperature range of 60–90 °C, the material effectively separates surfactant-free emulsions, surfactant-stabilized emulsions, and real industrial emulsions from diesel cracking processes. For W/D ⁎ (surfactant-free water in diesel emulsion), W/D (surfactant-stabilized water in diesel emulsion) and real industrial emulsions at 90 °C, the permeation flux reached 4600, 3050, and 1700 L m −2 h −1 , respectively, with all separation efficiencies exceeded 98%.

Argyrodite sulfide solid electrolytes, such as Li6PS5Cl (LPSC), have received much attention due to their high ionic conductivity (>1 mS cm–1) and success in all-solid-state batteries (long cycle performance, high energy density, etc.). Numerous efforts are spent on modifying the properties of the electrolyte itself. Here, we combine first-principles calculations with experiments to investigate O-doped argyrodite sulfide solid electrolytes (Li6PS5–xClOx,x = 0–1). It is found that Li6PS4.75ClO0.25 (LPSCO0.25) with x = 0.25 and cubic phase (F4̅3 m) shows the highest ion conductivity of 4.7 mS cm–1 (cold-pressed), higher than that of undoped Li6PS5Cl (4.2 mS cm–1). The bare LiCoO2/LPSCO0.25/Li–In all-solid-state battery exhibits an initial capacity of 131 mA h g–1 at 0.1 C and satisfactory cycling stability with 86% capacity retention after 250 cycles to the 4th cycle at 0.3 C under 25 °C. In addition, the NCM811/LPSCO0.25/Li–In cell is assembled using bare LiNi0.83Co0.06Mn0.11O2 cathode and shows an initial discharge capacity of 181 mA h g–1 at 0.1 C and 160 mA h g–1 at 0.3 C. The doping of oxygen-forming Li6PS5–xClOx also improves the stability to Li metal, proven by cyclic voltammetry and powder X-ray diffraction tests. The calculation results for the band structure reveals that LPSC has the lowest unoccupied molecular orbital than LPSCO0.25, further confirming the above conclusion.

The two-dimensional (2D) layered structure of MXene provides a large specific surface area, making it an ideal platform for optimizing geometric configurations in surface-enhanced Raman scattering (SERS) applications. In this study, we developed a novel ternary core-shell nanostructure, Ag@Cu2O-MXene, in which Ag@Cu2O core-shell nanoparticles (NPs) are uniformly anchored onto 2D Ti3C2Tx MXene nanosheets. The Ag NPs exhibit strong localized surface plasmon resonance, while the narrow bandgap and high electron mobility of Cu2O shell promote efficient charge transfer. Importantly, plasmonic coupling between the Ag core and the MXene substrate further enhances plasmon absorption, resulting in a substantial increase in SERS activity and enabling highly sensitive molecular detection. Using this composite, we achieved an ultra-low detection limit of 10–9 M for methylene blue. MXene substrate further facilitates rapid electron transfer from the Ag core to the the Cu2O shell, while its surface defects contribute additional charge carriers to Cu₂O, enhancing the utilization of photogenerated electron. Notably, the SERS enhancement was positively correlated with the thickness of Cu2O shell, highlighting the tunable nature of the Ag@Cu2O-MXene core-shell nanostructure.

The first borate featuring a three-dimensional B–O anionic network with edge-sharing (ES) [BO4] units, Pb2.28Ba1.72B10O19 (PbBaBO), has been synthesized under ambient pressure. The squeezing effect of the 2∞[B10O19] bilayer structure on the intra-layer co-edge [BO4] leads to an extremely long B–B distance and quite small internal O–B–O angles in the [B2O6] ring.

Poly( o -phenylenediamine) was synthesized in different inorganic acid media, hydrochloric (HCl), nitric (HNO 3 ), and phosphoric acid (H 3 PO 4 ).
The aim was to investigate the protective effect of doped coatings on mild steel in an aggressive environment. The synthesized doped-PoPD products were characterized by x-ray diffractometry, Fourier transform infrared spectroscopy, scanning electron microscopy, and cyclic voltammetry. The inhibition abilities of doped coatings were evaluated by potentiodynamic polarization measurements and electrochemical impedance spectroscopy in 3.5% NaCl solution. In the present article, the lowest corrosion current and highest protection efficiency of the doped polymer were observed for the polymer synthesized in HNO 3 medium. The results showed that good protection of mild steel can be achieved by PoPD coating doped with inorganic acid in 3.5% NaCl solution.

The generation, transfer, and collection of plasmon-derived hot electrons represent a distinctive pathway for photodetectors to utilize solar energy. However, previously reported devices have a low internal quantum efficiency due to excessively high Schottky barrier. The coupling distance between working medium and metal nanoparticles (NPs) is one of the key factors affecting the performance of optoelectronic devices. We constructed a dual-surface plasmon-enhanced (Mg, Zn)O-ultraviolet (UV) photodetector by applying Pt NPs and found that the assembled device exhibited broad sensitivity ranging from 340 to 370 nm at room temperature. Intense dual plasmonic resonance coupling is induced in a hybrid structure of two metallic layers separated by uniform ZnO-based films. Using surface plasmon-enhanced materials, the changes in the refractive index of ZnO/Pt/MgZnO and MgZnO/Pt/ZnO heterogeneous double-layer in the dielectric environment are beneficial for the tunneling of hot electrons. ZnO/Pt/MgZnO is superior to MgZnO/Pt/ZnO in terms of responsivity and response time. The responsivity of the ZnO/Pt/MgZnO device peaks at 2.87 A/W, exhibiting the great potential of dual plasmonic resonance coupling in a UV photodetector, which was finally investigated via Mie scattering. The response time of the photodetectors in a steady-state is 0.2 s, 0.3 s, while 0.1 s, 0.73 s is the response time of the photodetectors (PDs), which paves the way for future application advancements in the field of photodetection, imaging, photovoltaics, and photochemistry.

A simple electrochemical sensing method was proposed for fast detection of tyramine in rice vinegar. o -Aminophenol (OAP) was electropolymerized on the surface of glassy carbon electrode (GCE) to form the poly( o -aminophenol) (POAP) film. Then the overoxidized poly( o -aminophenol) film modified GCE (OPOAP/GCE) was obtained by electrochemical treatment of POAP film in the alkaline solution. The modification method of GCE and detection conditions of tyramine were optimized. Electrochemical impedance spectroscopy and scanning electron microscopy were used to characterize the preparation process of OPOAP/GCE and binding ability of tyramine onto the OPOAP film. Furthermore, the electrochemical properties of OPOAP/GCE was investigated by square wave voltammetry. OPOAP/GCE, which was fabricated via cyclic voltammetry in 0.3 M perchloric acid solution with 0.01 M OAP and overoxidized in 0.09 M NaOH solution, showed good electrochemical response on tyramine. The oxidation current and the concentration of tyramine had good linear relationship in the ranges of 0.1-10 μM and 10-200 μM, respectively. The detection limit was 0.054 μM, based on the signal to noise ratio of 3. The recovery rates of tyramine in rice vinegar sample were from 95.6% to 117.2%. The sensor was simple, inexpensive, rapid, and suitable to detect tyramine in rice vinegar sample.
