Due to the extensive usage of tetracyclines and fluoroquinolones for disease control, their residuals usually coexist in wastewater and seriously affect human health and the entire ecosystem. To mitigate this problem, developing efficient and recyclable absorbent has been urgently required to be put on the agenda. In this research, Ga-based MOGs (GMOGs) were synthesized to remove chlortetracycline hydrochloride (CTC) and ciprofloxacin hydrochloride (CIP) in aqueous solution, followed by incorporating GMOGs into low-cost sodium alginate (SA) matrix to gain GMOG/SA beads with enhanced adsorption property, fine recycling performance and stable reusability. In single system (S-system), the adsorption behaviors of CTC/CIP by GMOGs and GMOG/SA beads including key operating factors, kinetics, isotherms and practicability were investigated systematically, and the maximum adsorption capacities for CTC/CIP by GMOGs and GMOG/SA beads achieved 406.50/158.23 mg g −1 and 1085.19/862.07 mg g −1 , respectively. Furthermore, the proposed adsorption mechanisms were discussed. In binary system (B-system), regardless of suppressed co-adsorption behaviors of CTC/CIP by GMOGs and GMOG/SA beads arising from the competitive effect between CTC and CIP, their adsorption capacities still reached 207.90/126.90 mg g −1 and 588.24/571.42 mg g −1 , respectively. Moreover, the value of industrial application was evaluated by testing the adsorption performance of GMOG/SA beads in bead columns and real water. This work provides a potential practicable, effective and recycled exploration of GMOG/SA beads for remediating the CTC and CIP co-contaminated wastewater.

Al and Ga were co-doped into ZnO lattice (AGZ) by the sol–gel method. Herein, graphite carbon nitride (g-C 3 N 4 ) was synthesized by using the thermal decomposition method, which was used to integrate with the obtained AGZ to create direct Z-scheme Al/Ga co-doping biphasic ZnO/g-C 3 N 4 heterojunction by the simple single-phase dispersion method. The synthesized catalysts of composition, optical properties, topography structure and chemical state of element of the prepared AGZ/g-C 3 N 4 composites were analyzed by XRD, FT-IR, UV, PL, TEM and XPS respectively. The results have shown that the combination of AGZ and g-C 3 N 4 to form a direct Z-type heterojunction can effectively reduce the band gap of AGZ, thereby shifting the absorption edge to the visible light region. The PL spectroscopy study of the synthesized sample found that, compared with bare g-C 3 N 4 or AGZ catalyst, AGZ/g-C 3 N 4 significantly reduced the recombination of photogenerated electrons and holes, thereby ensuring that more reactive groups participate in the dye degradation process. The degradation experiment of methylene blue(MB) dye verifies that the AGZ/CN sample has excellent photocatalytic performance. Al/Ga co-doped ZnO/g-C 3 N 4 catalyst showed the maximum photocatalytic MB degradation of 95.4% after 150 min in visible light illumination, while the degradation efficiency of ZnO and g-C 3 N 4 are only 30.5% and 50.1%, respectively. It have observed that ·O 2 − , ·OH and h + radicals were the main active species that affect the photocatalytic degradation of dyes by radical trapping experiment. In addition, the heterojunction formed by AGZ and g-C 3 N 4 inhibited the photocorrosion of ZnO, which was confirmed by these five consecutive dye degradation tests. At the same time, in order to determine the optimal compounding ratio, four groups of AGZ/CN with different ratios were prepared. It was found that AGZ/CN15 has the highest catalytic efficiency, and the degradation of MB reached 94% within 2.5 h. This work will open up a new path for the development of more effective photocatalysts for organic matter treatment.

Herein, we developed a novel biodegradable gene carrier for rapid endothelialization of endothelial cells (ECs) in vitro. Three triblock amphiphilic copolymers, methoxy-poly(ethylene glycol)-block-poly(3(S)-methyl-2,5-morpholinedione-co-glycolide)-graft-polyethyleneimine (mPEG-b-P(MMD-co-GA)-g-PEI) with different 3(S)-methyl-2,5-morpholinedione and glycolide contents were synthesized. Microparticles (MPs) were obtained via self-assembly of these copolymers. The hydrophobic core composed of P(MMD-co-GA) segments provide crosslinking points for numbers of PEG and short PEI chains to form a highly hydrophilic and positively charged corona/shell of MPs. Using these MPs, potential genes (ZNF580) for rapid endothelialization were efficiently transported into EA.hy926 cells. Because of the hydrophilic PEG chains and low molecular weight PEI in the triblock copolymers, the cytotoxicity of these MPs and their complexes with pEGFP–ZNF580 was decreased significantly. The transfection efficacy of MPs/pEGFP–ZNF580 complexes was as high as Lipofectamine™ 2000 reagent to EA.hy926 cells in vitro. The proliferation and migration of EA.hy926 cells were improved greatly by the expression of pEGFP–ZNF580 after 60 hours. Our results indicated that the mPEG-b-P(MMD-co-GA)-g-PEI based MPs could be a suitable non-viral gene carrier for ZNF580 gene to enhance rapid endothelialization.

A novel method for extracting polyphenols from Moringa oleifera Lam. ( M. oleifera ) using natural deep eutectic solvents (NADES) has been developed, with extraction conditions optimized via an artificial neural network-genetic algorithm (ANN-GA) to maximize efficiency. Traditional extraction methods for polyphenols from M. oleifera leaves, such as ethanol extraction, are often associated with low efficiency, environmental concerns, and high operational costs. Furthermore, the empirical selection of solvents and extraction conditions is time-consuming and lacks precision. In this study, 28 NADES were employed to predict the solubility of polyphenol molecules through a conductor-like screening model for realistic solvents (COSMO-RS) model. Based on the results, eight highly effective NADES combinations were selected and experimentally verified. The betaine-maleic acid (Bet-MA) combination with the ultrasonic-assisted extraction showed the highest extraction rate of M. oleifera leaves polyphenol (MOLP), which was 1.56 times that of ultrasonic-assisted ethanol solvent. Simplex centroid mixture design (SCMD) and two-level factor experiments were conducted to optimize the ratio of betaine, maleic acid, and water and identify the most influential extraction factors on MOLP yield. The ANN-GA model was further applied to refine the extraction conditions and analyze their interactions on MOLP content. Additionally, antioxidant assays demonstrated that MOLP extracted with the Bet-MA solvent displayed significant antioxidant activity. In conclusion, this study demonstrates that COSMO-RS and ANN-GA may serve as powerful tools for solvent selection and extraction process optimization, offering a green and efficient approach for polyphenol extraction from M. oleifera leaves. The findings highlight the potential of NADES-based extraction methods for broader applications in the extraction of various bioactive substances, contributing to the development of sustainable and environmentally friendly extraction technologies.

Abstract Hierarchically ZSM-5 zeolite was prepared by alkali treatment. It was used as a support for a series of Co-based catalysts for Fischer–Tropsch synthesis with Fe, Ti, Ga or Zn as promoter. This series of catalysts were named Co/M-ZSM-5 (M = Fe, Ti, Ga or Zn). The catalysts were characterized by SEM, XRD, H 2 -TPR, and XPS, and the FTS catalytic performance of catalysts were compared. The character date revealed that the promoter changed the dispersion, reducibility and stability of Co. The addition of Zn and Ga increased the activity of catalysts, decreased the selectivity to CH 4 . The Ti promoted catalyst had the highest initial activity, but it deactivated rapidly. The suitable interaction between Co and the Fe-ZSM-5 result in the suitable dispersion and reduction. Thus Fe is the better promoter for the catalyst Co/ZSM-5. Graphical Abstract

Exploration of new iodates is crucial due to their splendid applications in the nonlinear optical (NLO) field. Two new IIIA metal iodate–selenates, namely, [M(OH)2]3(IO3)(SeO4)·H2O (M = Ga and In), have been successfully synthesized using the hexagonal tungsten oxide (HTO) framework as an ideal structural template. Isostructural [M(OH)2]3(IO3)(SeO4)·H2O (M = Ga and In) crystallize in the polar space group P63mc. Their structures feature ∞[MO2(OH)2]3− (M = Ga, In) layers composed of corner-shared circular M3O6(OH)9 trimeric units based on MO2(OH)4 octahedra. The SeO4 groups are capped above half of the trimeric units of the layers while the IO3 groups are capped below the remaining trimeric units of the layers. Both compounds exhibit moderate phase-matchable second-harmonic generation (SHG) responses (2.9× and 3.8× KH2PO4) under 1064 nm laser radiation and the same band gap of 3.38 eV. Results of theoretical calculations revealed that their SHG effects originated from the synergistic effect of MO6, IO3 and SeO4 groups. So far reports on iodate–selenates are scarce and this work provides a new perspective to design new NLO materials through polar HTO-type topologies and a mixed-anionic strategy.

Ga and F co-doped ZnO (GFZO) thin films were prepared on quartz substrates via the sol-gel spin-coating method, followed by annealing in O 2 , Ar, N 2 , and H 2 atmosphere. The effects of annealing atmosphere on the structure, optical transmission, electrical properties, and thermal stability of GFZO films were systematically investigated. All GFZO films exhibited a typical wurtzite structure with a c-axis preferential orientation. The average optical transmittance of GFZO films annealed in Ar, N 2 , and O 2 atmospheres exceeded 90% in the visible region, while that of the H 2 -annealed sample was about 60%. The resistivity values of GFZO films annealed in Ar, N 2 , and H 2 atmospheres ranged from 1×10 -3 to 3×10 -3 Ω·cm at room temperature, whereas the film annealed in O 2 showed a much higher resistivity of 7.887×10 5 Ω·cm. Notably, the GFZO thin films annealed in Ar or N 2 atmosphere can maintain a low resistivity of 8×10 -3 Ω·cm even at 500 °C while retaining excellent thermal stability. With high optical transmittance, low electrical resistivity, and outstanding thermal stability, the Ar and N 2 annealed GFZO thin films are highly suitable for transparent conductive thin film applications.

Luminescence pressure sensors, valued for their remote sensing capability and high resolution, have been developed recently. However, most current sensors rely on a linear relationship between an optical property and pressure. We propose a nonlinear machine learning (ML) method to model the luminescence intensity ratio (LIR) as a function of pressure. The versatility and performance of this method are demonstrated using (Y,Gd)(Al,Ga) 3 (BO 3 ) 4 :Cr 3+ phosphors as luminescent pressure sensors. The relative sensitivities of the 2 E → 4 A 2 / 4 T 2 → 4 A 2 LIRs in (Y,Gd)(Al,Ga) 3 (BO 3 ) 4 :Cr 3+ range from 1.58%/GPa to 25.27%/GPa. The ML fitting demonstrates a superior performance compared to linear fitting, with lower mean absolute errors (0.0355–0.1499 GPa vs. 0.1209–0.6955 GPa) and higher R 2 values (99.70–99.98% vs. 93.69–99.79%). The ML fitting method is more suitable for modeling the nonlinear relationships between LIR and pressure than traditional linear fitting. The nonlinear ML fitting approach offers a powerful new way to model the relationships between luminescence features and various physical parameters.

Nasicon-type Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) is a potential electrolyte for lithium-ion batteries due to its appropriate conductivity and good air stability. Herein, LATP was co-doped with Ga and Si to improve its ionic conductivity. The Li 1.325 Al 0.29 Ga 0.01 Ti 1.7 Si 0.025 P 2.975 O 12 (LAGTSP025) electrolyte exhibits an ionic conductivity of 8.92 × 10 −4 S/cm at 30 °C, which is mainly ascribed to its enlarged crystal lattice and high densification. This electrolyte material was incorporated into poly(ethylene oxide) (PEO) polymer to form a polymer-based PEO-LITFSI-LAGTSP025 solid composite electrolyte (SCE). The optimized SCE shows a high ionic conductivity of 5.33 × 10 −4 S/cm and excellent interfacial stability at 60 °C. Consequently, a Li/SCE/Li symmetric battery can stably cycle for 1600 cycles at a current density of 0.1 mA/cm 2 . Moreover, an LFP/SCE/Li all-solid-state lithium-ion battery (ASSLIB) maintains a discharge capacity of 143.56 mAh/g and exhibits 95.21% capacity retention after 300 cycles at 0.5C. This work demonstrates PEO-LITFSI-7.5LAGTSP025 SCE is a potential solid electrolyte for ASSLIBs.

Indium tin oxide (ITO) is usually served as the transparent conductive electrode of Cu(In, Ga)(S, -Se) 2 (CIGSSe) solar cells. However, ITO is fabricated by sputtering method, which will increase the cost of CIGSSe solar cells and prevent its large-scale market applications in the future. Hence, it is particularly important to develop low-cost transparent conductive window layers to replace the traditional ITO. Silver nanowires (AgNWs) are considered to be the most promising alternative to ITO. Compared with sputtered ITO, AgNWs have the advantages of high transmittance, low cost, and easy fabrication. Nevertheless, the poor adhesion and stability of AgNWs can prevent the transportation of carriers of CIGSSe solar cells. Here, we select amorphous TiO x as an adjuvant to fabricate AgNWs/TiO x composite transparent conductive layer to substitute the traditional ITO. Under the assistance of TiO x matrix, not only the connection, adhesion, and stability of AgNWs are greatly enhanced, but also the surface roughness of AgNWs is also reduced. The influence of AgNWs concentration on the performance of CIGSSe solar cells is investigated. When the AgNWs concentration is 2.5 mg/mL, the transmittance and sheet resistance of AgNWs thin film are 93.35% and 93 Ω/sq, respectively, and the devices achieved the highest efficiency of 13.59%.

In this study, an Al-0.08Sn-0.08Ga-0.5Mg alloy was annealed at 200 °C–400 °C for 10 h. The microstructure and corrosion morphology of the Al anode were observed by scanning electron microscopy (SEM), and the effects of different annealing temperatures on the electrochemical properties of the Al anodes were studied by the hydrogen evolution rate, open circuit potential, Tafel curves, EIS and constant current discharge. The results show that the annealing treatment had a certain effect on the number and size of precipitates on the alloy surface, which improved the electrochemical activity and corrosion resistance of the Al alloy. Additionally, the Al–Sn–Ga–Mg alloy anode material has an excellent discharge performance in the actual use process when the annealing temperature is 350 °C, the related performance parameters were greatly improved compared with other annealing temperature conditions. The capacity density is 2670.99 mAh·g−1, and the energy density is 3379.15 mWh·g−1.

Achieving acidic seawater hydrogen production under commercial current densities remains a challenge. We present here a novel strategy through strong metal-support interaction (SMSI) and Pt-p-block alloys (PtM@CNT, M = Ga, In, Pb, and Bi) to construct a stable electronic perturbation and achieve acidic seawater hydrogen evolution performance at commercial current densities for the first time. SMSI stabilizes electronic perturbation and promotes durability up to 360 h. The optimized Pt 61 Ga 39 @CNT exhibits an overpotential of 18 mV at 10 mA cm −2 in 0.5 M H 2 SO 4 and maintains 360 h stability at 500 mA cm −2 in acidic seawater. Density functional theory (DFT) calculation reveals that the optimized d -band center of Pt and ΔG H* increase the catalytic activity, and the higher vacancy formation energy enhances the durability. Overall, this discovery not only first achieves stable acidic seawater hydrogen production under commercial current densities, but also opens a new opportunity to explore catalytic applications of p-block alloys and SMSI stabilized electronic perturbation.
