Complex marine environments (high salinity, humidity, and temperature) accelerate material degradation, urgently demanding durable coatings with integrated thermal stability and corrosion protection. Currently, phenolic epoxy resins are widely used in marine environments for their excellent corrosion resistance, but their long-term durability is insufficient. In this study, phenyltriethoxysilane (PTES), dimethyldiethoxysilane (DEMS), isopropyl titanate (TPT), and boric acid are employed as functional precursors to synthesize a cross-linked titanium-boron-containing organosilicon resin (TBS) via a facile sol-gel process. The resin is subsequently incorporated into a phenolic epoxy resin (EPN) matrix as a functional modifier, constructing a composite protective system of titanium‑boron co-doped organic-inorganic hybrid coatings with synergistically enhanced anticorrosion performance. The results of the electrochemical impedance spectroscopy (EIS) test show that the hybridized coatings exhibits superior anticorrosive performance when the mass fraction of TBS is 50 %. The low-frequency impedance (|Z| 0.01 Hz ) remains above 10 10 Ω·cm 2 after 30 days immersion in 3.5 wt% NaCl solution. In addition, the TBS 1 -EPN 1 coating retains the most intact surface after 7 days of immersion in acid/alkali solutions. Meanwhile, the heat resistance of the coating is optimized, with the initial decomposition temperature increases to 233 °C. This study provides an excellent strategy for designing high-performance anticorrosion coatings for marine hydrothermal areas.

The metallic Ni catalyst suffers from strong binding with the *CO intermediate, resulting in poisoning of the catalyst surface. It is feasible to facilitate the generation of CO by alleviating the binding strength of the *CO intermediate on the Ni metal surface through a lattice expansion strategy. Here, Ni 3 ZnC 0.7 @C with lattice expansion was synthesized by co-doping with Zn and interstitial C through high-temperature pyrolysis. Structural characterization confirms that the lattice of Ni 3 ZnC 0.7 expands by 5.47% compared to Ni due to the co-doping of Zn and interstitial C. The Ni 3 ZnC 0.7 @C possesses excellent catalytic performance with Faradaic efficiency (FE) of CO exceeding 90% over a wide potential range from −0.8 to −1.4 V versus reversible hydrogen electrode (vs. RHE) with a peak FE CO of 96.6% at −1.0 V vs. RHE. In membrane electrode assembly (MEA) testing, Ni 3 ZnC 0.7 @C achieves a FE CO of 81.4% at the industrial-level current density of 400 mA cm −2 . In situ attenuated total reflection surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS) and density functional theory (DFT) calculations reveal that the co-introduction of Zn and interstitial C in the Ni crystal can significantly promote the desorption of *CO intermediate, which facilitates the generation of CO. This study demonstrates a viable way for designing efficient transition metal catalysts for CO 2 electroreduction through lattice strain engineering.

The increasing demand for separation and purification at high temperature emphasizes the importance of thermostable thin-film composite (TFC) nanofiltration (NF) membranes. The performance of the selective layer is profoundly influenced by its molecular structure, and thus the optimization of interfacial polymerization monomers can substantially enhance the thermal stability of the NF membranes. Although some new amine monomers have been reported for the preparation of thermostable TFC membranes, piperazine (PIP) and m-phenylenediamine (MPD) are still the most widely used monomers. In this work, a co-monomer strategy integrating PIP with MPD as the aqueous monomers was employed to improve the rigidity of the polyamide selective layer, thereby fabricating thermostable TFC NF membranes. Precise modulation of PIP/MPD ratios enables effective control over the diffusion rate of aromatic monomers, and hence achieves tunable chemical composition and physical properties. Temperature-dependent pore size analysis and molecular dynamics simulations demonstrated that the incorporation of MPD significantly enhances the thermal stability of the polyamide selective layer. Remarkably, the TFC NF membrane maintains exceptional MgSO4 rejection (>98.5%) across a broad temperature range from 25 °C to 85 °C. This research not only provides fundamental insights into the design of co-monomer systems but also establishes a robust strategy for fabricating thermostable NF membranes.

Despite significant progress in photoelectrochemical (PEC) water splitting, high fabrication costs and limited efficiency of photoanodes hinder practical applications. Bismuth vanadate (BiVO4), with its low cost, non-toxicity, and suitable band structure, is a promising photoanode material but suffers from poor charge transport, sluggish surface kinetics, and photocorrosion. In this study, porous monoclinic BiVO4films are fabricated via a simplified successive ionic layer adsorption and reaction (SILAR) method, followed by borate treatment and PEC deposition of NiFeOx. The resulting B/BiVO4/NiFeOxphotoanode exhibits a significantly enhanced photocurrent density of 2.45 mA cm−2at 1.23 V vs. RHE—5.3 times higher than pristine BiVO4. It also achieves an ABPE of 0.77% and a charge transfer efficiency of 79.5%. These results demonstrate that dual surface modification via borate and NiFeOxis a cost-effective strategy to improve BiVO4-based PEC water splitting performance. This work provides a promising pathway for the scalable development of efficient and economically viable photoanodes for solar hydrogen production.

Platinum-based electrocatalysts represent the most promising candidates for the methanol oxidation reaction (MOR) in direct methanol fuel cells. However, the wide commercialization of platinum-based electrocatalysts faces significant challenges, including high material costs, insufficient catalytic activity, limited operational durability, and susceptibility to CO poisoning. To overcome these issues, a new Au-doped Pt-Co aerogel (AG) is fabricated by the facile one-pot aqueous-solution heteroatom doping method. This catalyst demonstrates good electrocatalytic performance for MOR, combining both high activity and remarkable stability. The Au 1 -Pt 67 Co 33 AG with optimized Au doping amount exhibits outstanding mass activity, which is 1.7 times that of its undoped Pt 67 Co 33 AG counterpart and 4.6 times that of the commercial Pt/C catalyst. Furthermore, the Au 1 -Pt 67 Co 33 AG demonstrates significantly enhanced long-term stability under continuous operation. Density functional theory calculations indicate that Au doping reduces the energy barriers for methanol dehydrogenation and lowers the total energy barriers for the *CO oxidation steps, facilitating the rapid dehydrogenation of CH n OH and faster conversion of *CO, thereby significantly enhancing the electrocatalytic activity and stability of the Au 1 -Pt 67 Co 33 AG toward MOR.

The manganese-based ion sieve H 1.6 Mn 1.6 O 4 shows significant advantages in lithium adsorption. Its prominent features include high adsorption capacity and low pollution characteristics of the preparation process. These combined advantages make this material important in the lithium extraction technology in salt lakes. However, problems such as high manganese dissolution loss rate, poor cyclic stability, and difficulty in powder recycling seriously restrict the industrialized application. In this paper, we propose to optimize the structure of spinel-type manganese lithium ion-sieves with a 2% Co 3+ doping strategy, which can effectively inhibit the lattice collapse triggered by Jahn–Teller aberration during the pickling cycle by replacing part of the Mn 3+ active sites with Co 3+ . After doping, the relative Mn 4+ content on the surface of the material increased from 58%–61% according to the XPS test, confirming that the introduction of Co 3+ facilitated the transition of Mn 3+ to the higher valence state Mn 4+ through the charge compensation effect. Reducing the disproportionation activity of Mn 3+ reduces the dissolution loss of Mn 2+ during the pickling process. The experimental results showed that the adsorption of doped HMCO-2 material increased from 28.8–34.9 mg/g. The adsorption capacity retention rate was 77% after five cycles, there was a high selective adsorption of Li + , and the manganese dissolving loss rate was decreased to 2.3%.

Liver cancer is one of the most prevalent and deadly malignancies worldwide, with limited effective therapeutic strategies. Although doxorubicin (DOX) is widely used as a frontline chemotherapeutic agent, its severe cardiotoxicity and lack of tumor selectivity significantly limited its clinical applications. Polydatin (PLD), a natural antioxidant and anticancer compound, has shown promise as an adjuvant for reducing DOX-induced cardiotoxicity, yet its poor bioavailability hinders its therapeutic potential. To improve the therapeutic efficacy of DOX while reducing systemic toxicity, we developed a hyaluronic acid (HA)-functionalized cubosome-based nanosystem co-loaded with DOX and PLD (1:3 ratio), i.e. HA 3% -D/P-CUBS + , to specifically target tumor sites with enhanced antitumor efficiency and alleviated DOX-induced cardiotoxicity. HA 3% -D/P-CUBS + significantly improved drug internalization and induced apoptosis in hepatocellular carcinoma cells (HepG-2 and HUH-7). Meanwhile, HA 3% -D/P-CUBS + protected normal hepatocytes (HL-7702 and AML-12) and reduced oxidative stress in cardiomyocytes (H9C2 cells). Notably, HA 3% -D/P-CUBS + inhibited in vivo tumor growth of 94 % without causing damage to vital organs, leading to improved survival rates. Moreover, it also mitigated DOX-induced oxidative stress by restoring the balance between oxidative and antioxidant systems. These findings highlight HA 3% -D/P-CUBS + as a promising and synergistic nanomedicine for targeted live cancer therapy, providing new insights into combination chemotherapy with enhanced safety and efficacy.

The design and development of highly efficient, stable, and low-cost electrocatalysts for the oxygen evolution reaction (OER) is crucial for green hydrogen production. Metal–organic frameworks (MOFs), with the merits of structural diversity and tunable organic ligand nature, have significant potential. Herein, a Co-based MOF (CoMnFcMOF) electrocatalyst was fabricated under hydrothermal conditions using Mn as a dopant and a ferrocene-based dicarboxylate linker. The as-prepared CoMnFcMOF enables a current density of 100 mA·cm–2 with an overpotential of 238 mV under an alkaline condition. The well-addressed OER activity is attributed to the spin state modulation of Co induced by Mn incorporation, as verified experimentally and from density functional theory calculations. The total effective magnetic moment (μeff) considerably decreases from 3.992 μB/f.u. in CoFcMOF to 1.974 μB/f.u. in CoMnFcMOF, indicating a spin transition from a high spin (HS) to an intermediate spin (IS) state. This spin modulation facilitates the adsorption of the O* intermediates, thereby accelerating the reaction kinetics. This work establishes a design paradigm for high-performance transition metal-based catalysts through spin state engineering.

The local application of minoxidil tincture has been widely used clinically for the treatment of androgenetic alopecia (AGA). However, there are significant limitations, including ineffectiveness on its own, poor patient compliance, and low transdermal absorption. Microneedles (MNs) can puncture the stratum corneum painlessly and increase drug absorption through the skin. Additionally, nitric oxide (NO) has been shown to improve blood supply to hair follicles and reduce inflammation. Therefore, we prepared a kind of hair-growth-promoting MNs that can co-deliver minoxidil and NO donor for AGA treatment. In simple terms, nanogels (MHMA) were formed through the photopolymerization of methacrylate hyaluronic acid (MeHA) and methacrylate arginine (MeArg) as an NO donor. Through optimized formulation design, minoxidil was efficiently encapsulated within the MHMA nanogels with a particle size of 522.9 nm, which facilitates targeting of hair follicles. Subsequently, the MNs were prepared using a micro-molding method. Both in vitro and in vivo experiments demonstrated that the hair-growth-promoting MNs could efficiently deliver minoxidil and NO donor by just 3 min pressing on the mouse skin. It effectively promoted the transition of hair follicles to the growth phase and stimulated angiogenesis around the follicles, ultimately leading to hair regeneration in the alopecia mouse model. Overall, the proposed hair growth hair-growth-promoting MNs can efficiently and painlessly deliver minoxidil and NO donor into the skin, thus offering a promising new direction for clinical AGA treatment.

Metal organic frameworks (MOFs) have been widely used as microwave absorption (MA) materials owing to their varied structures and large specific surface area. However, it is still challenging to endow MOF derivatives with a rational structure to achieve outstanding microwave absorption. In this work, the hollow Co@C nanorods (HCCN) with lots of winding carbon nanotubes on the surface are obtained based on a template-sacrificing method which employs ZnO nanorods as templates and ZIF67 nanoparticles as ornaments. The HCCNs possess large pore size and specific surface area, efficiently improving the impedance matching . The 1D structure, abundant heterointerfaces and defects trigger strong conduction loss, interfacial and dipole polarization, respectively. Therefore, HCCNs exhibits excellent MA properties: the strong reflection loss of −66.8 dB at the thickness of 2.1 mm and the effective absorption bandwidth of 5.68 GHz at 2.5 mm. Radar cross section (RCS) simulation results have confirmed the practicality of HCCNs. This study proposes an inspiration for the structural designing of MOF materials and derivatives to realize amazing MA performance.

Synthetic drugs fundamentally reshape the illicit drug market due to their low cost, ease of production, and rapid manufacturing processes. However, current drug detection methods, which rely on complex instruments, have limited applicability and often neglect the influence of pH fluctuations, leading to potential bias and unreliable results. Herein, we propose co-calibration DNA probes on a nanoconfined biosensor (N C B S ), covering the range of sweat pH 3–8 to achieve significantly enhanced target signal recognition. The N C B S exhibits a linear response range of 10 3 -10 8 fM with a low limit of detection (LOD) of 3.58 fM in artificial sweat. Compared to the single-aptamer N C B S , the dual-aptamer N C B S offers a broader linear response range, primarily due to the synergistic effects of changes in surface wettability and the capture of hydrion, which together reduce signal interference in proton transport. The linear response range doubles, and its detection sensitivity improves by 4–5 orders of magnitude compared to existing drug detection methods. This sensing strategy expands the application scope of aptamer-based composite probes, offering an approach for ultra-sensitive drug detection and demonstrating significant potential in sweat sensing and drug monitoring fields.

Magnetic metal/porous carbon nanofibers (CNFs) have emerged as a focal point in the study of electromagnetic wave absorbing materials because of their combined electromagnetic losses, multiple scattering, and long attenuation paths. In this work, we prepared porous Co/CNFs using electrospinning integrated with the thermal carbonization process and controlled the porous structure and fiber microwave absorption characteristics by varying the amount of zinc acetate added to the spinning solution. High temperatures led to the volatilization of Zn, creating pores and defects. This process not only increased dipole and interface polarization but also contributed to the reduction of electromagnetic waves (EMWs). When the additive amount of zinc acetate was 0.15 g, the porous Co/carbon nanofibers achieved a smallest reflection loss (RL) of −42.7 dB and an effectively bandwidth (EBW) of 4.48 GHz at a thickness of 2.5 mm. This work provides a new approach for obtaining efficient and lightweight microwave absorbing materials.
