Improved capability to inhibit degradation of trianionic curcumin has been realized in this study. The interaction between trianionic curcumin (Cur 3− ) and gemini dodecyl or tetradecyl O -glucoside micelles , tetradecyltrimethylammonium chloride (TTAC) or hexadecyltrimethylammonium bromide (CTAB) micelles as well as gemini alkyl O -glucosides (AGs)/alkyl trimethyl ammonium halides mixed micelles have been characterized. It is demonstrated that Cur 3− cannot be incorporated into gemini AGs micelles since the lack of electrostatic attraction and degraded as rapidly as in aqueous phase. Cur 3− tend to reside at palisade layer − water interface of TTAC or CTAB micelles due to the strong electrostatic interaction while moderate electrostatic interaction allows Cur 3− to locate more deeply in the palisade layer of mixed micelles. Additionally, mixed micelles tend to form a more compact and hydrophobic palisade layer than pure TTAC and CTAB ones. These factors bring about enhanced fluorescence intensity and blue − shift of emission maxima, improved fluorescence anisotropy and quantum yield, as well as reduced decay rate of Cur 3− in mixed micelles than in pure TTAC and CTAB ones.

Ternary transition metal oxides (TMOs) are potentially promising anode materials for lithium storage with high power and energy density. Designing appropriate electrode structures is an effective strategy to sufficiently exhibit the advantages of TMOs for lithium storage. Here, we present the synthetic process and electrochemical properties of carbon-coated mesoporous Ni–Mn–Co–O (NMCO) nanowire arrays (NWAs) grown on Ni foam as an integrated electrode for lithium-ion batteries (LIBs). The electrochemical measurements show that the carbon-coated NMCO integrated electrode exhibits high capacity and cycling properties. In addition, we have also developed an all one-dimensional (1D) structural full cell using an LiMn2O4 nanorod cathode and an NMCO/Ni NWAs@C-550 anode, which exhibits relatively outstanding cycling properties.

Heteroatom-doped porous carbon has attracted enormous attention in fabricating high-performance supercapacitors . However, designing heteroatoms containing carbon materials through an eco-friendly and cost-effective route remains challenging. In this work, N-O-S self-doped porous carbon materials are prepared from semi-coking wastewater-based phenolic resin (SWPR) via a simple Na 2 CO 3 activation strategy. The abundant phenols , NH 4 + , and SO 4 2- in semi-coking wastewater endows the versatile N, O, and S doping in porous carbon material, remarkably enhancing its conductivity. The optimal SWPR-700–2.5 porous carbon material is obtained at an activation temperature of 700 °C and a mass ratio of 2.5:1 for SWPR: Na 2 CO 3 . The symmetrical supercapacitor is assembled with SWPR-700–2.5, exhibiting a high specific capacitance of 170.5 F g −1 at 0.5 A g −1 , with a high energy density of 5.92 Wh kg −1 at 124.9 W kg −1 . After 10,000 cycles, the Coulombic efficiency and capacity retention are 100% and 99.4%, respectively, at a current density of 20 A g −1 . The excellent performance of SWPR-700–2.5 based capacitor is attributed to the porous structure with a large specific surface area (718 m 2 g −1 ) and abundant N-O-S self-doping (2.739 at% N, 8.627 at% O and 1.378 at% S). This study provides a simple route to prepare N-O-S self-doped porous carbon for supercapacitors and pushes forward the advancement of semi-coking wastewater treatment.

A novel precursor was synthesized by reacting hafnium chloride with dicyandiamide and dimethylformamide. The precursor was characterized via FT-IR and NMR , as well as TG. Subsequently, the precursor was annealed in Ar over a range of temperatures from 1000 °C to 2000 °C, and the microstructural evolution of the ceramics was investigated by XRD , XPS , and TEM. The results show that the carbothermal reduction of the precursor starts at 1150 °C and the ceramic yields at 1500 °C reach 44.6 wt%. The obtained powders exhibit a uniform distribution and are composed of N-doped HfC and graphite. The N-doped structure postponed the oxidation of the HfC(N) ceramics. The HfC(N) ceramics were first oxidized to yield HfO 2 , carbon, and nitrogen, and then the carbon was oxidized with the evolution of CO 2 . The presented synthesis method is believed to be applicable to the preparation of other high-performance ceramics.

Titanium dioxide (TiO2) has been widely studied because of its stable chemical properties, low cost and non-toxicity. But some of its shortcomings also limit its development, such as a large band gap and weak catalytic ability under visible light. The photocatalytic performance of titanium dioxide has been improved by doping nonmetal boron (B) and noble metal rhodium (Rh) in the current study. In general, a metal's electron-deficient state can be regarded as the active sites in a hydrogen evolution reaction. The electron-deficient state of Rhδ+ contributes to its high ability to grab electrons. The light absorption range of Rh nanoparticles (NPs) can reach the visible light band. TiO2 with special morphology is synthesized by a one-step hydrothermal method, and B-doped titanium dioxide with an oxygen vacancy is obtained by adding a B source into the precursor solution. The influence of nonmetal ion doping on oxygen vacancy is studied. The Rh/B–TiO2-550 photocatalyst is synthesized by depositing Rh NPs onto B–TiO2, and the bifunctional photocatalyst with a visible light response is successfully prepared. The Rh/B–TiO2-550 catalyst shows good performance in the degradation of hydrogen and pollutants produced in the photocatalytic decomposition process. Under the irradiation of a 300 W xenon lamp, the hydrogen production reaches 108.67 μmol in 3 h, and the degradation effect of OPP reaches 99.48%.

Electrochromic supercapacitors (ECSCs) find extensive applications in flexible wearable, self-powered smart windows because of their visual energy storage characteristics. ECSCs simultaneously achieve rapid response, high transmittance and high specific capacity. Due to O, S heterocycle with more electron cloud which will bring more electroactive properties, two monomers and a series of polyamides (PAs) films containing furan, thiophene blocks (named as PA1, PA2, PA3, PA4, PA5 and PA6) are designed and synthesized. All the six PAs demonstrate a colorless to dark green/dark blue, while PA2 shows an initial optical contrast of 86 %, bleaching time (t b ) and coloring time (t c ) of 0.9 s and 1.2 s. Simultaneously PA2 delivers a specific capacitance of 197.2F g −1 at a current density of 1 A g −1 . When the current density rises to 20 A g -1 from 1 A g −1 , its capacitance retention rate remains at 79 % of its initial capacitance after undergoing 3000 charge–discharge cycles. ECSCs with PA1, PA2 assembled exhibit a ΔT of 70 % and 76 %. The ECSCs have a specific capacitance (60.1F g −1 and 69.1F g −1 at 1 A g −1 ), with 70 %, 69 % of initial specific capacitance following 2000 consecutive charge–discharge cycles. These PAs containing O, S heterocycle cores demonstrate promising prospect for ECSCs.

Ruthenium oxide is among the most active electrocatalysts for the acidic oxygen evolution reaction (OER), yet its practical use is severely limited by anodic over-oxidation, lattice-oxygen participation, and the resulting Ru dissolution. Here, we report a monolithic RuO 2 -TiO x /Ti anode directly constructed on Ti felt through a one-step impregnation-calcination strategy, in which the native surface oxide evolves at only 400 °C into a rutile-like TiO x interlayer that is lattice-matched with rutile RuO 2 . The resulting structurally defined RuO 2 -TiO x heterointerface induces interfacial charge redistribution and tensile lattice distortion, thereby modulating the Ru–O coordination environment, attenuating Ru–O covalency, and suppressing excessive lattice-oxygen participation. Operando spectroscopy, isotope-labeling analysis, electrochemical probing, and theoretical calculations collectively reveal that such interfacial regulation shifts acidic OER toward the adsorbate-evolution mechanism while suppressing Ru overoxidation and local structural reconstruction. Beyond active-site modulation, the integrated TiO x interlayer and metallic Ti scaffold provide robust interfacial adhesion, efficient electron transport, and favorable gas/liquid transport under high-rate operation. As a result, RuO 2 -TiO x /Ti delivers an overpotential of 172 mV at 10 mA cm −2 , sustains 50 mA cm −2 for 1000 h with only 18 ppb Ru dissolution, and enables proton exchange membrane (PEM) water electrolysis at 1.65 V at 1 A cm −2 . This work highlights lattice-matched heterointerface engineering as an effective strategy for durable acidic OER electrodes. The lattice-matched RuO 2 -TiO x heterointerface induces charge redistribution and tensile distortion, elongating Ru–O bonds, reducing covalency, and suppressing lattice-oxygen participation for highly active and durable acidic oxygen evolution reaction (OER).

Rational microstructure design and compositional regulation have emerged as effective pathways to enhance electromagnetic wave (EMW) absorption, However, simultaneously achieving strong absorption, broad bandwidth, thin thickness and low filler loading remains challenging. Herein, three-dimensional hierarchical heterostructures comprising amorphous carbon-wrapped magnetite supported on flower-like reduced graphene oxide (Fe₃O₄@C/FRGO) was constructed through spray-drying assembly, spatially confined solvothermal crystallization, and defect-modulated carbonization. By tailoring the reduction degree of FRGO and tuning ferrite composition through thermal treatment, the dielectric-magnetic properties and interfacial interactions are precisely regulated. With merely ≈ 3.26 wt% incorporation of FRGO, the optimized composite exhibits a minimum reflection loss (RL min ) of -66.29 dB at 1.94 mm (20 wt% filler) and a broad effective absorption bandwidth (EAB) of 6.60 GHz (11.30–17.90 GHz) at 2.73 mm (30 wt% filler). This exceptional performance is attributed to the engineered heterointerfaces that facilitate multi-path energy dissipation via magneto–dielectric coupling optimized impedance matching, intensive interfacial polarization from abundant hierarchical architectures and the flower-like structure induced multiple scatterings. This study highlights the pivotal role of interfacial engineering in heterostructured absorbers and offers a design paradigm for high-performance EMW-absorbing materials through coordinated component–structure modulation.

In this work, a novel ternary heterojunction consisting
of Zn vacancy-rich
zinc oxide (Zn 1– x O), a zeolitic
imidazolate framework-8 (ZIF-8), and cobalt phthalocyanine (CoPc)
was fabricated for photocatalytic N 2 fixation. The Zn 1– x O/ZIF-8 composite with bridged O–Zn–N
bonding was synthesized via in situ growth of ZIF-8 on Zn 1– x O, and it possessed a large surface area favorable
for N 2 adsorption. The incorporation of CoPc with dispersed
Co–N 4 (II) sites enhanced light harvesting and N 2 activation. Zn vacancies and coupled type II/Z-scheme charge
transfer pathways in the heterojunction accelerated the separation
of photogenerated charge carriers. As a result, the optimized catalyst
exhibited superior and stable photocatalytic N 2 reduction
performance via an alternating pathway in water, with an NH 4 + production rate of 65.2 μmol g –1 h –1 , which is 17.0 times higher than that of ZnO.
This study develops a novel ZnO-based heterojunction that simultaneously
optimizes multiple key factors for efficient photocatalytic N 2 fixation.

To reduce the oxidation damage during the initial active oxidation stage of ZrB 2 -SiC coating, this paper employed a slurry-brushing method to prepare a self-healing Zr-Si-B-O biomimetic glass film on the surface of the ZrB 2 -SiC coating. Furthermore, the oxidation resistance behavior of biomimetic glass films with varying ZrO 2 contents was investigated. Experimental results indicate that the Zr-Si-B-O biomimetic glass film can significantly reduce the oxidation weight gain of ZrB 2 -SiC coating. The biomimetic glass film sample with 70 wt% ZrO 2 exhibits the best oxidation protection effect. After oxidation treatment in the temperature range of 600-1600 °C, the weight gain is only 0.081 × 10 −2 g cm −2 , which is 95.35% lower than that of the sample without the biomimetic glass film; after oxidation at 1700 °C, the final protection efficiency and average carbon loss rate reach the optimal values of 99.97% and 0.34 × 10 −6 g cm −2 s −1 , respectively, and the average oxygen permeability is only 0.35%. The presence of Zr-Si-B-O biomimetic glass film can significantly reduce the oxidation activity and improve the oxidation resistance of the coating. This is attributed to the pre-introduction of a flowable and self-healing glass on the coating surface, which prevented the intense oxidation of the coating at the initial stage.

The development of electrocatalysts that simultaneously exhibit high activity and robust stability for the oxygen evolution reaction (OER) is critical to advancing proton exchange membrane water electrolysis (PEMWE). In this work, Mn-doped RuO2 is composited with acid-resistant and highly conductive Ti4O7 via a simple molten salt method, yielding a Mn-RuO2/Ti4O7 hybrid electrocatalyst. Electrochemical measurements reveal that Mn-RuO2/Ti4O7 achieves a low overpotential of 194 mV at 10 mA cm⁻² and maintains stable operation for over 220 h at this current density. In situ spectroscopic analysis and computational studies further indicate that Mn doping modulates the electronic interplay between RuO2 and Ti4O7, which not only suppresses over-oxidation of Ru at high potentials but also promotes the deprotonation kinetics of reaction intermediates, thereby significantly enhancing the overall catalytic performance. This work offers an effective strategy for balancing activity and stability in acidic OER electrocatalys.

Catalytic ozone decomposition offers a promising approach for controlling ground-level ozone (O 3 ), but conventional Co-based catalysts suffer from poor performance due to nanoparticle agglomeration and limited electronic tunability. This study addresses these limitations by leveraging electronic metal-support interaction (EMSI) to engineer a Co-based catalyst (Cox@SBA-UC) anchored via Si–O–Co bonding on a mesoporous SBA-UC carrier. We demonstrate that the Si–O–Co EMSI structure enhances Co dispersion, stabilizes low-valence Co 2+ species, and optimizes electronic properties by upshifting the d -band center. The optimized Co2@SBA-UC catalyst achieves exceptional O 3 decomposition efficiency (92% conversion), outperforming control catalysts and exhibiting robust humidity resistance. Mechanistic insights reveal strengthened O 3 adsorption and facilitated decomposition into surface oxygen intermediates (*O and *O 2 ), while reversible deactivation caused by *O 2 accumulation is efficiently mitigated through thermal regeneration under an inert atmosphere. This work provides a sustainable strategy for catalytic ozone decomposition by simultaneously maximizing active site density and intrinsic activity, advancing environmental remediation technologies for clean air applications.
