The utilization of self-healing polymers is a promising way of solving problems associated with the wear and tear of polymer products, such as those caused by mechanical stress or environmental factors. In this study, a series of novel self-healing, high-strength copolymers of acrylamide, acrylic acid, and novel acrylic complexes of 4′-phenyl-2,2′:6′,2″-terpyridine [Co(II), Ni(II), and Cu(II)] was prepared. A systematic study of the composition and properties of the obtained polymers was carried out using a variety of physicochemical techniques (elemental analysis, gel permeation chromatography (GPC), attenuated total reflectance Fourier transform infrared spectroscopy (ATR/FT-IR), ultraviolet-visible spectroscopy (UV-vis), small-angle X-ray scattering (SAXS), wide-angle X-ray scattering (WAXS), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA), confocal laser scanning microscopy (CLSM), and tensile testing). All metallopolymer samples exhibit autonomous intrinsic healing along with maintaining high tensile strength values (for some samples, the initial tensile strength exceeded 100 MPa). The best values of healing efficiency are possessed by metallopolymers with a nickel complex (up to 83%), which is most likely due to the highest lability of the metal–heteroatom coordination bonds. The example of this system shows the ability to re-heal with negligible deterioration of the mechanical properties. The possibility of tuning the mechanical properties of self-healing films through the use of different metal ions has been demonstrated.

In this paper composites containing metal-organic framework MIL88b(Fe), nanoparticles magnetite (Fe3O4) or maghemite (γ-Fe2O3) modified by humic acids or ascorbic acid were synthesized and tested in the decomposition reaction of methylene blue. Analysis of predictive model based on multi-factor correlation analysis «physical-chemical properties — concentration of methylene blue after degradation» showed that in a line of selected parameters (initial iron concentration in sample, elemental cell parameter, Fe2+/Fe3+ ion ratio on sample surface, total iron ion released concentration, surface area specific, surface charge), a significant factor influencing Fenton reaction kinetics, is only the total concentration of the released iron ions (p-value = 0.0162). The influence of separate Fe2+ and Fe3+ ions and reaction time on the Fenton reaction kinetics was evaluated by multi-factor analysis. The results demonstrated that concentrations of released iron ions are statistically significant, with a square of the concentration of ions Fe2+ and the result of the reaction time to the concentration of ions Fe3+. A comparison of the sign and the coefficient values shows that an increase in ion concentration results in a reduction in methylene blue concentration, thereby accelerating the Fenton reaction rate, with Fe2+ ion concentration affecting more than Fe3+. The resulting model is proposed as a means of selecting a sample with the maximum Fenton reaction rate at a given point in time.

Hydrogenation is a widely used reaction in the oil processing and industrial organic synthesis. UiO-66 is a prom-ising porous organic-inorganic material that can be used as a support for catalytically active particles. The key part in the application of highly porous UiO-66 is the search of a simple synthesis method that meets international environmental standards. In this study, a "rational" method for the synthesis of MOFs was used to produce UiO-66. The use of pre-synthesized multinuclear zirconia clusters facilitates the synthesis of the desired network to-pology, enabling the process to be conducted in an environmentally friendly aqueous solution. The effects of re-action temperature, linker volume concentration and solvent type on the specific surface area and thermal properties were also evaluated in this work. We studied the composition, structure and physicochemical properties of the obtained compounds by IR spectroscopy, TGA and XRD analysis. The proposed procedure has been shown to yield UiO-66 with high specific surface area (SBET = 885 m2/g) and to extend the thermal stability range up to 490 °C. The post-synthetic modification of the obtained UiO-66 with the introduction of catalytically active Pd (Pd/UiO-66) was carried out, and high selectivity (83,0 %) of the obtained Pd/UiO-66 exhibited high selectivity in the hydrogenation reaction of p-chloronitrobenzene into p-chloroaniline in comparison with the traditional Pd/Al2O3.

Industry-wide applications of synthetic dyes produce large amounts of dye wastewater that requires treatment. Advanced oxidation processes are considered promising, since they incorporate highly reactive hydroxyl radicals capable of oxidizing most organic pollutants, including most commonly used azo dyes, into carbon dioxide and water. In this regard, iron-based metal-organic frameworks are effective heterogeneous photocatalysts for the generation hydroxyl radicals via Fenton reaction. In this study, Fe3O4/Fe2O3@MIL-88b(Fe) and Fe3O4/γ-Fe2O3@NH2-MIL-88b(Fe) composites were obtained, where Fe3O4/γ-Fe2O3 particles enabled magnetic separation, and Fe-metal-organic frameworks (MOF) coating exhibited photocatalytic activity. These composites were characterized by elemental analysis, FTIR spectra, XRD patterns, magnetization curves, TGA profiles, nitrogen adsorption-desorption isotherms. Using ultraviolet-visible spectroscopy and Congo Red anionic azo dye (CR) as organic pollutant, composites’ adsorption kinetics were observed and their photocatalytic activities were studied. As a result, Fe3O4/γ-Fe2O3@MIL-88b(Fe) and Fe3O4/γ-Fe2O3@NH2-MIL-88b(Fe) were both capable photocatalysts for generating hydroxyl radicals from hydrogen peroxide (H2O2) through Fenton-like reaction with removal efficiencies of CR dye approaching 89 % and 95 %, respectively. Moreover, a higher photocatalytic activity was observed for Fe3O4/γ-Fe2O3@NH2-MIL-88b(Fe), supposedly, due to -NH2 group increasing the electron density on the aryl ring, which stabilized hole localization at the organic linker, increased photoexcited state lifetime and promoted electron transfer onto metal center in Fe3-μ3-O cluster

The results of a Fourier-transform IR spectroscopic study of polypropylene (PP) subjected to gamma-irradiation and post-irradiation high-temperature shear grinding are presented. The IR spectra of PP granules irradiated in air exhibited absorption peaks of hydroxyl and oxygen-containing groups, the intensity of which noticeably decreased in the powder obtained by grinding the irradiated polymer granules. The toxic properties of PP obtained by high-temperature shear grinding of irradiated polymer granules were investigated. It was found that gamma-irradiation of polymer granules in air did not affect the toxic properties of polymer powder obtained by grinding granules irradiated with a dose of 700−4500 kGy. It was established that PP powder obtained from unirradiated and irradiated granules was a moderately toxic substance when administered intragastrically to BDF1 mice.

Abstract Iron-containing metal–organic frameworks are promising Fenton catalysts. However, the absence of additional modifiers has proven difficult due to the low reaction rates and the inability to manipulate the catalysts. We hypothesize that the production of iron oxide NPs in the presence of a metal-organic framework will increase the rate of the Fenton reaction and lead to the production of particles that can be magnetically manipulated without changing the structure of the components. A comprehensive approach lead to a metal organic framework using the example of MIL-88b (Materials of Institute Lavoisier) modified with iron oxides NPs: formulation of iron oxide in the presence of MIL-88b and vice versa. The synthesis of MIL-88b consists of preparing a complexation compound with the respective structure and addition of terephthalic acid. The synthesis of MIL-88b facilitates to control the topology of the resulting material. Both methods for composite formulation lead to the preservation of the structure of iron oxide, however, a more technologically complex approach to obtaining MIL-88b in the presence of Fe3O4 suddenly turned out to be the more efficient for the release of iron ions.

Because of their special qualities, metal-organic frameworks, or MOFs, have drawn a lot of interest for their potential in chemiresistive ethanol sensing. Three distinct MOF materials Zr6O4(OH)4(TPA-NH2)6, Zr6O4(OH)4TPA6, and Zr6O4(OH)4NDCA6 were thoroughly examined and fabricated in this work to determine which was most appropriate for use in ethanol sensing applications. According to Tauc plot analysis, Zr6O4(OH)4(TPA-NH2)6 had the lowest optical band gap energy, 3.79 eV. FTIR spectroscopy further showed the various vibrational modes in each MOF, with Zr6O4(OH)4(TPA-NH2)6, exhibiting peculiar absorption peaks at 488 and 767 cm− 1. Dynamic light scattering provided information on Zr6O4(OH)4(TPA-NH2)6 particle size distribution. Moreover, Zr6O4(OH)4(TPA-NH2)6 demonstrated remarkable sensitivity in chemiresistive ethanol sensing, as it continuously had the strongest sensor response at various ethanol concentrations. Zr6O4(OH)4(TPA-NH2)6 was found to have the lowest limit of detection (8.69 ppm) in LOD study, indicating that it is very sensitive to ethanol. Zr6O4(OH)4(TPA-NH2)6 was shown to be the most selective for ethanol based on selectivity testing. Zr6O4(OH)4(TPA-NH2)6 exhibited the fastest response time and most effective recovery, as seen by their response and recovery times. These results offer important new understandings of the properties and functionality of MOFs for chemiresistive ethanol sensing, with Zr6O4(OH)4(TPA-NH2)6 showing great promise.

Stabilization of the properties of epoxy materials in response to ionizing radiation is an important task for predicting the service life of the product. This study investigated the effect of γ-radiation on the structure and mechanical and thermal stability of epoxy nanocomposites with TiO2 nanoparticles (n-TiO2). The oxidation of epoxy chain bonds at doses above 42 kGy was shown using IR spectroscopy. The addition of n-TiO2 makes it possible to increase the strength and strain and also stabilize the mechanical and thermal properties of the composite with respect to γ-radiation.

Bimetallic FeCo and FeNi nanoparticles attract much attention due to their promising magnetic properties and a wide range of practical applications as recording and storage media, catalytic systems in fuel cells, supercapacitors, lithium batteries, etc. In this paper, we propose an original approach to the preparation of FeCo- and FeNi/N-doped carbon nanocomposites by means of a coupled process of frontal polymerization and thermolysis of molecular co-crystallized acrylamide complexes. The phase composition, structure, and microstructure of the resulting nanocomposites are studied using XRD, IR spectroscopy, elemental and thermal analysis, and electron microscopy data. The main magnetic characteristics of the synthesized nanocomposites, including the field dependences and the ZFC-FC curves peculiarities, are studied. It is shown that the obtained FeCo/N-C nanocomposites exhibit exchange bias behavior at low temperatures. In turn, FeNi/N-C nanocomposites are ferromagnetically ordered.

In recent years, the synthesis of new gas-sensitive materials for resistive humidity sensors has attracted significant interest. In the present paper, nickel-containing metal-polymer nanocomposites were obtained by thermolysis of nickel itaconate (I) and its complexes with 2,2′-dipyridyl (II), 1,10-phenanthroline (III) and 4′-phenyl-2,2′:6′,2''-terpyridine (IV). The formed nanocomposites were characterized by FTIR, elemental analysis, EDX, SEM, TEM and XRD studies. The most common particle sizes are 28, 12.8, 10.7 and 12.3 nm for the thermolysis products of compounds I–IV respectively. The manufactured sensor samples have good sensitivity to air relative humidity (RH) of 3.24 %/%RH, 4.72 %/%RH, 2.18 %/%RH and 4.37 %/%RH for thermolysis products of compounds I–IV with the polymer binder polyacrylamide, respectively. The average initial resistance of the sensors is 4.54, 15.33, 20.8 and 35.75 MΩ, respectively. Due to the high porosity and moisture absorption of the film, the maximum sensitivity was about 0.003 MΩ/%RH, which indicates a fairly effective behavior of the film with respect to humidity. The response times were 27, 25, 33, 30 s, and the recovery time 47, 44, 51, 49 s, respectively, and repeating the experiment resulted in 87–92 % reproducible results. The fabricated sensors have great potential for use as a humidity sensing element in sensors that can be used for humidity monitoring.

The designed nanocomposite film of self-assembled 2D Ag-doped CuO:SnO2 nanoflakes have been successfully synthesized through facile one-step hydrothermal technique. The fabricated sensor film is developed to detect liquefied petroleum gas (LPG) at room temperature. X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and UV-visible spectroscopy comprehensively characterize the film's microstructure, morphology, element composition, and optical properties. The LPG sensing outcomes reveal that the Ag-doped CuO:SnO2 film based sensor exhibits exceptional response and excellent repeatability towards LPG at room temperature. This is predominantly due to formation of CuO: SnO2 interface, sensitized by doping silver (Ag) that drastically increases the carrier concentration of the NC sensor film and provides superior ability to detect LPG across a range of concentrations at room temperature. The sensor response increases from 300% for 0.5 vol.% LPG to a maximum of 414% at 2.0 vol.%. Notably, the sensor demonstrates fast response and recovery times (21 s and 30 s for 0.5 vol.% LPG). These promising attributes position the NC sensor film as a strong candidate for real-world LPG sensing applications. Additionally, the research proposes a comprehensive mechanism explaining the NC sensor film's detection performance.

The applicability of the conventional Fenton reaction is limited due to several factors, including the high cost and slow redox cycle of Fe3+/Fe2+, the requirement for harsh acidic conditions, and the insufficient presence of hydroxyl radicals for the ring-opening reaction. The combination of photocatalysis and Fenton technology to create a photocatalysis-in-situ-self-Fenton (PISF) system is a viable approach for addressing the inherent limitations of conventional Fenton reactions. Herein, a multifunctional PISF system, MIL-88A(Fe)/Ti3C2 MXene/resorcinol-formaldehyde (MIL-88A(Fe)/Ti3C2/RF, MTR) Z-scheme heterojunction, was designed and constructed for degradating organics and inactivating bacteria. With the assistance of Ti3C2, the degradation rate of TC by MTR catalyst was 4.8 times that of MIL-88A(Fe)/RF catalyst under visible light irradiation. Meanwhile, good degradation performance was maintained after 5 cycling tests. The remarkable TC removal efficiency (97.4%) and durability were attributed to the synergistic effect of the photocatalytic reaction and Fenton reaction. The photoinduced holes (h+) assist hydroxyl radicals (•OH) generated by the Fenton reaction for deeply mineralizing TC. The degradation intermediates, potential degradation pathways, and intermediates toxicity were comprehensively investigated to gain a deeper understanding of the catalytic process. Moreover, under visible light irradiation, the MTR killed 97.8% of E. coli and 94.9% of S. aureus within 120 min, demonstrating good antibacterial activity. This work provides a novel strategy to design PISF catalysts for environmental remediation.

AbstractAn acidic gas is an important basic chemical raw material used for synthesizing fertilizers, insecticides, explosives, dyes, and salts. Alternatively, inorganic acidic gases that leak into the air have harmful effects on the human health, infrastructure, and cultural relics. Therefore, the demand for inorganic acidic gas sensors for air quality monitoring and management has continuously increased, enabling the development of various sensing technologies. Among them, fiber-optic sensors are promising for acidic gas detection because of their excellent in-situ measurement, resistance to corrosion, anti-electromagnetic interference, long service life, and smart structure. In particular, fiber-optic sensors have proven to be very useful for the in-situ detection and distributed monitoring of multiple gas parameters. However, the sensitivity, selectivity, repeatability, and limits of detection of these sensors can be improved to achieve acceptable performance levels for practical applications. In this review, we introduce fiber-optic sensors based on structured optical fibers and fiber gratings for detecting H2S, SO2, NO2, CO2, and N2O. The structures of the sensing regions, gas-sensitive materials, and measurement principles of these sensors are presented. The sensitivity, selectivity, limit of detection, and response time of the sensors are summarized. Finally, the future of fiber-optic sensors for the detection of inorganic acidic gases is discussed.

Efficient generation and rapid activation of H2O2 are essential for a self-sufficient photo-Fenton-like system. Herein, ferric-ellagate complex (EA-Fe), the atomically distributed Fe active catalyst, was first employed to activate the H2O2 photo-generated by resorcinol–formaldehyde (RF) resins. During the photo-Fenton-like reactions, the photoinduced holes (h+), hydroxyl radicals (•OH) and superoxide radicals (•O2–) work together for organics degradation and bacteria inactivation. The degradation intermediates were identified by HPLC-EIS-MS and the possible degradation pathways of TC were proposed. Meanwhile, the QSAR prediction revealed that the catalytic processes could significantly eliminate ecotoxicity. Moreover, the RF/EA-Fe could effectively inactivate both E. coli and S. aureus. Theoretical calculations indicated that the H2O2 molecule was adsorbed on the Fe atom through a single Fe-O coordination, followed by conversion to *OH (Fe-OH) via directly breaking the peroxy bond. This activation pathway effectively maximizes the utilization of H2O2. This study can provide a new platform for rationally designing a self-cycled photo-Fenton-like system with outstanding degradation and antibacterial properties.

In recent years, the emerging two−dimensional material−MXenes has attracted widespread attention in the field of photocatalysis due to its high conductivity, suitable Fermi level, tunable elemental composition, and excellent photoelectric properties. The zero−dimensional quantum dots (MQDs) derived from 2D MXenes not only inherit the characteristics of MXenes but also exhibit better performance due to the quantum size effect. Based on the above excellent physical and chemical properties, MQDs are often used as co−catalysts of photocatalysts, and show excellent co−catalytic properties. At the same time, compared with other cocatalysts (precious metals, metal oxides, metal sulfides), it has the advantages of low cost and high conductivity. Therefore, understanding the status of MQDs in the field of photocatalysis is crucial for their further development. In this review, we summarized the synthesis and modification methods of MQDs in recent years, as well as their photocatalytic applications in H2 production, CO2 reduction, N2 fixation, pollutant degradation, and other aspects. In addition, the challenges and prospects faced by MQDs are also proposed, providing theoretical guidance for the further development of MQD−based photocatalysts.

A series of stimuli-responsive fluorescent hydrogels were successfully synthesized via micelle radical copolymerization of hydrophilic acrylamide (AM), hydrophobic chromophore terpyridine-based monomer (TPY), and N-isopropylacrylamide (NIPAM). These hydrogels presented blue emissions (423–440 nm) under room temperature, which is caused by the π-π* transition of the conjugated structures. Once the ambient temperature was increased to 55 °C, the fluorescence color changed from blue (430 nm) to pink (575 nm) within 10 min, subsequently to yellow (535 nm), and eventually back to pink. The thermal-responsive properties are attributed to the transition of the TPY units from unimer to dimer aggregation via the intermolecular charge transfer complex at high temperatures. The hydrogels showed pH-responsive properties. The emission peak of the hydrogel exhibited a blue shift of ~54 nm from neuter conditions to acidic conditions, while a 6 nm red shift to an alkaline environment was observed. The hydrogels demonstrated an obvious change in fluorescence intensity and wavelength upon adding different metal ions, which is caused by the coordination between the terpyridine units incorporated on the backbones and the metal ions. As a consequence, the hydrogels presented a sharp quenching fluorescence interaction with Fe2+, Fe3+, Cu2+, Hg2+, Ni2+, and Co2+, while it exhibited an enhanced fluorescence intensity interaction with Sn2+, Cd2+, and Zn2+. The microstructural, mechanical, and rheological properties of these luminescent hydrogels have been systematically investigated.

Ultraviolet (UV) irradiation significantly contributes to photoaging. Ferroptosis, an iron-dependent cell death mode recently identified, plays a key role in UVB-induced skin photoaging. This study examines the functions and regulatory mechanisms of ferroptosis in this regard. Characterized by increased intracellular iron and reactive oxygen species (ROS), ferroptosis is associated with mitochondrial function and structure. Through RNA sequencing, we identified NADH: ubiquinone oxidoreductase subunit S4 (NDUFS4), a gene implicated in UVB-mediated photoaging, and explored its role in ferroptosis by NDUFS4 knockdown. In vitro, inhibiting NDUFS4 reduced ferroptosis, decreased ROS and matrix metallopeptidase 1 levels, and increased collagen type I alpha 1 chain, glutathione peroxidase 4 (GPX4), ferritin heavy chain 1, and solute carrier family 7 member 11 levels, suggesting a reinforced ferroptosis protective mechanism. Additionally, NDUFS4 regulates ferroptosis via the mitogen-activated protein kinase (MAPK) pathway, with its knockdown reducing p38 and ERK phosphorylation and elevating GPX4 levels, enhancing ferroptosis resistance. Animal experiments supported these findings, demonstrating that Ferrostatin-1, a ferroptosis inhibitor, significantly mitigated UVB-induced skin photoaging and related protein expression. This study uncovers NDUFS4's novel role in regulating ferroptosis and provides new insights into ferroptosis-mediated UVB-induced skin photoaging.

The establishment of heterojunctions was considered as an exceptional strategy to obtain high-efficiency charge separation and enhanced photocatalytic performance. Herein, a series of FePMo/MIL-53(Fe) (FeM-53) heterojunctions were successfully constructed through in-situ growth of FePMo onto MIL-53(Fe) surface and their photocatalytic capacity were examined by visible-light-induced Cr(VI) reduction. Interestingly, the as-fabricated composites offered various photocatalytic activities controllably relying on the mass ratio of FePMo to MIL-53(Fe). Particularly, the one with the 10% ratio displayed the highest Cr(VI) reduction rate (100%) within 75 min, which was respectively over 4 and 2 folds higher than pure FePMo and MIL-53(Fe). The boosted photoactivity might be ascribed to the establishment of S-scheme heterojunction with suitable band alignment between FePMo and MIL-53(Fe), which broadened the light absorption range and improved charge separation. Further mechanism investigations implied both •O2- and e- were the key reactive species for Cr(VI) removal. Besides, the composite preserved excellent stability after 4 consecutive tests, and performed well in the presence of organic dyes. Such a S-scheme heterojunction may promise for highly efficient environmental mitigation.

Abstract Iron-containing metal–organic frameworks are promising Fenton catalysts. However, the absence of additional modifiers has proven difficult due to the low reaction rates and the inability to manipulate the catalysts. We hypothesize that the production of iron oxide NPs in the presence of a metal-organic framework will increase the rate of the Fenton reaction and lead to the production of particles that can be magnetically manipulated without changing the structure of the components. A comprehensive approach lead to a metal organic framework using the example of MIL-88b (Materials of Institute Lavoisier) modified with iron oxides NPs: formulation of iron oxide in the presence of MIL-88b and vice versa. The synthesis of MIL-88b consists of preparing a complexation compound with the respective structure and addition of terephthalic acid. The synthesis of MIL-88b facilitates to control the topology of the resulting material. Both methods for composite formulation lead to the preservation of the structure of iron oxide, however, a more technologically complex approach to obtaining MIL-88b in the presence of Fe3O4 suddenly turned out to be the more efficient for the release of iron ions.
