Liu, Yang;Guo, Hongguang;Zhang, Yongli;Cheng, Xin;Zhou, Peng;Wang, Jingquan;Li, Wei research published 《 Fe@C carbonized resin for peroxymonosulfate activation and bisphenol S degradation》, the research content is summarized as follows. Aiming at realizing heavy metal recycling and resource utilization, a carbon-based iron catalyst (Fe@C) was synthesized through a resin carbonization method, and adopted for peroxymonosulfate (PMS) activation to remove bisphenol S (BPS), an emerging aquatic contaminant. This study demonstrated that Fe@C exhibited excellent catalytic potential for BPS degradation with a relatively low activation energy (E_a = 29.90 kJ/mol). Kinetic factors affecting the activation performance were thoroughly investigated. The obtained results indicated that Fe@C composite exhibited the superior uniformity with carbon as the framework and granular iron oxide as the coverage. pH increase could cause the inhibitive effect on BPS degradation, while the increasing catalyst loading (0.05-0.5 g/L) was conducive for the catalytic performance of Fe@C, with an optimal PMS concentration at 1.0 mM. A neg. influence on BPS degradation was obtained in the presence of SO^2-₄, HCO^–₃ and lower concentration of Cl^– (0-20 mM), compared to the promotion at higher concentration of Cl^– (>50 mM). Based on the ESR (ESR) monitoring and radical scavenging results, it is demonstrated that singlet oxygen, a non-radical species, emerged together with ·SO^–₄ and ·OH for BPS degradation A three-channel catalytic mechanism was verified through typical characterizations. Furthermore, the degradation pathway of BPS was proposed based on the identified intermediates. This novel carbon-based activator for PMS showed notable potential for the waste resin recycling and water decontamination. A novel Fe-based activator carbonized from a saturated resin exhibits excellent performance for Bisphenol S degradation with activated peroxymonosulfate.

Khan, Ajmir;Rabnawaz, Muhammad research published 《 Base-Layer-Driven Self-Healing Materials》, the research content is summarized as follows. Despite the enormous potential applications for intrinsic self-healing materials, these materials have reached a road-block where concurrent excellent mech. properties and autonomous self-healing behavior are impossible. Herein reported is a base-layer-driven self-healing (BLDS) approach that facilitates self-healing irresp. of the glass transition (T_g) or melting temperature (T_m) of the top layer. The BLDS approach enables autonomous self-healing materials that concurrently offer ultramech. durability and ambient healing. The BLDS relies on an ambient healable base layer and a structural/functional top layer. In this study, the bottom layer is prepared using reversible-dynamic covalent linkages in polyurethane/urea. Meanwhile, the top layer is selected from a thermoplastic (e.g., polylactic acid), thermoset (e.g., polyurethane), and functional thermosets (e.g., omniphobic urethane). The resultant dual-layer coatings/films offer a modulus of >800 MPa and still maintained excellent ambient self-healing. The antirust efficacy of the BLDS coating is also demonstrated. As the top layer can be selected from any com. structural and functional materials, this work opens a whole different direction for autonomous healable materials, which will open addnl. avenues of real-world applications.

The mol. orientation and dynamics were examined for 4-acetamido-2,2,6,6-tetramethyl-1-piperidinyloxyl (4-acetamido-TEMPO) radicals, which have a larger substituent group than many other TEMPO radicals, dispersed in the one-dimensional (1D) nanochannel of 2,4,6-tris(4-chlorophenoxy)-1,3,5-triazine (CLPOT) with 4-substituted-2,2,6,6-tetramethylpiperidine (R-TEMP; R=OH or H). When TEMPOH (R=OH) was used as a spacer for dispersion in the CLPOT nanochannels, the mol. orientation of 4-acetamido-TEMPO in the CLPOT nanochannels was similar to that of other previously reported 4-substituted-TEMPO (4-X-TEMPO; X=OH, =O or OCH₃) radicals. However, the activation energy for the rotational diffusion of 4-acetamido-TEMPO in the CLPOT nanochannels, estimated to be 11 kJ mol^-1, was larger than that of other 4-X-TEMPO mols. (6-8 kJ mol^-1). These results indicate that the mol. dynamics of 4-X-TEMPO in the CLPOT nanochannels can be controlled by the selection of a larger substituent X at the 4-position in 4-X-TEMPO (in this study, X=NHCOCH₃), and also suggest an important concept for the design of new organic magnets.

Kolkman, Annemieke;Vughs, Dennis;Sjerps, Rosa;Kooij, Pascal J. F.;van der Kooi, Margo;Baken, Kirsten;Louisse, Jochem;de Voogt, Pim research published 《 Assessment of Highly Polar Chemicals in Dutch and Flemish Drinking Water and Its Sources: Presence and Potential Risks》, the research content is summarized as follows. Highly polar chems. are mobile in an aqueous environment. Anal. methods for these compounds in water are lacking. A combined target/nontarget screening method based on hydrophilic interaction LC coupled to high-resolution MS was developed. Thirty-two highly polar chems. (including melem and melam) can thus be quant. measured in surface water and drinking water, and the MS data can be screened for unknown compounds This is the first time a method for the determination of melem and melam in water has been described. The method is complementary to existing target and nontarget methods for less polar substances and can be applied for (drinking) water quality assessment. In a screening study in The Netherlands and Flanders, 12 of the 32 compounds were encountered in groundwater, surface water, and drinking water at levels between 0.01 and 4.2μg/L. Concentrations in drinking water were compared with (provisional) guideline values to assess whether these may pose a concern for human health. In one drinking water sample, the concentration of dichloroacetic acid exceeded the provisional guideline value, indicating that health effects cannot be excluded on the basis of lifetime exposure. For most chems., reliable drinking water guideline values could not be derived due to the limited available of toxicity data. The assessment of drinking water quality based on a new anal. method is presented along with derivation of guideline values for highly polar chems.

Krasowska, Joanna;Pierzchala, Katarzyna;Bzowska, Agnieszka;Forro, Laszlo;Sienkiewicz, Andrzej;Wielgus-Kutrowska, Beata research published 《 Chromophore of an Enhanced Green Fluorescent Protein Can Play a Photoprotective Role Due to Photobleaching》, the research content is summarized as follows. Under stress conditions, elevated levels of cellular reactive oxygen species (ROS) may impair crucial cellular structures. To counteract the resulting oxidative damage, living cells are equipped with several defense mechanisms, including photoprotective functions of specific proteins. Here, we discuss the plausible ROS scavenging mechanisms by the enhanced green fluorescent protein, EGFP. To check if this protein could fulfill a photoprotective function, we employed ESR (ESR) in combination with spin-trapping. Two organic photosensitizers, rose bengal and methylene blue, as well as an inorganic photocatalyst, nano-TiO₂, were used to photogenerate ROS.67. Spin-traps, TMP-OH and DMPO, and a nitroxide radical, TEMPOL, served as mol. targets for ROS. Our results show that EGFP quenches various forms of ROS, including superoxide radicals and singlet oxygen. Compared to the three proteins PNP, papain, and BSA, EGFP revealed high ROS quenching ability, which suggests its photoprotective role in living systems. Damage to the EGFP chromophore was also observed under strong photo-oxidative conditions. This study contributes to the discussion on the protective function of fluorescent proteins homologous to the green fluorescent protein (GFP). It also draws attention to the possible interactions of GFP-like proteins with ROS in systems where such proteins are used as biol. markers.

Lang, Yunhe;Wu, Shihong;Yang, Qin;Luo, Yanju;Jiang, Xia;Wu, Peng research published 《 Analysis of the Isotopic Purity of D₂O with the Characteristic NIR-II Phosphorescence of Singlet Oxygen from a Photostable Polythiophene Photosensitizer》, the research content is summarized as follows. D₂O plays important roles in a variety of fields (such as the nuclear industry and bioorganic anal.), and thus its isotopic purity (H₂O contents) is highly concerned. Due to its highly similar phys. properties to H₂O and large excess amounts of H₂O over D₂O, it is challenging to distinguish D₂O from H₂O. On the basis of the characteristic NIR-II phosphorescence of singlet oxygen (¹O₂), and the fact that H₂O is a more efficient quencher for ¹O₂ than D₂O, here, we proposed to simply use the 1275 nm emission of ¹O₂ for the anal. of the isotopic purity of D₂O. In normal cases (a xenon lamp for excitation), such steady-state emission is extremely weak for valid anal. applications, we thus employed laser excitation for intensification. To this goal, a series of photosensitizers were screened, and eventually polythiophene PT10 was selected with high singlet oxygen quantum yield (Φ_Δ = 0.51), high H₂O/D₂O contrast, and excellent photostability. Upon excitation with a 445 nm laser, a limit of detection (LOD, 3σ) of 0.1% for H₂O in D₂O was achieved. The accuracy of the proposed method was verified by the anal. of the isotopic purity of several D₂O samples (with randomly added H₂O). More interestingly, the hygroscopicity of D₂O was sensitively monitored with the proposed probe in a real-time manner; the results of which are important for strengthening the care of D₂O storage and the importance of humidity control during related investigations. Besides D₂O isotopic purity evaluation, this work also indicated the potential usefulness of the NIR-II emission of singlet oxygen in future anal. detection.

Lau, Mei-Tung;Li, Zikang;Sun, Zelin;Wong, Wai-Yeung research published 《 Synthesis, characterization and thermoelectric properties of new non-conjugated nitroxide radical-containing metallopolymers》, the research content is summarized as follows. In the last decade, there is an intense interest in the study of conjugated organic polymers for thermoelec. (TE) application. Non-conjugated polymers are usually considered as the insulators with no or extremely low elec. conductivity Nevertheless, non-conjugated radical polymers (NCRPs) are different from those polymers in which they can be widely applied in electronic technol., for example, as battery electrode materials, conductors in solid-state and memory devices, but they have not been used for the TE application. Here, three metal-containing NCRPs P1-P3 with different nitroxide radical moieties were synthesized and coated with single-walled carbon nanotubes (SWCNTs) to form various polymer composites. P2 exhibited the highest elec. conductivity of 1310.0 ± 3.92 S m^-1 when the SWCNT content reached 60%. P3 had the highest Seebeck coefficient of 62.5 ± 0.40μV K^-1 when the SWCNT ratio reached 90%. The highest power factor of 130.1 ± 1.61μW m^-1 K^-2 was achieved from the P3/SWCNT composite at the mass ratio of 90%. The results showed that the NCRPs could be one of the potential TE materials of further study.

Environmental friendly magnetic Fe₃O₄/β-FeOOH nanocomposites with low cost were prepared via a simple one pot method and their physiochem. properties were investigated. The Fe₃O₄/β-FeOOH nanocomposites efficiently catalyzed the activation of peroxymonosulfate (PMS) for sulfamethoxazole (SMX) degradation and can be easily recovered through magnetic separation The effects of catalyst dosage, PMS dosage, temperature and pH were evaluated. The catalyst showed great stability and reusability based on the successive degradation cycles. The reactive oxygen species (ROS) including sulfate radical (SO^-·₄), hydroxyl radical (·OH) and singlet oxygen (¹O₂) were generated in the Fe₃O₄/β-FeOOH/PMS system, while both of SO^-·₄ and ¹O₂ were dominantly attributed to the SMX degradation The special tunnel-type structure and surface oxygen vacancies of β-FeOOH may be responsible for the high catalytic activity towards PMS to degrade SMX. At last, the catalytic mechanism of PMS on the surface of catalysts were proposed.

The formation of halogenated disinfection byproducts (DBPs) during organic pollutants degradation in advanced oxidation processes (AOPs) has raised growing concerns globally. However, the detailed roles of chlorine ions (Cl^–) in pollutant degradation by peroxymonosulfate (PMS) alone remain controversial so far. Here, we shed light on the PMS-Cl^–-phenol interactions and revealed a previously overlooked pH-dependent phenol transformation pathway. At acidic pH, Cl^– significantly accelerated the phenol removal. The Cl^–-PMS reaction resulted in abundant reactive chlorine species, which attacked phenol to form 4-chlorophenol and 2, 4-dichlorophenol as the main transformation products. In contrast, the impact of Cl^– became negligible at alk. pH. Raising the pH severely suppressed the phenol chlorination and significantly stimulated generation of singlet oxygen (¹O₂) for degradation of phenol and the minor formed chlorophenols. The ¹O₂ was resulted from a combined effect of PMS self-decomposition and PMS-benzoquinone interaction at alk. pH. Our results imply a previously-underestimated impact of Cl^– on phenolic compounds degradation in PMS-based AOPs and underscore a potential risk of chlorinated DBPs formation under environmental conditions.

Li, Hongdan;Wang, Jiawei;Du, Jianxiu research published 《 A novel luminol chemiluminescence system induced by black phosphorus quantum dots for cobalt (II) detection》, the research content is summarized as follows. Black phosphorus quantum dots (BP QDs) were prepared through a solvothermal exfoliation method in alk. N-methyl-2-pyrrolidinone. The BP QDs induce distinct chemiluminescence (CL) of alk. luminol directly. A possible reaction mechanism is proposed by the study of CL spectrum, UV-visible absorption spectra, ESR spectra as well as radical scavenging experiments The presence of BP QDs significantly increases generation of active oxygen species, which oxidize luminol and lead to intense CL emission at 425 nm. The reaction of luminol with BP QDs are specifically catalyzed by cobalt (II) ion, this presents a sensitive CL method for cobalt (II) ion. A linear response range extends from 2.5 to 2000.0 pmol/L cobalt (II) ion and a detection limit of 0.7 pmol/L (3s_b) is acquired. The method displays a good precision approved by a relative standard deviation of 1.9% at 100.0 pmol/L cobalt (II) ion solution (n = 11). A preliminary application of the method was conducted by successful determination of cobalt amount in silica gel and rain water samples.
