Gao, Yaowen;Zhu, Yue;Chen, Zhenhuan;Hu, Chun research published 《 Nitrogen-Coordinated Cobalt Embedded in a Hollow Carbon Polyhedron for Superior Catalytic Oxidation of Organic Contaminants with Peroxymonosulfate》, the research content is summarized as follows. The search for high-active and long-lasting materials is of paramount significance for elimination of aqueous organic contaminants. Herein, a nitrogen-coordinated cobalt embedded in hollow carbon polyhedron (marked as NCoHCP) has been synthesized by thermal transformation of core-shell-architectured ZIF-8@ZIF-67. XPS, X-ray absorption spectroscopy (XAS), and theor. calculations confirmed the coordination of a Co atom with one N atom in NCoHCP. The resultant NCoHCP catalyst delivers extremely superior catalytic performance in peroxymonosulfate (PMS) decomposition into active species toward complete oxidation of organic pollutants in less than 45 s. Exptl. data and theor. computations disclosed the formation of Co-pyridinic N moiety not only creates the Co species with higher electron d. as active sites but also increases the C atom neighboring pyridinic N with lower electron d. as binding sites for PMS conversion toward reactive oxygen species generation to oxidize organic pollutant. On the other hand, the donation of electron from organic contaminant toward the C atom adjacent to pyridinic N also induces organic contaminant oxidation The dual-pathway degradation contributes to superior catalytic oxidation of organics over NCoHCP. This study furnishes an effective strategy for developing high-performance and robust metal/carbon hybrid materials toward wide environmental applications.

Gao, Yaowen;Zhu, Yue;Li, Tong;Chen, Zhenhuan;Jiang, Qike;Zhao, Zhiyu;Liang, Xiaoying;Hu, Chun research published 《 Unraveling the high-activity origin of single-atom iron catalysts for organic pollutant oxidation via peroxymonosulfate activation》, the research content is summarized as follows. Single-atom catalysts (SACs) have emerged as efficient materials in the elimination of aqueous organic contaminants; however, the origin of high activity of SACs still remains elusive. Herein, we identify an 8.1-fold catalytic specific activity (reaction rate constant normalized to catalyst’s sp. surface area and dosage) enhancement that can be fulfilled with a single-atom iron catalyst (SA-Fe-NC) prepared via a cascade anchoring method compared to the iron nanoparticle-loaded catalyst, resulting in one of the most active currently known catalysts in peroxymonosulfate (PMS) conversion for organic pollutant oxidation Exptl. data and theor. results unraveled that the high-activity origin of the SA-Fe-NC stems from the Fe-pyridinic N₄ moiety, which dramatically increases active sites by not only creating the electron-rich Fe single atom as the catalytic site but also producing electron-poor carbon atoms neighboring pyridinic N as binding sites for PMS activation including synchronous PMS reduction and oxidation together with dissolved oxygen reduction Moreover, the SA-Fe-NC exhibits excellent stability and applicability to realistic industrial wastewater remediation. This work offers a novel yet reasonable interpretation for why a small amount of iron in the SA-Fe-NC can deliver extremely superior specific activity in PMS activation and develops a promising catalytic oxidation system toward actual environmental cleanup.

Ge, Jiali;Wang, Xinghao;Li, Chenguang;Wang, Siyuan;Wang, Lianhong;Qu, Ruijuan;Wang, Zunyao research published 《 Photodegradation of polychlorinated diphenyl sulfides mediated by reactive oxygen species on silica gel》, the research content is summarized as follows. Polychlorinated di-Ph sulfides (PCDPSs) are a group of dioxin-like compounds that have been widely used in agricultural and industrial productions. Here, we systematically investigated the photochem. behaviors of 2,2′,3′,4,5-pentachlorodiphenyl sulfide (2,2′,3′,4,5-PCDPS) on the surface of silica gel (SG) in an aqueous environment. Under the simulated sunlight irradiation, 2,2′,3′,4,5-PCDPS adsorbed on SG (0.11 mg/g) was found to be degraded with time, giving a removal rate of 68.5% within 16 h at pH 7.0. Environmental factors like pH and humic acid can also affect the removal rate. Results showed that the removal rate of 2,2′,3′,4,5-PCDPS in alk. conditions (75.6% at pH 11) was higher than that in acidic conditions (46.7% at pH 3). Moreover, the addition of (1-5 mg/L) humic acid can promote the degradation rate compared to control group. In our study, it was found that SG can act as photocatalyst to generate reactive oxygen species (ROS) for the degradation of PCDPSs, and UV light contributed much more than visible light (>420 nm). According to ESR (EPR) technol. and radicals quenching experiments, hydroxyl radical (·OH), single oxygen (¹O₂), and superoxide radical (·O^–₂) participated in the removal of the contaminant. Based on the identified intermediate products via LC-MS, two main pathways, i.e., the hydroxyl-substituted reaction of the benzene ring and the oxidation of the sulfur atom, were proposed for the photodegradation of 2,2′,3′,4,5-PCDPS. Then, the d. functional theory (DFT) was employed to confirm these reaction pathways. This study would enhance the understanding of the photochem. transformation and environmental fate of PCDPSs on the surface of solids in natural waters.

Ghanbar, Sadegh;Kazemian, Mohammad Reza;Liu, Song research published 《 New Generation of N-Chloramine/QAC Composite Biocides: Efficient Antimicrobial Agents To Target Antibiotic-Resistant Bacteria in the Presence of Organic Load》, the research content is summarized as follows. We previously reported that covalently joining an amide-based N-chloramine with a quaternary ammonium compound (QAC) can yield a new composite biocide with faster inactivation of various bacteria. Importantly, the composite biocide was found to reduce the risk for potential bacterial resistance associated with QAC. However, similar to other N-chloramines and QACs, this high-performance composite biocide becomes less potent against pathogenic bacteria in the presence of high protein fluids. In this study, we substituted the amide-based N-chloramine moiety in the previously reported composite biocide with a secondary amine-based N-chloramine to improve the biocidal efficacy in biol. fluids. The N-Cl bond in the synthesized tetramethylpiperidine-based composite biocides is more stable in a high protein medium (HPM) than that in the hydantoin (amide)-based composite biocides. The composite biocide, 2-[4-(1-chloro-2,2,6,6-tetramethyl-piperidin-4-yloxymethyl)-[1,2,3]triazol-1-yl]-ethyl-dodecyl-dimethyl-ammonium chloride (6a), showed the best antibacterial activity in both phosphate-buffered saline and HPM among various composite biocides and benzyldodecyldimethylammonium chloride used in this study.

Guo, Dongli;Liu, Yanbiao;Ji, Haodong;Wang, Chong-Chen;Chen, Bo;Shen, Chensi;Li, Fang;Wang, Yongxia;Lu, Ping;Liu, Wen research published 《 Silicate-enhanced heterogeneous flow-through electro-Fenton system using iron oxides under nanoconfinement》, the research content is summarized as follows. Herein, a silicate-enhanced flow-through electro-Fenton system with a nanoconfined catalyst was rationally designed and demonstrated for the highly efficient, rapid, and selective degradation of antibiotic tetracycline. The key active component of this system is the Fe₂O₃ nanoparticle filled carbon nanotube (Fe₂O₃-in-CNT) filter. Under an elec. field, this composite filter enabled in situ H₂O₂ generation, which was converted to reactive oxygen species accompanied by the redox cycling of Fe³⁺/Fe²⁺. The presence of the silicate electrolyte significantly boosted the H₂O₂ yield by preventing the O-O bond dissociation of the adsorbed OOH*. Compared with the surface coated Fe₂O₃ on the CNT (Fe₂O₃-out-CNT) filter, the Fe₂O₃-in-CNT filter demonstrated 1.65 times higher k_L value toward the degradation of the antibiotic tetracycline. ESR and radical quenching tests synergistically verified that the dominant radical species was the ¹O₂ or HO· in the confined Fe₂O₃-in-CNT or unconfined Fe₂O₃-out-CNT system, resp. The flow-through configuration offered improved tetracycline degradation kinetics, which was 5.1 times higher (at flow rate of 1.5 mL min^-1) than that of a conventional batch reactor. Liquid chromatog.-mass spectrometry measurements and theor. calculations suggested reduced toxicity of fragments of tetracycline formed. This study provides a novel strategy by integrating state-of-the-art material science, Fenton chem., and microfiltration technol. for environmental remediation.

While biochar supported iron materials have been widely studied in advanced oxidation processes (AOPs), little is known about the effect and mechanism of goethite/biochar in sulfate radical (SO₄^–) based AOPs. Herein, a novel goethite/biochar composite was applied as peroxymonosulfate (PMS) activator for tetracycline (TC) degradation in the water. The superior catalytic efficiency of goethite/biochar was achieved through radical (·OH and SO₄^–) and non-radical (¹O₂) processes according to the radicals quenching experiments and ESR anal. Carbonyl group and Fe species were the main active sites on the surface of goethite/biochar, which was demonstrated by combining Fourier transform IR spectroscopy, XPS and reaction kinetic experiments Furthermore, nine main byproducts of TC degradation were detected by liquid chromatog.-mass spectrometry and the reasonable degradation pathway was proposed according to the mol. structure anal. Overall, the goethite/biochar materials could be applied to activate PMS for TC degradation, and this study will benefit the application of iron/biochar materials in practical water treatment.

In this study, the performance of periodate (PI) on sulfadiazine (SDZ) degradation was evaluated using coagulation solid waste fabricated catalyst (CWBC), obtained by simple pyrolysis. SDZ effectively underwent 98.94% remove within 90 min in the CWBC/PI system. Electron transfer was the predominant mechanism due to the development of an electronic cycle among SDZ, CWBC and PI, where the O·-2, PFRs, and the reactive iodine species had minor roles. D. functional theory calculations identified that Fe and N could change the electron configuration and break the chem. inertness of carbonaceous material. As a result, electrons on the carbon matrix of CWBC are inclined to travel through the formed Fe-O covalent bond to PI. Further anal. demonstrated that SO2-4, humic acid (HA), as well as anoxic conditions greatly facilitated SDZ degradation This study provides a facile protocol for converting coagulation waste to an efficient catalyst and provides fundamental insights into the degradation mechanisms of micropollutants by activating PI.

Hinoshita, Masumi;Abe, Takayuki;Sato, Asako;Maeda, Yosuke;Takeyoshi, Masahiro research published 《 Development of a new photosafety test method based on singlet oxygen generation detected using electron spin resonance》, the research content is summarized as follows. Photosafety evaluations of chems. used in consumer products, such as pharmaceuticals and cosmetics, are very important. Currently, two non-animal tests for photosafety evaluations, the in vitro 3T3 neutral red uptake phototoxicity test (NRU PT) and the reactive oxygen species (ROS) assay, are used to detect photoreactive chems. However, these two tests are difficult to apply to hydrophobic chems. In the present study, we attempted to develop a new photosafety test method, named the ESR-based photosafety test (ESR-PT), that would be applicable even to hydrophobic chems. based on the detection of singlet oxygen generation after irradiation using ESR spectroscopy with 4-hydroxy-2,2,6,6-tetramethyl-piperidine as a spin trap reagent. To achieve a quant. evaluation, the singlet oxygen formation (SOF) value, which can be calculated as the increment in relative intensity after irradiation of the test mixture normalized by the increment in relative intensity after irradiation of the vehicle control solution, was calculated Therefore, the SOF value could be an effective parameter for photosafety evaluations, suggesting that the newly developed ESR-PT is a promising non-animal test applicable even to hydrophobic chems.

Spinal muscular atrophy (SMA), a rare neuromuscular disorder, is the leading genetic cause of death in infants and toddlers. SMA is caused by the deletion or a loss of function mutation of the survival motor neuron 1 (SMN1) gene. In humans, a second closely related gene SMN2 exists, however it codes for a less stable SMN protein. In recent years, significant progress has been made toward disease modifying treatments for SMA by modulating SMN2 pre-mRNA splicing. Herein, we describe the discovery of LMI070/branaplam, a small mol. that stabilizes the interaction between the spliceosome and SMN2 pre-mRNA. Branaplam (1) originated from a high-throughput phenotypic screening hit, pyridazine 2, and evolved via multi-parameter lead optimization. In a severe mouse SMA model, branaplam treatment increased full-length SMN RNA and protein levels, and extended survival. Currently, branaplam is in clin. studies for SMA.

Abstract: HSV disease is distributed worldwide. Anti-herpesvirus drugs are a problem in clin. settings, particularly in immunocompromised individuals undergoing herpes simplex virus type 1 infection. In this work, 4-substituted-1,2,3-1H-1,2,3-triazole linked nitroxyl radical derived from TEMPOL were synthesized, and their ability to inhibit the in vitro replication of HSV-1 was evaluated. The nitroxide derivatives were characterized by IR spectroscopy and elemental anal., and three of them had their crystal structures determined by single-crystal X-ray diffraction. Four hybrid mols. showed important anti-HSV-1 activity with IC₅₀ values ranged from 0.80 to 1.32μM. In particular, one of the nitroxide derivatives was more active than Acyclovir (IC₅₀ = 0.99μM). All compounds tested were more selective inhibitors than the reference antiviral drug. Among them, two compounds were 4.5 (IC₅₀ 0.80μM; selectivity index CC₅₀/IC₅₀ 3886) and 7.7 times (IC₅₀ 1.10μM; selectivity index CC₅₀/IC₅₀ 6698) more selective than acyclovir (IC₅₀ 0.99μM; selectivity index CC₅₀/IC₅₀: 869). These nitroxide derivatives may be elected as leading compounds due to their antiherpetic activities and good selectivity.
