Li, Tiantian;Huang, Yu;Wei, Gaoliang;Zhang, Ya-nan;Zhao, Yuanhui;Crittenden, John C.;Li, Chao research published 《 Quantitative structure-activity relationship models for predicting singlet oxygen reaction rate constants of dissociating organic compounds》, the research content is summarized as follows. As singlet oxygen (¹O₂) is ubiquitous in the environment, ¹O₂-involved oxidation may play an important role in the transformation and fate of organic pollutants. Accordingly, the reaction rate constants (k_1O2) of organic compounds with ¹O₂ are important to determine the environmental fate and persistence assessment of organic pollutants. However, currently there are limited k_1O2 data available, especially for organic chems. with different charged (deprotonated/protonated) forms. Herein three quant. structure-activity relationship (QSAR) models (one comprehensive model and two models for neutral and deprotonated mols.) were created for predicting aqueous k_1O2 values for diversely dissociating mols. The models include larger datasets (180 chems.) and have wider applicability domain than previous ones. Mol. structural characteristics (only half-wave potential is present in both models) determining the ¹O₂ reaction rate of neutral and deprotonated mols. vary greatly. The comparison results of predicting k_1O2 values of organic compounds at certain pH conditions show that the combination of the QSAR models for neutral and deprotonated mols. has advantages over the comprehensive QSAR model. This work is the first study to predict k_1O2 for a wide variety of neutral and deprotonated mols. and provides an important tool for assessing the fate of organic pollutants in aquatic environments.

Li, Qianqian;Huang, Xinchen;Su, Guijin;Zheng, Minghui;Huang, Chunhua;Wang, Mengjing;Ma, Chunyan;Wei, Da research published 《 The Regular/Persistent Free Radicals and Associated Reaction Mechanism for the Degradation of 1,2,4-Trichlorobenzene over Different MnO₂ Polymorphs》, the research content is summarized as follows. The role of regular/persistent free radicals on the catalytic activity of K⁺-tuned MnO₂ tunnel structures is poorly understood to date. Herein, three MnO₂ polymorphs (α-, β-, and δ-MnO₂) were synthesized and examined toward the degradation of 1,2,4-trichlorobenzene (1,2,4-TrCBz) at 300 °C. δ-MnO₂, with a two-dimensional-layered tunnel structure tuned by K⁺, exhibited the highest activity among the three MnO₂ polymorphs. The ESR spectroscopy results confirmed that δ-MnO₂ featured the most abundant reactive oxygen species (ROS: O₂^-•, •OH, and ¹O₂), followed by α-MnO₂ (O₂^-• and ¹O₂), and β-MnO₂ (O₂^-•), being supported by the calculated energy barrier. It was, intriguingly, noted that persistent organic free radicals, newly recognized as emerging surface-stabilized compound, were remarkably detected in α- and β-MnO₂/1,2,4-TrCBz systems but not in more reactive δ-MnO₂/1,2,4-TrCBz system. These might contribute to discrepant oxidative degradation process. During the oxidative process, intermediates, including benzoic acid and glycerol, formed via attack by ROS. Upon further attack, these intermediates fragmented into smaller mols. such as formic, acetic, propionic, and butyric acids. The present findings give deeper insights into the role of free radicals on the catalytic degradation of chlorinated aromatics

Aberrant hyperactivation of cyclins results in carcinogenesis and therapy resistance in cancers. Direct degradation of the specific cyclin or cyclin-dependent kinase (CDK)-cyclin complex by small-mol. degraders remains a great challenge. Here, we applied the first application of hydrophobic tagging to induce degradation of CDK9-cyclin T1 heterodimer, which is required to keep productive transcription of oncogenes in cancers. LL-K9-3 (I) was identified as a potent small-mol. degrader of CDK9-cyclin T1. Quant. and time-resolved proteome profiling exhibited LL-K9-3-induced selective and synchronous degradation of CDK9 and cyclin T1. The expressions of androgen receptor (AR) and cMyc were reduced by LL-K9-3 (I) in 22RV1 cells. LL-K9-3 (I) exhibited enhanced anti-proliferative and pro-apoptotic effects compared with its parental CDK9 inhibitor SNS032 and suppressed downstream signaling of CDK9 and AR more effectively than SNS032. Moreover, LL-K9-3 (I) inhibited AR and Myc-driven oncogenic transcriptional programs and exerted stronger inhibitory effects on several intrinsic target genes of AR than the monomeric CDK9 PROTAC (Thal-SNS032).

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.

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, Chenxu;Wu, Jiaen;Peng, Wei;Fang, Zhendong;Liu, Jie research published 《 Peroxymonosulfate activation for efficient sulfamethoxazole degradation by Fe₃O₄/β-FeOOH nanocomposites: Coexistence of radical and non-radical reactions》, the research content is summarized as follows. 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.

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.
