| 1 | Carbamazepine degradation by heterogeneous activation of peroxymonosulfate with lanthanum cobaltite perovskite:Performance,mechanism and toxicity显示文摘The widely used carbamazepine(CBZ)is one of the most persistent pharmaceuticals and suffers insufficient removal efficiency by conventional wastewater treatment.A synthesized Co-based perovskite(LaCoO3)was used to activate peroxymonosulfate(PMS)in order to degrade CBZ.Results showed that LaCoO3 exhibited an excellent performance in PMS activation and CBZ degradation at neutral pH,with low cobalt leaching.The results of FT-IR and XPS verified the high structurally and chemically stability of LaCoO3 in PMS activation.Electron spin resonance(ESR)analysis suggested the generation of radical species,such as sulfate radicals(SO4·-)and hydroxyl radicals(·OH).Radical quenching experiments further revealed the responsibility of SO4·-as the dominant oxidant for CBZ oxidation.Ten products were detected via the oxidation of CBZ,with the olefinic double bond attacked by SO4·-as the initial step.Hydroxylation,hydrolysis,cyclization and dehydration were involved along the transformation of CBZ.The toxicity of CBZ solution was significantly reduced after treating by PMS/LaCoO3. | Huichao Guo Xuefei Zhou Yalei Zhang Qiufang Yao Yajie Qian Huaqiang Chu Jiabin Chen | 2020 | Journal of Environmental Sciences2020，32，5： | 4 |
| 2 | Evaluation of humic acid removal by a flat submerged membrane photoreactor显示文摘A flat submerged membrane combined with a TiO 2 /UV photocatalytic reactor (FSMPR) was employed in batch mode to remove humic acid (HA). HA removal efficiency was characterized by UV 254 absorbance, UV-vis spectra, dissolved organic carbon (DOC) concentration, specific UV absorbance (SUVA), and trihalomethane formation potential (THMFP). The FSMPR process was effective in removing more than 86% of DOC and nearly 100% of UV 254 absorbance, while the THMFPs of samples were reduced to < 19 μ g/L after 150 min of treatment. In addition, changes in transmembrane pressure (TMP) with and without UV were evaluated; TiO 2 /UV was effective at controlling membrane fouling by HA. Analysis of the molecular weight (MW) distributions and three-dimensional excitation-emission matrix (EEM) fluorescence spectra of HAs revealed that the effectiveness in membrane fouling control is a result of changes in HA molecular characteristics. The TiO 2 /UV photocatalytic reactor caused the degradation of high MW, hydrophobic humic-like molecules to low MW, hydrophilic protein-like molecules, although this fraction was not completely removed during 150 min of treatment and was less responsible for membrane fouling. | WEI Yong CHU HuaQiang DONG BingZhi LI Xuan | 2011 | Chinese Science Bulletin2011，56，32： | 3 |

| 4 | Characterization of dissolved organic matter in a dynamic membrane bioreactor for wastewater treatment显示文摘This paper systematically examined the characteristics of dissolved organic matter(DOM) in a dynamic membrane bioreactor(DMBR) for municipal wastewater with a laboratory-scale continuous-flow device.Experimental results showed that the system performed excellent pollutants' removal efficiencies.The increase of trans-membrane pressure(TMP) for the dynamic membrane(DM) could be divided into three stages,i.e.,zero increase stage,slow increase stage and abrupt rise stage.The maximal fouling rate of the DM reached to 4.34 kPa/h in abrupt rise stage.It was observed that the polysaccharides(PS) concentration of DOM samples gradually increased from the anaerobic zone to the aerobic zone in sequence,but the proteins(PN) concentration performed an opposite trend.The DM could retain a small part of the large molecular substances(>10 kDa) in the aerobic zone.Two particular fluorescence peaks appeared in the anaerobic zone and in the anoxic zone were also found in the effluent,which illustrated the dynamic cake layer closed to the stainless steel mesh might induce an anaerobic/anoxic micro environment.Based on the three-dimensional excitation-emission matrix(EEM) fluorescence spectroscopy analysis,aromatic proteins,aromatic proteinlike substance,fulvic acid-like substances and soluble microbial by-product-like materials could be biodegraded effectively in the DMBR,and the DM could partly remove the humic acid-like substances and soluble microbial by-product-like materials. | ZHANG YaLei ZHANG Hai CHU HuaQiang ZHOU XueFei ZHAO YangYing | 2013 | Chinese Science Bulletin2013，58，15： | 1 |

| 12 | Ligand engineering of colloid quantum dots and their application in all-inorganic tandem solar cells显示文摘How to effectively utilize the energy of the broad spectrum of sunlight is one of the basic problems in the research of tandem solar cells. Due to their size effect, quantum confinement effect and coupling effect, colloidal quantum dots(QDs) exhibit new physical properties that bulk materials don’t possess.CdX(X = Se, S, etc.) and Pb X(X = Se, S, etc.) QDs prepared by hot-injection methods have been widely studied in the areas of photovolitaic devices. However, the surfactants surrounding QDs seriously hinder the charge transport of QDs based solar cells. Therefore, how to fabricate high-performance tandem solar cells via ligands engineering has become a major challenge. In this paper, the latest progress of colloidal QDs in the research of all-inorganic tandem solar cells was summarized. Firstly, the improvement of QDs surface ligands and the optimization of ligands engineering were discussed, and the control of the physical properties of QDs films were realized. From the aspects of colloidal QDs, ligand engineering, and solar cell preparation, the future development direction of colloidal QDs solar cells was proposed, providing technical guidances for the preparation of low-cost and high-efficiency nanocrystalline solar cells. | Fen Qiao Yi Xie Zhankun Weng Huaqiang Chu | 2020 | Journal of Energy Chemistry2020，29，11： | 1 |

| 18 | κ-Opioid receptor activation attenuates osteoarthritis synovitis by regulating macrophage polarization through the NF-κB pathway显示文摘Osteoarthritis(OA)is a prevalent and chronic joint disease that affects the aging population,causing pain and disability.Macrophages in synovium are important mediators of synovial inflammatory activity and pathological joint pain.Previous studies have demonstrated the significant involvement of k-opioid receptor(KOR)in the reg-ulation of pain and inflammation.Our study reveals a significant reduction in synovial KOR expression among patients and mice with OA.Here,we find that KOR activation effectively inhibits the expressions of the LPS-induced-inflammatory cytokines TNF-αand IL-6 by inhibiting macrophage M1 phenotype.Mechanistically,KOR activation effectively suppresses the proinflammatory factor secretion of macrophages by inhibiting the translocation of NF-kB into the nucleus.Our animal experiments reveal that activation of KOR effectively alleviates knee pain and prevents synovitis progression in OA mice.Consistently,KOR administration suppresses the expressions of M1 macrophage markers and the NF-kB pathway in the synovium of the knee.Collectively,our study suggests that targeting KOR may be a viable strategy for treating OA by inhibiting synovitis and improving joint pain in affected patients. | Yi Shi Huaqiang Tao Xueyan Li Liyuan Zhang Chunhui Li Wen Sun Miao Chu Kai Chen Pengfei Zhu Qiang Wang Chengyong Gu Liangliang Wang Xing Yang Yuefeng Hao | 2024 | Acta Biochimica et Biophysica Sinica2024，56，1： | 0 |

| 20 | Dynamic Analysis of Bubble Attachment and Sweeping on Microwire in Subcooled Nucleate Pool Boiling显示文摘With the development of industrial technology,heat transfer at the microscale has attracted more and more attention.In this work,200μm platinum wire and 150μm nickel-chromium wire were used as experimental objects,which the power was provided by DC power with the range of 15.6 W to 56.2 W.Distilled water was used as the experimental liquid.Various bubbles on the micro wire were observed and the heat mechanism was analyzed.A variety of bubble attachment phenomena were captured on the 200μm platinum wire,including the adhesion during bubble detachment,the rotation of small attached bubbles on the surface of large bubble,multiple bubbles circling at the top of the same bubble,and different attached bubble departure phenomena.Marangoni force in the vertical direction triggered the formation of bubble attachment.In addition,the effects of surface tension,adhesion force and buoyancy force on the circling of the bubble were also considered.The analysis of the bubble sweeping on the 150μm nickel-chromium wire was analyzed.The results showed that the static bubble would interact with the sweeping bubbles on the other side,thereby changing the heat transfer mechanism,which was not discussed in detail before.The bubble jet flow generated by thermocapillary convection on the vertical direction of the bubble surface was the main influencing factor,which would change the microlayer encountered in front of the bubble.The effects of bubble diameter and liquid subcooling on the sweeping velocity were also studied.The results showed that the larger the bubble diameter was,the lower the sweeping velocity would be achieved while the liquid subcooling temperature had less impact on the velocity of sweeping bubble. | XU Nian JIANG Hantao PENG Licheng WANG Dongdong CHU Huaqiang | 2021 | Journal of Thermal Science2021，30，5： | 0 |
