| 1 | Optimization of H_2O_2 dosage in microwave-H_2O_2 process for sludge pretreatment with uniform design method显示文摘A microwave-H2O2 process for sludge pretreatment exhibited high efficiencies of releasing organics,nitrogen,and phosphorus,but large quantities of H2O2 residues were detected.A uniform design method was thus employed in this study to further optimize H2O2 dosage by investigating effects of pH and H2O2 dosage on the amount of H2O2 residue and releases of organics,nitrogen,and phosphorus.A regression model was established with pH and H2O2 dosage as the independent variables,and H2O2 residue and releases of organics,nitrogen,and phosphorus as the dependent variables.In the optimized microwave-H2O2 process,the pH value of the sludge was firstly adjusted to 11.0,then the sludge was heated to 80°C and H2O2 was dosed at a H2O2:mixed liquor suspended solids(MLSS)ratio of 0.2,and the sludge was finally heated to 100°C by microwave irradiation.Compared to the microwave-H2O2 process without optimization,the H2O2 dosage and the utilization rate of H2O2 in the optimized microwave-H2O2 process were reduced by 80% and greatly improved by 3.87 times,respectively,when the H2O2:MLSS dosage ratio was decreased from 1.0 to 0.2,resulting in nearly the same release rate of soluble chemical oxygen demand in the microwave-H2O2 process without optimization at H2O2:MLSS ratio of 0.5. | Qingcong Xiao Hong Yan Yuansong Wei Yawei Wang Fangang Zeng Xiang Zheng | 2012 | Journal of Environmental Sciences2012，24，12： | 12 |
| 2 | Effect of organic matter on phosphorus recovery from sewage sludge subjected to microwave hybrid pretreatment显示文摘Microwave(MW) hybrid processes are able to disrupt the flocculent structure of complex waste activated sludge,and help promote the recovery of phosphorus as struvite.In this study,to optimize struvite yield,(1) the characteristics of matter released in MW-hybrid treatments were compared,including MW,MW-acid,MW-alkali,MW-H_2O_2,and MW-H_2O_2- alkali.The results showed that selective release of carbon,nitrogen,phosphorus,Ca^(2+),and Mg^(2+) achieved by sludge pretreatment using MW-hybrid processes.MW-H_2O_2 is the recommended sludge pretreatment process for phosphorus recovery in the form of struvite.The ratio of Mg^(2+):NH_4^+-N:PO_4^(3-)-P was 1.2:2.9:1 in the supernatant.(2) To clarify the effects of organic matter on struvite recovery,the composition and molecular weight distribution of organic matters were analyzed.Low molecular weight COD was found to facilitate the removal rate of NH_4^+-N and PO_4^(3-)P via crystallization,and the amorphous struvite crystals(<1 kDa) from the filtered solutions had high purity.Therefore,the present study reveals the necessity of taking into consideration the interference effect of high molecular weight organic matters during struvite crystallization from sewage sludge. | Yawei Wang Qingcong Xiao Hui Zhong Xiang Zheng Yuansong Wei | 2016 | Journal of Environmental Sciences2016，28，1： | 4 |
| 3 | 溶液相合成卤化石墨烯及其对氧化还原反应的电催化活性(英文)显示文摘Metal-free carbon electrocatalyts for the oxygen reduction reaction (ORR) are attractive for their high activity and economic advantages. However, the origin of the activity has never been clearly elucidated in a systematic manner. Halogen group elements are good candidates for elucidating the effect, although it has been a difficult task due to safety issues. In this report, we demonstrate the synthesis of Cl-, Br- and I-doped reduced graphene oxide through two solution phase syntheses. We have evaluated the effectiveness of doping and performed electrochemical measurements of the ORR activity on these halogenated graphene materials. Our results suggest that the high electroneg-ativity of the dopant is not the key factor for high ORR activity; both Br- and I-doped graphene promoted ORR more efficiently than Cl-doped graphene. Furthermore, an unexpected sulfur-doping in acidic conditions suggests that a high level of sulfide can degrade the ORR activity of the graphene material. | Kuang-Hsu Wu Da-Wei Wang Qingcong Zeng Yang Li Ian R.Gentle | 2014 | 催化学报2014，35，6： | 1 |

| 12 | Dimension reduction with expectation of conditional difference显示文摘In this article,we introduce a flexible model-free approach to sufficient dimension reduction analysis using the expectation of conditional difference measure.Without any strict conditions,such as linearity condition or constant covariance condition,the method estimates the central subspace exhaustively and efficiently under linear or nonlinear relationships between response and predictors.The method is especially meaningful when the response is categorical.We also studiedthe√n-consistency and asymptotic normality of the estimate.The efficacy of our method is demonstrated through both simulations and a real data analysis. | Wenhui Sheng Qingcong Yuan | 2023 | Statistical Theory and Related Fields2023，7，3： | 0 |

[Methods] Using Sanhuang chicken as the control,the GRX2 and TRX2 genes were cloned from skin tissues of Puerpiao chicken and Tengchongxue chicken and then subjected to bioinformatics analysis. [Results] The sequencing results of both the GRX2 and TRX2 genes were completely consistent among Puerpiao chicken,Tengchongxue chicken and Sanhuang chicken. And the sequences of GRX2 and TRX2 genes share a 100% homology with the results accessed in Gen Bank,and no any mutation was observed. [Conclusion]The result provides scientific basis for investigating the antioxidant capacity of different chickens and utilizing elite local chicken resources. | Fang Fang Zhang Chunyong Li Yanxuan Li Meiquan An Qingcong Chen Kelin Guo Rongfu | 2014 | Animal Husbandry and Feed Science2014，6，3： | 0 |
| 14 | Multi-Functional Supramolecular-Polymeric Hybrid Hydrogel for Promoting Cutaneous Wound Repair显示文摘Supramolecular-polymeric hybrid hydrogels combining advantages of the assembled supramolecular networks and polymeric networks have attracted considerable attention recently.However,they are rarely used as multi-functional wound dressing materials.In this work,we report a supramolecular-polymeric hybrid hydrogel consisting of a co-assembled DBS-COOH/Naproxen network(DBS/NAP)and a polymeric gelatin(G)/quaternary ammonium group(Q)and phenylboronic acid groups(PBA)-grafted chitosan(QCS-PBA)network(G/QCS)for accelerating skin wound healing.The polymeric networks could obviously enhance the mechanical properties of the drug-derived supramolecular networks.Q groups endowed the hydrogel with enhanced antibacterial properties.Borate ester crosslinking between PBA groups and diol groups in DBS-COOH could effectively scavenge reactive radicals.The hybrid hydrogel exhibited tunable mechanical and adhesive properties due to the temperature-responsive gelatin networks.NAP could gradually release from hybrid hydrogel networks thus continuously relieving inflammation.Finally,the biocompatible,adhesive,antibacterial and antioxidant hybrid G/QCS-DBS/NAP gel could promote the in vivo healing stages in a full-thickness wounds with increased collagen deposition,upregulated CD31 expression and down-regulated TNF-αexpression.Overall,this multi-functional supramolecular-polymeric hybrid hydrogel exhibited great potential for treating skin defects as promising wound dressing materials. | Qingcong Wei Liyang Jia Yuke Wang Weiwei Zhang Zhiguo Hu Qigang Wang Qing Wu | 2023 | Chinese Journal of Chemistry2023，41，20： | 0 |
