| 1 | Recent advances in metal-organic framework-based materials for anti-staphylococcus aureus infection显示文摘The rapid spread of staphylococcus aureus(S.aureus)causes an increased morbidity and mortality,as well as great economic losses in the world.Anti-S.aureus infection becomes a major challenge for clinicians and nursing professionals to address drug resistance.Hence,it is urgent to explore high efficiency,low toxicity,and environmental-friendly methods against S.aureus.Metal-organic frameworks(MOFs)represent great potential in treating S.aureus infection due to the unique features of MOFs including tunable chemical constitute,open crystalline structure,and high specific surface area.Especially,these properties endow MOF-based materials outstanding antibacterial effect,which can be mainly attributed to the continuously released active components and the exerted catalytic activity to fight bacterial infection.Herein,the structural characteristics of MOFs and evaluation method of antimicrobial activity are briefly summarized.Then we systematically give an overview on their recent progress on antibacterial mechanisms,metal ion sustained-release system,controlled delivery system,catalytic system,and energy conversion system based on MOF materials.Finally,suggestions and direction for future research to develop and mechanism understand MOF-based materials are discussed in antibacterial application. | Mei Yang Jin Zhang Yinhao Wei Jie Zhang Chuanmin Tao | 2022 | Nano Research2022，15，7： | 2 |
| 2 | Enhanced degradation of organic contaminants by Fe(Ⅲ)/peroxymonosulfate process with L-cysteine显示文摘The difficulty in Fe(Ⅲ)/Fe(Ⅱ) conversion in the Fe(Ⅲ)/peroxymonosulfate(PMS) process limits its efficiency and application.Herein,L-cysteine(Cys),a green natural organic ligand with reducing capability,was innovatively introduced into Fe(Ⅲ)/PMS to construct an excellent Cys/Fe(Ⅲ)/PMS process.The Cys/Fe(Ⅲ)/PMS process,at room temperature,can degrade a variety of organic contaminants,including dyes,phenolic compounds,and pharmaceuticals.In subsequent experiments with acid orange 7(A07),the AO7 degradation efficiency followed pseudo-first-order kinetic which exhibited an initial 'fast stage' and a second 'slow stage'.The rate constant values ranged depending on the initial Cys,Fe(Ⅲ),PMS,and AO7 concentrations,reaction temperature,and pH values.In addition,the presence of Cl^(-),NO_(3)^(-),and SO_(4)^(2-) had negligible impact while HCO_(3)^(-) and humic acid inhibited the degradation of AO7.Furthermore,radical scavenger experiments and methyl phenyl sulfoxide(PMSO) transformation assay indicated that sulfate radical,hydroxyl radical,and ferryl ion(Fe(Ⅳ)) were the dominant reactive species involved in the Cys/Fe(Ⅲ)/PMS process.Finally,based on the results of gas chromatography-mass spectrometry,several AO7 degradation pathways,including N=N cleavage,hydroxylation,and ring opening were proposed.This study provided a new insight to improve the efficiency of Fe(Ⅲ)/PMS process by accelerating Fe(Ⅲ)/Fe(Ⅱ)cycle with Cys. | Chengdu Qi Yanni Wen Yijie Zhao Yinhao Dai Yanping Li Chenmin Xu Shaogui Yang Huan He | 2022 | Chinese Chemical Letters2022，33，4： | 1 |
| 3 | Coordinated Optimization of Multi-energy Generation Systems Considering the Health Damages of Coal-fired Pollutant Dispersion显示文摘Pollutants emitted from coal-fired power plants lead to the deterioration of air quality in developing countries,and contribute to both mortality and morbidity.To improve air quality from power generation,new dispatch strategies incorporated with air pollution dispersion models should be considered.This paper takes into account the impact of meteorological variations on spatio-temporal dispersion of pollutants.Depending on the coal-fired pollutant concentration estimated by the Gaussian plume dispersion model,exposure-response functions are used to quantify the resulting health effects.Furthermore,the corresponding economic costs of health damages are incorporated to penalize the power dispatch.Considering generation costs and economic costs of health damages,this paper formulates a twostage stochastic optimization model of a multi-energy generation system including coal units,gas units,and photovoltaic stations.Finally,numerical studies based on a modified IEEE 14-node system are performed for illustration and validation. | Suhua Lou Yinhao Yang Yanjie Liang Yaowu Wu | 2022 | CSEE Journal of Power and Energy Systems2022，8，6： | 0 |
