Objective To investigate the effect of chemical oxygen demand （COD） concentrations on the anaerobic ammonium oxidation （ANAMMOX）. Methods An Expanded Granular Sludge Bed （EGSB） reactor was used to cultivate the granular sludge and to perform the ANAMMOX reaction in the bench scale experiment. NH4^＋-N and NO2^--N were measured by using colorimetric method. NO3^＋-N was analyzed by using the UV spectrophotometric method. COD measurement was based on digestion with potassium dichromate in concentrated sulphuric acid. Results When the COD concentrations in the reactors were 0 mg/L, 200 mg/L, 350 mg/L, and 550 mg/L, respectively, the NH4^＋-N removal efficiency was 12.5%, 14.2%, 14.3%, and 23.7%; the removal amount of NO2-N was almost the same; the nitrate removal efficiency was 16.8%, 94.5%, 86.6%, and 84.2% and TN removal efficiency was 16.3%, 50.7%, 46.9%, and 50.4%, moreover, the COD removal efficiency was 85%, 65.7%, and 60%; the COD removal rate was 27.42, 61.88, and 97.8 mg COD/（h·L）. Conclusion COD concentrations have a significant influence on anaerobic ammonium oxidation by granular sludge.

The fronts of a subject could be perceived from the publications of top journals. We investigated four top journals on chemical engineering: AIChE Journal, Chemical Engineering Science, Industrial & Engineering Chemistry Research and Chemical Engineering Journal. Based on Web of Science, in the last five years, these four journals have published 21062 papers, including 590 highly cited papers and 31 “hot” papers among which only 7 are from Industrial & Engineering Chemistry Research and all the others from Chemical Engineering Journal (data obtained on November 17, 2018). The traditional research “Pure and pseudo-pure fluid thermophysical property evaluation and the open-source thermophysical property library CoolProp” is the most cited paper published in 2014 [1]. Both highly cited and “hot” papers were published in 2017 on electrodes of supercapacitors [2]. But researches on environmental science and engineering have been paid most attention with 17 of 27 both highly cited and “hot” papers on this research area. The most cited and “hottest” paper is “Boron nitride-based materials for the removal of pollutants from aqueous solutions: A review” in 2018 [3]. Over the past decades, research and technologies advancement in chemical science and engineering in China has expanded in a lightning speed globally. To meet the growing needs of knowledge exchange and understanding of the underlying scientific principles, we launched in 2007 a new journal named Frontiers of Chemical Engineering in China with all papers translated from the Chinese journals. Original research articles or reviews have been published since 2009. The new name Frontiers of Chemical Science and Engineering (FCSE) has begun only since 2011 and FCSE became one of the Transactions of the Chinese Academy of Engineering (CAE) in 2014. From CAE, we have received many supports, both academic and financial. Especially in the latest three years, we have organized some important Special Issues and Topics. For th

Ischemic stroke is increasing worldwide, and stent intervention has gradually become one of the effective treatments. Owing to its good mechanical properties and biocompatibility, biodegradable Mg-Zn-Y-Nd alloy(ZE21B) has good application prospects in vascular ***, too fast degradation and delayed endothelialization are the bottleneck problem to limit its further application. In this study, the bio-inspired coating barnacle cement cp19k is constructed on ZE21B surface through electrostatic spraying to improve the corrosion resistance and pro-endothelialization ability. The coating was evaluated through electrochemistry, static immersion corrosion,in vitro blood experiments and cell experiments. Cp19k effectively improved the corrosion resistance of the substrate ZE21B, reduced the degradation rate, improved endothelial cell proliferation and migration capabilities,inhibited smooth muscle cells proliferation and regulated contractile phenotype, inhibited macrophage adhesion,regulated macrophage M2 phenotype, and reduced the expression of inflammatory factor of TNF-a and inhibited fibroplasia in vivo. Our data indicated that the barnacle cement cp19k coating had potential application on the surface modification of Mg alloy cerebrovascular stent.

When high-temperature steam is used as a medium to pyrolyze organic-rich shale,water steam not only acts as heat transfer but also participates in the chemical reaction of organic matter pyrolysis,thus affecting the generation law and release characteristics of gas *** this study,based on a long-distance reaction system of organic-rich shale pyrolysis via steam injection,the effects of steam temperature and reaction distance on gas product composition are analyzed in depth and compared with other pyrolysis *** advantages of organic-rich shale pyrolysis via steam injection are then *** volume concentration of hydrogen in the gas product obtained via the steam injection pyrolysis of organic-rich shale is the highest,which is more than 60%.The hydrogen content increases as the reaction distance is extended;however,the rate of increase changes *** the reaction distance from 800 to 4000 mm increases the hydrogen content from 34.91%to 69.68%and from 63.13%to 78.61%when the steam temperature is 500℃ and 555℃,***,the higher the heat injection temperature,the smaller the reaction distance required to form a high concentration hydrogen pyrolysis environment(hydrogen concentration>60%).When the steam pyrolysis temperature is increased from 500℃ to 555℃,the reaction distance required to form a high concentration of hydrogen is reduced from 3800 to 800 *** with the direct retorting process,the volume concentration of hydrogen obtained from high-temperature steam pyrolysis of organic-rich shale is 8.82 and 10.72 times that of the commonly used Fushun and Kivite furnaces,*** pyrolysis of organic-rich shale via steam injection is a pyrolysis process in a hydrogen-rich environment.
