Frontiers of Chemical Science and Engineering 2018年第4期12卷 593-597页

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

Magnesium alloys are widely used as shells of 3C (computer, mobile phone and consumer electronics) equipments for its impressive mechanical and physical properties, such as low density, good resistance to electromagnetic radiation, suitable for high pressure diecasting and easily recycling, etc. But poor corrosion resistance confines its extensively application. In this paper, protective coatings was successfully prepared on AZ91D magnesium alloys by micro-arc oxidation (MAO) and painting process. Microstructures and phases of MAO coatings were invesgated with scanning electron microscope (SEM) and X-Ray diffractometer. Mechanical properties of MAO coating, such as adhesive force and corrosion resistance, were also tested. Results showed that MAO coatings were a good base for painting process. MAO coatings with paint have good adhesive properties to base metal and excellent corrosion resistance. Micro-arc oxidation with painting process is a good kind of surface treatment to improve the corrosion resistance of mobile phone shell made of AZ91D magnesium alloys.
