Our vision is of a world improved through the positive impact of research published in Chemical Engineering Science. Chemical Engineering is a critical force for a better future enabling humanity to address many of the global challenges we face. Affordable clean energy, clean water, responsible production, sustainable communities, and good health and well-being, all require advanced chemical engineering knowledge and its application. Our aim is to selectively publish outstanding research that has as its foundations the Scienceof Chemical Engineering. We welcome all top-shelf research in the continually evolvingdiscipline of chemical engineering. The Engineering Science section continues its long leadership of publishing importantdevelopments in the fundamentals of the discipline since 1951. The Catalysis, Green and Sustainable, Environmental and Novel Materials sections publishnovel, innovative, and high-impact applications of Chemical Engineering Science reported bychemical engineers and their allied peers.
