Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published.The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic.The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts.Areas of interest include (but are not limited to): 1. Nanotechnology 2. Energy and environmental engineering 3. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 4. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 5. Process systems engineering 6. Reaction engineering and catalysis.Selection of the topics to be reviewed: Targeted topics and guest editors of special collections are proposed by the editors and editorial board members. The topics are selected to include emerging areas of high importance, and to comprehensively cover topics within the scope of the journal. The published collections are expected to make a high impact to the scientific community and the field. Each issue of the journal will focus on two themed collections.Editorial Overview: Guest Editors write a short overview at the beginning of the section to introduce the reviews and to draw the reader's attention to any particularly interesting developments.
