Professor Lina Zhang of Wuhan University, an Associate Editor for ACS Sustainable Chemistry & Engineering, passed away on October 17, 2020. Professor Zhang was a global leader in natural polymers. Her scientific achievements were remarkable. She pioneered low temperature technologies for processing of cellulose, chitin, and polyaniline (PANI) using green solvents. She constructed novel functional materials from these natural polymers and demonstrated their application. She was an author on more than 600 papers and 100 patents. The scientific quality of her work has been recognized globally. She was elected an academician of the Chinese Academy of Sciences in 2011 and was named a Fellow of the Royal Society of Chemistry in 2014, recognizing her leadership in green chemistry. The Cellulose and Renewable Materials Division of the American Chemical Society recognized her contributions to the science of polysaccharides with the 2011 Anselme Payen Award, making her the first Chinese scientist to win the award.
