ChBE alumnus Dr. Animangsu Ghatak publishes a paper in Proceedings of the National Academy of Sciences

Dr. Animangsu Ghatak, a graduate from the department (PhD, 2003), recently published a paper entitled "Estimation of solid–liquid interfacial tension using curved surface of a soft solid" with co-authors S. Mondala and M. Phukana in a recent issue of Proceedings of the National Academy of Sciences (PNAS). The paper reports a new method of estimating surface tension of a soft elastomeric solid in contact with a liquid and shows that unlike many crystalline solids, for amorphous solids like elastomers, surface tension and surface energy values are similar.

PNAS, the principle journal of the National Academy of Sciences, is one of the world's most-cited and comprehensive multidisciplinary scientific journals, publishing more than 3,800 research papers annually. Established in 1914, PNAS publishes cutting-edge research, science news, Commentaries, Reviews, Perspectives, Colloquium Papers, and actions of the National Academy of Sciences. Dr. Ghatak received his PhD in Chemical Engineering at Lehigh in 2003 under the supervision of Professor Manoj Chaudhury. Subsequently, he pursued a postdoctoral position at Cambridge University, UK and Harvard University, USA studying instability and fracture of soft materials.

He joined the Department of Chemical Engineering at the Indian Institute of Technology, Kanpur in 2004 as an Assistant Professor and was promoted to Associate Professor in 2009. Dr. Ghatak has received the Young Engineer Award of the Indian National Academy of Engineering in 2006, Humboldt Research Fellowship in 2010, and has published in Science, Advanced Materials, Physical Review Letters, Proc. National Academy of Sciences, Langmuir and Soft Matter. In 2014, Dr. Ghatak was named a Gireesh Jankinath Chair Professor in Chemical Engineering at the Indian Institute of Technology, Kanpur. His research interests are in the areas of Adhesion, friction and fracture at soft interfaces, locomotion of soft objects, flow through microfluidic channels.
