The paper explains that low Reynolds number bacterial biofilm streamers form as highly viscous liquid jets – such a hypothesis can explain hitherto unexplained experimental findings related to bacterial biofilm streamers.

The paper proposes a theoretical model for the filling of a charged nanocapillary.

Dr. Siddhartha Das delivers a talk on “Role of Surface Charges in Drop-Evaporation-Triggered “Coffee-Stain” Formation” in Ninth International Conference on TWO-PHASE SYSTEMS FOR GROUND AND SPACE APPLICATIONS Baltimore, Maryland, USA, September 22-26, 2014.

Guang Chen (PhD candidate), Jahin Patwary (MS Candidate), Joseph Andrews (Undergraduate researcher) and Kyle McDaniel (Undergraduate researcher) have started working in SMIEL. Welcome on board !!!!!!!!!

The paper reports derivation of a new explicit interrelationship connecting the surface and the Donnan potentials of a charged soft interface. This paper is also Prof. Das’ 50th paper.

The paper reports multifold increase in electrochemomechanical energy conversion in soft nanochannels.

Two summer interns: Kyle McDaniel of Howard Community College and Fedra Valcius of Prince George’s Community College start working in SMIEL. They are working on Charging of Soft Interfaces.

Dr. Das has been awarded the Minta Martin funding for FY15 for working on modelling of evaporation-triggered nancomposite formation for aerospace applications

Paper titled “Drops on soft solids: free energy and double transition of contact angles” accepted in Journal of Fluid Mechanics. This is group’s 1st paper in this very prestigious journal. 

Dr. Siddhartha Das started as an Assistant Professor in the Department of Mechanical Engineering, University of Maryland, College Park from March 1, 2014.
