In this paper we provide a new integro-differential model to calculate the streaming potential and electroviscous effects in soft nanochannels beyond Debye-Hückel linearization. This is Guang’s second paper….Many congratulations Guang……

In this paper a novel Electron Force Microscopy based technique for measuring asphaltene native surface charge in air is proposed

News on Scientific Reports paper on Biofilm Streamers has been published in the front page of the website of the Department of  Mechanical Engineering, University of Maryland. Here is the link: http://www.enme.umd.edu/news/news_story.php?id=8709

The paper provides the hitherto unknown electrostatics in PEL-grafted nanochannels with explicit consideration of hydrogen ion concentration. This is the first paper of Guang….Congratulations Guang!!!!!!!!!!!!

Dr. Siddhartha Das delivers a lecture on “Soft Matter: Fundamentals and Applications” to the 1st year engineering students at the Howard Community College

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.
