News of the winning of the UMD Sustainability Fund by the GEMSTONE team BACTERIA, mentored by Prof. Das, has been published in UMD Mechanical Engineering Department’s webpage. Here is the link

GEMSTONE Team (Team BACTERIA) mentored by Dr. Siddhartha Das has won $5000 in the UMD Sustainability Fund competition for conducting research on bacterial enzyme driven breakdown of asphaltene for heavy oil recovery. Congratulations to the entire team.

Prof. Siddhartha Das delivers an invited talk at Harvard University on the topic “Liquid-Complex-Solid Interfaces”.

In this paper, the role of surface charge on soft wetting has been discussed for the first time. The work is based on a new theoretical model that allows to probe the asymmetric case when the solid-liquid surface energy is different from the solid-vapor surface energy. This is 1st paper of Jing from the group

This paper studies the impact of the ion-concentration-dependent configurational specificities of the end-charged polyelectrolyte (PE) brushes in the development of ionic current in nanochannels grafted with end-charged, pH-responsive PE brushes. This is Guang’s 12th paper in SMIEL. Many congratulations Guang !!!!

This paper probes the role of electric double layer in spreading dynamics of liquid drops on charged surfaces. This is the 9th paper of Shayandev and 11th paper of Guang from SMIEL. This paper also involves two undergraduates, Vineet and Eric, who have worked in SMIEL. Congratulations to all!!!!

This paper, written with Prof. Thundat and other members of University of Alberta, studies the interfacial dynamics of SAGD water.

Dr. Yuan Gu has started as a Postdoc in SMIEL from October 1, 2016. He is jointly advised by Prof. Das and Prof. Dasgupta and will be actively working in the LPS on the 3-D printed electronics. Yuan has completed his PhD in physics from New Jersey Institute of Technology.

In this paper, Dr. Das and his students collaborate with Prof. Bing Hu of Materials Science and Engineering, UMD to study the property of wood nanochannels as wood carbon monolith reactor.

SMIEL has received funding from CECD (Center for Engineering Concepts Development), UMD for the proposal “Probing Water–Holey-Graphene interactions for Removing Lead from Water and Oil-Water Separation”.
