Prof. Das hoods SMIEL’s first PhD Dr. Guang Chen. Here is the picture

In this paper, we develop a scaling theory and perform MD simulations to describe the equilibrium of polymer brushes in weak interpenetration regime. This is Parth’s first paper and Shayandev’s 13th paper from the group. More importantly, this is group’s first paper in MD simulations of polymer brushes….congrats!!!

In this paper, we use MD simulations to establish that drops spread on superhydrophobic surfaces by the bending of the air-liquid interface. This is Yanbin’s first first-authored paper and second paper from the group. This is also Joseph’s 3rd paper from the group.

GEMSTONE Team BACTERIA, mentored by Dr. Das, wins the Best Poster award for the GEMSTONE Junior Year Poster presentation. Here is the poster.

In this paper, we employ MD simulations to discover a new mechanism for fabricating superhydrophobic graphene by using wetting-translucency property of graphene. This is Joseph’s 2nd, Shayandev’s 12th, and Yanbin’s 1st paper from the group. Congrats to all three !!!

SMIEL M.S. student Joseph Andrews wins the Best M.S thesis award of the Department of Mechanical Engineering, UMD for the year 2016….heartiest congratulations, Joseph…what an achievement….SMIEL family is very proud of you….

This work is with Prof. Bing Hu’s group and it develops a wood membrane for efficient water purification. The contribution of our group was simulating the process. Guang led the simulations efforts. This is Guang’s 14th paper from the group….

The paper demonstrates the origin of charge-inversion-like electrostatics for charged semi-permeable membranes. This is Shayandev’s 11th paper and Jing’s 2nd paper from the group. Congrats to both !!!!!

The paper proposes to graft nanochannels with end-charged polyelectrolyte brushes for ensuring a massive enhancement of electroosmotic transport — the work reverses the idea that brush-grafted nanochannels will necessarily demonstrate a weaker transport. This is Guang’s 13th paper in SMIEL. Huh…Congrats….
