Hangjian Ling’s Research Website

James Bonnell and John Ready, two undergraduate students in FITs Lab, won the 2024 Fall OUR award from Office of Undergraduate Research. Congratulations!

Check out of our new publication in Physics of Fluids on the topic of bubble formation on superhydrophobic surface. We performed a focus balance analysis to understand the dynamics of bubble formation.

Shabnam passed her PhD thesis defense and will soon join New Mexico State University as an assistant professor. Daniel passed his MS thesis defense and will soon join NUWC. Farewell!

The FITs lab successfully hosted a one-week summer workshop for 8 high school students on a topic of “Fundamental, fabrication, application, and challenges of superhydrophobic surface“. The students learned various aspects of superhydrophobic material through various lab activities and hands-on experiments. This workshop was supported by NSF and Massachusetts Life Science Center program. Special thank you to our lab members (Ankit, Daniel, Shabnam, Dillon, and Isaac) who hosted the lab activities.

The FITs Lab welcome Foram S Fanasia to join as a new master student. Foram will work on a project on the stability of super-hydrophobic surface in turbulent flows.

Shabnam Mohammadshahi, a PhD candidate in Ling Lab, recently accepted an assistant professor position in the Department of Mechanical and Aerospace Engineering at New Mexico State University. Here is a news at UMassD website: https://www.umassd.edu/news/2024/phd-career-outcomes.html.

Dillon Singh and Isaac Rodriguez are supported by NSF REU site program leaded by Dr. Vijay Chalivendra. They will perform a 10-weeks research and will work on bubble dynamics on super-hydrophobic surfaces.

Super-hydrophobic surface (SHS), which traps micro/nano-scale gas bubbles on solid walls, has been reported to greatly reduce bacterial adhesion and biofouling. However, it is unclear whether and how the trapped gas bubbles reduce the bacterial adhesion. In this work, we examined the role of the trapped gas on the bacterial adhesion by measuring the spatial distributions of attached bacteria on SHS using scanning electron microscopy. Full article is available here.

This work is funded by UMass Dartmouth’s Marine and Undersea Technology (MUST) Research Program funded by the Office of Naval Research (ONR) under Grant No. N00014-20-1-2170.

Shabnam and Daniel’s paper entitled: “Impact of sandpaper grit size on drag reduction and plastron stability of super-hydrophobic surface in turbulent flows“ was published in Physics of Fluids. This work was supported by NSF and ONR.

James Bonnell and Shane Mercuri are undergraduate students at Mechanical Engineering. They will perform undergraduate research work in Ling’s Lab. Welcome!
