Development of Heat Engines Powered by Twisted and Coiled Polymer Fiber Actuators
Advanced Materials Technologies, EarlyView.Continuously rotating engines driven by thermally responsive actuating materials can turn waste heat into useful energy. For the first time heat engines operated by twisted and coiled polymer fiber actuators are demonstrated with engine design guided by two simple analytical models.

Advanced Materials Technologies, EarlyView.Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.

Metachronal Swimming With Rigid Arms Near Boundaries
Fluids, 2020 Various organisms such as crustaceans use their appendages for locomotion. If they are close to a confining boundary then viscous as opposed to inertial effects can play a central role in governing the dynamics.

Flow Features of Three Side-by-side Circular Cylinders at Low Reynolds Number
MATEC Web of Conferences, 2016 In order to study the fluctuation of kinetic parameter of cylinder matrix in incompressible stationary flow, the flow fluid around three side-by-side circular cylinders are simulated using Immersed Boundary–Lattice Boltzmann method (IB-LBM).

Low Reynolds Number Nozzle Flow Study [PDF]
An experimental study of low Reynolds number nozzle flow was performed. A brief comparison was made between some of the experimental performance data and performance predicted by a viscous flow code. The performance of 15, 20, and 25 deg conical nozzles,
