Confinement and activity regulate bacterial motion in porous media
Tapomoy Bhattacharjee, Sujit S. Datta
Understanding how bacteria move in porous media is critical to applications in healthcare, agriculture, environmental remediation, and chemical sensing. Recent work has demonstrate…
Scaling Law for Cracking in Shrinkable Granular Packings
H. Jeremy Cho, Sujit S. Datta
Hydrated granular packings often crack into discrete clusters of grains when dried. Despite its ubiquity, accurate prediction of cracking remains elusive. Here, we elucidate the pr…
Pore-Scale Flow Characterization of Polymer Solutions in Microfluidic Porous Media
Christopher A. Browne, Audrey Shih, Sujit S. Datta
Polymer solutions are frequently used in enhanced oil recovery and groundwater remediation to improve the recovery of trapped non-aqueous fluids. However, applications are limited…
Controlling capillary fingering using pore size gradients in disordered media
Nancy B. Lu, Christopher A. Browne, Daniel B. Amchin +2
Capillary fingering is a displacement process that can occur when a non-wetting fluid displaces a wetting fluid from a homogeneous disordered porous medium. Here, we investigate ho…
Crack formation and self-closing in shrinkable, granular packings
H. Jeremy Cho, Nancy B. Lu, Michael P. Howard +2
Many clays, soils, biological tissues, foods, and coatings are shrinkable, granular materials: they are composed of packed, hydrated grains that shrink when dried. In many cases, t…
Bacterial hopping and trapping in porous media
Tapomoy Bhattacharjee, Sujit S. Datta
Diverse processes--e.g. bioremediation, biofertilization, and microbial drug delivery--rely on bacterial migration in disordered, three-dimensional (3D) porous media. However, how…
