The structural relaxation time of a polymer glass during deformation
Pradip K. Bera, Grigori A. Medvedev, James M. Caruthers +1
In order to determine the structural relaxation time of a polymer glass during deformation, a strain rate switching experiment is performed in the steady-state plastic flow regime.…
Shape-Independent Fluidity in Epithelial Cell Monolayers
Pradip K. Bera, Anh Q. Nguyen, Molly McCord +2
Tissue fluidity regulates biological processes such as embryonic development, wound healing, and cancer metastasis. In confluent epithelia, where cell packing fraction is effective…
Cell-Cell Adhesion as a Double-Edged Sword in Tissue Fluidity
Anh Q. Nguyen, Pradip K. Bera, Jacob Notbohm +1
Cell migration plays a fundamental role in numerous physiological processes, including embryonic development, wound healing, and cancer metastasis. While cell-cell adhesion is know…
Instability and stress fluctuations of a probe driven through a worm-like micellar fluid
Abhishek Ghadai, Pradip Kumar Bera, Sayantan Majumdar
A particle moving through a worm-like micellar fluid (WLM) shows instability and large fluctuations beyond a threshold \textcolor{black}{velocity/force (depending on the control pa…
Traction and Stress Control Formation and Motion of +1/2 Topological Defects in Epithelial Cell Monolayers
Pradip K. Bera, Molly McCord, Jun Zhang +1
In confluent cell monolayers, patterns of cell forces and motion are systematically altered near topological defects in cell shape. In turn, defects have been proposed to alter cel…
Shear-induced ordering of nano-pores and instabilities in concentrated surfactant mesh phases
Pradip K. Bera, Vikram Rathee, Rema Krishnaswamy +1
Mixed surfactant systems with strongly bound counterions show many interesting phases such as the random mesh phase consisting of a disordered array of defects (water-filled nano-p…
Motile dissenters disrupt the flocking of active granular matter
Pradip K. Bera, A. K. Sood
We report flocking in the dry active granular matter of millimeter-sized two-step-tapered rods without an intervening medium. The system undergoes the flocking phase transition at…
Grazing incidence x-ray diffraction studies of lipid-peptide mixed monolayers during shear flow
Pradip Kumar Bera, Ajoy Kumar Kandar, Rema Krishnaswamy +7
Grazing Incidence X-ray Diffraction (GIXD) studies of monolayers of biomolecules at the air-water interface give quantitative information of in-plane packing, coherence lengths of…
