Optimizing the Accuracy of Viscoelastic Characterization with AFM Force-Distance Experiments in the Time and Frequency Domains
Marshall R. McCraw, Berkin Uluutku, Halen D. Solomon +3
We demonstrate that the method of characterizing viscoelastic materials with Atomic Force Microscopy (AFM) by fitting analytical models to force-distance (FD) curves often yields c…
Shear induced collective diffusivity in an emulsion of viscous drops using dynamic structure factor: effects of viscosity ratio
Abhilash Reddy Malipeddi, Kausik Sarkar
The shear induced collective diffusivity in an emulsion of viscous drops, specifically as a function of viscosity ratio, was numerically computed. An initially randomly packed laye…
The dynamic of contrast agent and surrounding fluid in the vicinity of a wall for sonoporation
Nima Mobadersany, Kausik Sarkar
Contrast microbubbles (contrast agents) were initially developed to increase the contrast of the image in ultrasound imaging. These microbubbles consist of a gas core encapsulated…
Acoustic microstreaming near a plane wall due to a pulsating free/coated bubble: Nyborg result revisited and vortices
Nima Mobadersany, Kausik Sarkar
Acoustic microstreaming due to an oscillating microbubble is analytically investigated to obtain the circular streaming motion adjacent to a nearby wall. Classical theory due to Ny…
Effects of ambient pressure on the subharmonic response from encapsulated microbubbles
Nima Mobadersany, Amit Katiyar, Kausik Sarkar
Subharmonic response from contrast microbubbles as a function of ambient overpressure is numerically investigated for subharmonic aided noninvasive estimation of local organ level…
Spatial ordering due to hydrodynamic interactions between a pair of colliding drops in a confined shear
Kausik Sarkar, Rajesh Kumar Singh
Pair-collision between viscous drops in a confined shear is numerically simulated to show that the confinement drastically alters the trajectories of the drops. In contrast to free…
