TL;DR: Zero-thickness interface models are developed to describe the encapsulation of microbubble contrast agents with rheological parameters such as surface tension, surface Dilatational viscosity, and surface dilatational elasticity to characterize a widely used microbubbles based ultrasound contrast agent.

TL;DR: A new model for contrast agents is developed, fitted in the linear regime, and successfully investigated its applicability for a wide range of operating parameters, showing that it can be used for characterizing different agents and designing new ones.

TL;DR: The nonlinear strain softening included in the proposed elastic models of the encapsulation improves their ability to predict subharmonic response, and they predict the threshold excitation for the initiation of sub Harmonic response and its subsequent saturation.

TL;DR: In this article, a new duct is developed for a given turbine design, that reduces the variation in torque over a cycle by appropriately directing the flow upstream and downstream the turbine while increasing power conversion.

TL;DR: In this paper, the authors investigated the characteristics of hydrogen bubble formation and its transport near the electrode surface during electrolysis of water and observed that the mean size of the bubble and its distribution near the cathode continuously changes over a period of an hour before reaching a steady state, particularly for high superficial current density.
