Statistical mechanics of two-dimensional Euler flows and minimum enstrophy states

, 2010
A simplified thermodynamic approach of the incompressible 2D Euler equation is considered based on the conservation of energy, circulation and microscopic enstrophy.

Simulations of a weakly conducting droplet under the influence of an alternating electric field

, 2020
We investigate the electrohydrodynamics of an initially spherical droplet under the influence of an external alternating electric field by conducting axisymmetric numerical simulations using a charge-conservative volume-of-fluid based finite volume flow ...

Starting flow through nozzles with temporally variable exit diameter [PDF]

, 2005
Starting flow through a nozzle or orifice typically results in the transient formation of a leading vortex ring and trailing jet. Experiments are conducted to investigate the dynamics of this process in the case of a temporally variable nozzle exit ...

Effects of Surfactant Solubility on the Hydrodynamics of a Viscous Drop in a DC Electric Field

, 2020
The physico-chemistry of surfactants (amphiphilic surface active agents) is often used to control the dynamics of viscous drops and bubbles. Surfactant sorption kinetics has been shown to play a critical role in the deformation of drops in extensional ...

Earthing effects on mitochondrial function: ATP production and ROS generation

FEBS Open Bio, EarlyView.
In contrast to sham and naive controls, grounded mitochondria not only exhibit significantly enhanced energy production but also demonstrate a remarkable reduction in membrane potential and oxidative stress. This suggests a profound improvement in mitochondrial health, presenting a promising avenue for therapeutic interventions.

The physical oceanography of the transport of floating marine debris

Environmental Research Letters, 2020
Marine plastic debris floating on the ocean surface is a major environmental problem. However, its distribution in the ocean is poorly mapped, and most of the plastic waste estimated to have entered the ocean from land is unaccounted for.

An efficient strategy for producing RNA‐free Nucleocapsid protein of SARS‐CoV‐2 for biochemical and structural investigations

FEBS Open Bio, EarlyView.
Cleavable N‐terminal Thioredoxin fusion enabled soluble expression and purification of otherwise insoluble SARS‐CoV‐2 Nucleocapsid (N) protein. A four‐step purification strategy yielded highly homogeneous, RNA‐free N protein. Binding assays showed high RNA affinity (Kd ~ 28 nm). The study will facilitate high‐resolution structural studies of N protein,
