Energy spectra of vortex distributions in two-dimensional quantum turbulence

, 2012
We theoretically explore key concepts of two-dimensional turbulence in a homogeneous compressible superfluid described by a dissipative two-dimensional Gross-Pitaeveskii equation. Such a fluid supports quantized vortices that have a size characterized by

Sharp commutator estimates of all order for Coulomb and Riesz modulated energies

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We prove functional inequalities in any dimension controlling the iterated derivatives along a transport of the Coulomb or super‐Coulomb Riesz modulated energy in terms of the modulated energy itself. This modulated energy was introduced by the second author and collaborators in the study of mean‐field limits and statistical mechanics of ...

Wave-turbulence decomposition and turbulence parameterization in aquatic wave environments using improved Synchrosqueezed Wavelet Transform (iSWT)

Ecological Informatics
Accurate quantification of near-surface turbulence is essential for understanding the dynamics of turbulent mixing and mass transport in aquatic systems. However, field measurements of near-surface flow velocities often include contributions from surface

Lanthanide Sulfate Recovery by Synergistic Dimethyl Ether and Na2SO4 Fractional Crystallization

ChemSusChem, EarlyView.
This work demonstrates synergistic lanthanide salt recovery from an aqueous magnet leachate to single ppm concentrations using Na2SO4 combined with dimethyl ether crystallization. This waste valorization process minimizes chemicals consumed and waste generated while maximizing the recovery of a critical material product. Lanthanides (Lns) are important

Electron-scale reduced fluid models with gyroviscous effects

, 2017
Reduced fluid models for collisionless plasmas including electron inertia and finite Larmor radius corrections are derived for scales ranging from the ion to the electron gyroradii.

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

Contributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

On dissipation timescales of the basic second-order moments: the effect on the energy and flux budget (EFB) turbulence closure for stably stratified turbulence [PDF]

Nonlinear Processes in Geophysics
The dissipation rates of the basic second-order moments are the key parameters playing a vital role in turbulence modelling and controlling turbulence energetics and spectra and turbulent fluxes of momentum and heat.

Investigation of formation mechanism of tufa deposits by chemical breakdown of legacy paper mill sludge

The Depositional Record, EarlyView.
This study reveals that legacy paper mill sludge can generate tufa deposits through calcium leaching and atmospheric CO2 interaction, acting as a carbon sink. The findings highlight its potential for low‐cost carbon sequestration and sustainable waste management.

Scaling Transition of Active Turbulence from Two to Three Dimensions

Advanced Science
Turbulent flows are observed in low‐Reynolds active fluids, which display similar phenomenology to the classical inertial turbulence but are of a different nature.
