Model of Biomineralization of Ferrum Compounds by Gallionella Cells Immobilized on Contact Loading of Bioreactor

Energy Engineering and Control Systems, 2017
In the underground waters not polluted by organic compounds the bivalent iron occurs in the form of hydrocarbonates. An inseparable part of ferrum ions are ferrum bacteria.

Kinetic Modeling of Radiation Belt Electrons With Geant4 to Study Energetic Particle Precipitation in Earth's Atmosphere

Earth and Space Science, 2023
We present a new model designed to simulate the process of energetic particle precipitation, a vital coupling mechanism from Earth's magnetosphere to its atmosphere.

Quantum Theory of Scattering of Nonclassical Fields by Free Electrons

Mathematics, 2023
At present, there is no non-perturbative theory of scattering of nonclassical electromagnetic waves by free electrons that describes the scattering process completely with the help of quantum physics.

Effects of energetic electrons on the electrodynamics in the ionosphere [PDF]

, 2004
International audienceFrom the observations by the PIXIE and UVI cameras on board the Polar satellite, we derive global maps of the precipitating electron energy spectra from less than 1keV to 100keV.

Electron radiation belt dynamics during magnetic storms and in quiet time

Solar-Terrestrial Physics, 2018
The paper discusses the outer electron belt dynamics, adiabatic and nonadiabatic mechanisms of increases and losses of energetic electrons. Under undisturbed conditions, the outer electron belt gradually empties: in the inner magnetosphere due to ...

Electron-Driven Instabilities in the Solar Wind

Frontiers in Astronomy and Space Sciences, 2022
The electrons are an essential particle species in the solar wind. They often exhibit non-equilibrium features in their velocity distribution function.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

TEM sample preparation of lithographically patterned permalloy nanostructures on silicon nitride membranes

Beilstein Journal of Nanotechnology
We have prepared ferromagnetic nanostructures intended for the investigation of high-frequency magnetization dynamics in permalloy (Py) nanodisks using Lorentz transmission electron microscopy (LTEM) and electron holography.

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
