The role of magnetic energy on plasma localization during the glow discharge under reduced pressure

Nukleonika, 2016
In this work, we present the first results of our research on the synergy of fields, electric and magnetic, in the initiation and development of glow discharge under reduced pressure.

Two-dimensional simulation of an Ar/H2 direct-current discharge plasma

AIP Advances, 2021
We created a two-dimensional, mathematical fluid model of a plasma in a spherical direct-current (DC) glow-discharge chamber based on the finite-element method (FEM) using the commercial FEM solver COMSOL Multiphysics. The model is based on the Boltzmann

Comparative investigation on the characteristics of glow discharge plasma using glow discharge mass spectrometry and glow discharge optical emission spectrometry

Journal of Analytical Atomic Spectrometry, 2002
In glow discharge mass spectrometry (GDMS) and glow discharge optical emission spectrometry (GDOES), variations in the signal intensities against the discharge parameters: current, voltage and the pressure of plasma gas, are compared to clarify their excitation/ionization processes responsible to each signal.

A Study of the Features of Coating Deposition on a Carbide Substrate Using Preliminary Etching with Glow-Discharge Plasma

Surfaces
The properties of coatings obtained using two surface preparation methods were compared: heating and etching by ion bombardment with plasma generation by arc evaporators and heating and etching by a glow discharge.

Axial light emission and Ar metastable densities in a parallel plate dc micro discharge in steady state and transient regimes

, 2011
Axial emission profiles in a parallel plate dc micro discharge (feedgas: argon; discharge gap d=1mm; pressure p=10Torr) were studied by means of time resolved imaging with a fast ICCD camera.

Period doubling in glow discharges: local versus global differential conductivity [PDF]

, 2003
Short planar glow discharges coupled to a resistive layer exhibit a wealth of spontaneous spatio-temporal patterns. Several authors have suggested effective reaction-diffusion-models to explore similarities with other pattern forming systems.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...
