Electron detachment from atomic negative ions

, 2004
This paper presents an introductory overview of various aspects of electron detachment from negative ions with emphasis on recent data. A brief discussion about negative ions and their states is presented followed by a discussion on photodetachment ...

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

FEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

Slow decay of temporary negative ions formed by low-energy electron attachment to fluoronitrobenzenes in the gas-phase.

, 2005
Low-energy (0-9 eV) electron capture by molecules of ortho- meta- and para-fluoronitrobenzenes has been investigated by means of electron attachment spectroscopy.

Misjudging negative ions for electrons in intense laser plasma diagnostics

AIP Advances, 2019
Intense laser produced plasmas are known to be novel compact sources of high energy electrons. Electrons deflected by magnetic fields and imaged on phosphorescent plates is a well used diagnostic for electron spectrum measurements.

INFLUENCE OF THE SIZE OF TOURMALINE PARTICLES APPLIED ON POLYESTER FABRIC ON THE RELEASE OF NEGATIVE IONS [PDF]

Annals of the University of Oradea: Fascicle of Textiles, Leatherwork, 2020
There are some scientific papers that verify that the generation of negative ions in the air have positive consequences on people’s mood and health. In this work is intended to increase the generation of negative ions from polyester fabrics to achieve ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Effect of Argon Additive in Negative Hydrogen Ion Sources

, 2001
We investigated using the photodetachment technique the negative ion density in the extraction region of a magnetically filtered multicusp ion source (21cm in diameter and 27 cm long) when argon is added to hydrogen (up to 100%).
