Experimental and theoretical study of charge transfer in hydrogen ion scattering from a graphite surface
(Elsevier Science, 2007-12)
Ion scattering spectrometry (ISS) with time of flight (TOF) analysis is employed to measure the ion fraction of positively charged hydrogen (H+) projectiles scattered from a well characterized highly oriented pyrolitc ...
Adsorption of dihydrogen phosphate ion on platinum electrodes in aqueous media monitored by probe-beam deflection
(2005-06-07)
Probe-beam deflection (PBD) was used to monitor concentration gradients of anions adjacent to the surface of a platinum electrode in acidic aqueous media containing H3PO4. PBD can measure the potential-dependent extent of ...

Gold ion implantation into alumina using an “inverted ion source” configuration.
(AIP PublishingAIP Publishing LLCNova York, 2014-02-21)
We describe an approach to ion implantation in which the plasma and its electronics are held at
ground potential and the ion beam is injected into a space held at high negative potential, allowing
considerable savings ...
Influence of negative ions on the humidity effect on the first corona inception
(Inst. of Phys. Publ. Ltd., 2007-12)
The first corona inception in a divergent electric field is affected by atmospheric parameters. The effect of humidity is a little-debated question and a summary review is first proposed in this paper. Then we present ...
Recoil-ion fractions in collisions of keV Ar+ and Kr+ ions with clean and adsorbate covered GaAs(1 1 0) surfaces
(Elsevier Science, 2002-12)
Ion scattering and recoiling spectroscopy with time of flight analysis is used to study the ion fractions of Ga and As atoms recoiled in collisions of 5 keV Ar+ and Kr+ with clean GaAs(1 1 0) and with GaAs(1 1 0) covered ...
Compatibility of Aprotic Electrolytes with Negative Electrode Materials in Lithium-ion Batteries
(Electrochemical Society, 2014-10)
This short research presents an introduction to the fire safety of Lithium-ion batteries. Nowadays, as the most weak part of aprotic battery is its aprotic electrolyte. The aprotic electrolyte (commonly the mixture of ...
In situ-formed nitrogen-doped carbon/silicon-based materials as negative electrodes for lithium-ion batteries
(2021-11-15)
The development of negative electrode materials with better performance than those currently used in Li-ion technology has been a major focus of recent battery research. Here, we report the synthesis and electrochemical ...
Caracterização morfológica da corrosão por pite da liga AL2024 em soluções contendo cloretos e molibdatos
(2003-12-01)
A very new method application for digital image processing and analysis to classify shape and evaluate size and morphology parameters of pit corrosion is used in this paper. This method seems to be very effective to analysis ...
