Low-frequency, high-density, inductively coupled plasma sources: operation and applications [PDF]

, 2001
Operation regimes, plasma parameters, and applications of the low-frequency ( - 500 kHz) inductively coupled plasma (ICP) sources with a planar external coil are investigated. It is shown that highly uniform, high-density (ne -9×1012 cm−3) plasmas can be

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

Advanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Multi-element analysis of Macedonian wines by inductively coupled plasma–mass spectrometry (ICP–MS) and inductively coupled plasma–optical emission spectrometry (IP–OES) for regional classification

Macedonian Journal of Chemistry and Chemical Engineering, 2013
Major, minor, and trace elements in wines from the Republic of Macedonia were determined in this study. Both inductively coupled plasma–mass spectrometry (ICP-MS) and inductively coupled plasma– optical emission spectrometry (ICP-OES) were used for ...

Deposition of transparent conducting Al-doped ZnO thin films by ICP-assisted sputtering [PDF]

, 2010
Aluminum-doped zinc oxide (AZO) is one of the promising transparent conductive oxide materials, which is expected to be an alternative to tin-doped indium oxide (ITO) that for long has been widely used in industry.

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx

Advanced Materials, EarlyView.
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

Phase Boundary Engineering of Co2P‐CoP Branched Nanoparticles Enhances Cobalt Oxidation for Oxygen Evolution Electrocatalysis

Advanced Materials, EarlyView.
Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and

PROBLEMS OF IODIDE IONS DETERMINATION IN MULTIVITAMINS BY INDUCTIVELY COUPLED PLASMA ATOMIC-EMISSION SPECTROMETRY

Регуляторные исследования и экспертиза лекарственных средств, 2018
The article looks into the main problems of determination of iodine trace amounts in multivitamins by inductively coupled plasma-atomic emission spectrometry (ICP-AES), i.e. spectral overlaps attributable to macro-components, and the background effect of
