Polypropylene (PP) powders are coated with silica nanoparticles in a fluidized bed to improve the flow behavior of and processability powder fusion. The produced situ via dusty plasma-enhanced chemical vapor deposition (PECVD) an atmospheric-pressure Ar/O2 plasma jet fixed at distributor plate bed. Hexamethyldisiloxane is used as precursor nanoparticles. influence oxygen concentration gas numbe...

lithum can be de termined both by atomic absorption spectroscopy andflame emission spectroscopy. we have used the later method with a zeiss model pmqli spectro photometer fitt ed with ante-chamber atomizer and a potensiome rric line recorder. accurate ana lysis for the clement was acco mplished due to a sophisracared measuring instrument.

Abstract In a dusty plasma, nanometer-sized solid dust particles can be grown by the polymerization of plasma species from reactive precursor gas. This type found in large-scale astrophysical objects, as well semiconductor manufacturing and material processing. laboratory environment, parameters carefully controlled dynamics growth interaction between studied. this work, we investigate cyclic l...

Abstract Detachment, an important mechanism for reducing target heat deposition, is achieved through reductions in power, particle and momentum; which are induced plasma–atom plasma–molecule interactions. Experimental research how those reactions precisely contribute to detachment limited. Both as well interactions can result excited hydrogen atoms emit atomic line emission. In this work, we in...

The influence of a bio-decontaminating atmospheric pressure plasma (1.1 MHz, Ar/O2), on the physicochemical surface properties of medical polymers is investigated. The plasma exposure results in the incorporation of oxygen which, in turn, leads to the formation of oxygen-containing groups and in changes in surface roughnesses. Furthermore, it is observed that the modification of the polymers oc...

The concentrations of five essential elements and six potentially toxic elements were determined in seven organs collected at autopsy from 30 human subjects. Elemental analyses were carried out by graphite furnace atomic absorption spectroscopy, and inductively coupled plasma emission spectroscopy, and inductively coupled plasma mass spectroscopy, and concentrations in fresh and formalin-fixed ...

Planar slabs of pure Li were irradiated with 1.064 nm, 6 ns Nd:YAG laser pulses. Determination of plasma densities at both the earliest times of plasma formation and near the target surface was performed using Nomarski interferometry. The plasma parameters at later times were evaluated using optical emission spectroscopy. The space- and time-dependent electron densities and temperatures of the ...

Previously published applications of optical emission spectroscopy as a quantitative plasma diagnostic technique are reviewed. By adding traces of rare gases to the plasma, electron temperatures (Te) and relative electron and ion densities can be determined from electron impact-induced optical emission. Excitation from both the ground state and metastable states of the rare gases must be consid...

The system based on spatially resolved optical emission spectroscopy dedicated for in situ diagnostics of plasma assisted CVD processes is presented in this paper. Measurement system coupled with chemical vapour deposition chamber by dedicated fiber-optic paths enables investigation of spatial distribution of species densities (Hx, H , CH, CH) during chemical vapour deposition process. Experime...

The interaction of a sub-picosecond (sub-ps) laser with a high-Z target produces a hard x-ray continuum, but to our knowledge no high-resolution study of the line emission is known. We present here crystal spectroscopy as a tool for the observation of energetic line x-radiation from a sub-ps laser-produced plasma. Reflection properties of flat and bent crystals for x-ray spectroscopy are analyz...
