Spectrochemical Analysis of Boron in High Purity Silicate by DC Arc Discharge under Argon Atmosphere

Preparation of carbon nanotubes by DC arc discharge process under reduced pressure in an air atmosphere

Carbon nanotubes (CNTs) were grown using a DC arc discharge process in an air atmosphere and relevant process parameters were investigated. ithout using an inert gas, multi walled carbon nanotubes could be synthesized in the deposit area of the cathode even in an air atmosphere, but ingle walled carbon nanotubes were not detected in the soot area despite using the same process conditions as in ...

Macroparticle generation in DC arc discharge from a WC cathode

We have studied macroparticle generation from a tungsten carbide (WC) cathode used in a dc vacuum arc discharge. Despite a relatively high decomposition/melting point (~ 3100 K), there is an intensive generation of visible particles with sizes in the range 20-35 μm. Visual observations during the discharge and scanning electron microscopy of the cathode surface as well as of collected macropart...

Effect of arc behaviour on the temperature fluctuation of carbon electrode in DC arc discharge

Microanalysis of single-phase A1N nanocrystals and A1N-A1 nanocomposites prepared by DC arc-discharge

A1N nanocrystals and A1N-AI nanocomposites of < 100 nm size were prepared by the direct current (DC) arcdischarge plasma evaporation of aluminum in an ambient of N2 + NH3. The analysis of these two kinds of nanoparticles revealed that the AIN nanocrystals were single phase and single crystal. TheVAIN-A1 nanocomposites were composed of A1N single-crystals embedded in amorphous aluminum phase. Th...

Synthesis and electrochemical properties of silicon nanosheets by DC arc discharge for lithium-ion batteries.

Two-dimensional (2D) ultrathin silicon nanosheets (Si NSs) were synthesized by DC arc discharge method and investigated as anode material for Li-ion batteries. The 2D ultrathin characteristics of Si NSs is confirmed by means of transmission electron microscopy (TEM) and atomic force microscopy (AFM). The average size of Si NSs is about 20 nm, with thickness less than 2.5 nm. The characteristic ...
