A dielectric barrier discharge reactor packed with both Hopcalite & glass beads has been investigated for the total oxidation of toluene adsorbed on Hopcalite. The catalytic activity and selectivity through possible formation by-products during NTP abatement irreversibly have by FT-IR mass spectrometer. regeneration used established (i) determining amount regenerated Hopcalite, (ii) investigati...

We report the results of 1D particle-in-cell simulations of ultrarelativistic shock waves in proton-electron-positron plasmas. We consider magnetized shock waves, in which the upstream medium carries a large scale magnetic field, directed transverse to the flow. Relativistic cyclotron instability of each species as the incoming particles encounter the increasing magnetic field within the shock ...

OBJECTIVE The purpose of this study was to reveal the effectiveness of non-thermal atmospheric plasma brush in surface wettability and modification of four dental substrates. METHODS Specimens of dental substrates including dentin, enamel, and two composites Filtek Z250, Filtek LS Silorane were prepared (∼2mm thick, ∼10mm diameter). The prepared surfaces were treated for 5-45s with a non-ther...

in this paper, thermal effect of plasma arc welding is investigated, and temperature field of ferrite stainless steel is acquired. thermal effect of plasma arc and subsequently the generated temperature field in the work piece is the key for analysis and optimization of this welding process, which is the main goal of this paper. finite element simulation of welding process by simplec method and...

Introduction A lot of research has been done in catalytic reforming of methane with carbon dioxide. However, the major drawback of the reaction is the cost of the process which requires temperatures between 800 and 1000°C. In these fields, significant advantages are currently expected from non traditional approaches to catalysis. One of these new approaches consists to perform the chemical acti...

Article history: Received 18 March 2016 Revised 16 July 2016 Accepted in revised form 28 July 2016 Available online xxxx Photoluminescence piezospectroscopy (PLPS) was used as a non-destructive technique for the measurement of residual stresses within the thermally grown oxide (TGO) layer beneath plasma-spray thermal barrier coatings (TBC). The technique has proved to be very effective for such...
