This work examines the properties of a dielectric barrier discharge (DBD) reactor, built for CO2 decomposition, by means electrical characterization, optical emission spectroscopy and gas chromatography. The discharge, formed in an electronegative (such as CO2, but also O2), exhibits clearly different characteristics, depending on surface conductivity reactor walls. An asymmetric current waveform is observed metal-dielectric (MD) configuration, with sparse high-current pulses positive...
Dielectric Barrier Discharges operating in CO and CO2 form solid products at atmospheric pressure. The main differences between both plasmas their deposits were analyzed, similar energy input. GC measurements revealed a mixture of CO2, CO, O2 the DBD exhaust, while no was found plasma. A coating nanoparticles composed Fe, O, C produced by discharge, whereas, microscopic dendrite-like carbon structure formed Fe3O4 Fe crystalline phases sample. deposition characterized as an amorphous...
O2 and CO2 Dielectric Barrier Discharges (DBD) were studied at elevated (i.e., above atmospheric) pressure regimes (1–3.5 bar). It was demonstrated that these operational conditions significantly influence both the discharge dynamics process efficiencies of discharges. For case DBD, rise results in amplification current, appearance emission lines metal electrode material (Fe, Cr, Ni) optical spectrum formation a granular film erosion products (10–300 nm iron oxide nanoparticles) on reactor...
Introduction. Ensuring reliable operation of hydraulic structures is inextricably linked with ensuring the strength and durability their structures. Hydraulic are characterized by long service life, therefore basis for In modern implementation a concrete project, there several methods increasing density, moisture resistance concrete, incl. use plasticizing additives. Aim. The study fluidity cement paste modified chemical plasticizer Materials methods. Portland CEM I 42.5N type was used as...
Calculations of maximum temperature difference and coefficient performance double segment Peltier thermocouple are presented. Distinction thermoelectric properties p- n-type segments is taken into account. Obtained results compared with measured characteristics manufactured thermocouples. It shown that efficiency thermocouples using distributed effect can be improved if optimized depending on used.
For various 3D integration schemes, such as Collective Die to wafer stacking (CoD2W) and (D2W) bonding, the thermal budget needs be well below 250°C due presence of temporary bonding materials. In this paper we, present a new PECVD SiCN layer deposited at 175°C, optimized for hybrid applications. The provides void-free interface demonstrated by high bond strength even post annealing (PBA) temperature 200°C devoid any outgassing voids until 350°C. Additionally, it has been verified that...
The coating plant for the M1 primary mirror segments of Extremely Large Telescope (ELT) currently under construction in Cerro Armazones, Chile by European Southern Observatory (ESO) will deposit a highly reflective protected-silver-based magnetron sputtering technology. This paper describes how AGC Glass Europe SA, through its business unit Plasma Technology Solutions, realized design and manufacture automated coater based on experience building large area architectural glass coaters.

Application of thermoelectric materials in devices requires creation commutational and antidiffusion coatings. Multilayer coatings on the surface elements Bi/sub 2/(Te/sub 1-x/Se/sub x/)/sub 3/ (Bi/sub 0.25/Sb/sub 0.75/)/sub 1-y/Se/sub y/)/sub were made by electron beam evaporation Mo, Ni Bi-Sn alloys vacuum. Dependence morphology upon substance summary thickness within range 0.5-10 /spl mu/m was investigated. It shown that solders with melting point up to 200/spl deg/C based can be applied...
The object of research is the soil model cave site, which approximates part underground structure Kyiv Pechersk Lavra (Kyiv, Ukraine). Long-term operation historical buildings in cramped conditions at 100% humidity and under influence aggressive influences internal external factors leads to exhaustion their structural reliability. When restoring objects, it advisable combine residual resources together with local reinforcements. Thanks this concept, original state restored, structures can...
