We report the spark discharge synthesis of aerosol germanium nanoparticles followed by sintering in a tube furnace at different temperatures varying from 25 to 800 °C. The size, structure, chemical composition and optical properties were studied. have demonstrated melting mechanism agglomerates, growth mean primary particle size 7 51 nm reduction agglomerates with temperature increase. According transmission electron microscopy (TEM) Fourier transform infrared (FTIR) data, sintered 475 °C...
A new approach to the high-yield synthesis of nanoparticles in multi-gap (up 12) spark discharge generator operating at a repetition rate as high 2.5 kHz is discussed. This allows increase production by factor up 100 compared conventional utilizing single gap self-breakdown mode. In case erosion aluminum electrodes air atmosphere, 300 mg/h has been achieved. From analysis transmission electron microscopy images it was found that primary particles synthesized material are nearly spherical...
Experiments on the 1-MA ZEBRA accelerator with reduced current prepulse duration, using a flashover switch, demonstrate significant increase of initial energy deposition into tungsten wire array before breakdown, and total radiation from Z pinch. Shorter raises rate through each individual in results an cores breakdown. In our experiments, inferred temperature increases ∼800K (with 250ns prepulse) up to ∼3700K 60ns prepulse). Total 12 16kJ. Our experimental relate wire-array initiation...
The particle-in-cell simulation is applied to study a nanometer-sized dielectric particle lofting from substrate exposed low-energy electron beam. article discusses the accumulation between and lying on it, which can cause lofting. results are of interest for dust mitigation in semiconductor industry, lunar exploration, explanation levitation.
Single-phase samples of the Sn2-2xSbxFexO4 solid solution were prepared by solid-state reaction in air at 1300 °C for 0.26 ≤ x 0.66. The crystal structure phases was studied electron diffraction and X-ray powder diffraction. compounds crystallize with rutile type a disordered arrangement cations (P42/mnm space group, = 4.7127(6) Å, c 3.1595(4) RI 0.020, RP 0.019 Sn1.48Sb0.26Fe0.26O4 4.6682(8) 3.1147(6) 0.030, 0.022 Sn0.68Sb0.66Fe0.66O4). valence state Sn0.68Sb0.66Fe0.66O4 determined means...
The production of airborne nanoparticles by multi gap spark discharge generators is shown to be feasible for semiconductors on the example erosion germanium and silicon electrodes in inert atmosphere. Pure crystalline with mean diameter less than 15 nm combined submicron agglomerates were obtained. Since presence residual oxygen setup partially oxidized core-shell structures pure Ge core shell also observed samples. This continuous technique enables direct impaction prepared onto a liquid or...
Presents experimental data obtained for the variation of specific volume liquid metals Al, Cu, Mo, Ta and W with applied energy produced by pulsed electric heating wires material. The was measured two methods; first is based on fact that electrical resistance wire free expansion differs from when limited a surrounding capillary tube, in second using contact between expanding fixed probes.
Cadmium meta- and orthostannate were synthesized by thermal treatment using the coprecipitation method. Tin (IV) chloride, cadmium acetate used as initial components, ammonium carbonate was a precipitant. The coprecipitated compounds thermolysis products analyzed TGA/DSC methods, samples studied XRD SEM. formation of proper in soft conditions confirmed. stannates terms submicron sized particles observed microscopial investigation.
