Combustion synthesis, characteriza.ion and luminescence properties of ba.ium aluminate phosphor

Journal of Rare Earths 2014年第9期32卷 806-811页

作者： A.h. Wako F.B Dejene h.C Swart Department of Physics University of the Free State (Qwaqwa Campus) Department of Physics University of the Free State

The blue-green emitting Eu2＋ and Nd3＋ doped polycrystalline ba.ium aluminate （Ba.i204：Eu2＋,Nd3＋） phosphor, was prepared by a solution-combustion method at 500 ℃without a post-annea.ing process. The characteristic va.ia.ion in the structural and luminescence properties of the as-prepared samples was evaluated with regards to a change in the ba/A1 molar ra.io from 0.1：1 to 1.4：1. The morphologies and the phase structures of the products were characterized by scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, X-ray diffraction （XRD） and X-ray photoelectron spectroscopy （XPS）, while the optical properties were investigated using ultra-violet （UV） and photoluminescence （PL） spectroscopy, respectively. The XRD and TEM results revealed that the average crystallite size of the baAl2O4：Eu2＋,Nd3＋ phosphor was about 70 urn. The broad-band UV-excited luminescence of the phosphors was observed at 2max=500 um due to transitions from the 4f^65d1 to the 4f7 configura.ion of the Eu2＋ ion. The PL results indicated that the main peaks in the emission and excita.ion spectrum of phosphor particles slightly shifted to the short wavelength due to the changes in the crystal field due to the structure changes caused by the va.ia.ion in the quantity of the Ba.ions in the host lattice.

A hierarchical metal-free catalyst consisting of nitrogen-doped carbon nanotubes decorated onto a silicon carbide (N-CNTs/SiC) macroscopic host structure was prepared. The influence of N-CNTs incorpora.ion on the physical properties of the support was evaluated using different characteriza.ion techniques. The catalyst was tested as a metal-free catalyst in the selective oxida.ion of h2S and steam-free dehydrogena.ion of ethylbenzene. The N-CNTs/SiC catalyst exhibited extremely good desulfuriza.ion performance compared to a Fe2O3/SiC catalyst under less conducive reaction conditions such as low temperature, high space velocity, and a low O2-to-h2S molar ra.io. For the dehy-drogena.ion of ethylbenzene, a higher dehydrogena.ion activity was obtained with the N-CNTs/SiC catalyst compared to a commercial K-Fe/Al2O3 catalyst. The N-CNTs/SiC catalyst also displayed good sta.ility as a function of time on stream for both reactions, which was attributed to the strong anchoring of the nitrogen dopant in the carbon matrix. The extrudate shape of the SiC support allowed the direct macroscopic sha.ing of the catalyst for use in a conventional fixed-bed reactor without the problems of catalyst handling, transporta.ion, and pressure drop across the catalyst bed that are encountered with nanoscopic carbon-based catalysts.

Electron-Cyclotron Laser Using Free-Electron Two-Quantum Stark Ra.ia.ion in a Strong Uniform a.ial Magnetic Field and an Alterna.ing a.ial Electric Field in a Voltage-Supplied Pill-Box Ca.ity

Chinese Physics Letters 2016年第3期33卷 56-59页

作者： S.h.Kim Church Road 9236 Dallas Texas 75231 USA

We consider the ra.ia.ion from the beam electrons traveling in a strong uniform a.ial magnetic field and an a.ial alterna.ing electric field of wavelength Aw generated by a voltage-supplied pill-box ca.ity. The beam electrons emit genuine laser ra.ia.ion that propagates only in the a.ial direction through free-electron two- quantum Stark ra.ia.ion. We find that laser ra.ia.ion takes place only at the expense of the a.ial kinetic energy when Aw 〈〈 c/（ωc/γ）, where ωc/γ is the rela.ivistic electron--cyclotron frequency. We formulate the laser power based on quantum-wiggler electrodyna.ics, and envision a laser of length lore with estimated power 0.1 GW/（ka） in the 10-4 cm wavelength range.

Design, simula.ion and construction of the Taban tokamak

引用

Plasma Science and Technology 2018年第4期20卷 112-120页

作者： h R MiRZa.i R AMROLLa.i Sta.istics of Department of Energy Engineering & Physics Amirkabir University of Tehran Tehran lran

This paper describes the design and construction of the Taban tokamak, which is located in a.irka.ir University of Technology, Tehran, iran. The Taban tokamak was designed for plasma.investiga.ion. The design, simula.ion and construction of essential parts of the Taban tokamak such as the toroidal field(TF) system, ohmic hea.ing(Oh) system and equilibrium field system and their power supplies are presented. For the Taban tokamak, the toroidal magnetic coil was designed to produce a ma.imum field of 0.7 T at R?=?0.45 m. The power supply of the TF was a130 kJ, 0–10 kV capa.itor bank. Ripples of toroidal magnetic field at the plasma edge and plasma center are 0.2% and 0.014%, respectively. For the Oh system with 3 ka current, the stray field in the plasma region is less than 40 G over 80% of the plasma volume. The power supply of the Oh system consists of two stages, as follows. The fast bank stage is a 120 μF, 0–5 k V capa.itor that produces 2.5 ka.in 400 μs and the slow bank stage is 93 mF, 600 V that can produce a ma.imum of 3 ka. The equilibrium system can produce uniform magnetic field at plasma volume. This system’s power supply, like the Oh system, consists of two stages, so that the fast bank stage is 500 μF, 800 V and the slow bank stage is 110 mF, 200 V.
