Chemical-Deposited Biaxially Textured Oxides YBCO, Y2O3 and LZO as Functional Layers for 2G HTSC Tapes

Synthesis, structure and luminescent properties of co-precipitated europium and aluminum hydroxides

“…can be observed. Splitting of a multiplet of 7FJ corresponds to the rule of intervals of Lande: the distance between levels with J and J+1 increases with increase in J, for example, the peak corresponding to transition 5D0→7F0 is located very close to 5D0→7F1, however the peak corresponding to transition 5D0→7F6 lies more than 50 nanometers further in IR the region, than 5D0→7F5 Change of a crystal basis, also leads to the shift of peaks that indicates stronger influence of the crystal field [11,16,17]. Crystalline europium (III) hydroxide, calcined at the temperature of the second endoeffect -280 °C, has: spatial group -hexogonal modification -P63/m; a=b=6.39, c=3.6582, α= β=90º, γ=120º; Z=2; Rrentgen.…”

“…Monoallyuminata of rare-earth elements, receive also by methods: joint sedimentation of oxalates, nitrates and hydroxides; chemical sedimentation from a steam phase (when receiving solid Ce1-xSrxMnO3 solutions); heterogeneous mixing of initial carbonates or oxides in water suspension; raspylitelny drying of mix of nitrate solutions of yttrium and aluminum [10]. Temperatures of the beginning of formation of aluminates having composition of mix 1:1 -1373-1450 К, 3:5 -1523-1873 K. No of a technique can be successfully used for receiving the RZE monoaluminates of yttric group which are breaking up at high temperatures [11][12][13].…”

Analysis of Characteristics of a Planar Broadband Double Ring Antenna

“…Реальные конструкции могут быть выполнены, например, из двух треугольных («Bowtie») [4] или двух круговых («восьмерка») копланарных элементов. На практике также применяется проводная зигзагообразная, иногда называемая «Bi-Quad», антенна [5].…”
