چکیده
Yttrium aluminum garnet (YAG) ceramics doped with Ce3+ was prepared by dry compaction using the common uniaxial pressing under powerful ultrasound assistance (PUA). The structure and luminescent properties of sintered were investigated. It demonstrated that ultrasonic assistant during has a positive effect on structural characteristics YAG: ceramics. material consolidation is very intensive accompanied decrease in number pores grain growth at sintering temperature 1650 ºC. luminous efficiency YAG:Ce3+ vary from 120 to 219 lm/W (without treatment) 250 (prepared conditions) closely related phase purity implicitly temperature.

متن کاملGraphene-on-Diamond Devices with Increased Current-Carrying Capacity: Carbon sp<sup>2</sup>-on-sp<sup>3</sup> Technology
Graphene demonstrated potential for practical applications owing to its excellent electronic and thermal properties. Typical graphene field-effect transistors and interconnects built on conventional SiO2/Si substrates reveal the breakdown current density on the order of 1 μA/ nm (i.e., 10 A/cm), which is ∼100× larger than the fundamental limit for the metals but still smaller than the maximum a...
متن کاملNa<SUP>+</SUP>-K<SUP>+</SUP>ATPase in Human Brain Tumors
Na+-K+-stimulated adenosine triphosphat s (Na+-K+ATPase) activities were measured in 12 human brain tumors and surrounding tissue (white matter and cortex) by the colorimetric deter mination of hydrolyzed inorganic phosphorus (Pi) from adenosine triphosphate (ATP). In glioma cases, the brain microvessels, filial component, and neurons were isolated fr...

The reaction dynamics of the boron monoxide radical (BO; XΣ) with diacetylene (C4H2; XΣg) were investigated at a nominal collision energy of 17.5 kJ mol−1 employing the crossed molecular beam technique and supported by ab initio and statistical (RRKM) calculations. The reaction is governed by indirect (complex forming) scattering dynamics with the boron monoxide radical adding with its boron at...
متن کاملQUANTALE-VALUED SUP-ALGEBRAS
Based on the notion of $Q$-sup-lattices (a fuzzy counterpart of complete join-semilattices valuated in a commutative quantale), we present the concept of $Q$-sup-algebras -- $Q$-sup-lattices endowed with a collection of finitary operations compatible with the fuzzy joins. Similarly to the crisp case investigated in cite{zhang-laan}, we characterize their subalgebras and quotients, and following...
