In this work, stabilized f-ZrO 2 ceramic samples with the compositions of (Zr 0.82 Y 0.09 Eu )O 1.91 , Tb and 0.045 were studied. The elemental composition was studied by electron probe microanalysis, luminescent properties local cathodoluminescence (CL). An analysis 3+ CL spectra confirmed stabilization cubic phase in ceramics at room temperature. study obtained spectra, 5 D 4 - 7 F band luminescence decay kinetics, images excitation showed europium sensitization terbium .

Graphene-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...

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...
متن کاملVariation-Based Linearization of Nonlinear Systems Evolving on SO(3) and S<sup>2</sup>
In this paper, we propose a variation-based method to linearize the nonlinear dynamics of robotic systems, whose configuration spaces contain the manifolds S and SO(3), along dynamically-feasible reference trajectories. The proposed variation-based linearization results in an implicitly time-varying linear system, representing the error dynamics, that is globally valid. We illustrate this metho...

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...
