GeO desorption from a GeO2/Ge stack is a critical concern in Ge metal oxide semiconductor field effect transistors (MOSFETs). In this contribution, we focus on a uniform-desorption region and unveil the GeO desorption mechanism from a GeO2/Ge stack by 73Ge and 18O isotope tracing in thermal desorption spectroscopy (TD…
Carbamazepine is a widely used anti-epileptic drug with narrow therapeutic range. Many methods have been developed for monitoring the serum drug level. Differential pulse voltammetry ( DPV ), an electrochemical method advantaged by simple, inexpensive, and relatively short analysis time, has recently been developed fo…
Experimental results showing evidence for the development of filaments in plasma of the Globus-M spherical tokamak have been obtained by the method of Doppler reflectometry. The correlation between the reflectometric data and results of probe measurements at the periphery of discharge in the tokamak is found. Experime…
The shape and evolution of periodically folded threads are experimentally examined in a microfluidic network. The fluidic system is designed for the production and lubricated transport of very uniform folds. To investigate the influence of viscosity and interfacial tension on buckling deformations, multiphase flows ar…
We investigate the thermoelectric effects of an Aharonov-Bohm (AB) interferometer with a quantum dot (QD) embedded in each of its arms, where the intra-dot Coulomb interaction between electrons in each QD is taken into account. Using Green's function methods and the equation of motion (EOM) technique, we find that the…
Bouncing droplets on a vibrated liquid bath can interact via the surface waves they emit and form various types of stable crystalline clusters. When increasing the forcing acceleration over an onset value, the aggregates present a global and spontaneous vibration mode. Here, we investigated experimentally these vibrat…
Nearly monodispersed CuIn 0.7 Ga 0.3 Se 2 (CIGS) nanocrystals were successfully prepared using the thermal decomposition of copper, indium (In), gallium (Ga), and selenium–oleylamine (OLA) complexes via the heating‐up process. The phase formation sequence was CuSe→CuInSe 2 →CIGS. The CIGS nanocrystals synthesized usin…
The new transition-metal manganite Cu 0.1 Ni 0.8 Co 0.2 Mn 1.9 O 4 ceramics for temperature sensors with improved functional reliability are first proposed. It is established that the amount of additional NiO phase in these ceramics extracted during sintering play a decisive role. This effect is well revealed only in…
Temperature sensitive thick films based on spinel-type NiMn 2 O 4 -CuMn 2 O 4 -MnCo 2 O 4 manganites with p- and p + -types of electrical conductivity and their multilayer p + -p structures were studied. These thick-film elements possess good electrophysical characteristics before and after long-term ageing test at 17…
We theoretically analyze the possibility of using certain relaxation functions (relaxation kernels) for dissipative processes discovered in the internal friction spectra of two-phase unordered glassy systems at temperatures higher than the vitrification temperature. It has been found that the most acceptable functions…
A procedure was developed for preparing synthetic schoepite [(UO2)8O2(OH)12](H2O)12 (UO3·2.25H2O). The dehydration and thermal decomposition of this compound were studied by X-ray diffraction, IR spectroscopy, and differential scanning calorimetry. The relationship between schoepite and other hydrated forms of uranium…
The present study introduces atomic force microscopy (AFM) as a tool for characterization of marine gel network and marine biopolymers self-assembly, not accessible by other techniques. AFM imaging of marine gel samples collected in summers 2003 and 2004 in the northern Adriatic Sea provided insight into molecular org…
Ultrasound treatment is a feasible option for membrane cleaning but its exploitation is possible only if membranes withstand the treatment. In this review an overview of the literature concerning the membrane tolerance to ultrasonic irradiation is provided. The amount of available information concerning stability of m…
Summary In this work, we propose a 3 dimensional (3D) numerical model to predict the piezoresistivity behaviours of a nanocomposite material made from an insulating polymer filled by carbon nanotubes (CNTs). This material is very hopeful for its application in highly sensitive strain sensor by measuring its piezoresis…
We calculated the main dynamic parameters of the spin polarized current induced magnetic vortex oscillations in nanopillars, such as the range of current density, where vortex steady oscillations exist, the oscillation frequency and orbit radius. We accounted for both the non-linear vortex frequency and non-linear vor…
Simple compounds like HCN, which have one C and one N, are proposed as the probable precursors for biomonomers. Formamide, a hydrolysis product of HCN, is known as the precursor of various biologically important compounds, for example, nucleobases (purines and pyrimidines). In this paper, we report our results on the…
We report the effect of Mn doping on temperature-dependent magnetic properties of L10 FeMnPt (001) epitaxial films. (001) textured L10 Fe50−xMnxPt50 (x = 0, 5, 10, 15, 20 at. %) films were prepared by cosputtering Fe, Pt, and Mn onto MgO single crystal substrates at 550 °C. θ–2θ XRD scans indicated the lattice paramet…
An extensive body of preclinical and clinical data has shown that administration of adult multipotent marrow stromal cells (MSCs) effectively ameliorates experimental and clinical conditions of many different organ systems. Differentiation into organ parenchymal cells, however, is very rare, and the main mechanism for…
Phase-resolved x-ray ferromagnetic resonance (XFMR) has been measured in fluorescence yield, extending the application of XFMR to opaque samples on opaque substrates. Magnetization dynamics were excited in a Co50Fe50(0.7)/Ni90Fe10(5) bilayer by means of a continuous wave microwave excitation, while x-ray magnetic circ…
An improved method of confocal/polarized Raman spectroscopy is proposed, which enables the determination of the full set of tensor components in three dimensionally graded stress fields in sapphire single-crystal. From the experimental side, the proposed method employs a simple back-scattered configuration for the opt…
