In this work, we present the experimental study of nanofluids’ electrophysical characteristics concentration dependencies specific behavior (nanoparticles Al2O3, ZnO and Fe2O3 in isopropyl alcohol) at low concentrations. The values a conductivity, electrical capacitance dielectric permittivity are measured depending on suspended particles’ for concentrated nanofluids far from percolation thresh...

Ion-exclusion/cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin using on acidic eluent, developed by Tanaka et al. in 1994, has been employed to monitor the quality of environmental water samples such as acid rainwater and river water, to analyze body fluid samples such as saliva, and to evaluate water purification by photocatalytic materials.1–8 One advantage of...

Application of ultrasonic methods to structural health monitoring requires a compromise between coverage and complexity, making it desirable to use as few transducers as possible to cover the largest area. Such a consideration leads to the use of very sparse arrays where transducers are spatially distributed over a large area and are permanently attached to the structure. For plate-like geometr...

Magnetic fringe fields emanating from a multiferroic heterostructure composite of Terfenol-D and lead magnesium niobate-lead titanate were utilized to actively tune a meander line microstrip ferrite phase shifter operating above ferrimagnetic resonance at C-band. Differential phase shifts of 65° were measured when tuned with an applied voltage to the multiferroic heterostructure. This demonstra...

2014 Recent experiments have shown that interdigital transducers can couple strongly to plate modes in piezoelectric composite membranes. In this paper the dispersive properties and the piezoelectric coupling (039403BD/03BD) to these plate modes are presented The various types of modes are identified and related to crystalline symmetry. Results are given for stiffened-shear modes in zinc oxide ...

One of the goals of modern spectroscopy is to invent techniques which detect neutral excitations that have been theoretically proposed. For superconductors, two point transport measurements detect the Andreev crossed reflection which confirms the existence of the Majorana fermions. Similar information can be obtained from a measurement using two piezoelectric transducers. One transducer measure...

We earlier described two taggers for French, a statistical one and a constraint-based one. The two taggers have the same tokeniser and morphological analyser. In this paper, we describe aspects of this work concerned with the definition of the tagset, the building of the lexicon, derived from an existing two-level morphological analyser, and the definition of a lexical transducer for guessing u...

In this paper, we present two approaches to synthesize nanostructured metal oxide semiconductors in a form of multi-layer thin films later assembled as conductometric gas-sensors. The first approach produces combination solid film tungsten trioxide (WO3) with nanoclusters cupric (CuO) prepared by magnetron-based gas aggregation cluster source (GAS). second method is two-step reactive magnetron ...
