in this work, a novel hg2+ sensitive fluorescent chemosensor is constructed. the proposednano-chemosensor was prepared through the preparation of 3-(benzo[d]thiazol-2-yl)-7-hydroxy-2h-chromen-2-one functionalized silica nanoparticles which has high magnetization properties (btc-fe3o4@sio2). theûnal product was characterized by fourier transform infrared spectroscopy (ft-ir), thermal gravimetric...

We report the integration of a scanning force microscope with ion beams. The scanning probe images surface structures non-invasively and aligns the ion beam to regions of interest. The ion beam is transported through a hole in the scanning probe tip. Piezoresistive force sensors allow placement of micromachined cantilevers close to the ion beam lens. Scanning probe imaging and alignment is demo...

The application of a pulse shaped biasing method implemented to a capacitive probe is described. This approach delivers an accurate and simple way to determine ion fluxes in diverse plasma mixtures. To prove the reliability of the method, the ion probe was used in a different configuration, namely, a planar Langmuir probe. In this configuration, the ion current was directly determined from the ...

the hybrid molten/solid in2o3 - 30-48 wt.% bi2o3 oxide materials were studied with respect to their transport properties. the conductivities, oxygen ion transport numbers and oxygen permeation fluxes have been measured by using the four-probe dc, volumetric measurements of the faradaic efficiency and gas flow techniques, respectively. we show that the oxygen permeability of the hybrid molten/so...

A probe consisting of two poloidally separated triple probes and a Mach probe ~TMT probe! has been designed and installed on the H-1 heliac to study fluctuations. Mach probes are shown to be sensitive to the fluctuations in the electron density, electron and ion temperatures, and ion drift velocity. If the ion Larmor radius is much larger than the characteristic probe dimension, then the Mach p...

A new method of investigating structures below a surface in a dual beam microscope is presented. It comprises electrical measurements in depth profiles of sequential focused ion beam (FIB) cuts by the use of two or more nanomanipulators with plugged in probe needles. The sample is oriented such that the structures are observed with the electron beam while they are cut free with the FIB. The nan...

The ion saturation current to a spherical probe in the entire range of ion magnetization is computed with SCEPTIC3D, new three-dimensional version of the kinetic code SCEPTIC designed to study transverse plasma flows. Results are compared with prior two-dimensional calculations valid in the magnetic-free regime [I.H. Hutchinson, PPCF 44:1953 (2002)], and with recent semi-analytic solutions to t...
