The ratio of oxygen atoms to ions (O /O +) generated during electron stimulated desorption (ESD) from V20 s and oxidized V foil has been investigated. Desorbates were probed directly with high resolution quadrupole mass spectrometry. X-ray photoelectron spectroscopy was used as an indirect probe to measure the ESD induced surface oxygen loss. Despite the number of ESD target preparation methods...

A new and inexpensive lignocellulose/montmorillonite (LNC/MMT) nanocomposite was prepared by a chemical intercalation of LNC into MMT and was subsequently investigated as an adsorbent in batch systems for the adsorption-desorption of Ni(II) ions in an aqueous solution. The optimum conditions for the Ni(II) ion adsorption capacity of the LNC/MMT nanocomposite were studied in detail by varying pa...

The interaction of nitrogen with a Re(OOO1) surface has been studied by low energy electron diffraction (LEED), thermal desorption spectroscopy (TDS), Auger electron spectroscopy (AES) and electron energy loss spectroscopy (ELS). Two LEED patterns have been observed upon adsorption of nitrogen on Re(OOO1). One, identified as the 4 x 1, is induced by N, exposure at 115 K and is related to the or...

cobalt (ii) chloride was used as a precursor to prepare co 3 o 4 nanotubes in reverse micelles. tween 80 was added as surfactant. the products were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy. the diameter of co 3 o 4 nanotubes was about 58 nm and the average length of them was around 261 nm. the study provides a simple and e...

A sulfhydryl-lignocellulose/montmorillonite (SLT) nanocomposite was prepared using a chemical intercalation reaction. The SLT nanocomposite was characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), and Transmission Electron Microscopy (TEM), the results demonstrated that an intercalated-exfoliated nanostructure was formed i...

The interaction of borazine (NsB,H,) with a Re(0001) surface has been studied by low energy electron diffraction (LEED), thermal desorption spectroscopy (TDS), Auger electron spectroscopy (AES) and electron energy loss spectroscopy (ELS). Two LEED patterns have been observed following borazine adsorption and annealing. One is the 2 X 2 structure, assigned to arise from atomic nitrogen. The othe...

in this work, we report a new well dispersed molybdenum complex attached through the mediation of aminopropylsilyl groups on the surface of multi-walled carbon nanotubes (mwcnts). the prepared hybrid nanomaterial was characterized with different physicochemical methods such as fourier transform infrared and atomic absorption spectroscopies, transmission electron microscopy, energy-dispersive x-...

We have measured the kinetic energy distributions of neutral halogen atoms emitted due to electron-stimulated desorption (ESD) from In-doped (001)KBr single crystals. The concentration of In + in investigated samples varied between 10” and 10” particles/cm3. The measurements were performed at target temperature of 150°C. In all cases the energy spectra consist of two peaks. The distribution of ...
