Gaseous HCl and Cl-2 as well as CoCl2 . 6H(2)O and KI dissolved in methanol were added to fullerene-forming flat benzene/oxygen/argon flames burning at 75 mbar. The soot formed in the flames was collected and analysed by mass spectrometry using chemi

The impact of Cl-2 addition on the fullerene formation in acetylene/oxygen/argon flat flames burning at low pressure was investigated. The quantities of C-60 and C-70 in the soot were determined by HPLC after extraction with toluene. Negative ion mas

To achieve both high stability for scanning tunneling microscopy (STM) measurements and well‐defined tunnel current localization even on very rough surfaces, we have developed a new electrochemical procedure using CaCl2 etching and H2SO4 micro poli

Oxygen 2s spectroscopy can be especially useful in studies using synchrotron radiation (SR) where the deeper O 1s level frequently can not be excited. For tin oxides (SnO and SnO2), the weak emission from the O 2s levels has been previously found deg

To achieve both high stability during scanning tunneling microscopy (STM) measurements at atomic resolution and long‐range imaging of nonhomogeneous samples, we have developed a fully 2D vertical inertial nanopositioner which allows tunneling tip d

A design is proposed for a stable infrared source suited to absorbance measurements. The source is a parallelepipedic cavity of tantalum, heated to 2600 K, with an apparent emissivity in excess of 0.7. It is observed to be three times brighter at 300

Using well-defined samples of SnO and ${\mathrm{SnO}}_{2}$, we have focused our attention on the way the two tin oxides could be distinguished using x-ray-photoemission spectroscopy (XPS). Polycrystalline SnO, oxidized in air to give ${\mathrm{SnO}}_

The electronic properties of tin dioxide single-crystalline (110) surfaces have been studied in correlation with their structure by low-energy electron diffraction, angle-integrated and resonant photoemission using synchrotron radiation [ultraviolet
