Normally, in analytical GD-MS, the doubly charged metallic ion signals from the sample are several orders of magnitude less than the corresponding singly charged signals. However, we have observed that using a neon plasma, the M++ signals of some ele

We report results of comprehensive studies using the Nu Instruments Astrum high-resolution glow discharge mass spectrometer (GD-MS) and optical emission spectrometry (OES) to investigate the relative importance of discharge mechanisms, such as Pennin

Models establishing relationships between electrical resistivity and dopant densities of silicon wafers/bricks are not applicable for compensated-Si, such as upgraded metallurgical grade silicon UMG-Si. To date, no satisfactory theoretical model has

Trace elemental compositions of platinum-aluminide (PtAl) coatings and their depth profiles on nickel base superalloys were studied using high-resolution glow discharge mass spectrometry. Concentration profiles for selected trace elements were invest

In a previous paper [Carbon, 1997, 35, 83]it was shown for a series of activated carbons with acidic behavior that surface characterization with a continuous pK distribution was possible based on potentiometric titration provided that several experim

The lithium form of taeniolite, intercalated with hydroxyaluminum and hydroxyaluminum−zirconium cations, served as the molecular template for carbon−mineral nanocomposites and derived carbons. The ...

Mg-Al layered double hydroxides have been synthesized and 1,5-naphthalene disulfonate dianions have been intercalated; the organic molecules were carbonized within the layered framework. For comparison, a reference carbon was prepared from the sodium

The adsorption isotherms for CH{sub 4}, CF{sub 4}, and SF{sub 6} are measured at three or four temperatures near ambient on three commercial activated carbons. The data are reduced using a virial-type equation of adsorption. Using this equation, isos

Carbons obtained by carbonization of polyfurfuryl alcohol within the smectite and taeniolite matrices were studied by sorption methods. The sorption of nitrogen at 77 K showed only small differences in the pore structure ofthese materials related to
