Lubricant evaluation method for FDBs using TOF-SIMS

Microsystem Technologies, 2002
With the increase in recording density and data transfer rate of hard disk drive (HDD), fluid dynamic bearing (FDB) motors have been introduced due to their silence and high rotation accuracy. Although lubricant plays a major role in the development of FDB motors, it is extremely difficult to perform thorough evaluation because the quantity of ...

A Spectral Integral Method (SIM) for Layered Media

IEEE Transactions on Antennas and Propagation, 2006
A spectral integral method is presented for electromagnetic scattering from dielectric and perfectly electric conducting (PEC) objects with a closed boundary embedded in a layered medium. Two-dimensional layered medium Green's functions are computed adaptively by using Gaussian quadratures. The singular terms in the Green's functions and the non-smooth

SIMS methods in reactivity studies on metal oxides

Inorganica Chimica Acta, 1995
Abstract A SIMS (secondary ion mass spectrometry) study of IrO2/RuO2/TiO2 mixed oxide films and PbO2 films synthesized by thermal and electrochemical processes, respectively, reveals interesting cluster ions that may be very important in evaluating component reactivity between different metal oxides and with trapped ions or neutral particles present ...

Testing and Validation of Nuclear Fuel Composition Using SIMS Method

Journal of Nuclear Engineering and Radiation Science, 2021
Abstract Correct mathematical models of a reactor core in benchmarking of reactor physics experiments require detailed knowledge of exact isotopic composition of fuel pellets, especially the presence of neutron absorbers. Among them, knowledge of 234U and 236U abundance in fuel is important, because their absorption is considerably ...

Spatial statistics and interpolation methods for TOF SIMS imaging

Applied Surface Science, 2006
Multivariate statistical methods such as principal components analysis (PCA) and factor analysis (FA) have been applied to mass spectral data to extract higher quality information from ion intensities in the mass spectrum. This often leads to better image quality in the resulting image analysis of principal components or factors.

A rapid method for detecting barbiturates in serum using EI-SIM

International Journal of Legal Medicine, 1994
A simple and rapid method for analysis of barbiturates in serum has been developed. In order to extract and clean barbiturates in serum, a separation column packed with Extrelut and Florisil was used, and the eluate was directly analyzed by means of electron impact selected ion monitoring (EI-SIM).

A NEW APPROACH OF THE SIMS METHOD FOR METAL CLUSTERS

Surface Review and Letters, 1996
The size distributions of ( CsI )n Cs +, [Formula: see text], and [Formula: see text] (M: alkali metal, j=1, 2, 3, 4, 5) clusters were obtained using secondary-ion mass spectrometry. The sizes of stable neutral clusters ( CsI )n and ( Hg )n clusters were determined from the mass spectra of cluster ions ( CsI )n Cs + and ( Hg )nM+. The magic numbers of

SIMS Combined with Other Methods of Surface Analysis

1984
Like all methods of surface analysis, SIMS provides only fragmentary information and therefore profits by combination with complementary techniques. Comparable results can only be obtained if these additional methods are applied to the same surface simultaneously or sequentially in one UHV system.
