Sphingomonas paucimobilis was isolated from tracheal secretions of a total of 85 mechanically ventilated babies in a neonatal intensive-care unit (NICU) during a two-year-period. None of the neonates developed pneumonia or sepsis. After each increase in the fluctuating number of S. paucimobilis isolates, extra attention was paid to hand hygiene and to the(More)
A new reaction sequence for the chemical functionalization of single-wall carbon nanotubes (SWNTs) consisting of the nucleophilic addition of t-BuLi to the sidewalls of the tubes and the subsequent reoxidation of the intermediates t-Bu(n)SWNT(n-) leading to t-Bu(n)SWNT was developed. During the formation of the t-Bu(n)SWNT(n-), a homogeneous dispersion in(More)
The width of phonon lines in the Raman spectra of ideal isotopically pure solids is determined by inelastic scattering processes. In solids that contain a mixture of different isotopes of one atomic constituent, elastic scattering due to isotopic mass disorder opens up decay channels that result in additional line broadening. We use different polytypes of(More)
