Max-Planck-Institute for Chemical Ecology, Hans-Knoll-Strasse 8, D-07745 Jena, Germany. pohnert@ice.mpg.de The biosynthesis of caulerpenyne 1 was studied in the invasive green alga Caulerpa taxifolia. The investigation was performed on intact algae with st ...
Railway ballast provides both the foundation and drainage for railway track. It can become heavily contaminated with diesel fuel due to leakage and spillage. Typical analytical methods for soils may not be applicable to the assessment of ballast. The effic ...
The fluorescence resonance energy-transfer (FRET) process was studied between donor dye mols. deposited on the sample surface and acceptor dye mols. deposited on the tips of scanning near-field and at. force microscopes. The FRET process was obsd. only whe ...
Fluorescence resonance energy transfer (FRET) was obsd. between donor dye mols. deposited onto the sample surface and acceptor dye mols. deposited onto the scanning near-field optical microscope (SNOM) or at. force microscope tip. FRET was obsd. only when ...
Unsaturated Polyester (UP) resins are extensively used as a matrix for the production of composites due to their low cost and versatility. Their significant polymerization shrinkage has however a negative impact on the dimensional stability of the molded p ...
Relaxor ferroelectric thin films exhibit a drastic reduction in the dielectric constant and associated properties in the thin film form, even for thicknesses in the micron range, which are essentially infinity for the size effects typically investigated in ...
The influence of residual ethanol on metab. of food grade Gluconacetobacter xylinum I 2281 was investigated during controlled cultivations on 35 g/l glucose and 5 g/l ethanol. Bacterial growth was strongly reduced in the presence of ethanol, which is unusu ...
The electropolishing of a B-doped diamond (BDD) film deposited by CVD was studied in HOAc-H2SO4 media. The electropolished surface was characterized by SEM, XPS, and electrochem. measurements. In 1 M H2SO4 no polishing of the surface occurred even after pr ...
The reductive cleavage of Me vinyl-b-ionyl ether or the deprotonation of 3,2',6',6'-tetramethyl-5-(1-cyclohexenyl)-1,3-pentadiene gives rise to an organometallic C15 species that combines selectively with a variety of electrophiles at the terminal chain po ...
2,2-Diethoxyvinyllithium (I) can be readily generated from 2-bromo-1,1-diethoxyethylene by treatment with butyllithium. Reaction of I with electrophiles e.g. chlorotrimethylsilane gives Me3SiCH:C(OEt)2. When dissolved in THF, I can be stored at -25 DegC fo ...
