Isolation and possible composition of glucosylceramides from Paracoccidioides brasiliensis
(Assoc Bras Divulg Cientifica, 1996-11-01)
Twelve different species of neutral monohexosyl ceramides (CMHs) and two species of neutral monohexosyl ceramides were isolated from mycelium and yeast forms of Paracoccidioides brasiliensis, respectively, by a combination ...

Ion induced high energy electron emission from copper
(Elsevier Science, 2008-12)
We present measurements of secondary electron emission from Cu induced by low energy bombardment (1–5 keV) of noble gas (He+, Ne+ and Ar+) and Li+ ions. We identify different potential and kinetic mechanisms and find the ...
Recoil-ion fractions in collisions of keV Ar+ and Kr+ ions with clean and adsorbate covered GaAs(1 1 0) surfaces
(Elsevier Science, 2002-12)
Ion scattering and recoiling spectroscopy with time of flight analysis is used to study the ion fractions of Ga and As atoms recoiled in collisions of 5 keV Ar+ and Kr+ with clean GaAs(1 1 0) and with GaAs(1 1 0) covered ...
Identification of mechanisms of ion induced electron emission by factor analysis
(Elsevier Science, 2005-04)
Introducing the use of the Factor Analysis method to analyze electron emission spectra we identify different mechanisms for electron emission from clean Al surfaces under bombardment by Ar+ and Li+ ions. The analysis of ...
Analysis by Mass Spectrometry of the Polar Lipids from the Cellular Membrane of Thermophilic Lactic Acid Bacteria
(Molecular Diversity Preservation International, 2000-03)
Fast atom bombardment (FAB) technique was employed to determine the structure of polar lipids from the cellular membrane of Lactobacillus delbruekii ssp. bulgaricus and Streptococcus salivarius ssp. thermophilus. Analysis ...
Synthesis, structure and electrochemical properties of the cationic complex tris-(imidazolidine-1,10-phenanthroline)iron(II)
(2009)
The complex [FeII(Imz-phen)3](PF6)2, (Imz-phen = imidazolidine-[4,5-f]-1,10-phenanthroline) has been prepared and characterized using X-ray diffraction, UV–vis and IR spectroscopy, elemental analysis, fast atomic bombardment ...
A study of chlorophyll-like and phycobilin pigments in the C endosymbiont of the apple- snail Pomacea canaliculata
(Instituto de Histología y Embriología, 2012-08)
Pigments present in the brown-greenish C morph of an intracellular endosymbiont of Pomacea canaliculata were investigated. Acetone extracts of the endosymbiotic corpuscles showed an absorption spectrum similar to that of ...
Chemical ecology and bioactivity of triterpene glycosides from the sea cucumber Psolus patagonicus (Dendrochirotida: Psolidae)
(Cambridge University Press, 2008-08)
Information on the chemical ecology and bioactivity of chemical compounds present in the sea cucumber Psolus patagonicus is provided through an interdisciplinary approach. The specimens studied were collected from two ...
