Intramolecular hydrogen bonding in some acyclic alcohols 总被引:1,自引:0,他引:1
The extent of intramolecular hydrogen bonding, occurring in dilute CCl4 solutions, of members of the series (n = 2–5) HO.(CH2)n.OH and MeO.(CH2)n.OH has been determined. The results permit the interpretation of the patterns of hydrogen bonding in the three monomethyl ethers of butane-1,2,4-triol and in 1,4-dimethoxybutan-2-ol. In these compounds, where hydrogen bonding allows the formation of rings of different sizes the sequence of preference 5> 6> 7 was observed. 相似文献

Listeria monocytogenes is a facultative intracellular Gram-positive bacterium that is widely distributed in the environment. Despite being pathogenic at the species level, L. monocytogenes in fact comprises a diversity of strains from pathogenic ones that can result in disease and/or mortality to others that are relatively avirulent. The main goal of the current study was to answer the question on whether enhanced binding or attachment of L. monocytogenes to inert surfaces bears any relationship to pathogenicity in food-borne isolates. To answer this question, the nanoscale adhesion forces of eight L. monocytogenes strains that vary in their pathogenicity levels to a model surface of silicon nitride were quantified using atomic force microscopy. The strains used were the highly pathogenic (EGDe, 874, 1002, ATCC 19115), the intermediate pathogenic (ATCC 19112, ATCC 19118), and the non pathogenic (ATCC 15313 and HCC25). Our results indicate that the average nanoscale adhesion (in nN) and the 50% lethal dose (LD50) of strain virulence quantified in mice are logarithmically correlated according to: (nN) = −0.032 ln (LD50) + 1.040, r2 = 0.96. Such correlation indicates that nanoscale adhesion could potentially be used as a design criterion to distinguish between virulent and avirulent L. monocytogenes strains. Finally, stronger adhesion of virulent strains to inert surfaces modeled by silicon nitride might be a way for pathogenic strains to survive better in the environment and thus increase their likelihood of infecting animals or humans. 相似文献

The dissolution of Si(1-x)Ge(x)O(2) solid solutions under hydrothermal conditions was studied by in situ X-ray absorption spectroscopy. Experiments were performed at the Ge K-edge using a high-pressure cell mounted on the FAME beamline of the European Synchrotron Radiation Facility. Spectra in both transmission and fluorescence mode were collected in isobaric conditions (100 and 150 MPa) up to 475 °C. The local atomic structure around the Ge atom was investigated as a function of the temperature and in pure water and sodium hydroxide solutions. In pure water, the solubility of the cristobalite-type Si(0.8)Ge(0.2)O(2) increases with the temperature and the Ge atom is in 4-fold coordination. In a sodium hydroxide aqueous solution, a complex between Ge and Na atoms forms and gives rise to precipitation of sodium germanates. Under these conditions, the Ge content in the solution decreases with increasing temperature. These results show that a sodium hydroxide aqueous solution, usually used for quartz crystal growth, is not suitable for Ge-containing crystals. The dissolution kinetics and phase transformation of the solid solution were studied as a function of the atomic fraction of Ge. Ge-rich solid solutions dissolve and transform to stable phases faster than Ge-poorer composition, giving rise to important variations of the Ge content in solution. 相似文献
