Parallel alignment of water and aryl rings-crystallographic and theoretical evidence for the interaction
(Royal Soc Chemistry, Cambridge, 2008)
Analysis of crystal structures from the Cambridge Structural Database (CSD) that involve close contact between water and aryl rings revealed the existance of conformations where the water molecule or one of its O-H bonds ...
Photoacoustic elastic bending method: Investigation of the surface recombination states
(26th International Conference on Microelectronics, Proceedings, MIEL 2008, 2008)
The recombination processes of surface modified Si samples by the PA elastic bending method were investigated. The experimental PA elastic bending signals were measured by using special constructed PA cell (the gas-microphone ...
The electrochemical behavior of erythromycin A on a gold electrode
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The reactivity of erythromycin (pure) was investigated on a gold electrode in neutral electrolyte by cyclic voltammetry. The resulting structural changes were observed with HPLC and FTIR spectroscopy by analyzing the bulk ...
Simultaneous production of pullulan and biosorption of metals by Aureobasidium pullulans strain CH-1 on peat hydrolysate
(Elsevier Sci Ltd, Oxford, 2008)
It was demonstrated that during the growth of Aureobasidium pullidans strain CH-1 on the acid hydrolysate of peat from the Vlasina Lake, the content of metals (Cu, Fe, Zn, Mn, Pb, Cd, Ni and Cr) decreased due to biosorption. ...
Antiglioma action of xanthones from Gentiana kochiana: Mechanistic and structure-activity requirements
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The present study identifies xanthones gentiakochianin and gentiacaulein as the active principles responsible for the in vitro antiglioma action of ether and methanolic extracts of the plant Gentiana kochiana. Gentiakochianin ...
Morphologies of electrochemically formed copper powder particles and their dependence on the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2008)
Copper powder particles formed by electrolysis under different quantities of evolved hydrogen were analyzed using the scanning electron microscopy (SEM) technique. It was found that the structure of the powder particles ...
Metal nanowire arrays with ultralow or negative effective permittivity for adsorption-based chemical sensing
(Institute of Electrical and Electronics Engineers Inc., 2008)
We investigated wire-mesh media with plasma-like dispersion of dielectric permittivity as a potential medium for nanoplasmonic sensors utilizing adsorption of chemical, biochemical or biological analytes. Such structures ...
Lipids and cholesterol content in pigs' neck and the activity of glutathione-dependent enzymes / Sadržaj masti i holesterola u vratu svinja i aktivnost glutation zavisnih enzima
(Tehnologija mesa, 2008)
Pigs' neck meat is predominantly used for barbecues. In order to prevent oxysterols formation during thermal preparation, it is important to be aware of the content of fats, cholesterol and the activity of lipid peroxide ...
Diagnostic of silicon piezoresistive pressure sensors by low frequency noise measurements
(Sensors and Actuators, A: Physical, 2008)
Low frequency noise measurements can be used as a tool in diagnostics of silicon diaphragm-based piezoresistive pressure sensors after the sensor encapsulation and oil filling process are finished. We measured noise in ...
The effect of hydrogen co-deposition on the morphology of copper electrodeposits. II. Correlation between the properties of electrolytic solutions and the quantity of evolved hydrogen
(Elsevier, 2008)
Formation of irregular deposits by electrodeposition from acid sulfate solutions of various H2SO4 concentrations was examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
