Sesquiterpene lactone from Achillea crithmifolia
(Elsevier, 1993)
Achillea crithmifolia Waldst. et Kit. (Asteraceae) is used in folk medicine against the same disorders as the well known Achillea millefolium L. (Asteraceae). Hitherto, four guaianolides (rupicolin-A and -B and their ...
Informational spectrum method applied to the investigation of the enzymatic activity of different alpha amylases / Primena metode informacionih spektara u ispitivanju enzimatskih različitih alfa amilaza
(Serbian Chemical Society / Srpsko hemijsko društvo, 1991)
A series of eight alpha amylases (EC 3.2.1.1) of known primary structure were investigated using the Informational Spectrum Method (ISM) for the purpose of predicting new enzymes with increased efficiency.
The influence of OH- chemisorption on the catalytic properties of gold single crystal surfaces for oxygen reduction in alkaline solutions
(Elsevier, 1996)
Oxygen reduction on gold single crystal electrodes of various orientations, Au(hkl), in 0.1 M NaOH was studied by rotating disk electrode and rotating disk ring electrode techniques, with a goal to correlate the physical ...
Kinetic and mechanistic study of methanol oxidation on a Pt(110) surface in alkaline media
(Elsevier, 1998)
The comparative study of methanol oxidation on a Pt(110) surface was carried out in bicarbonate, carbonate and sodium hydroxide solutions. It was shown that OH- electrosorption precedes the oxide layer formation in sodium ...
Surface diffusion of clusters and thin film growth
(Elsevier, 1995)
An analogy between the behavior of real gases and the behavior of clusters deposited on a surface has been established. A relation similar to the Van der Waals equation was used, with the variables corresponding to the ...
The influence of pH on reaction pathways for O2 reduction on the Au(100) face
(Elsevier, 1996)
Oxygen reduction on the Au(100) face was studied by the rotating disk-ring electrode technique in solutions of anions which adsorb strongly on gold (HSO4-/SO42- and/or OH-) over the entire pH range. The specific adsorption ...
Properties of activated alumina obtained by flash calcination of gibbsite
(Elsevier, 1992)
On exposing gibbsite, with granulation below 10 μm to flash calcination of 0.5 s in the regime of pneumatic transport and at temperatures above 883 K, a microcrystalline material with a high degree of amorphization was ...
Effect of substituents on the 13 C chemical shifts of the azomethine carbon atom of N-(phenyl substituted) pyridine-4-aldimines
(Elsevier, 1999)
13 C chemical shifts of the azomethine carbon atom for N-(substituted phenyl)pyridine-4-aldimines, 4-Py-CH=N-C 6 H 4 -X, X having a wide range of substituent effects, have been determined in CDCl 3 solution. Exceptionally ...
Nanoscale pattern formation during electrodeposition: Ru on reconstructed au(111)
(USA : American Physical Society, 1999)
Scanning tunneling microscopy results on Ru electrodeposition on reconstructed Au(111) are presented, which show a novel type of site-selective nucleation on this surface. At potentials around 0.0 V vs the Ag/AgCl reference ...
Surface morphology and the response of piezoelectric gas sensors
(Elsevier, 1995)
The surface morphology of gold electrodes on piezoelectric quartz crystals was characterized by scanning electron microscopy and scanning tunnelling microscopy. Sensors with various coating materials as polymers, liquid ...
