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.
Synthesis and evaluation of several cathechol bioisosteres as potential dopamine receptor ligands
(Elsevier, 1991)
Derivatives of benzimidazole (I), benzimidazolone (II), benzimidazolethione (III), 2,3-dihydroxyquinoxaline (IV) and the noncyclic acetamide (V) and t rifluoroacetamide (VI) of the corresponding 1,2-pheny-lenediamiane were ...
The effect of the pause-to-pulse ratio on the morphology of metal powder particles electrodeposited by square-wave pulsating overpotential
(Switzerland : Springer Nature, 1991)
It is well known that the deposition conditions such as
bath composition, hydrodynamic regime, temperature,
current density, exhibit a strong effect on the grain size
and the morphology of electrodeposited metal ...
Depolarization end point can glassy carbon electrodes: Microscale coulometry of thioglycollic acid
(Wiley, 1991)
An externally unpolarized twin couple of glassy carbon electrodes, undergoing different pretreatments, and connected to nothing but a recorder, was engaged for simple and fast end‐point detection of electrometric titrations ...
Isothermal vapor phase epitaxy of (Hg,Cd) Te from Te-rich Hg1-yTey source(Article)
(Elsevier, 1991)
The method of isothermal vapor phase epitaxy (ISOVPE) of Hg1-xCdxTe layers with fixed surface composition is presented. The epitaxial growth was performed from a Te-rich Hg1-yTey (y > 0.5) liquid source, in an open tube, ...
Single-particle settling velocity through liquid fluidized beds
(Elsevier, 1991)
Single-particle settling velocities through waterfluidized
beds have been studied experimentally using
a standard fluidtzation column 40 mm in diameter.
All the particles used were spherical. The combinations
of ...
Sesquiterpene lactones from Achillea crithmifolia
(Elsevier, 1991)
The isolation of guaianolides rupicolin-A, rupicolin-B, their acetates and a new germacranolide 1β,10α-epoxy-3β,9β-diacetoxy-11α,13-dihydrocostunolide, identified by means of PS DQF COSY and PS NOESY, from Achillea ...
Identification of intermetallic compounds in thin layers of electrodeposited Cu–Cd alloys using electrochemical techniques
(USA :Taylor & Francis INC, 1991)
An attempt was made to analyse the phase structure of thin layers of electrodeposited Cu–Cd alloys using anodic linear sweep voltammetry combined with a potentiostatic pulse technique (ALSV–PPT). The results were compared ...
Structural effects in electrocatalysis. Oxidation of D-glucose on single crystal platinum electrodes in alkaline solution
(Elsevier, 1991)
Electrochemical oxidation of D-glucose has been studied in 0.1 M NaOH on single crystal platinum electrodes with thirteen different orientations. The reaction rate depends strongly on the crystallographic orientation of ...
The electro-oxidation of glycerol on the gold(100)-oriented single-crystal surface and poly crystalline surface in 0.1 M NaOH
(Elsevier, 1991)
Studies of chemical and electrochemical reactions at well-defined surfaces provide additional data on surface reactivity and guidelines for the understanding and design of catalytic materials. In this work, the oxidation ...
