Mixed cobalt(III) complexes with aromatic amino acids and diamine: Part V. Thermal investigation of (1,2-diaminoethane)bis(S-tyrosinato)cobalt(III) complex diastereomers
(Elsevier, 2005)
Thermal properties of (1,2-diaminoethane)bis(S-tyrosinato)cobalt(III) complex diastereomers are investigated by means of TG technique in 293-873 K temperature range. This is a first thermal study of [Co(S-aa) 2 en] + (S-aa ...
Reactivity of cyclohex-1-enylcarboxylic and 2-methylcyclohex-1-enylcarboxylic acids with diazodiphenylmethane in aprotic solvents / Reaktivnost cikloheks-1-enilkarbonske i 2-metilcikloheks-1-enilkarbonske kiseline sa diazodifenilmetanom u aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2000)
Rate constants for the reaction of diazodiphenylmethane with cyclohex-1-enylcarboxylic acid and 2-methylcyclohex-1-enylcarboxylic acid were determined in nine aprotic solvents, as well as in seven protic solvents, at 30 ...
Transition metal complexes with thiosemicarbazide-based ligands. LIII. [4-(2-Diphenylphosphino-a-ethoxybenzyl-κP)-S-methyl-1-(4-oxidopent-3-en-4- ylidene-κO)-thiosemicarbazido-κ 2 N 1 ,N 4 ]nickel(II)
(International Union of Crystallography, 2006)
The title compound, [Ni(C 28 H 30 N 3 O 2 PS)], crystallizes with two independent molecules in the asymmetric unit. The Ni II atoms are in significantly deformed square-planar environments formed by an ONNP donor set from ...
An intensity based optical fiber sensor for low velocity impact detection in unidirectional composites
(Taylor & Francis Ltd, Abingdon, 2000)
Prevention df serious damage of composite structures might be achieved by inspecting the structural integrity during exploitation. This paper decribes the design and development of a promising optical fiber sensor system ...
Influence of Cu on the mechanical properties of an Al-4.4wt%Mg alloy after ECAP
(Trans Tech Publications, Ltd., 2006)
Two Aluminium alloys, type AA5182 and AA5182+1.2wt% Cu, have been studied. The
second alloy in solution treated condition is 18% stronger than the first one. During ageing at 150°C or 200°C it shows a characteristic fast ...
Some observations on the shear fracture mode in AlMg6.5 alloy sheet
(Frankfurt : Werkstoff-Informationsgesellschaft mbH, 2001)
AlMg6.5 alloy sheet samples with different width to thickness ratio (w/t=2.5-8.3) were tested in uniaxial tension test. SEM observations revealed transgranular ductile dimple type of failure occured by shear process. It ...
The current distribution in an electrochemical cell. Part VII. Concuding remarks
(Serbian Chemical Society, 2002)
A new method for the determination of the ability of an electrolyte to distrubute uniformly current density in an electrochemical cell is proposed. It is based on the comparison of the current in cells in which the electrode ...
Application of the residual strength degradation model to carbon-epoxy composite
(Consultants Bureau/Springer, New York, 2008)
A residual strength degradation model for two orientations of fibers of carbon-epoxy composite is proposed. The model is constructed on the basis of an analysis of a gradual decrease in the residual strength of the composite ...
Investigation of antimicrobial activity of encapsulated essential oils
(8th Conference of the Yugoslav Materials Research Society, 2007)
Antimicrobial activity of essential oils obtained from many plants has been known for a long time. However, the use of essential oils as active components of biomedical textile have recently gained popularity and aroused ...
