Solvent and structural effects on the kinetics of the reactions of cycloalkenylcarboxylic and cycloalkenylacetic acids with diazodiphenylmethane
(Wiley, Hoboken, 2005)
The rate constants for the reaction of different cycloalkenylcarboxylic, cycloalkenylacetic acids, and phenylacetic acid with diazodiphenylmethane were determined in 12 aprotic solvents at 30 degrees C. in order to explain ...
Through thickness optimal design of glass-epoxy composite pressure vessel / Optimizacija strukture laminarnog kompozitnog materijala po debljini zida posude pod pritiskom
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
Mechanical loading of pressure vessels mainly comes from pressure (inner and outer) under which is vessel subjected. Tension which appears changes according to the thickness of the wall. Thanks to the its specific structure, ...
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 ...
Low-temperature tension properties of glass-epoxy composite materials / Određivanje zateznih svojstava staklo-epoksi kompozitnih materijala na niskim temperaturama
(Faculty of Technology, Novi Sad, 2005)
The aim of this paper was to present the determination of tensile strength Rm and modulus of elasticity Et of glass-epoxy composites at two different temperatures (at room temperature t=20°C, and at t =-50°C). Standard ...
