The influence of solidification rate on the microstructure and distribution of solute during the solidification of Al-Cu alloy / Uticaj brzine očvršćavanja na mikrostrukturu i raspodelu primesa tokom očvršćavanja legure Al-Cu
(Savez inženjera metalurgije Jugoslavije, 1999)
In this paper investigation of the influence of solidification rate on the microstructure and distribution of solute during the solidification of Al-2.2%Cu by Vertical Bridgman method was performed. The experiments were ...
Enhancement of radiative lifetime in semiconductors using photonic crystals
(Elsevier, 1999)
Abstract
In this work we present a structure consisting of a semiconductor sample immersed between two one-dimensional photonic crystals, designed with the aim to investigate the possibility to increase radiative lifetime ...
The Characterization of Sintered SmCo5 Magnets
(Association for ETRAN Society, 1999)
During the investigation and design of laboratory model of a Sintered SmCo5 magnet, a group of methods for characterizing sintered and heat treated magnets was defined. The direct dependence of the magnetic properties of ...
Stereoselective transformation of cyclodecene-1,4-dione systems, derived from steroids, to the corresponding spiro-g-lactones. A semiempirical MO Study
(MDPI, 1999)
The thermal and acid-catalyzed intramolecular rearrangement of the (Z)- and (E)-cyclodecene-1,4-dione compounds deriving from steroids, 2a,b and 3a,b, respectively, proceeds stereoselectively to give the corresponding ...
13,14-Seco-steroids: A New Type of Modified Steroids Containing a Nine-Membered Ring
(Wiley, 1999)
Oxidations of 14α‐hydroxy‐5α‐cholestan‐3β‐yl acetate (5) with lead tetraacetate under thermal or photolytic conditions or in the presence of iodine proceed mainly by fragmentation of the C(13)−C(14) bond to give as the ...
