Highly oxygenated guaianolides from Anthemis cretica subsp. cretica
(Elsevier, 1999)
Two new guaianolides, i.e. anthemolide B and 8-O-angeloyl-9-O- acetylanthemolide B, in addition to 12 known closely related guaianolides were identified in the aerial parts of the flowering plant Anthemis cretica subsp. cretica.
Integrated multicolor detector utilizing 1-D photonic bandgap filter with wedge-shaped defect
(Society of Photo-Optical Instrumentation Engineers (SPIE), 1999)
Abstract
We propose a single-chip multicolor photodetector for (3-5) μm range based on a linear IR semiconductor detector array with an integrated 1-D photonic bandgap (PBG) filter. A wedge-shaped defect slab (corresponding ...
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 ...
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 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 ...
Electrochemical Deposition and Phase Structure of Electrodeposited Ni-W Alloys / Elektrohemijsko taloženje i fazna struktura legura Ni-W
(Serbian Chemical Society, 1999)
The induced deposition of W in the presence of iron-group metals has been known for a long time without a proper understanding of the mechanism of codeposition. Hints were made by several authors, concerning primarily a ...
Međusobna zavisnost uslova sinterovanja, mikrostrukture i magnetnih svojstava sinterovanih SmCo5 magneta
(Savez inženjera metalurgije Srbije, 1999)
Razmatran je uticaj procesnih promenljivih na mikrostrukturu i magnetna svojstva sinterovanih SmCo5 magneta. Neposredan uticaj mikrostrukture na magnetna svojstva sinterovanih uzoraka omogućava sagledavanje procesa dobijanja ...
Some thermal and electronic transport properties of mineral marmatite (ZnS:Fe)
(Elsevier, 1999)
The thermal diffusivity and some electronic transport properties of semiconducting ore mineral marmatite (ZnS:Fe) from the Trepča mine (Yugoslavia) were determined using a photoacoustic method with a transmission detection ...
Dismutacija azot oksida (NO) kompleksima gvožđa i aminokiselina
(Belgrade : Serbian Chemical Society, 1999)
Reakcije NO sa prelaznim metalima čine osnovu za dejsvo NO u biološkim sistemima.
Reakcije NO sa proteinima koji sadrže hem intenzivno su izučavane. Medjutim, reakcije NO sa drugim metalnim centrima koji se nalaze u ...
Silicon UV flame detector utilizing photonic crystal
(Society of Photo-Optical Instrumentation Engineers, 1999)
Abstract
In this paper we propose a silicon UV flame detector for combustion systems. In gas burners the relative intensity of flame radiation is dominant in the ultraviolet region (below 0.35 μm). In the visible and ...
