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 ...
Phase-structure analysis of brass by anodic linear-sweep voltammetry
(Springer, 1992)
Anodic linear-sweep voltammetry (ALSV) was applied to electrodeposited alloy layers and to metallurgically obtained Cu−Zn alloys of different composition and structure. Metallurgically obtained samples covered the range ...
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 ...
Investigation of phase-transformation kinetics in electrodeposited Cu + Cd alloys using anodic linear sweep voltammetry
(Elsevier, 1993)
The anodic linear sweep voltammetry technique was used for a quantitative assessment of the phase composition of Cu + Cd alloys obtained by electrochemical deposition. Current peaks obtained in the voltammograms were ...
One dimensional Si-SiO2 photonic crystal with defects intended for use in infrared spectral region
(Institute of Electrical and Electronics Engineers (IEEE), 1997)
Abstract
Based on our detailed theoretical analysis we fabricated 1D Si/SiO2 photonic crystals with donor and acceptor defects. We observed their photonic band-gaps and defect modes by measuring the infrared transmission ...
Opening of the Macrocyclic Ring in 5,10:8,9‐Disecosteroids ( = Steroklastanes)
(Weinheim : Wiley-VCH Verlag GmbH & Co., 1992)
Catalytic hydrogenation of the Δ3‐unsaturated (9R,10 R)‐ and (9S,10 S)‐epoxyenol lactones 3a, b., and 4a, b., respectively, affords, in addition to the expected saturated epoxylactones 5a, b and 7a, b, also open‐chain ...
Synthesis, structure, and reactivity of secosteroids containing a medium‐sized ring. Part 32. Conformations and photochemical reactivity of some unsaturated 5,10‐secosteroidal ketones
(Wiley - VCH Verlag GmbH & Co, 1991)
UV irradiation of the unsaturated (E)‐5,10‐secosteroidal ketones 1 and 6 results, in addition to (E/Z)‐isomerization, in an intramolecular Pateino‐Büchi reaction and, in the case of 1, in transannular cyclization (along ...
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 ...
Kristalografski podaci za srbijanit, novi borni mineral iz Ibarske doline / Crystallographic data for srbianite, new boron mineral from Ibar Valley, Serbia, Yugoslavia
(Belgrade : Serbian Crystallographic Society, 1993)
Сидеритични прослојци у понту околине Неготина
(Geoinstitut, 1993)
Prilikom izdvajanja formacija u neogenu Srbije, duž Save i Dunava (Krstić i dr., 1992) postavilo se pitanje proslojaka sa karbonatom. U vezi sa tim konsultovani su A. Antonović, D.B. Milovanović i druge kolege. Prihvaćena ...
