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 ...
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 ...
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 ...
