during 1983 and 1984 as part of the noaa agasp program, the first measurements of such distributions in the arctic atmosphere were obtained with an aethalometer which had the capability of measuring black carbon on a real-time basis. these measurements showed substantial concentrations of black carbon found throughout the western arctic troposphere including the north pole. the vertical profiles showed either a strongly layered structure or an almost uniform distribution up to eight kilometers with concentrations within layers as large as those found at ground level in typical mid-latitude urban areas in the united states. the absorption optical depths associated with these vertical profiles were large as evidenced by a vertical profile over the norwegian arctic where absorption optical depths of 0.023 to 0.052 were calculated respectively for external and internal mixtures of black carbon with the other aerosol components.

silicyne









































silicynes are allotropes of silicon.









































1-dimensional silicyne is analogous to the carbon allotrope carbyne, being a long chain of silicons, instead of carbons. it is amorphous silicon with "sp" hybridization of the valence electrons. silicyne is a single linear molecule composed of just silicon atoms. one of the manners they are bonded to each other in a succession of double-bonded silicons, analogous to the situation of carbon found in cumulene. the other manner they may be bonded to each other is a succession of alternating single and triple-bonded silicons, analogous to the situation of carbon found in polyyne.
