	Mineralization of [14C] octadecane by Acinetobacter calcoaceticus S19 (Site not responding. Last check: 2007-10-08)
		Uptake of octadecane by Acinetobacter calcoaceticits S 19 was found to be 70% during growth (doubling time of 4 h), of which 60% was incorporated into the cells and 40% was oxidized to
		C]octadecane uptake to its mineralization by whole cells was similar to that found during the growth of A. calcoaceticus S 19.
		Octadecane uptake was not observed under anaerobic conditions, indicating an absolute requirement for oxygen.

	Results
		Results for Octadecane Spheres in PDMS are shown here.
		Octadecane in this sample is embedded in PDMS resin, which has a very low thermal conductivity, as described in the materials selection page.
		In this sample, the octadecane powder was evenly distributed throughout the PDMS resin and there was no flaking away of the octadecane from the resin when the sample was cut.

	Team 2: Processing/Procedures
		A different procedure was used for the octadecane and the paraffin because the procedure used for the paraffin was both extremely time consuming and lost a significant amount of material.
		Because the octadecane microspheres appeared to have melted and recrystallized during processing, it was decided to cool the solution the next time.
		Octadecane was crushed with a mortar and pestal (shown in diagram) for several minutes.

	Thermal storage/release, durability, and temperature sensing properties of thermostatic fabrics treated with ... (Site not responding. Last check: 2007-10-08)
		The cooling effect from thermal storage of the octadecane-containing microcapsules is revealed by results showing that the changes in the mean skin and microclimate temperature with the treated garment are less than for those wearing the untreated garment.
		Octadecane is a kind of phase change material (PCM) that is able to absorb, store, and release large amounts of latent heat over a defined temperature range when the material changes phase or state [5].
		In the slushy state, octadecane acts like a thermostatic substance that causes the liquid portion to release heat and helps to prevent the temperature next to the skin from cooling.

		These are the forces that hold a solution of pentane molecules together, or a solid of octadecane molecules together.
		per unit length of the molecule are nearly identical for two interacting propanes or two interacting pentanes, or two interacting octadecanes.
		Thus, a solution of octadecane is held together more strongly than is a solution of pentane than is a solution of propane.

		They store 5 to 14 times more heat per unit volume than conventional storage materials such as water, masonry, or rock.
		The most commonly used PCMs are salt hydrides, fatty acids and esters, and various paraffins (such as octadecane).
		Recently also ionic liquids were investigated as novel PCMs.
