The present invention relates to a composite material including a substrate with a first and a second layer, and a surfactant. The method includes assigning to each node in the tree list a line structure identifying attributes of the node to be displayed; displaying at least two nodes having different line structures in a display area; and, for each of the at least two nodes, displaying, in the display area, the attributes of the node identified by the assigned line structure. The transfer assembly is capable of moving a workpiece tofrom the first processing location along a second path fromto the nesting assembly. The system of the present invention thus permits one to use different dye sets to tag DNA nucleotides in samples which migrate in separate lanes, and also allows for in-situ calibration with new, previously unused dye sets. Some of the radially outer ends of the straight sections are bent into small half circles that fit into corresponding slots in the nut to fix the resistance ring relative to the nut. An embodiment of the semiconductor devices comprises a vertical transistorcapacitor cell including a nanotube.
