Particularly, an asymmetric bipolar lipid molecule and an ester thereof respectively represented by general formulae (1) and (2) wherein n is an integer of 18 to 22, both of Z1 and Z2 are single bonds, Y is Gly, m(s) is the same or different integer of 3 to 6, X is OH, and R is a methoxy group, an ethoxy group, or a benzyloxy group are novel substances, and can form a carboxylic acid based asymmetric nanotube by single component self-assembly or binary self-assembly.

In sophisticated semiconductor devices, an asymmetric transistor configuration may be obtained on the basis of a strain-inducing semiconductor alloy. To this end, strain relaxation implantation processes may be performed at the drain side according to some illustrative embodiments, while, in other cases, the deposition of the strain-inducing alloy may be performed in an asymmetric manner with respect to the drain side and the source side of the transistor.

The wear life of flexible copper fiber brushes when used at a positive pole in a direct current motor or generator is improved by the provision of an effective amount of zinc as a sacrificial anode material. Flame-sprayed zinc is applied as a coating to the exterior surface of such a copper fiber pack to bond the fibers with a surrounding metal wire reinforcing wrap, of cross wound copper wire or fine mesh, woven copper wire screen material, and create an improved brush.

A high-voltage electrical connector includes a strategically placed barrier that acts as an arc shield to reduce the ionization of materials during load break switching, reducing or preventing flashover. An electric stress graded interface design also reduces switching flashover and reduces the fault close energy. Mating features on the piston-contact element and inside the surrounding container accurately guide the piston-contact element as it travels along the container.
