41.   Belgrade and nine other cities were dark early Saturday as NATO jets dropped carbon bombs, short-circuiting wires that conduct electricity, Yugoslav media reported.

42.   Earlier studies showed that nanotubes can conduct electricity and that the tubes are able to slip back and forth within each other will little friction.

43.   Earlier this month, the alliance started using the special cluster bombs that disperse carbon filaments across wires that conduct electricity, short-circuiting the transformers.

44.   Fullerenes have no practical application yet, but researchers are working on using them to conduct electricity without resistance or to deliver medicine into the body.

45.   In different forms they can conduct electricity like a metal or can be semiconducting.

46.   Last year, the Nobel Prize for chemistry was awarded to researchers who originally demonstrated that plastics can conduct electricity.

47.   Such fluids contain no salt, which is essential to the body but conducts electricity.

48.   Tests showed that it conducted electricity with about the same ability as a plain sample of magnesium diboride.

49.   The NATO weapons also included special cluster bombs with carbon filaments that cause damage to wires conducting electricity, the media said.

50.   The scientists were rewarded for their revolutionary discovery that plastics can, with modifications, be made to conduct electricity as well as insulate.
