Spiders suggest us that producing high strength over density ratio invisible cables could be of great importance. In this letter we show that such invisible cables could in principle be built, thanks to carbon nanotube bundles. Theoretical strength of about 10MPa, Young modulus of about 0.1GPa and density of 0.1Kg per cubic meter are estimated.
In this paper the new concept of super-bridges, i.e. kilometre-long bridges suspended over carbon nanotube cables, is introduced. The analysis shows that the use of realistic (thus defective) carbon nanotube bundles as suspension cables can enlarge the current limit main span by a factor of 3.
Thanks to Victor Veselago for his hypothesis of negative index of refraction, metamaterials -- engineered composites -- can be designed to have properties difficult or impossible to find in nature: they can have both electrical permitivity ($epsilon$
By using an elegant response function theory, which does not require matching of the messy boundary conditions, we investigate the surface plasmon excitations in the multicoaxial cylindrical cables made up of negative-index metamaterials. The multico
Diamond is used extensively as a component in high energy density experiments, but existing equation of state (EOS) models do not capture its observed response to dynamic loading. In particular, in contrast with first principles theoretical EOS model
We report on the theoretical investigation of the plasmonic wave propagation in the coaxial cylindrical cables fabricated of both right-handed medium (RHM) [with $epsilon >0$, $mu >0$] and left-handed medium (LHM) [with $epsilon(omega) <0$, $mu(omega
