Designs of new forms of matter composed of nucleons (neutrons, protons), electrons, and other nuclear particles are detailed. This matter is measured in the femtometer (10 -15 m) scale (―femtotechnology‖), which is millions of times smaller than material on the nanometer (10 -9 m) scale (―nanotechnology‖). These new femto-needles, femto-tubes have extraordinary properties such as tensile streng...
