An outstanding compression function for materials preparation exhibited by nanospaces of single-walled carbon nanohorns (SWCNHs) was studied using the B1-to-B2 solid phase transition KI crystals at 1.9 GPa. High-resolution transmission electron microscopy and synchrotron X-ray diffraction examinations provided evidence that nanocrystals doped in nanotube spaces SWCNHs pressures below 0.1 MPa had super-high-pressure B2 structure, which is induced above GPa bulk crystals. This finding supercompression nanotubular can lead to development a new compression-free route precious whose syntheses require application high pressure.
