A method of preparing a solid material based on tangled nanotubes andor nanofibres, includes a step of growing carbon nanofibres andor nanotubes with restraint in a contained reactor; and the materials thus obtained. A fast reverse restore command indicating a new source and a new target is received, wherein the new source is an original target and the new target is an original source. The suction side of the wafer chuck is provided with a first area in which the pin-shaped protrusions are arrayed in a grid-line manner, and a second area in which the pin-shaped protrusions are arrayed in circumferential form. Similarly, R2 comprises the sequence X\u20323X\u20324X\u20325GPX\u20326TX\u20327X\u20328X\u20329 wherein X\u20323 is C or Hoc, X\u20324 is R, H, L or W, X\u20325 is M, F, I or J, X\u20326 is any one of the 20 genetically coded L-amino acids or J, X\u20327 is W, B or U, X8\u2032 is D, E, I, L or V, and X\u20329 is C or Hoc.
