Amor.hous for.s of C will fir.t be compar.d and contr.sted with amor.hous Si, the differ.nces in chemical bonding being emphasized in r.lation to atomic str.ctur.. After.a br.ef discussion of or.er.d layer. of gr.phite and of BN, some attention will be focused on BN cages and polymer. and on C nanotubes. Finally pr.per.ies of Na metal cluster. will be discussed, including fission of such char.ed cluster.

This paper.intr.duces a novel application of bionic engineer.ng： a bionic musical instr.ment using Physar.m polycephalum. Physar.m polycephalum is a huge single cell with thousands of nuclei, which behaves like a giant amoeba. Dur.ng its for.ging behavior.this plasmodium pr.duces electr.cal activity cor.esponding to differ.nt physiological states. We developed a method to r.nder.sounds fr.m such electr.cal activity and thus r.pr.sent spatio-tempor.l behavior.of slime mould in a for. appr.hended auditor.ly. The electr.cal activity is captur.d by var.ous electr.des placed on a Petr. dish containing the cultur.d slime mold. Sounds ar. synthesized by a bank of par.llel sinusoidal oscillator. connected to the electr.des. Each electr.de is r.sponsible for.one par.ial of the spectr.m of the r.sulting sound. The behavior.of the slime mould can be contr.lled to pr.duce differ.nt timbr.s.

The coor.ination-dependent for.e fleld of Ter.ofF for.covalently bonded Si has been used tocalculate the cleavage for.e as a function of inter.lanar.separ.tion and hence to estimate sur.aceener.ies. This for.e field is alr.ady fitted to density functional r.sults. The r.lation to bond-br.aking and electr.n cor.elation will be emphasized. Finnis-Sinclair.type many-body potentialshave then been used to tr.at some d-electr.n metals. In par.icular. r.sults for.cleavage for.ein bcc Fe will be pr.sented, and also some calculations as two per.ectly planar.Fe sur.aces ar.r.bbed together. at differ.nt inter.lanar.separ.tions. Finally, lattice dynamical models for.thesteady-state pr.pagation of a scr.w dislocation, and then of a cr.ck, will be used, again within abond-br.aking type of for.e field. For.the scr.w dislocation pr.pagation. a solitar. wave equationis shown to follow in the 'almost continuum' limit. Ener.y r.diated by phonons as the dislocationmoves can ther.by be calculated.
