face="Times New Roman" size=3>Ogljik je edinstven kemijski element z izredno
bogato raznolikostjo alotropnih struktur. Tako na primer diamant in grafit
posedujeta vrsto izjemnih fizikalnih in kemijskih lastnosti, ki so se v
dvajsetem stoletju temeljito raziskale in tudi izkoristile v različnih
aplikacijah. Odkritje fulerenov (1985) in nanocevk (1991) predstavlja neke vrste
prelomnico v raziskavah ogljikovih struktur. V zapletenem svetu kristalnih
defektov lahko podobne topološke prijeme uporabimo na grafitnih plasteh, ki jih
zvijemo, prelomimo ali pa “zvarimo” v nove strukture. Opis tovrstnih defektov
izhaja iz fizike dislokacij in njihove strukture lahko napovemo z uporabo DFT
teorije. Identifikacija in karakterizacija dislokacij v grafitu nam odstre
pogled v svet struktur, ki so bile poprej spregledane pri raziskavah grafita in
še posebej v strukture, ki nastanejo pri obsevanju z visoko energijskimi
nevtroni v reaktorjih.</FONT></P>

face="Times New Roman">Carbon is an element that is unique in the variety,
utility and individuality of its allotropes. Diamond and graphite each have
several uniquely extreme properties that have been exploited in twentieth
century science and technology. Against the curious landscape of the periodic
table the discoveries of fullerenes (1985) and nanotubes (1991) stand out as
substantial landmarks. Their beauty lies in creating isolatable molecular forms.
In the somewhat messier world of crystal defects, similar topological concepts
can be applied, leading to sheets which are buckled, folded, ‘welded’ together,
or unified into one sheet. The description of these defects comes from the
science of dislocations, and their structures can be deduced from first
principles methods, such as density functional theory (DFT). A connector between
sheets, similar to the ramp connecting the floors of a multistorey car park, is
a prismatic screw dislocation dipole. A fold is a pile-up of basal dislocation
dipoles. The identification and characterization of dislocations in graphite,
gives insight into structures which have been overlooked in the science of
graphite, especially radiation damage which occurs in reactor graphite subjected
to energetic neutrons.<o:p></o:p></FONT></FONT></SPAN></P>
