style='font-size:12.0pt;line-height:115%;font-family:"Times New Roman","serif"'>Pred dvajsetimi leti povezave besed "kemija" in "materiali" ni bilo. Kemijska znanost je bila tradicionalno razdeljena v organsko, anorgansko in fizikalno kemijo. Vzporedno je fizika trdne snovi takrat v glavnem obravnavala primere preprosto urejenih kristalnih struktur s ciljem, da bi razumela modelne elektronske strukture: ionske (NaCl, MgO), kovalentne (C, Si), kovinske (Na, Cu), Van der Waalsove (organske spojine, žlahtni plini) in druge. Po letu 1970 pa je postalo jasno, da tak poenostavljen način ne zadošča več. Na primer: dejstva, da so molekulske trdne snovi lahko kovine ali celo superprevodniki, da so nizko dimenzionalne trdne snovi lahko ionske v eni orientaciji ali kovinske oziroma magnetne v drugi in da so feromagneti lahko transparentni, izolacijski in celo topni v topilih, se s takratnimi modeli ni dalo razložiti. Ob tem so se pojavile nove oblike snovi z novimi fizikalnimi lastnostmi: molekulski magneti, kiralni magneti, prevodniki in drugo. Nova spoznanja izhajajo iz načina kemijske sinteze – od tod torej izvira ime »kemija materialov«. V predavanju bo predstavljena transformacija znanosti o trdni snovi s primeri raziskav predavatelja, hkrati pa bo govor tudi o prihodnjem razvoju, ko naj bi nastajale nove strukture in lastnosti, ki so danes znane zgolj teoretično.<o:p></o:p></span></pre>

lang=EN-US>Twenty years ago the two words ‘materials’ and
‘chemistry’ were never found together. Traditionally the science
of chemistry was divided into organic (dealing with carbon-containing
molecules), inorganic (the broad palette of the Periodic Table, but subdivided
into molecular and continuous-lattice solid-state) and physical (aiming to
define the fundamental principles that would unify the whole subject). In
parallel, solid-state physics treated mainly paradigms taken from the simplest
ordered crystal structures to probe the limits of the extreme models of
electronic structure: ionic (NaCl, MgO), covalent (C, Si,), metallic (Na, Cu),
Van der Waals (organics and rare gases) and so on. From the 1970s onwards it
became clear that such a simplistic approach was breaking down. For example,
molecular solids can be metals or even superconductors; low-dimensional solids
may be ionic in one orientation but metallic or magnetic in another;
ferromagnets may be transparent, insulating and even solvent-soluble. Added to
this, new forms of matter with new kinds of physical properties have emerged:
single-molecule-magnets, chiral magnets and conductors and so on. This novelty
arises from chemical synthesis – hence the emergence of ‘materials
chemistry’. In this lecture I will survey this transformation in
condensed-matter science, in part using examples from our own work, and also
look forward towards structures and properties that don’t exist now but
may be capable of doing so in the future.</span><span lang=EN-US
