Ve dnech 24. a\u017e 29. \u010dervence 2022 se ve francouzsk\u00e9m Lyonu konala mezin\u00e1rodn\u00ed konference \u201eSolgel 2022\u201c, kter\u00e9 se z\u00fa\u010dastnilo tak\u00e9 \u0161est chemik\u016f z katedry chemie P\u0159F OU pod veden\u00edm V\u00e1clava Slov\u00e1ka.<\/p>\n\n\n\n

Organizace Sol-gel konference se zhostila Univerzita Claude Bernard Lyon I a Univerzita Lyon ve spolupr\u00e1ci s International Sol-Gel Society. Konference spojila ty nejlep\u0161\u00ed odborn\u00edky v oblastech (nano)materi\u00e1l\u016f, anorganick\u00fdch l\u00e1tek, hybrid\u016f a polymer\u016f, a stala se tak m\u00edstem, kde se smyly hranice mezi akademickou a pr\u016fmyslovou sf\u00e9rou a kde se prob\u00edraly v\u0161echny aspekty (nano)materi\u00e1l\u016f od jejich z\u00e1klad\u016f a\u017e po aplikace, a to v srdci samotn\u00e9ho Frech Chemistry Valley. Konference poskytla na\u0161im chemik\u016fm vynikaj\u00edc\u00ed p\u0159\u00edle\u017eitost prezentovat sv\u016fj v\u00fdzkum a nav\u00e1zat nov\u00e9 spolupr\u00e1ce s ostatn\u00edmi \u00fa\u010dastn\u00edky ze v\u0161ech kout\u016f sv\u011bta.<\/p>\n\n\n\n

Na\u0161i chemici prezentovali r\u016fznorod\u011b zam\u011b\u0159en\u00fd v\u00fdzkum, od z\u00e1kladn\u00edch studi\u00ed a\u017e po aplikace p\u0159ipravovan\u00fdch materi\u00e1l\u016f. V\u00e1clav Slov\u00e1k p\u0159edstavil v\u00fdsledky sledov\u00e1n\u00ed kinetiky kondenzace resorcinol-formaldehydu r\u016fzn\u00fdmi technikami (FTIR, NMR relaxometri\u00ed a DSC), je\u017e pootv\u00edraj\u00ed pomysln\u00e9 dve\u0159e odhadu teplotn\u00ed funkce a modelov\u00e1n\u00ed kinetiky sledovan\u00e9ho procesu. \u00dapln\u011b poprv\u00e9 byl pomoc\u00ed DSC detekov\u00e1n skeln\u00fd p\u0159echod p\u0159i sol-gel polykondenzaci resorcinolu s formaldehydem, co\u017e prok\u00e1zala a prezentovala Eva Kinnertov\u00e1. Resorcinol-formaldehydov\u00e9 (RF) polymery se velmi \u010dasto pou\u017e\u00edvaj\u00ed pro p\u0159\u00edpravu por\u00e9zn\u00edch uhl\u00edk\u016f p\u0159ev\u00e1\u017en\u011b v monolitick\u00e9 form\u011b, a proto je zapot\u0159eb\u00ed pochopit alespo\u0148 z\u00e1klady jejich reak\u010dn\u00ed kinetiky pro \u00fapravu kone\u010dn\u00fdch vlastnost\u00ed por\u00e9zn\u00edch uhl\u00edk\u016f podle pot\u0159eb jejich zam\u00fd\u0161len\u00e9 aplikace (katal\u00fdza, adsorpce \u010di skladov\u00e1n\u00ed energie). Mezoporozita je v uhl\u00edkat\u00fdch monolitech \u017e\u00e1douc\u00ed zejm\u00e9na pro minimalizaci dif\u00fazn\u00edch omezen\u00ed a lze ji modifikovat volbou r\u016fzn\u00fdch parametr\u016f sol-gel synt\u00e9zy, co\u017e ve sv\u00e9 pr\u00e1ci uk\u00e1zala doktorandka Lucie Ko\u0159en\u00e1. Pro sledov\u00e1n\u00ed mezoporozity pr\u00e1v\u011b takov\u00fdch uhl\u00edkat\u00fdch monolit\u016f je mo\u017eno vyu\u017e\u00edt pom\u011brn\u011b novou a rychlou charakteriza\u010dn\u00ed techniku zvanou termoporometrie. T\u00edm, jak slibn\u00e1 je termoporometrie pro charakterizaci porozity uhl\u00edkat\u00fdch materi\u00e1l\u016f, pota\u017emo z\u00e1klady a v\u00fdzvami spojen\u00fdmi s aplikac\u00ed t\u00e9to techniky, se zab\u00fdvala Gabriela Zelenkov\u00e1. Jinou, l\u00e9pe zavedenou metodou pro charakterizaci porozity (nejen) uhl\u00edkat\u00fdch materi\u00e1l\u016f je fyzisorpce plynu. Na n\u011bkter\u00e9 artefakty a dezinterpretace v\u00fdsledk\u016f v souvislosti s touto technikou pouk\u00e1zal Tom\u00e1\u0161 Zelenka. Por\u00e9zn\u00ed uhl\u00edky p\u0159ipraven\u00e9 z p\u0159\u00edrodn\u00edch zdroj\u016f, jako\u017eto alternativa por\u00e9zn\u00edch uhl\u00edk\u016f p\u0159ipraven\u00fdch z RF polymer\u016f, jsou v sou\u010dasn\u00e9 dob\u011b velmi \u017e\u00e1dan\u00e9. V t\u00e9to souvislosti se Madhav P. Chavhan zab\u00fdval uhl\u00edkov\u00fdmi monolity na b\u00e1zi celul\u00f3zy se zvl\u00e1\u0161tn\u00edm zam\u011b\u0159en\u00edm na uhl\u00edk dopovan\u00fd kovy (nap\u0159. Cu, Mn a Fe) pro elektrochemick\u00e9 aplikace, konkr\u00e9tn\u011b pro skladov\u00e1n\u00ed energie.<\/p>\n\n\n\n

Konference v\u0161ak nebyla jen o p\u0159edn\u00e1\u0161k\u00e1ch, posterech, diskuz\u00edch, vym\u011b\u0148ov\u00e1n\u00ed n\u00e1pad\u016f a zku\u0161enost\u00ed a navazov\u00e1n\u00ed spoluprac\u00ed s dal\u0161\u00edmi v\u00fdzkumn\u00edky. Krom\u011b toho na\u0161i chemici nav\u0161t\u00edvili historick\u00e9 centrum Lyonu s prohl\u00eddkou pam\u00e1tek a neodolali ani l\u00e1kadl\u016fm zdej\u0161\u00ed gastronomie.
