Doktorant naszego Instytutu Rafa\u0142 Juroszek oraz pracownicy dr hab. Irina Galuskina prof. U\u015a i prof. dr hab. Evgeny Galuskin opublikowali w marcowym numerze czasopisma American Mineralogist artyku\u0142 na temat nowego minera\u0142u \u2013 siwaqaitu, kt\u00f3ry zosta\u0142 odkryty w pustkach w obr\u0119bie marmur\u00f3w spurrytowych kompleksu Hatrurim na terytorium Jordanii. Minera\u0142 ten zosta\u0142 zatwierdzony w 2019 roku przez Komisj\u0119 Nowych Minera\u0142\u00f3w, Nomenklatury i Klasyfikacji przy Mi\u0119dzynarodowej Asocjacji Mineralogicznej. Siwaqaite, maj\u0105cy wz\u00f3r Ca6<\/sub>Al2<\/sub>(CrO4<\/sub>)3<\/sub>(OH)12<\/sub>\u00b726H2<\/sub>O, jest unikatowym minera\u0142em grupy ettryngitu, w kt\u00f3rym chrom (Cr6+<\/sup>) tworzy grup\u0119 chromianow\u0105 (CrO4<\/sub>)2-<\/sup>. Ten nowy minera\u0142 mo\u017ce odegra\u0107 rol\u0119 prototypu do stworzenia materia\u0142\u00f3w do przechwytywania bardzo niebezpiecznych w \u015brodowisku zwi\u0105zk\u00f3w (Cr6+<\/sup>).<\/p>\n<\/div>\r\n <\/div>\r\n <\/div>[\/vc_column][vc_column width=”1\/2″][vc_single_image image=”2684″ img_size=”full” add_caption=”yes”][vc_single_image image=”2685″ img_size=”full” add_caption=”yes”][\/vc_column][\/vc_row]<\/p>","protected":false},"excerpt":{"rendered":"
