11. Resolving the dilemma of Fe-N-C catalysts by the selective synthesis of tetrapyrrolic active sites via an imprinting strategyDavide Menga, Jian Liang Low, Yan-Sheng Li, Iztok Arčon, Burak Koyutürk, Friedrich Wagner, Francisco Ruiz-Zepeda, Miran Gaberšček, Beate Paulus, Tim-Patrick Fellinger, 2021, original scientific article Abstract: Combining the abundance and inexpensiveness of
their constituent elements with their atomic dispersion, atomically
dispersed Fe−N−C catalysts represent the most promising
alternative to precious-metal-based materials in proton exchange
membrane (PEM) fuel cells. Due to the high temperatures
involved in their synthesis and the sensitivity of Fe ions toward
carbothermal reduction, current synthetic methods are intrinsically
limited in type and amount of the desired, catalytically active Fe−
N4 sites, and high active site densities have been out of reach
(dilemma of Fe−N−C catalysts). We herein identify a paradigm
change in the synthesis of Fe−N−C catalysts arising from the
developments of other M−N−C single-atom catalysts. Supported
by DFT calculations we propose fundamental principles for the synthesis of M−N−C materials. We further exploit the proposed
principles in a novel synthetic strategy to surpass the dilemma of Fe−N−C catalysts. The selective formation of tetrapyrrolic Zn−N4
sites in a tailor-made Zn−N−C material is utilized as an active-site imprint for the preparation of a corresponding Fe−N−C catalyst.
By successive low- and high-temperature ion exchange reactions, we obtain a phase-pure Fe−N−C catalyst, with a high loading of
atomically dispersed Fe (>3 wt %). Moreover, the catalyst is entirely composed of tetrapyrrolic Fe−N4 sites. The density of
tetrapyrrolic Fe−N4 sites is more than six times as high as for previously reported tetrapyrrolic single-site Fe−N−C fuel cell catalysts

19. Bivališča Branislave Sušnik : dokumenti, besedila, podobe, pričevanjaBarbara Pregelj, Francisco Tomsich, scientific monograph Abstract: Antropologinja, arheologinja in jezikoslovka Branislava Sušnik (Medvode, Slovenija, 1920 ̶ Asunción, Paraguay, 1996) je eno od najpomembnejših imen intelektualne panorame sodobnega Paragvaja. Njene raziskave s področja zgodovine, jezikov in kultur številnih staroselskih ljudstev z juga Južne Amerike pa tudi njena razmišljanja o paragvajski identiteti sestavljajo enciklopedično in subverzivno panoramo, ki jo je šele treba odkriti. Njena življenjska pot je bila zapletena, njeni življenjepisi so polni protislovij in skrivnosti.
Ta v celoti dvojezična knjiga, prva monografija o njenem življenju in delu v slovenščini, prinaša rezultate interdisciplinarne raziskave, ki je potekala v različnih smereh in pri kateri so sodelovali pisatelji, raziskovalci in umetniki iz Paragvaja in Slovenije. Monografija prinaša še večinoma neobjavljene dokumente, besedila, podobe in pričevanja, ki skušajo vsaj deloma osvetliti življenje Branislave Sušnik, preizprašujejo njeno dediščino ter odpirajo nove možnosti prebiranja in udejanjanja njenega dela tako v Sloveniji kot v Paragvaju.
ZNANSTVENA MONOGRAFIJA (ne morem dodati pri tipologiji)!
