2. Beyond Knower Levels: Early partial knowledge of number wordsDavid Barner, Rok Žaucer, Jessica Sullivan, Tina Razboršek, Vesna Plesničar, Katie Wagner, Franc Marušič, 2015, published scientific conference contribution abstract Abstract: Although both syntax and number words can indicate quantity, only numbers can specify large exact quantities. Do children use
syntax to bootstrap preliminary meanings of number words before mastering precise meanings? We compared errors across
languages on a Give-a-Number task in non-knowers (who have adult meanings for no number words) and subset knowers (who
have adult meanings for fewer than five number words). Participants included learners of English, Spanish, French, and two
dialects of Slovenian. One dialect, Central Slovenian, has rich number morphology including singular, dual, small plural, and large
plural (for 5+). In all languages, subset knowers and some non-knowers demonstrated better than random responding for at least 2
number words beyond the largest number word they comprehended precisely. Additionally, Central Slovenian-learning non- and 1-
knowers responded more accurately to requests for higher numbers than their counterparts in other languages, suggesting that rich
plural marking may bootstrap number word meanings.

3. Resolving the dilemma of Fe-N-C catalysts by the selective synthesis of tetrapyrrolic active sites via an imprinting strategyTim-Patrick Fellinger, Beate Paulus, Miran Gaberšček, Francisco Ruiz-Zepeda, Friedrich Wagner, Burak Koyutürk, Iztok Arčon, Yan-Sheng Li, Jian Liang Low, Davide Menga, 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
