Platinum group metals (PGMs) serve as highly active catalysts in a variety of heterogeneous chemical processes. Unfortunately, their high activity is accompanied by a high affinity for CO and thus, PGMs are susceptible to poisoning. Alloying PGMs with metals exhibiting lower affinity to CO could be an effective strategy toward preventing such poisoning. In this work, we use density functional t...

This paper contributes to theorizing about issues of pedagogy through elaborations on the idea of design experimentation as a methodological and analytical tool within the culturalhistorical activity theory (CHAT) perspective. Our aim is to show that whereas it is analytically possible to separate people and implementations of pedagogical procedures from what are referred to as 'contexts' and '...

Cognition is no longer confined to the solitary musings of an armchair philosopher, but takes place, for instance, in problem-solving efforts of teams of people distributed around the world and involving various artifacts. The study of such cognition can unfold at multiple units of analysis. Here, three cases of problem solving by virtual math teams demonstrate the mix of individual, group and ...

Abstract AI technologies hold great promise for addressing existing problems in organizational contexts, but the potential benefits must not obscure perils associated with AI. In this article, we conceptually explore these promises and by examining use contexts. The exploration complements extends extant literature on management providing a typology describing four types of use, based idea co-c...
