How Circular Innovation Is Learned: A Process Study of Modularity‐Based Initiatives in Industrial Firms

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular innovation (CI) research has identified a wide range of circular strategies and design approaches, yet offers limited insight into how CI evolves as a learning process within firms and which governance mechanisms guide this progression. Drawing on organizational learning (OL), this study examines how exploration and exploitation shape

Uncatalyzed Guanosine Phosphorylation under Potentially Prebiotic Conditions

open access: yesChemistry – A European Journal, EarlyView.
Pyrophosphate acts as phosphorylating agent of guanosine under simple wet‐dry cycles without condensing agent and inorganic catalysts to afford cyclic guanosine monophosphate derivatives useful for oligomerization in prebiotic processes. ABSTRACT The phosphorylation of nucleosides and their subsequent polymerization are key issues in the study of the ...
