Computational and experimental investigations on the effect of crystallinity and crystal size on Na-transport in nanoscaled Si: implications for Si-based anodes for Na-ion batteries

Journal of Solid State Electrochemistry - While Li transport in Si is well understood, little is known about Na transport, despite Si being considered a potential anode material for the upcoming...     

Synthesis of Azaspiro Tricyclic Scaffolds through Post-Ugi Modifications: Scope and Limitation of Aza-Michael Cyclization

Post-Ugi modifications offer a great tool to construct functionalized heterocycles in an atom-economic manner. Using this approach, we have constructed highly functionalized azaspiro tricyclic scaffolds that involve Ugi condensation and ipso-cyclization followed by aza-Michael ring closures. Herein, we present a detailed account of aza-Michael cyclizations with respect to substrate scope and limitations, along with new methods to prepare novel azaspiro tricyclic scaffolds.
