Sustainable One‐Pot Synthesis of N‐Substituted Pyrroles Using a Multifunctional Cobalt‐Based Catalyst

ChemCatChem, EarlyView.
The one‐pot synthesis of N‐substituted pyrroles from nitrobenzene and 2,5‐hexanodione is first ever reported with >99% conversion and >99% chemoselectivity, in a green solvent, using a non‐noble metal‐based catalyst and hydrogen as a reductant under mild reaction conditions simultaneously.

Electrostatic Attraction‐Driven Assembly of Non‐Noble Metallo‐Supramolecular Polymers With Single‐Walled Carbon Nanotubes for Boosting Photocatalytic Hydrogen Evolution

Carbon Energy, EarlyView.
Two cationic non‐noble metallo‐supramolecular polymers Se‐MTpy (M = Co or Ni) and their composites with anionic CNTs via electrostatic attraction and π–π interactions have been prepared for efficient and stable photocatalytic hydrogen evolution. The constructive formation of junctions between polymer and CNTs facilitates interfacial charge transfer and

What Types of Knowledge‐Intensive Business Services Use Services as a Source of Innovation?

Canadian Journal of Administrative Sciences / Revue Canadienne des Sciences de l'Administration, EarlyView.
ABSTRACT The paper examines the factors that influence why knowledge‐intensive business services (KIBS) draw from other KIBS firms in their innovation activities. We provide new empirical evidence on specific firm‐level conditions under which the interactions between KIBS–KIBS are more (or less) likely to be observed. The effects of internal resources,
