      A series of clusters of the form [Et4N][Fe2(CO)6(μ3-As)}(μ3-EFe(CO)4)], where E is either P or As, were synthesized from [Et4N]2[HAs{Fe(CO)4}3] and ECl3. AsCl3 gives the As-only compound; PCl3 produces compounds having two ...
    • New Model for Understanding Mechanisms of Biological Signaling: Direct Transport via Cytonemes 

      Teimouri, Hamid; Kolomeisky, Anatoly B. (2016)
      Biological signaling is a crucial natural process that governs the formation of all multicellular organisms. It relies on efficient and fast transfer of information between different cells and tissues. It has been presumed ...
