Near‐Armchair‐Enriched Growth of Single‐Walled Carbon Nanotubes via W‐Containing Fe‐Based Catalyst Systems in Mist FC‐CVD

Small, EarlyView.
A mist‐based floating catalyst chemical vapor deposition (mist FC‐CVD) strategy allows the use of non‐volatile precursors and multi‐component catalyst delivery in a continuous process. Through catalyst composition control, it generates near‐armchair‐enriched single‐walled carbon nanotubes (SWCNTs) and uncovers key factors governing chiral‐angle ...

Redox‐Active Bisphosphines Based on a W(II)‐Propargyl Complex Backbone

European Journal of Inorganic Chemistry, Volume 29, Issue 19, 2 July 2026.
Three bisphosphine ligands based on tungsten(II) propargyl‐type alkyne complexes were synthesized and characterized. The methanolate derivative was used as a metalla‐ligand for the preparation of a binuclear bisphosphine‐κ2‐PdCl2 complex. In both cases, IR spectroelectrochemistry (IR‐SEC) measurements revealed a successive process following oxidation ...

28. Molecular Weight Distribution Control with Supported Metallocene Catalysts

, 1994
Several kinds of supported Cp(2)MeCl(2) (Me = Ti, Zr, Ht) catalysts were prepared with three different SiO2-supports; i.e., SiO2/MAO, SiO2/Al(C2H5)(3) and SiO2/(C2H5)MgCl.

Synthesis, Electrochemistry, In Vitro Antiprotozoal Efficacy and Mechanistic Study of Novel ‘Ferrantoin’ and Related Derivatives

Applied Organometallic Chemistry, Volume 40, Issue 7, July 2026.
1,2‐Disubstituted ferrocene analogues bearing hydantoin or rhodanine synthons were synthesised and assessed for antitrypanosomatid activity. An antileishmanial early lead, analogue 23, acting through ROS generation and hence oxidative stress, was uncovered.
