Mechanical Properties of Polyethylene-Carbon Nanotube Composites Synthesized by In Situ Polymerization Using Metallocene Catalysts

open access: yesAdvances in Materials Science and Engineering, 2018
The influence of multiwalled carbon nanotubes (MWCNTs) on the properties of polyethylene prepared by in situ polymerization using metallocene catalyst (Cp2ZrCl2) in combination with methylaluminoxane has been studied.

Propylene Polymerization Catalyzed by Metallocene/Methylaluminoxane Systems on Rice Husk Ash

open access: yesMolecules, 2019
Silica generated from agricultural waste is more cost effective and environmentally friendly than silica from traditional commercial processes. In this study, spherical silica particles with a diameter of around 120 nm were fabricated from rice husk ash (

Hybrid materials based on polyethylene and MCM-41 microparticles functionalized with silanes: catalytic aspects of in situ polymerization, crystalline features and mechanical properties [PDF]

open access: yes, 2016
New nanocomposites based on polyethylene have been prepared by in situ polymerization of ethylene in presence of mesoporous MCM-41. The polymerization reactions were performed using a zirconocene catalyst either under homogenous conditions or supported

Group 10 and Group 11 Metal Complexes of a Thermally Stable N‐Heterocyclic Carbene with a 1,1′‐Ferrocenylene Backbone

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 15, October 21, 2025.
The ferrocene‐based, and hence redox‐functionalized, N‐heterocyclic carbene fc[N(CH2Mes)]2C (A; fc = 1,1′‐ferrocenylene, Mes = mesityl) provides access to group 10 (trans‐[MCl2(A)2], M = Ni, Pd) and group 11 metal complexes ([MCl(A)], M = Cu, Ag, Au; ([CuX(A)], X = Br, I, Mes; [Cu(A)2][BF4]).

Dibora[2]ferrocenophane: a carbene-stabilized diborene in a strained cis-configuration [PDF]

open access: yes, 2016
Unsaturated bridges that link the two cyclopentadienyl ligands together in strained ansa metallocenes are rare and limited to carbon-carbon double bonds. The synthesis and isolation of a strained ferrocenophane containing an unsaturated two-boron bridge,

Harvesting and Electron-Exchange Energy Transfer by d0 Metallocene-based Organized Systems [PDF]

open access: yes, 2013
The present contribution will provide an up-to-date overview of novel experimental and theoretical (de-rived quantum-chemically) knowledge on photonics of group IV metallocene-based systems, also with re-spect to their prominent use in catalysis and ...
