An algorithm for the unit group of the Burnside ring of a finite group
(Cambridge University Press, 2007-01)
In this note we present an algorithm for the construction of the unit group of the Burnside ring Ω(G) of a finite group G from a list of representatives of the conjugacy classes of subgroups of G.
Molecular structure and phase behaviour of hairy-rod polymers
(Royal Society of Chemistry, 2009)
Using dissipative particle dynamics simulations the relationship between molecular architecture and phase behaviour in model hairy-rod polymers is studied. In agreement with experimental and theoretical studies the phase ...
Liquid-crystal-mediated force between a cylindrical nanoparticle and substrate
(American Physical Society, 2007-10-25)
Using classical density functional theory, the structure of a molecular fluid around a cylindrical nanoparticle near a solid substrate is studied. The solvent-mediated force between the nanoparticle and the substrate is ...
Role of mitochondria in neuronal apoptosis
(Karger Publishers, 2000-12)
Apoptosis is a controlled form of cell death that participates in the demise of neuronal cells during development, neurodegenerative disorders and exposure to neurotoxic agents. In recent years, the mitochondria have emerged ...
Wireless communicative stent for follow-up of abdominal aortic aneurysm,
An abdominal aortic aneurysm (AAA) is a dilatation of the aorta at the abdominal level, which rupture is a life threatening complication. Recent treatment of AAA consists in endovascular treatment with covered stent grafts. ...
Metallacarboranes as building blocks for polyanionic polyarmed aryl-ether materials
(American Chemical Society, 2008-09-20)
Polyanionic species have been obtained in high yield by a new route in the ring-opening reaction of cyclic oxonium [3,3′-Co(8-C4H8O2-1,2-C2B9H10)(1′,2′-C2B9H11)] (2) by using carboxylic acids, Grignard reagents, and ...
Towards the synthesis of high boron content polyanionic multicluster macromolecules
(American Chemical Society, 2009-07-31)
Reported are further consequences of the dioxane ring-opening in [3,3’-Co(8-(CH2CH2O)2-1,2-C2B9H10)(1’,2’-C2B9H11)]  with twelve-vertex carborane mono- and dianions. The removal of one BH vertex from the 1,2-carborane ...
A discrete P⋅⋅⋅I I⋅⋅⋅P assembly: the large influence of weak interactions on the 31P NMR Spectra of Phosphane–Diiodine Complexes
Seeing I to I: The reaction of a weakly coordinating carboranyl phosphane ligand with I2 leads to the formation of an adduct containing the bridging P⋅⋅⋅I[BOND]I⋅⋅⋅P assembly in the solid state (see picture; I purple, P ...
A convenient synthetic route to useful monobranched polyethoxylated halogen terminated [3,3 -Co(1,2-C2B9H11)2]- synthons
(Royal Society of Chemistry, 2009-11-15)
An atom efficient and environmentally friendly route has been developed to obtain a new range of reagents in metallacarborane chemistry having monobranched polyethoxylated cobaltabisdicarbollide synthons.
Prediction of pK(a) values of nido-carboranes by density functional theory methods
(American Chemical Society, 2006-08-25)
A great parallel exists between metal complexes of cyclopentadienyl and arene ligands on one side and metal complexes of the nido derivatives of the icosahedral o-carborane clusters. With few exceptions, the metal complexation ...
