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 ...
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. ...
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.
Interaction of nanoparticles with ideal liquid-liquid interfaces
Using molecular simulations the interaction between a noncharged nanoparticle and an ideal liquid-liquid interface is studied. The free energy profile as function of nanoparticle-interface separation is determined using ...
Onde de Love Piézoacoustique
Une sélection de résultats analytiques et numériques concernant la propagation d'ondes planes harmoniques guidées dans un bicouche piézoélectrique est présentée. L'étude effectuée concerne les modes transverses horizontaux ...
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 ...
Syntheses of C-substituted icosahedral dicarbaboranes bearing the 8-dioxane-cobalt bisdicarbollide moiety
The treatment of 1,2-, 1,7- and 1,12-carbaborane lithiated isomers with [3,3′-Co-8-(CH2CH2O)2-(1,2-C2B9H10)-(1′,2′-C2B9H11)] (1) at molar ratios 1:1 or 1:2 at room temperature in THF leads generally to the formation of a ...
Classification of narcotics in solid mixtures using principal component analysis and Raman spectroscopy
(ASTM International, 2002-03-01)
Eighty-five solid samples consisting of illegal narcotics diluted with several different materials were analyzed by near-infrared (785 nm excitation) Raman spectroscopy. Principal Component Analysis (PCA) was employed to ...
Fluorescence lifetime based pH sensing using Resorufin
Accurate, non-contact pH sensing is of particular importance in the biological and clinical sciences. Fluorescence lifetime based pH sensing is potentially more useful than intensity based methods because of the reduced ...
