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)] [1] with twelve-vertex carborane mono- and dianions. The removal of one BH vertex from the 1,2-carborane ...
Spherulization as a process for the exudation of chemical cues by the encrusting sponge C. crambe
(Nature Publishing Group, 2016-07-06)
Ecological interactions in the marine environment are now recognized to be partly held by chemical
cues produced by marine organisms. In particular, sponges are sessile animals thought to rely on
the bioactive substances ...
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 ...
Coiled coil type neoglycoproteins presenting three lactose residues
(Elsevier, 2016-02-06)
Scaffold design, synthesis and application are relevant for biomedical research. For example, multivalent interactions, such as those between cell surface glycoproteins and lectins can influence the potency and duration ...
Lewis acid induced anomerization of se-glycosides. Application to synthesis of alpha-Se-GalCer
(American Chemical Society, 2016-01-22)
The TiCl4 induced anomerization of selenium glycosides of galacturonic acid derivatives is reported. The reaction was successful for galacturonic acid when various alkyl, alkenyl, alkynyl, saccharide, steroid, and lipid ...
On the use of 31P NMR for the quantification of hydrosoluble phosphorus-containing compounds in coral host tissues and cultured zooxanthellae
(Nature Publishing Group, 2016-02-23)
31P Nuclear Magnetic Resonance (NMR) was assessed to investigate the phosphorus-containing compounds present in the tissues of the scleractinian coral Stylophora pistillata as well as of cultured zooxanthellae (CZ). Results ...
Phase behaviour of self-assembled monolayers controlled by tuning physisorbed and chemisorbed states: A lattice-model view
(American Institute of Physics, 2016-04-07)
The self-assembly of molecules on surfaces into 2D structures is important for the bottom-up fabrication of functional nanomaterials, and the self-assembledstructure depends on the interplay between molecule-molecule ...
A detailed chemical kinetic modeling, ignition delay time and jet-stirred reactor study of methanol oxidation
(Elsevier, 2016-01-29)
A shock tube (ST) and a rapid compression machine (RCM) have been used to measure new ignition delay times for methanol oxidation over a wide range of pressures (2-50 atm) and equivalence ratios (0.5, 1.0, and 2.0). These ...
Structure of molecular liquids: cavity and bridge functions of the hard spheroid fluid
(American Physical Society, 2006-06-28)
We present methodologies for calculating the direct correlation function c(1,2), the cavity function y(1,2), and the bridge function b(1,2), for molecular liquids, from Monte Carlo simulations. As an example we present ...
Tandem reactions via Barton Esters with intermolecular addition and vinyl radical substitution onto indole
(American Chemical Society, 2014-05-16)
A one-pot initiator-free Barton ester decomposition with tandem radical addition onto alkyl propiolates or phenylacetylene with aromatic substitution of the resultant vinyl radical allows convenient access to new 9-substituted ...
