Functionalization of multiwalled carbon nanotubes (MWCNTs) with NH2 groups under a one pot reaction is studied. During the first step of the reaction, Cl and CHCl2 groups were attached to the surfaces of MWCNTs through an electrophilic addition reaction. In the second step of process, Cl atoms were replaced with NH2 and amino groups (ethylene diamine and but...

Special preparation of Santa Barbara Amorphous (SBA)-15, mesoporous silica with highly hexagonal ordered, these materials have been carried out for creating adsorbents exhibiting an enhanced and partially selective adsorption toward CO₂. This creation starts from an adequate conditioning of the silica surface, via a thermo-alkaline treatment to increase the population of silanol species on it. ...

DNA microarrays are powerful tools for gene expression analysis and genotyping studies in research and diagnostic applications. A high sensitivity and short time-to-result are prerequisites for their practical application in the clinic. The hybridization efficiency of DNA microarrays depends on the probe density and the probe orientation and thus their accessibility for target molecules. In ord...

a simple ion imprinted amino-functionalized sorbent was synthesized by coupling activated carbon with iminodiacetic acid, a functional compound for metal chelating, through cyanoric chloride spacer. the resulting sorbent has been characterized using fourier transform infrared spectroscopy (ft-ir), elemental analysis, thermogravimetric analysis (tga) and evaluated for the preconcentration and de...

The design of new flame retardants (FR) that avoid the use halogen and phosphorus additives is challenging urgent. Herein we report on synthesis bis-amino functionalized N-heterocyclic carbene cyclopentadienone iron complexes aimed at promoting production containing epoxy resins. Iron are successfully employed to obtain high Tg thermosets with as low 5% hardener content. Moreover obtained resin...

A series of block copolymers bearing a single amino in-chain functionality was synthesized via anionic polymerization of styrene and ethylene oxide. By means of both a conventional and a continuous setup, living polystyrene was quantitatively end functionalized with an oxirane (DBAG) prior to the polymerization of the poly(ethylene oxide) segment. The in-chain amine was conjugated with a fluore...

Amino-functionalized SBA-15 type mesoporous silicas having unique hexagonal platelet morphologies with short channels (100-300 nm) running parallel to the thickness of the nanostructured hexagonal platelet type morphologies have been directly synthesized by co-condensation of aminopropyltriethoxysilane (APTES) and sodium metasilicate as a silica source in the presence of Pluronic P123 triblock ...

The N-(pyrrolidin-2-ethyl) glycine-based PNA (pet-PNA) backbone, with 4-amino or 4-guanidino-functionalized pyrrolidine ring, confers constrained conformational flexibility on aegPNA. The oligomers bind to the target DNA and RNA sequences with increased sequence specificity and antiparallel versus parallel orientation selectivity. The easy post-synthetic guanidination gives very good access to ...

An efficient amino acid-/self-/base-/ruthenium-/thermal-catalyzed two-step process for the synthesis of functionalized drug-like carbocycles was achieved through combinations of cascade TCRA/C-allylation/enyne-RCM/Diels-Alder reactions as key steps starting from simple acyclic substrates. In this communication, we report the two-step synthesis of drug-like carbocycles through a combination of o...
