A series of rhodium(III) bis(quinolinyl)benzene (bisq(x)) complexes was studied as candidates for the homogeneous partial oxidation of methane. Density functional theory (DFT) (M06 with Poisson continuum solvation) was used to investigate a variety of (bisq(x)) ligand candidates involving different functional groups to determine the impact on Rh(III)(bisq(x))-catalyzed methane functionalization...

Controlling the chemistry on the surface of new carbon materials is a key factor to widen the range of their applicability. In this paper we show a grafting methodology of polyalkylamines to the surface of carbon nanomaterials, in particular, carbon nanotubes and a carbon black. The aim of this work is to reach large degrees of covalent functionalization with hyperbranched polyethyleneimines (H...

Single-stranded DNA (ssDNA) with repetitive sequence was demonstrated to be a versatile nanotemplate for introducing biological activity in a self-assembled manner. Re-functionalization and rejuvenation of the ssDNA nanotemplate were achieved under mild biological conditions without using high temperature and strong alkaline treatment to denature DNA.

Bio-functionalization of nanoparticles has received enormous attention due to reduced toxicity as well as stability in colloidal state which prevents the nanoparticles from aggregation [1,2]. The biomolecules being used for functionalization vary from simple to complex macromolecules [3]. Starch, a natural polymer widely used in many industries as raw material was chosen for synthesis of silver...

Linear hydrophilic derivatives are expected to soften lignin and improve its utilization in composite applications. Oxidation by means of laccase in the presence of oxygen was employed in an attempt to functionalize commercial kraft lignin by vanillic acid-PEG ester and ether derivatives. Thielavia arenaria and Melanocarpus albomyces laccases at pH 6 and 8 were used. According to O2 consumption...

A simple and inexpensive method to functionalize hexagonal boron nitride (hBN) was achieved by using an acid mixture of phosphoric and sulphuric acid. This functionalization induced the exfoliation of the layered structure of hBN into monolayer to few-layer sheets where the sizes of the sheets were dependent on the parent hBN powder used. Exfoliated hBN was shown to be stable in solvents such a...

In this paper, the chemical functionalization of carboxylated multi-walled carbon nanotubes (MWNT-COOH) by 1,2-phenylenediamine, have been investigated. MWNT-benzimidazole is obtained through MWNT-Amide reaction with POCl3 after 72h, which is confirmed by FT-IR, SEM, TGA, and elemental analysis. These functionalizations have been chosen due to –NH2 and NHCO active sites in MWNT-Amide for future...
