CHEMISTRY: Higher Order Electron Transfer

Higher-Order Chemistry

Gamma is a formalism in which programs are expressed in terms of multiset rewriting often referred as the Chemical Reaction Model. In this paper we are concerned with higher-order Gamma programming. First we review three proposals which introduce the notion of membrane and higher order facilities. Finally, we propose a higher-order Gamma which allows the definition of γ-abstractions (in the sam...

The Electron Transfer Chemistry of Nitrosyl Complexes

Covalent electron transfer chemistry of graphene with diazonium salts.

Graphene is an atomically thin, two-dimensional allotrope of carbon with exceptionally high carrier mobilities, thermal conductivity, and mechanical strength. From a chemist's perspective, graphene can be regarded as a large polycyclic aromatic molecule and as a surface without a bulk contribution. Consequently, chemistries typically performed on organic molecules and surfaces have been used as...

Free Radical Chemistry Enabled by Visible Light-Induced Electron Transfer

Harnessing visible light as the driving force for chemical transformations generally offers a more environmentally friendly alternative compared with classical synthetic methodology. The transition metal-based photocatalysts commonly employed in photoredox catalysis absorb efficiently in the visible spectrum, unlike most organic substrates, allowing for orthogonal excitation. The subsequent exc...

Electron transfer chemistry of octadecylamine-functionalized single-walled carbon nanotubes

Single-walled carbon nanotubes were chemically functionalized by virtue of the interactions between the nanotube-bound carboxylic moieties and octadecylamine ligands. The electronic conductivity properties of the resulting nanotubes were probed voltammetrically. Two approaches were employed. The first entailed the fabrication of a nanotube monolayer at the air|water interface and the conductivi...
