Recently, there have been enormous efforts to tailor the properties of graphene. These improved properties extend the prospect of graphene for a broad range of applications. Plasmas find applications in various fields including materials science and have been emerging in the field of nanotechnology. This review focuses on different plasma functionalization processes of graphene and its oxide co...

The verification of a successful covalent functionalization of graphene and related carbon allotropes can easily be carried out by Raman spectroscopy. Nevertheless, the unequivocal assignment and resolution of individual lattice modes associated with the covalent binding of addends was elusive up to now. Here we present an in situ Raman study of a controlled functionalization of potassium inter...

Biochemical functionalization of surfaces is an increasingly utilized mechanism to promote or inhibit adhesion of cells. To promote mammalian cell adhesion, one common functionalization approach is surface conjugation of adhesion peptide sequences such as Arg-Gly-Asp (RGD), a ligand of transmembrane integrin molecules. It is generally assumed that such functionalization does not alter the local...

C–H Functionalization has the potential to become a paradigmshifting strategy for organic synthesis. Over the last decade, the field has experienced explosive growth and a large variety of new C–H functionalization methodologies have been developed. In particular, regioselective functionalization of sp2 C–H bonds has become a broadly flexible approach for the synthesis of complex aromatic carbo...

Chemical Functionalization is a technique used to increase the dispersion and solubility of single-walled carbon nanotube (SWCNT). Functionalization of a (10, 0) zigzag nanotube segment containing 80 C atoms was investigated with the aide of spinunrestricted density functional theory (DFT). The (10, 0) was funtionalized with three organic acid groups: (a) carboxylic acid, (b) aromatic dicarboxy...

this review focuses on the latest developments in applications of carbon nanotubes (cnts) in medicine. a brief history of cnts and a general introduction to the field are presented. then, surface modification of cnts that makes them ideal for use in medical applications is highlighted. examples of common applications, including cell penetration, drug delivery, gene delivery and imaging, are giv...

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 butyl amine) under a nucleophilic substi...

   In this research, Graphene was synthesized by chemical vapor deposition (CVD) method in atmosphere pressure (14.7 psi). Different functionalization method was used for oxidizing of graphene such as acid and alkaline treatments. The Functionalized graphene (FG) was characterized by FTIR and Raman spectroscopy. Nanofluid with water and different concentration (0.05, 0.15 and 0.25 wt %) of ...

The functionalization of C-H bonds has created new approaches to preparing organic molecules by enabling new strategic "disconnections" during the planning of a synthetic route. Such functionalizations also have created the ability to derivatize complex molecules by modifying one or more of the many C-H bonds. For these reasons, researchers are developing new types of functionalization reaction...
