Nanodiamonds

Nanodiamonds: Advanced Material Analysis, Properties and Applications illustrates the complementarity of specific techniques to fully characterize nanodiamonds from their diamond core (crystalline structure, defects, sp2 carbon, impurities, strain) to their surface (surface chemistry, stability of surface groups, reactivity, surface charge, colloidal properties).

The relationship between physical and chemical parameters sits at the heart of what this book is about. Recent advances in the synthesis of nanodiamonds either by HPHT or detonation are covered, along with extended characterization of the core and surface of nanodiamonds, focusing on the most advanced experimental tools developed for nanoscale diagnosis.

Each technique presented includes presentation of both principles and applications. This combination of advanced characterizations offers readers a better understanding of the relationship that exists between physical and chemical parameters of nanodiamonds and their properties.

In particular, the role of structural defects or chemical impurities is illustrated. Toxicity of nanodiamonds for cells is also discussed, as It is an essential issue for their bioapplications. Final sections in the book cover the main promising new advances and applications of nanodiamonds, the formation of hybrids, and their use in polymer and oil composites.

Jean-Charles Arnault is currently Research Director at CEA. He obtained his PhD in 1993 at Poitiers University, France. From 1993 to 2007, he was assistant professor at Strasbourg University and obtained his HDR in 2001. His research activities in Strasbourg concerned diamond nucleation on different substrates and interactions between MPCVD plasmas with surfaces using in situ surface analysis methods (electron spectroscopies), and scanning probe microscopies. These studies were completed by electron microscopies. In 2003, he moved to the "Physics and Chemistry of Surfaces and Interfaces" at CEA for a research period focused on diamond on reconstructed cubic silicon carbide surfaces (2003-2007). Since 2007, he performed his research activities in the Diamond Sensors Laboratory at CEA. His research interests are currently focused on diamond nanoparticles, diamond heteroepitaxy and the growth of boron doped single crystalline diamond. For diamond nanoparticles, surface modifications by MPCVD plasma or annealing are performed to control their surface terminations for efficient grafting. Intrinsic properties of hydrogenated and surface graphitized nanodiamonds were investigated during the last years especially for bioapplications. In 2008, he initiated diamond heteroepitaxy on iridium at CEA. This topic is now developed in collaboration with a French consortium involving four other groups. Jean-Charles Arnault is regularly involved in the organization of international symposia related to these topics (Spring and Fall MRS, E-MRS). In January 2015, he became an Editor of Diamond and Related Materials. He contributed recently to three chapters of book, two of these chapters concern diamond nanoparticles.
