چکیده
Detonation nanodiamonds (DNDs) are known to be produced in aggregated clusters of a few nanometer-sized primary crystalline particles embedded an amorphous carbon matrix exhibiting high degree polydispersity. A commonly accepted mechanism behind DND aggregation is the bridging via oxygen containing functionalities. Here, we provide definitive spectroscopic evidence favor this working by carrying out systematic chemical compositional analysis on monodispersed aggregates various sizes. Oxygen content found increase proportionally with aggregate size confirming role functionalities as cross-linker. Solid-state nuclear magnetic resonance data confirms these linkers ether (COC) nature. Our results imply that DNDs can independently tuned varying size, knowledge which might benefit other applications, addition. Next, use understanding engineer surfaces acid hydrolysis step strip off leading reduction ca. 150 nm as-received 40 >90% yields, without resorting any pre- or post-hydrolysis treatment such surface functionalization milling.

Nuclear Magnetic Resonance (NMR) is a spectroscopic technique widely used by organic chemists. NMR provides details about the location, number and environment of specific types of atoms within a sample. The proper interpretation of this information allows detailed chemical structures to be discerned. The same basic instrumentation used in this week’s experiment is used in physician offices when...

Background: Analysis of biofluids provides a unique window into the biochemical status of a living organism since the composition of a given biofluid will be modulated according to the level of function of the cells that are intimately concerned with its manufacture and secretion. One of the most successful approaches to biofluid analysis has been the application of NMR spectroscopy. Objective...
