Diamond properties down to the quantum-size region are still poorly understood. High-
pressure high-temperature (HPHT) synthesis from chloroadamantane molecules allows …

Following our previous brief communication the carbonization of halogenated adamantanes
C 10 H 14 Br 2 and C 10 H 15 Cl under high pressure with the aim to produce …

High-pressure high-temperature (HPHT) nanodiamonds originate from grinding of diamond
microcrystals obtained by HPHT synthesis. Here we report on a simple two-step approach to …

The synthesis of diamonds from hydrocarbons at high static pressures, first performed by
Wentorf more than half a century ago, is becoming an extremely important technology for …

The high‐pressure and high‐temperature technique is the most promising for mass
production of ultra‐small diamond nanoparticles of perfect structure. In the present work, this …

Bottom-up high-pressure, high-temperature (BU_HPHT) synthesis of nanodiamonds (NDs)
from organic precursors has recently enabled unprecedented control over the ND size down …

Understanding materials with dimensions down to a few nanometers is of major importance
for fundamental science as well as prospective applications. Structural transformation and …

Abstract Nanodiamond in a 2–5-nm size interval (which is typical for an appearance of
quantum confinement effect) show Raman spectra composed of 3 bands at 1325, 1600, and …

Nanodiamond particles with typical diameters of 20 and 6 nm produced by high pressure
high temperature or detonation processes have been studied by micro-Raman …

Structural characterization of nanodiamonds by vibrational spectroscopy requires
knowledge of the factors determining the spectra. Raman spectroscopy is widely used to …
