We demonstrate that addition of ND to a polyimide matrix increases the thermal degradation temperature of the composites up to 30 °C and also improves adhesion. The addition of 2 wt.% of ND increases thermal conductivity of PDMS up to 15%. Finally, we also demonstrate that the addition of OLC to polydimethylsiloxane and polyurethane matrices increases the loss tangent of the composites.}, number={4-7}, journal={DIAMOND AND RELATED MATERIALS}, author={Shenderova, O. and Tyler, T. and Cunningham, G. and Ray, M. and Walsh, J. and Casulli, M. and Hens, S. and McGuire, G. and Kuznetsov, V. and Lipa, S.}, year={2007}, pages={1213–1217} }

Aging is a crucial effect that is observed in as-grown individual nanoparticles only. This effect was investigated for as-grown nanodiamond particles exposed and non-exposed to field emission experiments. It was shown that under field emission exposure the sp2 fraction in as-grown structures starts increasing from the surface of the particles and this process continues up to the whole particle phase transition. Nitrogen is potentially a donor dopant in diamond but there were no experimental results describing the nitrogen behavior in diamond nanoparticles, in large part, due to the nanometer scale of the structures. In this paper the clear indications of nitrogen impurities imbedded in bulk of nanodiamond are presented. By field electron emission measurements it was shown that a single isolated diamond particle on a metal tip substantially increases the emission voltage. The major characterization techniques are Z-contrast imaging using scanning transmission electron microscopy, electron energy loss spectroscopy and high-resolution transmission electron microscopy.}, number={2}, journal={COMPOSITES PART B-ENGINEERING}, author={Kvit, AV and Zhirnov, VV and Tyler, T and Hren, JJ}, year={2004}, pages={163–166} }

Combined transmission electron microscopy observations, field emission measurements, and diamond depositions allowed for direct comparison of the effects of various amounts of nanodiamond coating on the field emission properties of a coated metal field emitter. In the limit, field emission from a single isolated diamond nanoparticle is compared here with that from an uncoated metal emitter and from a coating comprised of several layers of nanoparticles.}, number={17}, journal={APPLIED PHYSICS LETTERS}, author={Tyler, T and Zhirnov, VV and Kvit, AV and Kang, D and Hren, JJ}, year={2003}, month={Apr}, pages={2904–2906} }

Recently nanocrystalline hexagonal GaN crystallites as small as 12 nm average diameter have been formed using reactive laser ablation of gallium metal in nitrogenating ambient [T. J. Goodwin et al., Appl. Phys. Lett. 70, 3122 (1997)]. In this article we investigated the performance of ungated emitters with and without surface coating. Silicon tip arrays are coated by dielectrophoresis of gallium nitride nanoparticles or nanocrystalline diamond clusters from an ethanol suspension. The emitters were evaluated and compared before and after the surface treatment using SEM image and I–V measurements in the diode configuration. The results suggest that the emitters benefit from coating the surface with nanocrystalline diamond clusters in terms of reduction in the turn on voltage by 100 V and increase uniformity in emission during low voltage operation. The long-term emission stability for both types of the coated cathodes was studied over a period of 90 h. The emitters coated with GaN nanoparticle clusters show a significant improvement in the current fluctuation from 150% (for untreated cathodes) to 50%.}, number={1}, journal={JOURNAL OF VACUUM SCIENCE & TECHNOLOGY B}, author={Hajra, M and Chubun, NN and Chakhovskoi, AG and Hunt, CE and Liu, K and Murali, A and Risbud, SH and Tyler, T and Zhirnov, V}, year={2003}, pages={458–463} }
