This reduction can also be carried out with molecular hydrogen and as such is probably not of any commercial interest. However, it is suited for the study of the catalytic properties of the ultrafine powders and serves as a characterization and optimization technique for the titanium nitride nanoparticles in this study. 

Regulation 10/2011/EU of the Commission concerning plastic materials and objects that will come in contact with food products, OJEU, no. L 12/2011, pp. 1-89. A unique substance in the nanometric form is currently featured in the union lisf on line 807. It involves titanium nitride nanoparticles. It indicates that they can be used in PET bottles (for Polyethylene terephthalate) at a maximum of 20 mg/kg .

Titanium nitride-based nanoparticles are also efficient dopants for NaAlH4 in hydrogen storage applications [12, 13]. The black solid TiN powder can be dispersed into the hydride via ball milling. Addition of titanium nitride-based na-...

Ti02 (nanotubes or nanoparticles) were used as the precursor to the corresponding nitride. Nitrides were prepared by nitriding equal amounts of Ti02 (NPs or NTs) and melamine in NH3 at 900 C using slow ramp rates. This resulted in a series of carbon-coated titanium nitrides. Pure TiN phases were also synthesized in the absence of melamine to study any effects that are purely a result of the nitride. 

Titanium Nitrides. Titanium nitride (TiN) with a surface area of 28 m /g was synthesized from TPR of Ti02 with ammonia at the final reaction temperature of 1223 K (48). TiN showing a higher surface area was fabricated by nitridation with anatase Ti02 nanoparticles (10-15 nm) (49). The reaction was carried out with a NHs flow rate of 1 L/min at 1073 K. The surface area was 55 m /g originated from the TiN nanoparticles of 20 nm, but it decreased (from 33 to 15 m /g) as the nitridation temperature increased from 1173 to 1373 K. 

A review of the literature showed that the nanoparticles used in the production of nanofluids were aluminum oxide (AI2O3), titanium dioxide (Ti02), nitride ceramics (AIN, SiN), carbide ceramics (SiC, TiC), copper (Cu), copper oxide (CuO), gold (Au), silver (Ag), silica (Si02) nanoparticles and carbon nanotubes (CNT). The base fluids used were water, oil, acetone, decene and ethylene glycol. Modem technology allows the fabrication of materials at the nanometer scale, they are usually available in the market under different particle sizes and purity conditions. They exhibit... 

Boron nitride nanocages with silver nanoparticles encapsulated in them have been synthesized by Oku et al." Reaction of urea and boric acid in the presence of silver nitrate produced BN matrices at 700°C. The ingredients were previously dissolved in deionized water and dried consequently to produce a homogenous mixture and annealed separately at 300°C and 700°C. The presence of silver nanoparticles and sometimes silver oxide nanoparticles were detected under TEM (Figure 20.15a) and x-ray diffraction studies. A similar methodology has been developed by Xing et al. in their preparation of zinc oxide- and titanium oxide-encapsulated BN nanocages." ...
