These materials are mainly obtained by detonation of two water-in-oil (W/O) emulsions, one of which is prepared with precursors in order to present a detonation regime with temperature lower than 2000° C., and they present a high chemical and crystalline phase homogeneity, individually for each particle, as well as a set of complementary properties adjustable according to the final applications, such as a homogeneous distribution of the primary particles, very high chemical purity level, crystallite size below 50 nm, surface areas by mass unit between 25 and 500 m2/g, and true particle densities higher than 98% of the theoretical density. This set of characteristics makes this materials particularly suitable for a vast range of applications in the nanotechnology field, such as, for example, nanocoatings, magnetic nanofluids, nanocatalysts, nanosensors, nanopigments, nanoadditives, ultra light nanocomposites, drug release nanoparticles, nanomarkers, nanometric films, etc.

Abstract: An apparatus and method for in situ gas-phase formation and deflagration of nitrocellulose. A nitrating agent such as nitric acid and cellulose are delivered separately to a reaction chamber, where a brief heating pulse initiates nitration of the cellulose and deflagration of the nitrocellulose thus produced. Discharge of the high-pressure gases produced by the deflagration from the reaction chamber can then be used to drive an actuator, turbine, etc.

Abstract: An aerosol of a powder composed of helium carrier gas and particles of a hexagonal aluminum nitride is charged through a transfer pipe 3 into a film deposition chamber 4 whose interior is depressurized by gas evacuation using a vacuum pump 5 to maintain a degree of vacuum of 200-8000 Pa during supply of the carrier gas and the aerosol is blown from a nozzle 6 provided on the end of the transfer pipe 3 inside the film deposition chamber 4 to impinge on a substrate fastened to a substrate holder 7 to make the impact force of the particles at collision with the substrate 4 GPa or greater, thereby transforming the crystal structure of the aluminum nitride from hexagonal to cubic to deposit cubic aluminum nitride on the substrate. As a result, a method of transforming the crystal structure of a Group XIII nitride is provided that enables transformation of a Group XIII nitride to cubic crystal structure using a system of simpler configuration than that used for transforming the crystal structure of a Group XIII nitride by a static pressure application process.

Abstract: Methods of synthesizing superabrasive particles such as diamonds and cubic boron nitride are disclosed and described. One procedure includes providing a superabrasive precursor including a source material in a metal matrix. The carbon source can contain a majority of carbon atoms oriented in a rhombohedral polytype configuration. A shock wave can be passed through the carbon source that is sufficient to convert the diamond to graphite. The superabrasive precursor can be formed by dissolving hexagonal carbon in a suitable molten metal or by mixing particulate components. Similarly, hexagonal boron nitride can be used in a metal matrix which is subjected to a shock wave having sufficient energy to form cubic boron nitride. The superabrasive particles produced using these methods can be provided at relatively high yields with reduced costs.

Abstract: Pluralities of ultrasonic transducers are arranged on the bottom wall of the cleaning tank. The output power of the ultrasonic oscillator is supplied to the transducers through the switching unit, which switches the drive mode between a first mode in which all the ultrasonic transducers are supplied with the output power and thus are excited, and a second mode in which only a part or parts of the ultrasonic transducers are supplied with the output power generated by the ultrasonic oscillator. The first mode is used when cleaning substrates not-resistant to vibration, and the second mode is used when cleaning substrates resistant to vibration.
