摘要:
Provided is an aerosol method, and accompanying apparatus, for preparing powdered products of a variety of materials involving the use of an ultrasonic aerosol generator (106) including a plurality of ultrasonic transducers (120) underlying and ultrasonically energizing a reservoir of liquid feed (102) which forms droplets of the aerosol. Carrier gas (104) is delivered to different portions of the reservoir by a plurality of gas delivery ports (136) delivering gas from a gas delivery system. The aerosol is pyrolyzed to form particles, which are then cooled and collected. The invention also provides powders made by the method and devices made using the powders.

摘要:
A system for displaying luminescence comprises a crystalline structure comprising a compound having the formula:.alpha.-CuAlX.sub.4wherein the compound has lattice parameters a=b ranging from 5.430(1) .ANG. to 5.751(3) .ANG.; c ranging from 10.069(1) .ANG. to 10.570(4) .ANG.; and X is selected from the group consisting of chlorine, bromine, and a mixture thereof. The crystalline structure may also include a compound of the formula:.beta.-CUAlCl.sub.4wherein the compound has lattice parameters a=7.635(2) .ANG., b=12.842(2) .ANG., and c=6.127(1) .ANG.. The system also includes an excitation source which transmits energy to the crystalline structure such that the crystalline structure displays luminescence. The crystalline structure is also useful in a gas sensor application since the luminescence of the crystalline structure is capable of being quenched in the presence of gaseous material.
