摘要： PROBLEM TO BE SOLVED: To provide a nanoparticle distribution method, in which particulates of nano order can be stably and uniformly distributed without reaggregation with little inclusion of impurities due to the wear of a stirring particle.
SOLUTION: This invention relates to the nanoparticle distribution method, in which aggregated particulates having an average first particle diameter of not more than 100 nm are stirred together with stirring particles in a dispersion medium, thereby the aggregated particulates are disaggregated, and the disaggregated particulates are dispersed in the dispersion medium. A particle diameter of the stirring particle to be used is 200 to 10,000 times the above average first particle diameter.

摘要： PROBLEM TO BE SOLVED: To provide an organic solar cell that is further improved in photoelectric conversion characteristic. SOLUTION: In this organic solar cell, an active layer 3 containing an electron donating organic compound and compound semiconductor particles is provided between positive and negative electrodes 1 and 2. The compound semiconductor particles are contained in the active layer 3 in a state where the particles are aggregated in a row in a direction almost perpendicular to the surfaces of the positive and negative electrodes 1 and 2 between the electrodes 1 and 2. Since the electrons caught by the compound semiconductor particles reach the negative electrode 2 in a short range along the row of the compound semiconductor particles, the photoelectric conversion efficiency of this organic solar battery cell is improved.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a thermoelectric conversion module which is equipped with thermoelectric elements excellent in mechanical strength and thermoelectric conversion performance. SOLUTION: Thermoelectric conversion elements 2 of P-type and N-type are formed through such a manner that thermoelectric conversion material powder of P-type and N-type is preliminarily molded into elements on a copper plate 1 and burned. Then, the rear side of the copper plate 1 is bonded to an aluminum board 4. Thereafter, the copper plate 1 is cut into electrodes, and the thermoelectric conversion elements 2 are separated from each other. Then, a solder layer 10 is formed on the surface of the copper plate 1 cut in the shape of electrodes. Thereafter, a ceramic pillar 20 is formed between a P-type board 7 and an N-type board 8. The P-type board 7 and the N-type 8 are pasted together, the thermoelectric conversion elements 2 provided to one of the boards and the solder layer 10 of the other board are made to overlap with each other and heated, whereby the P-type board 7 and the N-type board 8 are bonded together with solder.

摘要： PURPOSE:To rapidly obtain high-purity and fine particulate readily sinterable AlN powder at a low cost by sintering a mixture of an Al-containing compound with beta-alanine in a nonoxidizing atmosphere containing N2. CONSTITUTION:An Al-containing compound, such as Al(NO3)3 or AlCl3, is homogeneously mixed with beta-alanine in a state of an aqueous solution and dried to remove moisture and afford a mixture. The drying temperature in this case is, e.g. within the range of 70-200 deg.C, more preferably about 100-200 deg.C. The above- mentioned mixture is then calcined at >=900 deg.C, preferably about 1200-1800 deg.C in a nonoxidizing atmosphere, such as Ar, containing N2, to afford the objective AlN powder. The afore-mentioned AlN powder in a state of an added sintering assistant, such as Y2O3, is then sintered at >=1200 deg.C, preferably about 1400-2000 deg.C in the same nonoxidizing atmosphere as that described above to afford a sintered AlN compact.
