Ultrasonic precipitation is known to give narrower particle size distribution, smaller crystal size,controllable morphology and as well as fast nucleation rate.
Through the use of this technology, particle core generation and particle growth can be controlled, enabling us to freely control the size of particles.
Not only is key information about the particle size, shape and struc ture observed butdynamic mechanisms such as growth, nucleation, agglomeration breakage and shape change are visualized and quantified.
The acquired data gave the temperature and concentration of nucleation*, and provided estimates of the aggregation rate of iron atoms from the cooling rate of iron gas and other factors.
In this project, we will perform in-situ transmission electron microscope(TEM) observation using a liquid cell andshow the direct evidence of a relationship between nucleation and precursor.
Gas evaporation method is usually used for the dry production of nano-powder, with the principle of the supersaturation concentration of metal vapor in the absence of refrigerant andcrystal nucleation carrier gas such as argon, nitrogen.
Mr. Kimura successfully used an independently developed and mounted dual-wavelength interferometer to measure nucleation environments to simulate the process of dust formation from iron vapor and directly perform homogeneous nucleation experiments compatible with nucleation theory.

結晶核生成によって液体濃度が下がり、その後は溶解度曲線に近い状態を維持します。
The liquid concentration decreases upon crystal nucleation and stays close to the solubility curve.
まあ装置は彼らにも分かり易いようにシモンズが結晶核生成プロセスを応用し設計した。
Well, as far as they can tell, the device uses a crystalline nucleation process she designed.
すると1nmレベルからの幅広いサイズの核生成が散乱強度の増大としてリアルタイムでとらえられた。
The increased scattering intensityconfirmed in real time that various sized nuclei(< 1 nm) are produced, and this is the first observation of nano-nucleation.
第一段階-結晶の一次核生成、第二相-結晶の成長は、一定の速度です。
The first phase- the primary nucleation of crystals, the second phase-the growth of crystals is, a certain speed.
This has changed the structure of the primary anomaly around the planetary surface significantly, and we have entered the next phase of the Compression Breakthrough,the so-called nucleation phase:.
