A new method of rapid crystal growth from a thin solution film has been proposed, in which crystals have been grown from a soap liquid film held with a thin steel loop. Crystal nucleation site and movement of crystals grown in the film can be compared with the experiments in a Space Shuttle done by Donn Petitt. It is interesting to note that nucleation in microgravity takes place mostly on the surface of the metal loop due to heterogeneous nucleation and then these crystals move toward the center of the loop with the help of Marangoni convection. Whereas, under normal gravity, crystal nucleation takes place at the middle of the liquid film and then these crystals move radially towards outside.

Formation process of matrix olivine surface microtopography was experimentally simulated Few μm sized 2-dimentional nucleation growth islands were observed on the surface. It was thought that the difference of the shape of step between sharp and rough depends on whether supersaturation excess the critical supersaturation or not Our experiment indicates that some matrix olivine remained the record that they cooled rapidly more than 500K/sec.

The effect of the contact of the levitated chondrule melts with fim-sized particles, acting as heterogeneous nucleation centers, was investigated for chondrules. Although heterogeneous nucleation is expected to be very easy if an active seeding technique is applied, it was surprisingly that the seeding was effective only within a narrow temperature range.

For the long-term assessment of CO_2 underground sequestration, batch-type dissolution experiments were performed under supercritical CO_2-water system. Surface observation on nano-scale using phase-shift interferometry enabled us to obtain feldspar dissolution rates with high precision. Those data were applied to estimate the porosity change of sandstone.

The research of the surface free energy measurement with the liquid has been advanced. We tried measure surface free energy of the crystal from the contact angle with the liquid this time. The researched synthetic quartz paid attention to metastable faces and we compared surface free energy with the growth rate.

Recently, synthetic quartz crystals were interested in the VUV materials. In this report, we have measured the VUV transmittance of synthetic quartz crystals with various growth rates. It was found that the reduction of transmittance became larger with increasing of growth rate of synthetic quartz crystals.

Stresses in the growing crystal have been measured by experiment of Raman scattering, and calculated theoretically by using molecular dynamics. Peaks in Raman scattering shift to the larger wave numbers as increase the pressure in the system. When we modify the pressure in the simulation system, the results have agreement with the experimental results.

Nobel method has been developed to decrease the cement clinker burning temperature from in-situ microscopic observation results of alite crystal growth. It is revealed that the behavior of alite crystal growth is remarkably influenced by addition of clinker and alite into the starting materials, and in consequence that the firing temperature can be reduced.

The as-deposited (Nd_<1/3>Eu_<1/3>Gd_<1/3>)Ba_2Cu_3O_x (NEG123) films on MgO(100) substrates by metal organic deposition (MOD) method are amorphous and turns into crystalline when it is heated around 900℃. The growth mechanism of MOD is still not yet to understand. In this work, we report in situ observation of growth process of NEG123 films using a high temperature optical microscope. High temperature optical microscope clearly shows that (1) a larger amount of white particles appear at around 890℃, (2) NEG123 plate-like crystals with facet faces are formed in the white particles and (3) many NEG211 needle crystals are grown from flux (Ba and Cu rich particles) at a rate of about 7.5μm/sec.

Behenic acid and calcium stearate thin films evaporated on GaAs substrates were investigated by atomic force microscopy. Behenic acid thin films show platelet islands formed on a behenic acid monolayer. In the case of calcium stearate, however, DLA islands were observed to grow on oxidized GaAs substrates.

It has been clarified that polymer-crystalline-region based composite materials can be prepared with syndiotactic polystyrene (sPS) with guest exchange procedures and solvent-induced crystallization. The structures and properties of guests in the sPS clathrates has been studied with vibrational and NMR spectroscopy, neutron scattering and so on.

By using small and needle-like high-melting fat crystals, oil can be foamed. This property of foaming oil is influenced by high melting fat crystals morphology in low-melting oil, such as size, number and polymorphism, and the morphology is affected by thermal processing conditions, such as supercooling and cooling rate.

The relationship between the molecular structure and crystallization behaviors has been rarely investigated. In this work, esters of a pharmaceutical, BPT was synthesized and the dependence of the nucleation on the molecular structure was examined. It appeared that the size of the alkyl groups in ester very influences on the nucleation behaviors of polymorphs.

We investigate the mechanism of light-induced nucleation of protein. The light-induced nucleation of protein was caused through intermediate protein radical. When the radical was scavenged, nucleation was inhibited. Protein dimmers of lysozyme or ribonucleaseA were deteced by electrophoresis experiments, which indicates that the dimer behaves first cluster formation to from protein nucleus.

We have reported that nucleation of lysozyme was enhanced by the light irradiation. In this study, we examined the effect of light induced nucleation with several precipitant for example KSCN, NaCl and NH_4citrate. As a result, the enhancement of the light-irradiation was NH_4citrate>NaCl>KSCN. We also improved experimental setup and procedures in order to use as a conventional protein crystallization.

We have studied protein crystallization through photochemical reaction. Light-induced nucleation was succeeded in lysozyme and thaumatin system. In this report, we examined light-induced nucleation of catalase. Nucleation was enhanced by light irradiation and its mechanism was considered to be different from the reported mechanism of lysozyme which took place through intermediate residue tryptophan radical. We discussed whether catalase can be a prototype for universal protein system.

A subsequent growth of a single protein crystal was induced by femtosecond laser ablation of protein crystals existing in advance in the supersaturated solutions. Since this technique is available in closed vessels with spatial processing resolution of micrometer order, we succeeded to obtain a single crystal even from a μm-sized polycrystal.

Lysozyme was crystallized on fatty acid thin film substrates prepared on mica and HOPG. Lysozyme crystals with the {110} planes parallel to the substrates were nucleated on fatty acid thin films on mica. The c-axes of {110}-oriented crystals were along the three directions associated with the six-fold symmetry of mica surface. On the other hand, the {110}-oriented crystals did not nucleate on fatty acid thin films on HOPG The effects of the structure of fatty acid thin films are also discussed.

Average step velocities (V_<ave.>) and two-dimensional nucleation rates on the {101} face of glucose isomerase (GI) crystals increased with increasing pressure at C=5.6 mgml^<-1> (C: GI concentration). Solubility curves of the GI crystals were determined by in situ observation of elementary growth steps under 0.1, 25 and 50 MPa. Kinetic coefficients of V_<ave> had a tendency to increase with increasing pressure.
