The observations of snow crystals have been made using a stereoscopic microscope at Mizuho Station, Antarctica during March 1979 and January 1980. Hollow prisms were observed rather in excess together with different shapes of snow crystals. Crystallo

The inhibitory growth mechanism controlling the growth of ice crystals due to the presence of saccharides, as in plant cells, was experimentally studied at low temperature. As a result, it was found that the growth rate of ice crystals in saccharide

In-situ observations have been made of ice crystals growing in solutions of trehalose and water in order to investigate how trehalose suppresses the growth of ice crystals and protects organisms from the freezing of their cellular water. In the range

雪結晶の形態変化即ち晶癖変化と形態不安定は,温度と過飽和度のみではなく気体の圧力と結晶サイズによって変化する.形態変化の気体の圧力の影響は,結晶のサイズが小さいとき特に顕

In-situ observations of needle ice crystals growing in air at 10^5 Pa at -7℃ and at about water saturation and above water saturation were performed to study the formation process of the branches of needle ice crystals. At about water saturation, s

The melting process of ice crystals just below the melting point was investigated by in situ observation. We found that an ice crystal just below the melting point started to melt at the positions where dislocations or stacking faults emerged on the

The melting point of ice in trehalose and sucrose solutions was measured by in situ observations of a minute ice crystal. It was found that the concentration dependence of the melting point of ice in both trehalose and sucrose solutions was identical

The evaporation rate of a polyhedral ice crystal is several times larger than the growth rate. The reason is because the slope of an evaporation pit P_e of the ice crystal is larger than the slope of a growth hillock P_g in addition to the increase o

Dendritic ice crystals with faceted tip are formed in air of 1.0 × 10 5 Pa at − 15°C and just below water saturation. When large concaves are formed on two prismatic facets at the tip of primary branches, dendritic ice crystals with side branches
