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

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

A new method is shown for lower temperature preparation of tungsten oxide thin film by sol-gel process without using a catalyst, but using tungsten chloride (WCl 6 ) as the starting material and ethanol as a solvent. When WCl 6 dissolved in ethanol,

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

Spinel oxide ZnGa 2 O 4 thin films were prepared on SiO 2 glass substrates by a sol—gel process using inorganic salts as raw materials. The conduction path in the crystal was confirmed by measurement of the photo-current of the film. Reduction of t
