    One of the goal of holography is to obtain a three-dimensional image in natural color. By recent development of the new recording material and its processing, the possibility of higher level utilization of color holography is being realized. One of the promissing application of the color holography is to record cultural assets and to demonstrate them by hologram. To realize this, analysis of the color reproduction and discussion of the color hologram as the color recording system is necessiated.
    In this paper, the color of the image reconstructed by a Lippmann color hologram is evaluated using CIE chromaticity diagram for the first report of the study on the application of color holography to the recording and demonstration of the cultural assets. The wavelengths of the three recording primaries for optimizing the color reproduction are calculated taking into account the wavelength selectivity of the hologram.

    One of the most important application of color holography is to record cultural assets and to demonstrate them by holograms. For this purpose, the discussion of the methods for recording the color hologram is necessiated together with analysis of the color reproduction.
    In this paper, the Lippmann color hologram using a holographic stereogram is presented for the second report of the study on the application of color holography to recording and demonstration of the cultural assets. This method is considered as the promissing method to realize the optimum color reproduction discussed in the first report of this study. The color hologram is recorded with only one wavelength by using the technique of pseudo-color hologram. The reconstructed wavelengths for the three primaries can be chosen freely by controlling the thickness of the photographic emulsion properly in the recording stage. The perspective images for holographic stereogram are obtained photographically, so the restriction for the object to be recorded is removed. The color hologram having these features are suitable for the application mentioned above.

    Although phenomena such as host-guest inclusion complex formation, the ability of detergents to solubilize otherwise insoluble solids in water, the formation of phospholipid bilayers and membranes, and the spreading of oil or amphiphilic molecules to give a monomolecular film at the air-water interface, have been long recognized, recent advances in structural characterization and spectroscopic techniques have led to a better definition of the interfaces involved in these phenomena and to a resurgence of interest in reactivity at these interfaces. In this tutorial we will focus on recent studies and developing possibilities for controlling photochemical and photophysical processes in layered Langmuir-Blodgett (LB) assemblies fabricated from sequential transfer of monolayers formed at the air-water interface to rigid supports.

    In order to induce by light demanding interfacial reactions for energy conversion and catalysis, it is generally not sufficient to provide photoexcited electrons for tunnelling processes. Multi-electron transfer processes and efficient catalytic mechanisms require specific chemical bonding conditions. It is therefore reasonable to develop photoactive materials which transfer electronic charge carriers via states of transition metals, which can induce coordination chemical mechanisms. Experimental evidence that this strategy is feasible is presented on the basis of photoelectrochemical experiments with FeS2 and oxygen reduction catalysis with transition metal cluster compounds of the composition (M, Mo) 6X8 with X=S, Se and M=transition metal.

    The use of silver-containing sodalites as novel materials for reversible optical data storage is proposed. Sodalites can be synthesized with a variety of cation, anion and framework compositions using simple hydrothermal and ion exchange methods. Silver sodalites exhibit unique optical absorption and luminescence properties which can be controlled by tuning the material composition and unit cells sizes. The optical characteristics of these materials can be selectively modified using photons, heat, X-rays, pressure or moisture. A system containing oxalate as internal reducing agent can be reversibly marked with a laser beam for many cycles. The composition, structure, silver distribution and optical features of this material are discussed in detail. A possible mechanism for the reversible changes of silver oxalato -sodalite involves electron transfer between two types of silver clusters occluded in the sodalite framework.
