The electroless plating reactions on catalyzed nanoporous γ-alumina surfaces were carried out in an emulsion of supercritical carbon dioxide (sc-CO2) and an electroless plating solution with fluorinated surfactant F(CF(CH3)CF2O)3CF(CF3)COO(CH2CH2O)CH3. Pd/γ-alumina graded membrane produced by electroless plating with sc-CO2 had thicker Pd/γ-alumina graded layer and smoother surface than conventional electroless plating. In electroless plating with sc-CO2, the penetration into the nanoporous γ-alumina pores was dominant reaction because the deposited Pd particles were smaller and, moreover, the electroless plating media with dispersed CO2 has lower viscosity than conventional electroless plating. The Pd membrane formed in the emulsion of sc-CO2 was about 1μm thickness and composed of a composite membrane of 0.45molm−2min−1 as hydrogen flux, while 0.30 molm−2min−1 of the Pd membrane formed by conventional electroless plating.

Some historians considered these years as an age of shift from the pagan Viking Age to the Christian Middle Ages.1 However we have to pay more attention to the century to deeply understand that various innovative shifts were progressing politically, economically, socially and culturally. My paper aims to make clear one aspect of these shifts, that is the background of the transformation of property confirmation in Denmark at the gate of the early Middle Ages. The central concern exists in how and why Denmark, non-successor state of the Roman empire, adopted the way of property confirmation through written documents into its own system of land management.

Consider, for example, the text inscribed upon them. The first, by King Gorm, reads:

The smaller stone was erected by a Danish king, Gorm the Old ( -958), while the larger one was erected by his son and successor, King Harald Bluetooth (-987). These two rune stones are among the most famous of more than 2500 examples of rune stones in all Scandinavia, and are at least among the most impressive of all the Danish examples in two ways. One way in which Harald’s stone impresses the onlooker is because of the magnificent images drawn on two faces of the stone: the “Jelling beast” and the crucified Christ. The other reason is that these two stones are among the very few examples that can be testified by their inscriptions to have been raised by kings of the Danes. Historiography has been accumulating on these two Jelling stones since the time of the 16th-century antiquarians Henrik Rantzau, in Holstein, Ole Worm in Denmark and J...
