Studies on the adsorption property of NO on the Ni-based mixed oxide catalysts with Perovskite-like (ABO(3) and A(2)BO(4)) structure

The mixed oxides LaNiO3, La0.1Sr0.9NiO3, La2NiO4 and LaSrNiO4 with perovskite (ABO(3)) and related(A(2)BO(4)) structures were prepared and the adsorption property for NO and the catalytic activity for NO decomposition over these oxidse were also tested. The catalysts were characterized by means of BET surface measurement, chemical analysis, NO-TPD etc.. It was shown that the adsorption amount of NO is correlated with the concentration of oxygen vacancy formed and the adsorption type and strength of NO are related to the valence of metallic ion. Generally there are three kinds of adsorption species, NO-, NO+ and NO on the mixed oxides, among them the negative adsorpion species (NO-) are active for NO decomposition. The weaker the adsorption of oxygen on the catalyst is, the faster the mobility of oxygen is and the easier the redox process takes place in reproducing the active sites in which the oxygen species (O-, O2-) would participate.

From an American Plantation to Interwar Poland: How Uncle Remus Became Bam-Bo the Negro

The article opens with the introduction of Joel Chandler Harris and his literary output. As one of “local colourists,” Harris depicted American plantation life in 19th-century Georgia and included many cultural as well as folk elements in his works. The following analysis of his stories about Uncle Remus focuses on (1) the levels of narration; (2) the linguistic complexity of the text (the stories abound in slang and dialectal expressions); (3) the form; and (4) the folklore value. These four aspects guide the discussion of the only Polish translation of the Uncle Remus stories. Prepared by Wladyslawa Wielinska in 1929, it was addressed to children. Therefore, the article aims to determine the profile of the translation as a children’s book, to consider it in relation to the skopos of the source text and to establish the extent to which it preserved the peculiar character of the Uncle Remus stories.
