(I) subjecting to a reduction treatment a catalyst comprising a carrier having provided thereon: 0.1 to 10% by mass of at least one metal selected from an alkali metal, an alkaline earth metal, a rare earth metal and the Group III in the periodic table and 1 to 30% by mass of ...
The biological function of Group IA and IIA cations of the periodic table is reviewed against the background of their chemistry. Utilization of these cations arises from an ability to form different types of complex compounds, which is dependent upon the radius-ratio effect. If the details of ...
While strictly anaerobic Bacteroides species from the Bacteroidia class are well-known members in gut microbiota of humans and animals, aerobic Flavobacteriia is the largest class found in a wide range of ecosystems [6]. The isolation of Flavobacterium species has been reported for soil and aquatic...
An aromatic polysulfone resin composition contains 100 parts by weight of an aromatic polysulfone resin and 0.001-50 parts by weight of at least one compound selected from oxides, peroxides, double oxides and carbonates of a metal belonging to the Group IA or IIA in the periodic table of ...
