Genetic improvement for phosphorus efficiency in soybean: a radical approach
Background Low phosphorus (P) availability is a major constraint to soybean growth and production. Developing P-efficient soybean varieties that can efficiently utilize native P and added P in the soils would be a sustainable and economical approach to soybean production. Scope This review summarizes the possible mechanisms for P efficiency and genetic strategies to improve P efficiency in s…

Effect of La2O3 on Ru/CeO2-La2O3 Catalyst for Ammonia Synthesis
Abstract A series of CeO2-La2O3 supported ruthenium catalysts were prepared by co-precipitation method and the as-obtained samples were characterized by N2 physisorption, X-ray diffraction, CO chemisorption, H2-TPR, H2- TPD and XPS. The activity test shows that ammonia concentration of the catalyst with 10% La is 13.9% at 10 MPa, 10,000 h-1, 450 C, which is 17% higher than that of Ru/CeO2…
