Abstract:
Abstract Phase relationships in the Ce-Nd-B ternary system at 773 K were investigated by means of X-ray diffraction and scanning electron microscopy with energy dispersive X-ray spectroscopy techniques. Six borides, i. e. CeB4, CeB6, NdB4, NdB6, NdB66 and Nd2B5 are confirmed in this work. No ternary compound was observed. CeB4 and NdB4 were discovered to form the continuous solid solution phase (Ce,Nd)B4, CeB6 and NdB6 also form the solid solution phase (Ce,Nd)B6. The maximum solid solubility of Ce in (Ce,Nd)2B5 phase is 46.5 at.%. The isothermal section of the Ce-Nd-B ternary system at 773 K consists of 3 three-phase regions, 7 two-phase regions and 7 single- phase regions.

Abstract:
ABSTRACT Streptomyces reticuli has an inducible ATP-dependent uptake system specific for cellobiose and cellotriose. By reversed genetics a gene cluster encoding components of a binding protein-dependent cellobiose and cellotriose ABC transporter was cloned and sequenced. The deduced gene products comprise a regulatory protein (CebR), a cellobiose binding lipoprotein (CebE), two integral membrane proteins (CebF and CebG), and the NH2-terminal part of an intracellular β-glucosidase (BglC). The gene for the ATP binding protein MsiK is not linked to the ceb operon. We have shown earlier that MsiK is part of two different ABC transport systems, one for maltose and one for cellobiose and cellotriose, in S. reticuli and Streptomyces lividans. Transcription of polycistronic cebEFG and bglC mRNAs is induced by cellobiose, whereas the cebR gene is transcribed independently. Immunological experiments showed that CebE is synthesized during growth with cellobiose and that MsiK is produced in the presence of several sugars at high or moderate levels. The described ABC transporter is the first one of its kind and is the only specific cellobiose/cellotriose uptake system of S. reticuli, since insertional inactivation of the cebEgene prevents high-affinity uptake of cellobiose.

Abstract:
B4C-CeB6 porous composites are prepared by hot pressed sintering between 1900°C and 2000°C, and mechanical properties and phase composition of B4C-CeB6 porous composites were tested. The results show that the porous rate of B4C-CeB6 porous composites ranges between 30%-48% at sintering temperate 1900°C-2000°C. Porous rate of B4C-CeB6 porous composites is decreased with temperature be increased. Flexibility strength of B4C-CeB6 porous composites is greatly improved compared with that of monolithic porous boron carbide. B4C react with CeO2 to completely form CeB6 in porous composites.

Abstract:
B4C-CeB6/Al composite was fabricated by pressureless infiltration technology. It is composed of the phases of Al, B4C, AlB2, Al3BC and CeB6, and Al4C3 is not found because of the existence of CeB6. It could identify that AlB2, CeB6, and Al3BC were formed as interfacial reaction products. Al3BC is formed on the interface of B4C and Al; therefore it connects the aluminum with the ceramic toughly. AlB2 as strip crystal is formed between B4C and Al, which has higher fracture toughness.CeB6 particles in B4C grain boundary are discovered by TEM, which caused intercrystalline rupture. Grain toughening and reinforcing, crack deflection, crack bridging is the main toughening and reinforcing mechanisms of B4C-CeB6/Al composites.

The results show that Flexibility strength of B4C-CeB6 porous composites is greatly improved compared with that of monolithic porous boron carbide. B4C react with CeO2 to completely form CeB6 in porous composites. CeB6 particles in B4C grain boundary are produced by in-situ reaction. The presence of CeB6 reinforcing particles could also suppress growth of B4C grains which normally leads to improved strength.

Abstract:
High-purity and homogeneous powders of CeB6 with nanometer size were prepared by combustion synthesis and subsequent acid- leaching. The effects of reactant ratio on the phase and morphology of the combustion product were discussed. The combustion product and leached product were analyzed by XRD, SEM and EDS. The results indicate that the combustion product consists of CeB6, MgO and Mg3B2O6. The combustion products are denser and less layered when the Mg content and KClO3 content increase. The content of CeB6 in the combustion product could be enhanced with increasing the excessive content of Mg. The purity of CeB6 is higher than 99.0% and its particles are smaller than 150nm.
