  Specifics of reactions of cerium sulfate and europium sulfate with hydrogen

  摘要：

  Reactions of cerium sulfate and europium sulfate with hydrogen have been studied. Diagrams showing the evolution of phase composition of the polycrystalline products of reaction between europium sulfate and hydrogen are constructed. The reaction of Ce-2(SO4)(3) with hydrogen at 600A degrees D consecutively yields Ce2O2S and Ce2O3 phases. At 800A degrees D the batch is > 95 mol % Ce2O3. At 480-500A degrees D, a single-phase sample of EuSO4 is prepared; at 600-1000A degrees D, Eu2O2S is prepared; and at 1050A degrees D, the batch is > 95 mol % Eu2O2S and up to 5 mol % Eu2O3. Atomic-force microscopy shows that europium sulfate grains, which represent agglomerates of particles 10-20 mu m in size, are degraded upon reaction with hydrogen into individual ovalshaped particles sized 40-60 x 130-200 nm.

  Synthesis, structure and properties of lanthanide dithionates and their triphenylphosphine oxide complexes

  摘要：

  The synthesis and properties of representative lanthanide dithionates are described and their potential use as catalysts discussed on the basis of dissociation of the coordinated dithionate in the presence of phosphoryl ligands. Complex formation with triphenylphosphine oxide has been studied and a number of complexes isolated. The infrared spectra of all compounds indicate coordination of the dithionate ion to the metal. The X-ray structures of Nd-2(S2O6)(3) . 14H(2)O (R1=0.0209 for 3368 diffractometer observed reflections) and Nd-2(S2O6)(3)- (Ph3PO)(4) . 8H(2)O (R1 = 0.1088 for 5406 diffractometer observed reflections) confirm the coordination of the dithionate with one previously unreported coordination mode, and show a polymeric structure for Nd-2(S2O6)(3) . 14H(2)O whilst Nd-2(S2O6)(3)(Ph3PO)(4) . 8H(2)O is a hydrogen bonded dimer.

  Cerium oxide nanoparticles (CNPs) have been proven to exhibit antioxidant properties attributed to its surface oxidation states (Ce4+ to Ce3+ and vice versa) mediated at the oxygen vacancies on the surface of CNPs. Different anions in precursor cerium salts were used to prepare CNPs resulting in disclosed CNPs with varying physicochemical properties such as dispersion stability, hydrodynamic size, and the signature surface chemistry. The antioxidant catalytic activity and oxidation potentials of different CNPs have been significantly altered with the change of anions in the precursor salts. For one, CNPs prepared using precursor salts containing NO 3 − and Cl − ions exhibited increased antioxidant activity than previously thought possible. The change in oxidation potentials of CNPs with the change in concentration of the nitrate and chloride ions indicates the disclosed CNP's have different surface chemistry and antioxidant properties. These compositions and methods of their synthesis are disclosed.

  investigations of three actinide(IV) 4-phosphoryl 1H-pyrazol-5-olate complexes (An = Th(IV), U(IV), Np(IV)) and their cerium(IV) analogue display the same metal coordination in the solid state. The mononuclear complexes show the metal centre in a square antiprismatic coordination geometry composed by the two O-donor atoms of four deprotonated ligands. Detailed solid state analysis of the U(IV) complex shows that

  恐怖袭击最常见的情况是隐藏或掩埋炸药。因此，爆炸性蒸气检测是至关重要的。炸药是缺乏电子的材料；爆炸物附近的荧光物质会遇到电子迁移。这项研究报告了具有独有光学性质的铈（III）-三聚氰胺配位聚合物（CeM-CP）的简便合成。CeM-CP在385 nm的100 mW功率的UVA LED光源刺激下，在可见光和红外波段显示出新颖的光谱荧光特性。受刺激的CeM-CP在400、700和785 nm处显示出独特的光谱荧光信号。这些荧光信号与铈与四个氮原子的配位相关。空轨道将可用于电子激发迁移。当CeM-CP经受TNT蒸气时，光谱荧光信号被淬灭。高光谱成像提供了3D荧光标记图。主要结果是在785 nm处实现了完全的荧光信号衰减。CeM-CP可用作爆炸性蒸气检测的新型传感元件。
