β-diketones, 5-nonyl salicylaldoxime, and their mixture were used to extract copper from ammoniacal solution. The results showed that when the initial concentration of copper was 2.5 g/L, the concentration of ammonia was 56 g/L, and the volume ratio of β-diketones to 5-nonyl salicylaldoxime was 1:2, the copper recover…
The continuous cooling transformation (CCT) behaviour was investigated for the 0.2C-0.5Si-0.08P-Mn TRIP steel with 0.19% vanadium on a thermo-simulator. The results revealed that the starting transformation temperature of ferrite (A(subscript r3)) is increased by 42-58℃ during subsequently continuous cooling after the…

在微波辐射条件下，对共沉淀法制备合成甲醇CuO／ZnO／A1203催化剂前驱体的母液进行老化，通过改变Cu／Zn比，研究了微波辐射对催化剂性能的影响，并结合XRD，FTIR，DTG，H2-TPR，XPS等表征手段，探讨了微波辐射对前驱体物相组成及催化剂微观结构的影响．结果表明：在微波辐射老化条件下，Cu／Zn比对催化剂前驱体物相组成影响较大，微波辐射有利于绿铜锌矿（Cu，Zn）5（C03）2（0H）6晶相选择生成．当Cu／Zn比为2．0时，前驱体中含有较多的绿铜锌矿物相，且结晶较好，焙烧后形成的催化剂中CuO—ZnO协同作用较强，CuO分散性好，导致H：还原温度低，在浆态床合成甲醇过程中表现出良好的催化活性和稳定性，甲醇时空收率（…
采用固相反应法制备了双钙钛矿Sr2Mn1-xGaxMoO6（x=0．0～1．0）掺杂化合物。室温下的高分辨率X射线衍射分析表明，Sr2MnMoO6具有单斜晶体结构，空间群为P21／n。Ga的掺杂没有改变化合物的晶体结构，但衍射峰整体向高角度漂移。结构精修分析表明，Sr2Mn1-xGaxMoO6样品的晶胞体积随Ga含量的增加而逐渐减小；B／B’位离子占位有序度伴随Ga的掺入而逐渐降低；此外，Ga的引入导致〈B—O〉键长的缩短，〈B’-O〉键长的伸长。

Temperature-dependent, in-plane, thermoelectric power (TEP) data are presented for Ba(Fe1-xRux)2As2 (0 < x < 0.36) single crystals. The previously outlined x - T phase diagram for this system is confirmed. The analysis of TEP evolution with Ru-doping suggests significant changes in the electronic structure, correlatio…
Abstract ZnO is an excellent material candidate for ultraviolet (UV)‐light emitting devices based on its exciton emission. We have applied solution‐processed ZnO NCs to printed electroluminescence (EL) devices as their emission layers (EMLs) to develop a novel flexible lightweight, and flat‐panel UV‐light source. In t…

Malignancy, subglottic stenosis and traumatic injury to the trachea require surgical resection. When short segments are involved, primary re-anastomosis affords excellent results. Longer lesions, involving more than half of the tracheal length in adults or one third of the tracheal length in children, require novel so…
Typographical errors appeared in the original publication. These errors do not change the functionality of the algorithm and they are reasonably obvious when implementing the method. Nevertheless, we wish to present the correct equations for completeness. The equations in question are: The authors are grateful to Yota…
In the monomeric title compound, [Cu(C(4)H(4)O(5))(C(6)H(6)N(2)O)(H(2)O)]·1.5H(2)O, the Cu(II) cation is bound in a square-pyramidal coordination to a tridentate oxydiacetate (ODA) ligand, a monodentate pyridine-3-carboxamide (p3ca) ligand and one aqua ligand, where the two organic ligands form the basal plane and the…
This chapter provides an overview of some recent advances in metamaterial antennas and radiative systems. It presents the fundamental theory of the metamaterials, including resonant particle (RP) and transmission line (TL) metamaterials, and their relation. The chapter deals with leaky-wave and resonant metamaterial a…

DIAMOND NANOPARTICLES can catalyze a major industrial reaction more eff ectively and under simpler conditions than the standard commercial transition-metal-based catalyst typically used for that process, according to an international team of researchers ( Angew. Chem. Int. Ed., DOI: 10.1002/anie.201002869). The study…
