After the new 1.1.00000 aero magnetic data were processed and the three-dimensional inversion work was carried out, a vast high magnetic body northwestward was discovered. The magnetic body is located at the depth of about 20 km on the west side of Tanlu fault and at about 25 km on the east side of Tanlu fault beneath the Sulu area. There is a difference of vertical distance of 3—5 km in depth between both sides. We think that the magnetic body is an Archean metamorphic plate and belongs to the North China block. The discovery of the magnetic body is significant for us to reconstruct the structure model of the Sulu orogenic belt, delineate the suture of collision between the North China block and the Yangtze block, and estimate the depth of slipping surface when the eastside of Tanlu fault moved northward.

Enhancing the therapeutic effect of existing treatments or developing new non-invasive treatments are important measures to achieve high-efficiency treatment of malignant *** therapy(PDT)is an emerging treatment modality,and the key for achieving high-efficiency PDT is to select light with strong tissue penetration depth and enhance the generation of reactive oxygen species(ROS).Although the upconversion nanoparticles(UCNPs)modified with the photosensitizers could achieve PDT with strong penetration depth under near-infrared light irradiation,the ROS generated by traditional single-pathway PDT is still ***,we developed a novel nanoconjugate(UCNP-Ce6/AIEgen)for dual-pathway reinforced PDT,in which the UCNPs were co-modified with chlorin e6(Ce6)and luminogen with aggregation-induced emission(AIEgen).Due to the presence of AIEgen,UCNP-Ce6/AIEgen could avoid aggregation-caused luminescence quenching in biological water environments and convert upconversion luminescence(UCL)of UCNPs to Ce6-activatable ***,under the irradiation of 808 nm laser,UCNP-Ce6/AIEgen can not only undergo direct lanthanide-triplet energy transfer to activate Ce6,but also convert the UCL of UCNPs to the light that can activate Ce6 through Fӧrster resonance energy transfer to generate more ROS,thus promoting tumor cell *** work broadens the applications of nanoconjugates of lanthanide-based inorganic materials and organic dyes,and provides a conception for reinforced PDT of tumors.

The reaction of palladium chloride with isovanillin semithiocarbazone (VSTC), CH3O(OH)C6H3CH=NNC(S)NH2, in a mixed solvent of ethanol, pyridine and water yielded the mononuclear palladium(Ⅱ) complex Pd[CH3O(O)C6H3CHNNC(S)NH2](C5H5N), and its single- crystal structure was determined by X-ray diffraction. The crystal belongs to triclinic, space group P with a = 7.71.(4), b = 9.809(6), c = 1..61.(4) ? a = 93.54(4), b = 1.1.00(3), g = 95.92(5), V = 745.0(7) 3, Mr = 408.75, Z = 2, Dc = 1.822 g/cm3, m = 1.397 mm-1. and F(000) = 408. The final R = 0.0568 and wR = 0.1.39 for 261. observed independent reflections with I ≥ 2.0s(I). It was revealed that the palladium atom is bound to a tridentate donor ligand and a pyridine in a planar square arrangement. The sulphur-nitrogen-oxygen donor of the Schiff-base ligand in the thiol form rather than the thione one is coordinated to the palladium atom via the mercapto sulphur, the b-nitrogen and the hydroxylate oxygen atoms.

Using ion beam biotechnology in combination with soil-less plant cultivation on artificial substratum (floating beds), the experiments were conducted with Ipomoea aquatica Forsk. Plants were attached to floating-beds which were placed on the surface of artificially nutrient-enriched tank water, in order to study the purification and remediation efficiency of ion beam-treated I. aquatica cultivars. The results show that N + ion beams with 25keV energy and dosages of 0, 2.6, 3.9, 5.2, 6.5, 7.8, 9.1.1. 1.N +(ions)/cm 2 affected I. aquatica dry seeds differently, with the dose of 3.9×1. 1.N + (ions)/cm 2 improving effectively the performance as expressed by various biological indices. After ion beam application, I. aquatica cultivars grew well in nutrient-enriched water bodies, increasing the growth of leaves and stem, number of leaves, length and area of roots, plant height, and weight more remarkably than observed in the control. The net removing rates of TN, TP were as high as 75% and 82%, respectively. Especially under the dose of 3.9×1. 1.N +(ions)/cm 2, the net removing rates of TN, TP were highest, for 77% and 85%, respectively. It was proved that ion beam application improves phytoremediation and may be used to purify nutrient rich water bodies.

稀土过渡族金属化合物是功能材料研究领域的重要对象。本文综述了CaCu5衍生型稀土过渡金属化合物Rn-mM5n+2m结构和变换关系的传统内容、含义,以及在应用中的有效性和局限性。从原子间相互作用势出发,通过能量最小化对5类二元本征结构SmFe5,Sm2Fe1.(H),Sm2Fe1.(R),SmFe1.(t),Sm3Fe29的空间群及晶格参数进行了计算,并由此确定了这5类结构间的变换矩阵,与传统矩阵变换关系作了对照,分析了它们相近和相异的原因。讨论了第三元素Cr,Ti对Sm3Fe29结构的稳定作用,以及对晶体几何参数及X光谱的影响,这都是传统矩阵变换反映不了的。
