  摘要：

  A convenient and practical method is proposed for the synthesis of lanthanide and yttrium alkoxides. The method involves dissolving the metals or their hydrides in a solution of dry HCl in the corresponding alcohol, with subsequent dehalogenation of the LnCl3 solution by an equivalent amount of alkali metal (Na, Li), The rare-earth alkoxides are easily converted into acetylacetonates Ln(acac)3 by the action of acetylacetone.

• A Universal Scheme for Patterning of Oxides via Thermal Nanoimprint Lithography

  Direct patterning of oxides using thermal nanoimprint lithography is performed using either the sol‐gel or methacrylate route. The sol‐gel method results in resists with long shelf‐life, but with high surface energy and a considerable amount of solvent that affects the quality of imprinting. The methacrylate route, which is limited to certain oxides, produces polymerizable resists, leading to low surface

  使用溶胶-凝胶法或甲基丙烯酸酯法，使用热纳米压印光刻技术直接对氧化物进行构图。溶胶-凝胶法可以使抗蚀剂具有较长的保存期限，但具有较高的表面能和大量溶剂，从而影响压印质量。仅限于某些氧化物的甲基丙烯酸酯途径可产生可聚合的抗蚀剂，导致表面能较低，但前体的货架期较短。通过将这两种途径中的良性元素结合在一起，证明了使用使醇盐与可聚合螯合剂（例如2-（甲基丙烯酰氧基）乙基乙酰乙酸酯（MAEAA））反应制得的前驱体，对氧化物进行直接热纳米压印的通用方法。MAEAA拥有β-酮酸酯，可形成对环境稳定的物质，具有长保存期限的螯合醇盐和甲基丙烯酸酯基团，为压印过程中与交联剂的原位共聚提供了反应性单体侧基。聚合会导致阳离子的捕获，表面能的降低，压印的增强，从而可以在1 cm×2 cm的图案区域上轻松清洁脱模，产率约为100％。压印的热处理会产生无定形/结晶的氧化物图案。两条路线之间的这种联盟使成功印记了包括Al在内的多种氧化物成为可能

  Superconducting oxide thin films of the YBa2Cu3Ox system have been prepared on zirconia (YSZ) substrates by sol–gel technique using metal alkoxide solution. Yttrium butoxide, barium methoxide and copper methoxide in a given atomic ratio were dissolved in a triethanolamine–methanol solution. Coating of the resultant solution, heating at 800 °C in air and annealing in an oxygen atmosphere resulted in

  BaZr_0.8Y_0.2O_3−δ densifies at 1200 °C on employing a combination of Ba excess, ZnO sintering additive and nanopowders prepared by a sol–gel route. The low densification temperature decreases grain-boundary resistance despite the lower grain size.

  Hydrolysis of a mixture of iron ethoxide and yttrium butoxide produced amorphous yttrium iron garnet (YIG) ultrafine particles with a mean diameter of 9 nm. The particles prepared by hot water vapor hydrolysis were less agglomerated than those prepared by plain hot water. DTA revealed that a broad phase transition temperature To from amorphous YIG to crystalline YIG ultrafine particles is 691°C with heat discharge of 118 kJ/mol which is attributed to the entropy decrease accompanying the crystallization, whereas magnetic experiments gave a value of To= 650°C. The particles calcined at 700°C were single‐crystalline ones while those calcined at higher temperatures (at least higher than 800°C) were multicrystalline ones.

  由铁的乙酸乙酯和钇的丁酸乙酯混合物水解生成平均粒径为9 纳米的无定形钇铁石榴石(YIG)超细颗粒。与单纯热水处理相比，热水蒸汽处理得到的颗粒团聚较少。DTA分析显示，从无定形YIG到晶态YIG超细颗粒的相变温度T_o约为691°C，伴随118 kJ/mol的放热，这归因于结晶过程中的熵减。然而，磁性实验测得的T_o值为650°C。700°C煅烧的颗粒为单晶，而800°C及以上煅烧的颗粒为多晶。

  The "124" phase (YBa2Cu4O8) is synthesized at a low temperature of 700-degrees-C in O2 gas flow (PO2 = 1 atm) by means of a sol-gel method using only alkoxides. The prepared Cu-butoxide for the present synthesis is soluble up to 36 mMol/l in butanol and hydrolyzable. The sample sintered at 760-degrees-C exhibits superconductivity with the zero-resistance temperature (Tc(R = 0)) at 78 K.
