1采用溶剂热技术通过置换反应在300-350℃合成了20nm的CrN纳米晶，与传统固相制备法相比，大大降低了反应和结晶温度；在180℃合成了磷化钴纳米粉，XRD显示两相共存(C0〓P、CoP)，TEM中也证实两种形貌的存在；该技术成功的解决了前驱物易水解的问题。

Three activated carbons having different surface areas, coconut-shell based, pelletized and bamboo-derived, were modified by mixing them with four thermoplastic precursors, poly, hydroxy propyl cellulose, citric acid, and fluorine-containing polyimide followed by heat treatment at 900℃ for 1h.

三种具有不同比表面积的活性炭—椰壳基AC-C、粒状AC-P和竹基AC-B分别与四种热塑性前驱体—聚乙烯醇，羟基丙基纤维素，柠檬酸，含氟聚酰亚氨混合后，在900℃热处理1h。

The front elbows and pasterns should not flip in or out as this can be a big energy waster, and cause instability.

前驱肘关节和踝关节不应该向内或向外，因为那样会造成能量的浪费，而且引起不安定。

Pasterns show flexibility with a slight slope when viewed from the side.

从侧面看前驱与背线的过度阶段衔接适度。

Then the surface of the star polymer was intramolecularly crosslinked using octa(3-azidopropyl)polyhedral oligomeric silsesquioxane, POSS-(N_3)_8,as the inorganic multifunctional crosslinker at high dilution concentration via click chemistry,forming a novel POSS/polymer hybrid nanostructure.Thermogravimetric analysis shows that after surface crosslinking, the thermostability of the core crosslinked PS can be remarkably improved.In the second work,we synthesized of a novel polymer with quatrefoil-shaped topology.

接着，我们合成了一种结构规整的含八个叠氮功能团的无机分子—多面低聚倍半硅氧烷，以其为交联剂，我们通过Click反应在即稀浓度下实现了前驱体星型聚合物的分子内表面交联，得到了外层为无机分子交联，内层为有机高分子的星状高分子，这种新型的星状聚合物表现出了优良的热稳定性能。

The method takes an ethanol suspension of monocrystal tungsten trioxide (WO3) nano-plates as a precursor, and utilizes the habit that the nano-plate with high diameter-thickness ratio tends to be parallel to a substrate and the principle that solvent volatilization causes the oriented self-assembly of the nano-plate to prepare the tungsten oxide (WO3) nano film which is formed by overlapping the tungsten trioxide (WO3) nano-plates and oriented along the [002] crystallographic direction.

本发明涉及一种取向氧化钨纳米薄膜的制备方法，该方法以单晶三氧化钨(WO 3 )纳米片的乙醇悬浮液为前驱物，利用高径厚比的纳米片趋向平趟于基底的习性，以及溶剂挥发诱发纳米片取向自组装的原理，制得由三氧化钨(WO 3 )纳米片叠加而成的沿[002]晶向取向的三氧化钨(WO 3 )纳米薄膜。
