面对当前信息量爆炸式增长的现状,基于单晶硅的传统存储设备已经不足以满足信息存储的需求。同时,基于小型化和可穿戴电子设备的追求也引起了全球研究人员和相关从业人员的关注。研究人员不断努力寻求更为新颖的方法,以设计具有更高密度存储特征的柔性设备（如微穿戴设备等）来满足人们更高的需求。基于三元有机电子材料的微穿戴设备因具有多组分存储和可用于柔性基底的特征,因而为上述问题提供了最佳的解决方案。在本论文中,我们试图设计并合成一种新型的具有给受体交替结构的聚硅氧烷材料,命名为 PBSePA-alt-PTPAMSi,其中 5-（7-溴苯并[c][1,2,5]硒二唑-4-基）-N,N-二乙基嘧啶-2-胺（BSePA）和N-（4-（二乙氧基）（甲基甲硅烷基）苯基）-N-苯基苯甲胺硅氧烷（PTPAMSi）分别用作电子受体和给体部分。基于PBSePA-alt-PTPAMSi的柔性电存储器件将采用三明治结构制造,并且所获得的存储器件有望显示出典型的非易失性的一次写入多次读取（WORM）的三元存储器特性。由文献可知,基于BSePA类似物的5-（7-溴苯并[c][1,2,5]噻二唑-4-基）-N,N-二乙基-嘧啶-2-胺和PBTPASi的硅氧烷共聚物可以实现典型的非易失性WORM器件,因此我们得到的聚合物和器件也有希望可以用作典型的非易失性WORM存储器件。此外,我们还设计合成了 4,7-二溴苯并[c][1,2,5]噁二唑（BOPA）。之后,将通过Heck反应获得相应的硅氧烷化合物。最后,设计合成一个电子给体和两个电子受体的聚硅氧烷（PBOPASi）;而其记忆器件也将希望为我们提供三元WORM型记忆行为。

Helicobacter pylori (H. pylori) infection is one of the most common infections in human beings worldwide. H. pylori express lipopolysaccharides and flagellin that do not activate efficiently Toll-like receptors and express dedicated effectors, such as γ-glutamyl transpeptidase, vacuolating cytotoxin (vacA), arginase, that actively induce tolerogenic signals. In this perspective, H. pylori can be considered as a commensal bacteria belonging to the stomach microbiota. However, when present in the stomach, H. pylori reduce the overall diversity of the gastric microbiota and promote gastric inflammation by inducing Nod1-dependent pro-inflammatory program and by activating neutrophils through the production of a neutrophil activating protein. The maintenance of a chronic inflammation in the gastric mucosa and the direct action of virulence factors (vacA and cytotoxin-associated gene A) confer pro-carcinogenic activities to H. pylori. Hence, H. pylori cannot be considered as symbiotic bacteria but rather as part of the pathobiont. The development of a H. pylori vaccine will bring health benefits for individuals infected with antibiotic resistant H. pylori strains and population of underdeveloped countries.

电活性聚合物因其在柔性电子学中的应用而受到广泛关注。聚偏氟乙烯（PVDF）是一种卓越的电活性聚合物,其出色的电学性能归功于其多晶型特性。PVDF的极性相,特别是β、γ和δ相,具有卓越的压电、热电和铁电性能。因此,制备具有高含量极性相的薄膜至关重要。本研究的主要目标是通过两个不同的研究全面探索PVDF的多晶型行为和结晶动力学:在第一部分研究中,我们通过溶液浇铸法制备了PVDF均聚物薄膜。随后,利用自成核（SN）技术对这些薄膜进行特定的热处理,以探讨溶液浇铸的PVDF均聚物薄膜的相变行为和熔体记忆效应。傅立叶变换红外光谱（FTIR）和广角X射线衍射（WAXD）的结果表明,将样品在不同的自成核温度（T）热处理后会促进或α相或γ相的PVDF晶体形成。此外,差示扫描量热法（DSC）测试证实了均聚PVDF薄膜的熔融存在三个不同特征的温度区域。值得注意的是,Domain II（DII）区域被确定为α相到γ相转变的主要区域。该转变发生在DII区域所在的175°C到189°C的温度范围内,并在T=183°C处达到其峰值,其中在子区域DIIa内γ相含量达到95%。在第二部分中,我们深入研究了叔丁基丙烯酸酯（t-BA）链段区块的引入对于聚偏氟乙烯/聚叔丁基丙烯酸酯嵌段共聚物（PVDF-b-Pt BA）的结晶动力学和熔体记忆效应的影响。我们采用自成核技术分析了具有1臂和2臂线性共聚物及具有3臂和4臂的星型共聚物,并与PVDF均聚物进行了比较。结合DSC、FTIR和WAXD的结果分析表明,在线性聚合物中,形成γ相晶体含量最高时对应的自成核温度(T)随着t-BA臂的增加而降低,从均聚物的183°C,到1臂共聚物的179°C,再到2臂共聚物的177°C。相反,在3臂和4臂的星型共聚物中,T保持在177°C。值得注意的是,均聚PVDF样品在183°C热处理后仅能达到95%的γ相含量,而3臂星形共聚物在177°C到181°C的宽温度范围内展现出100%的γ相含量。此外,观察到在线性和星形聚合物中,t-BA链段区块的增加会显著减弱熔体记忆效应,并使γ相含量有所降低。这些发现为设计和控制聚合物材料的晶体结构提供了有价值的视角,进而为聚合物材料在不同领域的潜在应用提供了可能性。

TiO2 thin films are obtained by dc reactive magnetron sputtering. A target of titanium （99.995%） and a mixture of argon and oxygen gases are used to deposit TiO2 films on to silicon wafers （100）. The crystalline structure of deposited and annealed film are deduced by variable-angle spectroscopic ellipsometry （VASE） and supported by x-ray diffractometry. The optical properties of the films are examined by VASE. Measurements of ellipsometry are performed in the spectral range O. 72-3.55 e V at incident angle 75^o. Several SE models, categorized by physical and optical models, are proposed based on the ＇simpler better＇ rule and curve-fits, which are generated and compared to the experimental data using the regression analysis. It has been found that the triple-layer physical model together with the Cody-Lorentz dispersion model offer the most convincing result. The as-deposited films are found to be inhomogeneous and amorphous, whereas the annealed films present the phase transition to anatase and rutile structures. The refractive index of TiO2 thin films increases with annealing temperature. A more detailed analysis further reveals that thickness of the top sub-layer increases, whereas the region of the bottom amorphous sub-layer shrinks when the films are annealed at 300℃.
