The Design of DNA Nanomaterials and Their Applications in Biosensors and Protein Machines [PDF]
, 2016 DNA不仅是遗传信息的载体，同时还具有识别、催化和“建筑”等诸多功能，因而在生物传感、药物运输、蛋白质机器、纳米光子学等领域中得到了广泛的应用。然而，随着研究的深入，研究者们也遇到了一些新的挑战。其中，DNA纳米材料在生物传感和蛋白质机器方面的应用受到了以下限制： 分子信标、核酸适体等DNA纳米材料在生物传感器的设计方面具有独特的优势，因此得到了广泛的应用，但是仍然存在以下问题：（1）DNA纳米材料在细胞内的稳定性。细胞内含有核酸外切酶、核酸内切酶等各种各样的核酸酶，且数量巨大 ...

Stress related properties of GaN based semiconductor heterostructures [PDF]
, 2008 GaN基半导体作为光电子材料领域极为重要的材料，其异质结构在器件开发领域得到十分广泛的应用。本文通过实验研究和计算模拟，考察研究了GaN基半导体异质结构中界面和表面的应力相关特性。运用高分辨率x射线衍射技术获得了6周期AlxGa1-xN/GaN超晶格结构中的应变，层厚及组分信息。采用对界面和表面变化敏感的掠入射x射线反射谱技术和原子力显微镜表面形貌技术深入研究了该超晶格结构的界面和表面平整度与垒层组分及阱层宽度的关系。研究发现，低Al组分阱宽小的样品界面与表面的平整度最好 ...

Self-Cleaning Glass Antireflection Films Prepared by Sol-Gel Method [PDF]
, 2013 在酸催化体系中以正硅酸乙酯(TEOS)和纳米锐钛矿型二氧化钛粉末为SIO2-TIO2复合溶胶原料,采用提拉法在高硼硅玻璃基片表面制备出具有增透和自清洁功能的薄膜。研究了制备工艺对薄膜增透和光致超亲水性能的影响。制备的样品在400~800 nM波段,光线垂直入射时,透射率增加3%,紫外光照射一定时间后,样品对水接触角不超过5°,具有光致超亲水作用。The self-cleaning glass antireflection film was prepared on the surface of high ...

Preparation and Properties of Low Swelling Anion Exchange Membranes for Fuel Cells [PDF]
, 2017 与质子交换膜燃料电池(PEMFCs)相比，阴离子交换膜燃料电池(AEMFCs)因具有更高的电极反应活性、抗中毒能力和廉价的金属催化剂(如：镍、钴和银等)而备受关注。作为AEMFCs的核心组分，阴离子交换膜(AEMs)同时起着分隔阴阳极反应物和传导离子的作用。在AEMs中，OH-的传导方向是从阴极到阳极，与燃料渗透方向相反，因而可以有效避免燃料因电拖曳作用而发生渗透。即便如此，OH-在水中的相对迁移率远低于H+，导致AEMs的电导率很难达到质子交换膜的水平。为了解决该矛盾 ...
