在 nanoscience 以内的 actinide 社区的主要目的之一开发好理解类似于当前是为稳定的元素的盒子的。作为后果，有效、可靠、万用的合成技术奉献了给新基于 actinide 的 nano 反对的形成(例如 nanocrystals ) 是必要的。因此，奉献给各种各样的 actinidebased nanoscale 积木的准备的一个图书馆当前正在被开发。有悦耳的尺寸，形状和作文的 Nanoscale 积木具有主要重要性。到目前为止，在高度协调器官的媒介的非水的合成方法是表明了能力提供基于 actinide 的 nanocrystals 的尺寸和形状控制的唯一的途径(为钍和铀，并且最近延长了到镎和钚) 。在这份报纸，我们…
这份报纸用多层的亚波长建议了一个新奇宽带过滤器高对比的栅栏(HCG ) 结构。这个过滤器有宽带宽和好边带抑制。我们在过滤宽带过滤器的性能上模仿了并且分析层和不同栅栏索引的不同数字的效果。根据模仿的结果，我们设计了一个多层的 HCG 宽带过滤器，它有 843 nm 的带宽和 1550 nm 的中心波长。
The purpose of this study was to evaluate the applicability of several current approaches used to estimate losses in prestressed concrete members with compressive strengths greater than 15ksi. The scope of the study focused on time-dependent losses for normal weight concrete bonded applications. The approaches evaluat…
How to defeat the conflict of strength vs toughness and achieve unprecedented levels of damage tolerance within structural materials is a great challenge for designing microstructure-sensitive materials. The nanostructured metallic multilayers(NMMs) are widely used as essential components of high performance microelec…
因为它的突出的角色，纤维蛋白原的吸附能在凝结和血小板粘附被用作表面 haemocompatibility 的快指示物。在这个工作，在纤维蛋白原和一块修改的钛氧化物表面 / 血小板之间的分子的相互作用被石英水晶微量天秤在 situ 与驱散(QCM-D ) 学习了。为了进一步描绘吸附的纤维蛋白原， C 和链抗体的符合构造，被用来检查固体上的纤维蛋白原的取向和变性作用出现。QCM-D 调查揭示了纤维蛋白原有趋势由断然控告的 C 领域在站在一起上取向在吸水的表面上吸附，它将在链上减少血小板结合地点的暴露并且启用更少的血小板粘附并且被激活。这些观察建议吸附的纤维蛋白原的某些符合构造比其它是更少的血小板粘合剂，它为创造非血小板粘合剂打开可能性…
