声表面波(SAW)技术广泛应用于无线通信、传感器、微流体、光子与量子信息通信等领域。然而,受限于制造技术的发展,SAW器件的频率通常在几个吉赫(GHz)以内,严重限制了SAW器件在5G通信、高精度传感、光子与量子控制中的应用。针对上述关键问题,本文提出将极端纳米制造技术与LiNbO3/SiO2/SiC异质结构衬底相结合的策略,成功制备出波长为160 nm的超高频SAW器件,其高阶模态谐振频率高达约44 GHz,获得的机电耦合系数高达15.7%。基于LiNbO3/SiO2/SiC 异质结构衬底的超高频SAW呈现出多种模态,理论仿真分析确定了高阶声波模态的波模态。进行了超高频SAW微质量传感应用研究,其最高质量灵敏度高达33151.9 MHz⋅mm2⋅μg−1,比频率为978 MHz的传统SAW器件质量灵敏度高4000 倍,是传统石英微天平(QCM)器件质量灵敏度的1011倍。

DNA不仅是生命遗传信息的载体,而且是一种高度可编程和自组装的纳米材料。不同的DNA结构与其生物学和化学功能有关。因此,了解各种DNA结构的物理和化学性质在生物学和纳米化学中具有重要意义。然而,群体分子实验忽略了溶液中DNA结构的异质性。单分子分析方法是观察单个分子的行为和探测自由能态的高异质性的有力工具。本文介绍了单分子检测和操纵等单分子分析方法,并讨论了这些方法如何用于测量单/双链DNA(ss/dsDNA)、DNA高阶结构和DNA纳米结构的分子性质。最后,将DNA纳米技术和单分子分析方法进行结合以了解DNA和其他生物物质、软物质的生物物理特性。

Fruit cracking is a major disorder that affects the integrity of fruit and reduces the commercial value of tomato and other fleshy fruit. Here, we have found a novel fruit ‘netted-cracking’ (FNC) phenotype in tomato introgression line IL4-4 which is present in neither the donor parent (LA0716) nor the receptor parent (M82). An F2 population was generated by crossing IL4-4 with M82 to genetically characterize the FNC gene and this showed that a single dominant gene determined fruit netted-cracking. Further map-based cloning narrowed down the FNC locus to a 230 kb region on chromosome 4. Sequencing and annotation analysis show that FNC(Solyc04 g082540) was the most likely candidate gene. Functional characterization of FNC by overexpressing FNCAC and FNCIL4-4resulted in the fruit netted-cracking phenotype, suggesting that the FNC transcript level results in the functional gain of fruit netted-cracking. These findings were further confirmed by FNC ortholog in netted-cracking pepper and melon, indicating a common regulatory mechanism in different plant species. Furthermore, cytoplasm and nucleus-localized FNC indicates increased expression of genes involved in suberin, lignin, lipid transport and cell wall metabolism. These findings provide novel genetic insights into fruit netted-cracking and offer a way to promote molecular improvement toward cracking resistant cultivars.

For assemble-to-order enterprises, both order scheduling and mixed-model sequencing need to be taken into consideration in the formulation of order-oriented assembly plan. First, determining production priority for the received orders, and then conducting assembly sequence to the mixed-model products in each order. Order scheduling is aimed to ensure order delivery with the optimization goal of minimal total overdue time, while product sequencing is aimed to minimize the makespan so as to meet the requirement on completion time of the order. In the end, the paper establishes a mixed integer programming model based on an industrial case, and makes programming calculation with Xpress-MP to accomplish an order-oriented assembly plan conforming to actual production.
