Transcriptome and QTL analyses reveal candidate genes for fiber quality in Upland cotton

中国第四届静电纺丝大会(CICE2016)

作者： huan Zeng Ning Cai chao Han Jing fu Faquan Yu Wuhan Institute of Technology

The ideal wound dressings should be multi-functional: fighting against acute or chronic infection;maintaining a balanced moisture and gas exchange environment;absorbing extrudates and blood from wounds;and promoting cell proliferation and migration and, thus, wound healing[1]. The antibacterial substances, such as Ag nanoparticles, iodine, and mupirocin, have been added to nanofiber dressings to eliminate infections[2]. Growth factors, vitamins, and minerals, as active compounds in wound healing, have been incorporated into nanofibers to promote normal skin growth and to reduce scar tissue formation[3]. In order to solve the problem of poor antibacterial properties and insufficient mechanical properties of the chitosan/gelatin（CG） nanofibers,we addressed a method for enhancing the antibacterial properties and mechanical properties of CG simultaneously by the addition of graphene oxide-silver（GO-Ag NPs） nanocomposite. Through the method, GO-Ag/CG nanofibers can be obtained successfully via electrospinning.

为了研究炸药燃烧产物驱动基体中裂纹动态扩展的耦合特性,加深对武器装药意外点火后反应进入裂纹形成对流燃烧引发高烈度反应的机理性认识,采用热点火方式对某奥克托今(HMX)基(质量分数为95%)高聚物粘结炸药PBX预置缺口点火,采用数字高速摄影技术对炸药燃烧产物驱动裂纹动态扩展过程开展了实验研究。结果表明,由于高聚物粘结炸药(PBX)存在较强的细观非均匀性,同一种炸药的不同样品细观结构也不完全相同,导致其裂纹扩展路径存在差异(可能沿直线传播,也可能会发生偏转),但是在相同的约束条件和预应力下其扩展速度基本一致,本研究实验条件下,该PBX炸药裂纹扩展平均速度为146.7m·s^-1。

A theoretical model of phase change heat sink was established in terms of thermal resistance network. The influence of different parameters on the thermal resistance was analyzed and the crucial impact factors were determined. Subsequently, the forming methods including ploughing-extrusion and stamping method of boiling enhancement structure at evaporation surface were investigated, upon which three-dimensional microgroove structure was fabricated to improve the efficiency of evaporation. Moreover, the crucial parameters related to the fabrication of miniaturized phase change heat sink were optimized. The heat transfer performance of the heat sink was tested. Results show that the developed phase change heat sink has excellent heat transfer performance and is suitable for high power LED applications.
