金纳米粒子表面修饰剂的组分和形貌影响其物理化学性质.本文采用隐式溶剂耗散粒子动力学模拟的方法,研究了金纳米棒、溴化十六烷基三甲基铵和二肉豆蔻酰磷脂酰胆碱的自组装形貌.结果表明,复合体组装形貌主要与溴化十六烷基三甲基铵和二肉豆蔻酰磷脂酰胆碱这两种修饰剂的摩尔比有关,而金纳米棒与修饰剂的相互作用强度以及金纳米棒的直径对形貌的影响不明显.当作用强度和直径一定时,随着摩尔比增加,修饰剂在金纳米棒表面会形成完整的双层膜、有裂痕的双层膜、长片状胶束、以及以螺旋形式缠绕在金纳米棒上的蠕虫状胶束.进一步分析发现,金纳米棒直径越小、摩尔比越大、或作用强度越大时,金纳米棒两端的覆盖程度越高,同时修饰剂吸附层的厚度越薄.这些结果直接表征了溴化十六烷基三甲基铵和二肉豆蔻酰磷脂酰胆碱混合物在金纳米棒表面的形态,在分子水平上加深了对金纳米棒自组装行为的理解,有助于实现金纳米棒的可控自组装.

Pronounced impact of size and shape effects on creep rupture life of a K439B superalloy combustion chamber casting simulator

引用

China Foundry 2025年

作者： Wen-tong Liu Yi-dong Wu Lei gao Jing-yang Chen Cheng-bo Xiao Xi-dong hui State Key Laboratory for Advanced Metals and Materials University of Science and Technology Beijing Science and Technology on Advanced High Temperature Structural Materials Laboratory Beijing Institute of Aeronautical Materials

The size and shape effect(SSE) of components has become a critical issue for mechanical properties, application reliability, and processing. In this study, the creep rupture life(CRL) of components with different wall thicknesses and positions in a combustion chamber casing simulator made of K439B superalloy was investigated. The intrinsic mechanisms of the SSE were explored from the dendrite structure, volume fraction and size of the γ' phase, and element segregation, etc. It is shown that this casting exhibits a strong SSE of creep rupture life, characterized by a significant difference in the CRL values up to 60% with the variation of wall thickness and position in the casing. In terms of casting technology, the influence of SSE on CRL is actually determined by the cooling rate. The SSE on the creep rupture life originates from the dendrite structure(such as the secondary dendrite arm spacing), volume fraction size of the γ' phase in the dendrite trunk, and elements segregation rate. This work may have implications for the design and application of engineering components with large sizes and complex structures.

探讨A型肉毒毒素治疗面肌痉挛方法改良后疗效。随机将我院神经内科肌痉挛专科门诊56例面肌痉挛的患者分为A、B两组,A组26例用传统的单侧肉毒毒素注射治疗,B组30例采用改良的双侧选择性肉毒毒素注射治疗。观察A型肉毒毒素注射治疗后口角两侧不对称和眉毛下垂不对称的发生情况。统计采用SPSS 19.0软件包进行检验。B组治疗后产生口角两侧不对称和眉毛下垂不对称明显低于A组,两组发生例数的比较有统计学意义(P<0.05)。同时,发现患者的满意度两组间也有统计学意义(P<0.05)。本研究发现采用改良的双侧选择性肉毒毒素注射治疗较传统的单侧肉毒毒素注射治疗面肌痉挛能明显地减少口角两侧不对称和眉毛下垂的发生。

器官移植被认为是治疗终末期器官衰竭、早期恶性肿瘤及组织损害的有效方法。为了减轻宿主对移植器官的排异反应,需长期使用免疫抑制药物,但免疫抑制剂对宿主免疫系统的抑制会引起严重的副作用。因此对于如何在移植后,诱导受体的免疫系统对移植器官产生无应答状态,而对异己抗原仍然能表现出正常的免疫应答,即诱导受体对供者器官产生特异的免疫耐受是移植科学家长期以来致力研究的热点。可溶性CD83(sCD83)是一种具有特异性免疫抑制作用的糖蛋白。近年来,在动物实验中有关sCD83诱导受体中移植器官产生免疫耐受的报道越来越多,这为其在治疗器官移植后的宿主免疫排斥方面展现了广阔的前景,更为其临床转化提供了实验基础。

为了评价和改善坛子网的作业性能,本文在网囊前端安装由方形网目网片(网目尺寸分别为35、40、45和50mm)和刚性框架(长80cm,宽60cm)所组成的方形网目逃逸窗装置来释放幼鱼,并利用套网法在海州湾海域开展海上试验。在分析渔获的基础上,运用相对重要性指数、logistic模型等分析方法,获得了坛子网渔获物种类组成、优势种和主要经济渔获物小黄鱼(Larimichthys polyactis)和鹰爪虾(Trachypenaeus curvirostris)的选择性曲线。研究显示,随着逃逸窗网目尺寸增大,小黄鱼、鹰爪虾的50%选择体长(L50)逐渐增大,且L50的值与逃逸窗网目尺寸呈线性关系;逃逸窗网目尺寸为35、40、45和50mm时,小黄鱼的L50分别为9.27、12.54、13.46和15.94cm,鹰爪虾的L50分别为5.31、6.35、7.73和8.66cm。根据试验结果,结合小黄鱼的最小可捕体长及鹰爪虾第一次性成熟体长,推算小黄鱼和鹰爪虾坛子网方形网目逃逸窗网目尺寸分别为47.7和36.3mm。研究结果可为我国海州湾海区渔具管理以及渔业资源的可持续发展与管理提供技术依据。
