| 1 | Global Well-Posedness of Solutions for the Sixth Order Convective Cahn-Hilliard Equation显示文摘In this paper,we consider the global well-posedness of smooth solutions for the Cauchy problem of a sixth order convective Cahn-Hilliard equation with small initial data.We first construct a local smooth solution,then by combining some a priori estimates,continuity argument,the local smooth solution is extended step by step to all t>0 provided that the L1 norm of initial data is suitably small and the smooth nonlinear functions f(u)and g(u)satisfy certain local growth conditions at some fixed point■. | Xiaopeng ZHAO Fengnan LIU Haichao MENG | 2021 | Journal of Mathematical Research with Applications2021，41，2： | 1 |
| 2 | Spatial differences of exergy use of cement manufacturing industry in China based on extended exergy accounting method显示文摘从 23 个省的工厂级的数据和在在 2012 生产工业和 socio 经济的水泥的一些国家统计数据被用来为由扩大 Exergy 财务方法生产工业的瓷器水泥分析 exergy 使用的空间分发。这个方法拿精力和原料供应和另外的外部因素(资本,劳动和环境) 的包括的完整的报道进一个全面资源费用评价。在水泥生产的省的层次的扩大 exergy 消费和它的紧张份量上被计算然后在地区性的水平的 exergy 使用的凝块水平也被评估。把分析基于这,他们在在省的水平的 exergy 使用的尺寸和效率的空间差别被识别。而且,他们的地区性的特征被揭示。一些重要结果能如下被拉。首先,不可见的社会费用在生产工业的水泥说明了全部的 exergy 使用的 1/10,当精力元素关于 9/10 分享了时。第二,在生产工业的瓷器水泥的 exergy 使用的粗野分发主要在象安徽和山东省一样的东方区域,并且在象四川省一样的西方的区域被集中。以 exergy 使用,而资本,劳动和外部环境因素的费用在中央、西方的区域为水泥生产加亮不可见的社会费用到某程度,煤和电在东方区域的精力费用中是最高的。第三,在生产工业的瓷器水泥的 exergy 使用的效率分发从西方说明了一个增长特征到东方特别为精力,劳动和大写的效率。环境效率上的评估显示象西藏, Xinjiang,内部蒙古和山西一样的省或区域承担了高得多的环境费用。第四, 23 个省能被欧几里德几何学的距离模型分类进八个组用粗野并且 exergy 使用的效率结果。第五,高工业集中度是为在中国生产工业的水泥的 exergy 效率改进的主要开车因素。 | CHEN Fengnan SHEN Lei LIU Litao GAO Tianming | 2015 | Journal of Geographical Sciences2015，25，11： | 1 |
| 3 | Lactoferrin-Conjugated Polylactic Acid Nanobubbles Encapsulated Perfluoropentane as a Contrast Agent for Ultrasound/Magnetic Resonance Dual-Modality Imaging显示文摘The development of contrast agents that can be activated by multiple modes is of great significance for tumor diagnosis.In this study,the lactoferrin(Lf)-conjugated polylactic acid(PLLA)nanobubbles(Lf-PLLA NBs)were used to encapsulate liquid perfluoropentane(PFP)with the double emulsion method,creating PFP loaded(PFP/Lf-PLLA)NBs for the ultrasound/magnetic resonance dual-modality imaging of subcutaneous tumor.The parti-cle diameter and stability of nanobubbles were investigated by photon correlation spectroscopy.The biocompat-ibility of nanobubbles was preliminarily evaluated by cell proliferation and migration assay,hemolysis rate,and blood biochemistry analysis.A B-mode clinical ultrasound real-time imaging system was used to perform ultra-sonic imaging in vivo.Magnetic resonance imaging in vivo was applied with a clinical 3.0 T magnetic resonance imaging(MRI)scanner system.The mean particle diameter of PFP/Lf-PLLA NBs was 320.2±4.1 nm with a low polydispersity index(PDI,0.145±0.025),and the NBs were negatively charged(−11.4±0.4 mV).The transmis-sion electron microscopy(TEM)results showed that PFP/Lf-PLLA NBs exhibited highly monodispersed and pos-sessed an obvious spherical structure of nanocapsules.Nanobubbles had good stability at 4°C.Different concentrations of the PFP/Lf-PLLA NBs solution had no effect on the cell in cytotoxicity and cell migration,and the results of hemolysis rate and blood biochemistry assay also indicated the good biocompatibility of NBs.On the ultrasound/magnetic resonance imaging of tumor-bearing mice,PFP/Lf-PLLA NBs showed signifi-cantly enhanced contrast ability of tumor tissue.Therefore,PFP/Lf-PLLA NBs had great potential to be a contrast agent for tumor dual-modality imaging in vivo. | Liqiong Ding Pingsheng Li Liu He Fengnan Xu Jieqiong Ding Binhua Luo | 2022 | Journal of Renewable Materials2022，10，3： | 0 |
