Organic-soluble Ag nanocrystals(NCs) with tunable sizes in the range from 5.4 to 22.1 nm were synthesized by a facile, reproducible and easily scaled up route using water as solvent in the presence of oleic acid and an *** synthetic Ag NCs exhibits excellent hydrophobicity and can be well re-dispersed in various non- or weak-polar *** tunable sizes of the Ag NCs were achieved by simply adjusting the initial precursor ***-scale synthesis of the Ag NCs was realized at a high AgNO3concentration(0.4 mol/L).As much as 16.2 g highly uniform organic-soluble Ag NCs with 5 nm average diameter can be readily synthesized at low cost in a single reaction only using 400 mL water as solvent,which is adaptable to the industrial scale *** structure of the obtained Ag NCs was investigated in detail by X-ray diffractometry,transmission electron microscopy,Fourier transform infrared and thermal gravimetric analysis *** results reveal that the surface of the organic-soluble Ag NCs is coated with the monolayer surfactants consisting of oleic acid and the *** addition,on the basis of the sufficient evidences,a proposed mechanism based on the "bilayer surfactant-controlled reaction" successfully demonstrates the formation of high quality organic-soluble Ag NCs in the aqueous solution.

高效抗反转录病毒治疗(HAART)通过有效抑制体内艾滋病病毒(HIV)的复制,极大地降低了艾滋病(AIDS)的发病率及病死率,使HIV感染从一种致死性疾病转变为需要终身服药的可控性慢性病,因此服药依从性成为影响疗效的关键因素。西方国家关于抗... 详细信息

高效抗反转录病毒治疗(HAART)通过有效抑制体内艾滋病病毒(HIV)的复制,极大地降低了艾滋病(AIDS)的发病率及病死率,使HIV感染从一种致死性疾病转变为需要终身服药的可控性慢性病,因此服药依从性成为影响疗效的关键因素。西方国家关于抗反转录病毒治疗的依从性研究有多种理论基础模型,而国内关于服药依从性的基础理论研究尚有待进一步深入。此文主要就信息-动机-行为技能模型(IMB)在HIV感染者服药依从性方面的应用进行阐述。
