Hydrophobic drugs can be complexed within the hydrophobic dendrimer interior to make them water‐soluble. The equilibrium partition of hydrophobic solutes into a dendrimer with hydrophobic interior from aqueous solutions is studied by dissipative particle dynamics. The drug is mainly distributed in the vicinity of the interface between hydrophobic interior and hydrophilic exterior within a dendrimer. The partition coefficient, which is defined as the concentration ratio of the drug distributed within dendrimer to aqueous phases, depends on the interaction between drug and hydrophilic dendrimer exterior. Increasing the repulsion between them reduces the solubilization ability associated with the dendrimer.","PeriodicalId":46935,"journal":{"name":"Complex Systems","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2008-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1063/1.2897851","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58348212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A knowledge of ice helps us to comprehend water, a simple molecule, but one with much complex behaviour. Our aim is to understand the morphologies and physics of thin icy films. To treat this complex system we have developed new experimental capabilities with an environmental scanning electron microscope (ESEM) capable of working with ice films, at the same time as new simulation approaches to understanding the physics of ice morphology. A comprehension of the physics of thin‐film morphologies has applicability beyond ice to thin films of metals, ceramics, and other materials.","PeriodicalId":46935,"journal":{"name":"Complex Systems","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2008-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1063/1.2897880","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58348275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bond fluctuation model(BFM) was used to describe amphiphile, where excluded volume effect and flexible movement of polymer bonds are ascertained. The ratio of water to oil was changed from 10/85 to 50/45 with 5% fixed dilute amphiphiles. For small water/oil ratio, many cubic water clusters surrounded by loop‐shaped amphiphiles dispersed in oil and they were bridged between each other by bridge‐shaped amphiphiles. On the other hand, phase separation between water and oil plus amphiphiles clearly occurred for large water/oil ratio, where water formed one grid‐shaped cluster. At some intermediate water/oil ratio, water cells aggregated into two water clusters with shape of rectangular rod, spread in x‐ and y‐directions and separated in z‐direction by mainly loop‐shaped amphiphiles, where water clusters and ...","PeriodicalId":46935,"journal":{"name":"Complex Systems","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2008-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1063/1.2897844","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58348172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
