The data are analyzed using both the precise point positioning (ppp) and network methods: in the former, the time differences between the satellite clocks and system time are fixed to predetermined values. In the latter, the time differences of both the satellite clocks and the receiver clocks are estimated relative to some reference clock (usually a ground-based receiver clock). We also analyze data both with and without the added constraint of double-difference ambiguity fixing. We find that between-site frequency comparisons are largely unaffected by site-based and satellite-based systematic errors when 100% of the double-difference ambiguities are fixed. We also find that in the ppp method, although fixing ambiguities removes between-site frequency errors, it can cause errors in the values of the individual receiver clocks relative to system time. Finally, we find that when a network solution is performed and ambiguities are not fixed, an error made at site A may adversely affect frequency comparisons between sites B and C","PeriodicalId":445945,"journal":{"name":"2006 IEEE International Frequency Control Symposium and Exposition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130492324","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 zinc oxide (ZnO) nanotip-based quartz crystal microbalance (QCM) sensor is developed as a solution for accurate and inexpensive biosensors. The QCM sensor composed of single crystalline ZnO nanotips grown on top of a gold electrode using metal-organic chemical vapor deposition (MOCVD). Scanning electron microscopy (SEM) shows that the ZnO nanotips are uniformly aligned with their c-axis normal to the gold surface, giving a large surface area for sample up-taking. The ZnO nanotip coated QCM sensor shows a 10-time larger frequency shift than that of regular QCM sensors, when measuring the same DNA oligonucleotide (5'-AGAAAATCTTAGTGTC-3') solution. In addition, the hydrophilic behaviors of the nanotip array significantly reduce the required liquid volume for effective detection. 0.5 mul solution fully covers the QCM sensor area (0.2047 cm2), while a minimum of 16 mul liquid is required to cover a flat surface of the conventional QCM. ZnO nanotips show superhydrophilicity with a contact angle of ~0deg under ultraviolet (UV) illumination. The superhydrophilic sensor surface significantly boosts the solution taking up ability; therefore, enhances the sensitivity of the QCM sensor. The effects of ZnO nanostructure on the bulk acoustic wave (BAW) are also discussed","PeriodicalId":445945,"journal":{"name":"2006 IEEE International Frequency Control Symposium and Exposition","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123160941","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}
