The strategy can be used to fabricate bilayer and trilayer sulfite biosensors, consisting of nanolayers of polypyrrole-sulfite oxidase, polypyrrole-dextran-sulfite oxidase, polypyrrole-chloride and/or polypyrrole-nitrate films. It has been demonstrated that the nature of the outer nanolayer has a significant influence on the selectivity and sensitivity of the amperometric nanocomposite biosensor. The presence of interferants, such as oxalic and tartaric acids at levels usually present in wine and beer did not interfere with the nanocomposite biosensor. The successful application of the nanolayer biosensor to sulfite determination in some wine and beer samples without sample pre-treatment is demonstrated.","PeriodicalId":6429,"journal":{"name":"2007 Cleantech Conference and Trade Show Cleantech 2007","volume":"118 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2006-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77424862","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}

The silicon chip contains an array of nano-volume electrochemical cells that house the bacteria, connected to a sensing and data analysis unit. Each of the electrochemical cells in the array can be monitored independently and simultaneously with the others. A measurable current signal, well above the noise level, was produced within less than 10 minutes of exposure to representative toxicants.

Such a concept based on structures fabricated using stacked semiconducting layers to obtain a multi spectral photoresponse is investigated in this paper. Based on the selected approach, fabrication of a dualband UV/IR photodetector with a reasonable responsivity at room temperature has been demonstrated. The integrated device is capable of detecting optical emissions separately in the UV and IR parts of the spectrum. The responsivities of this device are ~0.01A/W, at a peak wavelength of 300 nm and ~0.08 A/W, at a peak wavelength of 1000 nm, respectively. The described dual-band photodetectors can be employed for false alarm-free fire/flame detection and advanced hazardous object or target detection and recognition in several industrial, military, and space applications.","PeriodicalId":6429,"journal":{"name":"2007 Cleantech Conference and Trade Show Cleantech 2007","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2006-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88012934","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}

These fluids improve gas-liquid oxygen mass transfer up to 6 fold in an agitated, sparged, cell-free reactor and show remarkable stability in high-ionic strength media over a wide pH range. A combination of experiments using physical and chemical methods has been used to show that the mass transfer coefficient kL and the volumetric mass transfer coefficient kLa are enhanced in the presence of nanoparticles. An increase of 40% in the oxygen uptake rate has been achieved in Escherichia Coli fermentation at a 5.5-L scale by using 0.6% w/w particles dispersed in fermentation media. The enhancement in mass transfer is directly translatable into increased fermenter productivity.","PeriodicalId":6429,"journal":{"name":"2007 Cleantech Conference and Trade Show Cleantech 2007","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2006-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78442258","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}

To truly qualify as “green” technology, applications of nanotechnology will need to demonstrate that such exposures and potential concerns for health and environmental risk can be managed adequately.

It is unclear, however, whether the benefits of MEMS application far outweigh the associated cost. A quantitative approach for benefit and cost calculation of MEMS application for structural health monitoring of transportation infrastructure will be a major step forward to provide guidance to potential MEMS users. In this paper, we develop a fuzzy logic-based approach (since MEMS benefits are generally fuzzy in nature and at best, they can be quantified using fuzzy-logic) for benefit-cost calculation associated with MEMS application. Real-world case studies will be presented in future works using the proposed fuzzylogic approach.","PeriodicalId":6429,"journal":{"name":"2007 Cleantech Conference and Trade Show Cleantech 2007","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2006-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81778788","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}
