In the design of an adsorption based CO2 adsorption device, the choice of the adsorbent is the most crucial design consideration. In this paper, several CO2 selective adsorbents will be trialed and the adsorbent hollow fibers will be prepared and tested in order to optimize robustness/integrity and selectivity. These adsorbent hollow fibers are light, could be as small as 0.5 mm to 3 mm in diameter. It is ideal as fiber cartridges for CO2 removal from enclosed spaces, because of their small dimension, and the open finger-like structure giving ready diffusion of small CO2 molecules and the high surface-to-volume ratio that can be achieved (>3000 m2/m3). The open finger-like structure in the adsorbent hollow fibers provides more accessibility for the adsorbate molecules to reach the adsorption sites and hence gives better kinetic performance. The results show that an adsorbent hollow fiber module has a far sharper breakthrough curves and longer times to breakthrough for CO2, than for equivalent beds of pellets, and the 13X hollow fibers have a superior performance for the adsorption of CO2 over the other hollow fibers. This means that the adsorbent hollow fibers with the advantages of higher surface-to-volume ratio, low pressure drop and low mass transfer resistance give great potential on CO2 adsorption and further environmental applications.","PeriodicalId":112068,"journal":{"name":"2013 IEEE 8th Nanotechnology Materials and Devices Conference (NMDC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121111886","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}

All of the sensing layers were prepared by sputtering, except, the amorphous carbon film was deposited by a DB-HWCVD system. We used Raman, XRD, SEM and AFM, for bond structure measurement, analyzing crystalline, examination of surface roughness and morphology inspection, respectively. Based on the SEM images, we can see that at the etching temperature of 90°C and etching time of 60 minutes can get the best quality nanorods structure. To measure the voltage sensitivity of the device, current-voltage (I-V) curves were displayed on a curve tracer (HP 4145B). Experimental results show that, in 2D thin film structure, under 3000 ppm, the WO3 sensor has the highest sensitivity of 199% (100°C) and 496% (400°C), respectively. Compared to the reported O2 sensors, we achieved the higher sensitivity, lower operation temperature and wider sensing range.","PeriodicalId":112068,"journal":{"name":"2013 IEEE 8th Nanotechnology Materials and Devices Conference (NMDC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127044445","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 L0.06Z0.94O piezofilms are grown by radio frequency magnetron sputtering system and post-treated with ultraviolet (UV)-ozone illumination. The structural and chemical evolutions through various illumination times of the predominantly c-axis orientation LZO films are investigated. The largest piezoelectric coefficient (14.87 pC/N) of the LZO film is obtained after 120 min UV-ozone illumination, which can be ascribed to better crystallization and fewer oxygen-related defects. Furthermore, we adopt the wet chemical etching method and the lift-off process to pattern the piezofilms and electrodes of the BAR device, respectively. The fabricated resonator exhibits high quality factor (Q = 1112) at ~500 MHz. The experimental results verify the crystallinity and the uniformity of the piezofilms play crucial roles of the BAR devices.","PeriodicalId":112068,"journal":{"name":"2013 IEEE 8th Nanotechnology Materials and Devices Conference (NMDC)","volume":"30 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131775780","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}
