The result showed that half waveplate have electrical to optical conversion efficiency of 15.6 mW/A as compared to quarter waveplate is only 8.74 mW/A. The threshold current for SHG is found 5.3 A with half waveplate and 5.9 A with quarter waveplate. The high performance shown by half waveplate is realized due to the good mode matching after converting the polarization state.","PeriodicalId":6354,"journal":{"name":"2010 International Conference on Enabling Science and Nanotechnology (ESciNano)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78317431","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 thermal interface resistance results in a finite temperature discontinuity at the interface between the two materials. Reducing the thermal interface resistance between silicon chips and the packaging material is very critical for efficiently extracting heat and ensuring reliable operation of ICs. The large thermal conductivity of carbon nanotubes makes them very ideal for developing thermal switches and thermal interface materials [2]. We have investigated the thermal interface resistance between carbon nanotubes and silicon using molecular dynamic (MD) simulations.","PeriodicalId":6354,"journal":{"name":"2010 International Conference on Enabling Science and Nanotechnology (ESciNano)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75966733","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 use of each new material has led to the improvement in luminous efficacy by an order of magnitude. The incandescent light bulb, invented by Edison in 1879, will be phased out over the next few years as governments sought to ban its manufacture and use because of its low efficiency (< 5%) and to introduce green technology. The fluorescent lamp, which is widely used to replace the incandescent bulb with its use of mercury and presence of lead in some phosphors, is seen as an interim measure.","PeriodicalId":6354,"journal":{"name":"2010 International Conference on Enabling Science and Nanotechnology (ESciNano)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75748019","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}

It is revealed that the particles shape of PSN changed from spheric to eight-shaped after solar radiation. Reduction of the size as much as 29.5% after 5 minutes exposure was also observed in PSN particles. Changes in the molecular structure of the PSN particles after solar radiation were observed where some of the phenyl moieties of polystyrene broke down to facilitate carbon-carbon cross linkage bonds. These results demonstrated that the shrinkage of PSN particles is caused by the change of the molecular structure of polystyrene.","PeriodicalId":6354,"journal":{"name":"2010 International Conference on Enabling Science and Nanotechnology (ESciNano)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75268335","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}

Recently, self-healing phenomena have attracted particular attention for developing sustainable structural materials [3], where extensive studies have been reported on polymeric materials capable of autonomous repairing macroscopic fractures or restoration lost mechanical strengths [4, 5]. On the other hand, for exploiting molecular devices that can self-repair elaborate functions, one may encounter different problems originating from much smaller size regimes. However, no rational strategies have yet been proposed for addressing this challenging issue. In our previous paper, when a phosphorescent columnar assembly of trinuclear gold(I) pyrazolate complex [Au3Pz3] is confined in the nanoscopic channel of hexagonal mesoporous silica [Au3Pz3]/silicahex (Fig. 1), upon stepwise heating from 20 °C to 140 °C in 45 min, the one-dimensional molecular assemblies are not only protected from thermal disruption but also strongly encouraged to self-recover to 100% in 5 h from a heat-induced structural damaged [6].","PeriodicalId":6354,"journal":{"name":"2010 International Conference on Enabling Science and Nanotechnology (ESciNano)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74068874","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}

ZnO NWs have been synthesized via different routes by many research groups [2–4]. In order for these building blocks to be incorporated into functional nano-devices, controlled synthesis of the ZnO NWs to obtain features such as the desired size, shape and alignment should be fulfilled. This is a rather challenging task. A better understanding of the growth mechanism of ZnO NWs may be helpful to resolve these uncertainties. However, the underlying mechanism for the growth of the ZnO NWs for both self-catalyzed and Au-catalyzed ZnO NWs, have not been well elucidated.
