Using calibrated 3D TCAD simulations, the efficacy of the proposed device as a biosensor is shown. The dopant implantation-free approach results in simplified fabrication process with reduced thermal budget and hence, increased suitability to 3D integration and fabrication on glass or plastic substrates. The device is also expected to give tolerance against dopant fluctuations induced variability in the detection sensitivity.","PeriodicalId":292399,"journal":{"name":"2017 IEEE 17th International Conference on Nanotechnology (IEEE-NANO)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116065549","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}

In this paper, we extend the flow-based crossbar computing approach to approximate stochastic computing. First, we show that the natural flow of current through probabilistically-switching memristive nano-switches in crossbars can be used to perform approximate stochastic computing. Second, we demonstrate that optimizing the approximate stochastic computations in terms of the number of required random bits leads to stochastic computing using bit-vector stochastic streams of varying bit-widths — a hybrid of the traditional full-width bit-vector computing approach and the traditional bit-stream stochastic computing methodology. This hybrid approach based on bit-vector stochastic streams of different bit-widths can be efficiently implemented using an in-memory nanoscale memristive crossbar computing framework.","PeriodicalId":292399,"journal":{"name":"2017 IEEE 17th International Conference on Nanotechnology (IEEE-NANO)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122101138","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}

Space charge measurements showed huge charge injection and accumulation in the base LDPE material. In particular, at room temperature a positive charge packet was observed moving rapidly from the anode to the cathode, enhancing space charge accumulation in the insulation bulk. On the contrary, space charge buildup was significantly reduced in nanocomposites with a filler content smaller than 0.1 wt%. Increasing temperature, the base material accumulate much less charge therefore the effect of the nanofiller becomes less evident than at room temperature.","PeriodicalId":292399,"journal":{"name":"2017 IEEE 17th International Conference on Nanotechnology (IEEE-NANO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128211989","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}

Cellular self-organization is highly related to the property of ECM. Here, we investigate the 3D hollow spheroid formation process of vascular mesenchymal cells (VMCs) at the interfaces between hydrogel ECMs with different mechanical properties. The combined hydrogel geometrically consisted of two subparts differing in their stiffness and had geometric interfaces between those two subparts. The experimental results show that 3D hollow spheroids with large cavity generated around interfacial regions of hydrogels, which were not observed in a common 3D culture with sole-stiffness hydrogel. The hollow spheroids emerged because of the tailored groove dimensions of hydrogel interface and the concentration gradients of proteins and cells across the hydrogel interfaces. This experimental demonstration provides a potential method to improve the biological properties of multicellular spheroids for fundamental and therapeutic applications.","PeriodicalId":292399,"journal":{"name":"2017 IEEE 17th International Conference on Nanotechnology (IEEE-NANO)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128234885","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 herein reported Monte Carlo simulation includes charge diffusion and trapping, charge recombination, charge transport and adsorbents mineralization. Specifically, the cement microstructure influence on the photocatalysis is studied. It was found that inherent cement porosity promotes adsorption of inorganic species, charge carriers trapping in the surface and photon absorption, which results in enhanced TiO2 photocatalysis.","PeriodicalId":292399,"journal":{"name":"2017 IEEE 17th International Conference on Nanotechnology (IEEE-NANO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129478601","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}
