This paper presents a comprehensive molecular dynamics simulation study on the mechanical properties of finite graphene with vacancy defects. We characterize the strength and stiffness of graphene using the concept of surface stress in three-dimensional crystals. Temperature and strain rate dependent atomistic model is also presented to evaluate the strength of defective graphene. Free edges have a significant impact on the stiffness; the strength, however, is less affected. The vacancies exceedingly degrade the strength and the stiffness of graphene. These findings provide a remarkable insight into the strength and the stiffness of defective graphene, which is critical in designing experimental and instrumental applications.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114078208","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 overall goal is to define, analyze and evaluate classical and quantum-mechanical information measures pertained to data processing by low-power nanoelectronic devices, nanoICs, nano-waveguides, CMOS nanophotonics, etc. Electronic, optoelectronic and photonic systems operate on the electron- and photon-induced transductions. There are fundamental differences in physics, arithmetics, device- and system-level solutions as electrostatic and quantum phenomena are utilized. This paper analyzes multi-physics quantum↔classical processing. We enable a knowledge base in cognizant areas across computer science and engineering. Our findings enable existing and future communication, sensing, information fusion, computing and processing platforms. Consistent tools and practical schemes facilitate developments of novel engineering solutions, technical readiness, technological capabilities and commercialization capacities.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121101447","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}

Here a low-cost solid-state supercapacitor of high energy density is fabricated with a facile method. The electrodes of the supercapacitor are made of a phytic acid-crosslinked freestanding film of polyaniline and ground carbon fibers and the electrolyte gel is composed of sulfuric acid and polyvinyl alcohol. Our results show that a maximum capacitance of 273.6 F/g (1.6 F/cm2) at a current density of 0.08 A/g can be achieved by the supercapacitor, which is significantly higher than most solid-state ones reported in the literature. The ability to achieve a high-capacitance supercapacitor with good cyclic stability is mainly attributed to excellent infiltration of the electrolyte gel into the electrodes. The developed lightweight, thin, flexible, and environmental friendly supercapacitor would have potential applications in various energy storage devices.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125047241","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 confirm the chosen emitter material's suitability as a photocathode, analyses were performed by X-ray diffraction (XRD) and ultraviolet photoelectron spectroscopy (UPS). Hereby, thin LaB6 films sputtered with higher argon flow rate and sputtering power produced a (100)-oriented film texture yielding work functions in the range of 3.42 to 4.05 eV, accordingly. Photoemission measurements were also realized, whereby quantum efficiency (QE) of thin LaB6 films is still too low compared to laser driven photocathodes when excited by 4.5 eV photons.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121483847","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}

This paper illustrates the relationship between the chemoattractant gradient and the cell velocity quantitatively, using a single-cell motility assay method based on optically manipulated microsources. A case study was performed on leukemia cancer cells. Quantitative study indicates that the cell is sensitive to the gradient, and can move faster under a high gradient. Based on the quantitative relationship, a control strategy was proposed to realize automatically induced cell migration.

Metal-covered GaAs are used to form both arms of an interferometer, while voltage-controlled, localized carrier concentration provides modulation to the signal propagating phase. Relative phase differences between THz beams in separate arms of the interferometer can give rise to deflected radiation in the far field, which is further converted to a digitized output by a spatially arranged detector array. Applying the beam deflector with a full differential implementation of the input voltage signal and a combination of nonlinear detector arrays with carefully designed gain and saturation power, a 3-bit ADC with > 60 GS/s operation speed and direct digitized readout is demonstrated.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115180074","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}
