This makes organics ideal for many applications in spintronics since the longevity of spin polarization is an important criterion for virtually all spintronic devices.

Finally, we present results pertaining to the transverse spin relaxation time (T2 time) in organics since it is critical for quantum computing applications.","PeriodicalId":6415,"journal":{"name":"2007 7th IEEE Conference on Nanotechnology (IEEE NANO)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78778518","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}

A key element that serves as the foundation for the translational applicability of this material is represented by the examination of its effects upon cyto-regulatory gene programs that govern processes such as cellular stress and inflammation. With a better understanding of the cellular response to these materials, improved design principles can be examined towards the utilization of these polymers for biomedical applications in vivo. Here we present a comprehensive assessment of the basal levels of secretion for a spectrum of inflammatory cytokines/molecules including tumor necrosis factor-alpha (TNFalpha), interleukin-6 (IL-6), interleukin-12 (IL-12), as well as inducible nitric oxide synthase (iNOS). In addition, we examine the effects of cellular incubation with the triblock copolymer in solution upon morphology as well as growth capabilities in vitro. The foundational information gleaned from this study will provide an important glimpse into the internal cellular response to foreign material contact towards the forging of devices fabricated at the interface of biology and artificial materials.","PeriodicalId":6415,"journal":{"name":"2007 7th IEEE Conference on Nanotechnology (IEEE NANO)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83504701","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 novel combined sliding mode approach has been investigated in this paper to obtain robust nonlinear control scheme for nano-manipulation. First (classical) and second order (SOSM) sliding mode techniques have been developed and applied to nonlinear dynamical and uncertain model of AFM cantilever beam to track the desired trajectories. The simulation results show chattering in reaching phase of classical sliding mode and undesired trajectory twisting in sliding phase of SOSM. Hence, combined first and second order sliding mode is proposed to achieve robust chattering-free vibration control of AFM tip.","PeriodicalId":6415,"journal":{"name":"2007 7th IEEE Conference on Nanotechnology (IEEE NANO)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88371175","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}

Such strides have led to studies and experimental tests using these devices in non-volatile memory arrays. However, the architecture of such arrays makes it difficult to accurately determine the value of each stored bit in the memory. When reading, each bit is effected by the rest of the memory through variable numbers of `stray current pathsiquest. This paper presents the idea of data encoding to thwart the impacts of these stray currents. The results show that this encoding method makes each bit unique and deterministic, independent of the memory array size.
