This annealing process is performed within an environmental scanning electron microscope (ESEM) by a nanorobot-assisted nanomanipulation system. The results show that the conductivity of the soldered nanostructure is enhanced by about 1000 times after a 130s annealing process. The joining strength on the junction point was also estimated up to 112 MPa (0.22 µN), which is sufficient for the interconnection of the nanomaterials.

In this paper, two kinds of carbon nanomaterials with vertical structures, namely carbon nanowalls and vertically aligned carbon nanofibers, have been prepared and tested to evaluate their heat dissipation performance. Experimental measurements have been carried out to obtain the hotspot temperatures of a test chip with and without the carbon nanomaterials applied. Comparisons of temperature values of the chip at various power loadings show that the utilization of both the carbon nanowalls and the carbon nanofibers can effectively decrease the hotspot temperature.

The model considers the QCM-D disk as a harmonic oscillator and the friction between the disk and the cell is modeled as molecular bond rupturing and the fluidic slip at the interface. The bond formation and rupture events are governed by relative motion between the sensor disk and the cell membrane. We consider this interaction as the main energy dissipation channel for the oscillator, as the dynamic molecular bond rupture and the viscous damping of the trapped liquid at the cell/disk interfacial layer contribute to the most energy loss during the harmonic oscillation. The energy loss due to the frictional slip of the stress fiber/cytoplasm is insignificant compared with the bond rupture. At high bond number conditions, the energy dissipation will be dominated by the bond rupture events at the focal adhesion, and bond number and the size of focal adhesion are linearly related to the energy dissipation factors. These findings can serve as an analytical tool for QCM-D based cell adhesion assays.","PeriodicalId":365399,"journal":{"name":"2019 IEEE 19th International Conference on Nanotechnology (IEEE-NANO)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132668316","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 noted that even though the AFM possesses nanometer imaging resolution, it is hard to achieve nanometer tip locating precision due to complicated uncertainties, especially the nonlinearity of tip-environment interaction and the random drift influence. Since an AFM image is typically utilized as a map for nanomanipulation, the uncertainty distorted image will definitely introduce location deviation between the real and the captured nano-world, which typically leads to low efficiency or even failure of tasks. Besides, complicated tip-environment interaction is generally hard to model and to make accurate prediction, which will also lead to task failure. Therefore, to achieve highly accurate operation at the nanoscale, environmental sensing capability of AFM-based nanorobot should be promoted. In this paper, we propose a local environment sensing approach to detect positioning uncertainty between nanorobot tip and its surroundings by developing a multi-functional spiral local scan (MSLS) strategy comprised of structured objects location detection function and local surroundings imaging function. Briefly, sphere/cylinder-like object location detection strategies were proposed; a tip motion predictor was developed to tackle the heavy noise issue of detection tasks at dozens of nanometers scale, based on which a local area imaging approach was established. Efficiency of the MSLS method was verified through experimental study.","PeriodicalId":365399,"journal":{"name":"2019 IEEE 19th International Conference on Nanotechnology (IEEE-NANO)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130969597","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}
