However Lack of controllability is still an obstacle for utilizing it in the fabrication of 3D tissue constructs and accurate targeting in mass delivery. Here, we proposed a new method for achieving magnetic alginate hydrogel microfiber by encapsulating magnetic nanoparticles inside alginate solution and solidifying the magnetic alginate into hydrogel fiber inside microfluidic chips and micro syringe system. The fabrication method for 3 layered microfluidic channel was given. In the experiments, the magnetic nanoparticles and alginate solution present to be a uniform suspension, no aggregation of magnetic nanoparticles was found, which is crucial for flow control inside microfluidic chips. By regulating the flow rate of different solutions inside the chip, magnetic hydrogel fiber and pure hydrogel fiber are achieved with controllable diameters. Patterning device and magnetic pillar were employed as a magnetic guidance to pattern and align the magnetic fibers. The proposed method for fabricating magnetic hydrogel fiber holds great potentials to engineer 3D tissue constructs with complex architectures and hierarchical vascular networks to mimic the native tissue microenvironment.","PeriodicalId":189707,"journal":{"name":"2013 13th IEEE International Conference on Nanotechnology (IEEE-NANO 2013)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121498650","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 nanorods having average diameter of 250-300 nm and average length of 400-500 nm is then surface sensitized by Palladium (Pd) nanoparticles. After structural and electrical characterization, both unmodified and surface modified nanorod based sensors were tested for Hydrogen (H2) detection in the resistive mode with Pd-Ag catalytic electrode. Both types of sensors offered appreciably high dynamic range (100ppm-20000ppm) at their respective operating temperature of 200°C and 150°C with corresponding response magnitude of ~76% and ~88%. Apart from improvement in response magnitude and reduction in the optimum operating temperature, the surface modification of nanorod also offered significant improvement (faster) in response time and recovery time. The high dynamic range of sensing (H2) makes this sensor useful for wide range of applications starting from domestic to commercial appliances.","PeriodicalId":189707,"journal":{"name":"2013 13th IEEE International Conference on Nanotechnology (IEEE-NANO 2013)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131543694","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 electrochromic behaviors of the PMeT/ITO/Glass were performed in 0.1 M lithium perchlorate (LiClO4)/propylene carbonate (PC) electrolyte.

Thermal interface materials play a key role in the development of solutions for thermal management in microelectronics. In this paper, mechanical properties of a nanotechnology enhanced thermal interface material (Nano-TIM) were studied. The material is based on Sn-Ag-Cu based alloy reinforced with nano scale fiber matrix. Tensile tests were used to investigate and compare the elastic modulus at room temperature and mechanical strength between 20 to 100°C. Scanning Electron Microscopy (SEM) analysis techniques were used to investigate the morphology of the fracture section after tensile tests as well as the internal structure of the samples. The results show that the Nano-TIM can have a significantly lower elastic modulus compared to the pure alloy phase of SnAgCu due to its fiber phase. A lower elastic modulus of the solder joint can be important since it will reduce the stress transfer across the interface. This is particular important when the joint substrates have mismatching coefficients of thermal expansion. The findings of this study thus indicate that the Nano-TIM may provide a useful alternative to improve the thermomechanical reliability compared to pure solder joints.","PeriodicalId":189707,"journal":{"name":"2013 13th IEEE International Conference on Nanotechnology (IEEE-NANO 2013)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130332034","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 simple nature of our process leads to formation of Ag continuous and seamless integrated NWs-graphene hybrids with excellent interfacial electron transfer, avoiding the interface problems associated with the multiple-step process Interestingly, the one-step process also leads to the synergistic cooperation of graphene and Ag NWs: graphene promotes the continuous and preferential growth of long NWs by suppressing the deposition of undesirable Ag nanoparticles and short Ag NWs and facilitates the charge transfer and reactants transport by bridging the random Ag NWs, whereas Ag NWs prevents the aggregation of individual graphene sheet. By harnessing the synergy between individual constituents and their advantages, we show that the hybrid film exhibits enhanced electrochemical activity for the detection of H2O2. We envision that the new nanostructured electrode with enhanced electrocatalytic activity offers great promise for new class of biosensors in environmental and biomedical applications.","PeriodicalId":189707,"journal":{"name":"2013 13th IEEE International Conference on Nanotechnology (IEEE-NANO 2013)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116536692","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}
