In this work, we have synthesized Ag-Graphene Nanocompostie (AGN) by a simple method under mild condition. Further, Composites of poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) participated by AGN have been studied. The interaction and photoluminescence quenching of MEH-PPV/AGN composites have been observed using UV-visible and fluorescence spectroscopy. Based on UV-visible spectrum of different concentration of AGN blending with MEH-PPV, the absorption range was markedly enlarged, indicating the formation of ground-state charge-transfer complex (CTC). Besides, photoluminescence (PL) spectra of the MEH-PPV/AGN nanocomposite show an efficient PL quenching effect. Both of these results indicate that AGN could apply in photovoltaic device as an acceptor material.

In this paper, the development of a nanorobotic station for acquisition of cellular electrical and mechanical information is reported. This station involves the development of a nanomanipulation platform and a planar patch-clamp module. The nanomanipulation platform not only enables the observation of biological cells, but also has the ability to give a precise pico-Newton force stimulus on a certain position of cells. The membrane potential of cells can be recorded by the patch clamp module. The module also has the ability to generate electric stimulus to the biological cells. This station provides a method to research both mechanical and electrical properties of living cells.

Material reliability is among the crucial factors that impact material performances before device applications. In order to predict material reliability, accelerated aging study-a study to predict material shelf life when subjected to temperature, was performed on Silicon Nanowires. We investigated the effects of process conditions on the diameters and the quality of Si NWs using Atomic Force Microscopy. The experimental results revealed diameter of Si NWs has linear relationship with varying temperature. These results are of significant importance and will be a critical design consideration for the manufacture of Nanoelectromechanical systems involving Si NWs.

Physiological conditions of biological samples are regulated by many different parameters including mechanical and biochemical factors etc. Single-cell studies of these parameters are challenging by using conventional bioanalysis methods. However, with the recent advancement in nanotechnology, single-molecule and single-cell analysis is much more accessible. Understanding the changes of neuroblastoma cells in different mechanisms is critical for fundamental research in neurosciences. Here, we investigate the mechanical behavior of SH-SY5Y cells using atomic force microscopy. Topographic imaging of the cells and real-time quantitative analysis of their mechanical properties will be presented in the paper.

Drag reduction of liquid flows on solid/liquid interface has become an important issue with the development of microfluidics systems. Theoretical and experimental studies have shown that at the solid-liquid interface the presence of nanobubbles is believed to be responsible for boundary slip, and the size, quantity and distribution of nanobubbles on hydrophobic surface will influence the slip length. In this paper, surface nanobubbles formed on Polystyrene (PS) films were imaged by atomic force microscope (AFM), and the influences of PS solution concentration adopted when spin-coating on nanobubbles were investigated.

Microfluidic platforms provide elegant schemes for isolation of rare cells from the blood. Hierarchical 3-dimensional architectures with silicon nanopillar forests draw advantage of unique surface interactions with target cells to aid capture and adhesion. Microchannels with numerically optimized designs of micro post arrays maximize contact frequency with the cells in flow. We describe a scheme to fabricate ordered nanopillar forests on the sidewalls of these micro posts and functionalize them with SELEX nucleic acid aptamers. Our microfluidic platform, designed for 90% contact probability, facilitates technologies for highly selective and specific capture of circulating tumor cells.

We propose a method to solve differential problems, and in particular quantum wave equations, with periodic boundary conditions, in the direct space using periodic repetitions of the cardinal sine functions as basis functions, and we adopt it for the solution of the Schrödinger equation and, in graphene nanoribbons, of the Dirac equation. We show that this method, unlike finite-difference approaches, allows to avoid the errors deriving from the numerical approximation of the derivatives, and, if all of the terms of the equations are properly handled, is equivalent to a reciprocal space solution.

In order to understand surface plasmon resonance of anisotropic metal nanocrystals, we have produced Ag nanorods with well-controlled aspect ratio by soft template method with seed-mediated. The aspect ratio of synthesized Ag nanorods can be tuned flexibly by changing the amounts of seeds. This provides a convenience for studying localized surface plasmon resonance (LSPR) properties of Ag nanorods. Based on these excellent properties, we calculated the extinction spectrum and electrical field distribution of Ag nanorods near the AgNCs by discrete dipole approximation (DDA) method and investigated the effect of incident and polarization direction on far-field and near-field characteristics. These results could be helpful for us to take the advantage of excellent optical properties on optoelectronic and biomedical field.

This protocol is based on Einstein-Podolsky-Rosen (EPR) pairs. If any eavesdropper tries to steal dealer's messages, the lawful participants will perceive it and abort their transmission.

Large-area CuO nanowires have been synthesized by thermal oxidation of porous copper film in static air. The effect of the thermal oxidation temperature and duration are found to influence the growth of CuO nanowires significantly. With an optimized condition, the porous copper film is converted into pure CuO. The application of the as-synthesized CuO nanowires in nanoenergetic materials is also studied. The ignition temperature of the reaction between Al and CuO is significantly lower than those in micro scale or bulk composites.
