Sub-wavelength metal nanostructure fabrication by parallel dip-pen nanolithography
Metal nanostructures in sub-wavelength scale have attracted interests in materials engineering and optics research. Metal nanostructures in sub-wavelength scale have been used as plasmonic diffraction gratings and negative index metamaterials. E-beam lithography has been commonly [...]
Laser Writing of Metallic Nanostructures in a Polymer Matrix with Applications to Metamaterials
We present a novel laser-based method for directly writing metallic nanostructures in a polymer matrix with sub-wavelength resolution [1]. The method involves two-photon lithography (TPL) in which a femtosecond-pulsed laser induces two-photon initiated in situ [...]
Brittle Ductile Transition in Carbon Nanotube Bundles
Cornwell C.F., Allen J.B., Marsh C., Carlson T., Stynoski P., Newcomb B., Masters B., Ebeling R., Welch C.R., U.S. Army Engineer Research and Development Center, US
Carbon nanotubes (CNTs) attract considerable interest because of their extremely high stiffness, strength, and electrical and thermal conductivity. While the strength and stiffness of CNTs can be extremely high, bundles composed of aligned CNTs are [...]

Magnetic nanoparticles as components of magnetoresistance sensors: the gGMR-sensor
Superparamagnetic microbeads and nanoparticles have a wide range of applications. Due to their magnetic stray field they influence soft magnetic material nearby which allows for the magnetic recognition of such particles by magnetoresistive sensors. Such [...]
Multiferroic StTiO3/BiFeO3 Superlattice:Theory and Experiment
Materials designing using the concept of artificial layered structures has opened up a new vista in process engineering owing to the possibility of evolving unusual and novel functional properties which are often not found in [...]
Layered nanocomposites of plate-like particles and polymers
Clay-polymer nanocomposites have emerged as a new class of material in recent years because a low addition of clay (<5 wt.%) in a polymer matrix causes significant improvement in material properties. They represent the low [...]
Fabrication of the α–Fe2O3 nanowires and application of the photodetector/optical switching
In this study, we demonstrate a rapid and easy method to synthesis α-Fe2O3 nanowires (NWs). The density of the α-Fe2O3 NWs were successfully control by different thickness of Fe thin film within 10 hours by [...]
Fabrication of Structurally Tailored Cobalt Nanowires
we report an interesting observation of effecting structural transition of electrochemically deposited cobalt nanowires with change in aspect ratio of the nanowires. This change can be controlled by the deposition temperature. These nanowires were deposited [...]
Integrated phase-Change memory in Bi2Te3 nanowires
Han N.A., Kim S.I., Yang J.D., Lee K., Sohn H., So H-M, Sohn H., Ahn C.W., Yoo K.H., Yonsei University, KR
Bismuth telluride (Bi2Te3) and its alloys are considered to be the best avaiable materials for near room-temperature thermoelectric applications. Moreover, because low-dimensional thermoelectric materials are expected to have a higher figure of merit due to [...]
Fluoropolymer Nanofibers (VDF-TFE 5 mol%) by Electrospinning
Poly(vinylidene fluoride) with 5 mol % of tetrafluoroethylene copolymer (VDF-TFE), is known to have the same crystal structure as pure PVDF as well as similar unique electrical properties. The β-phase of this polymers has strong [...]
Self-assembly of Nanostructured ZnO-based Homojunction by Two-step Method
Changand Y.Q., Lu Y.D., Guo J.L., Cui X.D., Yang L., Wang Y.W., Long Y., University of Science and Technology of Beijing, CN
In this work, self-assembly of radial nanostructured ZnO homojunction were synthesized by a kind of two-step method. A supplementary growth mechanism is used to explain the formation of nanostructured ZnO homojunction. Photoluminescence (PL) spectra reveals [...]
Critical exponents from parallel plate geometries with periodic and antiperiodic boundary conditions
We present a one-particle irreducible formalism to compute critical exponents for a parallel plate geometries for periodic and antiperiodic boundary conditions, at least at two loop order in perturbation theory.
