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 [...]

Laser Writing of Metallic Nanostructures in a Polymer Matrix with Applications to Metamaterials

Shukla S., Vidal X., Furlani E.P., Swihart M.T., Prasad P.N., Harvard University, US

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 [...]

Sub-wavelength metal nanostructure fabrication by parallel dip-pen nanolithography

Jang J-W, Nettikadan S., NanoInk Inc, US

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 [...]

Near-field infrared nanoscopy of phonon resonant silica and silica-coated goldnoparticles

Abate Y., California State University Long Beach, US

Single silica capped and uncapped gold nanoparticles are imaged using apertureless near-field optical microscopy (ANSOM) in the visible (λ=632 nm) and infrared frequencies (λ=10.7 µm). Identification of capped and uncapped particles with nanoscale spatial resolution [...]

ALD for sustainable future – building a cleaner world from sub-nanometer level

Toivola M., Pilvi T., Picosun Oy, FI

Atomic Layer Deposition (ALD) offers a superior way to coat highly conformal, uniform, pinhole and defect free thin films on even the most challenging nanoscale architectures. The technique is already widely in use in e.g. [...]

Boehmite nanometric with high surface area synthesized from a microwaves hydrothermal method

Quirino M.R., Oliveira M.J.C., Keyson D., Gama L., Bosco J., Federal University of Paraíba, BR

As the crystallization kinetics is enhanced by the introduction of the microwave hydrothermal method, the arm of this work was to produce and characterize boehmite by microwave-assisted hydrothermal. Boehmite nanostructure were synthesized by a hydrothermal [...]

Improve Environmental and Economic Performance with Streamlined Life Cycle Assessment (SLCA)

Shatkin J.A., Larsen W., CLF Ventures, Inc., US

Many new technologies offer significant improvements in environmental performance over existing approaches. Typically, there is some uncertainty about the health or environmental impacts, positive or negative, of new technologies, which can adversely affect their introduction [...]

Octadecylphosphonic acid Langmuir-Blodgett films and their modification by hyperthermal hydrogen projectile

Dey R., The university of waterloo, CA

We report on surface modification with hyperthermal hydrogen induced cross-linking (HHIC) technology on uniform and well-ordered octadecylphosphonic acid (OPA) Langmuir-Blodgett (LB) films on several surfaces, and on surface characterizations of its properties. The hyperthermal hydrogen [...]
