Tolerances Consideration in 3D Printing

Williams J., Wade A., Frostburg State University, US

The additive manufacturing laboratory at Frostburg State University utilizes three different 3D printers, studied and leaned the error in tolerance, and develop a method to approach parts with minimal tolerance error, and successfully produce the [...]

Layer-on-layer Assembly of Macroscopic 2D and 3D Carbon Nanomaterial Architectures

Patel S.C., Lalwani G., Alam O., Grover K., Qin Y-X, Sitharaman B., Stony Brook University, US

Although carbon nanomaterials are often labeled as the future replacement for silicon in electronics and a new generation of robust materials, there are major shortcomings in the assembly of carbon nanomaterials into higher order structures. [...]

Microstructures design of the assembly of monodisperse polystyrene microspheres via alternative current electric field

Ling L.T, Zhang J., Wang C.F., Chen S., Nanjing Tech University, CN

The assembly of monodisperse polystyrene microspheres under alternative current electric field was applied as a model system to study the assembling mechanism for nanomaterials. The microspheres of about 1-2 μm in diameter enable us to [...]

Reversible Long-Range Assemblies in Gold Nanoparticles – Liquid Crystal Composites: Molecular Dynamics of the Gold Capping Layer

Milette J., Toader V., Scheffer L.-P., Lennox R.B., Reven L., McGill University, CA

Highly miscible mesogenic ligand capped gold nanoparticles (AuNPs) [1] that produce reversible long-range assemblies in nematic and smectic liquid crystal (LC) [2-3] were recently developed by our group. At the isotropic-to-nematic phase transition of cyanobiphenyl [...]

Novel Nanofiber Anisotropic Conductive Films (ACFs) with coupled conductive particles for Ultra Fine Pitch Electronic Packaging Applications

Suk K-L, Paik K.W., KAIST, KR

In this study, a novel concept of nanofiber ACFs with conductive particles coupled in a nanofiber structure is suggested for ultra fine pitch applications. It was clearly demonstrated that novel nanofiber ACFs effectively suppressed the [...]

A 20 µm Movable Micro Mobile

Jeon J., Lee J.B., Kim M-J, The University of Texas at Dallas, US

We present design, fabrication, and characterization of an extremely small (20x14 µm) movable 3D micro vehicle. The micro mobile was fabricated using a combination of focused-ion-beam (FIB) for micro/nano parts production, atomic layer deposition (ALD) [...]

Scalability and Control of Electrophoretic Directed Assembly of Nanoparticles

Yilmaz C., Cha N-G, Somu S., Busnaina A., Northeastern University, US

The nanoscale directed assembly of nanoparticles has a many applications in biotechnology, energy, electronics and nanomaterials. Directed assembly of nanoparticles for biosensor devices, nanowire and interconnects are being conducted at the CHN. The nanoparticle based [...]

Engineering hybrid nanostructures with phage particles

Makowski L., Chen L., Argonne National Laboratory, US

Assembling complex structures comprising multiple, inorganic functional elements represents a significant engineering challenge. We have constructed hybrid nanostructures based on T7 and M13 phage and incorporating a variety of metals and metal oxides. Synthesis of [...]

Gas Phase Nanoparticle Integration

Barry C.R., Jacobs H.O., University of Minnesota, US

We report on two gas phase nanoparticle integration processes to assemble nanoparticles and other nanomaterials onto desired areas on a substrate. We expect these processes to work with any material that can be charged including [...]

Directed Growth of Carbon Nanotubes Utilizing Plasma Induced Surface Charging Voltage

Law J.B.K., Koo C.K., Thong J.T.L., National University of Singapore, SG

In this work, we present a method for directed lateral growth of CNTs between electrodes on a substrate during an in-situ CNT growth process, by utilizing plasma induced charging inherent in a Radio Frequency (RF) [...]
