Self Aligned Multi-Layer Nano-Gap Electrodes for Fluidic and Magnetic Assembly of Carbon Nanotubes

Shim J.S., Yun Y.H., Schulz M.J., Ahn C.H., University of Cincinnati, US

A self aligned nano-scale gap was fabricated using conventional optical lithography, and applied for the assembly of a carbon nanotube (CNT). The new technique enables the formation of a sub-micron gap between self-aligned electrodes with [...]

Self-assembled Manganese Dioxide Thin Films as Novel Electrode Material for the Fabrication of Thin–Film Supercapacitors

Cem Pang S., Wee B.H., Universiti Malaysia Sarawak, MY

Self-assembled manganese dioxide thin films were being deposited directly onto metalized plastic supporting substrates by a novel horizontal submersion process which entailed spontaneous self-assembly of preformed manganese dioxide nanoparticles under optimized deposition conditions. Desired film [...]

Self-Assembly of Polymers and NanoParticles in Personal Care Products

Berg M.C., Suddaby N.A., Soane D., Soane Labs, US

Soane Labs develops and applies nanotechnology and advanced polymer chemistry to the personal care industry trough novel colorants and high-affinity polymers. By controlling the spontaneous self-assembly of polymers and nanoparticles at interfaces, the color, look, [...]

Assembly of Nanoscale Scaffolds from Peptide Nucleic Acids (PNA)

Husk Jr. T., Bergstrom D.E., Purdue University, US

Deoxyribonucleic acid or DNA has been demonstrated to be a useful scaffold for self-assembling nanomaterials. Peptide nucleic acids, or PNA, which retains the nucleic acid bases adenine, cytosine, guanine, and thymine on a pseudo-peptide backbone [...]

Towards rational de novo design of peptides for inorganic interfaces

Biggs M.J., University of Edinburgh, UK

Proteins at inorganic interfaces occur across science, technology and nature – protein arrays, prostheses such as stents and artificial heart valves, biomimetic assembly of nanoparticles, and anti-freeze proteins are just a few examples from many. [...]

Building Micro-Robots: A path to sub-mm3 autonomous systems

Reid J.R., Vasilyev V., Webster R.T., US Air Force Research Laboratory, US

A process for fabricating sub-cubic millimeter, fully autonomous micro-robots is presented. Details of the process flow and intial prototype structures are demonstrated. In addition, the design of an electrostatic actuator array for moving the robot [...]

Synthesis and Self-Assembly of Biodegradable Poly(ethylene oxide)-b-Polycaprolactone (PEO-b-PCL) Diblock Copolymers

Li G., Ghoroghchian P., Qi W., Christian N., Frail P.R., Hammer D.A., Therien M.J., Carestream Health Inc., US

A series of amphiphilic poly(ethylene oxide)-b-polycaprolactone (PEO-b-PCL) diblock copolymers with various PEO blocks (number-average molecular weight (Mn): 750~5800), PEO weight fraction (fPEO) from 7.7% to 33.3%, and Mn of the copolymers from 3.6k to 57k, [...]

Myelin-mimetic lipid multilayers

Iyer S., Dattelbaum A., Majewski J., Shreve A., Los Alamos National Laboratory, US

The myelin sheath is among nature’s most fascinating nanoscale assemblies. In spite of its critical role in physiology, several questions on the structure-function relationship of myelin and its components remain unanswered. This is chiefly due [...]

Exploring the behavior of concentrated collagen, approaches to tailor biomimetic materials

Gobeaux F., Mosser G., Anglo A., Panine P., Davidson P., Giraud-Guille M.-M., Belamie E., Ecole Pratique des Hautes Etudes, FR

Dense ordered collagen matrices can be obtained by fine tuning the electrostatic interactions in highly concentrated solutions of type I collagen. Such biomimetic fibrillar materials have a high application potential in the field of tissue [...]

Guided Self-Assembly of Block-Copolymer Nanostructures

Karim A., Berry B.C., Kim H-C, Kim S., Zhang X., Bosse A.W., Lacerda S.H., Yager K.G., Jones R.L., Douglas J.F., Briber R.M., Kim H-C, Kim S., NIST, US

A primary limitation of block copolymer films as templates for next generation electronic or data storage devices is the prohibitively long times required for thermally driven self-assembly and defect annihilation and long range order development. [...]
