Nano-imprinting technology applied in pentacene films

Chang M-H, Chou W-Y, National Cheng Kung University, TW

The control of polymorphism in organic semiconductor films has attracted considerable interest for improvement in the device performance. In the present study, nano-imprinting technology is used to control polymorphism in pentacene film. Furthermore, we demonstrate [...]

Hybrid Poly(L-Lactide) (PLA) Nanofibers Incorporating POSS-Modified Multiwalled Carbon Nanotubes Prepared by Electrospinning

Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Jeong I., Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Shinshu University, JP

Organic–inorganic hybrid composites have attracted considerable attention because of their distinctive physical and chemical properties. Specifically, the multiwalled carbon nanotube (MWNT)-polymer composites among them has expected when uniform dispersion of the MWNTs in the polymer [...]

Effect of Size on Properties of Nano-Structured Polymers –Transition from Macroscaling to Nanoscaling

Lem K.W., Haw J.R., Lee D.S., Brumlik C., Sund S., Curran S., Smith P., Brauer S., Schmidt D., Konkuk University, KR

The growth in investment on the effect of size in nanoscience and nanotechnology has been astounding. Among the $12.4B spent in 2006 worldwide Nanotechnology research funding (Lux Research, 2007), at least 50%, that is >$6B, [...]

Soft plasma polymer coatings based on atomic polymerization

Cech V., Trivedi R., Lichovnikova S., Hoferek L., Brno University of Technology, CZ

Plasma polymerization is a thin film-forming process based on atomic polymerization. Plasma polymer films deposited from organosilicon monomers constitute a special class of dielectric coatings with controllable organic/inorganic character and cross-linking that enable optimization of [...]

Development of Durable Nanostructured Superhydrophobic Self-Cleaning Surfaces in Glass Substrates

Jiang Y.D., White M., Hunt A.T., Kitada M., Fitz T., nGimat Co., US

Superhydrophobic self-cleaning surfaces have wide applications in architectural and automotive windows and solar panels, etc. Many existing hydrophobic coatings either have low transmittance which is not suitable for windows or not as hydrophobic as lotus [...]

Wicking Study of Nanostructured Titania Surfaces for Flat Heat Pipes

Ding C., Bogorzi P., Sigurdson M., Soni G., Meinhart C., MacDonald N.C., university of california, santa barbara, US

We report a wicking material based on nanostructured TiO2 (NST) for the application of flat heat pipes. This wicking material is formed by oxidizing Ti pillar structures in H2O2 solution. The NST surfaces shows nano-scale [...]

Conformational analysis of alternating copolymers and their association into nanoarchitectures

Chan A.S.W., Groves M., Malardier-Jugroot C., Royal Military College of Canada, CA

Our research focuses on the characterization of the association and the properties in aqueous solution of nano-structures, particularly on nanotubes composed of amphiphilic alternating copolymers. These copolymers constitute a pH sensitive hydrophilic group (maleic anhydride) [...]

A Markedly Cntrollable Adhesion of Superhydrophobic Sponge-like Nanostructure TiO2 Films

Lai Y., Lin C., Huang J., Zhuang H., Sunb L., Nguyen T., Xiamen University, CN

A method consisting of electrochemical anodization and self-assembling of hydrophobic-hydrophilic mixture has been employed to fabricate superhydrophobic sponge-like nanostructured TiO2 surfaces with remarkably controllable adhesion. Water adhesion ranged from ultra-low (5.0 N) to very high [...]

Hypertransparent Nanostructured Superhydrophobic Self-Cleaning Coatings on Glass Substrates

Jiang Y.D., Smalley Y., Paris H., Hunt A.T., nGimat Co., US

Self-cleaning surfaces have wide applications in architectural and automotive windows and solar panels, etc. The development of superhydrophobic surfaces was inspired by observation of lotus and other plant leaves. Many existing hydrophobic coatings either have [...]

Simulation and Fabrication of Large Area 3D Nanostructures

Bogart K.H.A., El-kady I., Grubbs R.K., Rahimian K., Sanchez A.M., Ellis A.R., Wiwi M., McCormick F.B., J.-L. Shir D., Rogers J.A., Sandia National Laboratories, US

Three-dimensional (3D) nano-structures are vital for emerging technologies such as photonics, sensors, fuel cells, catalyst supports, and data storage. The Proximity-field nanoPatterning1 method generates complex 3D nanostructures using a single exposure and development cycle. Exposure [...]
