Antimicrobial Fabrics Coated with Nano-Sized Silver Salt Crystals

Tessier D., Radu I., Filteau M., Center for Textile Technologies, CA

Antimicrobial fabrics find many technical applications in medical, hygiene, protection, sport, and industrial markets. However, antimicrobial fabrics differ in biocidal performance and durability. For example, such fabrics are used in wound dressings or bio-hazard protective [...]

Recent Applications of Mesoscale Modeling to Nanotechnology and Drug Delivery

Maiti A., Wescott J., Kung P., Goldbeck-Wood G., Accelrys Inc., US

Technologically important nanomaterials come in all shapes and sizes. They can range from small molecules to complex composites and mixtures. Depending upon the spatial dimensions of the system and properties under investigation, computer modeling of [...]

Control Synthesis of Functional Nanoassemblies using Langmuir-Blodgett Method

Wang H.-L., Tang Z., Gao Y., Magyar R.J., Tretiak S., Shreve A.P., Los Alamos National Laboratory, US

We strive to design syntheses of a series of amphiphilic molecular building blocks that can self-assembled at the air-water interface to form 2D and 3D nanostructures with specific opto-electronic properties. Compression of these molecular building [...]

Nanostructured Fluids, Soft Materials, and Self Assembly

Fabrication of Self Organized Copper Nanostructures on Structureless Surfaces

Kunz R., Kipp L., Skibowski M., Adelung R., Christian-Albrechts-University, DE

An easy way to cover large areas with nano-or microstructures is self-organization. Against intuition, we claim that structureless crystals in terms of surface features are well suitable for self organized structuring on the nano-and micrometer [...]

Controlled Synthesis and Directed Assembly of Vertically Aligned Carbon Nanofibers for Functional Nanoscale Devices

Merkulov V.I., Melechko A.V, Guillorn M.A., McKnight T.E., Austin D.W., Hale M., Zhang L., Yang X., Hensley D.K., Subich T., Doktycz M.J., Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US

The controlled synthesis and directed assembly of materials at the nanoscale remain two of the most difficult challenges for the realization of functional nanoscale devices. For example, while there has been a great deal of [...]

Oriented Molecular Sieve Films by Heteroepitaxial Growth

Jeong H-K, Krohn J., Sujaoti K., Tsapatsis M., Univ. of Massachussetts at Amherst, US

Potential uses of crystalline molecular sieves as selective membranes, membrane reactors, chemical sensors, optical devices as well as in other new applications rely on the ability to grow them as films.1-12 The crystallinity of these [...]

Fabrication of 20 nm Embedded Longitudinal Nanochannels Transferred from Metal Nanowire Patterns

Choi D.S., Yang E.H., Jet Propulsion Laboratory, US

The traditional electron beam lithography and more recently developed focused ion beam (FIB) milling/lithography techniques have been exploited for generating exposed nanometer-size nanochannels. An additional process step of sealing exposed nanochannels cant be avoided to [...]

Near-Field Nanomodification of Thin Films Using Femtosecond Laser and Atomic Force Microscope

Chimmalgi A., Choi T.Y., Grigoropoulos C.P., Wan D., Komvopoulos K., University of California-Berkeley, US

Nanostructures, which have characteristic dimensions that are difficult to achieve by conventional optical lithography techniques, are finding ever-increasing applications in a variety of fields. For applications incorporating nanodevices to gain widespread acceptance, high resolution, reliability [...]

AFM Anodization Studied by Spectromicroscopy

Lazzarino M., Mori G., Ercolani D., Ressel B., Colli A., Sorba L., Locatelli A., Cherifi S., Ballestrazzi A., Heun S., Laboratorio TASC INFM, IT

The fabrication of state-of-the-art semiconductor nanostructures is of great interest both for fundamental physics and device applications. Besides the traditional lithography techniques, local anodic oxidation by atomic force microscopy (AFM) is emerging because of its [...]
