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

Microcap Selective Packaging through Flip Chip Alignment

Chao C.H., Pan C.T., National Sun Yat-Sen University, TW

In this study, the technique of microcap selective bonding for 3-D microstructures using MEMS processes was presented. The flip-chip assembly was successfully demonstrated that the microcap transferred on the selective area of the host substrate [...]

Interfacial Instabilities in Multilayer Extrusion

Ho K., Lee J.S., Viriyabanthorn N., Sung C., Barry C.M.F., Mead J.L., University of Massachusetts-Lowell, US

Polymeric alternating multilayer laminates have been prepared by coextrusion, utilizing a specially designed feedblock to combine the two incoming materials from different extruder. Layer multiplying elements (LME) were used to split the melt stream, divide [...]

Processing Parameters Affecting Nanoinjection Molding

Srirojpinyo C., Yoon S-H, Lee J., Sung C., Mead J.L., Barry C.M.F., University of Massachusetts-Lowell, US

Although micro parts and features are routinely molded, the performance of polymer melts is not well understood when the part wall thickness is less than 1 mm. In this study, the effects of molding conditions [...]

Investigation of Tooling Surfaces on Injection Molded Nanoscale Features

Yoon S-H, Srirojpinyo C., Lee J., Sung C., Mead J.L., Barry C.M.F., University of Massachusetts at Lowell, US

The composition and surface properties of tooling materials become more critical as the size of the molded features decreases [1, 2]. This work investigates the effect of tooling surfaces with micro and nanoscale features. These [...]

Nano-Lithography in Ultra-High Vacuum (UHV) for Real World Applications

Gilsinn J., Zhou H., Damazo B., Fu J., Silver R., NIST, US

As nano-lithography technology improves, more companies and research groups have the capability to create nano-scale structures. Scanning tunneling microscopes (STMs) are commonly used to create these structures and evaluate them afterward. One difficulty is that [...]

Fabrication of Metallic Nano-stamper and Replication of Nano-patterned Substrate for Patterned Media

Kim Y., Kim Y.J., Lee N., Kim Y., Kim Y.J., Kang S., Yonsei University, KR

With increasing demand for ultra high-density information storages, patterned media has received much attention as a solution to overcome the limits of conventional continuous magnetic media. Current methods to fabricate the patterned media are to [...]
