Enabling Nanofabrication through Dip Pen Nanolithography™

Dip Pen Nanolithography, DPN™, was discovered in the laboratory of Dr Chad Mirkin at Northwestern University leading to the founding of NanoInk, Inc. with a mission to develop, manufacture and advance the process of DPN [...]

Anticipating the Public Backlash: Public Relations Lessons for Nanotechnology from the Biotechnology Experience

Matsuura J.H., University of Dayton School of Law, US

Public concern about the safety of nanotechnology is growing. Whether rationally based, or not, that concern can impede research and commercialization in the nanotechnology industry. This risk parallels problems already encountered by the biotechnology industry, [...]

Novel Approach to Circuit Board Testing

Wright R.G., Kirkland L.V., Zgol M., Adebimpe D., Keenan E., Mulligan R., GMA Industries, Inc., US

Fast, accurate, and inexpensive identification of failed integrated circuits on electronic circuit boards presents a major challenge for the electronic testing industry. In this paper we describe research and development efforts in the application of [...]

Atomic Holographic Optical Storage Nanotechnology

Thomas M.E., Colossal Storage Corp., US

Colossal Storage Inc. has exclusive license patent rights on new ways of non - contact reading and writing with non destructive reading of information to a ferroelectric molecule. These methods will be used to develop [...]

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 [...]

Mechanical Parameter Extraction of Thin-Film Coated Materials

Li Y., Tseng K.K., Vanderbilt University, US

Materials coated with thin-films have become popular in many advanced applications. The thin layer of high-strength coating can improve the performance of the material. However, challenges arise when characterizing or extracting mechanical parameters for this [...]

Phase Identification and Elastic Property of Blend Copolymer Characterized by Force Modulation Microscopy and Force-Distance Curve

Kang B., Lee J.S., Pham L., Sung C., University of Massachusetts-Lowell, US

The technique of polymer blending has been used to create new types of polymers with desirable properties in the past decade. Force Modulation Microscopy (FMM) provides a local contrast due to the local elasticity difference [...]
