No full textNanomanufacturing Summit 2012: Highlighting Nanotechnology Innovation, Commercialization, and Manufacturing
No full textA host of cross-cutting federal, state, and regional initiatives have recently been announced with targeted objectives that include accelerating the innovation cycle for U.S. manufacturing and enhancing the connections between academic research and industry driven commercialization. In establishing such public-private partnerships, a key goal is to provide the platform for industry to leap the "Valley of Death", the proverbial chasm that lies between innovations within small businesses and academia, and commercial scale-up and manufacturing. Prime examples of these initiatives include the Advanced Manufacturing Partnership (AMP), announced last year by the Obama administration, and the National Network for Manufacturing Innovation (NNMI) that may include up to 15 Institutes within the U.S. targeting different sectors of manufacturing innovation. Staying on course with this model, the administration this week announced a 26 Million Multi-agency Competition to Strengthen Advanced Manufacturing Clusters Across the Natio

No full textNanomanufacturing processes are typically unique methods employed to control the shape, features, size, and morphology of materials in order to achieve some value-added functionality. Depending on the targeted objectives, numerous approaches and materials could be explored to reach the final goals. While such process research and development may be exciting and educational to researchers, often times this results in extensive cost and time delays in reaching a scalable nanomanufacturing path that could lead to commercialization of nanotechnology-enabled products. This is of particular importance to industry where it is critical to identify and optimize the nanomanufacturing process development cycle, enabling a more competitive innovation ecosystem. As an added resource in nanomanufacturing process R&D, InterNano hosts a small but growing Process Database, or a knowledge base of techniques for processing nanoscale materials, devices, and structures. The entries include step-by-step descriptions, images, notes on methodology and environmental variables, and associated references and patent information. The purpose of the Process Database is to enable sharing of appropriate process knowledge across laboratories. The National Nanomanufacturing Network (NNN) is working to facilitate the access to and documentation of a rich and representative collection of nanomanufacturing processes, and encourages the nanomanufacturing community to contribute to this collection.

Thermoreflectance Microscopy: Metrology for Optoelectronic Devices
No full textThe luminance and lifetime of OLEDs decrease dramatically with increased device operating temperature due to selfheating; this problem is particularly severe in OLEDs operated at high-brightness conditions. For stand-alone OLEDs, selfheating leads to measured rises in average temperatures of up to 60°C, with local temperature rises of up to 200°C, reducing lifetime by 20x or more. Thermoreflectance imaging, can be used through glass to characterize the thermal performance of an operating OLED and inspect the temperature profile spatially to help increasing the lifetime of high brightness OLEDs with better thermal design
Roll-to-Roll Fabrication of Flexible Low-operating Voltage Organic FETs Using Solution-based Hybrid High-K Dielectrics
No full textOrganic field effect transistors (OFETs) are key for flexible, lightweight, and inexpensive electronic devices. Low-voltage operation of OFETs is necessary for many practical applications and all solution-based, low-temperature processes are desirable as they provide a significant cost advantages for scaling to large area roll-to-roll fabrication processes. To meet these challenges the CHM has developed solution-based high-k dielectric coatings consisting of zirconia (ZrO2) nanoparticles in a polymer composite

No full textMechanical Properties of End-Linked PEG/PDMS Hydrogels
No full textPoly(ethylene glycol) (PEG)/polydimethylsiloxane (PDMS) hydrogels were synthesized by cross-linking norbornene end-functionalized polymers with a tetrafunctional thiol using thiol-norbornene chemistry. The swelling capacity and mechanical properties, including the Young's modulus (E) and fracture toughness (G(c)), of the hydrogels were characterized and quantified as a function of the volume fractions of PEG and PDMS. E and G(c) increased simultaneously with the volume fraction of PDMS. The moduli of the hydrogels were quantitatively described and predicted as a function of the volume fraction ratio of PEG to PDMS using the Voigt and Reuss models. The fracture toughness was well described by the Lake-Thomas theory at low volume fractions of PDMS. As the volume fraction of PDMS increased, PDMS the hydrogels but also contributed to hydrogel toughness. not only controlled the swelling capacity of the hydrogels but also contributed to hydrogel toughness
