Selected AbstractsUltrasonic Nanofabrication with an AFMIMAGING & MICROSCOPY (ELECTRONIC), Issue 4 2007Nanomanipulation, Ultrasound Facilitates Nanolithography Abstract Ultrasonic AFM may improve fabrication technologies on the nanometer scale. In the presence of ultrasonic vibration, hard surfaces can be indented and scratched with the tip of a soft cantilever, due to its inertia. Ultrasound reduces or even eliminates friction, and hence modifies the tip-nanoparticle-surface interactions in AFM manipulation. The subsurface sensitivity of the technique makes feasible the purposed manipulation of subsurface nanoscale features by ultrasonic actuation. [source] Parallel Processing: Design /PracticeARCHITECTURAL DESIGN, Issue 5 2006David Erdman Abstract In the late 1990s servo emerged as a young design collaborative embracing new forms of distributed practice as enabled by the advent of telecommunications technologies. In this section, David Erdman, Marcelyn Gow, Ulrika Karlsson and Chris Perry write about how these organisational principles are at work not only in the context of their practice, but in the design work itself, which stretches across a variety of design disciplines to incorporate areas of expertise particular to information and interaction design, as well as a number of manufacturing and fabrication technologies. Many of servo's projects have focused on small-scale interior infrastructures, typically in the form of gallery installations, furniture systems and exhibition designs. This particular scale has allowed the group to focus on the development of full-scale prototypes, exploring a wide range of potential innovations at the point of integration between various technological and material systems.

[source] Computatonal Intelligence: The Grid as a Post-Human NetworkARCHITECTURAL DESIGN, Issue 5 2006Philippe Morel Abstract Research and design collaborative EZCT Architecture & Design Research has adopted grid computing to produce a series of furniture systems and other small-scale prototypes using genetic algorithms in combination with automated fabrication technologies. Here, cofounder Philippe Morel relates this design practice to the broader technical and social implications of various grid-computing projects, such as the online organisation Folding@Home, which utilises grid computing and distributed communities for the production and exchange of postindustrial knowledge. He argues that these ,knowledge farms' which create an ,ambient factory', are perhaps the ultimate form of social-economic production, transforming not only the evolution of design but of the communities that produce and eventually consume its products.

[source] Energy Transfer in Fluorescent Nanofibers Embedding Dye-Loaded Zeolite L CrystalsADVANCED MATERIALS, Issue 10-11 2009Varun Vohra Electroluminescent polymeric nanofibers embedding dye-loaded zeolite L crystals are prepared. By exciting the polymer nanofiber, the energy is transferred to the fluorescent dyes inside the zeolite L channels through a two-step Förster resonant energy transfer process. This study opens new perspectives in the field of low-cost fabrication technology of flexible nanoscale OLEDs. [source] Multilayer Construction with Various Ceramic Films for Electronic Devices Fabricated by Aerosol DepositionINTERNATIONAL JOURNAL OF APPLIED CERAMIC TECHNOLOGY, Issue 6 2006Hironori Hatono Aerosol deposition (AD) is applicable as a fabrication technology for microstructures comprising different materials. We used this method for electronic devices that consist of ceramic films and metal electrodes. Various ceramic thick films (5,50 ,m thickness), for example, Al2O3, 2MgO·SiO2, and BaTiO3, were deposited on substrates using room-temperature aerosol deposition. The dielectric constant of BaTiO3 was 78 at 1 MHz. Multilayer constructions with ceramic films and copper electrodes were obtained using aerosol deposition and sputtering. During deposition, photoresist film masks were applied to produce patterns of ceramic films and connections between upper and lower electrodes through the ceramic films. [source] Investigation of AlGaN/GaN HEMTs on Si Substrate Using BackgatingPHYSICA STATUS SOLIDI (C) - CURRENT TOPICS IN SOLID STATE PHYSICS, Issue 1 2003M. Marso Abstract The influence of a substrate voltage on the dc characteristics of an AlGaN/GaN HEMT on silicon (111) substrate is investigated. This effect, known as backgating, is used to study traps that are located between substrate and 2DEG channel. The transient of the drain current after applying a negative substrate voltage is evaluated for measurements with and without illumination. Several trap contributions are resolved by measurements at different photon energies. A photocurrent is observed up to 600 nm wavelength. Up to this wavelength the backgating effect can be compensated and the drain current restored by a short light pulse. The experiments are performed on completed HEMTs, allowing investigation of the influence of device fabrication technology. [source] | ||||||||||
