This book was released on 2016 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advent of affordable miniaturized digital imaging devices has revolutionized many aspects of modern life. Most of these imaging devices still rely on old fashioned voice coil motors to displace the lens and form a sharp image. In order to decrease size and power consumption and increase focusing speed of small cameras, liquid tunable microlens alternatives have been proposed. Here, two types of focus tunable liquid microlenses are studied. The first type is a thermoelectrically actuated liquid microlens, and the second type uses an electrohydrodynamic actuator to move and center a liquid microlens. The first design demonstrates a sub-second response time, which makes it an agile device among thermally actuated microlenses. The second design harnesses an easy to fabricate, planar structure to realize a tunable microlens and center the liquid droplet. In both designs, focal length of the microlens has been measured. Moreover, optical aberrations of the thermally actuated microlens have been evaluated. In addition to liquid microlenses, a novel liquid tunable optical phase shifter is introduced. In this design, with the aid of an embedded electrowetting actuator, two liquid layers with different refractive indices are intermingled to create a tunable optical phase shifter that could be very useful in various optical imaging and instrumentation devices.

" Recognizing this potential, the White House Office of Science and Technology Policy (OSTP) and the Office of Management and Budget (OMB) have issued a joint memorandum to Federal agency heads that identifies nanotechnology as a research priority area for Federal investment in fiscal year 2001. This report charts "Nanotechnology Research Directions," as developed by the Interagency W orking Group on Nano Science, Engineering, and Technology (IWGN) of the National Science and Technology Council (NSTC). The report incorporates the views of leading experts from government, academia, and the private sector. It reflects the consensus reached at an IWGN-sponsored workshop held on January 27-29, 1999, and detailed in contributions submitted thereafter by members of the V. S. science and engineering community. (See Appendix A for a list of contributors.

Download or read book Soft Fibrillar Materials written by Jing Liang Li and published by John Wiley & Sons. This book was released on 2013-08-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: As one of the most important classes of soft materials, supramolecular materials are of a mixture of networks of molecular chains/fibrils and a liquid. These self-assembled fibrous/ molecular architectures exhibit various functionalities, ie. superhydrophobicity or superior mechanical strength, etc. and consist of the controllable structures. They can be functioned via micro/nano engineering, to have some particular added functions, ie. emission materials, tissue engineering scaffolds, bio imaging and sensing materials etc. They have therefore found broad applications in photography, cosmetics, food and petroleum industries and not the least in the biomedical sector where there is strong interest in these materials as drug delivery agents. The book covers the most important soft functional materials, including small molecule physical gels, silkworm silk and spider silk fibers and functional fibers, with respect both to the fundamentals and to development and engineering methods. It provides the reader with the necessary knowledge on the chemical and physical formation mechanisms of these materials and demonstrates that one can rationally design and tune the fibrillar networks so that the resulting materials exhibit the desired functionalities. This work is a must-have for all Materials Scientists, Polymer Chemists, Condensed Matter Physicists, and Biotechnologists working in this interdisciplinary field.
Download or read book Chemistry of Aluminium Gallium Indium and Thallium written by A.J. Downs and published by Springer Science & Business Media. This book was released on 1993-05-31 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boron has all the best tunes. That may well be the first impression of the Group 13 elements. The chemical literature fosters the impression not only in the primary journals, but also in asteady outflowofbooks focussing more or less closely on boron and its compounds. The same preoccupation with boron is apparent in the coverage received by the Group 13 elements in the comprehensive and regularly updated volume of the Gmelin Handbook. Yet such an imbalance cannot be explained by any inherent lack ofvariety, interest or consequence in the 'heavier elements. Aluminium is the most abundant metal in the earth's crust; in the industrialised world the metal is second only to iron in its usage, and its compounds can justifiably be said to touch our lives daily - to the potential detriment of those and other lives, some would argue. From being chemical curios, gallium and indium have now gained considerably prominence as sources of compound semiconductors like gallium arsenide and indium antimonide. Nor is there any want ofincident in the chemistriesofthe heavier Group 13 elements. In their redox, coordination and structural properties, there is to be found music indeed, notable not always for its harmony but invariably for its richness and variety. Thisbook seeks to redress the balance with a definitive, wide-rangingand up-to-date review of the chemistry of the Group 13 metals aluminium, gallium, indium and thallium.
