Large-area nanowire photodetection circuitry

Nanowires are unique among all kind of nanostructures regarding their extraordinary physical and material characteristics, besides unlimited flexibility in terms of their method of production, size, composition and geometry. It is therefore striking that industrial scale utilization of these magnificent nanostructures has not emerged considerably yet. Bridging the nanoscale with the macroscopic world with high throughput remains one of the biggest challenges of the nanotechnology, despite many incisive and elaborate …

Prestigious European Research Council grant awarded to Dr. Bayindir

Professor Mehmet BAYINDIR, asistant director of UNAM and faculty member of Physics Department, has been awarded ERC Starting Grant which was created to encourage “pioneering frontier research in any field of science, engineering and scholarship.” The ERC grant of € 1.5 million is for five years. Dr. Bayindir’s proposal focuses on the development of a novel fabrication technique (top-to-bottom iterative size reduction) in nanotechnology.

Coloring nanowires without colorants

Something is of a particular hue usually because it is intrinsically that color, like the leaves of green plants. But equally likely the color of an object, small like a soap bubble or a bird feather, or immense like the firmament, appear to be of a particular color because it simply reflects (or to be precise scatters) that wavelength of light. We use the former pigment colors when we paint …

A new fabrication technique reported in Nature Materials

The new fabrication technique, reported in Nature Materials by Bayindir research group at UNAM-National Nanotechnology Researsh Center, Bilkent University is essentially a size reduction technique. Controlled thermal size reduction is repeated iteratively until a macroscopic rod is scaled down to nano sizes radially while elongated axially. In this way a variety of semiconducting, piezoelectric and polymer nanowires and tubes can be produced. Millions of ordered indefinitely long nanowires, nanotubes, and …

Digital photonic nose for machine olfaction

Researchers at UNAM developed an infrared absorption based photonic nose that uses photonic bandgap fibers to differentiate and assign unique binary codes to odorous molecules, opening a new path for photonic based olfactory sensors. Machine olfaction research aspires to mimic the exquisite sense of smell in mammals, using arrays of cross responsive sensors backed with sophisticated pattern recognition algorithms for the differentiation of thousands of complex odors. Each odorant, with …

President Abdullah Gül visits Bayindir Group Laboratories

President Abdullah Gül stopped by our laboratories during his visit to UNAM-Institute of Materials Science and Nanotechnology on Wednesday, September 02, 2009. The President was briefed about projects on microfluidic metamaterials, tumor therapy with infrared lasers, and explosive sensing materials by graduate students. Prof. Dr. Mehmet Aydin and Dr. Cevdet Yilmaz (Ministers), Kemal Madenoğlu (Undersecretary of State Planning Organization), Prof. Dr. Nüket Yetiş (President, Tübitak, The Scientific and Technological Research …
