CMU Micromachining

CurtisEllzey — Tue, 22 Jul 2008 14:23:00 GMT
At Carnegie Mellon University, Professor Burak Ozdaganlar's research focuses on micro- and meso- scale manufacturing. The interest in small components and small features has been rapidly increasing. Biotech, biomedical, optics, aerospace, military, defense, security, automotive, microelectronics packaging, and communication industries have been increasingly demanding miniature products and miniature features in larger products. This demand mainly arises from the potential advantages of miniaturization: multiple functionality; weight, space, and material savings; strategic placement/configuration availability; increased reliability; and other, currently non-existent capabilities. The development of complex micro devices necessitates efficient and economical creation of sophisticated mechanical structures with 3D geometrical features made from a diverse selection of materials.

Ferrofluids

CurtisEllzey — Thu, 17 Jul 2008 14:56:00 GMT
A ferrofluid is a liquid which becomes strongly polarized in the presence of a magnetic field. It is a colloidal mixture comprising extremely small magnetic particles suspended in a liquid. Ferrofluids are composed of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid, usually an organic solvent or water. The ferromagnetic nano-particles are coated with a surfactant to prevent their agglomeration. Research of colloidal suspensions of fine magnetic particles at Carnegie Mellon University has found applications in biomed sectors.

RF Plasma Torch Synthesis

CurtisEllzey — Wed, 16 Jul 2008 13:20:00 GMT
At Carnegie Mellon University, Prof. McHenry's recent efforts have evolved from the study of carbon-coated magnetic nanocrystals produced by the Kratschmer-Huffman carbon arc method and fine particle magnetism in the same. This lead to studies of the plasma torch synthesis of metallic, C-coated, oxide, carbide and nitride nanoparticles. Most recently reactive gas plasma torch synthesis has been used to produce nanocrystalline ferrite materials for high frequency applications. The surface structure, and its influence on properties, is being studied in faceted ferrite nanoparticles.

Cut Core Power Transformer

CurtisEllzey — Tue, 15 Jul 2008 16:09:00 GMT
Professor Michael McHenry's team of researchers at Carnegie Mellon University have developed nanocomposites for applications with high permeability requirements and with needs for large inductions at high temperatures. Specifically they have developed soft magnetic alloys that exhibit high magnetic induction at temperatures above current operating ranges for commercial devices. Soft magnetic materials face demanding requirements from new, high-performance electronic and power distribution systems. The new systems must operate in high-temperature and high-frequency regimes that are inaccessible to conventional crystalline and amorphous magnetic materials. The need for increased energy efficiency requires reduced power loss from inductive components. Nanocrystalline magnetic materials hold promise for meeting these requirements without resorting to the trade-offs needed when using conventional materials.

CMU Plasmonics

CurtisEllzey — Thu, 19 Jun 2008 15:13:00 GMT
Interdisciplinary research addressing fundamental issues and questions, a systems level approach, along with close ties to industry, all brought together to yield relevant and timely research is the formula for success in the ECE Department at Carnegie Mellon. Under the direction of Elias Towe, research includes plasmonics. In physics, a plasmon is a quantum of a plasma oscillation. The plasmon is the quasiparticle resulting from the quantization of plasma oscillations just as photons and phonons are quantizations of light and sound waves, respectively. Thus, plasmons are collective oscillations of the free electron gas density, often at optical frequencies. Plasmons have been considered as a means of transmitting information on computer chips, since plasmons can support much higher frequencies (into the 100 THz range, while conventional wires become very lossy in the tens of GHz). Plasmons have also been proposed as a means of high-resolution lithography and microscopy due to their extremely small wavelengths. Both of these applications have seen successful demonstrations in the lab environment. Finally, surface plasmons have the unique capacity to confine light to very small dimensions which could enable many new applications.
