Structural fingerprinting of nano-crystals based on high resolution transmission electron microscopy imaging: challenges and perspectives

Moeck P., Moon B., Rouvimov S., Portland State University, US
The methods for structure identification and analysis of nanocrystalline particles are in high demand for nanotechnology and nanofabrication, areas that require fast, reliable and robust metrologies for nanometer-sized objects. High-resolution (HR) transmission electron microscopy (TEM) [...]

Effect of Rare Earth Doping on Magnetic Properties of Cobalt Ferrite Nanocrystals

Cedeño-Mattei Y., Osorio-Cantillo C., Perales-Perez O., Uwakweh O.N.C., University of Puerto Rico-Mayagüez, PR
Cobalt ferrite (CoFe2O4) is a highly anisotropic magnetic material due to the magnetocrystalline anisotropy contribution from Co2+. The addition of foreign cations of different oxidation states, substituting Co2+ or Fe3+, can lead to an atomic [...]

Nano-Biotechnology toward Diagnostic Industry: Obstacles and Opportunities

Esfandyarpour H., Stanford, US
Biosensing of infectious agents should be ideally real-time, multiplexed, sensitive and specific. While no single device thus far have demonstrated superiority with respect to all these qualities, many of the upcoming nanomaterial-based sensors described in [...]

Characterization of CdSe Nanocrystals and their Interaction with Micellar Aggregates by Means of Capillary Electrophoretic Techniques

Oszwaldowski S.O., Roberts K.P., Tonev A., Vasicek L., The University of Tulsa, US
Characterization of nanocrystals is crucial for the development of many chemical methods based on this technology. For this, there are several techniques, mainly microscopic, and recently capillary electrophoretic techniques, that have been proposed. In our [...]

Optimization of Magnetic Properties in Cobalt Ferrite Nanocrystals

Cedeño Y., Perales-Perez O., Roman F., Singhal R., Tomar M.S., University of Puerto Rico, Mayaguez Campus, PR
Among the various ferrite materials for magnetic recording applications, cobalt ferrite (CoFe2O4) possesses excellent chemical stability and good mechanical hardness. Furthermore, the large positive first order crystalline anisotropy constant has made this ferrite a promising [...]

Colloidal Structure-directing-agent-free Hydroxy-sodalite Nanocrystals

Wang H.T., Yao J.F., Monash University, AU
This presentation describes a unique approach to the synthesis of colloidal structure-directing-agent-free hydroxy-sodalite nanocrystals by using silicalite nanocrystals as a silica source.Under the aid of TPAOH molecules trapped in the dried silicalite nanocrystals, the silicalite [...]

Three-dimensional Structure of Nanocrystals from High-energy X-ray Diffraction and Atomic Pair Distribution Function Analysis

Petkov V., Central Michigan University, US
3-D, nanocrystal, high-energy, X-ray, diffraction, atomic pair, distribution function analysis

Strain and Structure in Nanocrystals

Bae Y., Caflisch R.E., University of California, Los Angeles, US
Layered nanocrystals consist of a core of one material surrounded by a shell of a second material. Because of the small size of these systems, their atomic structure is epitaxial in many cases. Lattice mismatch [...]

Room-Temperature Synthesis and Characterization of Highly Monodisperse Transition Metal-Doped ZnO Nanocrystals

Parra-Palomino A., Perales-Perez O., Ruiz-Mendoza A., Singh S.P., Tomar M.S., University of Puerto Rico, PR
We present here the results of our current efforts on size-controlled synthesis of bare and Mn- and Co-doped ZnO nanocrystals. Stable suspensions of these materials were produced in ethanol solutions at room-temperature. XRD characterization of [...]

Nanoscience and Nanotechnology:Two New Exciting Fields for Future Display Applications

Yaniv Z., Applied Nanotech, Inc., US
Though just two years ago nanoparticles and nanotechnology were little more than a blip on the industrial applications radar, over 1 billion in annual venture capital is expected to be invested in the field in [...]
