Comparing Biocompatibility of Titanium Orthopaedic Implants With and Without an Ultra-thin Coating of TiO2 by Ion Beam Assisted Deposition

Miralami R., Namavar F., Thiele G.M., Sharp J.G., Garvin K.L., University of Nebraska Medical Center, US

Introduction: Annually, more than one million Americans undergo arthroplastic surgeries, and by 2030 the projected number will exceed more than four million [1]. Thus, there is a serious need to accommodate such overload. It has [...]

Comparison of carbon nanotube data collected using two microscopy methods: dark-field hyperspectral imaging and electron microscopy

Eastlake A.C., Geraci C.L., NIOSH, US

Currently, the National Institute for Occupational Safety and Health (NIOSH) Nanotechnology Research Center uses a modified version of the NIOSH Manual of Analytical Method 7303 (Elements by ICP) and electron microscopy (either scanning or transmission) [...]

A Focused Super-Continuum Solar Simulator for Illuminated Solar Cell Microscopy

Dennis T., National Institute of Standards and Technology, US

The design and application of a novel, focused solar simulator based on a high-power, super-continuum laser is described. We used the simulator to create micrometer-scale spatial maps of full-spectrum optical beam induced current (FS-OBIC) in [...]

The influence of technique on the measured particle size distribution of complex nanoparticle systems

Jämting Å.K., Roy M., Catchpoole H.J., Lawn M., Babic B., Coleman V.A., Herrmann J., National Measurement Institute Australia, AU

Accurate and reliable characterization of nanoparticles is crucial for both industrial applica-tions and studies of their toxicological and environmental impacts. Particle size distribution (PSD) has been widely recognised as one of the key parameters that [...]

Applications Developments with the Helium Ion Microscope

Scipioni L., Notte J., Carl Zeiss SMT, Inc., US

The helium ion microscope is offering new windows into nano-scale imaging. Unique sample interaction dynamics allow new types of sample information to be gathered. Some fundamental advantages conferred by probing a surface with a helium [...]

In-plane Vibration Measurements of Micro Scale Devices Using Sub-Pixel Image Registration Algorithms and Stroboscopic Illumination

Buyukyazi T., Basdogan I., Koc university, TR

Rapid developments in micro devices created a necessity for reliable testing methods for characterization. There are several methods for vibration measurements but most of them use out-of-plane displacements. However, in most cases in-plane measurements are [...]

Control of Micro-Fluidic Flow using 3D Features

Bullock L.E., Robinson A.E., University of Massachusetts Dartmouth, US

Lab-on-a-Chip sensors require precise control and mixing of samples, reagents and buffers. This paper will present new techniques for using Excimer Laser, micro-machined, three-dimensional (3D) channel and well features to pump and control fluids in [...]

Nano-Lithography in Ultra-High Vacuum (UHV) for Real World Applications

Gilsinn J., Zhou H., Damazo B., Fu J., Silver R., NIST, US

As nano-lithography technology improves, more companies and research groups have the capability to create nano-scale structures. Scanning tunneling microscopes (STMs) are commonly used to create these structures and evaluate them afterward. One difficulty is that [...]

Structural and Mechanical Properties of Double Wall Carbon Nanotubes

Bacsa R.R., Bacsa W.S., Flahaut E., Laurent Ch., Peigney A., Puech P., Bacsa R.R., Bacsa W.S., LPST Université Paul Sabatier, FR

Narrow diameter double walled carbon nanotubes can now be grown by the catalytic chemical vapor deposition process with high yield. Double walled carbon nanotubes are the molecular analogs to coaxial cables and they can also [...]
