Preparation and Characterization of Various Nanofluids

Williams W.C., Bang I.C., Forrest E., Hu L.W., Buongiorno J., Massachusetts Institute of Technology, US

As part of an effort to evaluate water-based nanofluids for nuclear applications, preparation and characterization has been performed for nanofluids being considered for MIT’s nanofluid heat transfer experiments. Three methods of generating these nanofluids are [...]

Characterization and Synthesis of Platinum Nanoparticles for the Electrochemical Oxygen Reduction Reaction

Elizondo-Villarreal N., Rodríguez Ramírez F., Gochi-Ponce Y., Alonso Núñez G., José Yacamán M., University of Texas, Austin, US

Metallic nanoparticles are of great interest because of the modification of properties observed due to size effects, modifying the catalytic, electronic, and optical properties of the monometallic nanoparticles.The polyol method has been reported to produce [...]

Measuring Nanoparticle Size Distributions in Real-Time: Key Factors for Accuracy

Erickson K., Singh M., Osmondson B., TSI Incorporated, US

The benefits of sizing aerosolized submicrometer particles using an electrical mobility sizing technique have been well documented. This type of analytical tool has been found to be able to measure particle diameter with an uncertainty [...]

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 [...]

Understanding and utilizing molecular constraints in nanoscale material designs

Sills S., Overney R.M., Micron Technology, Inc., US

Challenges regarding nanoscale material designs often arise from the collision of two sets of critical length-scales; namely, device dimensions approach the length scale of molecular-level processes. On one hand, these finite size constraints cannot be [...]

Characterization of An Integrated 3-Axis CMOS-MEMS Accelerometer

Qu H., Fang D., Xie H., Oakland University, US

This paper reports an integrated 3-axis CMOS-MEMS accelerometer with single proof mass. Sensor design, fabrication process are introduced and detailed characterization of this small-sized accelerometer is addressed. Compared to the previously reported 3-axis accelerometers, most [...]

Structure Characterization of Nanocomposites by Synchrotron X-ray Rays

Hsiao B.S., Stony Brook University, US

In this talk, we will demonstrate that simultaneous small-angle X-ray scattering (SAXS) and wide-angle X-ray diffraction (WAXD) techniques can contribute significantly to the structural analysis on several length scales in nanocomposites containing a soft matter [...]
