Self-Healing Wire-Streaming Processors on 2-D Semiconductor Nanowire Fabrics

Wang T., Bennaser M., Guo Y., Moritz C.A., University of Massachusetts Amherst, US

One of the most promising underlying nanodevice technologies today for nanoscale integrated circuits are semiconductor nanowires (NWs) and arrays of crossed NWs. Researchers have already built FETs and diodes out of NWs. There has also [...]

The Pulsation Reactor Process – Large Scale Production of Nano-Sized Metal Oxide Powders in a Single Step

Fischer G., Leidolph L., Weitz U., IBU-tec, DE

A pulsed thermal reactor process was developed to produce nano particles on an industrial scale. Different precursors were applied to obtain the desired product properties. The applied techniques (pulsation reactor) are explained and different applications [...]

Solid-State, On-demand Gas Generators as “Pneumatic Batteries” for Micro-Electronic Actuators and Fluid Delivery

Sawka W.N., Digital Solid State Propulsion LLC, US

Newly developed electrically controlled extinguishable solid propellants (ESCSP) are capable of multiple ignitions, extinguishments and throttle/burn-rate control by the application of continuous electrical power. Both burn rate and mass of ECESP combusted is directly proportional [...]

Multiple Wafer Bonding Offers Increased Throughput of High Brightness LEDs

Pascual D.N., SUSS MicroTec, US

We have developed a new wafer-bonding process and equipment for significantly increasing the throughput of high-brightness light emitting diodes and other devices that could benefit from group semiconductor wafer bonding. I will present this solution [...]

Enlarge the distance of water molecules to incise microorganism cell-the development and application of nano-grade microorganism cell crushing machine

Hongwen Y., Suge G., Hebei University of Science and Technology, CN

We have developed a prototype nano-grade crushing machine that leads to improved yield. The machine utilizes ultrasound in connection with pressure as high as 3400 kg/cm2 to achieve final product with nanometer scale. We have [...]

Experimental Study of Micro-feeding of Fine Powders by a Vibrating Capillary Tube

Shi J., Mahinfalah M., Jang B., North Dakota State University, US

Micro-feeding of fine copper powders was experimentally studied by using a vibrating capillary tube. Three glass capillaries with different inside diameters were used in the experiment and the powder flow rate under different frequencies was [...]

Programmable Three-Dimensional Microfluidic Fabrication by Direct-Write Assembly

Ghafar-Zadeh E., Therriault D., Sawan M., École Polytechnique de Montréal, CA

There are increasing needs for 3D microfluidic components such as microchannels, micromixers or micropumps for Laboratory-on-chip systems. To date, several efficient, but expensive and complex techniques such as Liga and micro-stereo-lithography [1] have been developed [...]

Field Enhancement and Work Function Difference of IrO2 Nano-Emitter Arrays using EFM and SKPM Spectroscopy

Chiang D.C.-S., Lei P.Z.-F., Barrowcliff R., Zhang F., Washington State University and Sharp Corporation, US

We have measured two important physical properties related to field emission (surface potential and electric force gradient) of IrO2 nanorod emitter arrays using spectroscopy methods of electric force microscope (EFM) and scanning Kelvin probe microscope [...]

Comparison of Roughness Measurements Between a Contact Stylus Instrument and an Optical Measurement Device Based on a Color Focus Sensor

Danzl R., Helmli F., Scherer S., Alicona Imaging GmbH, AT

The determination of the roughness of technical surfaces plays an important role in scientific and industrial applications. Traditionally, the ISO conform determination of the roughness of a technical surface has been calculated using contact stylus [...]

Local diffuse light scattering and surface inspection

Caumont M., Bacsa W.S., University Paul Sabatier, FR

Overlap of the incident and scattered field from local surface non-uniformities lead to lateral standing waves which can be mapped using a scanning optical probe in collection mode. The lateral standing waves form diffraction fringes [...]
