Near-Infrared Laser Actuated Cantilevers with Wavelength-Dependent Response

Lucas T.M., James K.T., Beharic J., Moiseeva E.V., Keynton R.S., O’Toole M.G., Harnett C.K., University of Louisville, US

Development of microscale actuating technologies has been critical for interacting with natural components at the cellular level. Small-scale actuators and switches have potential in areas such as microscale pumping and particle manipulation. Thermal actuation has [...]

Virtual pivot point MEMS rotary comb actuator with externally mounted mirror for optical applications

Amin T.M.F., Huda M.Q., Tulip J., Jäger W., University of Alberta, CA

The design, fabrication, and characterization of a virtual pivot MEMS actuator with externally mounted mirror is presented. The provision for an externally mounted mirror can be useful for many optical applications which require large and [...]

Hermetic room temperature glass welding technology

Lunden H., Kumpulainen T., Määttänen A., Vihinen J., Primoceler Ltd, FI

The aim of this study was to find an alternative method for conventional glass-glass bonding. The goal was to minimize heat affect, shorten process time, and avoid use of additive materials but still obtain excellent [...]

AFM/SNOM Cantilever Probe Serial Fabrication Process with Controlled Tip Nanoaperture

Tsigara A., Belier B., Maillard F., Falgayrettes P., Nativel E., Kribich R., Gall-Borrut P., Universite Paris Sud, FR

In this paper we present the microfabrication steps of sol gel and polymer (SU8) based cantilever probe systems using an alternative batch front face fabrication process. The probes are consisting of cantilevers with pyramidal nanoengineered [...]

Precision Micro-Optical Elements for Manufacturing of Gas Sensors using IR-Absorption

Quenzer H.-J., Janes J., Stenchly V., Schwarzelbach S., Wagner B., Dudde R., Fraunhofer Inst. Silicon Technology, DE

A new process technology has been developed by Fraunhofer Institute Silicon Technology for manufacturing precise optical components from borosilicate glass by eight inch wafer batch processing. Glass forms are produced by a contact-less glass flow [...]

Aerospace Applications for Surface Acoustic Wave Devices

Wilson W., NASA Langley Research Center, US

Surface acoustic wave (SAW) technology can be used to create a variety of different sensors, including strain, chemical, pressure, and temperature. These sensors can be configured to be passive and wireless, which could be useful [...]

First-Order-Reversal-Curve Analysis of Nanoscale Magnetic Materials

Dodrill B.C., Spinu L., Lake Shore Cryotronics, US

Magnetic nanowires, nanodots and nanoparticles are an important class of nanostructured magnetic materials. These structures are ideal candidates for important technological applications in spintronics, high density recording media, microwave electronics, permanent magnets, and for medical [...]

Converting Dimensions: A Facile and High-Yield Route for Getting Sub-100 nm Silicon Nanowires

Lee S-H., Yonsei University, KR

For synthesizing uniform sub-100-nm Si nanowires (NWs), we introduce a metal-assisted chemical etching (MCE)-based facile and high-yield route, employing simple thermal annealing and vacuum deposition processes. Under rapid thermal annealing, an ultrathin Ag film on [...]

A New Biocomposite Electrode Sensor for the Detection of Oxidative Reactions

Assan D., Gao X., Lai J.C.K., Leung S.W., Idaho State University, US

Hemoglobin has a very strong affinity with oxygen and thus is a good catalyst to carry oxygen for many oxidation reactions. Many researchers have explored this property of hemoglobin to develop sensors for the detection [...]

Use of Single Particle Inductively Coupled Plasma Mass Spectrometry to Characterize a New Silver Nanoparticle Reference Material

Murphy K.E., Liu J., Guthrie W.F., Gorham J.M., Bonevich J.E., Allen A.J., Winchester M.R., Hackley V.A., MacCuspie R.I., National Institute of Standards and Technology, US

In this study we use a conventional inductively coupled plasma mass spectrometer operated in single particle mode (spICP-MS) to simultaneously characterize the size distribution and dissolved silver fraction of a new candidate silver nanoparticle reference [...]
