Analysis of Gate-Length Dependence of Lags and Current Collapse in Field-Plate AlGaN/GaN HEMTs

Chiba T., Saito Y., Tsurumaki R., Horio K., Shibaura Institute of Technology, JP

We make 2-D transient simulations of field-plate AlGaN/GaN HEMTs with a semi-insulating buffer layer, where a deep acceptor above the midgap is considered. We particularly study how the gate lag, drain lag and current collapse [...]

Molecular Dynamics Simulation Study on Nanoelectromechanical Oscillator based on Graphene Nanoflake

Kwon O-K., Kang J-W, Semyung University, KR

Recently graphene has also been highlighted as an ideal lubricant for microelectromechanical systems (MEMSs) and nanoelectromechanical systems (NEMSs), where ‘traditional’ lubricants no longer function normally. Atomic-scale graphene can be fabricated using micro- mechanical chop crack, [...]

Vibration Assisted Injection Molding for PLA with Enhanced Mechanical Properties and Reduced Cycle Time

Duhduh A., Kundu A., Coulter J., Lehigh University, US

Vibration assisted molding (VAIM) is a process in which vibrational movement is introduced to the injection screw during the injection stage of molding processes. This research was focused on the effect of processing parameters on [...]

Multilayer Low Tg Inorganic Glass/Polymer Barrier Films

Vennerberg D., Bemis Company, Inc., US

Conventional high barrier films are produced by coating or laminating inorganic materials to polymeric substrates. While successful at lowering the permeability of the films, several unit operations are required to introduce multiple inorganic barrier layers. [...]

Vitamins C and B1: Amorphization, Crystallization, and Vitamin Degradation

Mauer L.J., Ismail Y., Arioglu-Tuncil S., Voelker A.L., Purdue University, US

Crystalline ingredient forms of water soluble essential vitamins C and B1 may dissolve or melt during food production, and then re-solidify in crystalline or amorphous forms. This study compared the phase transformations, amorphization, and chemical [...]

Yeast Cell Wall Particle Encapsulation of Pro-Terpene Payloads

Soto E., Rus F., Ostroff G., University of Massachusetts Medical School, US

Terpenes are naturally occurring compounds produced by plants that have long been recognized for their insecticidal, antimicrobial, and antioxidant properties. However, applications of terpenes have been limited by their volatility and poor water solubility resulting [...]

An ultrasensitive and culture-free detection platform for microorganisms and protein biomarkers

Yau S.-T., Rapidect, Inc., US

We have developed an electrochemical immunoassay platform, which detects a range of disease-related targets including bacteria, viruses, fungi and protein biomarkers. The platform features a voltage-controlled signal amplification, which leads to ultrasensitive detection. The analytical [...]

Catalytic Nanoparticles to Enhance the Sensitivity of Lateral Flow Immunoassays

Kidwell D.A., Wei E., Lanese J.N., Mulvaney S., Naval Research Laboratory, US

Lateral-flow immunoassays (LFIAs) are a widely used point- of-care technology. They are most familiar as home-pregnancy tests, but are also employed for testing for a wide variety of diseases, biomarkers, and even small molecules. By [...]

Nanobiomimetic Structured Organo-Metal Devices Direct Rapid Real-time Monitor Atto Molarities of ATP in Biological Specimens

Chen E.T., Thornton J.T., Duh S-H, Kissinger P.T., Advanced Biomimetic Sensors, Inc., US

Real-time monitoring of ATP in biological specimens is a convenient means to monitor the hygiene in healthcare units and for medical devices. Rapid and precise monitoring of ATP has been in strong demand. We report [...]

An electrostimulation cell device with patterned TiO2: Nb thin films as bio-electrodes

Jobin M., Pellodi C., Sandu C., Benvenutti G., Sandoz A., Stoppini L., hepia / HES-SO University of Applied Sciences of Western Switzerland, CH

We present a cellular test device based on Nb:TiO2 (niobium dooped titania) transparent conductive oxide (TCO) as bio-electrodes. The device is intended to easily provide electrical stimuli to a given cell tissue and to monitor [...]
