We investigate the performance of superconducting nanowire photon detectors fabricated from ultra-thin Nb. A direct comparison is made between these detectors and similar nanowire detectors fabricated from NbN. We find that Nb detectors are significantly more susceptible than NbN to thermal instability (latching) at h…
Prevailing methods of magnetotelluric (MT) data analysis determine the spectra using variations of the Fourier Transform (FT), which is based on the principle of signal stationarity. However, MT data series are non-stationary random signals that do not meet the basic requirements of conventional methods based on the F…
BACKGROUND: Sonodynamic therapy (SDT) is a promising methodology for cancer treatment. Methylene blue (MB) is a phenothiazine dye that is widely used in clinical practice and can be administered intravenously. MATERIALS AND METHODS: The sonodynamic antitumor effect of 1, 10 and 100 microM MB on sarcoma180 (S180) cells…
For ion and neutron spectrometry and imaging applications at a high intensity pulsed laser facility, fast liquid scintillators with very low afterglow are required. Furthermore, neutron imaging with fiber (or liquid-core) capillary arrays calls for scintillation materials with high refractive index. To this end, we ha…
It is well known that a multiband frequency selective surface (FSS) can be obtained by arranging multiple simple apertures in a periodic array. However, this simple combination can not achieve a perfect resonance response in a wide band due to the restriction of the grating lobe frequency determined by the array. A ne…
In this review, we consider the application of solid micro- and nanostructures of various shapes as building blocks for micro-electro-mechanical or nano-electro-mechanical systems (MEMS/NEMS). We provide examples of practical applications of structures created by MEMS/NEMS fabrication. Novel devices are briefly descri…
Due to the enhanced interaction among constituents and the resultant effect of particle size on the elastic modulus, nanocomposites with volume fractions higher than 12% show critical nondilute concentrations. In order to describe nondilute concentrations and the effect of particle size, a multi-inclusion model was ad…
The study of (AgCu)(InGa)Se2absorber layers is of interest in that Ag-chalcopyrites exhibit both wider bandgaps and lower melting points than their Cu counterparts. (AgCu)(InGa)Se2absorber layers were deposited over the composition range 0OC= 890 mV, JSC= 20.5 mA/cm2, fill factor = 71.3%, and ¿ = 13.0%.
Micro- and nano-sized metal, semiconductor, pharmaceutical, and simple or complex ceramic particles have numerous applications in the development of sensors, thermal barrier coatings, catalysts, pigments, drugs, etc. The challenges include controlling the particle size, size distribution, particle crystallinity, morph…
Contrast-induced acute kidney injury (CIAKI) is the most-common form of in-hospital drug-induced acute kidney injury and occurs in 1 to over 50% of patients undergoing intravascular contrast media (CM) administration. Numerous risk factors for CIAKI have been described, the most prominent among them is pre-existing ki…
The normally-off AlGaN/GaN HFETs on Si substrate were fabricated. To realize normally-off characteristic, recess was formed under the gate electrode and NiOx was formed as a gate electrode. As a result, the fabricated AlGaN/GaN HFET with a gate width of 157 mm exhibited a threshold voltage of +0.8 V, a breakdown volta…
Abstract A tunable liquid crystal lenticular lens array is proposed to compose an auto‐stereoscopic 3D display. The focusing can be achieved based on non‐uniform phase retardation across the width of the LC lenticular lens, mimicking the effects of gradient index (GRIN) lens. The viewing distance and zones of this dis…
Abstract This paper will describe the implementation of a 3D film method for achieving full resolution autostereoscopic 3D displays in handheld and portable devices. The three components of this technology ‐ a directional backlight, 3D Film and a 120Hz LCD panel ‐ will be described. Modeling and experimental device pe…
Abstract This paper is part of a project devoted to study the pyrolysis process as an alternative for recycling sheet molding compound (SMC), a thermoset composite of polyester and fiberglass. A standard SMC was pyrolyzed under nitrogen, at 300, 400, 500, 600, and 700°C, for 30 min in a 3.5‐dm3 autoclave. This paper f…
Clearance of product related aggregates in therapeutic proteins is a major focus of purification process development. A typical purification process will have one or two chromatographic steps that remove these product related aggregates to an acceptable level. Both cation exchange and anion exchange chromatography can…
Polycrystalline silicon (pc-Si) thin-films with a grain size in the range of 0.1–100 μm grown on top of inexpensive substrates are economical materials for semiconductor devices such as transistors and solar cells and attract much attention nowadays. For pc-Si, grain size enlargement is thought to be an important para…
With the discovery of reverse gyrase in 1972, from Yellowstone National Park, isolated from Sulfolobus acidocaldarius, it has been speculated as to why reverse gyrase can be found in all hyperthermophiles and just what exactly its role is in hyperthermophilic organisms. Hyperthermophiles have been defined as organisms…
For future power system, a micro power grid system, which is mainly composed of several power modules, such as superconducting (SC) cable, superconducting magnetic energy storage (SMES) system, hydrogen system, fuel cell (FC) system, renewable energy modules, and power converter modules, is expected. In the grid syste…
Films of Ni 1− x Pt x ( x =0, 0.02, 0.04, 0.06, and 0.08) have been prepared on fluorine-doped tin oxide-coated (FTO) glass substrates by a chemical plating method and used as the photocathode for dye-sensitized solar cells (DSCs). The Ni 0.94 Pt 0.06 film consisted of nanoparticles with a size of 4–6 nm and a Pt load…
This paper focuses on analysis of charging of polymeric surfaces by means of impulse corona discharges in air. Internal (space charge densities and electric fields) as well as external (circuit current) characteristics of corona in a point-plane electrode configuration are investigated by means of computer simulations…
