We fabricated a 302 mm diameter low-pass filter made of alumina that has an anti-reflection coating (ARC) with laser-ablated sub-wavelength structures (SWS). The been integrated into and is operating the MUSTANG2 instrument, which coupled to Green Bank Telescope. average transmittance in band between 75 105 GHz 98%.

The collaboration between the Solar Energy Research Institute of Singapore (SERIS), Trina Solar and ANU is progressing well, and ANU has already developed all-back-contacted (ABC) silicon wafer cells with best one-sun efficiencies of 21.2% and 22.1% on FZ material, when measured with the aperture areas of 16 cm (includes busbars) and 13 cm (excludes busbars) respectively. This paper presents th...

Radar absorbing materials, i.e. magnetite (Fe3O4) coated carbon fibers (MCCFs) were fabricated by electro-deposition technique. Black-colored single spinel phase Fe3O4 nanoparticles was easily synthesized by hydrothermal method using reduction of a Fe (III) - Triethanolamine complex in an aqueous alkaline solution at 60-80 ◦C. Uniform and compact Fe3O4 films were fabricated on nitric acid treat...

Light reflecting from instrument panel and center console automobile displays is distracting to drivers and necessitates overhanging dashboard designs that take up valuable interior space. A recent trend toward displaying increasing amounts of information with navigation and communication systems, has compounded the significance of light reflection. The conventional anti-reflection (AR) techniq...

An optimized graded-refractive-index (GRIN) antireflection (AR) coating with broadband and omnidirectional characteristics--as desired for solar cell applications--designed by a genetic algorithm is presented. The optimized three-layer GRIN AR coating consists of a dense TiO2 and two nanoporous SiO2 layers fabricated using oblique-angle deposition. The normal incidence reflectance of the three-...

methoxy poly(ethylene glycol) (mpeg) with molecular mass of 5 kda activated with succinimidyl carbonate and cyanuric chloride, separately was covalently attached to human red blood cells (rbcs). inhibition of agglutination by blood-type specific antisera (anti-d) was employed to evaluate the effect of the polymer coating. the remaining single cells after incubation with anti-d sera were counted...

We have developed and tested an antireflection (AR) coating method for silicon lenses used at cryogenic temperatures and millimeter wavelengths. Our particular application is a measurement of the cosmic microwave background. The coating consists of machined pieces of Cirlex glued to the silicon. The measured reflection from an AR-coated flat piece is less than 1.5% at the design wavelength. The...

In previous work, flow visualization was used to understand how polymer processing additives (PPA) eliminate sharkskin in linear low-density polyethylene (LLDPE). The PPA migrates to and coats the die wall, induces slippage, and eliminates sharkskin. In this work, the interface between the PPA and LLDPE was further characterized using reflection light microscopy, scanning electron microscopy, e...
