Composite material and process for producing the same

Abstract: Provided herein is a composite material which comprises a polyamide-containing resin, a layered silicate dispersed therein, and a substance such as polyamine which controls the crystalline structure or molecular structure of the resin. The composite material has improved mechanical strength and toughness and high clarity or transparency.

Full Four-Channel 6.3-Gb/s 60-GHz CMOS Transceiver With Low-Power Analog and Digital Baseband Circuitry

Abstract: This paper presents a 60-GHz direct-conversion RF front-end and baseband transceiver including analog and digital circuitry for PHY functions. The 65-nm CMOS front-end consumes 319 and 223 mW in transmitting and receiving mode, respectively. It is capable of more than 7-Gb/s 16QAM wireless communication for every channel of the 60-GHz standards, which can be extended up to 10 Gb/s. The 40-nm CMOS baseband including analog, digital, and I/O consumes 196 and 427 mW for 16QAM in transmitting and receiving modes, respectively. In the analog baseband, a 5-b 2304-MS/s ADC consumes 12 mW, and a 6-b 3456-MS/s DAC consumes 11 mW. In the digital baseband integrating all PHY functions, a (1440, 1344) LDPC decoder consumes 74 mW with the low energy efficiency of 11.8 pJ/b. The entire system including both RF and BB using a 6-dBi antenna built in the organic package can transmit 3.1 Gb/s over 1.8 m in QPSK and 6.3 Gb/s over 0.05 m in 16QAM.

Tellurite microstructure fibers with small hexagonal core for supercontinuum generation.

Abstract: Tellurite glass microstructure fibers with a 1 µm hexagonal core were fabricated successfully by accurately controlling the temperature field in the fiber-drawing process The diameter ratio of holey region to core (DRHC) for the fiber can be adjusted freely in the range of 1–20 by pumping a positive pressure into the holes when drawing fiber, which provides much freedom in engineering the chromatic dispersion With the increase of DRHC from 35 to 20, the zero dispersion wavelengths were shifted several hundred nanometers, the cutoff wavelength due to confinement loss was increased from 1600 nm to 3800 nm, and the nonlinear coefficient γ was increased from 39 to 57 W-1/m Efficient visible emissions due to third harmonic generation were found for fibers with a DRHC of 10 and 20 under the 1557 nm pump of a femtosecond fiber laser One octave flattened supercontinuum spectrum was generated from fibers with a DRHC of 35, 10 and 20 by the 1064 nm pump of a picosecond fiber laser To the best of our knowledge, we have for the first time fabricated a hexagonal core fiber by soft glass with such a small core size, and have demonstrated a large influence of the holey region on the dispersion, nonlinear coefficient and supercontinuum generation for such fiber

Method of and apparatus for refroming fuel and fuel cell system with fuel-reforming apparatus incorporated therein

Abstract: Methanol supplied as a raw fuel is mixed with water, vaporized in an evaporator 24, and supplied to a reformer 22 as a raw fuel gas. The reformer 22 also receives a supply of the compressed air from an air tank 36. The raw fuel gas is mixed with the compressed air in the reformer 22. An oxidation reaction of methanol supplied as the raw fuel proceeds in the reformer 22 to generate hydrogen and carbon dioxide, while a steam reforming reaction of methanol simultaneously proceeds in the reformer 22 to generate hydrogen and carbon dioxide. The amount of heat required for the endothermic reforming reaction can be supplied by the oxidation reaction of methanol. No external heat source is accordingly required in the reformer 22 to supply the heat required for the reforming reaction.
