An AlGaN/GaN high electron mobility transistor (HEMT) with tungsten nitride (WNx) Schottky gate fabricated on a sapphire substrate is presented. Gate forward current stress was chosen to evaluate the stability of the Schottky gate. After stress, this WNx HEMT remains stable, while the conventional Ni/Au HEMT shows performance degradation and failure. The maximum output power density from this device is 5 W/mm at 2 GHz. A combination of these findings indicates the robust performance of this WNx material and its potential as a Schottky gate for AlGaN/GaN HEMTs.

A fiber grating sensor including an elastic circular plate and one or two FBG'ss attached to the bottom surface of the elastic circular plate. Two ends of the FBG are connected to an optic fiber for signal transmission. The fiber grating sensor readouts are independent of temperature variation. The fiber grating sensor mechanism according to the present invention may be applied in a variety of sensors such as gauge pressure transducer, differential pressure transducer, load cell and displacement transducer with a distributive design, and for various purposes.

This paper describes the photomodification of borosilicate glass substrates assembled with 40 nm diameter gold nanoparticles (Au NPs) with surface coverages ranging from 17 to 23% on excitation of the localized surface plasmon band of the NPs with a 532 nm nanosecond pulsed-laser beam. The laser irradiation allowed the splitting and fusion of NPs on the substrate surface and, at the same time, the formation of craters of less than 10 nm diameter at various places following one laser shot with a relatively high intensity of 460 or 370 mJ.cm(-2).pulse(-1) but well below the breakdown threshold of 25-40 J.cm(-2).pulse(-1). The formation of the craters was more and more distinctly observed by continuous irradiations. The number density, average diameter, and the surface coverage of the craters were not linearly dependent on the laser shot number but exhibited the saturation behavior due to the consumption of Au NPs. The threshold laser energy for the crater formation was dependent on the accumulated number of laser shots: a greater number of laser shots were necessary to form craters as the laser fluence decreases. Most interestingly, the laser-irradiated areas of the substrate exhibited a greater susceptibility to the wet chemical etching with aqueous hydrogen fluoride. The mechanism of the laser modification and a possible application to nanofabrication on glass surfaces by utilizing Au NPs were discussed on the basis of the scanning electron microscopy (SEM) observation as well as the extinction and light scattering spectroscopic measurements.
SYSTEM AND METHOD THEREOF FOR DYNAMICALLY ADJUSTING SLEEP/AWAKE INTERVALS OF WIRELESS NETWORK DEVICE

A system and a method thereof for dynamically adjusting sleep/awake intervals of a wireless network device are provided. The system has at least one base station (BS) and at least one wireless network device. The system performs the method to dynamically adjust the sleep/awake intervals by properly delaying and combining delivery of data such that the wireless network device is turned into a sleep mode after finishing data delivery within an adjusted period. Thereby, the number of awake frames of a mobile subscriber station (MSS) can be reduced without sacrificing the quality of service (QoS).

We demonstrated a micro-chemoresistive gas sensing device using mesoporous carbon as the sensitive film and immobilized by dielectrophoresis (DEP) process. The mesoporous materials were characterized by X-ray diffraction (XRD) patterns, N(2) adsorption-desorption isotherms, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). N(2) adsorption-desorption isotherms shows the specific surface area of 1200 m(2)/g, total pore volume is 1.2 cm(3)/g of the mesoporous carbon, and the pore size distribution of mesoporous carbon yields an average pore size of 3 nm. SEM images show a rod-like morphology and TEM images show a highly ordered pore channel with linear arrays. CO gas sensor properties were measured and the resulting sensitivities were 5.7, 6.8, 8.8, 11.6, and 37.6% for concentrations of 30, 45, 60, 75, and 90 ppm. respectively. Additionally, this sensor also exhibited high sensitivity and fast response times for CO gas. Crown Copyright (C) 2009 Published by Elsevier B.V. All rights reserved.

在高樓聳立的城市中行快步行走，有時候我們必須換上一張偽裝的臉，用微笑表達謙和有禮；還有更多的時候，大哭、大笑、大吵、或大鬧都是不被允許的。西裝外套裡挾帶了風的自由和海的寬闊，眼前的蔡政良，言談間充滿豐富的表情和止不住的笑聲。別人稱呼他阿良或是工頭，然而更多人叫他Futuru──這是阿美族的名字，意思是「真正的男人」。

擬人，不完全等同於文學修辭上的擬人法，而是源自於日本動漫界，對於物品、國家、交通工具等，依照彼此之間不同的特性建立出特定的角色的創作方式。近年來「擬人化」熱潮持續增溫，一本《超萌！化學元素週期表：118動漫少女幫你奠定化學基礎》於今年11月30日出版，讓原本屬於次文化範疇中的創作行為，觸及了主流文化的邊緣。
