The arcuate fasciculus is the neural tract connecting the two major speech centers（Broca’s and Wernicke’s areas）and plays a critical role in language function（Catani and Mesulam,2008）.Injury of this tract can lead to several types of language impairment,including conduction aphasia,Broca’s aphasia,anomic aphasia,and apraxia of speech（Anderson et al.,1999;Bartha and Benke,2003;Catani and Mesulam,2008;Bernal and Ardila,2009;Kim et al.,2011）.

Hidradenocarcinoma originates in the eccrine glands located in sun-exposed areas and accounts for approximately 6% of malignant eccrine tumors and 〈0.001% of all skin cancers.[1,2] Hidradenocarcinoma usually presents as a solitary,firm,asymptomatic intradermal nodule measuring 1-5 cm,covered by intact or occasionally ulcerated purple-,pink-,or blue-colored lesions.[1] While hidradenocarcinoma typically grows slowly over many years,it may suddenly undergo a rapid increase in *** differential diagnosis of hidradenocarcinoma is very challenging because the appearance of the lesion is benign and similar to that of other skin *** this report,we present the case of a patient with hidradenocarcinoma who was treated with wide excision and full-thickness skin grafting.

Frontiers of Optoelectronics 2012年第2期5卷 127-132页

作者： Sei-min KIM Seon-Ho jang Ja-Soon jang Department of Electronic Engineering LED-IT Fusion Technology Research Center (LIFTRC) Yeungnam University Gyeongbuk 712 749 Korea

This work demonstrates high-performance and current crowding-free InGaN/GaN light-emitting diodes （LEDs） using an electrically-reverse-connected Schottky diode （SD） and an Mg-delta （δ） doped layer. Possible mechanism of carrier transport at the interface between transparent conducting electrode （TCE） and p-GaN with the δ-doped layer is also investigated. Results show that the LED with the SD and Mg delta （δ）-doping layer yields lower series resistance, higher output power, and lower reverse leakage current compared to normal LEDs. In addition, unlike the normal LED, there is no occurrence for the current crowding effect in the proposed LED even at high current density of 380mA/cm2. These remarkable behaviours clearly indicate that the use of the SD and δ- doping in the p-GaN region is very promising to achieve high-brightness and excellent-reliability GaN-based LEDs.

Al合金表层的缺陷常常会导致腐蚀发生。因此,采取保护措施以提高铝合金的抗腐蚀性能是非常重要的。从电化学的角度出发,对固溶、淬火和时效处理工艺进行优化,以提高铝合金的强度。在不同电位(-05～-1.8V)下进行慢应变速率拉伸实验。结果表明:与未经强化处理的铝合金相比,经固溶强化热处理的铝合金表现出高的最大拉伸强度、伸长率和断裂时间。由于经固溶强化处理的铝合金的伸长率增加,其拉伸断裂时间也随之增加。在电位-1.3～-0.7V范围内,样品具有优异的力学性能,因此,该电位范围被认为是该合金的腐蚀保护范围。

Energy and environmental issues presently attract a great deal of scientific attention. Recently, two-dimensional MXenes and MXene-based nanomaterials have attracted increasing interest because of their unique properties (e.g., remarkable safety, a very large interlayer spacing, environmental flexibility, a large surface area, and thermal conductivity). In 2011, multilayered MXenes (Ti3C2Tx, a new family of two-dimensional (2D) materials) produced by etching an A layer from a MAX phase of Ti3AlC2, were first described by researchers at Drexel University. The term “MXene” was coined to distinguish this new family of 2D materials from graphene, and applies to both the original MAX phases and MXenes fabricated from them. We present a comprehensive review of recent studies on energy and environmental applications of MXene and MXene-based nanomaterials, including energy conversion and storage, adsorption, membrane, photocatalysis, and antimicrobial. Future research needs are discussed briefly with current challenges that must be overcome before we completely understand the extraordinary properties of MXene and MXene-based nanomaterials.
