Artificially creating electrochemical sites by the induced copper dissolution with STM tips

[中文文摘]在电极电位稍负于其Nernst电位时 ,较正的探针电位可以诱导铜表面的局域刻蚀 ;同时 ,利用这一诱导刻蚀可以方便地人工构筑电极表面电化学活性位或特定的纳米结构 ,如现场构筑坑 (pit)、螺旋岛 (spiralisland)和岛 (island)等电化学活性位 ;并现场研究它们相关的 (电 )化学反应。[英文文摘]STM tip was found to be able to induce local dissolution of copper by applying a rather positive tip potential while the electrode is controlled at a cathodic potential of bulk copper deposition in dilute Cu 2+ solution. Furthermore, we present the possible artificially creating of electrochemical sites by using induced copper dissolution with STM tip. Spiral islands, normal islands and pits were easily created. The crystal growth on the artificial islands during the electrodeposition was followed.国家自然科学基金; 教育部高等学校博士点基金资助项目 (20173046)

Study on Analysis of the Non - saponifiable Matter Constitution of Bees - wax Produced in Fujian

作者采集了福建省八地区的蜂蜡样品,对其组成进行系统的分析研究——皂化后分离出的非皂化部分(高级脂肪醇C_(22-32)),通过红外光谱和质谱以及气相色谱分析研究其组成结果,可以确定高级脂肪醇C_(22-32)的分布及其结果,利于以其为原料生产正-三十烷醇的厂家对不同地区蜂蜡的选取。The constitution of bees-wax samples were separated and analysed by IR, MR and GC. The corresponding results show that the bees - wax produced in different area has different amount of higher alcohos

FPGA Implementation of Frequency Hopping Algorithm for Bluetooth

跳频是蓝牙使用的抑制干扰的关键技术。在简要介绍扩频技术的基础上,对蓝牙系统基带部分的跳频算法进行了详细分析,并用VHDL完成该算法的硬件描述。在Xilinx ISE开发环境下完成综合及后仿真,通过蓝牙标准提供的样本数据的测试验证,最后下载到Xilinx Virtex-Ⅱ器件上实现。该设计的实现可应用于蓝牙基带芯片的研发。Frequency hopping is the key technology used to suppress interference in Bluetooth system. Based on the simple introduction of spread spectrum technique, the analyzing on the frequency hopping of baseband in Bluetooth system and the implementation of this algorithm with VHDL are given . The synthesis and post simulation have also been done under the Xilinx ISE tools. Its correctness has been validated through the sample data which were given by the Bluetooth specification. Finally it was implemented in Xilinx Virtex-II successfully. This design can be used in the development of Bluetooth ASIC
