黄金万物难驻留

Nature’s first greer is gold,Her hardest hue to hold.Her early leaf’s a flower;But only so an hour.The leaf subsides to leaf,So Eden sank to grief,So dawn goes down to day.Nothing gold can stay.

解题之妙在于方法

物理学是一门具有方法论的科学,通过学习物理领略、感悟其中的方法比学习具体的知识更重要.在解决具体问题中所出现的障碍,往往不是知识本身,而是思路、方法不对头造成的.下面仅举一例予以说明.现有电源、电铃、小灯泡各一个,开关三个(S1、S2、S3),导线若干,请你设计电路。设计要求:(1)只有S1闭合时,灯泡亮,电铃不响;(2)只有S2闭合时,电铃响,灯泡不亮;(3)只有S3闭合时,电铃响,灯泡也亮;(4)三个开关S1、S2、S3不能同时闭合.分析1:首先考虑到串联和并联两种最基本的电路连接方式,即设想灯泡和电铃是串联或并联的,画出基本电路后再设法接入…

Gold Nanoparticles of Multiple Shapes Synthesized in L-Tryptophan Aqueous Solution

In this paper, we describe a simple and efficient synthesis of gold nanoparticles(GNPs) of various shapes(spherical, rod-like, hexagonal, truncated triangular, and triangular) using Au(Ⅲ) reduction in aqueous solutions by L-tryptophan. We evaluated the influences of reaction temperature, foreign metal ions Ag(Ⅰ), and surfactants of nonionic(polyethylene glycol, PEG), anionic(sodium dodecyl sulfate, SDS), and cationic(cetyltrimethyl ammonium bromide, CTAB) on GNPs synthesis. We characterized the resultant GNPs using UV–visible adsorption spectroscopy, transmission electron microscopy/high-resolution transmission electron microscopy, scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, selected-area electron diffraction, and Fourier-transform infrared spectroscopy. We fabricated the variously sized GNPs by controlling the rate of the reduction of gold ions in aqueous solution by varying the reaction temperature: the higher the temperature, the smaller the gold nanospheres. We found the existence of Ag(Ⅰ) to reinforce the reduction of Au(Ⅲ) and to correspond with the appearance of some amorphous bimetallic Au/Ag nanoparticles. Additionally, we found the presence of surfactants to greatly influence the shape of the formed GNPs, especially the presence of CTAB, which results in the anisotropic growth of gold nanocrystals into hexagonal, truncated triangular, and triangular nanoplates. In addition, with the increase in CTAB concentration, we found the amount of gold nanoplates to first increase and then decrease. Finally, we performed preliminary explorations of the reduction process and morphological evolution to propose possible corresponding reduction and morphological evolution pathways.

多媒体课件中色彩媒体的研究

颜色是物体的一个物理属性，物体发射或反射不同波长的光波应构成该物体的颜色。颜色的特性可以用三个参数来描述，即色调（hue)、明度(brigheness)和彩度(saturation)。各种颜色都能引起不同的联想，依据在心理上产生不同的冷暖感觉，可分成冷色、暖色两大系统。冷色如青、蓝、紫等色，暖色如红、橙、黄等色，绿色偏中性。
