答:微乳液是指由表面活性剂、助表面活性剂(如醇类)、油类(碳氢化合物等)组成的透明的、各向同性的热力学稳定体系。微乳液法制备纳米粒子有如下特点:1)由于成核生长是在水核中进行,水核的大小决定了微粒的大小。因此通过控制溶剂剂量、表面活性剂用量及适当的反应条件,可以较容易的获得粒径均匀的纳米微粒,而且尺寸...

Gold and silver are relatively inert in bulk amounts. On the nanoscale, however, they demonstrate unique catalytic properties. For example, silver nanoparticles are an effective antibiotic. Nanoparticles of gold have proven to be efficient at removing volatile organic compounds from the atmosphere, eve...

Nanoparticles are materials that are confined to the nanoscale in all three dimensions. Engineered nanoparticles play an important role in nanotechnology. The specific properties of nanoparticles is defined by particle size, chemical composition, crystal
What Are Gold Nanoparticles? The term “nanoparticles” refers to a material in which at least one dimension (in a 3D space) ranges between 1 and 100 nanometers in size. This is equivalent to the size of 10-1000 atoms closely packed together. ...
