Abstract:
Metallic nanoscale particles attract a growing interest in several fields, thanks to their unique bonding characteristics; applications are appearing in the literature in the fields of, for example, sensor coatings and biochemical compound detection. However, the controlled fabrication of such nanopowders is often cumbersome, especially because their characterization is normally slow, involving procedures such as electron microscopy. On the other hand, microwave sensors based on near-field effects on materials are being developed with high sensitivity and show promising characteristics. In this paper, the authors show how a microwave sensor based on a Square Spiral Resonator can be used to characterize paraffin dispersions of nanoparticles conveniently and cost-effectively.
摘要:
金属纳米颗粒在几个领域吸引了越来越多的兴趣,由于其独特的键合特性;在文献中出现了应用,例如,传感器涂层和生化化合物检测。然而,这种纳米粉末的受控制造通常很麻烦,特别是因为它们的表征通常很慢,涉及电子显微镜等程序。另一方面,基于材料近场效应的微波传感器正在开发中,具有高灵敏度和有前途的特性。在本文中,作者展示了如何基于方形螺旋谐振器的微波传感器可用于方便地和经济地表征纳米颗粒的石蜡分散体。
