Understanding Spark Ablation Technology
Spark ablation technology is a method developed for generating nanoparticles by applying high energy to a thin metal wire until it erupts, creating both larger and nano-sized fragments. This innovation emerged in the 1980s when researchers discovered that high-energy sparks could efficiently produce nanoparticles without the contamination associated with chemical synthesis methods. This technology offers a significant advantage in producing pure and high-quality nanoparticles since it avoids the complexities and impurities introduced by liquid environments. As such, spark ablation stands out for its ability to produce nanoparticles quickly and with precise control over size and elemental composition.
