The nucleation and growth of NPs in the gas phase using atmospheric-pressure plasma systems is an important approach to synthesizing novel dimensionally-controlled materials. Here, we investigated the effect of the NPs on a typical type of continuous-flow, substrate-free plasma at atmospheric pressure to understand their potential contribution to electron density changes. A tandem plasma system was set up consisting of one plasma reactor that produced carbonaceous NPs from mixtures of argon and hexane, and another identical plasma reactor where the as-grown particles were injected and non-intrusive electrical and optical measurements were performed. The electron densities obtained from conductivity measurements and a plasma fluid model were found to decrease in the presence of NPs. However, control experiments revealed that the main source of the electron depletion was residual vapor or reaction byproducts in the form of molecular species or nanoclusters and not the particles th...

了解大气压下尘土等离子体中电子的消耗

使用大气压等离子体系统在气相中NP的成核和生长是合成新型尺寸控制材料的重要方法。在这里，我们研究了NPs在大气压下对典型类型的连续流动，无底物等离子体的影响，以了解它们对电子密度变化的潜在影响。建立了串联等离子体系统，该系统由一个等离子体反应器和另一个相同的等离子体反应器组成，该等离子体反应器从氩气和己烷的混合物中生成碳质NP，并在其中注入生长中的颗粒，并进行非侵入式电和光学测量。发现从电导率测量和等离子流体模型获得的电子密度在NP的存在下降低。然而，
