Synthesis of copper nanowires via a liquid phase reduction process

ABSTRACT Copper nanowires (Cu NWs) were successfully synthesized via a method of liquid phase reduction by using hydrazine hydrate as reducing agent, ethylenediamine (EDA) as structure-directing agent. The impact of various factors on Cu NWs was analyzed by orthogonal experiment. Cu NWs were characterized by SEM, XRD, and TEM techniques. The results show that: the Cu NWs were free of oxidation, and were highly oriented along the (111) direction. The sequence of factors which impact the length and diameter of Cu NWs is: hydrazine hydrate - NaOH - EDA - reaction temperature. Considering all the factors, to synthesize Cu NWs, the optimal conditions are as follows: 4mL EDA, 50mL NaOH, 10 mL1% hydrazine hydrate, 10 mL 10% hydrazine hydrate, 80°C.

The mechanism study of dust removal with transparent interdigitated electrodes

Abstract Due to the impact of dust on the solar panels cannot be ignored, dust removal technique with electric curtain received extensive attention and research for its own advantages. The mechanism of dust removal with electrical curtain was proposed based on the structure of electric curtain, the force of the dust in the standing waves of electric curtain, the distribution of electric field intensity in the electrode overhead, the physical model calculations of the electrode electric field and the analysis of electrodes breakdown voltage. The work has great significance to the development of dust removal with electric curtain technology.
