Fig. 8From: Can We Optimize Arc Discharge and Laser Ablation for Well-Controlled Carbon Nanotube Synthesis?Schematic representation of experimental setup for a solar evaporation system. Target and pipe are heated by the incident solar radiation from the Sun. The hot channel between the target and pipe acts as local furnace, avoiding the need of external furnace.
