A process for manufacturing high aspect ratio silver nanowires is provided, wherein the recovered silver nanowires exhibit an average diameter of 25 to 80 nm and an average length of 10 to 100 \u03bcm; and, wherein the total glycol concentration is <0. A net is connected to the winch and passes over a roller mounted at the outer ends of the hydraulic arms which are vertically and horizontally movable to position the net over the body of water. A currentvoltage converting circuit 132 converts a synthesized current I0 obtained by synthesizing the first IC current I1 and second IC current I2 to a corresponding IC voltage Vic. The stop portion is formed at an end of the swinging member and received in the fastener drive track. The azo liquid-crystal compound is capable of orientation with a high degree of orientation order.
