3·Organic lasers are not as powerful as traditional lasers made with gallium or indium compounds, but they can be easily printed or deposited directly on any type of surface.

这种激光器不是由传统的镓和铟制造的，也不具有传统激光器的威力，但是是用这种材料制造的激光器很容易直接放置到任何物体的表面。

4·Production of such nanoscale wires need to be a kind of organic molecules and gallium salt mixture placed in a super-clean silver foil.

制作这种纳米级的金属线需要将一种有机分子和镓盐的混合物置于一个超级干净的银薄片上。
