Gas transport in nanoscale channels that have perfectly flat walls has been found to be frictionless, challenging the classical theory of gas flow. The findings might enable new devices for gas separation and flow control.Gas transport in nanoscale channels that have perfectly flat walls has been found to be frictionless, challenging the classical theory of gas flow.

在完美平壁纳米通道中观察到的无摩擦气流

已经发现具有完美平坦壁的纳米级通道中的气体传输是无摩擦的，挑战了经典的气流理论。这些发现可能为气体分离和流量控制提供新的设备。已发现具有完美平坦壁的纳米级通道中的气体传输是无摩擦的，挑战了经典的气流理论。这些发现可能会启用用于气体分离和流量控制的新设备。
