石墨烯可以产生高能量超短脉冲 OPTICS EXPRESS,Vol. 17, P17630. http://www3.ntu.edu.sg/home2006/zhan0174/OE_graphene.pdf Abstract: We report on large energy pulse generation in an erbium-doped fiber laser passively mode-locked with atomic layer graphene. Stable mode locked pulses with sing ...
Nerve signals may be shock wave riders: Wired has a good break down of theory that says that nerve cells don't work on electricity as we assume, but instead transmit signals using pressure waves, and crucially, this might explain how anaesthetics work. The idea that nerve cells send the ...
Nonlinearity in the heart Nonlinear wave dynamics can help to explain what happens to the heart during an irregularity of the heartbeat known as a cardiac arrhythmia. Computer models of the process are helping to improve methods for treating this potentially lethal medical condition. Your ...
Solitons underpin new laser Ackemann and colleagues Physicists in the UK and Germany have harnessed the curious properties of soliton waves to create a new type of semiconductor laser that can be switched on and off using light pulses. The team believe that this cavity solit ...
