HIGHLIGHTS
- who: Friction et al. from the Jiangsu Key Laboratory for Design and Manufacture of Micro-Nano Biomedical Instruments, School of Mechanical Engineering, Southeast University, Nanjing, China have published the research work: Phononic origin of structural lubrication, in the Journal: (JOURNAL)
- what: The authors analyze the instantaneous frictional signals as a silicon tip sliding over a graphite substrate along different crystallographic directions using the fast Fourier transform (FFT), which clearly shows that phonons are mainly excited at the washboard frequency and its harmonics.
- how: In the experiment a single-crystalline silicon probe is employed . . .
