The friction force opposing the onset of motion of a drop on a solid surface is typically considered to be a material property for a fixed drop volume on a given ***,here we show that even for a fixed drop volume,the static friction force can be tuned by over 30%by preshaping the *** static friction usually exceeds the kinetic friction that the drop experiences when moving in a steady *** forces converge when the drop is prestretched in the direction of motion or when the drop shows low contact angle *** contrast to static friction,kinetic friction is independent of preshaping the drop,that is,the drop *** friction forces reflect the material properties.

Efficient manipulation of spin waves (SWs) is considered as one of the promising means for encoding information with low power consumption in next-generation spintronic devices. The SW Doppler shift is a key phenomenon obtained by manipulating SW propagation. Here, we predict an efficient way to control the SW Doppler shift by voltage-control magnetic-anisotropy-boundary (MAB) movement in the FM-FE heterojunction. From the micromagnetic simulation, we verified that the SW Doppler shift aligns well with our theoretical predictions in Fe/BaTiO3 heterostructure. The SW Doppler shift also shows an ultra-wide-band-shift (over 5 GHz) property with voltage. Such an efficient SW Doppler shift may provide one possible way to measure the Hawking radiation of an analogue black hole in the SW systems.
