Researchers find how cells move while avoiding adhesion

Cancer cells moving on glycoproteine strips: These strips act like splints, which allow to control and to study the movement of the cells better. Credit: Rädler Lab, Ludwig Maximilians Universität München Cell velocity, or how fast a cell moves, is known to depend on how sticky the surface is beneath it, but the precise mechanisms […]

A route for avoiding defects during additive manufacturing — ScienceDaily

Laser powder bed fusion is a dominant additive manufacturing technology that has yet to reach its potential. The problem facing industry is that tiny bubbles or pores sometimes form during the printing process, and these pores create weak spots in finished products. When a slow-speed, high-power laser is melting metal powder during the 3D printing […]

Artwork showing the boundary and origin of keyhole porosity. On the left side of the figure, the keyhole porosity boundary in the laser power – scan velocity space is sharp and smooth. On the right side, around the porosity boundary, the critical keyhole instability releases acoustic waves (shock waves) in the melt pool. The waves […]
