On the Ionisation Fraction in Protoplanetary Disks II: The Effect of Turbulent Mixing on Gas--phase Chemistry [PDF]
, 2005 We calculate the ionisation fraction in protostellar disk models using two different gas-phase chemical networks, and examine the effect of turbulent mixing by modelling the diffusion of chemical species vertically through the disk.

Advanced Engineering Materials, EarlyView.Grinding chips of high‐alloyed steel are prepared to be admixed to a starting powder mixture for laser powder bed fusion. A three‐stage preparation is performed, including washing in acetone, magnetic separation, and ball milling. The addition of 30% of grinding chips to the powder mixture allows the fabrication of dense samples.
