ACI

Autologous Chondrocyte Implantation A technique for the treatment of large isolated cartilage defects. A small sample of cartilage is harvested from a non-weight-bearing part of the joint during arthroscopy. In a laboratory the chondrocytes are dissolved away of the tissue composite and multiplied in culture dishes. After a cultivation period of 3 to 4 weeks …

ALD

Atomic Layer Deposition ALD uses timed pulses of reactive precursors to encapsulate all exposed surfaces of a substrate for coating. It gets its name from the nature of these pulses, each of which deposits a single self-terminating layer.  It is a subclass of chemical vapour deposition (CVD). The coating can be controlled with atomic precision.
