The intramolecular H-bond to either O3 or O4 leads to such a symmetrical energy barrier for ϕ1. Those interactions were found in the crystal structure of CDHB, as described below. However, the rotation along the ϕ3 coordinate is much more restrained. The barrier between the K1 and K...
The most suitable techniques with better results are: SLA and printing-based inkjet [43]. An additional problem is the printing of the vascular networks of organs and tissues which still has not been resolved but, it is estimated that in less than 20 years it will be possible to print a ...
