Polyhydroxyalkanoates(PHAs): sustainable biopolyester production

Polimery, 2002
Microbial polyhydroxyalkanoate (PHA) reserve polymers are interesting polyesters that can be sustainably produced by biotechnological means from a variety of renewable substrates. By feeding cosubstrates to selected cultures of prokaryotic microorganisms composition, structure and therefore physical properties of the PHAs can be influenced during their

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and
