Polyaniline (PANI) has recently gained great attention due to its outstanding electrical properties and ease of processability; these characteristics make it ideal for the manufacturing of polymer blends. In this study, the processing and piezoresistive characterization of polymer composites resulting

Although porous polyethylene (PPE) implants are already used in reconstructive craniofacial surgery, they are still only applied in rhinoplasty when critically indicated. Biocompatibility of PPE implants (pore size ~100-200 µm) can be modified by tissue engineering: coatings with extracellular matrix
