TAGHIZADEH TOUSI, Ehsan et al. Characterization of the rhizophora particleboard as a tissue-equivalent phantom material bonded with bio-based adhesive. Maderas, Cienc. tecnol. [online]. 2015, vol.17, n.2, pp.305-318.  Epub 01-Mar-2015. ISSN 0718-221X.  http://dx.doi.org/10.4067/S0718-221X2015005000029.

In this study, some characteristics of Rhizophora spp. particleboards bonded with Serishoom (traditional animal-based adhesive) as a phantom material was investigated. The Rhizophora spp. particleboards were fabricated in two Serishoom adhesive treatment levels (6% and 12%) with three Rhizophora spp. particle sizes (≤ 149 µm, 149 µm - 500 µm, and 500 µm - 1000 µm) at 1 g.cm-3 of the target density. The internal bond strength and the dimensional stability of the Serishoom-bonded Rhizophora spp. particleboards were improved by using the smaller Rhizophora spp. particle size and the higher Serishoom adhesive treatment level. The effective atomic numbers of the Serishoom-bonded Rhizophora spp. particleboards were determineted to be 7,56 to 7,58 by an energy dispersive X-ray, which is in good agreement with those of water and breast tissue. In addition, the density distribution profiles of the fabricated Serishoom-bonded Rhizophora spp. particleboards were determined by the Kriging method with the use Surfer8 computer software, which indicated that there was good density homogeneity throughout the Serishoom-bonded Rhizophora spp. particleboards. The results showed a potential of the Serishoom-bonded Rhizophora spp. particleboard bonded with Serishoom to be used as a phantom material.
