Descripción:
“...En el FTCC2 se encontraron matrices de morfología másplana, uniones intermoleculares fuertes, con microporos 3μm.Conclusiones: la estabilidad de las interconexiones mejora las propiedades mecánicas por asociación química entre las partículas del FTCC y el polialcohol, mediadas por elevada presión y temperatura; la regularidad del poro es el espacio liberado al fundirse el PVA.AbstractObjective: to compare microstructures of tricalcium phosphate atrices in Colombia (FTCC) using albumin, collagen, polyvinyl alcohol and varying pressure and temperature, electron microscopy confirmed scaninng (SEM). ...”Publicado 2015-06-12

“...The goals of this study were to investigate how the physical and mechanical properties of elasticity imaging phantoms change with time and moisture state.Two moisture states were tested; a dry state where the phantom was exposed to open air and a wet state where the phantom was submerged in water for 480 minutes. Polyvinyl alcohol (PVA) phantoms (cylindrical shape) were used. ...”
