Bacterial behavior on coated porous titanium substrates for biomedical applications
(Elsevier, 2019)
In this work, bacterial behavior on dense and porous titanium substrates is discussed. Porous titanium was fabricated by a space holder technique (using 50 vol%, NH4HCO3 with particle sizes between 250 and 355 μm). These ...
