Silicon-doped biphasic alpha-calcium-phosphate/hydroxyapatite scaffolds obtained by a replica foam method using uniform pre-annealed spherical particles
(Elsevier Science Bv, Amsterdam, 2012)
In this study, spherical particles of hydroxyapatite (HA) and alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2): alpha-TCP) doped with different amounts of silicon were used for the preparation of scaffolds. The scaffolds ...
Conceptual design for treatment of mining and metallurgical wastewaters which contains arsenic and antimony
(Association of Metallurgical Engineers of Serbia, 2012)
This paper presents a preliminary design for treatment of mining and metallurgical wastewaters (MMW) from the basin of antimony 'Zajača', which contains high concentrations of arsenic and antimony. MMW have been investigated ...
Effects of operating parameters on efficiency of lead removal by complexation-microfiltration process / Uticaj radnih parametara na efikasnost uklanjanja jona olova pomoću kompleksirajuće-mikrofiltracionog procesa
(Association of Chemical Engineers of Serbia, 2012)
The majority of lead content found in the environment is a result of human activities. Heavy metals can be hazardous because they tend to bioaccumulate. A complexation-microfiltration process for the removal of Pb(II) ions ...
