Effects of Osseointegration by Bone Morphogenetic Protein-2 on Titanium Implants In Vitro and In Vivo by Fu-Yuan Teng, Wen-Cheng Chen, Yin-Lai Wang, Chun-Cheng Hung, Chun-Chieh Tseng

“…Three groups were compared with and without BMP-2 on modified titanium surfaces in vitro and in vivo: mechanical grinding; electrochemical modification through potentiostatic anodization (ECH); and sandblasting, alkali heating, and etching (SMART). Cell tests indicated that the ECH and SMART groups with BMP-2 markedly promoted D1 cell activity and differentiation compared with the groups without BMP-2. …”

Assessment on surface integrity in electrochemical grinding of AISI 304 by Mohammad Yazdani, Amir Rasti

“…Surface roughness decreased by up to 65 % in the perpendicular direction as concentration and voltage increased, but higher voltages led to over-etching, increased the surface roughness. Electrolyte concentration and voltage also reduced surface microhardness by 10–14 % through intensified corrosion, while higher wheel speeds increased microhardness due to enhanced mechanical removal. …”

Morphology of macropores in n-Si formed in NH4 F-containing solutions during photoanodization by V. V. Bolotov, I. V. Ponomareva, K. E. Ivlev

“…When comparing electrolytes with different pH (acidic and alkaline), a decrease in the pore diameter is observed at the same illumination and current densities in alkaline HF: NH4 OH solutions at a relatively equal etching rate in depth. In dilute HF: NH4 OH: H2 O under low illumination, there is a direct dissolution of silicon with the formation of a «starlike» pore morphology and a branching tendency. …”
