The synthesis of apatite silicated Ca10(PO4)6-x(SiO4)x(OH)2-x (SiHA) with 0?x?2 was investigated using a wet precipitation method followed by heat treatment calcium carbonate CaCO3 and phosphoric acid H3PO4 silicon tetraacetate SiC8H20O4 (TEOS) in medium water ethanol, three different silicate concentrations. After drying, the samples are ground then characterized analytical techniques like X-r...

In the quest to increase quality of life and expectancy, there is a great demand develop advanced medical devices capable facing current health challenges. Santa Barbara Amorphous (SBA-15) mesoporous silica has been demonstrated be remarkable option for variety biomedical applications, from tissue engineering drug delivery, due its unique hierarchical porous structure. This work reports on effe...

Hydrothermal liquefaction (HTL) is known to be a promising technology produce crude bio-oils as intermediate drop-in transport fuels. However, the co-production of wastewater (HTL-AP) and hydrochar residues (HCs) limits economic viability technical scalability. Hence, objective this work study effect catalysts NaOH,KOH,Na2CO3,K2CO3,H3PO4,FeCl3andFe2O3 in HTL reaction medium on characteristics d...

Titanium is a highly reactive metal so that a thin layer of oxide forms on its surface whenever exposed to the air or other environments containing oxygen. This layer increases the corrosion resistance of titanium. The oxide film is electrochemically formed through anodizing. In this study, anodizing of titanium was performed in phosphate-base solutions such as H3Po4, NaH2Po4, and Na2Hpo4 at 9....
