Although magnesium (Mg) is a unique biodegradable metal which possesses mechanical property similar to that of the natural bone and can be an attractive material to be used as orthopedic implants, its quick corrosion rate restricts its actual clinical applications. To control its rapid degradation, we have modified the surface of magnesium implant using fluoridated hydroxyapatite (FHA: Ca10(PO4...

Several studies were carried out in order to reduce the systemic use of antibiotics due to the high concentration required to provide the minimum inhibitory concentration (MIC) at infected sites. The aim of this study was to develop a system of drug adsorption onto commercial hydroxyapatite (HA, Ca10(PO4)6(OH)2) and glass reinforced hydroxyapatite (GR-HA) granules. The drug will then be release...

The presence of fluoride, lithium and carbonate group within hydroxyapatite occurring naturally the body provides basis for investigating sintering ability co-substituted hydroxyfluorapatites nanopowders use as biomaterials. Ca10-xLix(PO4)6-x(CO3)x(OH)F nanopowders, with x equal to 0, 0.5, 1, 1.5, 2 2.5 were prepared using mechanosynthesis their extensive characterization was realized. Substitu...

Hydroxyapatite (Ca10(PO4)6(OH)2, HAp), due to its high biocompatibility, is widely used as biomaterial. Doping with various ions of hydroxyapatite performed acquire properties close possible the biological apatite present in bones and teeth. In this research results a study on thin films co-doped nitrogen bromine (NBrHAp) are presented for first time. The NBrHAp suspension was obtained by perfo...

Converting biowaste into biochar and incorporating it soil is recognized as an effective method for carbon (C) sequestration. However, inevitably undergoes aging process in soil, which influences its stability, ultimately threatens sequestration ability. This study selected CaCl2 exogenous additive of sewage sludge bone dreg producing Ca-rich biochars, both surface C bulk stability them were in...

Hydrogen is a clean and renewable alternative fuel. In this paper, the combustion mechanism of diesel/hydrogen dual fuel constructed verified. The combined with three-dimensional numerical simulation to study effects pilot injection main on emissions engine. uses 70% mole fraction n-decane 30% α-methylnaphthalene as diesel substitutes, it combines n-decane, α-methylnaphthalene, NOX, PAH, soot H...

Hydroxyapatite (Ca10(PO4)6(OH)2) calcium phosphate is a robust and viable magnetic material for the treatment of polluted air, water, soil. Because its unique structure appealing properties such as high adsorption capabilities, acid-base adaptability, ion-exchange capability, thermal stability, hydroxyapatite (HAp) has lot potential in field environmental management. An aqueous extract Monoon l...
