Effect of iron doped hydroxyapatite nanoparticles on the structural, morphological, mechanical and magnetic properties of polylactic acid polymer A Study on Mechanical Properties of PMMA/Hydroxyapatite This study is focused on the role of nano hydroxyapatite particles on the mechanical properties of PMMA/HA nanocomposites. In order to achieve a proper and homogeneous distribution of HA particles in the polymer matrix, mixer milling process was applied. Wear, compression and three-point bending tests were conducted. It was observed that wear rate decreased by increasing in HA content in both

Effect of different hydroxyapatite incorporation methods

Using freeze-dried collagen-based scaffolds as an analogue of native ECM, we sought to improve the mechanical properties by incorporating hydroxyapatite (HA) in different ways while maintaining a pore architecture sufficient to allow cell infiltration, vascularisation and effective bone regeneration. Effect of iron doped hydroxyapatite nanoparticles on the Apr 01, 2019 · The structural, morphological, mechanical and magnetic properties of these substrates were properly discussed and evaluated. Further, the antibacterial activity for PLA/FeHA nanocpomposites was determined. These magnetic nanocomposites can be utilized as a fixed station that can be manipulated in situ through applying external magnetic Effect of magnetite nanoparticles on the biological and Jun 01, 2020 · S. Sahmani, S. Saber-Samandari, A. Khandan, M.M. AghdamInfluence of MgO nanoparticles on the mechanical properties of coated hydroxyapatite nanocomposite scaffolds produced via space holder technique:fabrication, characterization and simulation

Effects of hydroxyapatite reinforcement on the

Freeze-dried collagen scaffolds reinforced with hydroxyapatite (HA) are of clinical interest for synthetic bone graft substitutes and tissue engineering scaffolds, but a systematic evaluation of the effects of the HA reinforcement weight fraction and morphology on the mechanical properties is lacking. Enhancement of mechanical properties of hydroxyapatite The addition of bioinert ceramics such as alumina and zirconia can significantly improve the mechanical properties of hydroxyapatite bioactive coatings and increase their biocompatibility. In the present study, the surface of a titanium substrate was coated by the electrophoretic deposition method (EPD). Hydroxyapatite ::properties, uses and applications Hydroxyapatite (HAp) is a calcium phosphate similar to the human hard tissues in morphology and composition. Due to its outstanding properties such as biocompatibility, bioactivity, osteoconductivity and non toxicity and non inflammatory nature, nano-hydroxyapatite bioceramic has got a variety of applications in medical and oral care areas.

Materials Free Full-Text Mechanical Properties of Nov 23, 2020 · Nanotechnology is a very attractive tool for tailoring the surface of an orthopedic implant to optimize its interaction with the biological environment. Nanostructured interfaces are promising, especially for orthopedic applications. They can not only improve osseointegration between the implant and the living bone but also may be used as drug delivery platforms. Mechanical Properties of Hydroxyapatite Doped with Hydroxyapatite is a biomaterial, more exactly a bioceramic, from a category of materials frequently used in bone implants. In order to improve mechanical properties, hydroxyapatite is doped with different chemical substitutes, among which the most used are:Mg2*, Zn 2*, La3*, Y3*, In3* Bi3* CO32-, Si and Mn. In the paper are presented the modality of obtaining hydroxyapatite doped with

Mechanical properties of highly porous PEEK

Oct 19, 2019 · Bone regeneration is of great importance worldwide, because of various bone diseases, such as infections, tumors, and resultant fracture, birth defects, and bone loss due to trauma, explosion, or accident. Bone regeneration can be achieved by several materials and templates manufactured through various fabrication techniques. Uses of different materials and scaffold fabrication techniques Mechanical properties of sintered hydroxyapatite for The compressive, flexural, torsional and dynamic torsional strengths of polycrystalline hydroxyapatite sintered at a temperature of 1300° C for 3 h were found to be 509, 113, 76 and 68 MPa, respectively. The mechanical properties of polycrystalline hydroxyapatite are compared with those of cortical bone, dentine and enamel. SEM observation of the fracture surfaces indicates a predomination of Nanosized hydroxyapatite and other calcium phosphates Sunil Kumar, Chandkiram Gautam, Brijesh Singh Chauhan, Saripella Srikrishna, Ram Sagar Yadav, Shyam Bahadur Rai, Enhanced mechanical properties and hydrophilic behavior of magnesium oxide added hydroxyapatite nanocomposite:A bone substitute material for load bearing applications, Ceramics International, 10.1016/j.ceramint.2020.03.180, (2020).

Sintering Effect on Mechanical Properties of Composites of

In this study, hydroxyapatite (HA) material, obtained from calcinated bovine bone (BHA), was mixed with 0.25, 0.50, 1.00, and 2.00 wt% Li2CO3. The pressed pellets were sintered at various sintering temperatures between 900°C and 1300°C. Measurements of compression strength, microhardness, and density, along with SEM observation and X-ray diffraction analysis were performed. Structure and properties of nano-hydroxyapatite/poly Biodegradable polymers, because their degradation products are small molecules that do not cause immune system rejection, have been increasingly used by researchers to explore the preparation of scaffold with excellent mechanical properties, biocompatibility and biodegradability. In this study, nano Mechanical properties of hydroxyapatite formed at Mar 01, 1995 · The mechanical properties of monoliths of calcium-deficient and carbonated hydroxyapatite formed by dissolution-precipitation reactions at 38°C have been determined. Particulate solid reactants were mixed at liquid-to-solid weight ratios of 0.11 and 0.2 and pressed into various configurations on which mechanical tests were carried out. Testing was performed on wet had formed.
