Abstract Apatite-related zirconium, carbonate and zinc-containing calcium phosphates have been synthesized in aqueous solutions at different molar ratios Ca2+ : Zr4+ Zn2+ PO43- CO32- = (10-2x-y/2-z) x y (6-z) z (x 0.05, 0.1, 0.5 1.0; 0.5, 0, 0.5) heated to 600 oC during 2 hours. X-ray powder diffraction FTIR spectroscopy data confirmed the formation of single phase modified apatite-related with partial substitution by anionic sublattice (B-type). The calculated lattice parameters for prepared Zr4+, Zn2+- correlate amount dopants their composition. sizes do not depend on composition initial solution vary range 30-45nm. highest antimicrobial effect against Staphylococcus aureus strain was found phosphate Ca9Zr0.5(PO4)6(OH)2 (at its adding 10 mM). Modification Zr-containing anion decreased Pseudomonas aeruginosa survival ten times.

The development of biocompatible nanofibres through electrospinning is a promising method for engineers in the biomedical field. existing coating technologies medical field have various limitations, and more investigations are needed to improve their biocompatibility, controlled release properties, mechanical strength. Designing new materials that can interact efficiently with biological systems offer numerous functional advantages major challenge device manufacturing tissue engineering. This chapter reviews approaches used create nanofibres, including design, fabrication functionalization. applications these coatings also reviewed. Furthermore, we discuss methods, used, key parameters impact fibre morphology physiochemical properties. Moreover, incorporation bioactive elements drugs into therapeutic explored. biologically friendly be an effective approach improving coatings. Such enhance properties such as drug delivery, regeneration, implant integration, offering enormous potential patient welfare. Future research areas include investigating use advanced procedures enhanced control over nanofibre composition design fabrication.

BACKGROUND: Atherosclerosis is a condition which disrupts blood flow due to plaque build-up inside the arteries. Under conditions where consecutive plaques are prevailing hammer principle exhibited. OBJECTIVE: The pressure and shear stress produced at an infinitesimal area act as governing equation for stent modeling. leading order lays foundation design of cardiac stents with definite dimensions. METHOD: designed was encapsulated crimper validated through ANSYS-static transient structural simulation derive total deformation, equivalent strain, exerted on stent. Five different biomaterials stainless steel 316, cobalt, chromium, platinum, Poly lactic acid were selected material assessment. RESULT: Static Transient analysis period 1 10 secs implemented without crimper. performance in terms stress, strain analyzed. CONCLUSION: paper envisions dynamics atherosclerosis that provides changes clotting process. It shows promising results behavior varied forces gives valuable insights future improvement selection.

Hydroxyapatite (HAP) is a widely used biomaterial due to its excellent bioactivity, biocompatibility, and structural similarity the mineral component of human bone teeth. However, synthesis HAP typically relies on expensive non-renewable precursors, which can limit widespread applications. This study investigates extraction purification from cockle shells, are readily available renewable source calcium carbonate. The hydroxyapatite rich in carbonate, promising method for producing biomedical applications bioactivity biocompatibility. use calcination process wet slurry precipitation technique produce seashells, focusing effect reaction time phosphate (KH2PO4) oxide (CaO) production. EDX reported Ca/P ratio 1.61 synthesized by chemical 2 hours reaction. Meanwhile, XRD results indicate that 4-hour produces more crystalline than shorter times, highlighting importance synthesis. research demonstrates potential utilizing seashell waste as valuable natural resource healthcare management.
