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.

ABSTRACT To examine natural bone's bioelectrical traits, notably its piezoelectricity, and to look into how these characteristics influence bone growth repair. In the context of exploring potential piezoelectric biomaterials, such as biopolymers bio‐ceramics, towards orthopedic regeneration applications, research seeks evaluate significance piezoelectricity‐driven osteogenesis. The paper reviews recent on electrical dielectric properties, surface polarization/electrical stimulation effects interacting with cell activity effectiveness biomaterials support tissues' regenerative process. study includes a number materials, collagen, polyvinylidene fluoride (PVDF) barium titanate. applications organic polymers, polymers are particularly highlighted. Piezoelectric being shown in studies enhance cellular metabolism vitro well promote tissues vivo, especially when paired electric field or interface polarization. bio‐ceramics like magnesium silicate titanate, collagen PVDF, have possibilities for applications. However, there several challenges regarding manufacturing specific compositions having desired properties. This review highlighted special emphasis bioceramics. Therefore, types materials huge because they can mimic properties allow better advances tissue engineering medicine. date, little is known about their mechanism action, modifications needed improve efficacy clinical uptake.

Cancer treatment has historically depended on conventional methods like chemotherapy, radiation, and surgery; however, these strategies frequently present considerable limitations, including toxicity, resistance, negative impacts healthy tissues. In addressing challenges, drug-free cancer therapies have developed as viable alternatives, utilizing advanced physical biological to specifically target tumor cells while reducing damage normal This review examines several strategies, such high-intensity focused energy beams, nanosecond pulsed electric fields, photothermal therapy well the use of inorganic nanoparticles promote selective apoptosis. We also investigate significance targeting microenvironment, precision medicine, immunotherapy in progression personalized therapies. Although approaches demonstrate significant promise, challenges scalability, safety, regulatory obstacles must be resolved for clinical application. paper presents an overview current research therapies, emphasizing recent advancements, underlying scientific principles, steps required implementation.

Abstract The increasing global demand for clean water has driven significant research into solar steam generation and purification technologies. Hydroxyapatite (HAp), a biocompatible chemically stable material, demonstrated promise treatment due to its excellent adsorption properties. However, microbial contamination poses challenge in application generation. Herein, novel macroporous silver-doped hydroxyapatite (Ag-HAp) nanocomposite was used the first time fabricating photothermal membranes. incorporation of Ag Ag-HAp significantly alters structure, introducing voids, which are transportation release results show that membrane achieved an evaporation rate 1.202 kgm− 2h− 1 under one-sun illumination, 1.33-fold increase compared pure HAp Additionally, antibacterial evaluations using disc diffusion method revealed activity against Escherichia coli Staphylococcus aureus, with inhibition zones concentration. These findings highlight potential nanocomposites as efficient durable solution harvesting purification.
