Hydrolysis of monetite/chitosan composites in α-MEM and SBF solutions

Journal of Materials Science: Materials in Medicine, 2011
There are two objectives of this work. The first objective is to study the hydrolysis behavior of monetite cements formed in the presence and absence of the chitosan in cell culture media (α-MEM) and simulated body fluid (SBF) solutions at 37°C. During hydrolysis, monetite transformed to carbonated apatite. Therefore, the second objective is to examine

Scaffold microstructure evolution via freeze‐casting and hydrothermal phase transformation of calcium phosphate

Journal of the American Ceramic Society, Volume 107, Issue 12, Page 7994-8006, December 2024.
Scaffolds with enhanced porosity and altered surface morphologies were created through freeze‐casting, sintering, and subsequent hydrothermal treatment. The modified scaffolds maintained their overall macrostructure, displaying high porosity (≥60%), diverse hydroxyapatite phase ratios (0–99%), and a compressive strength of 5.7 MPa.

Composite brushite-monetite-newberyite cements loaded with vancomycin and their efficiency against infections of: In vitro and in vivo research

Open Ceramics
Composite cements containing brushite, monetite and newberyite as dominating phases were created and used as drug (vancomycin) carriers. Brushite-monetite-newberyite cement with variable composition was obtained by replacing Ca2+ ions with Mg2+ in the ...

Is Struvite a Prebiotic Mineral?

Life, 2013
The prebiotic relevance of mineral struvite, MgNH4PO4·6H2O, was studied experimentally as a phosphorylating reagent and, theoretically, to understand the geochemical requirements for its formation.

Calcium Phosphates: A Key to Next‐Generation In Vitro Bone Modeling

Advanced Healthcare Materials, Volume 13, Issue 29, November 22, 2024.
The review examines the need for in vitro bone models focusing on the role of calcium phosphates (CaP). It discusses CaP’s contributions to cell types, nutrient supply, and mechanical strength, while addressing challenges like compositional variability and instability.

A Probabilistic Approach to Phosphorus Speciation of Soils Using P K-edge XANES Spectroscopy with Linear Combination Fitting

Soil Systems, 2020
A common technique to quantitatively estimate P speciation in soil samples is to apply linear combination fitting (LCF) to normalized P K-edge X-ray absorption near-edge structure (XANES) spectra.

Preparation of Dicalcium Phosphate Anhydrous (Monetite) Biological Coating on Titanium by Spray-Drying Method

Advances in Materials Science and Engineering, 2017
Titanium and its alloys have been widely used in the manufacture of endosseous implants due to excellent biocompatibility, low elastic modulus, and good chemical stability. However, the titanium based metals are essentially bioinert materials.
