Poly(styrene- alt-maleic acid) adsorption on hydroxyapatite and TiO2 (rutile) was studied using experimental techniques and complemented by ab initio simulations of adsorption of a maleic acid segment as a subunit of the copolymer. Ab initio calculations suggest that the maleic acid segment forms a strong covalent bonding to the TiO2 and hydroxyapatite surfaces. If compared to vacuum, the presence of a solvent significantly reduces the adsorption strength as the polarity of the solvent… 

A review on hydroxyapatite coatings for the biomedical applications: experimental and theoretical perspectives.

The main significance of this review is to present a collective discussion on the structural features, interfacial mechanics and binding aspects by experimental and theoretical investigations for HAP-based biomaterials, which can provide clear insights for the future research related to orthopedic applications.

Probing the surface activity of hydroxyapatite nanoparticles through their interaction with water molecules

Hydroxyapatite nanoparticles (nano-HAPs) are often used to promote the performance of various biomaterials, but their surface activity can be hardly evaluated directly. An indirect approach of using

Sol-gel synthesis is used to obtain coatings that can modify the surfaces of metals to avoid corrosion or to enhance the biocompatibility and bioactivity of metals and their alloys that are of

Nano-Hydroxyapatite Encapsulated inside an Anion Exchanger for Efficient Defluoridation of Neutral and Weakly Alkaline Water

The efficient removal of fluoride from weakly alkaline groundwater still remains a great challenge, owing to the high hydration energy of fluoride. Herein, we conducted in situ precipitation of nan...



Adsorption-Desorption Behavior of Acrylic-Maleic Acid Copolymer at Clay Minerals

The interactions between acrylic-maleic acid (PAA-PMLA) copolymer with clay minerals are investigated in terms of adsorption/desorption behavior and effects due to the heterogeneity of the kaolinite surface and to the conformation of the adsorbed PAA- PMLACopolymer are discussed.

Copolymers of maleic acid and their amphiphilic derivatives as stabilizers of silver nanoparticles.

Under optimal reduction conditions, the final morphology of Ag nanoparticles is governed by structural similarity (strict alternation of monomer units and similar polymer chains length of all copolymers; hydrophobic ligands only assist in stabilization of nanoparticles.

Density functional theory and experimental studies of caffeic acid adsorption on zinc oxide and titanium dioxide nanoparticles

The outstanding adsorption properties of proteins, containing catecholic amino acid, L-3,4-dihydroxyphenylalanine (DOPA), and recent advances in nanoparticle functionalization using molecules from

The effects of hydroxyl groups on Ca adsorption on rutile surfaces: a first-principles study

Results reveal that an oxidized rutile surface has the highest ability to attract Ca atoms, which partially explains that alkali-treated Ti surfaces could induce hydroxyapatite formation in alkaline environments.

Role of Concentration on the Formulation of Zinc Oxide Nanorods from Poly(styrene-alt-maleic acid) Template

The self-assembled nanotube structure of poly(styrene-alt-maleic anhydride) derivatives had been previously ascribed to its favorable chirality on the polymer chain. Therefore,
