Several models have been used in literature studies to describe the mechanical behavior of hydroxyapatite (HA) polymer nanocomposites. However, previous models have often overlooked the size of HA and the properties of the interphase. In this study, we further develop an equation originally proposed by Kolarik. This advanced equation predicts the tensile strength of polymer/HA nanocomposites by considering the interphase parameter (A), rod‐like HA size, HA concentration, and interphase properties, including depth and strength. We validate our method using experimental data from various examples and through parametric inspections. Both the strength and the depth of the interphase directly affect the ‘A’ value and, consequently, the strength of the nanocomposites. For instance, an HA radius (R) of 6 nm yields the highest ‘A’ value of 4.97, enhancing the nanocomposite strength by up to 250%. In contrast, ‘R’ value of 20 nm fails to reinforce the samples effectively. Additionally, the thickness of the interphase (t) and the concentration of HA directly handle the nanocomposite strength. The strength of the samples significantly improves by 137% and 160% with an interphase thickness of 50 nm and an HA volume fraction of 0.2, respectively. Generally, the length of HA and interphase characteristics (thickness and strength) directly control the strength of samples, but the HA radius has an inverse relationship with nanocomposite strength.Highlights Kolarik equation is developed to predict the tensile strength of polymer HA nanocomposites. Interphase parameter, HA size, HA concentration and interphase properties are considered. HA radius of 6 nm produces the maximum enhancement of nanocomposite strength by 250%. Interphase properties and concentration of HA directly control the nanocomposite strength. All parameters reasonably influence the strength of samples confirming the developed model.

“…For bone implants, an application for which metallic alloys are usually used due to the lack of adsorption sites, a challenge in the deposition of coating materials such as hydroxyapatite (in its classical or modified structure) without any special technique, is the use of different chelating agents or adhesive materials, with no alteration of the coating properties [22][23][24].…”

In recent decades, coating materials have gained researchers’ interest, finding applications in different areas such as antimicrobial coatings for biomedical applications, coatings for increasing the shelf-life of commercial products, or coatings for the conservation of cultural heritage artifacts. The use of new types of coating materials based on natural ingredients can lead to the removal of harmful chemicals and contribute to the development of materials having different and promising properties. New challenges can appear both in the production process, as well as in the case of final application, when coating materials must be applied on various supports. The present review paper aims to be a critical discussion regarding the possibility of using natural ingredients as functional coatings, and to prove that the same material can be used in different fields, from the biomedical to environmental, or from cultural heritage protection to the food and cosmetic industries. The paper is based on the newest published studies, and its main goal is to be an inspiration source for researchers, in order to create more functional and applicable composite coatings in specific fields.

“…Traditional pollution treatment methods, such as physical adsorption and microbial treatment, have been unable to meet the needs of modern production; photocatalytic degradation of pollutants based on nanomaterials is an important direction for future development [1] . Nano-TiO2 is a new type of green environmental protection material, with strong photocatalytic performance, great thermal stability, and reusable characteristics [2] . At the same time, nano-TiO2 has the advantages of being non-toxic and low cost, which has attracted the attention of researchers.…”

Photocatalytic degradation of pollutants using nano-TiO2 is one of the most promising strategies to solve environmental pollution problems. In this paper, we systematically studied Bi2WO6 composited TiO2 nanowires to obtain the optimum composite proportion. Moreover, the TiO2 nanowires were composited with Bi2MoO6 and Bi2WO6/ Bi2MoO6 in the optimum proportion, respectively. The results showed that the Bi2WO6/ Bi2MoO6 composited TiO2 nanowires had the best catalytic performance, and the degradation rate of methyl orange reached 78.4%, which was 3.41 times higher than that of pure TiO2 nanowires. The current work is expected to provide new ideas for the research and development of high-efficiency photocatalytic materials.
