“…The authors also proposed the effective order of reactants deposition on the stone (the phosphate followed by the calcium source) and drew attention to a possible drawback of the method, respectively an elevated risk of yellowing on the surface. A particular approach was developed by our group, regarding the application of synthesized hydroxyapatite and apatitic materials, especially for the protection of limestone, but also for antimicrobial purposes [111][112][113][114]. However, due to the significant color changes recorded, the optimization of these recipes still represents a subject for future research.…”

Vernacular buildings are usually constructed using materials at hand, including wood, natural stone and bricks (either clay or mud bricks). All those materials are exposed to a series of environmental factors, affecting their structure and integrity. The literature review was conducted using different databases (Scopus, Web of Science, ScienceDirect, SpringerLink) using as keywords the historical material, "heritage" and the terms regarding the desired effect, within the envisaged time period (2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019). The assessment of the results was performed by manual inspection (reading the entire article) and the selection of the works to be inserted in the current review was made by evaluating the contribution to the field. This review summarizes different aspects related to the restoration and conservation of wooden and masonry elements of traditional buildings, including materials used for biocidal interventions, protection against abiotic factors, cleaning and consolidation agents. Finally, a critical discussion regarding the current limitations and future perspectives concludes the review work, envisaging the role of researchers specialized in materials science in the context of cultural heritage conservation.

“…

The literature provides us several examples of apatitic materials in whose structure the calcium ions are substituted by different metals, which are remarkable for their applicability in heritage conservation, bioremediation, and biomedicine [1][2][3][4]. According to the desired properties, several methods were developed to obtain these apatitic materials.

“…According to the desired properties, several methods were developed to obtain these apatitic materials. The decoration of the apatitic structure with metal and metal oxide nanoparticles is far less studied, even though it provides the development of more economical materials, using mild reaction parameters [2].Hydroxyapatite was prepared according to a recipe developed before in the laboratory [4]. For the incorporation of copper in the hydroxyapatite's structure, we studied two approaches: the decoration of hydroxyapatite with metal nanoparticles and metal oxide nanoparticles.…”

“…For the incorporation of copper in the hydroxyapatite's structure, we studied two approaches: the decoration of hydroxyapatite with metal nanoparticles and metal oxide nanoparticles. The copper nanoparticles were obtained using a modified Turkevich method [2]. The decoration of the apatitic materials was achieved post-synthesis, using metallic oxide nanoparticles and metallic ions.To confirm the nanoparticles' synthesis, the obtained materials were subjected to UV-Vis spectroscopy.…”

In this work, novel magnetic nanocomposites, Fe 3 O 4 @Ba 3 (PO 4) 2 (denominated FBP) nanoflakes loaded with Ag nanoparticles (NPs) (denominated FBPA), were reported for cleaning E. coli from water. FBPA with 1 wt% Ag (denominated FBPA1) showed a higher adsorption efficiency (94%) than FBPA with 10 wt% Ag (denominated FBPA10), for water heavily contaminated with E. coli (5 Â 10 8 CFU/mL), both at a dosage of 1 g/L within 10 min. Importantly, the loaded Ag NPs can greatly improve the disinfection effect of FBP due to the great antimicrobial activity of Ag NPs via the released Ag þ. Confocal fluorescent images and dilution plating results showed that~100% of E. coli could be inactivated by FBPA1 within 10 min. The calculated disinfection capacity was higher than some other materials. Three co-existed salts in solutions decreased the disinfection efficiency of FBPA1 to be~67% (NaCl),~59% (CaCl 2), and~41% (MgCl 2). Furthermore, FBPA1 can be reclaimed via a magnet to be reused. FBPA1 maintained an adsorption efficiency of 86%, disinfection effect of 70%, and~90% of loaded Ag NPs after the fifth recover and reuse cycle.
