“…Several in vitro and in vivo studies have been conductedto test the bioactivity and cell viability in such systems [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ], but reports on simple titanium (Ti)-impregnated systems are scarce [ 5 ]. In the biomedical field, Ti has a major physiological utility.…”

“…Previous studies have shown that the incorporation of TiO 2 in glasses not only improves their mechanical properties and stability but also increases the non-linear refractive index and ideally modifies the physical properties (density, molar volume, thermal expansion coefficient, glass transition temperature, etc.) [ 6 , 7 ]. By allowing the maintenance of biological activity, the addition of TiO 2 to glass-based systems leads to the development of biologically compatible and biologically active materials [ 8 , 9 ].…”

Intermediate water (IW) in hydrated bioactive glasses remains uninvestigated. We obtained titanium (Ti)-containing bioactive glasses (BGTs) (Ti at 5%, 7.5% and 10% of the glass system) using the sol–gel technique. Their thermal, physicochemical, and morphological properties, before and after Ti-doping, were analysed using DTA, XRD, FTIR, TEM, and SEM accessorised with EDAX, and size distribution and zeta potential surface charges were determined using a NanoZetasizer. The IW in hydrated BGTs was investigated by cooling and heating runs of DSC measurements. Moreover, the mode of death in an osteosarcoma cell line (MG63) was evaluated at different times of exposure to BGT discs. Ti doping had no remarkable effect on the thermal, physicochemical, and morphological properties of BGTs. However, the morphology, size, and charges of BGT nano-powders were slightly changed after inclusion of Ti compared with those of BGT0; for example, the particle size increased with increasing Ti content (from 4–5 to 7–28 nm). The IW content was enhanced in the presence of Ti. The mode of cell death revealed the effect of IW content on the proliferation of cells exposed to BGTs. These findings should help improve the biocompatibility of inorganic biomaterials.

“…Considering our previous experiences (Ref 26,27,28,29), APS and HVOF process parameters such as the flow rate of carrier gas, standoff distance between gun and substrate, robot arm velocity, and oxygen flow mass rate were chosen in order to obtain dense and thick coatings.…”

In this investigation, atmospheric plasma spray (APS) and high-velocity oxy-fuel (HVOF) techniques were used to produce AlCoCrFeNi coatings. High-entropy alloys (HEAs), due to their mechanical, chemical, and physical properties are capturing the attention of the international scientific community. Starting feedstock powders were characterized in terms of size, phase, and size, and corrosion test in NaCl, ball on disk, rubber wheel, and jet erosion tests was carried out on the obtained coatings. The results of the tribological investigation show that in the case of APS coatings, corrosion and wear behavior depend on the microstructure phases of the coating, as well as the amount of oxides. In particular, the wear morphology of APS surfaces is characterized by brittle fracture, with the presence of pores, cracks, and grooves. For HVOF coatings, further investigations on process parameters are needed because of the poor adhesion strength between the coating and the substrate. Anyway, the obtained corrosion resistance of HVOF coating is greater than that of the C steel substrate used to benchmark the results, and in addition, it ensures better performances in rubber wheel and jet erosion tests, but its wear resistance in the ball-on-disk test is worse because of the debris remaining in the wear track.

“…Besides the wet chemical methods, a third possible route to functionalize MOFs consists in using low temperature plasma treatments. Plasma treatments are widely used to functionalize different materials like polymers [47][48][49], cotton [50][51][52], wood [53][54][55], glass [56][57][58], metals [59][60][61]. The dry plasma processes used for the elaboration and functionalization of materials are varied.…”
