“…Still, it is worth pointing out that their inclusion in the NBC/MXene composite during the manufacturing of medical dressings and bandages increases the effectiveness of treating superficial wounds by significantly reducing the activity of bacteria. Such metals could be Au, Ag, Zn, Cu, ZnO, and Fe 2 O 3 [178][179][180][181][182][183][184]. The research on these composite materials will be actively conducted soon.…”

MXene exhibits impressive characteristics, including flexibility, mechanical robustness, the capacity to cleanse liquids like water through MXene membranes, water-attracting nature, and effectiveness against bacteria. Additionally, bacterial cellulose (BC) exhibits remarkable qualities, including mechanical strength, water absorption, porosity, and biodegradability. The central hypothesis posits that the incorporation of both MXene and bacterial cellulose into the material will result in a remarkable synthesis of the attributes inherent to MXene and BC. In layered MXene/BC coatings, the presence of BC serves to separate the MXene layers and enhance the material’s integrity through hydrogen bond interactions. This interaction contributes to achieving a high mechanical strength of this film. Introducing cellulose into one layer of multilayer MXene can increase the interlayer space and more efficient use of MXene. Composite materials utilizing MXene and BC have gained significant traction in sensor electronics due to the heightened sensitivity exhibited by these sensors compared to usual ones. Hydrogel wound healing bandages are also fabricated using composite materials based on MXene/BC. It is worth mentioning that MXene/BC composites are used to store energy in supercapacitors. And finally, MXene/BC-based composites have demonstrated high electromagnetic interference (EMI) shielding efficiency.

“…The deposition of CaP coatings on the implant surface increases biocompatibility and accelerates the fixation of the implant material in the bone. There are a number of fabrication methods for the deposition of CaP coatings: sol-gel coating [5], plasma spraying [6], electrophoretic deposition [7], micro-arc oxidation (MAO) [8], chemical vapor deposition, [9] pulsed laser deposition [10], ion beam deposition [11] and magnetron sputtering [12]. Some researchers [13,14] have suggested to combine these methods for deposition of CaP coatings.…”

The micro-arc oxidation method has been used to obtain bioactive calcium-phosphate coatings on titanium surface. The effect of the pulse current duty cycle and voltage of micro-arc oxidation on the morphology, elemental and phase composition of the coating has been studied. Decrease in the pulse duty cycle during microarc oxidation results in the formation of flake, spheroidal and lamellar structures. It has been shown that the Ca/P ratio and surface roughness of the coating increases regardless of the pulse duty cycle with increase of applied voltage. Depending on the application mode, the Ca/P ratio and the roughness of calcium phosphate coatings ranged from 0.44 to 0.67 and from 4.2 to 6.8 μm, respectively. It was found that change of the pulse current duty cycle and increase of the voltage up to 600 V results in the formation of the main crystalline phases Ca(H2PO4)2(H2O) and CaPO3(OH) in the coatings.

“…It is important to obtain a layer of hydroxyapatite (HA) on the surface, as it is an inorganic component of bone tissue that stimulates the fusion of bone with the implant, which can shorten the treatment time and reduce the risk of rejection of the implant by the body. Another important factor is the formation of micropores during the PEO process, which allows cells to adhere and proliferate [26,27]. Furthermore, the application of PEO is often related to simplicity, cost-effectiveness, and a quick process time.…”

In this article, the process of creating calcium phosphate coatings through plasma electrolytic oxidation was investigated. Calcium phosphate coatings were deposited onto titanium substrates fabricated via the selective laser melting (SLM) method. The correlation between the characteristics of the coating and the applied voltage (200, 250, and 300 V) of PEO was studied. The surface morphology analysis indicates that an increase in applied voltage results in a larger pore size. It was discovered that, when a voltage of 300 V was applied, a layer of hydroxyapatite formed. However, at 300 V, the coating cracked, producing a significantly rough surface. Our analysis of the elemental composition of sample cross sections indicates the presence of TiO2 layers that are enriched with calcium (Ca) and phosphorus (P). The coefficient of friction and wear rate are primarily influenced by the morphology, pore size, and density of the titanium dioxide layer. Furthermore, a rise in the quantity of the beta phase of the titanium on the surface can be noticed as the applied voltage increases. As a result, it also affects the mechanical and tribological characteristics of the coating. The sample treated to a voltage of 250 V demonstrates a higher resistance to wear and a lower elastic modulus in comparison to the other two coatings.
