“…Compared with activated CAU-23, the sample of CAU-23 adsorbed with CR showed larger and higher content of the characteristic peaks in C–C, SO, −SO 3 , and more characteristic peaks in NN and −NH 2 (Figure S5), all indicating the successful adsorption of CR by CAU-23. The Al 2p spectra of native CAU-23 yielded Al–O and Al–OH peaks at 73.86 and 73.03 eV, respectively . After adsorption, the Al–O and Al–OH peaks shifted to 73.03 and 72.86 eV, respectively.…”

Pollution of water resources by industrial dyes can threaten environmental safety and human health even at low concentrations. We proposed the adsorption removal of a typical azo dye, Congo red (CR), by CAU-23, an aluminum-based metal–organic framework (MOF). To characterize CAU-23, X-ray diffraction (XRD), Fourier transform infrared (FT-IR), and thermogravimetry (TG) were employed. An investigation of the impact of the material on the adsorption kinetics, thermodynamics, and ionic strength of CR was conducted. The results demonstrated that the quasi-second-order kinetic model and Langmuir isotherm were in harmony with our experimental sorption data. Additionally, thermodynamic parameters of adsorption such as enthalpy and free energy were evaluated. Nanoporous CAU-23 with excellent water stability and suitable pore size is well suited for capturing CR molecules. Importantly, through a comprehensive investigation of experimental and theoretical studies, CAU-23 forms π–π interactions and electrostatic attraction with CR molecules, characteristics that promote CAU-23 as one of the most promising adsorbents for the elimination of CR from water.

“…Recently, increasing attention has been paid to nitride coatings with multilayer architecture due to their high mechanical and tribological characteristics [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. The multilayer architecture of the obtained coatings makes it possible to influence the structural-phase state of the layers by changing the modulation period of alternating layers, and, in addition, allows for combining their individual properties [ 15 , 16 , 17 , 18 ].…”

This work is devoted to the study of the formation of nanostructured multilayer coatings (TiZr/Nb)N on the surface of an AISI 321 steel substrate depending on the deposition parameters of the Arc-PVD method. The results of the X-ray diffraction analysis showed the formation of solid solution (TiNb)N and ZrN in the multilayer coatings with an FCC structure, ε-NbN with a hexagonal structure, as well as with a small volume fraction of the ε-Ti2N and β-Nb2N phase. On the basis of phase composition data, it is possible to assume that an increase in the number of bilayers leads to a decrease in the nitrogen concentration in the bilayers and, consequently, to a decrease in the volume fraction of ε-NbN and β-Nb2N nitrides. In all investigated systems obtained at −100 V and −200 V bias potentials, ε-NbN is the main phase. The study of the element distribution over the thickness of the (TiZr/Nb)N coating confirms the results of the X-ray diffraction analysis. The use of the structure model in the form of alternating layers allows for significantly improving the adhesion characteristics of the protective coating, as well as ensuring their high hardness. Based on the experimental results, it is possible to analyze changes in the mechanical and tribological properties of multilayer coatings depending on the number of applied bilayers. The results of the study of the elastic modulus and hardness of multilayer coatings (TiZrNb)N with different numbers of bilayers showed that a large number of bilayers (small thickness of each individual layer) shows the lowest value of hardness. It is assumed that as the bilayer thickness decreases, the coating characteristics are closer to the monolayer alloy than to the multilayer structure.

“…Several technologies have been used to produce TiN coatings, including sol-gel [6], physical vapor deposition (PVD) [7], chemical vapor deposition (CVD) [8] and plasma sputtering (PS) [9]. All the above mentioned techniques have their own characteristics and therefore the quality and performance of the resulting prepared coatings differs a lot.…”

The purpose of this study was to create TiN films on 430 stainless steel by electrophoretic deposition. The microstructure of the coatings was investigated by SEM. The results of the X-ray diffraction showed that after the sintering, apart from the titanium nitride, no secondary phase was observed. Sintering at 1200 °C for 1 h reduced porosity and increased adhesion between particles. Corrosion current density and corrosion potential were obtained for the best coated sample of 6.3 μA.cm-2 and-332 mV (vs. SCE) versus 37 μA.cm-2 (decreased to one sixth) and-453 mV (vs. SCE) for bare 430 steel, respectively. Rockwell indentation test according to VDI 3198 standard and the type and volume of the fracture area was used to evaluate the interfacial adhesion of the coatings. The results showed that all coatings resist shear stress and prevent a wide range of delamination, however the 1200 °C sintered sample has more adhesion strength.
