The change in adhesion of glass ionomer cement (GIC) to prepared tooth dentin when the GIC was exposed to ultrasound (characteristics are 23 kHz, power level 1 and 50 % filling) during mixing has been studied. The increase in the adhesion compared to cement without ultrasound exposure was 39 %.

The The work is devoted to a comparative analysis of experimental methods for measuring residual stresses in thermally sprayed coatings, self-fluxing NiCrBSi alloys deposited by plasma and gas thermal spraying methods. The features of each method are considered, including accuracy, depth, fragility, cost, and applicability. A comparative table, an analysis of the theoretical ...

This study presents an optimization approach for the siting of electric vehicle charging stations, integrating management strategies, charging scenarios, and user behavioral characteristics. A two-stage constant-current/constant-voltage charging protocol is implemented, and charging demand is predicted using a Monte Carlo simulation framework. Considering various charger capacities, ...

The article discusses the problems associated with the disposal of polymers that make up solid household waste. It is emphasized that the crushed polymers can be used in various industries. The article presents a method for calculating the energy required for the destruction of a polymer material.

This work studies the electrical properties of nanoscale TiO₂ films obtained by anodic oxidation. Current-voltage characteristics measured in the temperature range 263–300 K show a dominant charge injection mechanism at the metal-oxide interface. The analysis confirms that the conductivity is determined by defect states rather than the intrinsic properties of the dielectric.

The paper evaluates the applicability of a mechanistic grinding force model for plasma-sprayed Al₂O₃-based ceramic coatings modified with boron and titanium oxides. Experimental validation shows high correlation (R² > 0.89), confirming the model's effectiveness in predicting forces and guiding process optimization.

The analysis of the factors affecting the efficiency of operation, as well as the scheduled preventive maintenance of cone crushers of large crushing is carried out. A method for monitoring the condition of armor plate using a 3D scanner is proposed. An innovative solution has been developed to replace individual armor plates with two solid armor rings along the lower cords of a ...

This study examines the effect of laser treatment on the surface state of plasma-sprayed Al2O3 ceramic coatings. Surface remelting is shown to significantly reduce roughness and porosity, producing a smooth and dense surface without mechanical damage.

Dendritic copper film samples obtained by electrolytic deposition on a copper substrate at a current density of 20 A*dm-2 were analyzed using image recognition. The structure of the dendritic films was studied using optical microscopy. ImageJ software was used to characterize the interdendritic space. The analysis resulted in porosity measurements and the maximum, average, and ...

A combined technology for wear-resistant composite coatings on steel parts is proposed, combining cold gas-dynamic spraying of an aluminum interlayer with boron nitride addition and subsequent micro-arc oxidation to form a ceramic layer with enhanced operational properties.
