Possibility of application of the living tissues electric welding technologies in the treatment of varicose disease of lower extremities, using endovenous electric welding (EVEW) of large subcutaneous vein (LSV), was studied, its optimal parameters were determined. ЕVEW have provided effective impact on venous vessel, and guaranteed secure obliteration of LSV. The method may be used successfully in the treatment of varicose disease. Optimal parameters of EVEW, secure and safe in clinical conditions, were determined in experiment. Absence of negative impact of EVEW towards adjacent tissues have permitted to perform intervention without tumescent anesthesia. Further improvement and introduction of the EVEW method opens new possibilities for enhancing of quality of the varicose disease surgical treatment.

Seaborn trade has a share of about 80 % in global supply chains and is responsible for approximately 10 % of global carbon emissions. This is why the environmental impact of ships and the shipbuilding process matter. Despite that, this topic is addressed rather sparsely in the present literature body.

This paper estimates friction stir welded joints' ultimate tensile strength (UTS) and hardness using six supervised machine learning models (viz., linear regression, support vector regression, decision tree regression, random forest regression, K-nearest neighbour, and artificial neural network). Tool traverse speed, tool rotational speed, pin diameter, shoulder diameter, tool offset, and tool tilt are the six input parameters in the 200 datasets for training and testing the models.

Most previously reported susceptors for microwave welding are in powder form. In this study, a thin-film susceptor was employed due to its uniform heating rate and ease of handling. Silicon carbide nanowhisker (SiCNW) were incorporated into a poly(methyl methacrylate) (PMMA) matrix to create a nanocomposite thin film, which served as the susceptor.

Multifunctional materials are accelerating the development of soft electronics with integrated capabilities including wearable physical sensing, efficient thermal management, and high-performance electromagnetic interference shielding. With outstanding mechanical, thermal, and electrical properties, nanocarbon materials offer ample opportunities for designing multifunctional devices with broad applications. Surface and interfacial engineering have emerged as an effective approach to modulate interconnected structures, which may have tunable and synergistic effects for the precise control over mechanical, transport, and electromagnetic properties.

Galvanized high-strength steel has emerged as a key focus in automotive lightweighting research. During resistance spot welding of galvanized steel, the phenomenon of liquid metal embrittlement (LME) can occur, which is characterized by the appearance of irregular cracks on the weld spot surface. However, the impact of LME cracks on the mechanical properties of joints remains unclear.
