Hierarchical AC/Si/MXene composite anode integrates conductivity, porosity, and high capacity, ensuring stability and efficiency for next-generation lithium-ion batteries.

In this paper considered the form of an autonomous house roof for effective use of the wind kinetic energy in the application of closed wind power plant. The elements of the wind power plant and the roof of the autonomous house are transformed into a finite element model for aerodynamic calculation. In the calculations used various versions of the autonomous house roof to find the optimal conditions for increasing the energy efficiency factor of the energy carrier. The results of this work can be used in the design of autonomous houses.

This paper presents an integrated approach to improve the efficiency of a closed-type wind turbine. The influence of the confuser’s angle of attack on the wind speed in the turbine blades located area has been studied. A computational fluid dynamics (CFD) model of the installation was created using COMSOL Multiphysics software. The contours of speeds and pressures were studied at different wind speeds, as well as under different confuser parameters. Based on the results of the study, a recommendation for the optimal angle of attack of the confuser was made for constructing a closed-type wind turbine, and MXene-based nanomaterials were considered for use in icing prevention systems.

The demand for high-performance energy storage systems with enhanced energy and power density is growing alongside the renewable energy, mobile devices, and electric vehicle sectors. MXenes, a class of two-dimensional (2D) transition metal carbides, nitrides, and carbonitrides, have emerged as promising electrode materials for next-generation energy storage systems owing to their high electrical conductivity, hydrophilicity, and tunable surface chemistry. This review provides a comprehensive analysis of recent progress in MXene-based energy storage systems, focusing on MXene synthesis routes, their performance in energy storage applications, associated challenges, and future research directions. It discusses the advantages and disadvantages of various MXene synthesis routes and MXene-based composites, defect engineering, and MXene oxidation, which are crucial for energy storage applications, including rechargeable batteries and supercapacitors. The review also explores the challenges and prospects of scaling up MXenes and their composites for energy storage applications and the existing obstacles to integrating these materials into energy storage systems, with the aim of developing next-generation energy storage systems.
