Modeling the Geometry and Filter Composite of the Air Cleaner.

Air pollution is currently the most significant environmental factor posing a threat to the health and lives of European residents. It is a key cause of poor health, particularly respiratory and cardiovascular diseases. The primary aim of the study was to numerically determine the impact of the air purifier model's geometry on the distribution of air within a room and to conduct experimental tests on the filtration efficiency and preliminary antibacterial activity of filtration composites.

Investigation of Energy Absorbed by Composite Panels with Honeycomb Aluminum Alloy Core.

The aim of this study was to measure the energy absorbed by composite panels with carbon fiber-reinforced polymer (CFRP) skins and a 5052 aluminum alloy honeycomb core and to compare it to previous research and isotropic material-two 25 × 1.75 mm 1.0562 alloy steel tubes.
