Wearing face masks during pandemics is an important protective measure against the spreading of virus-related infectious diseases. Nevertheless, risk indirect transmission virus by handling one earliest concerns. This problem can be minimized supplementing masks’ textile structure with coatings. Therefore, in this concept, suitable techniques for manufacturing filter media should evaluated. In ...

The paper proposes a mathematical simulation method for identifying thermophysical properties using developed software package based on composite material model presented as combination of plates alternating heterogeneous components, fiber and air, oriented parallel perpendicular to the heat flux. effect orientation angle fibers their volume content effective thermal conductivity has been deter...

To date, reinforcement concrete is the main construction material worldwide. As concentration of atmospheric CO2 steadily increasing, carbonation becomes a pressing concern. In this study, novel surface protective materials (SPMs) modified with hybrid nanoSiO2 (HNS), fly ash, and slag were developed to reduce emissions extend service life concrete. The depths measured by phenolphthalein reflect...
