For the spray pyrolysis approach, a custom-built setup was used, with the substrate...
Titanium-based implants are frequently used in medical practice for bone-associated injuries and disorders. However, the osteointegration of Titanium is limited by its lack of bioactivity. To overcome this drawback, in this study we functionalized titanium-based surfaces with 3D polymeric microstructures fabricated by laser direct writing via two-photon photopolymerization (LDW via TPP), which...
To obtain the baseline levels of soil radioactivity in the city of Veles and its environs, 53 topsoil samples were collected from uniformly distributed sites across an area of $1200\;\mathrm{km^2}$. Following appropriate laboratory preparation, gamma spectrometry was used to determine the activity concentrations of the radionuclides present in the soil samples. The analysis focused on the...
In the 18th and 19th centuries, fresco painting in the Balkans evolved under the influence of political shifts, religious continuity, and cultural exchange. Despite Ottoman rule, Orthodox Christian traditions remained strong, blending with local and folk elements to create a unique artistic language. These frescoes became not only religious symbols but also quiet affirmations of cultural...
