Agrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.Abstract Ammonia (NH3) volatilization reduces fertilizer use efficiency and increases environmental nitrogen (N) loss when urea ammonium‐nitrate (UAN) is surface‐applied. Volatilization is driven by localized pH increases resulting from the rapid hydrolysis of large quantities of urea.

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids
Advanced Energy and Sustainability Research, Volume 6, Issue 5, May 2025.Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.
