Synthesis of the precursors, using research grade materials and locally available facilities, is optimized in order to obtain a suitable sol for BaTiO3. The optimally synthesized BaTiO3 sol is then spun onto Cu substrates to obtain films of thickness ~0.5 μm. The deposited BaTiO3 films are...

Too much nitrogen (N) in surface water is harmful to aquatic life. Subsurface drains, some along with surface inlets, are commonly used for drainage of agricultural land in humid regions and contribute unknown N amounts to surface water. Quantification of relative amounts moving through...
