Supplemental dietary magnesium utilizing biorelevant chelate ligands is a proven method for counteracting hypomagnesemia. In the terephthalic acid-N,N-dimethylformamide system a repulsive interaction exists between solute and solvent, which leads to an endothermic effect during dissolution. MgO-D exhibited a high removal capacity in a wide pH range of 3-9 with the maximum removal capacity of 160.94 mg g−1 for phosphate and 77.05 mg g−1 for ammonium at initial pH of 7, adsorbent dosage of 0.3 g−1. However, the coordination chemistry of such bio-relevant magnesium complexes is yet to be extensively explored or elucidated. Finally, to demonstrate the practical applicability of aligned structures of nanoparticles, 1D-like structured ZrO2@SiO2 was synthesized and incorporated inside a polymeric resin as a filler. The experimental solubility data were correlated with the modified Apelblat equation. Because of its high solubility, citric acid is preferred in its anhydrous crystal form by the food industry, where it is widely used to add acidity to products. By virtue of the tuning of the effective refractive index by varying the relative fractions of the ZrO2 core and the SiO2 shell, the optical transparency of filler-incorporated polyethersulfone composite films was retained even including 3 wt% amount of ZrO2@SiO2. It was observed that adding ethanol in the water increased citric acid solubility in all cases.
