The aim of this study was to investigate the sol gel synthesis of HA/FA nanoparticles and the possible formation of TCP phase or unstoichiometric calcium deficient hydroxyapatite (CDHA) from the precursors with a Ca/P ratio of 1.62. In order to prepare the sol, the solutions of Triethyl phosphite, ammonium fluoride and calcium nitrate in ethanol were used respectively as P, F and Ca precursors....

Green mature fruits of mango cv. SS-1 (Kala Chaunsa) were immersed for 10 minutes in 2.5, 5.0 or 7.5% calcium chloride (CaCl2.2H2O), calcium sulphate (CaSO4.2H2O) or calcium ammonium nitrate {Ca(NH4NO3)2} solutions. A control was also included in which fruits were dipped in fresh water for 10 minutes. The fruits were ripened at ambient temperature (25 ± 3 C) in boxes lined and covered with news...
