Histochemical techniques applied at the ultrastructural level have clearly established the periplasmic space as the site of alkaline phosphatase activity in Plectonema boryanum. Considerable enzyme activity is found after the organism is placed in a phosphate-free medium for 5 days. This activity is found only in the cellular fraction of the culture with no activity present in the culture mediu...

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...

Microporous ceramic material, based on β-tricalcium phosphate β-Ca3(PO4)2 with grain size 2–5 μm, pore smaller than 10 mm, and density 1.22 g/cm3 corresponding to ~40% of the theoretical (3.07 g/cm3) β-Ca3(PO4)2, was obtained from a powder mixture given molar ratio Ca/P = 1.5 after firing at 1100 °C. A homogenized synthetic dicalcium hydrogen phosphates 1 calcium citrate tetrahydrate Ca3(C6H5O7...
