Preparation of Uniform Needle-Like Aragonite Particles by Homogeneous Precipitation

Pengaruh Fortifikasi Nanopartikel Kalsium Laktat Kerabang Telur Terhadap Sifat Kimia Dan Fisik Bakso Ayam

“…Kalsium laktat paling banyak digunakan sebagai fortifikasi kalsium dengan tingkat absorpsi tinggi untuk industri pangan dan obat-obatan (Wang et al, 1999) yang diakui aman dan digunakan sebagai agen penguat, penambah rasa, pengasam, suplemen, pengental (Code of Federal Regulations, Food and Drug Administration, 1997), bahan penstabil (Amu et al, 2005),agen antibakteri (Shelef dan Potluri, 1995). Sebagai bahan pembuatan biomaterial substitusi tulang (Nurlela et al, 2013) serta sebagai agen antitartar pada pasta gigi (Chemaly et al, 1999).…”

Effect of Carbonic Anhydrase on CaCO3 Crystallization in Alkaline Solution

“…Moreover, the production of valuable products from CO 2 , such as nanosized calcium carbonate (CaCO 3 ), 6 which is extensively used as filling material or pigment in paper, paints, and plastics industries, could make the sequestration process economically feasible. 7,8 However, the hydration of the CO 2 is the slowest step. 9 Attempts have been made to enhance the hydration of CO 2 in the presence of a biocatalyst, carbonic anhydrase (CA).…”

Synthesis of Calcium Carbonate Particles in Octylamine/Water Bilayer Systems

“…The growth of CaCO 3 crystals was intertwinedly determined by solution pH, reactant concentration, and impurity ions at ambient conditions. This effort was extended by Wang et al (1999) in the precipitation of Ca ions with urea at 90°C, and by Jung et al (2000) for calcium carbonate formed in a Couette-Taylor reactor. A theoretical understanding of the crystallization habit of precipitated CaCO 3 was carried out by de Leeuw and Parker (1998) using atomistic simulation, which indicated the surface and hydration energy may directly control the formation of favored crystal structures.…”
