Mechanisms of Stone Formation [PDF]

Clinical Reviews in Bone and Mineral Metabolism, 2011
We have reviewed the general mechanisms involved in kidney stone formation, with reference to those composed of calcium oxalate or phosphate, uric acid, and cystine. These processes include nucleation of individual crystals, aggregation or secondary nucleation to produce small intrarenal multicrystalline aggregates, fixation within the kidney, and ...

Low temperature synthesis of NaSICON NaZr2(PO4)3 powders with the assistance of in situ formed mineralizer [PDF]

Processing and Application of Ceramics, 2023
A new approach was developed to prepare NaZr2(PO4)3 (NZP) powders at low temperature of 330°C. The effect of different molar ratios of ZrO(NO3)2 • xH2O to NaH2PO4 • 2H2O on the synthesis of NZP powders was systematically investigated by XRD, FE-SEM, TEM,

Mechanics of Rouleau formation

Biophysical Journal, 1981
The formation of rouleau of red blood cells is considered from the standpoint of adhesion theory. With the use of the elastic properties of the red blood cell membrane obtained from previous work, the strain energy of the red blood cell in rouleau formation has been computed. The surface energy of adhesion for the bonding of two red blood cells is then
