Phase separation phenomena during the formation of asymmetric membranes [PDF]

, 1977
The formation of membranes from two systems has been studied. In the system polyurethane-dimethylformamide-water, the mechanism for the formation of the sponge-like structure proves to be a liquid-liquid phase separation with nucleation and growth of the

Review on identification and prevention and control technology of spontaneous combustion risk area in goaf

Meikuang Anquan, 2023
The spontaneous combustion of residual coal in goaf has always been the focus of coal mine fire prevention and control work. Mastering the distribution law of coal spontaneous combustion risk area is the key to take prevention and control measures. Based

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

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,

The role of phosphorylation and dephosphorylation of shell matrix proteins in shell formation : an in vivo and in vitro study [PDF]

, 2018
Protein phosphorylation is a fundamental mechanism regulating many aspects of cellular processes. Shell matrix proteins (SMPs) control crystal nucleation, polymorphism, morphology, and organization of calcium carbonate crystallites during shell formation.
