Calcium binding by chondroitin sulfate
Calcified Tissue Research, 1968The binding of calcium by chondroitin sulfate C was studied by employing biological and physicochemical methods for the quantitative determination of ionic calcium. Mean values for logKj, the logarithm of the uncorrected formation constant for a calcium-chondroitin sulfate complex, were 1.64 with the frog heart technique, 1.55 with the murexide method,

Journal of Applied Polymer Science, 1992
AbstractThe homopolymerization of acrylamide in water alone and also in the presence of calcium sulfate dihydrate and of calcium sulfate hemihydrate has been studied. Polymerizing acrylamide with the redox pair potassium persulfate—sodium bisulfite, the rate increased steadily with increasing initiator concentration.

Mixed Calcium Carbonate and Calcium Sulfate Scale
CORROSION 2016, 2016Abstract Crystallization fouling is one of the major problems in process industries using water. In the present work the precipitation of calcium carbonate (CaCO3), and of mixed calcium carbonate - calcium sulfate (CaSO4) deposits on the walls of a heated metal surface of stainless steel was investigated.

The Effect of Sulfate on Serum Ionized Calcium
American Journal of Kidney Diseases, 1983Serum sulfate concentrations may reach five to ten times normal in renal failure patients dialyzed on a sorbent cartridge system, and these patients have elevated alkaline phosphatase levels suggesting an increased incidence of renal oseodystrophy. We studied the effect of adding sulfate on ionized calcium (Ca2+) in human serum in vitro and in rat ...

Crystallization of calcium sulfate on polymeric surfaces
Journal of Colloid and Interface Science, 2011Surface crystallization of calcium sulfate dihydrate (gypsum) on a series of polymeric surfaces was studied using a quartz microbalance system. Polyelectrolyte multilayer films (positively and negatively charged surfaces) were formed on the quartz crystal microbalance (QCM) sensors utilizing a layer-by-layer spin-assembly method. The kinetics of gypsum

Structure of calcium aluminate sulfate Ca4Al6O16S
Journal of Solid State Chemistry, 1995The commensurately modulated structure of polycrystalline calcium aluminate sulfate was determined using spectroscopic and electron microscopic information and calculations with the bond-valence method. The neutron powder diffraction data were refined by the Rietveld profile technique.

Calcium sulfate: Properties and clinical applications
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2008AbstractCalcium sulfate (CS) has enjoyed a longer history of clinical use than most currently available biomaterials. It is well‐tolerated when used to fill bone defects and undergoes rapid and complete resorption without eliciting a significant inflammatory response. The raw material from which it is made is relatively inexpensive and abundant.

Regeneration of Bone in the Presence of Calcium Sulfate
Archives of Otolaryngology - Head and Neck Surgery, 1980I describe 110 patients in whom diseased and destructed bone was restored to normal healthy bone. The first ten patients were healed by using bismuth-iodoform, and the following 100 patients were treated using the hemihydrate of calcium sulfate (CaSO4.2H3O).
