Citrate ion possesses the right structure to be strongly bound on specific crystal faces of gypsum, CaSO4·2H2O, which results in an increase induction time precipitation, and changes morphology solid. The inhibition precipitation kinetics stoichiometric reaction Na2SO4 CaCl2 was investigated aqueous solutions with high supersaturation (0.1 M initial reactant concentrations). found longest when ...

This study aimed to investigate the effect of combining an innovative bioceramic α-calcium sulfate hemihydrate (α-CSH, CaSO4⋅0.5H2O) bone graft and platelet-rich plasma (PRP) accelerate healing regeneration in a rabbit model. The material was implanted bilaterally on rabbit’s artificially maxillary sinus defects: right received α-CSH, while α-CSH combine with PRP (α-CSH/PRP) grafted left site. ...

Based on a “filter press backwash–chemical precipitation–gaseous membrane absorption” process, treatment of harmless cyanide tailings was conducted using from gold smelting enterprises (Yunnan Province, China) as the research object. The effects air-drying time, backwash water parameters, initial pH acidification, NaHS dosage, cyanide-containing flow rate, and gaseous stages process were invest...

In this study, crystallization phenomena were investigated by real-time in situ observation of seeded droplets under evaporation using a self-developed hot-stage platform. Ternary solutions at eutonic conditions 25 °C for the following systems: NaCl–KCl–H2O, NaCl–CaSO4–H2O, and NaCl–Na2SO4–H2O. Evidence epitaxial growth was found aqueous NaCl–KCl NaCl–Na2SO4. Sodium chloride nucleated grew epit...
