Application
- The effect of casing and gypsum on the yield and psychoactive tryptamine content of Psilocybe cubensis (Earle) Singer.: This research investigates the impact of calcium sulfate dihydrate on the cultivation of Psilocybe cubensis mushrooms. The study highlights the role of gypsum in enhancing yield and the content of psychoactive compounds, which is important for pharmaceutical applications (Foster et al., 2024).
- Gypsum-Related Impact on Antibiotic-Loaded Composite Based on Highly Porous Hydroxyapatite-Advantages and Disadvantages.: The study examines the effects of calcium sulfate dihydrate on antibiotic-loaded composites. These composites are crucial for bone regeneration and infection control, providing insights into the advantages and limitations of gypsum in medical applications (Zalewska et al., 2023).
- Organic solvent-free synthesis of calcium sulfate hemihydrate at room temperature.: This paper presents an innovative method for synthesizing calcium sulfate hemihydrate using calcium sulfate dihydrate without organic solvents. The research contributes to greener synthesis methods and sustainable material production (Reigl et al., 2024).
General description
Calcium sulfate dihydrate, also known as gypsum, is a hydrated form of calcium sulfate. It is used as a thermal insulator because of its low thermal conductivity.
