Description

Application

• Corncob-derived biodegradable packaging films: A sustainable solution for raspberry post-harvest preservation.: This study explores the use of corncob-derived biodegradable films infused with calcium chloride dihydrate to preserve raspberries post-harvest. The films effectively reduce microbial growth and extend the shelf life of the fruit (Paudel et al., 2024).


• The Effect of a Setting Accelerator on the Physical and Mechanical Properties of a Fast-set White Portland Cement Mixed with Nano-zirconium Oxide.: The study examines the impact of calcium chloride dihydrate as a setting accelerator in cement composites, enhancing their mechanical properties and setting time, which is vital for construction applications (Chen et al., 2023).


• Co-administration of Intravenous Drugs: Rapidly Troubleshooting the Solid Form Composition of a Precipitate in a Multi-drug Mixture Using On-Site Raman Spectroscopy.: This paper highlights the use of calcium chloride dihydrate in pharmaceutical formulations to stabilize drug mixtures and prevent precipitation, ensuring the efficacy of intravenous drugs (Nilsson et al., 2023).


• Calcium chloride dihydrate supplementation at ICSI improves fertilization and pregnancy rates in patients with previous low fertilization: a retrospective paired treatment cycle study.: The research demonstrates that calcium chloride dihydrate supplementation during intracytoplasmic sperm injection (ICSI) significantly improves fertilization and pregnancy rates in patients with previous fertilization failures (Popkiss et al., 2022).
