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 ).
