Application
- Supramolecular Gels Based on C(3)-Symmetric Amides: This study demonstrates the application of potassium cyanide in the development of supramolecular gels used for anion-sensing and dye removal from water. It highlights the role of potassium cyanide in enhancing the functionality of materials designed for environmental cleanup and monitoring, aligning with sustainable research practices in material science (Kuppadakkath G et al., 2024).
- Binucleate Rhizoctonia induced tomato resistance against Rhizoctonia solani: This research explores the use of potassium cyanide in studying plant-pathogen interactions, particularly focusing on enhancing tomato plant resistance against fungal diseases. The application in agricultural biotechnology demonstrates the potential of potassium cyanide in developing disease-resistant crop varieties, contributing to sustainable agriculture practices (Taheri P et al., 2024).
