Description

Application

• Temperature-Induced Change of Water Structure in Aqueous Solutions of Some Kosmotropic and Chaotropic Salts.: Investigates how temperature variations alter the water structure in solutions containing kosmotropic and chaotropic salts, including potassium perchlorate, to understand their impact on biochemical processes (Kunsagi-Mate S et al., 2021).


• Perchlorate detection via an invertebrate biosensor.: Discusses the development of an invertebrate biosensor for the detection of perchlorates, offering a novel approach to monitoring environmental and potentially harmful residues of potassium perchlorate (Sturzenbaum S et al., 2021).


• Towards understanding the effects of heat and humidity on ageing of a NASA standard pyrotechnic igniter.: Provides insights into the degradation processes of pyrotechnic igniters under varying environmental conditions, useful for enhancing the safety and effectiveness of devices containing potassium perchlorate (Yoh JJ et al., 2019).


• Interpreting the near infrared region of explosives.: Analyzes the near-infrared spectral characteristics of various explosives, including studies on potassium perchlorate, to improve detection and safety protocols in analytical chemistry applications (Garcia-Ruiz C et al., 2018).
