Two quantum photoconductivity in potassium iodide
Photoconductivity associated with two quantum absorption processes have been observed in uncolored crystals of KI. A Q-switched ruby laser and a KDP harmonic generator were used to produce light pulses whose quantum energy is more than half the band gap energy. The phbtbresponse in KI depends upon …

Anodic dissolution of zinc in potassium iodide-potassium iodate solutions
"The anodic dissolution of Zn was studied in KI-KIO₃ solutions at 25ºC. In I⁻ solutions, it was found that the apparent valence of Zn ions going into solution is approximately two. Smaller values are obtained in IO₃⁻ solutions, with the most pronounced changes occurring in the higher …

Cultivation of Palmaria palmata: spore release, vegetative propagation and decontamination techniques.
… of meristematic tissue was unsuccessful however, potassium iodide was identified as a potential decontamination treatment as it did not have a negative effect on the P. palmata tissue whereas sodium hypochlorite and methanol decreased the survival of the samples. In the flask cultures, Von Stosch …

Primary Coronal Caries Prevention with Silver Diamine Fluoride – Investigations into Efficacy and Mode of Action
… use of SDF (or SDF followed by application of potassium iodide[KI] to mitigate staining) as anti-caries agents on sound enamel and early enamel carious lesions. In this dissertation, I studied the mechanism behind SDF’s ability to prevent coronal caries which has not been studied yet. In the …

Immunological Characterization of Membrane Skeletal Proteins in "Tetrahymena pyriformis" GL
… along its surface. Low salt extraction of Triton-potassium iodide (TKI) cortical residues is an efficient means by which three membrane skeletal proteins (band A (235 kDa), band C (125 kDa), and a 23 kDa protein) can be isolated. Previous immunofluorescence studies have localized bands A and C in …
