USING the apparatus already described (see NATURE, Mar. 22, vol. 125, p. 457; Rend. Ace. Lincei, vol. 11, p. 679), I was able to obtain good photograms of crystalline hydrogen iodide at about –170° C.

Recent advances in catalyst development have significantly improved the viability of the sulphur-iodine thermochemical cycle for sustainable hydrogen production. Key reactions within this cycle, ...

The emission of carbon dioxide (CO₂) is one of the primary factors contributing to air pollution and climate change on Earth.

The reaction of hydrogen peroxide with potassium iodide is demonstrated in a tall cylinder. Saturated potassium iodide is added to a mixture of soap, glycerin, water, and hydrogen peroxide. Oxygen and ...
