Chemistry in Pictures: The flower in volcanic rock
Some polymers, inorganic salts, and volcanic rocks, called rhyolites, contain crystals with radially arranged textures. Masamichi Shiono, an engineer at Hitachi High-Technologies was intrigued by a rhyolite sample containing such an inclusion, so he sliced a section and analyzed it with one of his company’s scanning electron microscopes. One image he took reminded him of a Rosa rugosa flower, so he colorized it to produce the artwork shown. He entered the image in the Japanese Society of Microscopy’s 2017 photo contest.
