C-seal F Magnified 200 Times (IMAGE) Rice University Caption C-seal F, a carbon source, magnified 200 times reveals its high surface area of 12.5 square meters per grams. Processing it into oxidatively modified carbon raises its surface area to 16.9 square meters per gram while enhancing its ability to remove radioactive cesium and strontium from water, according to researchers at Rice University and Kazan Federal University.
