Hackmanites & gamma radiation article makes the back cover of Materials Horizons

Our article “Reusable radiochromic hackmanite with gamma exposure memory” published in the Materials Horizons journal got a place in the journal’s back cover. Based on Mika’s idea, Sami took a picture of a pile of hackmanite on top of a glass plate, which he partially colored with UV light to achieve a difference between the non-colored and colored. Big thanks also go to Kari Loikas, whose sturdy construction light he borrowed helped create a dramatic contrast in the picture.
