Hackmanite is an exceptional mineral – it changes colour and glows in the dark. Research on the material started by chance at the Department of Chemistry of the University of Turku, and researchers there have been astounded by its versatility. Hackmanite’s properties have been tested in the bunkers of the Sweden’s Ministry of Defence and, within a year, the mineral will be sent to space.
Hackmanite Changes Colour Also Upon Exposure to Nuclear Radiation – Memory Trace from Radiation Enables New Applications
Researchers at the University of Turku, Finland, have long studied the colour-changing properties of the natural mineral hackmanite upon exposure to UV radiation or X-rays. Now, the research group studied the reactions of synthetic hackmanite to nuclear radiation. The researchers discovered a one-of-a-kind and novel intelligent quality, gamma exposure memory, which allows the use of hackmanite as e.g. radiation detector.
While investigating hackmanite, a natural wonder material, researchers found that it, in addition to two other minerals, can change their colour upon exposure to UV radiation repeatedly without wearing out. The results show that the inexpensive hackmanite, which is easy to synthesise, is also an excellent material because of its high durability and applicability for different purposes.
Researchers from the University of Turku Develop Hackmanite-Based Radiation Detectors for the International Space Station
Researchers from the University of Turku are developing a new hackmanite-based dosimeter and passive detectors for the International Space Station, intended to be used to measure the radiation dose uptake of materials during space flights. The year-long research project is funded by the European Space Agency, ESA.
Researchers from the University of Turku have discovered a new method of X-ray imaging based on the colouring abilities of the natural mineral hackmanite. The international group of researchers also found out how and why hackmanite changes colour upon exposure to X-rays.
Scientists at the University of Turku have discovered the origin of the glow in the natural mineral that generates white luminescence in the dark. By studying natural minerals, significant new knowledge can be gained for the development of better synthetic materials.
