Welcome to Neutronsources.org

Neutrons are produced at large research infrastructures. Researchers use them to look inside materials. With neutrons one can e.g. look inside a car engine, investigate drug delivery, see how plants uptake water, get insights into the development of superconductors.

This website aims to provide information about neutron facilities and neutron research worldwide. Get to know:

  • Neutrons allow analysis of polymer gels’ unusual attributes
    12.06.2019ORNL, USANeutrons allow analysis of polymer gels’ unusual attributes

    Neutrons are good probes of materials like polymer gels, largely because of their sensitivity to hydrogen and its isotope, deuterium. Using a unique technique known as contrast matching, researchers replaced some of the hydrogen …

  • Iron selenide revealed as ‘garden-variety iron-based superconductor’
    05.06.2019MLZ, GermanyIron selenide revealed as ‘garden-variety iron-based superconductor’

    Graduate student Tong Chen spent weeks creating samples to test in neutron scattering beams. About 20 to 30 1-millimeter squares of iron selenide had to be aligned and glued in place atop each crystal of barium iron arsenide.

  • Unexpected observation of ice at low temperature, high pressure questions ice, water theory
    03.06.2019ORNL, USAUnexpected observation of ice at low temperature, high pressure questions ice, water theory

    An ORNL-led team’s observation of certain crystalline ice phases challenges accepted theories about super-cooled water and non-crystalline ice. Their findings, reported in the journal Nature, will also lead to better …

    Superconductor with a twist

    American, Chinese and German scientists have found tiny distortions among the otherwise symmetrical atomic order of an iron pnictide superconductor with measurements at the triple axes spectrometer TRISP. They have thus come closer to superconductivity at higher temperatures.

    Exploring water-splitting photocatalysts with neutrons

    Solar hydrogen can be produced from water and light in a process called photocatalytic water-splitting and could help to mitigate the impact of climate change, as no fossil fuels are used in its production. It then can be used as a renewable, environmentally friendly energy carrier, such as in hydrogen fuel cells. Nonetheless, it has proved a major scientific challenge to scale-up photocatalytic water-splitting to a stage where it could viably be used to produce hydrogen in enough quantities to revolutionise clean energy.
