  • "Hot" graphene reveals migration of carbon atoms

    The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material can now be determined indirectly while the materi more

  • Why gold-palladium alloys are better than palladium for hydrogen storage

    Materials that absorb hydrogen are used for hydrogen storage and purification, thus serving as clean energy carriers. The best-known hydrogen absorber, palladium (Pd), can be improved by alloying with gold (Au). New research led by The University of Tokyo Institute of Industrial Science explains for more

  • How do very small particles behave at very high temperatures?

    A Swansea University nanomaterials expert has been looking at how small gold particles survive when subjected to very high temperatures. The research is important to the engineering sector for some potential applications of nanotechnology, for example in catalysis and aerospace, where particles of o more

The Chemistry of Moisturisers

It’s the middle of summer, and hopefully, if you’re heading out in the sun, you’re taking the precaution of applying sun cream beforehand. Sometimes, however, you can end up with sunburn despite your best efforts to prevent it. After sun and moisturisers can help to soothe the burn – here, we take a more
