  • 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

  • A super resolution view of chemical reactions

    Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have demonstrated, using a super resolution microscopic technique, how to follow chemical reactions taking place in very small volumes. The method of analysis developed by the Warsaw physicists in collaboration wi 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
