Conventional lithium ion batteries work by storing charge through redox changes involving cations. However the storage capacity is limited by the redox capacity of tradition metal ions in the cathode. Newer lithium-rich cathodes on the other hand are able to exceed this limit, leading researchers to believe that the anion must be playing a role. However, the mechanism of behavio had yet to be experimentally verified.

X-ray spectroscopy techniques at Diamond have given scientists a new insight into the behaviour of uranium during deep disposal of radioactive waste. Many countries will use geological disposal facilities as the final way to dispose of radioactive wastes and so it is important to be able to predict the behaviour and potential impacts of uranium under alkaline conditions relevant to deep disposal. The effectiveness of iron (oxyhydr)oxides to reduce the mobility of uranium is well known due to ...

The coupled magnetic and electronic properties of rare-earth doped GaN semiconductors have attracted a lot of interest by researchers from industry and academia in recent years. Researchers from University of Strathclyde, Osaka University (Japan) and Diamond Light Source have investigated Eu-doped GaN at Diamond beamlines B18 and I06. Their results have been published in Nature’s Scientific Reports.

The properties of nanocrystalline materials, where crystallinity is limited to particles of a few nanometres in dimension, are heavily researched in a number of contemporary areas. This is because once the crystal is reduced to such a small size, the properties may change dramatically from the bulk material. The structure of the surface atomic arrangement also becomes a significant proportion of the total structure, which may change the reactivity of the material in a nanocrystalline form. ...

The impressive appearance of the second largest Gothic cathedral in Northern Europe, York Minster, has dominated the townscape since medieval times (Figure 1). Representing the architectural expression of developing Christianity during that period, its international historical significance is unquestioned, and the Minster has provided a source of inspiration for scholars through the ages. However, recent centuries have seen conservationists battling to preserve the authenticity of this ...

Scientists at the University of Oxford and Diamond Light Source have described a new chemical catalyst for producing methanol, a promising future biofuel. By reducing the energy needed to convert biomass to methanol, the new catalyst offers a more sustainable way to make the useful chemical and fuel.
At present, methanol is used primarily in industrial chemistry, including the manufacture of plastics and synthetic fibres, and as a fuel in fuel cells. It is manufactured from natural gas, ...

In October 2010, a dam failure at an aluminium producing plant in western Hungary released around one million cubic metres of toxic red sludge into nearby towns and villages and across agricultural land. The sludge was a mixture of water and mining waste containing heavy metals and was deemed a threat to the environment by Hungarian officials. A large cleanup operation ensued. A team from the University of Leeds has used Diamond’s Microfocus Spectroscopy beamline, I18, to study samples of ...
