This international collaboration, involving 32 institutes from across the globe, furthered understanding of the creation of heavy elements by measuring the beta-decay half-lives of 110 isotopes. The new and updated values provide vital input into theoretical models that attempt to explain the production of the heavy elements found on Earth, and further our understanding of the energy released during neutron-induced fission of uranium.

Researchers from NPL, IBM and the University of Edinburgh developed the first conceptually simple but broadly applicable model for water, based on a simplified representation of electronic and quantum mechanical effects. The method's success describing a challenging system such as water means it could be applied more generally to tackle new problems in materials science and provide insights into the molecular origin of complexity across the physical and life sciences.

Researchers at NPL, UCL, the European Synchrotron Radiation Facility and Imperial College London showed for the first time how heat-induced damage to lithium-ion batteries evolves in real-time and leads to failure. These results enhance our understanding of the most dangerous failure mechanism of such devices and the techniques developed could lead to major improvements in the design of lithium-ion batteries and their safety features.

Scientists from NPL and UCL converted a breast milk protein into an artificial virus that kills bacteria on contact. The team re-engineered a tiny fragment of the protein into a nanoscale building block, which self-assembles into virus-like capsules to effectively target bacteria. In addition, by replacing their viral genes with drugs or therapeutic genes, the virus-like capsules become effective tools in the pursuit of gene therapy to cure many diseases, from cancer to cystic fibrosis.

Carrier type inversion in quasi-free standing graphene: studies of local electronic and structural properties
Christos Melios, Vishal Panchal, Cristina Giusca and Olga Kazakova et al
Researchers from NPL, the University of Surrey and the Institute of Electronic Materials Technology cast a new light on the electronic properties of quasi-free standing graphene, a material that may find applications in high speed electronics, sensing and electronic applications. For the first time, the research showed the nanoscale changes of graphene's electronic and structural properties upon hydrogen intercalation, which decouples the material from its supporting substrate.

NPL demonstrated the highest level of agreement ever reported between two different types of femtosecond frequency combs - the tools used to measure the frequency of the next generation of atomic clocks. In preparation for any future redefinition of the second, it's crucial that we can accurately compare the frequencies of atomic clocks. This research demonstrates that femtosecond combs will make a negligible contribution to the uncertainty of such frequency measurements.
