Dynamic nuclear polarisation (DNP) gives large (>100-fold) signal enhancements in solid-state nuclear magnetic resonance (solid-state NMR) spectra via the transfer of spin polarisation from unpaired electrons from radicals implanted in the sample. This means that the detailed information about local molecular environment available for bulk samples from solid-state NMR spectroscopy can now be obtained for…

“Make possible the loyal execution of any honest order” Numa Droz, Member of Swiss Parliament and Federal Councillor (1877) Precious metals are subject to great scrutiny from lawmakers because of their financial and strategic importance. Gold and silver coins have been hallmarked since ancient times but the platinum group metals (pgm) were only known from…

In the 2014 review (1) discovery circumstances for 85Ru and 86Ru were referenced only in the form of a preprint but have now been reported in the open literature (2). For the most recently discovered isotopes the discovery years for both 128Rh and 90Pd are the manuscript dates of the given references whilst for 125Ru,…

The SI system of international units of measurement is constantly adapting to the latest technology and scientific discoveries.

Introduction “Surface Treatments for Biological, Chemical and Physical Applications” was written to provide an up to date overview of surface modification techniques, with a specific leaning towards applications rather than pure science. The tone of the book strikes a good balance between accessible and technical, and is targeted towards a range of audiences, from undergraduate…

On the eve of new EU regulations, and in the wake of recent large-scale data privacy breaches, a new ISO committee is leading the way with guidelines that put the consumer back in control.

The fight against climate change has unexpected allies with some of the heaviest-polluting industries joining its ranks. Why have they chosen to take a stand? And what are they doing to help clear the…

Despite the international community’s best efforts, extreme weather events and slow-onset climate change continue to wreak havoc on our lives and livelihoods. Adaptation measures, however, will help us…

One of the key challenges for the aviation industry over the coming years is how to continue delivering safe, reliable, efficient and cost-effective air travel as well as being environmentally responsible…

The United Nations Environment Programme (UNEP) asserts that ours is the last generation that can stop climate change. We need to do this by changing to a zero-carbon, sustainable, cyclic economy. Yet…
