Global energy consumption is tricky to forecast. Worldwide demand is expected to top 660 quadrillion Btu by 2050, an increase of around 15% from 2021–but how much of that will derive from fossil fuels versus renewable energy sources? The World Energy Outlook estimates that as much as 66% of current energy demands are met by …

This blog post will look at the specific applications of gold nanoparticle coatings and the benefits they provide. The …
Surface enhanced Raman spectroscopy (SERS) and generic Raman spectroscopy are often discussed in tandem as they share many similarities. However, SERS diverges from conventional Raman imaging in various ways, making each technique applicable in different scenarios. We discussed the working principles of SERS in our previous article How Does Surface Enhanced Raman Spectroscopy Work? This …
Sputter coating and many other deposition techniques, including PVD, have become essential tools in the research scientist’s arsenal. Modern sputter deposition systems are practically unrecognisable from their earliest counterparts, with vacuum chambers and sputtering systems now operable on the benchtop. There is often a concern that championing ease-of-usability and compactness will lead to compromises on …
