• Fuel of promise – With fuel cells touted as a possible solution to aspects of the energy crisis, the Institute of Measurement at the National Physical Laboratory (NPL), Teddington, UK, is stepping up research in an attempt to commercialise them. Scientists at NPL aim to improve the durability of cells by finding a method to directly examine the processes inside a working cell. They hope to develop a model that will describe cell functions at every level. Using thermal imaging they are investigating more efficient materials for electrodes and electrolytes.
• Materials for energy – Energy conversion is a major worldwide issue. Alan Atkinson, Director of Materials Research, and Jim Williamson, Professor of Materials Chemistry at Imperial College London, UK, describe energy materials research at the College. The article explores solid oxide fuel cells, suitable materials for use within them, and research to optimise organic solar cells and improve the efficiency of dye sensitised solar cells.
• Going platinum – Exploring the trends in platinum supply and demand, this feature examines the formation and location of the metal. The changes in demand from the automotive section are explored, as is the use of platinum in jewellery. Information is provided about major investors and their current projects.
In addition, Materials World carries industry and conference news, as well as event listings. The mining feature in July’s issue covers developments in Scottish coal. Looking at the opportunities ATH Resources’ has capitalised on, the article also considers responsible mining and how coal can help address the energy gap.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
