• 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.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
