Researchers at the University of Electro-Communications in Tokyo, have reported the ability to supply 60W power over a 300m optical fibre system - demonstrating the potential of optical feed systems using double-clad fibres for future small cell mobile communications.

Researchers in Japan have revealed that the selective electrodeposition of tin oxide on platinum alloy nanoparticles provides an effective and robust catalyst for Polymer Electrolyte Fuel Cells (PEFCs). These fuel cells could provide an alternative to traditional fossil fuel power, but higher performance and durability under harsh conditions are needed before PEFC vehicles can be considered commercially viable.
