Scientists at three Department of Energy national laboratories claim to have discovered how to keep a lithium ion battery cathode from developing a coating that degrades its performance. The teams used a manufacturing technique to form the cathode material into tiny, layered particles that store a lot of energy while protecting themselves from dama...

Last month, IBM opened a new global headquarters for its Watson Internet of Things (IoT) unit in Munich. At the launch, the company made a series of announcements – including new offerings, capabilities and partners – with the aim being to extend cognitive computing into the rapidly evolving IoT world by deploying IBM’s Watson IoT...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences and the Innovation Centre Iceland have built a polarimeter on a microchip, revolutionising the design of this widely used scientific tool.When light is reflected or scattered off an object, its polarisation changes and measuring that change reveals a lot of in...

The manufacture of high performance low power electronics devices based on graphene nanoribbons is likely to be possible, according to an international research team based at Tohoku University’s Advanced Institute of Materials Research.In its work, the team used molecular assemble to connect chiral edge graphene nanoribbons (GNRs) with zi...

Organic LEDs are attractive not only because they emit light in all observation directions, but also for their colours and high contrast. It is also possible to manufacture transparent and flexible OLEDs, enabling new applications.OLEDs consist of ultra thin layers of organic materials – the emitter – between two electrodes. When a...

A team from Northwestern University in the US claims it has made the laser simpler and more versatile by integrating a mid infrared tunable laser with an on chip amplifier. The development is said to allow an adjustable wavelength output, modulators and amplifiers to be held inside a single package.According to the team, the laser has demonstra...

Imagination Technologies has extended its Rogue graphics architecture with the addition of two GPUs. The devices, part of the PowerVR Series7XT Plus family, are said to be aimed at the premium and mid-range segments of the consumer electronics market.Peter McGuinness, director of multimedia technology marketing, said: “We’re rolling...

The Centre for Process Innovation (CPI) and Beneq have signed a long term collaboration agreement for the use of atomic layer deposition (ALD) technologies in printable electronics applications.The agreement brings together Beneq’s high precision vacuum coating alongside CPI’s capability in the scale up of printed electronics. Worki...

Researchers at ETH Zurich have used a 3D print technology called Nanodrip to create a new type of transparent electrode, which takes the form of a grid made of gold or silver ‘nanowalls’ on a glass surface.The electrode is to have a higher conductivity and to be more transparent than those made of indium tin oxide, the material curr...

A team of researchers from the University of Surrey’s Advanced Technology Institute (ATI) has grown vertically aligned carbon nanotubes (CNTs), in a grid-like formation on glass. The CNTs create wafer-thin, flat structures that could enable the miniaturisation of a range of optical devices. Removing the need for traditional curved refracting...
