US researchers make ‘smallest’ diode from DNA molecules

Binquin Xu

Researchers at the University of Georgia and at Ben-Gurion University in Israel claim to have demonstrated how nanoscale electronic components can be made from single DNA molecules. According to the study’s lead author, Bingqian Xu, an associate professor in the UGA College of Engineering: “For 50 years, we have been able to place more and more computing power onto smaller ...

UK researchers make high temperature op amp in SiC

GetFileAttachment

Raytheon UK has collaborated with Newcastle University to produce silicon carbide (SiC) based amplifier circuitry with operational amplifier like characteristics. The research has used the thermal characteristics of SiC not in a high power device, but in small-signal circuitry that can operate in high temperatures. “To date, the focus on Silicon Carbide semiconductors has been power electronics and exploiting the ...

Glasgow researchers build “smartphone” gravity meter to measure volcanos

GetFileAttachment

Scientists at the University of Glasgow have created a very low cost gravity meter which could be used to monitor volcanic activity using commercial MEMS device technology found as accelerometers in smartphones. The result they says is a sensitive detector capable of measuring minute changes in gravity, and at significantly lower cost than a traditional gravity meter (gravimeters). They believe ...

Glasgow researchers develop inexpensive way to make radially polarised white light

glasgow

Physicists at the University of Glasgow have developed a new and inexpensive way to make radially polarised white light, which could help scientific advances in astronomy and microscopy. Dr Neal Radwell and Dr Sonja Franke-Arnold, from the University’s School of Physics and Astronomy, have discovered a new way of producing radially polarised beams, using broadband white light rather than single ...

Samsung and UK-based Codeplay address mobile GPU power

Andrew Richards, CodePlay

Samsung Electronics UK is part of a European Union-funded research project to develop a power analyst tool to make the mobile graphics processor (GPU) more power efficient. Samsung has teamed up with Edinburgh-based GPU technology company Codeplay, Greece-based silicon IP developer Think Silicon and TU Berlin to develop a tool for enabling smartphone batteries to last longer while running advanced video ...

Predictions 2016: datacentres get 100Gbit/s optical links, says Imec

13jan16imecHybrid CMOS Si photonics transceiver

If we want to make silicon photonics technology cost-effective, we have to optimize the packaging, writes Joris Van Campenhout, Imec programme director for optical I/O. Optical data transmission is a key answer to the ever growing data traffic. Today, data centres make use of hundreds of thousands optical links that interconnect the server racks at network rates up to 40Gbit/s. ...

Predictions 2016: solar cells target 30% efficiency – Imec

Jef Poortmans

We need to maximise the energy yield of our solar cells and panels, writes Jef Poortmans, scientific director for photovoltaics at Imec For solar energy in the past, achieving as low a ‘cost per watt peak’ as possible was important. Solar cells and panels were optimised to generate as much power as possible at as low a cost as possible under ideal ...

Predictions 2016: flexible chip tech gets real – Imec

13jan16imec_flexible_electronics_with_integrated_oleds

Determining what will be needed in five years’ time is a major challenge, writes Paul Heremans, technology director large-area electronics at the Imec research centre in Belgium Our task as a research center is to offer our partners technical solutions for their future applications, two to three product generations ahead in time. But when it comes to flexible electronics, the ...

Government to fund photonics research in North Wales

article

Innovate UK, the government’s technology investment organisation is to put £500,000 into the photonics and optoelectronics research cluster in North Wales. The aim is to encourage R&D projects that may be too risky for companies to take forward without any support, and where the majority of the project activities are carried out in North Wales. Funding for individual projects  will range from £50,000 to ...
