Explosive Sensing Interviews
13th December 2011
Ifor Samuel has been interviewed by AIP Advances about our work on explosive sensing which has recently been published by the journal. A podcast of the full interview is available from the AIP Advances Feature Page. Graham Turnbull was also interviewed about the work and his comments appear in this month's Laser Focus World.
SPIE Lecture
2nd November 2011
Ifor Samuel delivered a plenary lecture at SPIE 2011 Optics + Photonics Solar and OLEDs in San Diego in August entitled "Emerging Applications of Organic Optoelectronics". In the talk two aspects of our work were covered - organic lasers for explosive detection and the use of OLEDs in the treatment of skin cancer. The lecture is available to watch on the SPIE website.
Rank Prize Win
20th September 2011
Yue Wang recently attended the Rank Prize symposium on optoelectronics. Presenting her recent results on organic lasers and their use as explosive sensors, Yue's excellent work was recognised with the awarding of the best abstract and presentation prize in the young scientist category. Congratulations to Yue.
Explosive Detection Work Highlighted
19th August 2011
Our work on explosive sensing has again attracted the attention of news organisations. Our recently published paper in AIP Advances, entitled "Ultra-portable explosives sensor based on a CMOS florescence lifetime analysis micro-system" has been promoted by AIP as a news highlight. The work has subsequently been featured on ScienceDaily amongst other news websites. The paper describes methods to detect trace explosive vapours by measuring the light emitted from a polymer with a compact piece of portable equipment.
Organic Semiconductor Centre Welcomes Leading Solar Cell Researchers
28th March 2011
The Organic Semiconductor Centre is this week involved in the SU2P Symposium that is being organised here in St Andrews. A collaboration between leading Scottish and US institutions, SU2P helps to deliver a disruptive new approach to business engagement and photonics research. A full session has been organised on photovoltaic research and applications, chaired by Prof. Samuel.
New International Energy Collaborations
18th March 2011
The OSC is beginning two new international collaborations in the field of organic solar cells. In the first we will team up with Dr Graeme Cooke at the University of Glasgow and Prof. Vince Rotello at the University of Massachusetts Amherst, investigating novel chemical systems for organic solar cells. In the second we will work with Prof. Joachim Loos at the University of Glasgow and Prof. Xiaoniu Yang of the Changchun Institute of Applied Chemistry (CIAC) at the Chinese Academy of Sciences, and will investigate the ageing behaviour of organic solar cells.
National Science Week
13th March 2011
On Saturday the OSC, as part of an active series of public outreach activities, took part in the Science Discovery Day in the Physics department here in St Andrews. Forming a major component of the Fife Science Festival this event attracted over 500 visitors, ranging from under 8 months to over 80 years, who came to the physics department to partake in a series of hands-on science experiments and activities. We hosted a hugely popular workshop on making Dye Sensitized Gratzel solar cells using tea and turmeric as the active medium. In addition we ran a series of hands-on demonstrations on organic fluorescence, OLED devices and optical illusions. By the end of the day future scientists between the ages of 5 and 15 had put together dozens of solar cells and a non-stop stream of enthusiastic visitors had experienced directly the type of research carried out by our group and had new knowledge of the benefits and advantages of a range of cutting edge organic optoelectronic technologies.
Paper Makes Top 20 List
23rd February 2011
One of our papers, "Effect of metal cathode reflectance on the exciton-dissociation efficiency in heterojunction organic solar cells", has made the top 20 download list for 2010 in Applied Physics Letters. This work (doi:10.1063/1.3098472) is also available as a pdf here on our group website.
