Future of Film & Video event being livestreamed from Dublin’s Science Gallery July 13, 2012

As I’ve noted previously (my April 29, 2011 posting) Dublin is celebrating itself as a ‘City of Science’ this year. As part of the festivities (e.g. the Euroscience Open Forum [ESOF} meetings are now taking place in Dublin), the Future of Film & Video at the Science Gallery will be livestreamed on Friday, July 13, 2012 from 1800 to 1930 hours (10 am – 11:30 am PST), from the event page,

Join Academy award winners Anil Kokaram and Simon Robinson, and BAFTA award winner Mark Jacobs as they discuss the future of film and video, from today’s cutting-edge 3D tech, to tomorrow’s innovations being imagined in labs across the world. You’ll never look at a screen the same way as these visionaries show that in the film and video industry you should expect the unexpected.

This event is part of the UCD Imagine Science Film Festival, and is part of Dublin City of Science. We are grateful for the support of Google Dublin, the Chrome-Media Group at Google, Mountain View, the Sigmedia Group in the Engineering Dept, Trinity College Dublin and also Science Foundation Ireland.”

I’m hoping this will be focussed on something other than the future of 3D technology.

Transforming flat screens with P-type conductors at CRANN

I’m not sure about window-integrated flat screens as one of the applications for this technology breakthrough at Trinity College Dublin’s (TCD) CRANN (Centre for Research on Adaptive Nanostructures and Nanodevices). I think there’s enough signage and video being beamed at me everywhere I go but all indications are that more and more surfaces are going to become display and/or communication devices and these researchers seem to have found a way to speed that process.

From the March 21, 2012 news item on Nanowerk,

Researchers at CRANN, the Science Foundation Ireland funded nanoscience institute based in Trinity College Dublin (TCD), have discovered a new material that could transform the quality, lifespan and efficiency of flat screen computers, televisions and other devices (see paper in Applied Physics Letters: “Magnesium, nitrogen codoped Cr2O3: A p-type transparent conducting oxide”).

The research team was led by Prof Igor Shvets, a CRANN Principal Investigator who has successfully launched and sold two spin out companies from TCD and who is involved in the Spirit of Ireland energy project. A patent application protecting the new material was filed by TCD. Commenting on the research, Prof Igor Shvets said, “This is an exciting development with a range of applications and we are hopeful this initial research will attract commercial interest in order to explore its industrial use. The new material could lead to innovations such as window-integrated flat screens and to increase the efficiency of certain solar cells, thus significantly impacting on the take-up of solar cells, which can help us to reduce carbon emissions.” [emphasis mine]

The application for solar cells sounds a lot more appealing to me. CRANN issued a March 21, 2012 press release which included some technical details,

Devices that the new material could be used with such as solar cells, flat screen TVs, computer monitors, LEDs all utilise materials that can conduct electricity and at the same time are see-through.  These devices currently use transparent conducting oxides, which are a good compromise between electrical conductivity and optical transparency. They all have one fundamental limitation: they all conduct electricity through the movement of electrons. [emphasis mine] Such materials are referred to as n-type transparent conducting oxides. Electricity can also be conducted through as p-type materials.  Modern day electronics make use of n-type and p-type materials.  The lack of good quality p-type transparent conducting oxides, however, led the research team to develop a new material – a p-type transparent conducting oxide.

I wish I better understood the fundamental limitation of an n-type transparent conducting oxide and how the new p-type transparent conducting oxide addresses that limitation.

After reading the description of p-type materials, it seems to me that electrons also move in that material. From the Wikipedia essay on p-type materials,

The dopant atom accepts an electron, causing the loss of half of one bond from the neighboring atom and resulting in the formation of a “hole”. Each hole is associated with a nearby negatively charged dopant ion, and the semiconductor remains electrically neutral as a whole. However, once each hole has wandered away into the lattice, one proton in the atom at the hole’s location will be “exposed” and no longer cancelled by an electron. [emphasis mine] This atom will have 3 electrons and 1 hole surrounding a particular nucleus with 4 protons. For this reason a hole behaves as a positive charge. When a sufficiently large number of acceptor atoms are added, the holes greatly outnumber thermal excited electrons. Thus, holes are the majority carriers, while electrons become minority carriers in p-type materials.

Well, I am interpreting the “wandering away” bit as a type of movement so I find the descriptions just a bit confusing. As for the holes being the majority carrier in p-type materials, perhaps the electrons in the n-type materials are the majority carriers?

If there’s anyone out there who could help lift the veil of confusion, I would much appreciate it.

For those who don’t need as much handholding as I do, you can find out more about Shvets and his work here.

Pretty nanopicture from Ireland

'The Hive', taken by Dr David McGovern at Trinity's Nanoscience Institute, CRANN.

The Hive was named the Research Image of the Year for 2011 by the Science Foundation of Ireland (SFI). From the Nov. 22, 2011 news item on Nanowerk,

The SFI Research Image competition offers SFI-funded researchers the opportunity to submit digital images created during the course of their research. The winning image was taken by Dr. David McGovern under supervision by Professor John Boland, CRANN’s [Center for Research on Adaptive Nanostructures and Nanodevices] Director and Principal Investigator from TCD’s [Trinity College of Dublin] School of Chemistry.

The image is of a porous surface of the polymer polylactic-co-glycolic acid (PLGA).  From the Nov. 18,  2011 news release on the Trinity College website,

Porous polymers have the potential to deliver new biocompatible nanodevices or nanotemplates for medical applications and are of significance not only in the biomedical industry but also for materials science.  CRANN’s research on porous polymers, during which the image was taken, has the potential to enable a wide variety of applications including therapeutic devices such as in implants, sutures, prosthetic devices and for drug delivery and wound care.

The image was produced using the Zeiss Auriga Focused Ion Beam (FIB) in CRANN’s Advanced Microscopy Laboratory (AML). The Auriga FIB is the only system in Europe and has the narrowest beam width of any such instrument on the market, enabling image resolution of less than 3 nanometres, approximately 30,000 times smaller than the width of one human hair.

Congratulations Dr. McGovern.

Irish nanoscience goes to school

The ‘Nano in My Life’ educational package for students in the senior or transitional year (TY) was launched today, Nov. 17, 2011, by Trinity College Dublin’s CRANN ( Centre for Research on Adaptive Nanostructures and Nanodevices). From the Nov. 17, 2011 news  item on Nanowerk,

The ‘Nano in My Life’ package, for the first time, will bring nanoscience – an area of research at which Ireland excels and which is a key enabler for innovation and economic growth – to the Irish classroom. It will encourage students to relate science subjects to innovative careers, with exciting and challenging applications. There are seven modules, each using a range of teaching and learning approaches, including video captured at CRANN, designed to engage students and encourage active learning.

Approximately 10% of Irish exports (€15 billion) are enabled by nanotechnology with tens of thousands of jobs in the ICT [Information and Communication Technology] and medical devices sectors dependent upon this research. Ireland is ranked 6th in the world for nanoscience research and 8th for materials science research (a branch of nanoscience), with CRANN enabling the majority of this research. Earlier in the week, Prof Jonathan Coleman, Principal Investigator at CRANN and Trinity College Dublin’s School of Physics was announced as the ‘Science Foundation Ireland Researcher of the Year’ for 2011.

Commenting on the launch, Mary Colclough, CRANN’s Communications and Outreach Manager said, “There is a real need to introduce secondary school students to cutting-edge nanoscience research which is driving innovation, providing jobs for highly skilled graduates and is now forming an important part of studying science at third level. CRANN is at the cutting edge of nanoscience research, which has the potential to revolutionise a number of industries, so we feel it is important to open students’ eyes to the opportunities that will be available in the future and hopefully inspire the next Steve Jobs or Mark Zuckerberg.”

Teachers are being encouraged to apply for a package by contacting  nanoinmylife@tcd.ie. BTW, I was not aware of highly ranked Irish nanoscience research has become. Bravo!

There is also a Trinity College Dublin (TCD) YouTube channel which features a number Nano in My Life videos including this one,

I wonder when we’re going to see similar science education initiatives in Canada.
