Printing silicon in South Africa - Part one
printedelectronicsworld.com August 24th, 2009 The engine of the new printed electronics will be printed transistors on flexible substrates that can be one tenth to one hundredth of the cost of those in simple silicon chips. Most of the work has been directed towards organic transistors because they are easy to print and some believe that they are a good route to ambipolar transistors (p and n type in one device) and light emitting transistors. However, tussling for the low cost slot - the main market need - we now have a rapidly increasing numbers of research centers working on inorganic printed transistors, both printed silicon and printed metal oxides, particularly based on zinc oxide semiconductors. These exhibit greater charge mobility in the semiconductor and therefore higher frequency of operation opening up larger potential markets. Some say they also offer lower material costs, particularly if low temperature processes can be employed. Printed silicon nanoparticles have received the least attention because the inks are very difficult to make and often high temperature annealing is needed after the deposition. In the USA, companies such as Kovio and Nanogram have pioneered printed silicon transistors and Epson and others in Japan have done work. Now some very interesting advances are being reported in South Africa, the scientific papers including one reporting collaboration with the US company Printovate. Daniel Gamota is co-founder, with former Motorola colleague J.Zhang, and president of Printovate, Inc. which developed a clean-tech large area electronics manufacturing technology, for point-of-care diagnostics, lighting, and renewable energy applications.

Is quantum mechanics messing with your memory?
guardian.co.uk August 27th, 2009 Imagine if a cold cup of coffee spontaneously heated up as you watched. Or a cracked pane of glass suddenly un-broke. According to physicist Lorenzo Maccone at the Massachusetts Institute of Technology, you see things like this all the time - you just don't remember. In a paper published last week in Physical Review Letters, he attempts to provide a solution to what has been called the mystery of "the arrow-of-time". Briefly, the problem is that while our laws of physics are all symmetrical or "time-reversal invariant" - they apply equally well if time runs forwards or backwards - most of the everyday phenomena we observe, like the cooling of hot coffee, are not. They never seem to happen in reverse.

Folded nanoboxes could open door to nano-circuits
newscientist.com August 27th, 2009 Do you remember as a child producing paper cubes by folding up a flat cross shape? Now two researchers have applied the same technique to the nanoscale, in the process creating the first nanoparticles with precisely patterned surfaces. These patterns could form the basis of electronic nano-circuits or provide docking stations on targeted drug-delivery particles. "At the macroscale, everything can easily be patterned in three dimensions," lead researcher David Gracias at Johns Hopkins University (JHU) in Baltimore, Maryland, told New Scientist. "However, nanoparticles with precisely patterned 3D surfaces simply do not exist."

Hectic start for French university foundations

Nanotech will make furnaces cheaper, greener: developer
edmontonjournal.com August 28th, 2009 Steve Petrone works with particles less than a thousandth of a millimetre in diameter to make giant petrochemical furnaces more efficient. The revolutionary nanotechnology-based coatings created at Quantiam Technologies can significantly reduce energy and maintenance costs at plants producing olefins--the largest group of worldwide petrochemicals. And the bonus is that this also reduces greenhouse gas emissions. After eight years and $17 million taking it from the lab through pilot projects at plants such as Nova Chemicals' Joffre operation, Quantiam is ready to build a$9.2-million, 35,000-square-foot manufacturing plant in Edmonton. "Now we are ready to make the big jump from a 15-employee company to providing a significant number of high-value jobs in Edmonton. And we expect to double capacity in two years," Petrone says.
