#New research points to graphene as a flexible low-cost touchscreen solution New research published today in the journal Advanced Functional Materials suggests that graphene-treated nanowires could soon replace current touchscreen technology
and allowing for more affordable flexible displays. The majority of today's touchscreen devices such as tablets and smartphones are made using indium tin oxide (ITO)
which is both expensive and inflexible. Researchers from the University of Surrey and AMBER the materials science centre based at Trinity college Dublin have demonstrated now how graphene-treated nanowires can be used to produce flexible touchscreens at a fraction of the current cost.
Using a simple scalable and inexpensive method the researchers produced hybrid electrodes the building blocks of touchscreen technology from silver nanowires and graphene.
Dr Alan Dalton from the University of Surrey said The growing market in devices such as wearable technology
and bendable smart displays poses a challenge to manufacturers. They want to offer consumers flexible touchscreen technology but at an affordable and realistic price.
At the moment this market is limited severely in the materials to hand which are both very expensive to make
Lead author Dr Izabela Jurewicz from the University of Surrey commented Our work has cut the amount of expensive nanowires required to build such touchscreens by more than fifty times as well as simplifying the production process.
Co-author Professor Jonathan Coleman AMBER added This is a real alternative to ITO displays and could replace existing touchscreen technologies in electronic devices.
Even though this material is cheaper and easier to produce it does not compromise on performance.

#First graphene-based flexible display produced A flexible display incorporating graphene in its pixels'electronics has been demonstrated successfully by the Cambridge Graphene Centre and Plastic Logic,
with the transistor and display processing steps that Plastic Logic has developed already for flexible electronics.
The new prototype is an active matrix electrophoretic display, similar to the screens used in today's e readers,
except it is made of flexible plastic instead of Glass in contrast to conventional displays, the pixel electronics,
or backplane, of this display includes a solution-processed graphene electrode, which replaces the sputtered metal electrode layer within Plastic Logic's conventional devices,
bringing product and process benefits. Graphene is more flexible than conventional ceramic alternatives like indium-tin oxide (ITO) and more transparent than metal films.
For this prototype, the backplane was combined with an electrophoretic imaging film to create an ultra-low power and durable display.
"We are happy to see our collaboration with Plastic Logic resulting in the first graphene-based electrophoretic display exploiting graphene in its pixels'electronics,
This will target the realisation of an advanced, full colour, OELD based display within the next 12 months h

The long lifetime of these energetic holes facilitates an alternative relaxation mechanism via collisions with core-localized valence band electron
Qianglu Lin a CASP student working on the synthesis of these materials said A striking feature of the thick-shell Pbse/Cdse quantum dots is fairly bright visible emission from the shell observed simultaneously with the infrared emission from the core.
which underlies the observed enhancement of carrier multiplication likely relates to the interplay between core
while lower energy states still remain confined to the core. This separation leads to electronic decoupling of higher-from lower energy holes states which is observed responsible for the slowed cooling.

#The Rise Of Open source Hardware So in the summer of 2012 Petrone (then an engineer at a Portland startup) launched a site where flexible matrix boards
Almost immediately Tindie began attracting favorable attention from the indie hardware community #and then expanded from there.
Today around 600 inventors sell more than 3000 different hardware products which have shipped out to more than 80 countries around the world.
Just as Etsy became the go-to marketplace for craft creators Tindie has become the primary hub for hardware aficionados.
We fill the hardware side.##While Petrone achieved his goal of creating a marketplace for hardware projects Tindie also inadvertently made a second contribution to the hardware world:
it now stands as the largest collection of open-source hardware on the planet. Nothing on the site is patented
and the vast majority of sellers have their source code and documentation links available right there on the page Petrone says.
Open source has become very much a part of the brand and what people within the hardware world associate with us.#
#Historically big companies have dominated hardware production for two simple reasons: manufacturing is both expensive and difficult.
Hardware requires physical objects which entail manufacturing costs and usually shipping. But a precipitous drop in prices#which some attribute to the rise of cell phones
which made components cheap#is helping to lower the barrier to open source entry for hardware as are crowdsourcing platforms such as Kickstarter.#
#For companies and makers the revenue model for open source hardware is still being worked out since a person could potentially exploit an open source platform and sell it for profit.
But as Arduino#a microcontroller for DIYERS and the most successful open source hardware project to date#shows people tend to buy the $30 original version rather than the $10 copycats.
#I think open hardware will start coming into its own in the next ten years Petrone says.
