Scientists makes first paper based transistor
Elvira Fortunato and colleagues from the Centro de Investigação de Materiais (Cenimat/I3N), at Faculdade de Ciências e Tecnologia, Universidade Nova de Lisboa, made the first Field Effect Transistor (FET) with a paper «interstrate» layer. A new device which rivals in electrical performance with the actual state of the art of oxide based thin film transistors (TFTs) produced on glass or crystalline silicon substrates. These results will be published next September in IEEE Electron Device Letters.
Nowadays, there is an increased interest in the use of biopolymers for low-cost electronic applications. Since cellulose is the Earth’s major biopolymer, some international teams have reported using paper as the physical support (substrate) of electronic devices. But, until now, no one had ever used paper as an interstrate component of a FET.
In a new approach, scientists from Cenimat/I3N – a research group coordinated by Elvira Fortunato and Rodrigo Martins – used a common sheet of paper as the dielectric layer on oxide FETs.
The research team fabricated the devices on both sides of the paper sheet. This way, the paper acts simultaneously as the electric insulator and as the substrate. «Is a two in one», says Elvira Fortunato.
Furthermore, electric characterization of devices showed that the hybrid FETs’ performance outpace those of amorphous silicon TFTs, and rival with the actual state of the art of oxide thin film transistors.
These results suggest promising new disposable electronics devices, like paper displays, smart labels, smart packaging, bio-applications, RFID tags, among others.

DiCaprio criticised over global warming crusade
Green campaigner Leonardo DiCaprio has come under fire for his attempts to raise funds to save polar bears - because he's using reams of paper to highlight the cause.
The actor, who wrote and narrated 2007 documentary 'The 11th Hour' to draw attention to global warming, recently sent out packages to members of the public in an effort to garner support for the Natural Resources Defense Council (NRDC)'s Polar Bear S.O.S. campaign.
The package contains a one-page letter from DiCaprio; two pages from Frances Beinecke, president of the NRDC; a flyer for a free Save the Polar Bear! bag; a donation form and petition to have the animals listed as an endangered species; and a return envelope.
The star has been criticised for the waste of paper and the hypocrisy of the situation - because he helped to spearhead the national Do Not Mail Registry campaign to ban junk mail earlier this year.
According to his representative Ken Sunshine, who also works for the NRDC, DiCaprio has no regrets about the way he has gone about publicising the plight of the polar bears.
When queried about the NRDC campaign, Sunshine tells the New York Post's gossip column PageSix: "Guilty as charged!", adding that DiCaprio's "environmental commitment is unending".

From CCTV to MTV: Paper on the Cheap
If bands could reach No. 1 on the music charts on the basis of ingenuity rather than sales, the amusingly irreverent, but unsigned The Get Out Clause easily would win.
Desperate to make a music video for their new single Paper, but with absolutely no money, the English band used footage of them playing in front of CCTV surveillance cameras that are deployed in and around their home city of Manchester to make the video.
Photographs, the music video of Paper and a video of the BBC interviewing the band are included. Just have a look at what they've done for yourself!! If bands could reach No. 1 on the music charts on the basis of ingenuity rather than sales, the amusingly irreverent, but unsigned The... more -
Cut and paste for paper heads
A Dutch artist has come up with a new, and exceptionally cool technique for making realistic life-size replicas of people's heads - out of paper!
Forty-two year old Rotterdam based artist, Bert Simons uses CAD coupled with various illustration programs to design his 3D paper portraits and sculptures.
To start with he first creates a computer model of a subject and then separates the model into its component parts. Once the template is created he prints it onto a bit of paper, gives it a bit of cut and paste, and voila! A life sized, realistic paper head.

Hemp: The New Billion-Dollar Crop
Popular Mechanics
February, 1938
Note: There was so little public attention and notice to the need for a ban on marijuana, or the resulting legislation (Marihuana Tax Act of 1937), that the editors apparently did not realize that it had already been outlawed when they published this article.
AMERICAN farmers are promised a new cash crop with an annual value of several hundred million dollars, all because a machine has been invented which solves a problem more than 6,000 years old. It is hemp, a crop that will not compete with other American products.

Hemp for Victory
US government propaganda film made during WWII touting the virtues of hemp. The film was aimed at farmers at a time when the military was facing a shortage of hemp, it shows how hemp is grown and processed into rope and other products.
Hemp can do so many things, but we need to immediately stop cutting trees for paper and switch to hemp and other annually renewable crops.
Hemp can help on a planetary scale.

Paper AK
For a new art project, the designer Martin Postler has investigated the history, the aesthetics and the lethal seductiveness of the Kalashnikov. He has freed the AK-47 from its terrible capacity to injure and kill by deconstructing it into a paper model construction set. At the end of the construction process each person can decide if they would like to hang their own AK-47 on the wall, paint it, customize it with stickers or simply burn it. Then ultimately this AK-47 thankfully remains a piece of paper.
