    Nano-Tech Thread!!!
    Hey guys I am into Nano-Tech and if no one cares too much I am going to dump any new Nano-Tech based technology in this thread...



    Breakthrough Could Mean 40-Hour Laptop Batteries (NewsFactor)
    Imagine running your laptop nonstop from New York to Tokyo -- crunch some numbers, work on a memo pop in a few DVDs -- and then do a full day of meetings, using your machine throughout the day and into the night. Imagine doing all this without ever plugging in your computer to recharge its battery.

    This scenario may become reality in the near future, if Stanford University scientists succeed in commercializing a breakthrough in the laboratory. Assistant Professor Yi Cui and associates at Stanford's Department of Materials Science and Engineering said they have developed a method to increase the life of rechargeable lithium ion batteries to a whopping 40 hours.

    Publishing in the journal Nature Nanotechnology, the Stanford researchers have shown that by using silicon nanowires as the battery anode instead of today's graphite, the amount of lithium the anode can hold is extended tenfold.

    Revolution in Battery Design

    "It's not a small improvement," Cui said. "It's a revolutionary development." And Cui means to move the development out of the lab as soon as possible. "We are working on scaling up and evaluating the cost of our technology," Cui said. "There are no roadblocks for either of these."

    Cui has filed a patent on the technology and is evaluating the formation of a company or licensing the technology to a battery manufacturer. Potentially two-day batteries could be on the market within "several years," he said.

    Silicon anodes are not a new idea. Researchers have known for some 30 years that they have the "highest theoretical charge capacity," but, until now, they haven't been practical because they change volume by 400 percent as lithium is inserted and extracted, the journal said. Cui's solution: a sponge-like network of tiny silicon nanowires, each of which expands but doesn't fracture.

    "Nanowires grown directly on the current collector do not pulverize or break into smaller particles after cycling," the journal reports. "Rather, facile strain relaxation in the nanowires allows them to increase in diameter and length without breaking."

    The Many Advantages of Nanowires

    Not only can the nanowires handle the extreme volume changes, they also "provide good electronic contact and conduction, and display short lithium insertion distances," Cui wrote. "We achieved the theoretical charge capacity for silicon anodes and maintained a discharge capacity close to 75 percent of this maximum, with little fading during cycling."

    The nanowires are grown directly on the metallic substrate that collects current, a process that has several advantages, Cui explained. First, the nanowires' small diameter can better accommodate the four-fold expansion in volume without fracturing. In addition, each nanowire is electrically connected to the metallic current collector, so all the nanowires contribute to battery capacity.

    The nanowires also offer efficient "charge transport" and eliminate the need for additives to conduct electricity, which add weight, the journal stated. In addition to Cui, the researchers were Candace K. Chan, Hailin Peng, Gao Liu, Kevin McIlwrath, Xiao Feng Zhang and Robert A. Huggins.

        "Nano-Tubes"..? Really..?? Now that's cool sh*t!

        I have read about these "Nano-Tubes" used in differant applications... What do you do specifically Pico.?

          not much, we just test its conductivity using different solutions. only played with it for a week. it is poisionous though, and it looks like bunch of black gunk on piece of glass.

          i htink poeple are trying to make transistors using nano tubes. but they're pretty hard to control when you "grow" them.

            i've been told AIDS is developed by the white men to kill the blacks and the gays

            i have no clue...i'll leave the science stuff to the experts. all i have to be concerned about is not to do what BAUS did...going barebacking in vegas with some random girl

              What is a Nano-Tube exactly..? I have read some about them but that was more about their applications... I understand they do grow and I think they are Nano-Fibers aren't they..?

              The one that stands out in my mind is that Discovery 2057 sh*t... They mentioned using Nano-Tubes for the space elevator being built...

              Interesting stuff Pico...

                I've had some computer problems this week and had to rebuild my computer but I'll be back soon to handle "that other thread"...

                I just saw this and I thought it was pretty interesting...




                Shape-shifting robot forms from magnetic swarm
                12:41 29 January 2008
                NewScientist.com news service
                Tom Simonite


                Swarms of robots that use electromagnetic forces to cling together and assume different shapes are being developed by US researchers. The grand goal is to create swarms of microscopic robots capable of morphing into virtually any form by clinging together. Seth Goldstein, who leads the research project at Carnegie Mellon University, Pittsburgh, in the US, admits this is still a distant prospect. However, his team is using simulations to develop control strategies for futuristic shape-shifting, or "claytronic", robots, which they are testing on small groups of more primitive, pocket-sized machines.
                These prototype robots use electromagnetic forces to manoeuvre themselves, communicate, and even share power.
                No moving partsOne set of claytronic prototypes were cylindrical, wheeled robots with a ring of electromagnets around their edge, which they used to grab hold of one another. By switching these electromagnets on and off, the so-called "claytronic atoms" or "catoms" could securely attach and roll around each other (see video, top right).

                The robot's wheels were not powered, so they had to rely entirely on their magnets to manoeuvre themselves around. "These were the first mobile robots without any moving parts," says Goldstein. They also used their electromagnets to share power, to communicate, and for simple sensing. Since using magnetic forces are less efficient at smaller scales, the team has now begun experimenting with electric forces instead. The latest prototypes are box-shaped robots dubbed "cubes" that have six plastic arms with star-shaped appendages at the end of each.

                These stars have several flat aluminium electrodes and dock together, face on, using static electricity. Electrodes on different stars are given opposing charges, which causes the stars to attract each other. Once connected, no power is needed to hold the stars together.
                Micro-scale robotsTests have shown that it is possible to send messages and power to other cubes over the same links. "Our hope is to assemble around 100 cubes to experiment with ideas," Goldstein says.
                Rob Reid at the US Air Force Research Lab is collaborating with the Carnegie Mellon team to develop even smaller prototype robots. Reid and colleagues can fold flat silicon shapes into 3D forms as little as a few hundred microns diameter.

                "We will drive those using electric forces too, by patterning circuits and devices into the silicon design," Goldstein says. He predicts that by the summer of 2008 they will have prototypes capable of rolling themselves around this way.
                Modularity is a popular theme with robotics researchers around the world. Other designs include Swarm-bots, Superbot, and M-TRAN. Complex connections"The physical mechanism for docking different pieces is really tough to do," says Alan Winfield, who works on artificially intelligent swarms at the Bristol Robotics Laboratory in the UK. "Most use mechanical latches with hooks." Although these physical connections are complex, they do not need power, Winfield points out, unlike magnetic connections.

                Using electromagnetic forces may make more sense at smaller sizes, he adds. "My guess is that electrostatic connectors will come into their own on the micro scale where less power is needed to have a large effect," he says.
                But software, not hardware, may be the biggest challenge facing researchers working on swarms of robots, he says: "Right now we just don't know how to design a system that produces complex overall behaviours from a group of simple agents."

                Ultimately, Goldstein believes his claytronic robots may one day achieve this, and much more: "I'll be done when we produce something that can pass a Turing test for appearance," he says. "You won't know if you're shaking hands with me or a claytronics copy of me."

                  I've been saying this since the debate for "stem cell" research began... You don't need a babies stem cells you can use your own...

                  Spare parts for humans..?

                  Finnish patient gets new jaw from own stem cells

                  By Sami Torma
                  Fri Feb 1, 1:47 PM ET

                  HELSINKI (Reuters) - Scientists in Finland said they had replaced a 65-year-old patient's upper jaw with a bone transplant cultivated from stem cells isolated from his own fatty tissue and grown inside his abdomen.

                  Researchers said on Friday the breakthrough opened up new ways to treat severe tissue damage and made the prospect of custom-made living spare parts for humans a step closer to reality.

                  "There have been a couple of similar-sounding procedures before, but these didn't use the patient's own stem cells that were first cultured and expanded in laboratory and differentiated into bone tissue," said Riitta Suuronen of the Regea Institute of Regenerative Medicine, part of the University of Tampere.

                  She told a news conference the patient was recovering more quickly than he would have if he had received a bone graft from his leg.

                  "From the outside nobody would be able to tell he has been through such a procedure," she said.

                  She added, the team used no materials from animals -- preventing the risk of transmitting viruses than can be hidden in an animal's DNA, and followed European Union guidelines.

                  Stem cells are the body's master cells and they can be found throughout the blood and tissues. Researchers have recently found that fat contains stem cells which can be directed to form a variety of different tissues.

                  Using a patient's own stem cells provides a tailor-made transplant that the body should not reject.

                  Suuronen and her colleagues -- the project was run jointly with the Helsinki University Central Hospital -- isolated stem cells from the patient's fat and grew them for two weeks in a specially formulated nutritious soup that included the patient's own blood serum.

                  In this case they identified and pulled out cells called mesenchymal stem cells -- immature cells than can give rise to bone, muscle or blood vessels.

                  When they had enough cells to work with, they attached them to a scaffold made out of a calcium phosphate biomaterial and then put it inside the patient's abdomen to grow for nine months. The cells turned into a variety of tissues and even produced blood vessels, the researchers said.

                  The block was later transplanted into the patient's head and connected to the skull bone using screws and microsurgery to connect arteries and veins to the vessels of the neck.

                  The patient's upper jaw had previously been removed due to a benign tumor and he was unable to eat or speak without the use of a removable prosthesis.

                  Suuronen said her team had submitted a report on the procedure to a medical journal to be reviewed.

                      i guess that means fat people can produce more stem cells? this will certainly balance out the US trade deficit.

                        Great news from Finland.

                        Could have been the US, but any type of progress here is blocked these days.

                          The Skinny On 'Miracle' Wrinkle Cream

                          A new wrinkle cream that promises fabulous results. But the question everyone's asking is "what's in that cream?"

                          Barbara Blair says this new gel she's been using makes her face look a lot younger than the Retin-A and vitamin C creams she's been using.

                          "It's really tightened my skin. Firmed it. The little lines are much better. The texture is very appreciably different."

                          What Blair probably doesn't know is that a key ingredient in the cream is the foreskin of a circumcised baby.

                          The skin that would otherwise be tossed away. It was first made into a product that helped burn victims heal. Now it's in this antiwrinkle gel, called TNS Recovery Complex.

                          Betsy Rubenstone is the aesthetician in the plastic surgery department at the University of Pennsylvania and she swears by this stuff.

                          She knows why the foreskin is used.

                          "It's filled with everything we begin to lose as we age," Rubenstone says. "And that includes growth factors, amino acids, proteins, collage, elastin and holyuronic acid."

                          Thomas Jefferson University Hospital dermatologist Paul Bujanauskas says while TNS might have merit, he would not prescribe it for his patients because no scientific research proving its value has been published in medical journals.

                          The cost of one bottle of TNS is about $130. And that will last you about a month and a half. How does it smell? Well that's another downside. Just ask anybody who uses it.

                          "It's disgusting. It's got a sour smell to it that makes you want to gag," says Blair. "But you get used to it."
