A nanotech solution to wrinkled skin
2008-04-05 06:59:00 A nanotech solution to wrinkled skinhttp://www.rsc.org/chemistr-yworld/News/2007/January/090106-02.asp Those of us unhappy with our ageing skin may find solace in nanotechnology. Researchers who have discovered that nanoparticles prevent thin polymer films from buckling say their concept could be applied to stop human skin wrinkling too. Nanoparticles are already marketed in cosmetic skin products; usually because they can penetrate much deeper into skin than conventional creams, delivering vitamins that are supposed to plump and soften the skin, reducing wrinkling. The approach of Ilsoon Lee, of Michigan State University, US, is somewhat different: nanoparticles in sufficient concentration, he suggests, may stop the skin ever wrinkling in the first place.That's because the same underlying principles of wrinkling lie behind human skin and the polymer film systems which Lee has been investigating. Human skin, Lee says, consists of a thinner outer layer (the epidermis, around 50-100 ?m...
Promising New Nanotechnology for Spinal Cord Injury
2008-04-02 22:13:00 A spinal cord injury often leads to permanent paralysis and loss of sensation below the site of the injury because the damaged nerve fibers can't regenerate. The nerve fibers or axons have the capacity to grow again, but don?t because they're blocked by scar tissue that develops around the injury. Northwestern University researchers have shown that a nano-engineered gel inhibits the formation of scar tissue at the injury site and enables the severed spinal cord fibers to regenerate and grow. The gel is injected as a liquid into the spinal cord and self -assembles into a scaffold that supports the new nerve fibers as they grow up and down the spinal cord, penetrating the site of the injury.When the gel was injected into mice with a spinal cord injury, after six weeks the animals had a greatly enhanced ability to use their hind legs and walk.The research is published today in the April 2 issue of the Journal of Neuroscience."We are very excited about this," said lead author John Kes...

Strength Is But Skin Deep at the Nanoscale
2008-03-13 21:01:00 For centuries, engineers have bent and torn metals to test their strength and ductility. Now, materials scientists at the University of Pennsylvania School of Engineering and Applied Science are studying the same metals but at nanoscale sizes in the form of wires a thousand times thinner than a human hair. This work has enable Penn engineers to construct a theoretical model to predict the strength of metals at the nanoscale. Using this model, they have found that, while metals tend to be stronger at nanoscale volumes, their strengths saturate at around 10-50 nanometers diameter, at which point they also become more sensitive to temperature and strain rate. Such prediction of different strength regimes of nano-solids is important for future application and engineering design of nanotechnology.Such small-volume materials with relatively large surface areas are now routinely employed in microchips and nanoscience and technology, and their mechanical properties can differ vastly from th...

Nanotech applications in Cancer treatment - Today!
2008-03-03 21:06:00 Once again the modern technology available to us today that just simply wasn't 20 years ago...or 10...or heck 18 months ago is remarkable. Cancer researchers believe that further engineering the shape or surface properties of nanoparticles can enable the particles to actively target tumors, and thereby maximize their diagnostic or therapeutic function at the cancer site, while minimizing collateral damage to healthy tissue This is merely the beginning, for this early nanotech being tested is for better, more targeted deployment of current medicines. "We're not trying to re-invent every aspect of the science," said Seth Feuerstein, president of Carigent Therapeutics in New Haven, Conn. "We focus on delivering current drugs better, and we're also working with companies whose drugs haven't yet been approved, to help make them more effective." It may remain primarily a deployment mechanism, but even so this could be a harbinger of the end of chemotherapy. I kno...

Nokia’s nanotech Morph goes on display, signals melting devices in our fu
2008-02-26 08:22:00 Why is Nokia always trying to outdo everyone with its fancy-schmancy concepts and designs? Why can’t they just get in line and keep it simple? We may never know the answer to those questions, but what we do know is that the company is presenting a new concept device called the Morph that would be right at home… in the year 3000. The unit is included in the MoMA’s “Design and the Elastic Mind” exhibition catalog, and boasts the ability to stretch and flex to almost any shape a user could think of. The nanotechnology-based device would deliver transparent electronics, self-cleaning surfaces, and the malleability to transform into any number of configurations. Of course, the actual technology required to put this together is years or even decades away, though Nokia expects to see some of these innovations making their way into high-end products within seven years. See the device doing its thing in some photos after the break.

Windshield Without Wiper Powered By Nanotech
2008-02-25 03:03:00 New idea of Fioravanti for its twentieth year of operation, the company founded by the famous designer who for years has made the history of Pininfarina (almost all his most beautiful Ferrari) has just proposed the first car without wipers. A prototype baptized Hidra that thanks to the use of nanotechnology in a special aerodynamic study can keep clean the windscreen, while not having any brush.Everything stems from a special glass that thanks to four sophisticated surface treatments change the characteristics of glass at the molecular level. The first (in contact with the outdoor air) is based on titanium dioxide: filters the sun but, above all, gives the windscreen a strong hydrophobic effect. The second layer of glass is actually made up of microscopic dust pushing dirt on the sides of the glass, in turn activated by sensors placed in the third layer forming clean the windshield as needed (quantity of water or dirt for disposal). And 'Unbelievable as it is a conductor of electri...

2007-11-18 15:20:00 PC Mag has reviewed the Dell XPS One, the machine which we originally revealed on these here pages. The unit they got their hands on was the top-end $2,399 model -- what, you think Dell would risk lumping 'em with the budget range? -- and the overall impression was very good if you limit yourself to the praise of the PC's numerous features. A built-in HDTV tuner with remote, Blu-ray, and 802.11n round out the 2.33GHz Core 2 Duo, 2GB of RAM, and 500GB HDD. The reviewer also thought that the design was a strong aspect of the XPS One, matching the iMac for aesthetics and minimalism. From there it's downhill: the Radeon 2400 HD graphics card is crap for gaming, and the unit as a whole isn't price competitive thanks to the 20-inch 1680x1050 screen. Will you wait for the 24-inch model?

Terabyte nanotech thumb drives around the corner?
2007-10-29 01:55:00 Wired has a write-up of a new storage technology developed at Arizona State University that could produce flash thumb drives capable of storing terabytes of data in the near future, that also happens to be cheaper and more energy efficient than flash memory. The new technology has been branded programmable metallization cell, and differs from present storage technologies in that it "creates nanowires from copper atoms the size of a virus to record binary ones and zeros. " It all sounds very interesting -- if slightly too optimistic -- to us, and we'll get to find out relatively soon just how effective the new chips are: Arizona State's business arm has licensed the technology to three companies, which may be ready to sell a product containing the chips within 18 months.

Mazda announces new nanotech catalyst material
2007-10-02 02:07:00 Mazda has just announced that they've developed a new base material structure for catalytic converters. The key to the new material is a structure that allows catalyst particles of less than 5 nm to be embedded into the material. That should help keep the particles from clumping together in the heat of the exhaust stream. When the catalyst material clumps, the effective surface area is cut and more platinum and palladium need to be used to achieve the desired effect. Mazda's development should help cut the cost and increase the effectiveness and durability of the catalytic converter.
