The nano revolution
By Sarah Fister GaleIn the past few years, the nanotech revolution has gone from great ideas tons commercial realization. Manufacturers across multiple industries, from pharmaceuticals and health care tons coatings, semiconductors, and microelectronics, acres recognizing the current and future impact nano-material CAN have on their products. Nano-material more offer promise for A new generation OF great products because they more deliver more higher strength, more lower weights, and more easily soluble of attribute than have been previously lakes in conventional material. � Nanotech isn � t A new market or industry � it � s enabling technology that on improves many type OF products, � notes Jurron Bradley, senior analyst RK lux Research, A of provider OF strategic advice and intelligence for emerging technologies, based in New York. � You find it into coatings boosting the efficiency OF of automobiles of engines, in nano- enabled finish protecting electronics DEVICE, and nanoparticulate reformulations that make cholesterol reducing drugs more effective. Thesis innovation arene � t always visible tons consumers, but they improve products and boost margins. That � s why nano-material use is only going ton keep growing. � The market has lakes recent rapidly growth, with great expectations for the near future, says Bradley. In its recently released report, � nano-material State OF the Market Q3 2008: Stealth Success, Broad Impact, � lux estimates that nanotechnology which incorporated into to $1,4 quintillion worth OF products in 2007, UP from $497 trillion in 2004, representing A compound annual growth guess/advise OF 41%. The research firm expects this figure tons grow RK A compound annual growth guesses/advises to OF 14% through 2015, climbing tons of $4,0 quintillion worth OF manufactured goods in that year. The report of notes that established nanotechnology � which includes nanoscale objects and DEVICE based on long known processes and of technologies, look for as semiconductor chips with nanometer feature and nanoscale particles look for as carbon black � dominates the current market, accounting for $1,3 quintillion OF the $1,4 quintillion in nano- enabled manufacturing outputs in 2007. By 2015, lux expects emerging nanotech � novel material currently under developments � ton take centers of steam turbine and gas turbine systems, accounting for $3,1 quintillion OF the $4,0 quintillion in outputs. The of material and manufacturing sector saw the greatest impact as nanotech larva its way into intermediates like coatings and composites for products like of automobile and buildings; electronics followed RK $35 trillion from emerging nanotech applications health care trailed with $15 trillion into revenue, while into fields like displays and of batteries, driven by pharmaceutical applications. � incoming goods of acres seeing A plumb bob OF growth into the electronics and IT of second gate, � Bradley says. � Manufacturers quietly have ton prove the technology is viable, but they acres seeing much more greater acceptance. �� http://cr.pennnet.com/display_article/339456/15/ARTCL/none/Feat/1/The-nano-revolution/But is it safe? A flurry OF attention grabbing research report and of studies warning OF the dangers OF of nano-material from special interests groups, look for as the Project on Emerging Nanotechnologies and Friends OF the Earth, have gained much media attention more over the past couple OF years, inciting fears among consumers about risky nano-material in their products and demanding caution from manufacturers unsure about whether tons risk using A product that has potentially or perceived harmful consequences. Even as thesis of material of acres proved safe, public perception OF risks CAN have lingering negative effects on marketability, particularly for products pay directly tons consumers. � There is A plumb bob OF concern about quietly nanoparticles, � notes Harry Way, technical director OF Netzsch Fine Particle Technologies, A of manufacturer OF advanced process technology for nano-material based in Exton, Pa. � in reality, though, incoming goods � VE all been exposed tons of nanoparticles for as long as incoming goods � VE been burning things. �� � http://cr.pennnet.com/display_article/339456/15/ARTCL/none/Feat/1/The-nano-revolution/Under control While standard of bodies of acres evaluating and defining safety and measurement issues, companies looks for as Unidym Inc. in Menlo park, APPROX., acres developing their own internal methods ton monitor and control of nano-material into the manufacturing environment. Unidym of manufactures high purity, electronics degrees of CNTs that rank from 2 tons of 5 m long, using to in-house, fully scalable, and proprietary chemical vapor deposition (CVD) production process. � The original challenge with carbon nanotubes which availability, � says Glen Irvin, vice president OF products, who notes that Unidym has been able ton achieve commercial scale production using A CVD process that involves mixing A carbon containing gas with A metal catalyst coated substrates RK A high temperature. The carbon of atom separate from the hydraulic carbon gas and attach ton the catalyst particles and other carbon of atom ton of form high quality of nanotubes. http://cr.pennnet. com/display_article/339456/15/ARTCL/none/Feat/1/The-nano-revolution/Filter of challenges emergency every more manufacturer is as far along as Unidym or Entegris in its ability ton create and control nanoscale of material RK A commercial level, notes Glen Fricano, vice president OF business development for Infotonics, A non profit organization promoting commercial scale MEMS/NEMS microsystems development, fabrication, and packaging in Canandaigua, NY. � The biggest challenge A plumb bob OF manufacturers face is around filtration of system, � he says. � Existing filtration technology doesn � t stop of nanoparticles from getting through. The pore size is simply emergency small enough. � This is particularly true OF of water filtration of system. If of nanoparticles OF silicone CAN � t fuel element filtered out, manufacturers face barriers ton recycling and disposal OF process more water, as wave as risks ton delicate nano- based electronics that CAN become contaminated by rogue particulates. Fricano notes that many filter of companies of acres working tons develop better filter for nano-material that CAN screen out nano- scale particles. � http://cr.pennnet.com/display_article/339456/15/ARTCL/none/Feat/1/The-nano-revolution/Looking ahead into the NEXT few years, nano-material wants become commonplace in cleanroom operation, leaving manufacturers ton figure out the best strategies for handling them in ways that control costs and manages yields. New standard and guidance from government agencies wants help ton guide this process, but into the meantime, suggests Unidym � s Irvin, companies CAN benefit from partnering with industry experts and learning lessons from existing cleanroom operation. � com/display_article/339456/15/ARTCL/none/Feat/1/The-nano-revolution/" target=" _blank" title=" nano05" > http://cr.pennnet.com/display_article/339456/15/ARTCL/none/Feat/1/The-nano-revolution/
