May 30, 2003 – The co-founder of a nanotechnology startup that prides itself on its modeling capabilities predicts the industry will have commercialized design software tools like those used for microsystems, but not anytime soon.

He and other nanotech experts said the growth of nanoscale design tools will require a critical mass of people working on common products and acceptance by the field’s do-it-yourself software developers.

“Up to now, there’s been no real demand for it,” said Marvin Cohen, a physicist at University of California, Berkeley, and co-founder of California-based Nanomix Inc. “Right now, everyone develops their own.”

Cohen has been doing that for four decades at Berkeley.

Along with colleague and Nanomix co-founder Alex Zettl, Cohen developed a way to build carbon nanotube structures that act as chemical sensors. They also work on hydrogen storage systems for fuel cells. Their primary strength has been using theoretical modeling to predict the behavior of nanostructures.

Cohen devised a model that describes how materials are put together on the atomic level. The model, based on theories he has been developing since the 1960s, is used worldwide to calculate the properties of metals, superconductors and semiconductors.

He said the benefit is someone can theoretically figure out how things work at the nanoscale, saving time and money over trial-and-error approaches before taking a nanodevice into the laboratory. Nanomix is using Cohen’s proprietary techniques to virtually synthesize materials and predict electronic, physical and chemical properties of carbon nanotubes with a high degree of accuracy.

“To model how a nanotube will react to a given atom, whether it’s anthrax or carbon dioxide or hydrogen, you can use these techniques,” he said. There’s no reason to believe there won’t be as many applications of these approaches … as there are in the MEMS area.”

The field is broad, but Cohen can see ultimate demand for standard tools that all nano companies will face, such as a commercial software platform for testing and explaining properties of materials or particles.

Tim Harper, chief executive of nanotech business research firm Madrid-based CMP Cientifica,  said there will be great software opportunities for nano, but it will require a critical mass of people focusing on one particular area — and that type of standardization doesn’t exist. For now, he said, many researchers take a cobbled approach: using general computer modeling and simulation suites and writing programs for their specific needs. “It ain’t pretty,” Harper said.

“We come across a lot of companies that say, ‘We’re in the Valley and in the software business. We’re going to develop software for nanotech.’ We say, ‘What particular flavor of nano?'” he said. “It’s like writing software applications for electricity. First you have to figure out if you’re writing software for a microprocessor or a toaster.”

One startup hoping to break into the space is California-based Junius Tech Inc., a nanoscale design and consulting services firm with technology and expertise from Stanford University and NASA. Today, the privately funded firm leans more toward providing services to outside firms, but co-founder Jonathan Woo said it is developing simulation software products.

The broadness of the technology is a risk to early players, Woo said, but Junius hedges its bets by offering customized consulting while it makes standardized tools for modeling and simulating nanomaterials for several applications, including electronic, optical, energy and biotech.

“It’s an evolution,” he said. “Think about any new technology that comes in — you have to grow with the industry.”

For now, however, most of the work is centered on research labs. The National Science Foundation-funded Network for Computational Nanotechnology at Purdue University provides access to simulation tools and services, develops new theories and approaches for simulation and links computational and experimental scientists to solve problems.

Rice University received a supercomputer from IBM to calculate interactions of subatomic particles in carbon nanotubes. IBM provided the $1 million system under a Shared University Research Award, which it gives to universities in fields of mutual interest. The partnership will allow IBM to develop more sophisticated software and systems applicable for nanoscale science and technology.

Cohen said most research funding is funneled into government and academic labs, and much of the work coming out is promising. Still, he cautioned against getting too excited about a rapidly rising market for software tools.

“I think it’s generally agreed that nanoscience is very healthy … (but) the commercial aspects of the field are not developed at this point,” he said. “The small companies, you hear a lot about them, but often the main product is hype. It’s just going to take a while.”

NEW YORK — Some threw strikes. Some were low and outside. But nine startups with major league dreams each got a shot at winning investor interest as part of NanoBusiness Spring’s Bootcamp for Entrepreneurs.

Moderated by Ben Savage, an associate with private equity firm Wasserstein & Co. and Ari Ginsberg, director of the center for entrepreneurship at NYU’s Stern School of Business, “The Pitch” gave a lineup of young companies the chance to polish the 15 minute version of their business plan in front of an audience of potential investors.

The pitches were as varied as the pitchers. Some were polished, professional and persuasive. Some were of the Ph.D.-with-a-dream-and-a-patent variety. But all were innovative.

Screwball: Chiral Technologies hopes to produce filters or modulators for optical networks from a patent on making optical fiber with a special nano-spiral twist in its core. CEO Dan Neugroschl also believes the company’s candy-striped fiber can be integrated with less expensive lasers to provide “twice the power at half the price.”

Spitball In the morning session, Emanuel Barros, chief technology officer for two-month-old NanoMatrix, presented a cost-effective system that can cut or etch submicron structures using tiny jets of water. Barros, who left NASA’s Ames Research Center to start NanoMatrix, said the process was inspired by a kind of shrimp that stuns prey with powerful water jets.

Whiskeyball: Yuval Avniel of MicroPowder Solutions described his company’s simple, intriguing method for creating thin films from two or more materials. By carefully alternating how different atoms are deposited on a surface, Avniel said, the process could allow scientists to “put atoms together like Lego blocks.” It could, he said, be applied to create multifunctional coatings that might be both wear-resistant and electrically conducting. He also envisioned the process being used to create nanoscale fuel cells, filters or wires.

Avniel said the technology has been developed on something less than a shoestring. “My colleague in Belarus agreed to make our samples in exchange for a case of Johnny Walker,” he said. He’s now looking for strategic partners and seed capital.

Curveball: Jayesh Doshi, chief executive and founder of eSpin Technologies in Chattanooga, Tenn., is looking for $3 million in funding to enable his company to rapidly and dramatically increase its production of nanofibers. Doshi said eSpin, founded in 1999, already has more than 30 customers, including the U.S. Departments of Energy and Defense, NASA and TRW.

The company’s nanofibers, which can be “electrospun” from a variety of materials, including carbon and nylon, could provide superior performance in automotive air, oil and gas filters. For commercial production of nanofiber air filters, Doshi said, eSpin has to ramp up to produce eight million yards of material.

Other nanofiber applications in eSpin’s arsenal: use in ultracapacitors for energy storage, filtering blood, viruses and biomolecules, creating strong, lightweight materials.

Buckyball: Like many scientific discoveries, Luna nanoMaterials’ metal-filled buckyballs, soccer-ball shaped carbon molecules filled with three metallic ions and a nitrogen atom, were a happy accident.

As CEO Kent Murphy explains, Harry Dorn’s team at Virginia Tech were trying to make “regular” buckyballs when a bit of air leaked into the reactor. The error lead to a whole new class of materials that the company calls Trimetaspheres. The buckyballs don’t break down in the presence of oxygen and can withstand heat up to 300 degrees Celsius, he said.

Now it is looking to produce them commercially as a highly effective contrast agent that could make MRI images and the diagnoses derived from them significantly better.

Murphy said that the buckyballs are 50 times better than the current best-selling contrast agent, called Magnevist, which controls more than 60 percent of the billion-dollar market for MRI contrast agents. What’s more, Magnevist’s patent is about to expire. Murphy also contends that Luna’s agent could make MRIs more useful and less expensive by requiring patients to ingest less of a contrast agents and allowing smaller magnets to be used in MRI machines.

The company has done tests in small animals and is looking to raise $7 million the get started on toxicity studies before moving to phase 1 clinical trials in humans. Ultimately, Murphy said, the company’s exit strategy is to be acquired.

So how did umpire/moderator Ben Savage see the game. “It’s well known that venture capitalists don’t like to fund science projects,” he observed. Savage thought that one pitcher, BigBangwidth, a company based in Edmonton, Alberta, which aims to produce local network devices that offer “ethernet on steroids” via nanoelectronics, had commercial promise.

But overall, he has an investor’s cautious, risk/reward driven perspective on small tech. “Many of these markets and almost all of these technologies are uncertain,” he said.

He also noticed that while all nine companies that participated in The Pitch had some degree of “smallness” about their technologies, they were in a wider range of business sectors.

Echoing a theme heard throughout the conference, Savage noted that “nanotechnology is not an industry, but a set of technologies spanning a wide range of businesses.” To assess small tech-powered startups, investors have to look at them not through nano-tinted glasses, but with expertise in whatever sector a new company may be looking to enter.

May 21, 2003 — Feature-rich portable devices are getting hungry for more and more power. So, the race is on to meet the demands of energy-sapping digital multimedia through portable, powerful micro fuel cells (MFCs) that outlast rechargeable batteries. The companies that succeed have a billion-dollar market waiting for them.

The problem is, there are so many business and technology barriers in their way, MFCs will probably remain niche products for the next several years.

According to David Redstone, editor of Hydrogen and Fuel Cell Investor, no firm has demonstrated a commercial prototype with sufficient power in a small enough package that can fit inside a notebook computer, much less a mobile phone. Redstone said only one MFC maker, Medis Technologies Ltd., has reported achieving a “volumetric energy density” — or the ratio of energy output to its volume — that surpasses lithium ion batteries.

Nonetheless, MFC companies are attracting attention. In February, President Bush made a call on a mobile phone powered by a prototype from MTI MicroFuel Cells Inc. The president actually held the power pack in one hand, the phone in the other, with the two connected by a cable.

But early market entry won’t be found in the West Wing. It will happen first in more industrial settings, where it’s critical that wireless devices can be charged instantly and run longer. MTI Micro said it would integrate MFCs into one of Intermec Technologies Corp.’s industrial wireless hand-held devices sometime in 2004, but would not say what size the fuel cell would be.

Portable power generation in remote locations will likely be another early market. New York-based Medis Technologies is building a fuel cell auxiliary charger to power a military PDA being developed by General Dynamics. Medis is aiming for commercial production in 2004. Redstone projects that Medis’ technology will cost between $2.50 and $3.50 a watt, vs. $5 a watt for lithium ion rechargeable batteries.

Jim Balcom, president of PolyFuel Inc., an Intel-funded startup that makes the critical membrane component for micro fuel cells, said that a prototype debuted in a laptop at the Intel Developers Conference in February. Balcom said the improved performance of PolyFuel’s membrane over a rival made by DuPont should help MFC makers reduce the size of systems.

Atakan Ozbek, director of energy research with Allied Business Intelligence Inc. and author of a new report on micro fuel cells, said his firm is less bullish on the near-term future for MFCs than it was three years ago — in part because some companies have delayed their prototypes. Nevertheless, Ozbek’s report predicts that the market for micro fuel cells will grow from a few commercial products in 2004 to 50 million units in 2010.

In the next two years, Ozbek said, MFC makers will have to solve technical problems before they can integrate them with larger devices — challenges that larger companies are better equipped to solve. That’s why Toshiba, Samsung, Hitachi, Motorola and NEC may come to dominate the fuel cell market.

Most analysts believe MFCs and rechargeable batteries will end up operating together to meet the sudden spike in power demands. Future small tech innovations in materials and microsystems may help shrink micro fuel cells to the sizes and power densities they need to reach. NEC is developing fuel cell electrodes that employ “nanohorns,” a variant of carbon nanotubes, to improve performance, and reports it will begin shipping fuel cells for laptops in 2004.

Neah Power Systems Inc. has developed technology based on microscopic channels machined into a cube of silicon and lined with catalytic nanoparticles. Methanol fuel and hydrogen peroxide interact to produce electricity. “Just as Wi-Fi is cutting the cord to Ethernet connections, we’re aiming to help sever ties to the AC power outlet,” said Gregg Makuch, Neah’s marketing director.

The ultimate question for competitors in the MFC market is when. “Medis should be commercial in two years,” said Redstone. “Neah could easily be six years away.”

April 16, 2003 – GSI Creos Corp. of Japan has developed metal-supported catalysts using a carbon nanofiber that could be used in electrodes for fuel cells, according to the Jiji Press English News Service.

The new catalysts are cheaper to make because they require less platinum in their manufacturing process, the report said. GSI’s nanotech team developed the catalysts with Shinshu University Professor Morinobu Endo, according to the report.

ESpin Technologies Inc. wants to be a major producer of nanofibers for the filtration and other industries. It uses a process known as electrospinning, which combines electrostatics, polymer sciences, fluid mechanics and engineering. Electrospinning was first used in the textile industry during the mid-1930s, but its application in other industries has been limited.

But eSpin is not repeating what other companies have done. Armed with a $2 million federal grant from the Advanced Technology Program (ATP), it’s developing a special high-speed device to overcome two traditional barriers to electrospinning: high production costs and low output of material. “The real success will come when we can successfully commercialize technology to produce fiber economically,” said Jayesh Doshi, eSpin’s president and chief executive.

Nanofibers are up to 100 times smaller in diameter than conventional textile fabrics. Experts say that the smaller size translates into significant cost and performance improvements. Here’s how electrospinning works: A high voltage is applied to a thin tube that contains a polymer solution. The voltage ejects a continuous stream of liquid, which is then split into very fine jets of fluid. The evaporating solvent creates fibers that are collected and formed into layers, or nanofiber mats.

null

eSpin has successfully commercialized mats of electrospun fiber 50 to 100 nanometers in diameter. Its nanofibers are used to develop filters for fuel cells, heating and air conditioning systems, and for aerospace and automotive parts. Other possible uses include cosmetics, paint additives and medical devices.

null

Company sales approached $1 million in 2002, said Doshi. He declined to identify client companies, saying only that they include some of the “bigger players” in the filtration industry.

null

eSpin produces about 10,000 yards of nanofiber per day — far below the needs of major filtration companies. “We have one customer that would like to have 50 million square yards a year. That’s (only) one customer, and there are hundreds of filter companies,” Doshi said.

null

The fiber sales have helped eSpin invest money in its new machine, which could be ready for full-scale production as early as this year.

null

The payoff could be worth it. According to the McIlvaine Co., a Northfield, Ill., market research firm, the global market for filtration media could reach $75 billion by 2020.

null

The large surface area of nanofibers — about 100 times smaller in diameter than conventional textile fibers — offer significant performance advantages, experts say. However, no commercial processes exist for affordably making nanofibers in quantities sufficient for large-scale manufacturing.

null

“Nanofibers never really became fabrics,” said Darrell Reneker, a professor of polymer science at the University of Akron in Ohio. “It costs more to make them, so you really have to want surface area, which is what you buy when you make nanofibers: surface area per unit mass.”

null

Doshi said eSpin’s proprietary device could produce large volumes of nanofibers at lower cost than existing technologies allow. As the technology matures, eSpin expects sales to the filtration industry to account for about $20 million annually within five to seven years.

null

“We are hoping to have several (filtration) products developed, and also to perfect the art of making those products,” said Doshi. “Then it will be a matter of putting things together for manufacturing in large-scale quantities.”

null

Large filtration companies could emerge as competitors, though. Donaldson Co., a huge filtration system maker in Minneapolis, has patented nanofibers made using an electrospinning process.

null

eSpin, which is self-funded, has 11 full-time employees, and expects to move soon from the Chattanooga Area Chamber of Commerce’s Business Development Center. Doshi said the company will add additional staff once its new manufacturing device is ready for production.

    — Research by Gretchen McNeely

    March 28, 2003 — Pacific Fuel Cell Corp. (PFCE) has developed a process to grow carbon nanotubes on carbon cloth paper for micro fuel cells, according to a company news release.

    The Tustin, Calif.-based firm said researchers at University of California, Riverside, discovered the process, which uses chemical vapor deposition. PFCE signed a contract with the university to research and develop a fuel cell prototype based on the firm’s carbon nanotechnology.

    Low-cost nanotube production is a key part of PFCE’s plan to develop micro fuel cell technology to replace batteries in laptops, cell phones and other consumer electronics, the release said.

    TOKYO, March 25, 2003 — Twelve years after NEC Corp.’s Sumio Iijima discovered the carbon nanotube, the company’s fuel cells — powered by a variant called the carbon nanohorn — are getting ready to power portable devices.

    Click here to enlarge image

    Yoshimi Kubo, senior manager of NEC Fundamental Research Labs’ Nanotube Technology Center, said the fuel cells will start shipping for laptops in 2004 and cell phones in 2005.

    In a demonstration at a nanotech conference in Japan late last month, Kubo showed mockups of a fuel cell that ran an NEC laptop and a smaller fuel cell that operated an NEC mobile phone. The 400-gram, 12-volt notebook fuel cell was still about the size of the computer’s display, but had no problem providing the 18 watts necessary to boot the laptop. The mobile phone fuel cell can already provide the 3 watts needed for Japan’s 3G phones, he said.

    NEC’s methanol-fueled polymer electrolyte cells, using 100-nanometer nanohorn clumps dusted with platinum catalyst particles, can theoretically achieve up to 10 times the power density of lithium ion batteries. Next year, NEC will produce methanol-fueled power cells the same weight as lithium ion batteries that will run for about 16 hours, he said.

    “We have two choices: We can make them at the same weight as lithium batteries, but they’ll last three times longer, or we can make them a third smaller, so they’ll run about the same time [4-6 hours]. The probable route is the same size, but three times the running life,” he said.

    Kubo said NEC will initially supply fuel cells for its own laptops late next year, and cell phones in 2005 and will then probably seek to license the technology to other battery makers. NEC subsidiary Tokin Corp. could possibly produce the cells, but that hasn’t been decided yet.

    IDC Japan estimates that NEC sold 1.6 million laptops worldwide last year, coming in seventh with a 5.6 percent share. But 1.3 million of those were sold in Japan, where NEC claims number-one status with a 21.5 percent share where its customer base of first adopters lies. Similarly, NEC is nowhere on the international market with mobile phones, but in the domestic market the company claims a 32 percent share of mobile phones here, representing about 3 million units annually.

    Beyond that, Kubo believes fuel cells will capture half the global market for mobile devices in the second half of the decade and NEC will capture “20-30 percent” of that.

    These are big claims indeed, say analysts, who question assumptions that fuel cells will eat up huge market share. Up for grabs, says research firm Frost & Sullivan, is a world rechargeable-battery market that in 2001 was about $72.6 million for laptops, $5.4 million for PDAs and $396.2 million for mobile phones.

    Barry Huret, president of Huret Associates Inc., a battery consulting company, called the rechargeable battery market “flat” and is skeptical that fuel cells will eat up market share anytime soon. “While many companies are working on miniaturized fuel cells, none of them seem to be there yet. Fifty percent seems very high to me — unless it is limited to specific segments — and then it will become a cost and availability issue. I don’t see it happening near-term,” he said.

    NEC is in for some tough competition. Manhattan Scientifics Inc., MTI MicroFuel Cells Inc., Neah Power Systems Inc. and Toshiba Corp. are all touting commercialization of rival technologies in 2004.

    Hyunji Lee, public relations officer for Samsung Advanced Institute of Technology, said Samsung has developed a prototype for mobile phones, but won’t say when it will commercialize the product. Casio has a power pack prototype that the company says can drive a notebook for 20 hours and, according to spokesman Akira Watanabe, will hit the market in March 2005.

    Such competition means NEC will at best be just another player, said Shinji Thomas Aquinas Shibano, Japan Research Institute Co. Ltd.’s science division general manager. “Carbon nanohorns are a good material and I think NEC’s technology has strong potential for high-power fuel cell batteries instead of low-power ones such as PDAs, where competitors are already making liquid-based fuel cell batteries,” he said.

    Frost & Sullivan battery analyst Sara Bradford thinks NEC is “in line” with competitors, but capturing a third of the market is more doubtful. “At this point in the technology development and commercialization process, it is anyone’s guess at what type of design will ultimately succeed. As is, there are many barriers these designers will face once they finally commercialize the technology.”

    “First,” she said, “what distribution channels will be best suited to get the product to the consumer? Will the OEMs of the equipment work seamlessly with the fuel cell developer for an integrated energy source?”

    Kubo said decisions on these issues have yet to be made. And before any of this happens, NEC needs to reduce the cost of carbon nanohorns from today’s $500 a gram to just one dollar a gram.

    March 24, 2003 — Case Western Reserve University of Cleveland announced that Chung-Chiun Liu, a professor of sensor technology and control and director of the Electronics Design Center at the university’s engineering school, received the Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring.

    Liu was among 10 individuals and six organizations to receive the award. Liu has mentored high school students for 16 years. His proteges have achieved top honors at national-level science fairs. His students’ research has focused on fuel cells and microelectrochemical sensors.

    March 11, 2003 — MesoFuel Inc. of Albuquerque, N.M., and Jadoo Power Systems LLC of Folsom, Calif., announced a strategic partnership to jointly develop fuel cell products.

    Under the collaboration, the companies will combine MesoFuel’s microscale technology-enabled hydrogen generators with Jadoo’s fuel cells in order to create portable hydrogen power systems that run longer than present systems.

    Altair issued third patent


    February 3, 2003

    Feb. 3, 2003 — Altair Nanotechnologies Inc. received a patent related to its process for producing pigment-grade, titanium-dioxide containing solutions.

    The patent, Altair’s third, offers environmental advantages over existing processes for making the pigments, which are used in fuel cells, batteries, thermal coatings, chemical catalysts and environmental cleanups, according to a news release. Altair said it has filed 12 other patents developed on the foundation of its three issued patents.
