Large Scale Manufacture of Electrochromic Glass Plant

In a November 10, 2010 announcement, "Saint-Gobain GSage Electrochromicslass has acquired 50 percent of the equity of the U.S. company SAGE Electrochromics for the large-scale manufacture of electrochromic glass. Activated by a low-voltage current, electrochromic glass adapts its light and heat transmission - and so its tint - to the level of sunlight and the building's ambient temperature, without hindering external visibility. It significantly reduces the amount of energy consumed for air conditioning, heating and lighting, and enhances occupant comfort and well-being. For architects, it creates an aesthetic and efficient alternative to the current and prevalent use of mechanical window shades and blinds which currently dominate the market."

Sage Electrochromics' press release states "Under terms of the agreement, Saint-Gobain will contribute its electrochromic glass intellectual property (IP) to SAGE, and all manufacturing and R&D efforts will be merged. SAGE will manufacture the next generation dynamic glass for both companies' product lines at its facilities in Faribault, Minn. The two companies currently have the most proven electrochromic products on the market, with more than 100 patents and 40 years combined R&D experience. Two senior members of Saint-Gobain's management team - Jean-Pierre Floris and Francois-Xavier Moser - will join SAGE's board of directors."

Microfloat vs. Traditional Glass-Ceramic Manufacturing

"Commercial architects are demanding clear, transparent, smooth, distortion-free and environmentally friendly fire-rated glass-ceramic, because it offers more aesthetically appealing protection. The problem: it's an incredibly difficult and energy-intensive product to make.  Schott, with North American headquarters in Elmsford, N.Y., has found a solution. The company is using an innovative glass-ceramic manufacturing process - called the microfloat process - to produce clear, colorless, transparent and wireles s fire-rated glass-ceramic with a smooth, distortion-free surface. This fire-rated glass-ceramic, Schott Pyran Platinum, is the only glass-ceramic in the world produced using this microfloat process.

The unique mMicrofloaticrofloat process was born out of the microfloat melt tank at Schott Technical Glass Solutions GmbH in Jena, Germany. Schott's microfloat tank differs from common soda lime float tanks in both size and process capability. The microfloat tank, as the name implies, has a smaller output of 20 tons to 50 tons per day compared to large soda lime float tanks, which can produce 400 tons to 1,000 tons per day. However, this smaller output enables the tank to operate at much higher temperatures and create more customized glass-ceramic solutions."

How to Prepare for Expansion into Foreign Markets

This is a two-part article addressing steps that glass company management should take prior to expanding their business into foreign countries.

"Today's economy and construction market have prompted many glass and glazing manufacturers to consider taking on projects in other countries or expanding operations into foreign markets.  While doing business in a foreign country is not uncommon, it requires some homework. Learning more about the foreign country's business and legal climate, employment laws, taxes and insurance issues is critical to assessing the possible risks and values of an overseas venture."

The article recommends several steps for successful business ventures abroad.

Billions of Pieces, Billions of Questions

"In 2004, in a laboratory in England, two researchers placed Scotch tape on a graphite crystal-the same sort of material used to make pencils-and peeled it off. With this comically simple idea, Andre Geim and Konstantin Novoselov managed to isolate, for the first time, a layer of graphene.

The production method may have been low technology, but the Nanotechnologytask of confirming that the layer had been transferred onto a silicon substrate for study was arduous and difficult because all activity was taking place on the atomic scale. For this, these researchers were recently presented with a 2010 Nobel Prize. The pattern of development in nanotechnology follows much the same model today. Making a layer of graphene isn't terribly difficult; but making many of them, of the same size, and controlling how the properties are utilized in a product is a considerable challenge.

In September, the National Center for Manufacturing Sciences (NCMS), an Ann Arbor, Mich.-based consortium of 175 North American companies, released the third in its series of surveys measuring the momentum of the nanotechnology and deployment in the U.S. manufacturing industry.

The data showed that U.S. manufacturers are increasingly using nano-enhanced materials to improve their products, having identified nanotechnology as being vital to competing globally. But among the report's revelations were daunting challenges that include a lack of awareness of nanotechnology's potential advantages, a lack access to the required design tools and training, and a lack of access to capital to fund investment in new technologies."

Thin Films of Nanostructured Polymers with Silver Nanoparticles Kill Bacteria


"Empa (Swiss Federal Laboratories for Materials Science and Technology) researchers have demonstrated how they can adjust process conditions to influence the properties of novel plasma polymer coatings containing silver nanoparticles. Tailor-made films can be generated through a one-step plasma process. The scientists developed these new coatings, which kill bacteria while having no negative effect on human tissue, in the frame of an EU project.

Silver ions are very efficient at killing bacteria, and in contrast to antibiotic drugs, they are effective against hundreds of different bacterial strains thanks to different attacking mechanisms. This makes silver ideal as an antibacterial additive for, e.g., implants and wound dressings. The idea that "a little is good, more is better" cannot be adopted to silver in every case, since higher ion concentrations might also damage human cells and tissues. Therefore, surface coatings need to be made with a therapeutically useful range of silver."

How Do Government Funds Affect Intellectual Property?

The U.S. government is aggressively funding development of alternative energy sources. Their initiatives cover research and development (R&D), manufacturing and construction/ownership of solar energy facilities in the U.S. As companies rush to secure funding it is important to understand that some types of government funding may give government substantial rights to the company's intellectual-property (IP). This article provides an overview of the main sources of government funding (federal funding, tax credits, state funding) and the impact on intellectual-property rights. The Bayh-Dole Act which defines patent right of federally funded inventions made by small business firms and nonprofit organizations (e.g. universities) is also discussed.

Rare Earth Supply Chain - Industry's Common Cause

"Rare earths-minerals, metals and their oxides-have been a looming problem for several years but became a political football recently Open Pit Minewhen China reduced its export quotas for the second half.  Jittery markets responded by upping already rising prices for rare earths, and manufacturers with strategic stockpiles have begun tactical hoarding, a move that analysts warn could drive prices even higher. The cost of rare earths hasn't yet had much of an impact on the pricing of electronic components that use them. But observers see impending shortages for the rare earths used to make the super-strong magnets designed into everything from hard drive heads to smart bombs, the phosphors used in many LEDs and fluorescent lamps, the slurries used for semiconductor polishing, the dopants sometimes used in optical components such as lasers, the magnetic films used for spin-polarized memories and the oxides used in advanced high-k dielectrics."

 Cleantech Funding Falls

"After a strong first half, worldwide venture capital investment in environmentally friendly firms hit a snag, falling 30% in the third quarter to $1.53 billion. The quarter-to-quarter drop is likely due to investor concerns about the slow economic recovery, according to Cleantech Group, the research firm that gathered the statistics. In addition, funding for cleantech companies was down 11% from the third quarter of 2009.

Cleantech Funding

However, the cleantech industry continues to raise more venture money than the biotech and information technology sectors. Within cleantech, technologies related to transportation, biofuels, and the electric grid received the most money, but the largest number of deals was at firms focused on energy efficiency. Cleantech Group President Sheeraz Haji says energy-efficiency deals are attractive because they require small amounts of capital and offer fast payback times."

Japanese Researchers Directly Observe Hydrogen Atom

Japanese researchers announced that they have succeeded in directly observing a hydrogen (H) atom for the first time in the world.

H atom has an atomic number of 1 and, with a diameter of about 0.1nm, it is the smallest atom of all the elements. The achievement is expected to accelerate the research and development of technologies to store hydrogen, silicon devices and so forth.

The research results were published Nov 5, 2010, on the online edition of the English magazine "Applied Physics Express (APEX)" published by the Japan Society of Applied Physics (JSAP).

The results were achieved by a research group led by Yuichi Ikuhara and Naoya Shibata, professor and assistant professor, respectively, at the Institute of Engineering Innovation, School of Engineering, the University of Tokyo, in collaboration with Tomohiro Saito, researcher at the Japan Fine Ceramics Center (JFCC), and Jyunko Matsuda, researcher at Japan's National Institute of Advanced Industrial Science and Technology (AIST).

They observed a vanadium hydride (VH2) crystal, which is a hydrogen absorbing metal, by using a newly-developed high-resolution electron microscope.

New Antibacterial Material for Bandages, Food Packaging, Shoes

Chunhai Fan, Qing Huang, and colleagues explained that scientists in the United Kingdom first discovered the material, known as graphene, in 2004. Since then, the race has been on to find commercial and industrial uses for graphene. Scientists have tried to use graphene in solar cells, computer chips, and sensors. Fan and Huang decided to see how graphene affects living cells.

So they made sheets of paper from graphene oxide, and then tried to grow bacteria and human cells on top. Bacteria were unable to grow on the paper, and it had little adverse effect on human cells.

"Given the superior antibacterial effect of graphene oxide and the fact that it can be mass-produced and easily processed to make freestanding and flexible paper with low-cost, we expect this new carbon nanomaterial may find important environmental and clinical applications," the reports states.
