Cutting Edge Technology Gets Even Sharper

"Disposable razor blades could become a thing of the past if scientists at Gesellschaft für Diamantprodukte mbH (GFD) have their way. The German high-tech company has developed a super-sharp razor blade made of industrial diamDiamazeonds that could last more than 1,000 times longer than today's conventional blade. The technological breakthrough achieved by GFD employs two specialized processes: the nanocrystalline diamond coating of a carbide blade followed by the plasma sharpening of the blade. To manufacture such a razor blade, a nanocrystalline diamond coating is first applied to a carbide blade, then the minute, jewelled layers are polished by an innovative plasma sharpening process developed by the GFD researchers. The blade is polished until the cutting edge is sharpened to only a few nanometers, therefore consisting of merely a few atoms. This process manages, for the first time, to combine the hardest material in the world with the sharpest possible cutting edge."

3M to Begin High-Volume Production of 3M™ Ultra Barrier Solar Film
October 15, 2010

"3M today announced the expansion of its manufacturing facility for its 3M Ultra Barrier Solar Film. As a key component supplier to the solar industry, this expansion will support the growing demand for high efficiency flexible PV modules. The majority of the facility expansion, located in Columbia, Missouri, is scheduled to be completed in 2011.

'3M once again demonstrates the value it brings to the rapidly expanding renewable energy sector by bringing our high-performance Ultra Barrier Solar Film to commercial-scale production," said Derek DeScioli, Business Development Manager for the 3M Renewable Energy Division. "3M is a recognized leader in ultra barrier film technology, and we are committed to accelerating our efforts to support the scale-up of our thin film manufacturing customers.'

Designed to address the needs of flexible thin film solar manufacturers, 3M Ultra Barrier Solar Film acts as a replacement for glass with high light transmission, superb moisture barrier performance, and excellent weatherability. Compared with glass-glass modules, large area, light weight flexible PV modules manufactured with 3M Ultra Barrier Solar Film can achieve significantly lower balance of systems (BOS) costs by requiring less installation time, removing the need for metal racking, and reducing logistics expenditures. 3M Ultra Barrier Film also enable lower module manufacturing costs by allowing manufacturers to commercialize large area modules, effectively reducing fixed costs associated with module manufacturing, assembled in a continuous roll-to-roll process."

Toshiba Unveils World First 3D LCD TVs without Dedicated Glasses

Toshiba
October 4, 2010, Tokyo

"Toshiba Corporation today unveiled the world's first LCD TVs that offer comprehensive 3D capabilities without any need for dedicated glasses. The new 'Glasses-less 3D REGZA GL1' series offers two models with screen sizes specifically designed for personal use: the 20-inch 20GL1 and the 12-inch 12GL1. Both TVs will be available in Japan from the end of December.


The new Glasses-less 3D REGZA GL1 series employ an integral imaging system and perpendicular lenticular sheet that can display natural and smooth high quality 3D images. A lenticular sheet is an array of lenses that transmits images in a horizontal plane. The sheet is semi-circular in profile. Toshiba's technology simultaneously delivers nine parallax images to the LCD panel and controls and optimizes light emission and direction from the center, right and left of the screen to secure a wide viewing angle. The result is optimized display of high quality 3D images whatever the position and angle to the screen of the viewer. This technology is the recipient of the 21st Century Invention Prize for 2010, one of the National Commendations for Invention, from the HATSUMEI KYOKAI, Japan Institute of Invention and Innovation."

DelSolar and IBM Sign Joint Agreement to Develop Solar Cell Technology

"TAIPEI, September 27, 2010 - DelSolar Co., Ltd (3599.TW) announced today that it has signed an agreement to jointly develop compound thin film solar cells with IBM (NYSE:IBM) aimed to surpass next generation thin film solar cell technology and result in commercial production. The collaboration includes leveraging DelSolar's existing expertise in photovoltaic ("PV") technology and process as well as IBM's advanced semiconductor technology and materials science know-how. "

"This agreement is a significant step in the progress of our effort to create efficient solar cells using earth abundant materials with novel processes" said T.C. Chen, Vice President of Science and Technology IBM Research. "We already have an excellent collaboration with Tokyo Ohka Kogyo Company LTD. ("TOK") for developing manufacturing tooling and the chemistries required for this technology. Recently IBM demonstrated record solar cell efficiencies using a copper zinc tin sulfur selenide (CZTS) material. This new collaboration between DelSolar, TOK, and IBM now puts us firmly on the path to commercially viable technologies and processes for solar cells that could bring us closer to grid parity."

"Thin film solar cell technologies have been based earlier upon amorphous silicon, CdTe, and CIGS. This new technology is based upon inexpensive , earth abundant components, thereby circumventing the need for cadmium which is toxic, or materials whose availability may be questionable for the large volume growths anticipated in the future (indium or tellurium)."

Nanotubes: Conductors to Semiconductors


Nanotube Single-walled nanotubes (SWNT), which are rolled-up sheets of graphene, come in may forms (chiralities) depending on how they are rolled.  Some are semiconduting and some are highly conductive metallics.  Metallic carbon nanotubes show great promise for power transmission.

Rice University physicist, Junichiro Kono and his team have shown that magnetic fields can change metallic carbon nantubes to semiconductors by changing the band gap.  Thus, by changing the magnetic fields, you can switch between the two states.  This opens up a whole new field of applications for nanotubes.

China Halts Shipments to U.S. of Tech-Crucial Minerals

"A nasty trade dispute appears to have prompted Chinese customs officials to block shipments of rare earth minerals to the U.S.

The move underscores a deepening U.S. vulnerability because of its dependence upon China for tech-crucial rare earth minerals (also known as rare earth elements). Small but significant amounts of the minerals go into creating everything from PCs and cellphones to wind turbines and hybrid cars, as well as U.S. military technologies such as missile guidance systems.

This latest news came from three rare earth industry officials cited by the New York Times. The officials spoke on the condition of anonymity for fear of backlash from China.

China currently controls about 97 percent of rare earth production, and has the only facilities capable of processing rare earth minerals after they have been mined. Rare earth minerals are not exactly rare, but the mining and refining processes can be costly and time-consuming.


Official Chinese plans have called for China to reduce rare earth mineral exports to meet its own rising industrial demands. That already indicated to many industry experts that countries such as the U.S. would have to find alternate supplies soon.

U.S. rare earth companies have begun looking to reopen old mines and search for new deposits, but industry experts say that relaunching an independent U.S. supply chain could take 15 years. 

The latest Chinese action follows a similar move last month, when China halted shipments to Japan during a political dispute over Japan's arrest of Chinese fishermen. Among the affected Japanese companies was Toyota, maker of the popular Prius hybrid cars which incorporate the rare earth element neodymium, among others."

Surface Modification of Polymers by Vapor Deposition


In CVD polymerization, the monomers are deposited on the surface from the vapor phase and polymerized on the surface.  The CVD films conform to the surface with uniform thickness and when polymerized by electron, plasma, or UV, the surface may have different properties than the underlying base material.  This article focuses on two CVD polymerization methods, namely initiated CVD and oxidative CVD methods.  Selected applications of the technology are presented, with references.  -DMM

Flexible Graphene Memristors

October 2010, By Prachi Patel, IEEE Spectrum

"South Korean researchers have recently made a flexible nonvolatile memory based on memristors-fundamental electr
Memristorsonic circuit elements discovered in 2008-using thin graphene oxide films. Memristors promise a new type of dense, cheap, and low-power memory and have typically been made using metal oxide thin films. The new graphene oxide devices should be cheaper and simpler to fabricate-they could be printed on rolls of plastic sheets and used in plastic RFID tags or in the wearable electronics of the future.

"We think graphene oxide can be a good candidate for next-generation memory," says Sung-Yool Choi, who leads flexible devices research at the Electronics and Telecommunications Research Institute in Daejeon, South Korea. Choi and his colleagues reported their device last week in Nano Letters.

Memristors change their resistance depending on the direction and amount of voltage applied, and they remember this resistance when the voltage is removed. Most memory types store data as charge. But memristors would enable what's called a resistive RAM, a nonvolatile memory that stores data as resistance instead of charge.

Although the idea for memristors was first proposed in 1971, Hewlett-Packard made the first practical device only two years ago and plans to commercialize the technology within three years. HP's design consists of two arrays of parallel wires arranged perpendicular to each other with a titanium dioxide layer sandwiched in between. Each cross point is a memristor."

The Next Step for Green Electronics: Think Thin Film

October 8, 2010, By Micahel Kanellos, Greentech Enterprise

Chiba, Japan -- Electronics manufacturers have taken fairly impressive strides in increasing their energy efficiency in recent years. Some classes of components are already in the 80-to-90-percent efficiency range.

Green ElectronicsSo what will they do for an encore? Take out the bulk.

The flexible organic light emitting diode (OLED) display in the video below was one of the more impressive demos at Ceatec, the large technology trade show taking place outside of Tokyo. (I'm chairing the "Best of Show" committee.) It measures 0.3 millimeters thick, but it can play video in color. If you're looking for Harry Potter-like moving newspapers, here's your answer.

The screen is experimental, but if the sizes can be increased and the cost can be lowered a la Moore's Law, one can imagine how this technology could put a dent in demand for raw and industrial materials like copper, resins, and glass. Lower demand for these kinds of materials would in turn lower the amount of emissions from mining, transportation and production.

Small Lightweight Night Vision Devices


Commercial night vision devices use electron tube technology necessitating high voltages.  The new devices use organic light-emitting diode technology.  The structure is simple: it consists of a photodetector connected in series with an LED.  When operating, infrared photons are converted to electrons in the detector and these electrons are injected into the LED generating visible light.  The size and weight of the devices hold the potential to be incorporated in everyday devices such as cell phones or standard eyewear.  -DMM

Producing Circuit Boards with Plastic

October 20, 2010, Semiconductor Online

"There is a large growth market for flexible circuits, RFID antennas and biosensors on films. Researchers from the Fraunhofer Institute for Surface Engineering and Thin Films IST are presenting a new technology at K 2010, the international trade fair for plastics and rubber (Hall 3, E91): the experts can now apply conductive metal circuits to plastic substrates in a process that is energy- and material-conserving and thus more sustainable.

Flexible circuits can be found in many devices where space and Plastic Circuit Boardweight considerations are dominant in the design of electronics: in cars, in cameras and video equipment, in mini-computers for athletes or in inkjet printers. And the market continues to grow: according to the business consultancy Frost & Sullivan, sales in this area will grow to more than $16 billion by the year 2014.

At K 2010, the trade fair for plastics in Düsseldorf, Germany, scientists from the IST in Braunschweig will unveil a new reel-to-reel technology for the production of flexible circuits and biosensors; the new technology is known as 'P3T', which is shorthand for 'Plasma Printing and Packaging Technology'. The benefits: P3T involves considerably fewer process steps than existing processes, and it conserves raw materials. Unlike previous methods, the researchers do not start with a polymer film metalized over its entire surface from which excess metal is then removed to create the circuits. Instead, to produce flexible circuit boards, they apply circuits made of copper to the film that serves as substrate. In the case of biosensors, palladium is used. They use plasma at atmospheric pressure and galvanization instead of vacuum-pressure and laser-based methods to achieve inexpensive and resource-efficient production."
