Researchers at Rensselaer Polytechnic Institute have developed thin, flexible energy storage devices consisting of more than 90 percent cellulose. The paper is infused with aligned carbon nanotubes (electrodes), and an electrolyte (e.g. an ionic liquid). The technology allows to fabricate batteries, supercapacitors, or devices which combine both functions. According to the press release, the devices can [...] The NewScientist is reporting on colloidal photonic crystals consisting of dispersions of magnetic iron oxide particles with a charged surface coating, developed by Yadong Yin and colleagues at the Department of Chemistry at University of California, Riverside. Cartamundi, Europe’s largest manufacturer of playing cards and card games, and Thin Film Electronics, developers of printed organic memory devices, have entered into a commercial License Agreement and a joint R&D Program. Cartamundi will use Thinfilm’s patented technology and will now enter into a joint R&D project with the objective to include memory capabilities for the development, [...] Solvay, through their specialty polymer subsidiary Solvay Solexis, and Thin Film Electronics have announced plans to jointly develop materials for printed memory applications. The joint development agreement will build on Thinfilm’s intellectual property for soluble memory materials, as well as extend Solvay’s intellectual property for functional polymer materials. Under the agreement, Solvay Solexis could acquire certain [...] CNET News is reporting on the world’s first truly flexible OLED display fabricated by Sony. According to Pink Tentacle The 2.5-inch prototype display supports 16.8 million colors at a 120 x 160 pixel resolution (80 ppi, .318-mm pixel pitch), is 0.3 mm thick and weighs 1.5 grams without the driver. The prototype, as well as technical details [...] According to a new report by NanoMarkets, the market for OLEDs used in displays and lighting applications is expected to reach $10.9 billion ($US) by 2012 and grow to $15.5 billion by the year 2014. The report discusses the use of OLEDs for mobile devices, flexible/rollable displays, and lighting applications. Polymer Vision (Eindhoven, NL) has announced its cooperation with Innos (Southampton, UK) to manufacture rollable displays: Following 10 years of research, Polymer Vision has spent the past three years processing displays in its own pilot facility in Eindhoven to develop the technology to maturity. Polymer Vision and Innos will together transfer the process technology and finalise [...] Polymer Vision, who presented the first functional device with a rollable display at IFA 2005, have announced their spin-out from Philips: Philips™ Incubator activity Polymer Vision will become an independent company – Polymer Vision Ltd., focusing on products for the rollable display market. Technology Capital has invested €21 million in the company and will become the [...] Plastic Logic announced that it has raised $100 million to build a factory for flexible active matrix display modules in Dresden (Germany). To fund this comprehensive commercialization program, Plastic Logic has completed a first closing of $100 million of equity finance led by Oak Investment Partners and Tudor Investment Corporation. Existing investors Amadeus, which led the [...] Takeo Someya and coworkers at the University of Tokyo have created a flexible sheet comprising organic TFTs that inductively charges electronic gadgets placed on its surface. According to this Technology Review article, the system is designed in a way that overcomes the limitations of common induction schemes. Traditional induction systems can only spread small amounts of power [...] Instead of the usual rubbed polyimide alignment layers, they use the in-situ photopolymerization of alkyl acrylate monomers in the presence of nematic liquid crystals to provide a cellular matrix of liquid crystalline droplets in which the chemical structure of the encapsulating polymer controls the liquid crystal alignment. “Small changes in the chemical nature of the polymer will [...] Bi-stable metal sheets might be useful as substrates for rollable screens (e.g. electronic newspaper). The ‘dimpled’ copper-alloy structures are apparently cheap to produce from a single sheet of metal. George Malliaras and coworkers at Cornell created a novel type of organic diode with an “ionic junction” by laminating together layers of an anthracene derivative containing free positive ions and a ruthenium, complex containing negative ions. When the two are joined, ions diffuse across the junction creating a difference in energy levels that facilitates [...] Gizmag is reporting on SiPix and SmartDisplayer’s recently announced payment card with a flexible electrophoretic display, which enables cardholders to generate and display a dynamic passcode for one-time use. The application subsequently landed the companies the Display Application of the Year Award from the Society for Information Display (SID). [...] The Cambridge Evening News is reporting that Amazon, the world’s biggest bookseller, is in talks with Cambridge company, Plastic Logic, about the end of books as we know them. [...] |
