  • Publication number: 20090308550
    Abstract: A method is described for separating pin chips from a wood furnish of wood chips, pin chips and fines mixture. In the method, the wood chips are separated from the pin chip and fines mixture and treated with a surfactant to lower the interfacial surface tension between the pin chip and the fibers. The resulting treated pin chip and fines mixture is then mechanically separated into the individual pin chip and fines fraction.

  • Publication number: 20090239333
    Abstract: A low-cost and efficient process producing improved organic electronic devices such as transistors that may be used in a variety of applications is described. The applications may include radio frequency identification (RFID) devices, displays and the like. In one embodiment, the improved process is implemented by flash annealing a substrate with an energy having wavelengths ranging from about 250 nm to about 1100 nm or higher. In this flash annealing process energy having wavelengths from about 250 nm to about 350 nm or higher is substantially prevented from irradiating the substrate.
