  of the protective liner from a bumper sticker or. band-aid. The liners are often silicone-coated. Silicones have very low surface energies, in the 22-24 dynes/centimeter. (common units of surface energy) range, compared with most PSAs, which are between 30 and 36 dynes/cm. The. silicone-coated liner presents...
• Physical properties of CdS/ITO thin films growth by CBD technique with substrate oscillating agitation
  in order to agitate the substrate during deposition, meanwhile the chemical solution is heated and/not agitated. The deposited films were characterized on their morphology, on the band gap energy, and on thickness. The implemented novel technique for substrate oscillation has shown to improve...
• Wired 8.09: Bright Switch
  Already, labs in 27 countries are pursuing research into photonic band-gap crystals. In the US, Darpa has issued millions in research grants. At least eight government-funded facilities and more than 40 universities are involved, along with corporations such as NEC, Rockwell, Lucent, and Agilent...
• Hydrogen power from the sun
  charge-transfer properties and corrosion stability, making it a likely candidate for cheap and long-lasting solar cells. However, ultraviolet light comprises roughly 5% of the solar spectrum energy, so it was necessary to move the materials band gap into the visible spectrum. It turns out doping the TiO2...
• EL Technology Overview White Paper
  of having a band gap large enough to emit. visible light without absorption. This limits the class of possible materials to large band gap. semiconductors (Eg > 3.0 eV) and insulators. The classical CRT phosphor host materials are the. II-VI compounds and the rare earth oxides and oxysulfides...
• Liquid Crystals - Preface
  important addition is a quantitative discussion of the optical properties and fundamentals of one-dimensional photonic crystal band structures. Dispersion is added to fill in an important gap in most treatments of cholesteric liquid crystals. In Chapter 6, we explore the fundamentals of liquid crystals...
• Optimization of Fusion Splice Process for High Numerical Aperture Coupler Fiber and Erbium Doped Fiber (.pdf)
  980/1600 WDM coupler fiber, EDF, Fusion Splice Loss. In a typical erbium doped fiber amplifier (EDFA), a wavelength-division-multiplexing (WDM) fiber coupler is used as an energy and signal combiner to transmit the signal energy and deliver the optical energy from a laser diode (LD) to the erbium...
• What is Hot in IR Micro Vision
  (np/n0 -1),. (5). with P0 being the parameter connected to the band gap structure and other fundamental properties of. material. There are varieties of ways to provoke luminescence in semiconductors from which. electroluminescence and photoluminescence are only two major examples to name...
• Here come metal-oxide nanotubes
  if we can coax them into nanotubes with dimensions comparable to single-walled carbon nanotubes, we will have a range of useful properties," says Nair. Controlling dimensions of nanostructures is critical because properties such as electronic band-gap largely depend on dimensions. Dimension control...
• MICRO: Optimizing polymers to increase pellicle lifetime and transmission for 157-nm lithography
  . Using Vacuum Ultraviolet Spectroscopic Characterization for Materials Design. Vacuum ultraviolet (VUV) spectroscopy, including both transmission and reflectance measurements, has become an established technique for electronic structure studies of large band-gap, insulating materials...
