Multilayer Low Tg Inorganic Glass/Polymer Barrier Films

Vennerberg D., Bemis Company, Inc., US
Conventional high barrier films are produced by coating or laminating inorganic materials to polymeric substrates. While successful at lowering the permeability of the films, several unit operations are required to introduce multiple inorganic barrier layers. [...]

Coatings for next-generation harsh environment systems.

Berger K., DiMaio J.R., Haldeman A.T., Morgan B., Shaughnessy M., Tetramer Technologies, US
From space to oil and gas wells, polyimide coatings and films are used to protect critical components such as fiber optic cables, enameled wires, and sensors in harsh environments. Polyimide materials provide exceptional thermal durability, [...]

Advanced Film Thermal Protectors for Electronic Devices

Wang Y., UCI, US
This advanced thermal protector is based on the patent (U.C. Case No. 2012-130), which provides one-way heat flow function, i.e. enabling heat dissipation from the electronic devices, while preventing outside heat from thermally damaging the [...]

Transparent, Scalable, and Flexible Piezoelectric Pressure Sensors

Vishniakou S., UC San Diego, US
We present a pressure-sensitive ZnO thin-film transistor (TFT) as a potential technology for next-generation touchscreen. We discuss the properties of our devices and propose a structure that could be used to create transparent, scalable, and [...]

Insulator oxide film formation with acid catalyzed hydrolysis of alkoxides in supercritical fluid carbon dioxide

Apt S.D., Brown G.J., Campo A.M., Landis G.R., Wai C.M., Wang J-S., Air Force Research Laboratory, US
Insulator oxide films can be produced by hydrolysis of metal alkoxide precursors in the presence of an acid catalyst in supercritical fluid carbon dioxide(sc-CO2). In this study, a new process has been developed to cover [...]

Nanoparticles: Synthesis and Film Deposition Using a Simple and Fast Centrifuge Sedimentation Method

Brown G.J., Markelonis A.R., Wai C.M., Wang J-S., Air Force Research Laboratory, US
Gold nanoparticles were prepared by reduction of gold cations suspended in sodium bis(2-ethylhexyl)sulfosuccinate (AOT) water-in-hexane microemulsions with another AOT microemulsion containing a reducing agent NaCNBH3. The size of the Au nanoparticles can be controlled by [...]

Robust thin spin-coated silver films with polymer thin layers for SPR image sensor applications

Cho Y-J, Lee M.H., Son J.-H., Sungkyunkwan University, KR
We fabricated thin silver films with thicknesses of 20 nm, 40 nm, and 60 nm on a prism using a spin coating method for SPR image sensor module applications. An aqueous silver ionic complex solution [...]

Silicon and Germanium Nanocrystal Thin Films Prepared Using Innovative Nonaqueous Electrophoretic Deposition

Haag M., Sipe J., Universal Nanotech Corporation, US
As cost effective synthetic routes for producing large quantities of high purity size-specific nanoparticles become fully realized, the next challenge lies in fabricating devices that utilize the unique size-dependent optoelectronic properties inherent in quantum dot [...]

Gels of Carbon Nanotubes and Nonionic Surfactant and High-quality Carbon Nanotube Films Prepared by Gel Coating

Ouyang J., National University of Singapore, SG
Processing of large-scale carbon nanotubes (CNTs) are very important for the application of CNTs in various aspects. Here, we report CNT gels by dispersing CNTs in various nonionic surfactants. High-quality CNT films were prepared by [...]

Detecting CH4 and CO Gases Using Micro-Structural Doping Compound Oxide Films on Si-Substrates

Ding J.-J., Kish L.B., Li Y.F., Ma S.Y., Northwest Normal University, US
Fluctuation-enhanced chemical sensing with commercial gas sensors have already been studied[1-4]. Fig. 1 shows one of the typical fluctuation-enhanced signals of PdxWO3 film sensor. The gas-sensing films used in commercial gas sensors are deposited on [...]
