Controlled fluorination of a-C:F:H films by PECVD of ethylene-hexafluorobenzene mixtures
(Elsevier B.V. Sa, 2008-12-25)
Highly fluorinated plasma polymers are chemically inert,acid resistant and have low friction coefficients, thereby being useful in chemical laboratories and for tribological applications. Here we report the plasma ...
Characterization of Si : O : C : H films fabricated using electron emission enhanced chemical vapour deposition
(Elsevier B.V. Sa, 2008-01-15)
Silicon-based polymers and oxides may be formed when vapours of oxygen-containing organosilicone compounds are exposed to energetic electrons drawn from a hot filament by a bias potential applied to a second electrode in ...
Effects of Different Swimming Exercise Intensities on Bone Tissue Composition in Mice: A Raman Spectroscopy Study
(Mary Ann Liebert, Inc., 2011-04-01)
Objective: Raman spectroscopy was employed to evaluate the effect of different swimming intensities on femoral bone composition in an animal model. Background Data: Intense swimming exercise may affect bone mineralization, ...
Blue cooperative luminescence properties in Yb3+ doped GeO2-PbO-Bi2O3 vitreous system for the production of thin films
(Elsevier B.V., 2006-10-25)
Germanate glasses are of interest for optoelectronic applications because they combine high mechanical strength, high chemical durability and temperature stability with a large transmission window (400 to 4500 nm) and high ...
Transparent and conductive ZnO : Al thin films prepared by sol-gel dip-coating
(Elsevier B.V., 2004-01-01)
Aluminum doped zinc oxide polycrystalline thin films (AZO) were prepared by sol-gel dip-coating process. The sol was prepared from an ethanolic solution of zinc acetate using lithium hydroxide or succinic acid as hydrolytic ...
Continuous Synthesis and in Situ Monitoring of Biodiesel Production in Different Microfluidic Devices
(Amer Chemical Soc, 2012-08-22)
Currently, there is great interest in developing new processes for continuous biodiesel synthesis in order to overcome problems imposed by biphasic reaction and thermodynamic equilibrium, as well as to reduce production ...
Photoinduced hole-transfer in semiconducting polymer/low-bandgap cyanine dye blends: evidence for unit charge separation quantum yield
(Royal Soc Chemistry, 2009-01-01)
Power-conversion efficiencies of organic heterojunction solar cells can be increased by using semiconducting donor-acceptor materials with complementary absorption spectra extending to the near-infrared region. Here, we ...
Disorder effects produced by the Mn and H incorporations on the optical absorption edge of Ga1-xMnxAs:H nanocrystalline films
(Elsevier B.V., 2008-12-15)
The optical absorption edges of nanocrystalline Ga1-xMnxAs:H films (0.000 <= x <= 0.081) prepared by sputtering were analyzed. The influence of Mn and hydrogen incorporations were both investigated. The energy dispersive ...
