(Materials Research Society Proceedings: Degradation Processes in Nanostructured Materials, 2006)UV- and vacuum UV-assisted photo-oxidation of single-walled carbon nanotube (SWNT) paper occurred with: (1) atmospheric oxygen pressure using low-pressure Hg lamps (ë = 253.7 and 184.9 nm), (2) low oxygen pressure employing ... -
Photoabsorption spectra of gaseous methyl bromide, ethylene dibromide, nitrosyl bromide, thionyl chloride, and sulfuryl chloride
(The American Chemical Society: The Journal of Physical Chemistry, 1978-10-05)The photoabsorption spectra of some molecules of atmospheric interest, CH3Br, BrCH2CH2Br, BrNO, SOCl2, and SO2Cl2, were quantitatively investigated over the wavelength region from 190 to 300 nm at 295 K and were found to ... -
Photoetching and modification of organic polymer surfaces with vacuum UV radiation
(Elsevier: Polymer Degradation and Stability, 1993)Commercially available organic polymer films were treated with radiation from 6·7 × 104 Pa He and Ar plasmas that were made to rotate inside a graphite tube by the application of an auxiliary magnetic field. To investigate ... -
Photoetching and modification of poly(tetrafluoroethylene-co-hexafluoropropylene) polymer surfaces with vacuum UV radiation
(Elsevier: Polymer Degradation and Stability, 2003-03)Films of poly(tetrafluoroethylene-co-hexafluoropropylene) (FEP) were exposed to radiation from 6.7 x 104 Pa He and Ar dc arc plasmas that were made to rotate inside of a graphite tube by the application of an auxiliary ... -
A Photographic insight into the motion of liquid-vapor interface during rapid evaporation of a liquid droplet on a heated surface
(American Society of Mechanical Engineers (ASME), 2001-11)Photographic observations of the boiling phenomena have played an important role in gaining insight into the boiling mechanism. This paper presents a brief historical review of the available literature on the photographic ... -
A photographic study of nucleation characteristics of cavities in flow boiling
(Taylor & Francis, 1995)In the present investigation, the effects of wall superheat and flow velocity on the nucleation characteristics of cavities of different radii have been experimentally determined for flow boiling of subcooled water near ... -
Photography: Making every photon count
(Nature Publishing Group, 1999-12-23)More than 150 years after the invention of photography, the underlying solid-state photochemistry is still being investigated and improved. One aspect of continual importance is the efficiency of the image-recording stage, ... -
