Time-related wettability characteristic of acrylic resin surfaces treated by glow discharge
STATEMENT OF PROBLEM: Adhesion and cohesion have important roles in denture retention, and attempts have been made to improve the wettability of the acrylic resin material by surface treatments. PURPOSE: This study examined ...
FTIR characterization of Ru/SiO2 catalyst for ammonia synthesis
Carbon monoxide adsorption on a Ru/SiO2 catalyst was followed by IR spectroscopy to investigate the active sites. Using this catalyst, ammonia synthesis was achieved at 3508C in an N2/H2 gas mixture (N2/H2 < 3 : 1) for ...
Sorption studies of Cs+ and Ba2+ cations on magnesite
The adsorption behavior of Cs+ and Ba2+ cations on magnesite has been studied as a function of time, cation concentration and temperature, utilizing both the radiotracer method and X-ray photoelectron spectroscopy (XPS). ...
Determination of electron affinity of phenyl radical by dissociative electron attachment technique
(John Wiley & Sons, 1993-03)
Analysis of polymers using evolved-gas and direct-pyrolysis techniques
(Royal Society of Chemistry, 1994)
Thermal analysis of polystyrene, poly(p-methylstyrene) and poly(α-methylstyrene) has been carried out using evolved-gas analysis by infrared and mass spectrometry, and direct-pyrolysis analysis by mass spectrometric ...
A photoelectron spectroscopic investigation of conducting polypyrolle-polyamide composite film
X-ray photoelectron spectrum of the electrochemically prepared polypyrrole and polypyrrole-polyamide composite films exhibit an additional strong high binding energy peak at 402.0 eV corresponding to N+ moieties. Intensity ...
UV-Vis, IR, and XPS analysis of UV induced changes in PVC composites
PVC undergoes a high degree of dehydrochlorination when exposed to energetic photons. The released HCl (acid), however, can be trapped if a suitable trapping material (base) is also enclosed within the solid matrix as a ...
Pyrolysis mass spectrometric analysis of styrene-butadiene block and random copolymers
Direct pyrolysis mass spectrometric analysis of a styrene-butadiene-styrene block copolymer indicated that thermal decomposition of each block shows a resemblance to the related homopolymer, giving a possibility of ...
XPS and FTIR characterization of manganese ions deposited on alumina
By application of XPS and FTIR spectroscopy of adsorbed CO the effect of preparation conditions on the state and localization of manganese ions deposited on h-Al2O3 is studied. Both Mn21 and Mn31 ions are observed on the ...
A study of the chemiionization reactions of Ca, Sr and Ba with O2(X 3Σ-g)
Chemielectron and chemiion spectra resulting from the reactions of effusive beams of Ca, and Sr and Ba (in their ground 1S states) with ground state molecular oxygen O2(X 3Σ- g) have been recorded using electron spectroscopy ...
