Systematic and collaborative approach to problem solving using X-ray photoelectron spectroscopy

Highly sensitive nitric oxide detection using X-ray photoelectron spectroscopy.

Nitric oxide (NO) is important physiologically as a gaseous messenger in the central nervous system;1 its level is also associated with several disease states.2 The concentration of NO in these cases is in the nanomolar range; therefore accurate and direct detection of NO at these levels is important. NO is also a decomposition product of several explosives3 so detection of trace amounts of exp...

X - Ray Photoelectron Spectroscopy of Silicate Glasses

X-ray photoelectron spectroscopy (XPS) is a powerful technique capable of providing unique information about the structural chemistry of glasses. However, inappropriate procedures for the preparation of sample surfaces or the lack of reliable methods to overcome electrostatic charging effects during analysis of dielectric materials can cause spurious features to be introduced or intrinsic featu...

Surface analysis of dental amalgams by X-ray photoelectron spectroscopy and X-ray diffraction.

OBJECTIVES It is important to characterize the surface of dental amalgam in order to understand the process of mercury release from amalgam restorations in the oral cavity. The mercury evaporation occurs not only from the newly made restoration but also from the set material. METHODS The surfaces of four different types of amalgams, which had been well set, were analyzed with X-ray photoelect...
