graphite, is a perspective unit for the construction of these materials and a good model system for the investigation of their interaction with lithium. Particularly, it has been shown that adsorption of lithium on both graphene sides increases the specific capacity almost twice as compared to graphite [ 4 ]. In a nanostructured material, lithium can adsorb on the surface and intercalate between graphene layers or into the graphene-metal interface space of a multicomponent system. X-ray photoelectron spectroscopy (XPS) can help to understand these processes by studying

Abstract

In this study, povidone-iodine (PVP-I) has been formulated as a topical spray to produce a thin film for the controlled release of I2. By means of experimental design, 27 formulations containing glycerol, ethanol, PEG 400, copovidone and HFA 134a as a propellant were prepared. The pH values of all formulations were in the range of 6-7. The viscosity was within the range of 11.9-85.9 mPa s. The surface tensions were 20.3 to 24.6 mN m-1 and the contact angles were between 19.3 and 38.7°. The assays for the iodine contents were within acceptable range (80-120 %). X-ray photoelectron spectroscopy analysis revealed the ionized form of iodine was much higher than the unionized form. The MIC and MBC values of the PVP-I sprays against Staphylococcus aureus, S. epidermidis and Pseudomonas aeruginosa were higher than that of commercial PVP-I solution. The cytotoxicity study confirmed that the PVP-I spray had lower toxic effects on keratinocytes and fibroblasts compared to the commercial PVP-I solution. The formulation containing 59 % ethanol, 18 % copovidone and 12 % PEG 400 showed good antibacterial activity.

coexist in these slags. Low slag basicity and low oxygen potential lead to the increase in divalent chromium oxide, instead of trivalent chromium oxide. Pretorius et al. [ 10 ] calculated the chromium valence states in CrO x –SiO 2 , CaO–CrO x –SiO 2 , and CaO–SiO 2 –Al 2 O 3 –CrO x systems and found that the valence states of chromium were mostly affected by the oxygen partial pressure. In recent years, X-ray photoelectron spectroscopy (XPS) was applied to valence state detection in metallurgical slag [ 11 , 12 , 13 ]. XPS can carry out not only qualitative analysis

Chapter 13 Michael F. Hochella, Jr. AUGER ELECTRON AND X-RAY PHOTOELECTRON SPECTROSCOPIES 1. INTRODUCTION This chapter deals with the two most widely used surface sensitive spectroscopies today, x-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES). Since these two methods were introduced for general laboratory use around 1970, they have shown remarkable applicability to scientific investigations in many disciplines, and a number of excellent reviews already exist in the li terature (for XPS, see e.g. Riggs, 1975, Briggs and Seah
