“…Curve fitting was performed with the 'Googly' program that accounts for both intrinsic and extrinsic contribution [12,13] on the analyzed spectra. The energy scale of curve-fitted regions and results from curve fitting ( Table 1) were converted to binding energie (BE) and referenced to internal standard, reference compound and data base, [14,15] also available online.…”

The finite electrosynthesis, requiring 20 voltammetric cycles at neutral pH, of insulating poly(o-aminophenol) (PoAP)and its polymerization mechanism and chemical structure up to the outermost surface were reported in previous work. By reducing the number of voltammetric cycles, XPS, atomic force microscopy, and electrochemical experiments were here confined to partially grown PoAP to better understand the role of the platinum surface on the initial adhesion mechanism and polymer growth. XPS results from reduced number and conventional 20 cycles show that PoAP composition is the same at any cycle. The main differences imaged by atomic force microscopy between 1, 5, and 20 cycles are on the amount of 'small-sized particles' adsorbed on platinum prone to 'fill' the empty sites. The progressive filling of the platinum sites with cycles was also proved by electrochemical test with potassium-ferricyanide. These new results add valuable information, which sustain previous hypotheses on the growth process of PoAP chains, their composition, and lateral alignment. Some questions, concerning the identification of PoAP anchoring bonds on platinum, lateral H-bonds with water, and inter-chains interactions, still remain unanswered and will be further addressed by the employment of new advanced means of investigation already in progress.

“…Under these conditions, the instrumental contribution to line-width is kept constant and the measured FWHMs (full width at half maximum) of Au 4f 7/2 (84.0 eV) and Cu2p 3/2 (932.7 eV) signals used for calibration purposes were 1.3 and 1.6 eV, respectively. The peaks were analysed using a curve-fitting program, GOOGLY, which was fully described in previous works, [33,34] and their assignment was referred to in the literature and XPS database available online. [35] The sample substrates were mounted on the sample holder using a double-sided adhesive copper tape and then transferred to the analysis chamber where the vacuum was always better than 5 Â 10 -9 mbar.…”

Polypeptides can form helical fibres in aqueous media: potentially useful for the production of biocompatible fabric and yarns. A previous work has shown that fibre formation occurs readily with elastin-like polypeptides constructed from hydrophobic amino acids, such as valine, glycine and leucine. However, elastin-like polypeptides, when suspended in methyl alcohol, are observed to form globules and 'string of bead' structures. Thus, it seems probable that the interface energy is important. Interface energy is minimised by the formation of bonds extending from one phase to the other: a phenomenon that is central to adhesion science. We have looked for evidence of such bonding using XPS to study structures formed by poly(ValGlyGlyLeuGly). The structures formed were first characterised by atomic force microscopy. Differences were found between structures and spectra formed in either water or methanol. No evidence for the presence of unique bonds characterising the interface was found, but evidence was found for the influence of a water environment on the internal structure, suggesting that it is the increase in intermolecular bonding opportunities associated with the influence of water on the growth of fibres that is the thermodynamic driver for the observed transformation into fibre deposits.

“…The acquired XPS spectra were analyzed using a curve-fitting program (Googly) that has been fully described previously. [31,32] Peak areas were converted to composition in at % using established procedures and the appropriate sensitivity factors (SF). [33] The criteria adopted for data elaboration were based on comparative studies, starting with the analysis of the untreated sample; literature data were referenced [33,34,19,35] and the NIST standard reference database was available online.…”

The aim of this study was to determine the effect of UV-C irradiation on the Turkey oak wood surface (Quercus cerris L.). In order to compare the effect of irradiation, both untreated wood samples and those treated with steam and heat were analyzed. The steam treatments were carried out in an autoclave at 130 °C; samples were then heated in an oven for 2 h at 180 °C. The physical and chemical changes brought about in the untreated and treated wood samples by the UV-C light were monitored by colorimetry (color changes), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) (chemical composition) and scanning electron microscopy (SEM) (microstructure and morphology). A detailed analysis of the results indicates that the UV-C treatment caused irreversible changes in both the chemical composition and morphology of the wood samples via photooxidation and photodegradation processes. Depending on the type of pre-treatment used, these processes affected the wood samples differently
