Characterization of gold nanoclusters synthesized on carbon nanotubes film: Evaluation of the size distributions by means of X-ray photoelectron spectroscopy

Effect of thermal treatments on sputtered silver nanocluster/silica composite coatings on soda-lime glasses: ionic exchange and antibacterial activity

“…The spectrum of the as sputtered coating shows a loss of feature with respect to that of pure silver (Ag Ref, deposited by thermal evaporation). Its valence band width is around 1.6 eV, in excellent agreement with ( Speranza et al 2009, Minati L et al 2008, Minati L et al 2010, Wertheim GK et al 1983 on silver nanoparticles embedded in a soda lime glass.…”

Mild hydrothermal treatment to prepare highly dispersed multi-walled carbon nanotubes

“…Figure 1b presents the high-resolution C 1s spectra of pristine MWCNTs and the modified MWCNTs obtained by hydrothermal treatment in different KPS concentration. On the basis of the literature reports [7,[15][16][17][18], the overall C 1s peak was fitted by a superposition of five peaks (the K 2p peaks at 293.2 eV and 295.9 eV were taken into account during fitting, because it affected the area of C 1s spectrum). The main peak at 284.…”

Photoreduction Kinetics of Sodium Tetrachloroaurate under Synchrotron Soft X-ray Exposure

“…Metal nanoparticles have attracted significant interest because of their potential use in applications such as microelectronics, photonics, catalysis, and biochemical sensors. − Gold nanoparticles can be generated with control over size and shape via a number of techniques. These include chemical reduction from an aqueous tetrachloroaurate solution, , X-ray , and γ-ray irradiation of a solid gold salt, chemical synthesis of size-specific clusters (e.g., 55-atom Au), direct deposition of size-selected clusters onto a substrate, and laser ablation of a metallic gold disk. − Previously, we have described the kinetics involved in nanoparticle formation in solution via laser ablation of gold in pure water and solutions of sodium dodecylsulfate .…”
