Analysis of Fe nanoparticles using XPS measurements under d.c. or pulsed-voltage bias
The impact of solution exposure on the charging properties of oxide coatings on Fe metal-core oxide-shell nanoparticles has been examined by sample biasing during XPS measurements. The Fe nanoparticles were suspended in ...
Collagen-chitosan scaffold modified with Au and Ag nanoparticles: synthesis and structure
(Elsevier B.V., 2016)
Nowadays, the dermal biomimetic scaffolds are widely used in regenerative medicine. Collagen-chitosan scaffold one of these materials possesses antibacterial activity, good compatibility with living tissues and has been ...
Effect of solvent refractive index on the surface plasmon resonance nanoparticle optical absorption
Optical properties of plasmon coupled silver and gold nanoparticles were studied as a function of the refractive index of the surrounding medium. Our studies confirmed that the effect of changes in the refractive index of ...
Preparation of Au and Au-Pt nanoparticles within PMMA matrix using UV and X-ray irradiation
Au and Au-Pt alloy nanoparticles are prepared and patterned at room temperature within the PMMA polymer matrix by the action of 254 nm UV light or X-rays. The polymer matrix enables us to entangle the kinetics of the ...
X-ray induced reduction of Au and Pt ions on silicon substrates
Prolonged exposure to X-rays of HAuCl4, PtCl4 and their mixtures, deposited from an aqueous solution onto a silicon substrate, causes chemical reduction of the metal ions to their metallic states. The corresponding oxidation ...
Photopatterning of PMMA films with gold nanoparticles: diffusion of AuCl4-ions
Photopatterning of poly(methyl methacrylate) (PMMA) films is performed by UV irradiation of the polymer films containing uniformly distributed AuCl 4 - ions. The process reduces the gold ions and leads to production of Au ...
