In this study, palladium-modified nickel foam substrate was applied to examine ethanol oxidation reaction (EOR) in 0.1 M NaOH supporting solution. An EOR catalyst was prepared by physical vapour deposition (PVD) of palladium onto Ni foam material. Temperature-dependent kinetics of the EOR were studied over the temperature range: 20-60°C by means of a.c. impedance spectroscopy and cyclic voltammetry techniques. Deposition of a noble metal additive was clearly exposed through scanning electron microscopy: SEM/EDX-supported analysis. Most importantly, this work investigated the effect of pre-deposited fullerene on nickel foam, on the catalytic (EOR) properties of such-produced Ni foam/Pd composite material.

Vitreous floaters are one of the most common complain of ophthalmological patients. The aetiology of floaters includes pathological process (vitreous haemorrhages, injuries, diabetics or uveitis) and also natural age-related changes in vitreous body. Diagnosis and treatment depends on the severity of the symptoms. Process of posterior vitreous detachment requires particularly careful monitoring, because of potential complications such as retinal tears or retinal detachment. Supplementation with anti-glycation and antioxidant substances allows to reduce complains of patients with vitreous floaters.

Carbon nanotubes films have been studied with SEM and TEM. The studied films were obtained using a two step method: PVD process and CVD process. Strongly defected and curled carbon nanotubes containing Ni nanoparticles formed the film with thickness of about 300–400 nm. Observed carbon nanotubes were of lengths from 100 nm to 300 nm and did not stick to each other.
