detachment from linoleum surface: influence of liquid flow rate and cleaner type.

The aim of this research is to analyse the impact of surface cleaner type and hydrodynamic flow on bacterial detachment. For that purpose, a new liquid flow chamber was constructed and applied. In experiments, was grown on linoleum surfaces that are used in health care institutions.

Microwave-Assisted Synthesis of Pt/SnO for the Catalytic Reduction of 4-Nitrophenol to 4-Aminophenol.

In this study, we present a new approach for the synthesis of Pt/SnO catalysts using microwave radiation. Pt(IV) and Sn(IV) inorganic precursors (HPtCl and SnCl) and ammonia were used, which allowed the controlled formation of platinum particles on the anisotropic SnO support. The synthesized Pt/SnO samples are mesoporous and exhibit a reversible physisorption isotherm of type IV.

Solid-State Dispersions of Platinum in the SnO and FeO Nanomaterials.

The dispersion of platinum (Pt) on metal oxide supports is important for catalytic and gas sensing applications. In this work, we used mechanochemical dispersion and compatible Fe(II) acetate, Sn(II) acetate and Pt(II) acetylacetonate powders to better disperse Pt in FeO and SnO. The dispersion of platinum in SnO is significantly different from the dispersion of Pt over FeO.

Rheological, Microstructural and Thermal Properties of Magnetic Poly(Ethylene Oxide)/Iron Oxide Nanocomposite Hydrogels Synthesized Using a One-Step Gamma-Irradiation Method.

Magnetic polymer gels are a new promising class of nanocomposite gels. In this work, magnetic PEO/iron oxide nanocomposite hydrogels were synthesized using the one-step -irradiation method starting from poly(ethylene oxide) (PEO) and iron(III) precursor alkaline aqueous suspensions followed by simultaneous crosslinking of PEO chains and reduction of Fe(III) precursor. -irradiation dose and concentrations of Fe, 2-propanol and PEO in the initial suspensions were varied and optimized.

Nanostructured Silicon as Potential Anode Material for Li-Ion Batteries.

Commercial micrometer silicon (Si) powder was investigated as a potential anode material for lithium ion (Li-ion) batteries. The characterization of this powder showed the mean particle size of approx.75.
