AB  - In this paper we propose a possible use of butterfly scales as templates for ordered 2D or 3D nanophotonic materials, with complexity not easily reproducible by conventional micro/nanofabrication methods. Functionalization through laminar nanocompositing is utilized to impart novel properties to the biological scaffold. An extremely wide variability of butterfly scale forms, shapes, sizes and fine structures is observed in nature, many of them already possessing peculiar optical properties. Their nanophotonic functionalization ensures a large choice of forms and functions, including enhanced light localization, light and plasmon waveguiding and general metamaterial behavior, to mention a few. We show that one is able to achieve a combination of plasmonics and bionics, resulting in functionalities seldom if ever met in nature. As an illustration we have analyzed the photonic properties of the nanostructured scales on the wings of Purple Emperor butterflies Apatura ilia, Apatura iris and Sasakia charonda. Their intricate nanometer-sized structures produce remarkable ultraviolet-blue iridescence, spectrally and directionally narrow. We present our analysis of their plasmonic/nanophotonic functionalization including preliminary calculations and initial experimental results. As a simple example, we used radiofrequent sputtering to produce nanoaperture-based plasmonic structures at a fraction of the cost and necessary engineering efforts compared to the conventional top-down methods. We conclude that the described pathway to biomimetic plasmonics offers potentials for significant expansion of the nanophotonic and nanoplasmonic material toolbox.

AB  - In this study, the feasibility of preparing porous TiO2 films on a stainless steel substrate from a hydrothermally prepared colloidal TiO2 solution by the spray pyrolysis technique is presented. The prepared samples were annealed at different temperatures and characterized by the XPS, XRD and SEM techniques, porosimetry and specific surface area measurements. The photocatalytic activities of the resulting films were evaluated by measuring the degradation of an azo pyridone dye, used as model pollutant, under simulated sunlight conditions. The relationships between the structural and morphological characteristics of the TiO2 films and their photoactivity were observed. It was found that the photoactivity was markedly dependent on the annealing temperature. On increasing the calcination temperature from 500 degrees C to 700 degrees C, the crystallite size and the rutile content increased, whereas the specific surface area and the rate of photodegradation decreased. Calcination at 700 degrees C resulted in a completely loss of photoactivity, due to the partial transformation of anatase to rutile phase, the increased crystallite size and decreased specific surface area. Specific activity (per unit of mass and per unit of surface area) was lowered within thicker films, pointing out significance of transport phenomena through porous films (the transport of dye and the transmittance of light as immaterial reagent). Based on the obtained results, the spray pyrolysis method appears to be a good choice for the preparation of photocatalytically active TiO2 films for the removal of dye pollutants.

AB  - Size-segregated urban aerosol of Belgrade center (44049'14''N, 20027'44''E) was studied during the summer-autumn 2008. The representative location in traffic area Studentski trg was chosen for investigating physical and chemical characteristics of collected particles. Particle size distribution in the size range Dp = 0.49 m, 0.49 = Dp = 0.95 m, 0.95 = Dp = 1.5 m, 1.5 = Dp = 3.0 m, 3.0 = Dp = 7.2 m and Dp = 7.2 m were measured. Aerosol samples were submitted to gravimetric SEM analysis. The shape, size and chemical composition of the fine and coarse particles were analyzed. The imaging was carried out by SEM (Nova NanoSEM 230, FEI, USA). The same SEM was also used for the EDX measurements performed. The particles collected on fiber filters for SEM imaging were further on coated with 4 nm Pt layer to improve conductivity of the samples. The morphological and chemical composition suggested that the most abundant particles were carbonaceous soot but also microbes and natural and anthropogenic inorganic mineral materials. The chemical characterization was performed on a semi-quantitative level. The contents of the carbon were up to 70% or higher. In the samples were dominating next others elements: O, Mo, Si, Fe, Ca, Al, K, Mg.
