Opis:
The aim of the study was to determine the effect of spinosad on soil biochemical and microbiological properties. The experiment was carried out on sandy loam with Corg content 10.91 g·kg-l. Spinosad, as Spintor 240 SC was added into soil in dosages: a recommended field dosage, and fivefold, tenfold, and twenty-fivefold higher dosages. The amount of spinosad introduced into soil was between 12.55 and 313.75 g·kg-l. Moreover, soil samples without spinosad supplement were prepared as a reference. Respective Spintor 240 SC doses were converted into 1 kg soil, taking into account 10 cm depth. After application of insecticide water emulsions, soil moisture was brought to 60% maximum holding water capacity. The soil was thoroughly mixed and stored in tightly-closed polyethylene bags at 20 °C for a period 4 weeks. During the ex-periment dissipation of spinosad, soil enzymes (dehydrogenase, alkaline phosphatase, acid phosphatase, urease) and number of bacteria, fungi, actinomycetes were assayed. Obtained results showed, that dissipation of spinosad in soil was relatively fast – the DT50 of this insecticide was ranged between 1.11 and 2.21 days. Spinosad residues had different effects on soil microbiological and biochemical properties. However, over time the impact of this insecticide definitely decreased. This indicated that the use of spinosad in organic farming, particularly in the field dosage, does not pose a long-term threat to the soil environment.

Opis:
Spectroscopic and photophysical properties of the poly(azomethine)s with triphenylamine moieties were investigated by UV-vis, X-ray diffraction and atomic force microscopy methods. Current-voltage measurements were performed on ITO/polymer/$Alq_3$/Al, ITO/PEDOT/polymer:MWCNT/Al and ITO/polymer:MWCNT/Al devices. Multiwall carbon nanotubes were blended with polymer in the ratio 1:1. The lowest optical band gap value at 2.33 eV was detected. Moreover, an absorption coefficient α was calculated from transmission and reflectivity measurements. In this paper, we presented photophysical and structural properties of the poly(azomethine)s in solid state of great interest for the emerging field of molecular electronics and for their uses as active layers in (opto)electronic devices such as solar cells.

Opis:
A development of high-performance materials for electronics, optics, ceramics fabrication is restrained by traditional modes of their production. Basic technologies for materials include high-temperature physical and chemical processes and require special conditions to attain desired properties of final products. Advanced preparation methods for materials with new features are feasible on the basis of colloid-chemical processes and nanochemistry. In this respect the sol-to-gel transformation followed by solidification and chemical modification are of great interest to attain a variety of different functional properties of materials.

Opis:
The sol-gel derived silica spheres with surfaces modified by silver nanoparticles were used to enhance the photodynamic effect. The silica nanoparticles were prepared by modified Stöber synthesis. The diameter of obtained silica spheres was ca. 100 nm. These silica spheres we used as a carrier for noble nanoparticles. It was shown that Ag-Au nanoparticles have an antibacterial activity against Escherichia coli. This effect depends on the nanoparticles concentration and it is stronger for higher concentrations. Laser irradiation enhances this effect, and starting from certain concentration it is possible to kill Escherichia coli, totally, when using laser light.

Opis:
The sol-gel derived silica spheres with surfaces modified by silver nanoparticles were used to enhance the emission efficiency of PDTphotosensitizer Photolon. Two various materials with different Ag concentrations were prepared by exploiting the Tollen's method. The silica nanoparticles were prepared by modified Stöber synthesis. The diameter of obtained silica spheres was ca. 100nm. These silica spheres we used as a carrier for noble nanoparticles, since they can be easily doped by various substances that can change their physical and chemical properties. The colloidal water solutions of Ag-doped SiO2 particles have been prepared. It was demonstrated that the fluorescence intensity of Photolon is influenced by silver nanoparticles concentration, however it is not proportional to the silver concentration. The fluorescence intensity of Photolon with silver doped silica nanoparticles is much higher then fluorescence intensity of Photolon in water solution. This result is very promising and may be used to enhance the photodynamic effect.

We report explicit vibronic intensity calculations for the |$\text{}^{4}$S$\text{}_{3}\text{}_{/}\text{}_{2}$ Γ$\text{}_{8}$> → |$\text{}^{4}$I$\text{}_{15}\text{}_{/}\text{}_{2}$ Γ>excitations in the Cs$\text{}_{2}$NaErCl$\text{}_{6}$ elpasolite-type systems, based upon new and updated experimental data, obtained from optical absorption measurements made at 10 K, in the energy range from 6,000 up to 26,000 cm$\text{}^{-1}$. Our calculation model is a generalization of the vibronic crystal field-ligand polarization method and the calculation is performed using a minimum set of adjustable parameters - all and each of them have a clear physical meaning. Our strategy was chosen so as to make a significant distinction with previous calculations, performed by other authors, who have worked out a model originated from a supra-parameterized scheme, within the framework of the superposition model of Newman. Throughout the course of the current work, it is shown that our model is suitable to handle this kind of calculations and also that the numerical results obtained are in fairly good agreement with experiment.

Opis:
In this work we report both experimental and theoretical studies regarding the Cs$\text{}_{2}$NaTmCl$\text{}_{6}$ elpasolite-type system, for which we have an updated database from linear and nonlinear optics. Both the absorption and the emission spectra for this system are rather complicated and a generalized vibronic crystal field-closure-ligand polarization calculation model has been employed to rationalize the observed spectral intensities. The calculation has been carried out by neglecting the interaction among the internal and the external vibrations and theoretical calculations have been performed with reference to both the emissions $\text{}^{3}$H$\text{}_{4}$(Γ$\text{}_{i}$)>$\text{}^{3}$F$\text{}_{4}$(Γ$\text{}_{j}$) and the absorptions $\text{}^{3}$H$\text{}_{6}$(A$\text{}_{1}$)> $\text{}^{3}$F$\text{}_{4}$(Γ$\text{}_{i}$), $\text{}^{1}$G$\text{}_{4}$(Γ$\text{}_{i}$), $\text{}^{3}$H$\text{}_{5}$(Γ$\text{}_{l}$) withΓ$\text{}_{k}$ (k=i,j)=A$\text{}_{1}$,E,T$\text{}_{1}$,T$\text{}_{2}$ andΓ$\text{}_{l}$=E, $\text{}^{a}$T$\text{}_{1}$, $\text{}^{b}$T$\text{}_{1}$,T$\text{}_{2}$. The advantages and disadvantages of our model calculation are discussed in the text, and despite the simplicity of the model it is shown that it has got some utility and flexibility to gain understanding in these complex phenomena.

Vibronic spectra of Gd$\text{}^{3+}$ in Cs$\text{}_{2}$NaGdCl$\text{}_{6}$ were measured under one- and two-photon excitations. Following the vibrational analysis of the Cs$\text{}_{2}$NaGdCl$\text{}_{6}$ crystal an assignment of vibronic transitions was proposed. It was found that the vibronic transitions in one- and two-photon spectra are combined with the odd parity modes.

Theeffect of freon heat treatment on optical properties of Er-doped silica glasses obtained by the sol-gel method was investigated. It was found that fluorine ions in the process of hydrolysis replace hydroxyl ions in the host and form the complexes with Er$\text{}^{3+}$ ions. It leads to a significant improvement of optical properties of Er doped silica glass.
