AB  - The BiVO4 sample was successfully synthesized from a mixture of ammonium vanadate, bismuth(III) nitrate, and nitric acid exposed to ultrasound irradiation. Structure, microstructure and optical properties of the obtained BiVO4 nanopowder were investigated. X-ray diffraction (XRD) analysis confirmed single phase monoclinic lattice system with average crystallite size of 50 nm in diameter. Scanning electron microscopy (SEM) micrographs revealed the tendency of crystallites to agglomerate forming larger irregular sub-micron spheres. Brunauer-Emmett-Teller (BET) method was used to estimate the specific surface area of the sample and determine pore shape and size. UV–vis spectroscopy measurements have revealed favorably high absorbance of the visible light with the calculated band-gap value of 2.48 eV. Calculated values of valence and conducting band energies are +2.77 eV and +0.29 eV respectively, suggested that BiVO4 can be used for photocatalytic degradation under sunlight irradiation as evident from the UV–vis spectrum.

AB  - Mesoporous TiO2 films with spherical architectures and promising performance in dye-sensitized solar cells (DSSCs) were prepared. The morphology of the films was investigated by scanning electron microscopy. Transmission electron microscopy analysis of the spheres disclosed the elongated shape of sub-20nm primary particles, while BET analysis revealed their high surface area of 135 m(2)/g. Anatase presence was observed in the films based on X-ray diffractometry, selected-area electron diffraction analysis and Raman spectroscopy analyses. Increased light scattering of the spheres in visible region was observed by UV-VIS-NIR spectroscopy. Photovoltaic performance of the operating N719-sensitized cells was tested using electrochemical impedance spectroscopy and current density-voltage (J-V) curves under simulated AMI. 5 spectrum. The 0.25 cm(2) cells exhibited photo-to-electric power efficiency of 4.9%, which is among noteworthy values for DSSCs with similar photoanodic structures.

AB  - For long-term protection of stored products there is a growing demand to replace chemical insecticides due to their effects on human health and environmental safety. Particulate materials, such as inert dusts and various submicron and nanomaterials have been extensively tested as viable alternatives. This is the first study on the insecticidal impact of alumina powder (alpha-Al2O3) on the bruchid pest, Acanthoscelides obtectus (Say) (Coleoptera: Chrysomelidae: Bruchinae). By altering the fuel to oxidant molar ratio (F/O: 0.5, 0.8, 1.2) in an autocombustion reaction we synthesized alumina powders with specific surface area and particle size varying from the nano- to micron scale. It was found that particle morphology influenced survival and progeny number of A. obtectus. The order of powders from low to high efficacy in reducing beetle performance (F/O-0.8  lt  F/O-0.5  lt  F/O-1.2) correlated well with increase in surface area, pore volume and diameter, and decrease in particle size. Survival was also affected by time of exposure, the applied dose and sex. The estimated median lethal concentration of the most efficient powder F/O-1.2 was significantly lower in males (LC50 = 330.4 ppm) than in females (LC50 = 409.6 ppm). Our results suggest that alumina powder can be considered for seed protection against A. obtectus, particularly during long-term storage, as it is cost effective, exerts limited toxicity to humans and demands no repetitive use like conventional pesticides.

AB  - In this paper, we propose a novel method for preparation of high surface area titania nanoparticles, and investigate their photovoltaic performance in dye sensitized solar cells (DSSCs). The precursor compound titanium(IV)-isopropoxide is hydrolyzed in the presence of nonionic surfactant (Triton X100) and ethylenediaminetetraacetic acid sodium salt (EDTA-Na-2) and thermally transformed into gel. The gel is autoclaved, resulting in submicronic micelles which are further processed into mesoporous films. The films are deposited from paste, composed of ultrasonically broken micelles and the organic ingredients. The crack-free film structures, composed of sub-25 nm pure anatase particles are observed using the appropriate instrumental techniques: scanning electron microscopy (SEM), field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffractometry (XRD), UV-VIS-NIR spectroscopy. The large surface area of 158 m(2) g (1) and mesoporosity are confirmed using the data obtained from the nitrogen adsorption-desorption isotherm. The photovoltaic performance of the operating N719-sensitized solar devices are tested using electrochemical impedance spectroscopy (EIS), open-circuit voltage decay (OCVD) and by recording current density-voltage (J-V) curves. The cell exhibits promising photocurrent density up to 11.7 mA cm (2), and the photo-to-electric power efficiency of 5.22%, for cell area of 0.24 cm(2), under 100 mW cm (2) halogen light source.
