Opis:
Mimo znaczącej redukcji kosztów paneli fotowoltaicznych (PV), cena energii wytwarzanej przez baterie słoneczne ciągle jest za wysoka. Możliwe są dwie strategie rozwiązania tej sytuacji – (a) podniesienie wydajności konwersji światła w komórkach fotowoltaicznych lub/i (b) obniżenie kosztów paneli PV poprzez zastosowanie tańszych materiałów lub technologii. W referacie omówione są prace mające na celu: (a) zastąpienie zbyt drogiego ITO warstwami ZnO o przewodnictwie metalicznym, (b) uproszczenie konstrukcji komórek PV oraz (c) znalezienie alternatywnych materiałów.
Despite of a large reductions of costs energy produced by solar panels is still too expensive. There are two approaches to change this situation: by (a) increase of device output and/or (b) reduction of device costs by use of cheaper alternative materials. In this article we discuss the latter approach – (a) replacement of ITO by ZnO with metallic conductivity, (b) change of device architecture, and (c) use of alternative materials.

Opis:
Recently the one-dimensional ZnO nanostructures have attracted much attention in gas sensor applications owing to their increased role of the surface. The authors have obtained ZnO rods of sub-micron size using the solution growth method with the growth temperature below 100.C. Investigations indicate that the rods have a well-defined hexagonal morphology and a wurtzite structure. The best uniformity and alignment of the sub-micron crystals was however obtained when electrodeposition from aqueous solution was developed. Sizes of these rods depend on the growth parameters. Moreover electrodeposition leads to a faster growth rate of ZnO sub-micron rods (2 hrs) as compared to the growth from solution (8 hrs). After electrodeposition the rods can be easily reoriented in external electric fields by using substrates with electrodes of appropriate geometry and configuration (dielectrophoretic effect). This enables the preparation of samples which can be used in gas sensor technology.

Opis:
This study aimed to produce gellan gum-based hydrogels with the addition of zinc oxide as a potential dressing material. Hydrogels with ZnO concentrations of 0.01%, 0.02% and 0.04% were prepared, micrometric and nanometric ZnO particles were used, and a CaCl2 crosslinker was added to one part of the samples. All samples (14 types) produced by the freeze drying method were characterized with high swelling properties (>2000%), what is important to ensure the absorption of exudates from wounds. Samples with ZnO particles cross-linked with CaCl2 lost less mass after incubation in aqueous media and were characterized by better dimensional stability than those without crosslinking. The pH of the extracts of the samples containing ZnO particles was more neutral (pH 7.0-7.6) than that of the control gellan gum samples (pH of 5.5-6.1). The zinc release from cross-linked samples was twice as high for those containing nanometric particles than for micrometric particles (1.94 ± 0.04 mg/l and 0.93 ± 0.02, respectively). Relatively large amounts of released zinc species in the case of samples containing ZnO nanoparticles are promising in the context of the antibacterial properties and treatment of infected wounds. A lower amount of zinc released from samples with ZnO microparticles could be sufficient to prevent the development of the infection. Furthermore, both materials show satisfactory cytocompatibility with L929 fibroblasts, as shown by Alamar blue and live/dead viability tests, making them prospective candidates for wound healing

Opis:
We performed cathodoluminescence (CL) investigations of zinc oxide monolayers obtained by atomic layer deposition. Layers of different thickness were deposited on commercial GaN/sapphire templates. Scanning electron microscopy (SEM) system equipped with CL allows direct comparison of SEM images and CL maps, taken from exactly the same areas of samples. In addition to SEM and CL images, CL profiling was performed by collecting the CL spectra at different accelerating voltages. The CL profiling allows to distinguish the emissions from a surface and volume of samples. An inter-link between samples microstructure and emission properties is investigated. Shifts of emission bands, associated by us with the localization effects, are observed. CL investigations are supported by photoluminescence (PL) measurements, which are characterized by a higher spectral resolution. PL investigations allow determination of the origin of emission bands.

The leaching of low grade zinc oxide mining tailings by organic acid as a leaching agent was investigated. Zinc was extracted successfully from sample by citric acid leaching. The effects of solid-to- liquid ratio, acid concentration, reaction time, temperature and ore particle size on the leaching efficiency were studied. The results obtained showed that particle sizes and reaction time had not any significant effect on the leaching recovery of zinc from smithsonite in the sizes range of 40-350 μm. Under conditions: temperature of 80ºC, reaction time of 60 min, citric acid concentration of 0.5 mol/L, and solid to liquid ratio of 1:10, 82% of zinc could be recovered.

The results indicated that the pretreatment of amines with polysorbate 80 enhanced the Zn grade and recovery obtained using zinc oxide flotation. Desliming prior to flotation is not suggested based on the results of this study. The appropriate temperature for flotation was as low as 8 °C, and this flotation method also could be applied to different types of zinc oxide ores. Under optimum flotation conditions, a concentrate with a Zn grade of 48.34% and a Zn recovery of 95.97% was obtained.

Opis:
There is an increasing trend in the modern construction industry to use nanomaterials, which allow to improve the performance of construction materials on the one hand, and to shape new properties on the other. This study presents the results of physicomechanical and antibacterial tests for cement composites modified with zinc nanooxide. The main aim of this study was to compare the structural and morphological properties of three selected commercial zinc nanooxides and to determine the influence of the above mentioned nanooxides on the physicomechanical properties of cement composites and the ability to inhibit the activity of gram-positive and gram-negative bacteria as well as fungi. It was shown that commercial nanooxides can significantly differ in terms of physicochemical properties, which depend on their production method. Two of them were characterized by high specific surface areas, which in turn translated into rheological properties of cement mortars. Nanooxides with higher specific surface areas tend to reduce the plasticity of the mortars. According to the literature data, all nanooxides caused a delay in cement binder setting by more than 100%. This resulted in a reduction of the early one-day flexural and compressive strength of the composite. In the later curing period, especially after 7 days of hardening, a significant acceleration of the hydration process was observed in composites with the addition of all nanooxides, which was confirmed by significant increases in mechanical parameters. Nevertheless, the tested nanooxides showed different sensitivity towards microorganisms, which was influenced by both the type of nanooxide and bacteria.

Opis:
Heavy metal is a type of metal that has a high density and high toxicity when consumed by living things, especially humans. To prevent the impact of environmental pollution, optimal handling of wastewater containing heavy metals is required, including the wastewater from laboratories. This research aimed to study the effect of pH, catalyst dose, and irradiation time on the reduction of Copper (Cu), Iron (Fe), and Lead (Pb) heavy metals and their application to laboratory wastewater treatment. Among the Advanced Oxidation Processes (AOPs) methods, photocatalysis was chosen to reduce the level of Cu, Fe, and Pb heavy metals where zinc oxide (ZnO) is used as a photocatalyst and the sunlight as a light source. To determine the effect of pH, catalyst dose, and time on the reduction of heavy metal levels, firstly, this research used the synthetic wastewater containing Cu, Fe, or Pb heavy metals. On the basis of the experimental results, it is concluded that the pH value, catalyst dose, and time affect the photocatalytic process, decreasing the levels of Cu, Fe, and Pb metals. The optimum pH value obtained for Cu was at pH 7–8, for Fe it was at pH 6, and for Pb it was at pH 8; in turn, the metal removal percentages were 99.46, 99.91, and 99.70%, respectively. In the photocatalysis of synthetic wastewater, high removal percentage of more than 99% was achieved by using 0.1 g/L catalyst. The optimum decrease of metals occurred in the first 15 minutes of solar irradiation where the removal percentage was close to 100%. In this study, the application of ZnO photocatalyst under solar irradiation can reduce the heavy metals content in the laboratory wastewater by almost 100%, which meets the environmental quality standard for Cu, Fe, and Pb.

Thin films of ZnO0.7NiO0.3 have deposited on glass substrates at room temperature by using thermal evaporation technique under vacuum 10-5 mbar. The optical properties and dispersion parameters of the films have been studied. Changes in direct optical energy band gap of films were confirmed before and after annealing. The optical energy gap Eg decreased from 3.11 to 2.86 eV with increasing of annealing temperature to 200 ºC. Some of the optical absorption parameters, such as optical dispersion energies Eo and Ed, Urbach tails EU , dielectric constant ε, the average values of oscillator strength So, and wavelength of single oscillator λo have been reported. An increase in the annealing temperature causes an increase in the average oscillator strength from 62.02 to 87.71 eV.

Opis:
In this study, firstly, the effects of ammonia concentration, leaching time and solid/liquid ratio on the leaching behaviour of zinc from a smithsonite (ZnCO3) ore sample in aqueous ammonia solutions were investigated at room temperature by chemical, X-ray diffraction (XRD) and Fourier-transform infrared (FT-IR) spectroscopy analyses. It was found that leaching ratio of zinc steeply increased from 30.1 to 76.2% with increasing ammonia concentration from 1.0 to 4.0 M and maximum zinc leaching ratio of 79.7% was reached after leaching in 13.3 M NH3 solution. The XRD pattern of the residue obtained after leaching in 4.0 M NH3 solution for 90 min at solid/liquid ratio of 0.15 g/mL, the optimum condition, showed that smithsonite phase in the ore sample almost completely dissolved whereas the gangue minerals goethite and calcite remained unaffected, confirming the selectivity of ammonia solution for zinc dissolution. Together with zinc, leaching ratios of cadmium were also determined. In second part of the study, precipitation tests (by complete drying at different temperatures) were conducted on dissolved zinc, carbonate and ammonia containing pregnant solutions obtained after selected leaching experiments. By complete drying of the pregnant solutions at low temperatures, i.e. 50°C, relatively pure solid zinc ammine carbonate (Zn(NH3)CO3) precipitates and at higher temperatures, i.e. 150°C, quite pure solid zinc carbonate hydroxide (Zn5(CO3)2(OH)6) precipitates could be prepared. High-temperature heating of Zn(NH3)CO3 and Zn5(CO3)2(OH)6 precipitates at 450°C yielded single-phase zinc oxide (ZnO). The chemical compositions, FT-IR spectra and scanning electron microscope (SEM) photographs of some of the precipitates were also presented.

Opis:
Zinc is a microelement essential for the body. It has a great impact on the proper development and renewal of tissues, reproductive system, skin condition, or immune processes. Zincis involved practically in all aspects of the immune system and the production and activation of white blood cells. This work aimed to determine the effect of zinc oxide nanoparticles (ZnONP) on the expression of pro-inflammatory proteins in murine macrophages RAW 264.7, activated with lipopolysaccharide (LPS). Using the immunodetection technique the expression of cyclooxygenase 2 (COX-2), prostaglandin E2 synthase (cPGES), prostaglandin F2α receptor (FP receptor) and nuclear factor Nrf2 was determined. Statistically the highest expression of COX-2, cPGES, and FP receptor was observed in LPS-activated macrophages. RAW 264.7 cells supplementation with ZnONP 100 nmol and 500 nmol and LPS activation resulted in repression of COX-2 and cPGES, and an increased expression of Nrf2 protein when compared to control. The results suggest an anti-inflammatory effect and activation of the antioxidant system by ZnONP in RAW 264.7 macrophages. It seems appropriate to conduct further research on the molecular mechanism of action of ZnONP in eukaryotic cells.

Zinc oxide nanoparticles (ZnO NPs) were synthesized by the green synthesis methods using aqueous extracts of Couroupita guianensis Aubl. This is an eco-friendly, time conservative and cost effective way of nanoparticle production. The aqueous extracts of leaves, stem, flower petals and bark were used to synthesize the nanoparticles. Zinc Nitrate hexahydrate (Zn (NO3)2•6H2O) was used as a precursor material. The prepared Zinc oxide nanoparticles were characterized using UV-Vis spectrophotometric analysis. The wavelength specific UV-Vis absorption peaks for Zinc oxide nanoparticles were recorded between 290 nm to 302 nm which confirmed the presence of Zinc oxide in nano scale. The reaction mixture with aqueous extract of leaf showed maximum absorbance spectral peak at 302 nm, stem at 294 nm, flower petals at 292 nm and bark at 288 nm. This is the first report to explore the use of Couroupita guianensis for the biogenic production of Zinc oxide nanoparticles to meet the demand of the pharmaceutical, medicinal and environmental industries.
