Opis:
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:
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:
Rare earth (RE) elements are important for the optical tuning of wide bandgap oxides (WBO) such as β-Ga2O3 or ZnO, because β-Ga2O3:RE or ZnO:RE show narrow emission lines in the visible, ultra-violet and infra-red region. Ion implantation is an attractive method to introduce dopant into the crystal lattice with an extraordinary control of the dopant ion composition and location, but it creates the lattice damage, which may render the dopant optically inactive. In this research work, we investigate the post-implantation crystal lattice damage of two matrices of wide-bandgap oxides, β-Ga2O3 and ZnO, implanted with rare-earth (RE) to a fluence of 5 x 10^14, 1 x 10^15 and 3 x 10^15 atoms/cm^2, and post-growth annealed in Ar and O2 atmosphere, respectively. The effect of implantation and annealing on both crystal lattices was investigated by channeling Rutherford backscattering spectrometry (RBS/C) technique. The level of crystal lattice damage caused by implantation with the same RE fluences in the case of β-Ga2O3 seems to be higher than in the case of ZnO. Low temperature photoluminescence was used to investigate the optical activation of RE in both matrices after performed annealing.

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.

In this study, the influence of polysorbate 80 on zinc oxide flotation was investigated with an amine collector. 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.

Opis:
In this study, physical and functional properties of the cement composites containing ZnO, ZnO/lignin and lignin admixtures were investigated using Response Surface Methodology (RSM). The I-optimal design based on RSM was used to assess the influence of ZnO-based doping agent, of either commercial or synthetic origin, on cement composite production in the function of average compressive strength and cost. Polynomial mathematical models were developed by RSM confronting results from the experimental design. The accuracy and precision of the utilized models established by I-optimal design were tested using Analysis of Variance (ANOVA). The first stage of formulation optimization revealed that the use of commercially available ZnO-based admixture no. 4 (ZnO-SA, supplied by Sigma Aldrich) allowed to achieve the desired results, passing all the requirements, i.e., the best microbial purity combined with reasonable cost, followed by satisfactory physical properties. In the second stage of formulation optimization, the influence of implementing the hybrid materials, i.e., ZnO-SA mixed in different proportions with lignin was evaluated. RSM revealed that doping admixture no. 3, i.e., ZnO-SA/lignin (5:1), is the best candidate, which comprised augmented functional and physical properties of the fabricated cement composite. This component exhibited the best microbial purity as well as the lowest total pore volume, followed by satisfactory physical properties. Verification of the model findings indicated considerable agreement between the predicted and experimental values. From the findings, it was confirmed that a reasonable cost-performance balance for cement composites can be achieved using ZnO-SA and ZnO-SA/lignin (5:1).

A n-type semiconductor ZnO has high transmittance features, excellent chemical stability and electrical properties. It is also commonly used in a range of fields, such as gas sensors, photocatalysts, optoelectronics, and solar photocell. Magnesium-doped zinc oxide (Mg-ZnO) nano powders were effectively produced using a basic chemical precipitation process at 45°C. Calcined Mg-ZnO nano powders have been characterized by FTIR, XrD, SEM-EDX and Pl studies. XRD measurements from Mg-ZnO revealed development of a crystalline structure with an average particle size of 85 nm and SEM analysis confirmed the spherical morphology. Electrochemical property of produced Mg-ZnO nanoparticles was analyzed and the specific capacitance value of 729 F g-1 at 0.5 A g-1 current density was recorded and retained a specific capacitance ~100 percent at 2 A g-1 current density.

The aim of this work was to study the activity of unmodifi ed and modifi ed ZnO in the peroxide crosslinking of hydrogenated acrylonitrile-butadiene elastomer (HNBR) and ethylene-propylene copolymer (EPM). In the fi rst step, zinc oxide was obtained by emulsion precipitation. Maleic acid was introduced onto the surface of ZnO Rusing an in situ method. The unmodified and modified zinc oxide was characterized using dispersive and morphological analysis, BET surface area analysis, and elemental, spectroscopic and thermal analysis. In the second stage of the research, the ZnO/MA systems were incorporated into the structure of elastomer compounds improving the kinetic and mechanical properties of vulcanizates. The proposed modification method had a favorable effect on the physicochemical properties of the zinc oxide and on the kinetic and mechanical properties of the vulcanizates. This study demonstrated that modification of zinc oxide by maleic acid is a promising technique.

Opis:
Zinc oxide (ZnO) has been applied for many years in the production of pigs to reduce the number of diarrhoea in weaned piglets. In June 2022, the European Union banned the use of zinc oxide (ZnO) in pig feed. According to scientific reports, the may reason was the accumulation of this microelement in the environment of pig production. It has been shown that frequent application of ZnO can lead to increased antibiotic resistance in pathogenic swine microflora. The main alternatives to ZnO are probiotics, prebiotics, organic acids, essential oils, and liquid feeding systems. Alternatives to ZnO can be successfully used in pig production to reduce the number of diarrhoea among piglets during the postweaning period. Additional reports indicated that bacteriophage supplementation has a positive effect on the health of pigs. The article provides an overview of current ZnO substitutes that can be used in pig farming.
