Tea is a traditional beverage. There are different types of tea, such as black, white, green, oolong, and herbal teas. In recent years, lotus tea has been increased interest. This study aimed to assess the physicochemical properties, bioactive compounds o... see more

Ag–TiO2 thin film was fabricated by DC magnetron sputtering and photoreduction methods. Characteristics of the film such as surface area, crystal structure, and chemical composition were investigated by using scanning electron microscope (SEM), X–ray diff... see more

Organometal halide perovskite materials have shown high potential as light absorbers for photovoltaic applications. In this work, perovskite planar solar cells were fabricated on corning substrates with the structure as follows: the first layer made of ta... see more

This study focuses on the influence of gold nanoparticle sizes on optical and electrical properties of Au@TiO2 nanocomposite films. Here, the gold nanoparticles (AuNPs) of different sizes of 5 nm, 10 nm, 20 nm, 40 nm and 60 nm were dispersed onto nanoporo... see more

Aluminum doped zinc oxide was prepared by magnetron sputtering methods at room temperature using a ZnO ceramic target doped 2%wt by Al2O3. The optical transmittance of the films is higher than 80% in the visible range. A direct bandgap type was reached by... see more

The ZnS:Cu nanopowders were synthesized by the wet chemical method with Cu concentrations of 0.1, 0.15, 0.2, 0.3 and 0.4{\%}. The microstructure of samples was investigated by the X-ray diffraction (XRD) measurement. The results show that the prepared ... see more

It is known that overexpression of isozymes of glutathione S-transferase family is one of the causes for the resistance of cancer cells to the action of drugs. Therefore, inhibitors of these enzymes can be considered as potential drugs.Aim. To assess in s... see more

This paper elucidates the articulated proposals for the initial stages of adult third language (L3) syntactic transfer, addressing their application for L3 and the subsequent fourth language (L4) acquisition. The study was set to demonstrate empirical evi... see more

The transformation of the education system under the neoliberal principles of privatisation andmarket counted in Chile firstly on the military power of Pinochet’s dictatorship (1973-1990) andthen on the consent of the coalition of centre-left wing parties... see more
