In recent years, interest in sustainability and being environmentally friendly has increased. Wood is a durable and renewable building material, which is becoming more common in the constructions industry. In 2002, the government in Sweden adopted a national strategy to promote an increased use of wood in buildings. However, the usage of wood in co...
Prisotnost farmacevtskih učinkovin v okolju povzroča vse večjo zaskrbljenost, saj se proizvodnja in poraba le-teh iz leta v leto povečuje. Posledično se povečuje tudi njihovo izločanje v okolje. Običajne metode čiščenja na čistilnih napravah pri odstranjevanju zdravilnih učinkovin niso uspešne, zato so se raziskave osredotočile na sklopitev biološk...

Thin films of ZnO with different thicknesses (ranging from 8 to 40 nm) have been prepared by plasma-enhanced atomic layer deposition. Grazing incidence x-ray diffraction shows the nano-crystalline structure of the films with high degree of disorder. The films have also lattice oxygen and non-lattice oxygen where the film with 20 nm thickness has th...

Recent experimental study of electron transport in ZnO/ZnMgO and BeZnMgO/ZnO heterostructures containing two-dimensional electron gas (2DEG) channels of two polarities is reported where electrons are accelerated and become hot by a pulsed electric field. The measurements with electrical pulses ranging from 2 ns to 10 ns in duration ensure the contr...

In this research, the adsorption of methylene blue (MB) and methyl orange (MO) on ZnO and nickel-doped ZnO (Ni-ZnO) clusters was investigated through the density functional theory (DFT). The study included the interaction with ionized MB, neutral MB, ionized MO and neutral MO. In the case of Ni-doped ZnO, the two probabilities of nickel multiplicit...

This work modelled and analysed perovskite solar cells based on Cs2AgBiBr6 with various electron transport layers and hole transport layers. The device structure is fluorine-doped tin oxide (FTO)/ZnO/Cs2AgBiBr6/NiO/Au. Power conversion efficiency (PCE) is practically saturated after the perovskite thickness of 700 nm. PCE declines from 21.88% to 1....

A comprehensive study is envisioned to examine the influence of rare-earth (RE) metal doping on the zinc oxide (ZnO) matrix. A wet-chemical methodology is adopted to synthesize pristine and neodymium (Nd)-doped ZnO nanoparticles (NPs). Crystal structure analysis substantiates that RE doping does not form any secondary phases related to RE metal clu...
The original technique developed for the direct incorporation and efficient dispersion of silver metal NPs into ZnO precursor solution allowed us to elaborate nanocomposite thin films with a large effective surface area for interaction with the external environment as well as a large surface area for metal–semiconductor interaction suitable for sur...

In this study, we have investigated the role of natural dead sea sponge (DSS, Porifera) as a three-dimensional (3D) porous host substrate for the immobilization of nanostructured ZnO material towards the development of ZnO based floating photocatalysts for efficient removal of methylene blue (MB) dye under the illumination of sunlight. After photod...

Zinc oxide is a popular semiconductor used in catalysts due to its wide bandgap and high exciton binding energy. However, the photocatalytic performance of ZnO was compromised by its insufficient electron-hole separation efficiency and electron transfer rate. Herein, ZnO-reduced graphene oxide (rGO) composite solid catalyst was synthesized by one-s...
