Summary: This research investigates the electrochemical properties of PEDOT films and finds that film thickness plays an important role in the ordered structure and charge storage capacity. A 30 nm thick PEDOT film exhibits the highest face-on structure and the lowest charge storage capacity. Mixed domain films show higher charge storage capacity, likely due to the easier access of electrolyte to the edge region of PEDOT, facilitating faster ion transport.

Summary: The influence of europium on the structure and luminescent properties of CaWO4 thin films was investigated, and the sputtering yields of different compounds were studied. The results showed that the compositions of the deposits matched those of the targets, and the lattice constants increased under certain conditions. The preferential growth along a specific crystal plane also increased due to the substitution of Ca2+ with Eu2+. Doping of Eu led to improved photoluminescence performance of the films.

Summary: The deposition angle has a significant influence on the porosity, crystallinity, surface roughness, as well as the optical and electrical properties of nickel thin films. Variations in refractive index, extinction coefficient, and resistivity were observed with different deposition angles, which can be correlated with changes in microstructure and porosity of the films.

Summary: In this study, the microstructure and its effects on the electrical and optoelectronic properties of BaSi2 films grown by close-spaced evaporation were investigated. It was found that using Si(100) substrates, increasing film thickness and growth temperature can decrease the density of epitaxial domain boundaries, improve carrier lifetime, and enhance the performance of BaSi2 films for photovoltaic applications.

Summary: In this study, UO2 thin films were synthesized by CVD using a U(VI) precursor, and it was found that the application of magnetic fields can alter the morphology and crystallographic orientation of grains, reduce grain size, promote polycrystalline growth, and decrease surface oxidation of U(IV) centers. The presence of a magnetic field as an extrinsic parameter in the CVD process has a positive effect on controlling the texture and chemical homogeneity of the grown films.

Summary: Atomic layer deposition of praseodymium oxide films allows for uniform doping of HfO2 films with non-uniform thicknesses. The absorption of oxygen in PrOx-rich material enhances ALD growth, leading to thickness gradients in thicker films. Pr-doping stabilizes the tetragonal form and improves photoluminescence efficiencies in HfO2 films.

Summary: The global pandemic has caused a massive amount of unrecyclable plastic waste, especially from single use face masks. This study proposes a method of melting and mixing face masks with coal dust to create powder, addressing the environmental challenges. The results show that the melt-blended mask/coal dust material exhibits high CO2 gasification reactivity, suggesting its potential use in recycling steelmaking by-product dusts or direct injection to blast furnaces.

Summary: Solvent-assisted ligand exchange in Zr-MOF UiO-67 led to the synthesis of mixed MOFs UiO-67-TpTp and UiO-67-TzTz with lower BET specific surface area but maintained thermal stability. These MOFs show potential as sensors for contaminants of emerging concern in water, with UiO-67-TzTz also exhibiting adsorption capabilities.

Summary: This paper presents the development of green bio-composite mortars by reusing spent coffee ground (SCG) in the Circular Economy approach. The addition of SCG in the mortar resulted in a more compact structure and various concrete applications. Despite a decrease in bulk density, the mechanical performance remained suitable for masonry applications. The reused bio-waste also led to a reduction in manufacturing cost and showed promising potential for energy-saving uses in buildings.

Summary: An AGS SBR reactor adapted to salinity was used for the treatment of synthetic saline wastewater containing EDCs. The results showed that E2 was completely biodegraded, while the removal efficiency of EE2 and BPA was lower. The activity of phosphate-accumulating organisms was affected by EDCs, but the activity of ammonium- and nitrite-oxidizing bacteria was not significantly affected. The microbial diversity increased after the addition of EDCs.
