Summary: This study utilized the abundant mineral chalcopyrite as an efficient trap for Hg-0 sequestration, showing excellent removal performance in a wide temperature range and minimal interference from typical flue gas components. The adsorption capacity and rate of CuFeS2 were significantly higher than commercial activated carbons, attributed to the oxidizing and immobilizing abilities of disulfide ligands, and the sorbent could be regenerated through thermal decomposition, saving operation costs. CuFeS2 is identified as a potential, cost-effective trap for efficient remediation of Hg-0 from coal combustion flue gas.

Summary: Phase transformations over a nanocrystalline iron catalyst were investigated during the nitriding process at 350 degrees C and atmospheric pressure. The study revealed four stages of nitriding and identified the corresponding chemical reactions. The magnetic permeability was found to strongly depend on the nitriding degree, with significant differences observed between different phases. However, the magnetic permeability of the smallest nanocrystallites did not change with the nitriding degree. Additionally, it was observed that the composition of iron nitrides and the concentrations of nitrogen in iron nitrides were influenced by the direction of the reaction (nitriding or reduction).

Summary: A porous TiO2 layer was prepared by plasma electrolytic oxidation (PEO), followed by deposition of Pd on the TiO2 surface layer using the adsorption method. The Pd/TiO2/Ti catalyst exhibited high activity for the oxidation of CO to CO2 in air with 5% CO. The optimal Pd concentration on the catalyst surface was found to be approximately 0.14% wt., and increasing the PdCl2 concentration did not further improve the catalyst activity.

Summary: This study evaluated the service life of dental restoration materials in aggressive environments. The results showed that neat resins exhibited poor durability, while materials with lower bis-GMA content or substituted by bis-EMA showed better resistance to degradation. Choosing monomer mixtures with lower sorption values may improve hydrolytic stability. The composites experienced a significant decrease in hardness, indicating a more superficial effect of the aging protocols.

Summary: The activity of Pd/TiO2/Ti catalyst in CO oxidation was improved by adding Zn. Plasma electrolytic oxidation (PEO) was used to produce a porous layer of TiO2 on Ti wire. Pd and Zn were introduced through adsorption, and the activity was examined by CO oxidation. Model catalysts were prepared to investigate the reaction between Pd and Zn. Characterization techniques such as SEM-EDS, TOF-SIMS, ICP-MS, FTIR, and XRD were used to analyze the structures and compositions of the samples. Zn modification of the Pd/TiO2/Ti catalyst decreased the temperature of CO oxidation and improved the adsorption of oxygen.

Summary: This study presents a mechanistic investigation of methane oxy-steam reforming and LNG (OSR-LNG) processes using Fourier transform infrared (FTIR) spectroscopy for the first time. FTIR measurements were conducted in the temperature range of 200-600 degrees Celsius to propose the reaction mechanisms of oxy-steam reforming of CH4 or LNG. It was discovered that the dissociation of methane into carbon-containing molecules and/or onto the catalyst surface is a crucial step in determining the reaction rate. These findings can be applied to the design of catalytic systems for natural gas reforming.

Summary: Investigation on the course of the Boudouard reaction and methane cracking was conducted using nickel catalysts based on calcium, aluminum, and magnesium oxides. The study revealed that the optimal temperatures for these reactions were 450 and 700 degrees C, respectively, resulting in the successful formation of graphite-like carbon species. The activity of the catalytic systems was found to be directly related to the number of weakly interacted nickel particles with the catalyst support.

Summary: In this study, multi-walled carbon nanotubes (MWCNTs) were prepared by chemical vapour deposition (CVD) using acetylene as a carbon source over an iron catalyst. The feasibility of MWCNTs supported monometallic and bimetallic catalysts for hydrogen production during steam reforming of methanol (SRM) and methanol decomposition (DM) was investigated. SEM and XRD methods were used to evaluate the structural characteristics of MWCNTs. TPR and XRD methods were used to analyze the physicochemical properties of the catalysts. The promotion effect of palladium on methanol conversion rate and H2 productivity in the case of the copper catalysts was demonstrated, which was attributed to the formation of Pd-Cu alloy compound.

Summary: The effect of a new etching technique (Zircos-E) on Ceramill Zi (Amann Girrbach) zirconia was investigated. Surface preparation for bonding is difficult due to the polycrystalline structure of zirconia. Etching zirconia ceramics resulted in changes in surface structure and increased bond strength with resin cement. The use of primers positively affected the adhesion between resin cement and zirconia. The Zircos-E system and primers improved the strength of the zirconium-resin cement connection.

Summary: The Flow Diverter is a treatment method for fusiform aneurysms, commonly used for cerebral vascular anomalies but not for aortic aneurysms. Numerical simulation in a patient-specific model of abdominal aortic aneurysms allowed investigation and visualization of blood hemodynamics before and after stent implantation. The Flow Diverter stent significantly changed the flow pattern in the aneurysm region but did not affect blood flow to the renal arteries.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
