Summary: C-(A)-S-H phases with different C/S molar ratios were synthesized using the alkali-activation method and heavy metal ions were added. The effects of heavy metal ions on the structure of C-(A)-S-H were investigated using various analytical techniques. It was found that heavy metals could be immobilized through precipitation of insoluble compounds or by replacing Ca2+ ions in the aluminosilicate structure. Another possibility was the incorporation of heavy metal ions at the tetrahedral sites of silicon and/or aluminum.

Summary: A critical factor in achieving tunability in DESs is the variation of HBAs and HBDs. Choline fluoride-based DESs, such as EthalineF, were synthesized and characterized for the first time. Various spectroscopic techniques were used to study EthalineF, and measurements of polarity, density, viscosity, and conductivity were collected. The results showed that EthalineF has a larger solvodynamic radius compared to Ethaline, explaining the lower conductivity despite higher fluidity and solvation dynamics.

Summary: The solvothermal reactions of lanthanide salts with 1,2-phenylenediacetic acid in DMF solvent lead to the formation of metal complexes with structural similarities in two groups. Different characteristics are observed in lighter and heavier lanthanide complexes, such as the presence and coordination mode of DMF molecules, and the deprotonation of carboxylate groups. Thermal decomposition of isostructural complexes occurs similarly, with the formation of gaseous products. Luminescence properties in the visible and near-infrared regions are exhibited by the complexes of Eu, Tb, and Er.

Summary: This study synthesized complexes of chlorogenic acid (5-CQA) with copper(II) and iron(III) and analyzed their properties using various methods. The results showed the possible coordination of the complexes through the carboxylate group and the hydroxyl group from the catechol moiety. The complexes exhibited lower antioxidant properties in aqueous solution compared to 5-CQA alone, but showed higher antioxidant activity in the lipid peroxidation inhibition assay. Cu(II) 5-CQA exhibited the highest pro-oxidant activity among the studied compounds. The complexes were not toxic to HaCaT cells within the tested concentration range.

Summary: In this study, the toxicity and oxidative stress generation of the antidepressant fluoxetine (FLU), its metabolite nor-fluoxetine (Nor-FLU), the antibiotic nalidixic acid (NA), caffeic acid (CA), and their mixtures were investigated in three different environments: microbial medium (MM), raw wastewaters (RW), and treated wastewaters (TW). The results showed that FLU, Nor-FLU, NA, CA, and their mixtures are toxic and can induce oxidative stress in E. coli strains. The presence of wastewater affected the toxic activity and oxidative stress synthesis of these chemicals and their mixtures. The strongest toxic activity and oxidative stress generation were observed with NA at a concentration of 1 mg/dm(3) and the mixture of FLU (1 mg/dm(3)), Nor-FLU (0.1 mg/dm(3)), and NA (0.1 mg/dm(3)).

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

The introduction of Sb3+ effectively reduced the band gap of the host material and enabled energy transfer pathway for Tb3+ emission. The doped Tb3+ ions resulted in the suppression of emission due to electron transfer. The Cs2NaInCl6: 2.5 %Sb3+, 40 %Tb3+ NCs exhibited superior sensitivity and selectivity for copper ions detection.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
