Summary: Salen ligand L1 reacts with Ru-3(CO)(12) to form two complexes: a normal cis-beta-[Ru-II(salen)(L1)(CO)(2)] complex and a novel alkoxo-bridged dinuclear ruthenium schiff-base complex. The structures of both complexes have been determined by X-ray structure analysis. The dinuclear ruthenium complex is an efficient catalyst for intramolecular cyclopropanation of trans-alkenes.

Summary: Furanoate esters were hydrogenated efficiently using ruthenium complexes with tetradentate ligands, achieving high yield, high selectivity, and low catalyst loading. The described catalysts and reaction conditions enabled the reduction of various substituted 2- and 3-furanoate esters, where the latter had not been reduced under catalytic hydrogenation before. Additionally, different ruthenium complexes were evaluated and compared, with bis-imino complexes showing the highest versatility in terms of reactivity and selectivity.

Summary: Gold-based homogeneous catalysis is mainly achieved through AuI systems. The limited availability of AuIII catalysts for redox reactions is due to the unfavorable potentials for redox cycles between AuI and AuIII. This study presents gold(III) complexes with pincer-based PYA ligands to address these issues. The complexes act as electron reservoirs through two resonance structures, allowed by the flexible coordination sites of the ligands. The presence of a neutral L-type resonance form, as observed in solution data, prevents reversible AuIII reduction and impedes the removal of a chloride ligand. Additionally, a novel macrocyclic-PYA ligand with secondary metal-ligand interactions is introduced.

Summary: This study identified a single rhodium precursor that can achieve asymmetric full saturation of vinylarenes under both homogeneous and heterogeneous conditions. The asymmetric hydrogenation of styrenic olefins enabled by a ligand accelerated effect led to facial selectivity in consecutive arene hydrogenation. Tuning the ratio between phosphine ligand and rhodium precursor controlled the formation of catalytic species that operated without interference, showing potential for developing asymmetric arene hydrogenations.

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.
