Summary: We report the formation of NHC complexes of mono- and bis-hydrazino boranes with N-N-B and N-N-B-N-N chains via the reaction of NHC-boranes with electrophilic azo reagents. Steric hindrance on the carbene (primarily) and on the azo reagent (somewhat less) is crucial for the reactivity. Bis-hydrazino borane complexes with two different hydrazine arms could be obtained via sequential additions.

Summary: New monomethine, unsymmetrical styryl dyes consisting of benzothiazole and N-methylpiperazine or N-phenylpiperazine scaffolds were synthesized and studied for their binding affinities for different ds-polynucleotides and G-quadruplex. The substitution of piperazine unit strongly influenced their binding modes, affinities, spectroscopic responses, and antiproliferative activities. N-methylpiperazine-substituted compounds showed a preference for AT-DNA polynucleotides and demonstrated AT-minor groove binding, while N-phenylpiperazine substituted compounds showed stronger stabilization of G-quadruplex. Fluorimetric titrations suggested possible mixed stoichiometries with G-quadruplex. Compounds with N-phenylpiperazine fragments exhibited micromolar and submicromolar antiproliferative activity, particularly against leukemia and lymphoma.

Summary: In this study, the self-assembly of N-heterocyclic olefins (NHOs) on gold surface was investigated using experimental and computational methods. It was found that NHOs can self-assemble into dimers, trimers, and tetramers, forming stable monolayers. The study also revealed that NHOs can adsorb on gold surface in a flat-lying geometry through coordination with gold adatoms, and the surface interaction can be further increased by functionalizing the backbone with methyl groups, leading to enhanced thermal stability and impact on work-function values.

Summary: This study used spectroscopic techniques and molecular docking to investigate the interaction mechanisms between bovine serum albumin (BSA) and two newly synthesized azo dyes. The results showed that the dyes formed complexes with BSA, leading to quenching of fluorescence emission. UV-Vis spectroscopy confirmed conformational and micro environmental changes of BSA upon complex formation. Thermodynamic calculations indicated spontaneous binding of the dyes to BSA, with van der Waals force and hydrogen bonding playing a major role in the process. Molecular docking studies revealed the probable binding site of the dyes on subdomain IB of BSA through hydrophobic interaction and hydrogen bond. Additionally, the dyes induced conformational changes in BSA, altering its biological functions.

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.

Summary: This study synthesized Cs2NaInCl6 nanocrystals co-doped with Sb3+ and Tb3+ ions as probes for copper ions detection in lubricating oil. 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.
