Summary: In this study, highly functionalized porous metalloporphyrin complexes [In(p-X4TPP)Cl] (X = Cl, Br) were synthesized using a catalyst-free coupling technique and employed as efficient dye adsorbents. The morphology and structure of the synthesized complexes were determined using scanning electron microscopy, powder X-ray diffraction, Fourier transform infrared, proton nuclear magnetic resonance, elemental analysis, and ultraviolet-visible spectroscopy. The efficacy of the complexes in removing cationic dyes was evaluated by studying the adsorption of methylene blue dye. The adsorption kinetics followed the pseudo-second-order model, and the adsorption isotherm was described by the Langmuir model, with Qmax values of 80.4386 and 88.060 mg.g -1, respectively. The adsorption mechanism involved electrostatic interactions, high specific surface area, X center dot center dot center dot X interactions, and strong pi-pi interaction between In(III)chloride complexes and methylene blue dye.

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.
