Summary: A highly selective and sensitive receptor for Al3+ and Cu2+ ions was synthesized and characterized. The receptor exhibited solvatochromism and keto-enol tautomerism properties in different solvents. It was found to be a highly selective colorimetric sensor for Al3+ ions, and a turn-off sensor for Cu2+ ions. The highlight of this work is its effectiveness as a naked-eye sensor for both Al3+ and Cu2+ ions.

Summary: A simple Schiff base sensor, NNM, was used for chemosensing metal ions. The sensor showed a red shift in absorption spectra and quenching in the emission band in the presence of Cu2+ and Ni2+ ions. The stoichiometry of NNM for the analytes was found to be 1:1. The system demonstrated nanomolar detection of Cu2+ and Ni2+ ions and could be highly applicable in environmental and biological applications.

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.
