Summary: The high biological toxicity of mercury ion (Hg2+) has had a negative impact on society, necessitating the development of a rapid Hg2+ detection method. In this study, two fluorescent probes, YF-Hg and YF-Cl-Hg, were developed. YF-Cl-Hg, with an electron-withdrawing substituent (-Cl), exhibited a larger Stokes shift and a more pronounced UV-vis absorption redshift compared to YF-Hg in a pH = 7.4 environment. The reasons for the superior spectral performance of YF-Cl-Hg were explored using density functional theory (DFT) calculations and UV-vis absorption spectroscopy. Furthermore, the good biocompatibility of YF-Cl-Hg suggests its potential as a tool for Hg2+ detection in cells.

Summary: Transition metal ions play crucial roles in medicine, life sciences, and environmental science, but some like mercury, copper, and iron ions pose serious health and environmental risks due to biomagnification. Monitoring metal ion levels in organisms and the environment is urgent, and reaction-based fluorescent probes offer higher sensitivity and selectivity than traditional methods. Research on these probes for Hg2+, Cu2+, and Fe2+/Fe2+ detection has advanced in the past decade, with potential for interdisciplinary development in the future.

Summary: A novel fluorescent probe (TO-PCBM) based on flavonol and thiocarbonate was synthesized for turn-on monitoring of Hg2+. The probe exhibited sensitive detection, low limit of detection, large Stokes shift, and fast response. The unique sensing mechanism involved the deprotection of thiocarbonate induced by Hg2+, resulting in the emission of strongly excited state intramolecular proton transfer of MHPCB. The probe showed high recovery rate in real environmental water samples and successfully monitored Hg2+ in fluorescence imaging of zebrafish and onion cells.

Summary: In this study, a selective fluorescent probe called ICM-Hg was successfully designed and synthesized for the detection of Hg2+ in real samples and intracellular staining. ICM-Hg displayed high specificity toward Hg2+ through the activation of intramolecular charge transfer (ICT) process, resulting in a distinct color change and enhanced yellow fluorescence emission. The fluorescent intensity of ICM-Hg showed a linear relationship with Hg2+ concentration (0-45 μM), with a detection limit of 231 nM. Furthermore, ICM-Hg demonstrated efficient detection of Hg2+ in real samples such as tap water, tea, shrimp, and crab, as well as intracellular fluorescence imaging.

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.
