Summary: A novel optical chemosensor, CM1, was designed and synthesized and characterized by H-1-NMR and FT-IR spectroscopy. CM1 showed efficient and selective sensing towards Cd2+ even in the presence of other metal ions. The formation of Cd2+-CM1 complex was confirmed through fluorescence emission spectrum, fluorescent titration, Job's plot, and DFT calculation. CM1 exhibited high sensitivity towards Cd2+ with a low detection limit of 19.25 nM. The chemosensor could be recovered and recycled by the addition of EDTA solution.

Summary: Poly(ionic liquids) (PILs) have been widely used for CO2 capture due to their resemblance to ionic liquids and properties of polymers. In this study, the amine-functionalized poly(vinylimidazole)-based PIL (PVIm-NH2) was successfully prepared and characterized as a chemosensor for CO2 gas detection. The detection limit of PVIm-NH2 in the presence of triethylamine (TEA) was found to be 2.86 x 10-3 M with R2 = 0.9906. The mechanism of PVIm-NH2 generating N-heterocyclic carbenes (NHCs) in the presence of TEA and their reaction with CO2 gas to form a carboxylic acid was investigated. Structural modifications of PIL were also shown to make it a promising candidate for chemosensor applications.

Summary: A novel coumarin-thiol chemosensor L has been designed and prepared for sequential colorimetric and fluorescent detection of mercury (II) and cyanide ions in aqueous solution. The probe L shows high selectivity and sensitivity towards mercury (II) cations, and forms a complex L/Hg2+ which exhibits red-shift and fluorescence quenching. In turn, the complex L/Hg2+ shows high selectivity for cyanide anions. A test paper was also developed for simultaneous detection of mercury (II) and cyanide ions in pure water without the need for additional equipment.

Summary: Atom- and step-economy in IBX-assisted diversity-oriented synthesis is achieved with a versatile AQ auxiliary alpha-amino acid analogs, offering rapid access to polycyclic spiro-quinolines featuring a quaternary stereocenter in 20%-91% yields under mild conditions via 7,8-dearomatization of quinolines. The highlight of this intramolecular oxidation spiroannulation tandem reaction is the absence of a preinstalled activation group. These traditionally difficult-to-access N-heterospirocycles may provide a potentially interesting scaffold for synthetic and medicinal chemistry.

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.
