Summary: In this study, the dielectric properties and dielectric breakdown strength (DBS) of PbO-B2O3-SeO2:Ho2O3 (PBSH) glass ceramics were investigated as a function of Au2O3 content. It was found that an increase in Au2O3 content resulted in an increase in structural imperfections, leading to an increase in space charge polarization and dielectric constant. Furthermore, the increase in Au2O3 content was also found to enhance the polaronic exchange between two structural groups of SeO2, resulting in an increase in ac conductivity.

Summary: Li2O-HfO2-SiO2-Tm2O3:Au2O3 glass samples with fixed Tm2O3 content and varying Au2O3 concentration were prepared and characterized. The influence of Au-0 metallic particles on the blue emission of Tm3+ ions was investigated. Optical absorption spectra revealed multiple bands excited from the H-3(6) level of Tm3+ ions, and a broad peak in the 500-600 nm range due to surface plasmon resonance of Au-0 metallic particles. Photoluminescence spectra of Tm3+ and Au2O3 co-doped glasses showed intense blue emission, which increased with higher Au2O3 content. The enhancement of blue emission by Au-0 metallic particles was discussed in detail using kinetic rate equations.

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.
