Summary: This study investigated the use of gastropoda shells as a calcium source for the synthesis of hydroxyapatite (HAP), and found that the biogenic HAP derived from these shells had poor antibacterial properties. To improve the antibacterial property, Musa paradisiaca sap was added to the formation of a biocomposite with HAP. The results showed that the nano-HAP/M. paradiasica sap biocomposite had a controlled shape and exhibited higher resistance against bacterial growth. The in vitro cell viability assay confirmed the biocompatibility of the synthesized biocomposite.

Summary: Natural (Caprine bone) Hydroxyapatite/Phyllanthus acidus and Gallium substituted Hydroxyapatite/Phyllanthus acidus composite powders were successfully synthesized by thermal decomposition method. The synthesized powders were characterized for functional groups, phase purity, and crystalline size. The results showed that the substitution of Gallium led to a reduction in the size of Hydroxyapatite powders, resulting in finer powders and a uniform surface morphology. Gallium substituted Hydroxyapatite/Phyllanthus acidus composite exhibited better antibacterial activity compared to Hydroxyapatite/Phyllanthus acidus composite.

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.
