Summary: A novel hybrid protein, CuST@lysozyme, composed of a superoxide dismutase-active Cu(II) complex (CuST) and lysozyme, was prepared. Spectroscopic and electrochemical analyses confirmed the binding of CuST to lysozyme. The crystal structure of CuST@lysozyme revealed the binding of the His15 imidazole group of lysozyme to the Cu(II) center of CuST. The combination of CuST with lysozyme did not decrease the superoxide dismutase activity of CuST. Based on various studies, a proposed O-2(-) disproportionation mechanism catalyzed by CuST@lysozyme was discussed.

Summary: Cu(ii) complexes with ATCUN peptide ligands were investigated for their ROS generation and oxidative DNA degradation abilities. However, the biological activity of most ATCUN complexes such as Cu-GGH (Gly-Gly-His) is low. Tuning the redox chemistry by incorporating N-heteroaromatics reinstates ROS production, leading to efficient DNA cleavage.

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: 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.
