Summary: Switchable inversion of chirality between opposite handedness by varying pH is found in a histidine pendant polymer, PBHis. This phenomenon is demonstrated by circular dichroism and fluorescence correlation spectroscopy, which measure the changes of hydrodynamic radius at the single molecular level. Below pH 8.0, the polyelectrolyte adopts M-helicity, while above pH 8.0, it changes into P-helicity. Above pH 10.6, the helicity further inverses into M-chirality. The protonation and deprotonation of the imidazole group, as well as the hydroxide-ion-mediated hydrogen bonding, determine the mutual orientation and handedness of the helical structure.

Summary: In this study, soy protein isolate (SPI) was noncovalently modified by (-)-epigallocatechin-3-gallate (EGCG), leading to an improvement in its foaming, emulsifying, and antioxidant properties. The interaction between SPI and EGCG was found to involve hydrophobic force and hydrogen bonds, resulting in looser SPI structure and more active groups exposed. This modification process enhanced the functional properties of SPI significantly.

Summary: Several food dyes, including sunset yellow, can induce amyloid fibrillation in proteins such as hen egg white lysozyme (HEWL). This study found that sunset yellow dye induced fast aggregation in HEWL without a lag phase, following an isodesmic pathway. The aggregates had a cross-beta secondary structure and were affected by salts and solvents. The results suggest that electrostatic and hydrophobic interactions play a role in sunset yellow-induced amyloid fibrillation.

Summary: Interactions between sodium dodecyl sulfate (SDS) and sodium alginate (NaAlg) in aqueous salts/hydrotrope media were investigated. The study showed that the micellization of SDS and NaAlg was enhanced in aqueous electrolyte and hydrotrope media, and the formation of micelles could be delayed or accelerated depending on the temperature and solvent type. Thermodynamic calculations revealed that the micellization of SDS and NaAlg was endothermic in some solvents and exothermic in others. Hydrophobic interactions, van der Waals forces, and exothermic reactions were identified as the driving forces between SDS and NaAlg in electrolyte and hydrotrope media.

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.
