Summary: Jujube is a light-demanding fruit tree, but weak light in protected cultivation facilities can degrade fruit quality. This study used a black shade net to artificially set three light intensities and found that low light suppressed sugar metabolism in jujube, mainly due to down-regulated expression of genes related to sucrose synthesis.

Summary: This study evaluated the effects of Aloe vera gel (AV) and modified atmosphere packaging (MAP) treatments on the quality of jujube fruit during cold storage and shelf life. The results showed that MAP treatment delayed weight loss and respiration rate, increased firmness and acidity, and improved vitamin C, phenol, flavonoid, and antioxidant activity levels. However, it decreased chroma and soluble solids content. AV and MAP treatments both enhanced the fruit quality during shelf life, with MAP treatment having a more pronounced effect.

Summary: This study investigated the regulation mechanism of propyl gallate (PG) on the post-harvest quality of winter jujube fruits from the perspective of antioxidant metabolism and peel structure. The results showed that PG treatment delayed the development of peel color, improved fruit firmness and total soluble solids (TSS), increased the content of total phenols, total flavonoids, ascorbic acid (AsA), and reduced glutathione (GSH), and maintained the activity of several enzymes at a higher level. Furthermore, PG treatment reduced membrane oxidative damage and maintained the integrity of the pericarp structure. The appropriate concentration of PG has the potential to improve the storage and preservation of fresh fruits such as winter jujube.

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: This study synthesized Cs2NaInCl6 nanocrystals co-doped with Sb3+ and Tb3+ ions as probes for copper ions detection in lubricating oil. 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.
