Summary: In this study, candidate glycosyltransferase genes were screened based on the previous genome and transcriptome data of Panax notoginseng, and the full length of 27 UGT genes were successfully cloned. Among them, it was found that the PnUGT33 gene could catalyze different ginsenoside substrates to produce higher polarity rare ginsenosides. The enzymatic kinetics of PnUGT33 were analyzed and the catalytic mechanism was predicted through molecular docking simulation. Ultimately, the biosynthetic pathway of rare ginsenoside Rg(3) and gypenoside LXXV was reconstructed in yeast, and the yields were significantly improved by overexpressing UDPG biosynthetic genes.

Summary: This paper investigates the synergistic effect between molybdate and tungstate for the surface passivation of carbon steel, finding the optimal ratio of these two substances. The study shows that while the ratio of molybdate and tungstate does not affect the corrosion behavior of carbon steel, it significantly impacts its passivation behavior.

Summary: The increasing generation of e-waste poses a significant risk of REEs pollution if not properly disposed of. However, e-waste could be a secondary source for critical REEs mining. This review focuses on the selective recovery of REEs from e-waste using IL extraction as a sustainable alternative to traditional solvents. The use of ILs shows promising results in terms of extractability and selectivity, although further research is needed for real e-waste extraction efficiency and recovery rate.

Summary: The photocatalytic conversion of CO2 into solar fuels is a promising approach for green and sustainable development, but challenges remain in achieving efficient CO2RR due to slow kinetics and unfavorable thermodynamics. Surface engineering strategies, such as introducing vacancies, dopants, and cocatalysts, can enhance the activity and selectivity of CO2RR by optimizing and regulating activation and reaction pathways through surface reconstruction. This review focuses on recent advances in the rational design of semiconductor surfaces for photocatalytic CO2RR, emphasizing improved CO2 adsorption, activation, and product selectivity through theoretical calculations and in situ characterization techniques. The goal is to provide a deep understanding and rational guidance for the design of semiconductors in photocatalytic CO2RR.

Summary: The influence of heat treatment and decoration of SnO2 with gold nanoparticles on CO2 photoreduction process was analyzed. Both treatments had a deleterious effect on the reactions, with a significant drop in methane production under UV radiation. However, under visible radiation, the decorated SnO2 showed plasmonic resonance and produced methane with small amounts of carbon monoxide. These results demonstrate that the surface characteristics of SnO2 are responsible for its catalytic activity, despite its unfavorable band structure for CO2 reduction.

Summary: Glycolytic enzymes in Saccharomyces cerevisiae reorganize to form cytoplasmic foci under hypoxia, with enolase responding the fastest. Small-scale hypoxic culture systems have been shown to regulate oxygen concentration and accelerate foci formation. Screening with this method revealed that an AMPK inhibitor delayed the formation of foci in glycolytic enzymes.
