Summary: Selenium (Se) is a crucial nutrient in human physiology and immune function, and supplementing bioavailable Se can be beneficial for human health. The Antrodia camphorata mushroom, native to Taiwan, can assimilate and transform sodium selenite into organic selenium. The study found that the organic selenium content accounted for 88.1% of the total selenium content in selenium-enriched A. camphorata mycelia, and selenium-enriched polysaccharide was the main form of Se present in the mushroom. The selenium-enriched polysaccharides also showed a significant improvement in antioxidant capacity.

Summary: In this study, glycol lignins (GLs) were synthesized via acid-catalyzed solvolysis of softwood meal using monomethyl ethers of polyethylene glycol (MPEG). The yield, molecular weight, and thermal properties of MPEG-lignin were studied under different reaction times and temperatures. The results showed that the yield of MPEG-lignin increased with solvolysis time, and acid-catalyzed solvolysis using MPEG-n4 occurred faster than that using MPEG-n8. Higher reaction temperature resulted in a higher yield of MPEG-lignin with increased glass transition temperature (T9) and viscous thermal flow temperature (Ti).

Summary: The structures and characteristics of lignin derivatives prepared from steam exploded beech under alkali delignification and acid catalyzed polyethylene glycol (PEG) solvolysis were studied in detail. An efficient method for directly isolating PEG-modified lignin from wood was proposed to improve its thermal stability. The effects of steam explosion (SE) parameters and delignification process on lignin structure were studied, and it was found that SE pretreatment can greatly promote the yield of PEG-modified lignin and improve its thermal properties.

Summary: The dielectric constant of water/oligomer mixtures was investigated using molecular dynamics simulations. The results show that the dielectric constant decreases as the water content decreases, but does not follow ideal mixing behavior. This deviation is primarily due to the non-linear relationship between the oligomer mass fraction and collective polarization effects. The study also found that water polarization dominates the dielectric constant, even when the oligomer mass fraction exceeds 50%.

Summary: Concerns have been raised about the impacts of fossil fuel combustion on global warming and climate change. Microalgae fuel, as a potential source of energy diversification, is gaining popularity in the aviation industry. It can grow in saltwater or wastewater, capture CO2, and produce lipids without threatening food availability. Microalgae-derived fuels have a low carbon footprint and the potential to mitigate the impact of traditional aviation fuels on climate change and global warming. However, there are challenges such as high production costs and limited research in this field.

Summary: Organic wastewater is a major cause of environmental pollution and catalytic oxidation is a promising technique for wastewater treatment. However, developing green and effective catalysts poses a challenge. In this study, a green synthesis method was used to load nano zero-valent iron onto porous biochar derived from popcorn. The catalytic oxidation of Rhodamine B (RhB) in the presence of H2O2 was evaluated, and the effect of process factors on catalytic performance was examined. The results showed that high catalyst dosage, low initial RhB concentration, and high reaction temperature improved RhB removal. The carbonization temperature of biochar, H2O2 dosage, and pH value had a slight influence on RhB removal. The study also discussed the mechanism of RhB removal through various characterizations and UV-vis spectra analysis. The findings provide valuable insights into the use of green catalysts for catalytic oxidation of organic wastewater.
