Summary: This study systematically investigated the hydrogenation of methyl palmitate (MP) to hexadecanol over defect-rich Cu/m-ZrO2 catalysts. It was found that Cu/m-ZrO2-350 catalyst exhibited the best activity for MP hydrogenation due to its highest Cu dispersion, largest number of Cu0 sites, and surface oxygen vacancy concentration. The synergistic effect of Cu species and oxygen vacancies provides insights for the design of efficient catalysts for the conversion of fatty esters to fatty alcohols.

Summary: This study reports the development of white organic light-emitting diodes (WOLEDs) based on platinum complexes with tunable correlated color temperature (CCT). By methylating the ligand, the interaction between Pt(II) complexes was regulated, resulting in adjustable emission and CCT of the WOLEDs. High device performances with high external quantum efficiency and low efficiency roll-offs were achieved using exciplex as a host. Moreover, the CCT of the WOLEDs could be tuned by changing the driving voltages, matching with the daylight spectrum.

Summary: A biorefinery was developed to produce polyphenols, lipids, and algal biomass using olive pomace and table olive processing wastewater. Hydrolysis of the olive pomace led to the release of sugars and polyphenols, which were then recovered from the wastewater and pomace extracts using different polymeric resins. The hydrolysates were also used to produce lipids by cultivating microalgae, resulting in high productivity. I. galbana showed potential for producing polyunsaturated fatty acids.

Summary: The novel phosphorescent emitters FIr4mpic and FIr4tpic were synthesized to enhance the chromaticity and emission efficiency of the main blue phosphor FIrpic. These new emitters showed higher luminance and deeper blue light emission, with FIr4mpic achieving a maximum EQE of 18.77% and a maximum CE of 36.17 cd/A. Additionally, electronic properties were investigated using DFT calculations to explain the improved quantum yield of FIr4mpic compared to other emitters.

Summary: Ionic liquids are widely used for lipid and pigment extractions from microalgae, but their discharge into environments may pose potential risks. Evaluating the growth performance and antioxidative response of microalgae to ionic liquids can help understand stress regulation mechanisms and investigate environmental risks. Different types of ionic liquids have varying effects on the growth and oxidative stress responses of microalgae, with high concentrations leading to reductions in chlorophyll content, increases in ROS levels and malondialdehyde contents, as well as enhanced activities of superoxide dismutase in the microalgae.

Summary: Antibiotics are essential for treating bacterial infections and play important roles in aquaculture and animal husbandry, but the accumulation of antibiotics in water and soil poses global environmental risks due to excessive consumption and inadequate wastewater treatment. Toxicity studies on spiramycin, tigecycline, and amoxicillin towards Chlorella pyrenoidesa and Anabaena cylindrica reveal that the latter is more sensitive, with spiramycin and tigecycline exhibiting higher toxicity compared to amoxicillin. This research helps in assessing the ecological risks of these antibiotics on green microalgae and cyanobacteria.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
