High entropy alloys（HEAs）, known for their synergistic orbital interactions among multiple elements, have been recognized as promising electrocatalysts for enhancing the sluggish kinetics of oxygen evolution reaction（OER）. Despite their potential, the facile and rapid preparation of HEA nanoparticles（NPs） with high electrocatalytic activity remains challenging. Here, we report an ultrafast synthesis of noble-metal-free FeCoMnCuAl HEA NPs loaded on conductive carbon fiber networks using a Joule heating strategy. The prepared HEA NPs exhibited a face-centered cubic（FCC） structure with an average size of approximately 25 *** X-ray absorption fine structure（XAFS） and X-ray photoelectron spectroscopy（XPS） studies were performed to investigate the atomic and electronic structures of the HEA NPs, revealing the co-presence of Fe, Co, Mn, Cu and Al elements as well as their different valences across surface and internal regions. The HEA NPs showed remarkable OER performance, exhibiting an overpotential of 280 mV at 10 mA cm-2and a low Tafel slope of 76.13 mV dec-1in a 1.0 M KOH solution with high electrochemical stability, superior to commercial RuO2electrocatalysts. This work provides a new approach for synthesizing nanoscale noble-metal-free HEA electrocatalysts for clean energy conversion applications on a large-scale basis for practical commercialization.

Flooding is an abiotic stress that impacts soybean [Glycine max (L.) Merr.] growth and reduces seed germination. Effect of flooding on soybean plant grown at different growth stage has been previously conducted and reported. However, soybean seed germination responses to flood stress are largely unknown. The objective of this study was to elucidate flooding influence on soybean seed germination after planting in the field. The research showed that seed germination rate (SGR) of each genotype, without flood stress, was significantly different and ranged between 64.7% to 84.0% and 69.0% to 90.7% while using untreated and fungicide-treated seed (P < 0.0001), respectively. Results indicated that fungicide treatment improved soybean seed survival and germination in the field. The average of SGR of high-yielding soybean group was significantly higher than those of non-high-yielding soybean (P < 0.0001). The results indicated that high-yielding trait of each genotype was correlated with seed germination and survival. Under flood stress in the field, SGR means of untreated and fungicide-treated seed significantly decreased over eight flooding treatment times (P Flooding effect on germination between untreated and fungicide-treated seed was not significantly different (P = 0.1559). Furthermore, comparing the high-yielding and flood-tolerant soybean groups showed no difference in their SGR means over eight flooding treatment times (P = 0.7687 and P = 0.8490), indicating that soybean seed germination did not depend on genotype, yield, and flood tolerance trait, and seed treated by fungicide did not increase its germination in the field under the flood stress. Hence, it is necessary to develop new soybean seed pelleting to improve seed germination in the field under flooding conditions.

Fruit of Lonicera caerulea L. is a rich source of phenolic compounds such as phenolic acids as well as anthocyanins,proanthocyanidins and other flavonoids,which display potential health-promoting effects. However,its genetics and genomic information is limited. Transcriptome and digital gene expression( DGE) profiles of fruit at four different development stages were compared. Related genes with anthocyanin biosynthesis were compared using real-time quantitative PCR( qRT-PCR). RNA-Seq generated 6. 26-Gb clean reads,which was then de novo assembled into 45,656 UniG enes with a mean length 837 bp. A total of 7 928 unigenes were annotated into 32 known metabolic or signaling pathways in which a few primary,intermediate,and secondary metabolic pathways are directly related to fruit quality. The result of DGE and qRT-PCR indicates that UFGT( comp20132_c0) may play a key role in honeysuckle coloration. This provides a reference for the study of complicated metabolism in non-model perennial species.
