Developing highly efficient non-iridium-based active sites for acidic water splitting is still a huge challenge. Herein, unique Ru-B-Cr moieties have been constructed in RuO nanofibers (NFs) to activate Ru sites for water electrolysis, which overcomes the bottleneck of RuO-based catalysts usually possessing low activity for the hydrogen evolution reaction (HER) and poor stability for the oxygen evolution reaction (OER). The fabricated Cr, B-doped RuO NFs exhibit low overpotentials of 205 and 379 mV for acidic HER and OER at 1 A cm with outstanding stability lasting 1000 and 188 h, respectively.
NAC [NO APICAL MERISTEM (NAM), ARABIDOPSIS TRANSCRIPTION ACTIVATOR FACTOR 1/2 (ATAF1/2), and CUP-SHAPED COTYLEDON (CUC2)] transcription factors are key regulators of plant growth, development, and stress responses but were also crucial players during land plant adaptation and crop domestication. Using representative members of green algae, bryophytes, lycophytes, gymnosperms, and angiosperms, we expanded the evolutionary history of NAC transcription factors to unveil the relationships among members of this gene family. We found a massive increase in the number of NAC transcription factors from green algae to lycophytes and an even larger increase in flowering plants.
Objectives: Urothelial carcinoma in situ (CIS) with early papillary formation is terminology sometimes used to suggest incipient high-grade papillary urothelial carcinoma (PUC) but may lead to confusion between true CIS and lateral flat spread of PUC.
Methods: It remains unclear how pathologists and urologists interpret this scenario, so a survey was circulated to 68 pathologists (group 1 = 28 academic genitourinary pathologists; group 2 = 17 pathologists with a self-reported genitourinary focus; group 3 = 23 pathologists self-reported as not genitourinary specialists) and 32 urologists.
Results: Regarding atypical urothelial lesions that appear mainly flat but contain possible papillae, group 3 was more likely to label this as CIS compared with groups 1 and 2 (35% for group 3 vs 13% for groups 1 and 2), while groups 1 and 2 more often adopted another descriptive diagnosis, such as "CIS with early papillary features" (38% for groups 1 and 2 vs 13% for group 3).
Microplastics (MPs) are a growing problem worldwide. Soils are long-term storage sinks of MPs because of the many pathways they enter the soil and their long degradation period. Knowing how MPs influence soil organisms, the effects of organisms on the fate of MPs, and what this means for soil additions, losses, transformations, and translocations is paramount.
Ambrosia beetles (Curculionidae: Scolytinae and Platypodinae) are fungus-farming woodborers that can cause damage to the trees they colonize. Some of these beetles target stressed plants that emit ethanol, and management strategies have proposed using ethanol-injected trees as trap trees to monitor or divert dispersing adult females away from valuable crops. In this study, we used container-grown trees from 8 species to compare the effect of ethanol injection versus flooding on ambrosia beetle host selection and colonization success.
