In clean, one-pot procedures, the uranium complex 1 reductively cleaves azides and azo compounds to generate bis(imido) derivatives [Eq. (a)]. This unusual reaction has not been observed previously in either actinide series or with a metallocene complex.
The Bergman cyclization has been the subject of renewed interest with discovery naturally occurring enediyne-based antitumor agents that cleave DNA by means an aromatic diradical. These natural substrates have a to trigger this cycloaromatization process. Control reaction substrate modification would allow diradicals be generated selectively. In studies presented here it is disclosed 1,2-bis(diphenyl phosphinoethynyl) benzene was accelerated factor >30,000 addition palladium(II) chloride or...
AbstractWe provide an overview of research in sustainability education. We argue that the interconnectedness environmental programs at K–12 schools is one metric by which education can be conceptualized. present a new measure whole-school sustainability, or "interconnectedness," and then use it to compare U.S. Department Education Green Ribbon Schools. In total, we 59 different schools, with total 289 projects. Finally, analysis differences between are certified as sustainable. Using results...

There is a need for specific knowledge of what people can do to mitigate harmful water conflicts. This evident in the rural dry tropics Central America where face climate change impacts, inefficient management, and social tension. To address this need, we investigated why some local conflicts escalated violence other potential were avoided Guanacaste Province, Costa Rica. We used interviews, focus groups, stakeholder workshop analyse five cases. found that violent actions only occurred when...
Beryllium is widely used in industry for its unique properties; however, occupational exposure to beryllium particles can cause potentially fatal disease. Consequently, limits air and action levels on surfaces have been established reduce risks workers. Field-portable monitoring methods are desired order facilitate on-site measurement of the workplace, so that immediate be taken protect human health. In this work, a standardized, portable fluorescence method determination trace workplace...
Understanding landowner perspectives on flood mitigation is an essential step towards minimising conflict and ensuring public support compliance. To illuminate the drivers of those perspectives, we surveyed landowners in Deerfield River Watershed, Massachusetts ( USA ). Confirmatory factor analysis shows differentiate between physical policy pathways through which strategies provide protection. Multiple regression analyses indicate or opposition for each related both to risks a faces their...

N-Substituted glycine peptoid oligomers have recently attracted attention for their metal binding capabilities. Due to efficient synthesis on solid phase, peptoids are well suited generation of compound libraries, followed by screening molecular recognition and other diverse functional attributes. Ideally, could be simultaneously screened a number species. Here, we demonstrate the use bench-top X-ray fluorescence (XRF) instrumentation screen rapidly, support, library incorporating...
