“…Conversely, in the nitride-bridged diuranium(iv) complex supported by –OSi(O(t)Bu)(3) ligands, the nitride group is easily protonated to afford NH(3), which binds the U(iv) ion strongly, resulting in a mononuclear U–NH(3) complex, where NH(3) can be displaced by addition of strong acids. …”

“…The quantification of u-MTBE, u-ETBE, u-TAME, and u-DIPE was performed by HS-SPME-GC/MS technique and information on participants was collected by a questionnaire. u-DIPE concentrations resulted always under the LOQ. u-TAME mean levels were similar in both seasons (18.7 ng L(−1) in summer vs. 18.9 ng L(−1) in winter), while u-MTBE and u-ETBE levels were, respectively, 69.9 and 423.5 ng L(−1) (summer) and 53.3 and 66.2 ng L(−1) (winter). …”

“…Prokaryotic similarities increased over geographic distance after tipping points of 1760–1920 km, generating a significant U-shape pattern. Such pattern was likely due to decreased disparities in environmental heterogeneity over geographic distance when across biotas, supported by three lines of evidences: (1) prokaryotic similarities still decreased with the environmental distance, (2) environmental selection dominated prokaryotic assembly, and (3) short-term environmental heterogeneity followed the U-shape pattern spatially, especially attributed to dissolved nutrients. …”

“…The appearance of the pre-edge peaks from U to Pu and their relative intensities are rationalized simply by the energetic separation of transitions to 6d t(2g)versus transitions to weakly-bonded and strongly stabilized a(2u), t(2u) and t(1u) orbitals with 5f character. …”

“…Current estimates of U.S. property at risk of coastal hazards and sea level rise (SLR) are staggering—evaluated at over a trillion U.S. dollars. Despite being enormous in the aggregate, potential losses due to SLR depend on mitigation, adaptation, and exposure and are highly uneven in their distribution across coastal cities. …”
