  摘要：Van der Waals encapsulation of two-dimensional materials in hexagonal boron nitride (hBN) stacks is a promising way to create ultrahigh-performance electronic devices(1-4). However, contemporary approaches for achieving van der Waals encapsulation, which involve artificial layer stacking using mechanical transfer techniques, are difficult to control, prone to contamination and unscalable. Here we report the transfer-free direct growth of high-quality graphene nanoribbons (GNRs) in hBN stacks. ...

• Optical clocks at sea AI翻译
  作者：Roslund, Jonathan D.; Cingoez, Arman; Lunden, William D.; Partridge, Guthrie B.; Kowligy, Abijith S.; Roller, Frank; Sheredy, Daniel B.; Skulason, Gunnar E.; Song, Joe P.; Abo-Shaeer, Jamil R.; Boyd, Martin M.
  摘要：Deployed optical clocks will improve positioning for navigational autonomy 1 , provide remote time standards for geophysical monitoring 2 and distributed coherent sensing 3 , allow time synchronization of remote quantum networks 4,5 and provide operational redundancy for national time standards. Although laboratory optical clocks now reach fractional inaccuracies below 10-18 (refs. 6,7 ), transportable versions of these high-performing clocks 8,9 have limited utility because of their size, env...

  摘要：Vertebrate organs require locally adapted blood vessels 1,2 . The gain of such organotypic vessel specializations is often deemed to be molecularly unrelated to the process of organ vascularization. Here, opposing this model, we reveal a molecular mechanism for brain-specific angiogenesis that operates under the control of Wnt7a/b ligands-well-known blood-brain barrier maturation signals 3-5 . The control mechanism relies on Wnt7a/b-dependent expression of Mmp25, which we find is enriched in b...
