3D printable diffractive optical elements by liquid immersion
12hNature Communications, Published online: 24 May 2021; doi:10.1038/s41467-021-23279-6 Diffractive optical elements are broadly used due to their ability to reshape the wavefront efficiently and conveniently. By using liquid immersion, the authors here enable microscale 3D-printed optics to behave like nanoscopic structures while maintaining high performance.
Electrochemical C−C bond cleavage of cyclopropanes towards the synthesis of 1,3-difunctionalized molecules
12hNature Communications, Published online: 24 May 2021; doi:10.1038/s41467-021-23401-8 Electrochemical oxidative C–C bond cleavage and functionalization are rarely developed due to the inertness and weak electronic bias of C–C bonds. In this study, the authors report the electrochemical C–C bond cleavage and 1,3-difluorination, 1,3-oxyfluorination and 1,3-dioxygenation of arylcyclopropanes under ca

All-dielectric chiral-field-enhanced Raman optical activity
12hNature Communications, Published online: 24 May 2021; doi:10.1038/s41467-021-23364-w Raman optical activity (ROA) is useful for studying conformational structure and behavior of chiral molecules, but is limited by the weak signals. Here, the authors demonstrate 100x signal enhancement via an all-dielectric approach, using a silicon nanodisk array and exploiting its dark mode.
Construction 7-membered ring via Ni–Al bimetal-enabled C–H cyclization for synthesis of tricyclic imidazoles
12hNature Communications, Published online: 24 May 2021; doi:10.1038/s41467-021-23371-x Transition metal-catalyzed C−H cyclization for medium-ring synthesis has been limited to reactive C−H bonds, the activation of unreactive C−H bonds still remains a challenge. Here the authors show the direct construction of 7-membered rings via Ni−Al co-catalyzed unreactive C−H cyclization of benzoimidazoles with

Obesity and cancer: Studies highlight different aspects of the connection
14hMulti-factorial metabolic and inflammatory abnormalities in obesity, independently or in combination, seems to be the critical biological link of obesity, cancer and racial/gender health disparities. However, the specific cross-talk between these factors remain elusive. Because of the extraordinary relevance in understanding the relationship between obesity-associated inflammation and comorbiditie
Weight-loss maintainers sit less than weight-stable people with obesity
