摘要:C-N bond formation is integral to modern chemical synthesis owing to the ubiquity of nitrogen heterocycles in small-molecule pharmaceuticals and agrochemicals. Alkene hydroamination with unactivated alkenes is an atom-economical strategy for constructing these bonds. However, these reactions are challenging to render asymmetric when preparing fully substituted carbon stereocentres. Here we report a photoenzymatic alkene hydroamination to prepare 2,2-disubstituted pyrrolidines by a Baeyer-Villi...

摘要:Frictional motion is mediated by rapidly propagating ruptures that detach the ensemble of contacts forming the frictional interface between contacting bodies(1-7). These ruptures are similar to shear cracks. When this process takes place in natural faults, these rapid ruptures are essentially earthquakes(8,9). Although fracture mechanics describe the rapid motion of these singular objects, the nucleation process that creates them is not understood(10-19). Here we fully describe the nucleation ...

摘要:Pre-eclampsia is a placental disorder that affects 3-5% of all pregnancies and is a leading cause of maternal and fetal morbidity worldwide(1,2). With no drug available to slow disease progression, engineering ionizable lipid nanoparticles (LNPs) for extrahepatic messenger RNA (mRNA) delivery to the placenta is an attractive therapeutic option for pre-eclampsia. Here we use high-throughput screening to evaluate a library of 98 LNP formulations in vivo and identify a placenta-tropic LNP (LNP 55...

摘要:Lithium (Li) metal batteries (LMBs) are promising for high-energy-density rechargeable batteries(1-3). However, Li dendrites formed by the reaction between highly active Li and non-aqueous electrolytes lead to safety concerns and rapid capacity decay(4-7). Developing a reliable solid-electrolyte interphase is critical for realizing high-rate and long-life LMBs, but remains technically challenging(4,8). Here we demonstrate that adding excess m-Li2ZrF6 (monoclinic) nanoparticles to a commercial ...

摘要:In medicine, a person's blood-test results are compared with the average range in a population. But results are highly individual and tightly regulated around a person's own stable values. Changes to these values can indicate disease.

摘要:Our understanding of type 2 immunity has undergone a substantial transformation in recent years, revealing previously unknown functions. Beyond its canonical role in defence against parasitic helminth infections, type 2 immunity safeguards the host through additional mechanisms, including the suppression of excessive type 1 immune responses, regulation of tissue repair and maintenance of adipose tissue homeostasis. However, unlike type 1 immune responses, type 2 immunity is perceived as a pote...
