摘要：Organic self-assembled molecules (SAMs), which are widely used in perovskite solar cells (PSCs), should exhibit enhanced performance to support the ongoing advancement of perovskite photovoltaics. We designed diradical SAMs through a coplanar conjugation of a donor-acceptor strategy to facilitate hole transport across the SAMs. The diradical SAMs exhibited high photothermal and electrochemical stability as well as improved assembly uniformity and large-area solution processability attributed t...

摘要：The Qimmeq (Greenland sled dog) has worked continuously with the Inuit in Greenland for more than 800 years. However, they now face drastic population declines caused by climate change, urbanization, and competition from snowmobiles. This study sequenced 92 modern and ancient genomes to investigate how centuries of isolation shaped the regional Qimmeq populations and the impact of European contact. We found distinct regional populations and evidence for two migrations of dogs into Greenland wi...

摘要：Metal carbenes are highly useful intermediates in organic synthesis. However, not all classes of carbene polarity are catalytically accessible, nor are there common precursors known to synthesize all of these electronically diverse carbene types. Here, we report a unified strategy to access a full range of carbenes, including those with donor substituents (EDG: OMe, NR2, alkyl), acceptor substituents (EWG: CN, CO2R), and electronically neutral or nonpolar substituents (H, BR2, SiR3, halide, ar...
