摘要:Improved stability and efficiency of two-terminal monolithic perovskite-silicon tandem solar cells will require reductions in recombination losses. By combining a triple-halide perovskite (1.68 electron volt bandgap) with a piperazinium iodide interfacial modification, we improved the band alignment, reduced nonradiative recombination losses, and enhanced charge extraction at the electron-selective contact. Solar cells showed open-circuit voltages of up to 1.28 volts in p-i-n single junctions ...

摘要:The Hubbard model of attractively interacting fermions provides a paradigmatic setting for fermion pairing. It features a crossover between Bose-Einstein condensation of tightly bound pairs and Bardeen-Cooper-Schrieffer superfluidity of long-range Cooper pairs, and a pseudo-gap region where pairs form above the superfluid critical temperature. We directly observe the nonlocal nature of fermion pairing in a Hubbard lattice gas, using spin- and density-resolved imaging of similar to 1000 fermion...

摘要:New methods are emerging to quantify human and animal welfare on a common scale, creating new tools for policy There is growing international consensus that animal welfare is a crucial consideration in policy analysis, affecting domains ranging from food systems to biomedical research. Concern for animal welfare also features in many government regulations, certification programs, and institutional ethics codes across the globe and is central to many philanthropic and values-based investment d...

摘要:Nanoscale chromatin organization regulates gene expression. Although chromatin is notably reprogrammed during zygotic genome activation (ZGA), the organization of chromatin regulatory factors during this universal process remains unclear. In this work, we developed chromatin expansion microscopy (ChromExM) to visualize chromatin, transcription, and transcription factors in vivo. ChromExM of embryos during ZGA revealed how the pioneer factor Nanog interacts with nucleosomes and RNA polymerase I...

摘要:Silicon solar cells are approaching their theoretical efficiency limit of 29%. This limitation can be exceeded with advanced device architectures, where two or more solar cells are stacked to improve the harvesting of solar energy. In this work, we devise a tandem device with a perovskite layer conformally coated on a silicon bottom cell featuring micrometric pyramids-the industry standard-to improve its photocurrent. Using an additive in the processing sequence, we regulate the perovskite cry...

摘要:Idon't think industry would be a good fit for me, the student said, I'm not money-motivated. As an industry scientist myself, I struggled to hide my surprise. I was participating in a conference event to help graduate students and postdocs explore career options by connecting with professionals across industry, academia, government, and nonprofits. I love my work, and I was excited to share it with the attendees. Overall, they were enthusiastic to learn about their options, and some were seri...

摘要:Gut-brain connections drive the motivation to work out Exercise is arguably the most potent and attainable lifestyle factor that individuals can use to safeguard themselves against a large variety of diseases, including metabolic, cardiovascular, neurodegenerative, and neoplastic diseases (1). Despite its vast health benefits, only a small fraction of the population adheres to the World Health Organization's recommendation of 150 to 300 minutes of moderate-intensity exercise per week (2). Busy...
