摘要：Wurtzite ferroelectrics could provide a route to wafer-scale integrated ferroelectric memories but are limited by endurance, typically failing at similar to 10(8) cycles. We identified nitrogen-vacancy (V-N) clustering and long-range percolative migration as the defect-mediated pathways that drive leakage-current growth and dielectric breakdown. We combined a spatially engineered aluminum scandium nitride/aluminum nitride (AlScN/AlN) superlattice with a dynamic recovery protocol to spatially a...

摘要：Nanotubes represent an important class of crystalline materials, but controlling their structures, particularly chiralities, remains a fundamental challenge. In this work, we report a strategy for synthesizing transition metal dichalcogenide nanotubes with preferred armchair chirality. Tin disulfide, molybdenum disulfide, and tungsten disulfide nanotubes were formed with high yield and structural purity inside boron nitride nanotube channels. Atomic-resolution imaging, electron diffraction, an...

摘要：M & ouml;ssbauer spectroscopy is widely used in chemistry, geology, and solid-state physics to probe the local physical and chemical environment of nuclei in materials. Here, we extended this technique into the optical range using a vacuum ultraviolet laser to probe the low-energy nuclear transitions of thorium-229 (229Th) doped in calcium fluoride (CaF2) crystals. We discovered four distinct doping sites for the thorium ions, determined the characteristic electric field gradients emerging fro...

摘要：Prior expectations guide attention and support perceptual filtering during decision-making. In mice performing a visual discrimination task, choices depended on trial-by-trial differences between consecutive stimuli (|Delta Dir|). We hypothesized that thalamic lateral posterior (LP; rodent pulvinar) projections to prefrontal areas such as the anterior cingulate cortex (ACC), previously implicated in selective attention and predictive processing, could support history-dependent evaluation of cu...

摘要：In film-substrate systems, the substrate role is often considered to be limited to providing static mechanical constraints. Dynamic film-substrate interactions when a structural change in the film modifies the substrate are generally disregarded. Using combined x-ray and electron microscopies, we observed that an electrically induced filament in a vanadium dioxide film created strong asymmetric strain in an underlying sapphire substrate. This asymmetric substrate strain fed back into the film ...

摘要：INTRODUCTION: The transatlantic slave trade forcibly displaced >12.5 million Africans, yet the geographic origins and life histories of most remain unknown. Recovering aspects of these erased histories is a priority for descendant communities and scholars. On St Helena, a community- led initiative has focused on recovering and commemorating the lives of the island's liberated Africans-people rescued from illegal slave ships and brought to the island, many of whom died soon after arrival and we...

摘要：Human stem cell-derived miniature organs, including kidney organoids, reproduce aspects of tissue development but lack reliable spatial patterning. In embryos, spatial organization is often established by developmental organizers that generate morphogenetic fields. However, how such organizing geometry operates in kidney nephrogenesis-and whether it can be reconstructed in vitro-has remained unclear. Using spatial transcriptomics of human kidney development, we found that nascent nephrons esta...
