  摘要：Intracortical microstimulation (ICMS) of somatosensory cortex evokes tactile sensations whose properties can be systematically manipulated by varying stimulation parameters. However, ICMS currently provides an imperfect sense of touch, limiting manual dexterity and tactile experience. Leveraging our understanding of how tactile features are encoded in the primary somatosensory cortex (S1), we sought to inform individuals with paralysis about local geometry and apparent motion of objects on the...

  摘要：Strigolactones (SLs) are methylbutenolide molecules derived from beta-carotene through an intermediate carlactonoic acid (CLA). Canonical SLs act as signals to microbes and plants, whereas noncanonical SLs are primarily plant hormones. The cytochrome P450 CYP722C catalyzes a critical step, converting CLA to canonical SLs in most angiosperms. Using synthetic biology, we investigated the function of CYP722A, an evolutionary predecessor of CYP722C. CYP722A converts CLA into 16-hydroxy-CLA (16-OH-...

  摘要：Formamidinium lead triiodide (FAPbI(3)) is considered the most promising composition for high-performing single-junction solar cells. However, nonalloyed alpha-FAPbI(3) is metastable with respect to the photoinactive delta-phase. We have developed a kinetic modulation strategy to fabricate high-quality and stable nonalloyed alpha-FAPbI(3) films, assisted by cogenetic volatile iodine intercalation and decalation. The intercalation of iodine facilitated the formation of corner-sharing Pb-I frame...
