  摘要：The marine-based West Antarctic Ice Sheet (WAIS) is considered vulnerable to irreversible collapse under future climate trajectories, and its tipping point may lie within the mitigated warming scenarios of 1.5 degrees to 2 degrees C of the United Nations Paris Agreement. Knowledge of ice loss during similarly warm past climates could resolve this uncertainty, including the Last Interglacial when global sea levels were 5 to 10 meters higher than today and global average temperatures were 0.5 de...

  摘要：The power conversion efficiency (PCE) of inverted perovskite solar cells (PSCs) is still lagging behind that of conventional PSCs, in part because of inefficient carrier transport and poor morphology of hole transport layers (HTLs). We optimized self-assembly of [4-(3,6-dimethyl-9H-carbazol-9-yl)butyl]phosphonic acid (Me-4PACz) onto nickel oxide (NiOx) nanoparticles as an HTL through treatment with hydrogen peroxide, which created a more uniform dispersion of nanoparticles with high conductivi...

  摘要：Twisted interfaces between stacked van der Waals (vdW) cuprate crystals present a platform for engineering superconducting order parameters by adjusting stacking angles. Using a cryogenic assembly technique, we construct twisted vdW Josephson junctions (JJs) at atomically sharp interfaces between Bi2Sr2CaCu2O8+x crystals, with quality approaching the limit set by intrinsic JJs. Near 45 degrees twist angle, we observe fractional Shapiro steps and Fraunhofer patterns, consistent with the existen...

  摘要：INTRODUCTION During Drosophila aversive olfactory conditioning, flies are exposed simultaneously to an odor and aversive electrical shocks. Flies learn to associate the odor with the aversive stimulus and subsequently avoid the odor. Learning and memory of this association requires a brain region known as the mushroom bodies (MBs). Odor information is conveyed to the MBs by cholinergic projection neurons, which originate in the antennal lobes and synapse onto the dendrites of MB neurons. Howev...
